17-35: Screening and Adverse Selection in Frictional Markets by Benjamin Lester, Ali Shourideh, Venky Venkateswaran, and Ariel Zetlin-Jones

The authors incorporate a search-theoretic model of imperfect competition into a standard model of asymmetric information with unrestricted contracts. They characterize the unique equilibrium, and use their characterization to explore the interaction between adverse selection, screening, and imperfect competition. The authors show that the relationship between an agent’s type, the quantity he trades, and the price he pays is jointly determined by the severity of adverse selection and the concentration of market power. Therefore, quantifying the effects of adverse selection requires controlling for market structure. The authors also show that increasing competition and reducing informational asymmetries can decrease welfare.

17-34: Spatial Commitment Devices and Addictive Goods: Evidence from the Removal of Slot Machines from Bars by Vyacheslav Mikhed, Barry Scholnick, and Hyungsuk Byun

Commitment device theory suggests that temptations to consume addictive goods could be reduced by the regulatory removal of geographically close environmental cues. The authors provide new evidence on this hypothesis using a quasi-natural experiment, in which gambling regulators removed slot machines from some, but not all, neighborhood bars. The authors find that the removal of slot machines reduced personal bankruptcies of close neighbors (within 100 meters) but not neighbors slightly farther away. This is consistent with the removal of neighborhood slots serving as an effective spatial commitment device, which reduced close neighbors' temptation to gamble, thus allowing them to avoid bankruptcy.

17-33: Land-Use Regulations, Property Values, and Rents: Decomposing the Effects of the California Coastal Act by Christopher Severen and Andrew J. Plantinga

Land-use regulations can lower real estate prices by imposing costs on property owners, but may raise prices by restricting supply and generating amenities. The authors study the effects of the California Coastal Act, one of the nation’s most stringent land-use regulations, on prices and rents for multifamily housing units. The Coastal Act applies to a narrow section of the California coast, allowing the authors to compare properties on either side of the jurisdictional boundary. The Coastal Act offers several advantages for measuring the effects of land-use regulations, including plausible exogeneity of the boundary location, which the authors confirm using historical data on boundary placement, and orthogonality of the boundary to other jurisdictional divisions. Extending previous studies, the authors decompose the effects of the regulation into a local effect, the net price effect of restrictions on the subject property and its immediate neighbors, and an external effect, the value of amenities generated by restrictions on all properties within the regulated area. Data on multifamily housing rents are used to isolate the effect of restrictions on adjacent properties (the neighbor effect). The authors' analysis of multifamily housing prices reveals local and external effects of approximately +8% and +5%, respectively. The rent analysis indicates a zero neighbor effect, which suggests that the local benefits of the Coastal Act have not yet materialized but are expected to in the future. This interpretation of the authors' results is supported by additional evidence on building ages and assessed building and land values.

17-32: Localized Knowledge Spillovers: Evidence from the Spatial Clustering of R&D Labs and Patent Citations by Kristy Buzard, Gerald A. Carlino, Robert M. Hunt, Jake K. Carr, and Tony E. Smith

Patent citations are a commonly used indicator of knowledge spillovers among inventors, while clusters of research and development labs are locations in which knowledge spillovers are particularly likely to occur. In this paper, the authors assign patents and citations to newly defined clusters of American R&D labs to capture the geographic extent of knowledge spillovers. Their tests show that the localization of knowledge spillovers, as measured via patent citations, is strongest at small spatial scales and diminishes rapidly with distance. On average, patents within a cluster are about three to six times more likely to cite an inventor in the same cluster than one in a control group. At the same time, the strength of knowledge spillovers varies widely between clusters. The results are robust to the specification of patent technological categories, the method of citation matching and alternate cluster definitions.

17-31: The Role of Startups for Local Labor Markets by Gerald Carlino and Thorsten Drautzburg

The authors investigate the dynamic response of local U.S. labor markets to increased job creation by new firms and compare the effects to overall labor demand shocks. To account for both dynamic and spatial dependence the authors develop a spatial panel VAR that builds on recent advances in the VAR literature to identify structural shocks using external instruments. They find that startup shocks have a small but persistent effect on local employment through population growth. Population growth, in turn, is largely driven by immigration. The authors also investigate how the responses differ by local characteristics such as population density. Finally, they show that startups are not closely linked to innovation.

17-30: Do Non-Compete Covenants Influence State Startup Activity? Evidence from the Michigan Experiment by Gerald A. Carlino

This paper examines how the enforceability of employee non-compete agreements affects the entry of new establishments and jobs created by these new firms. The author uses a panel of startup activity for the U.S. states for the period 1977 to 2013. He exploits Michigan’s inadvertent policy reversal in 1985 that transformed the state from a non-enforcing to an enforcing state as a quasi-natural experiment to estimate the causal effect of enforcement on startup activity. His findings offer little support for the widely held view that enforcement of non-compete agreements negatively affects the entry rate of new firms or the rate of jobs created by new firms. In a difference-in-difference analysis, the author finds that a 10 percent increase in enforcement led to an increase of about 1 percent to about 3 percent in the startup job creation rate in Michigan and, in general, to essentially no change in the startup entry rate. Extending his analysis to consider the effect of increased enforcement on patent activity, the author finds that enforcement had differential effects across technological classifications. Importantly, increased enforcement had a positive and significant effect on the number of quality-adjusted mechanical patents in Michigan, the most important patenting classification in that state.

17-29: Recall and Unemployment by Shigeru Fujita and Giuseppe Moscarini

The authors document in the Survey of Income and Program Participation covering 1990-2013 that a surprisingly large share of workers return to their previous employer after a jobless spell and experience very different unemployment and employment outcomes than job switchers. The probability of recall is much less procyclical and volatile than the probability of finding a new employer. The authors add to a quantitative, and otherwise canonical, search-and-matching model of the labor market a recall option, which can be activated freely following aggregate and job-specific productivity shocks. Recall and search effort significantly amplify the cyclical volatility of new job-finding and separation probabilities.

17-28: Stress Tests and Information Disclosure by Itay Goldstein and Yaron Leitner

The authors study an optimal disclosure policy of a regulator that has information about banks (e.g., from conducting stress tests). In their model, disclosure can destroy risk-sharing opportunities for banks (the Hirshleifer effect). Yet, in some cases, some level of disclosure is necessary for risk sharing to occur. The authors provide conditions under which optimal disclosure takes a simple form (e.g., full disclosure, no disclosure, or a cutoff rule). They also show that, in some cases, optimal disclosure takes a more complicated form (e.g., multiple cutoffs or nonmonotone rules), which they characterize. The authors relate their results to the Bayesian persuasion literature.

17-27: Credit Enforcement Cycles by Lukasz A. Drozd and Ricardo Serrano-Padial

Empirical evidence suggests that widespread financial distress, by disrupting enforcement of credit contracts, can be self-propagatory and adversely affect the supply of credit. The authors propose a unifying theory that models the interplay between enforcement, borrower default decisions, and the provision of credit. The central tenets of their framework are the presence of capacity constrained enforcement and borrower heterogeneity. The authors show that, despite heterogeneity, borrowers tend to coordinate their default choices, leading to fragility and to credit rationing. Their model provides a rationale for the comovement of enforcement, default rates and credit seen in the data.

17-26: Do Phillips Curves Conditionally Help to Forecast Inflation? by Michael Dotsey, Shigeru Fujita, and Tom Stark

This paper reexamines the forecasting ability of Phillips curves from both an unconditional and conditional perspective by applying the method developed by Giacomini and White (2006). The authors find that forecasts from their Phillips curve models tend to be unconditionally inferior to those from their univariate forecasting models. Significantly, the authors also find conditional inferiority, with some exceptions. When the authors do find improvement, it is asymmetric — Phillips curve forecasts tend to be more accurate when the economy is weak and less accurate when the economy is strong. Any improvement they find, however, vanished over the post-1984 period.

17-25: Political Distribution Risk and Aggregate Fluctuations by Thorsten Drautzburg, Jesus Fernandez-Villaverde, and Pablo Guerron-Quintana

The authors argue that political distribution risk is an important driver of aggregate fluctuations. To that end, they document significant changes in the capital share after large political events, such as political realignments, modifications in collective bargaining rules, or the end of dictatorships, in a sample of developed and emerging economies. These policy changes are associated with significant fluctuations in output and asset prices. Using a Bayesian proxy-VAR estimated with U.S. data, the authors show how distribution shocks cause movements in output, unemployment, and sectoral asset prices. To quantify the importance of these political shocks for the U.S. as a whole, the authors extend an otherwise standard neoclassical growth model. They model political shocks as exogenous changes in the bargaining power of workers in a labor market with search and matching. The authors calibrate the model to the U.S. corporate non-financial business sector and they back up the evolution of the bargaining power of workers over time using a new methodological approach, the partial filter. The authors show how the estimated shocks agree with the historical narrative evidence. They document that bargaining shocks account for 34% of aggregate fluctuations.

17-24: Accounting for Growth in the Age of the Internet: The Importance of Output-Saving Technical Change by Charles Hulten and Leonard Nakamura

The authors extend the conventional Solow growth accounting model to allow innovation to affect consumer welfare directly. Their model is based on Lancaster’s New Approach to Consumer Theory, in which there is a separate “consumption technology” that transforms the produced goods, measured at production cost, into utility. This technology can shift over time, allowing consumers to make more efficient use of each dollar of income. This is “output-saving” technical change, in contrast to the Solow TFP “resource-saving” technical change. One implication of the authors' model is that living standards can rise at a greater rate than real GDP growth.

17-23: Appraising Home Purchase Appraisals by Paul S. Calem, Lauren Lambie-Hanson, and Leonard I. Nakamura

Home appraisals are produced for millions of residential mortgage transactions each year, but appraised values are rarely below the purchase contract price. The authors argue that institutional features of home mortgage lending cause much of the information in appraisals to be lost: some 30 percent of recent appraisals are exactly at the home price (with less than 10 percent below it). The authors lay out a novel, basic theoretical framework to explain how lenders’ and appraisers’ incentives lead to information loss in appraisals (that is, appraisals set equal to the contract price). Such information loss is more common at loan-to-value boundaries where mortgage insurance rates increase and appears to be associated with a higher incidence of mortgage default, after controlling for pertinent borrower and loan-level characteristics. Appraisals do, in some cases, improve default risk measurement, but they are less informative than automated valuation models. An important benefit of appraisals reported below the contract price is that they help borrowers renegotiate prices with sellers.

17-22: Concentration of Control Rights in Leveraged Loan Syndicates by Mitchell Berlin, Greg Nini, and Edison G. Yu

Corporate loan contracts frequently concentrate control rights with a subset of lenders. In a large fraction of leveraged loans, which typically include a revolving line of credit and a term loan, the revolving lenders have the exclusive right and ability to monitor and renegotiate the financial covenants in the governing credit agreements. Concentration is more common in loans that include nonbank institutional lenders and in loans originated subsequent to the financial crisis, when recognition of bargaining frictions increased. The authors conclude that concentrated control rights maintain the benefits of lender monitoring and minimize the costs of renegotiation associated with larger and more diverse lending syndicates.

17-21: Household Credit and Local Economic Uncertainty by Marco Di Maggio, Amir Kermani, Rodney Ramcharan, and Edison Yu

This paper investigates the impact of uncertainty on consumer credit outcomes. The authors develop a local measure of economic uncertainty capturing county-level labor market shocks. They then exploit microeconomic data on mortgages and credit-card balances together with the cross-sectional variation provided by their uncertainty measure to show strong borrower-specific heterogeneity in response to changes in uncertainty. Among high risk borrowers or areas with more high risk borrowers, increased uncertainty is associated with housing market illiquidity and a reduction in leverage. For low risk borrowers, these effects are absent and the cost of mortgage credit declines, suggesting that lenders reallocate credit towards safer borrowers when uncertainty spikes. A similar pattern is observed in the unsecured credit market. Taken together, local uncertainty might independently affect aggregate economic activity through consumer credit markets and could engender greater inequality in consumption and housing wealth accumulation across households.

17-20: Banking Panics and Output Dynamics by Daniel Sanches

This paper develops a dynamic general equilibrium model with an essential role for an illiquid banking system to investigate output dynamics in the event of a banking crisis. In particular, it considers the ex-post efficient policy response to a banking crisis as part of the dynamic equilibrium analysis. It is shown that the trajectory of real output following a panic episode crucially depends on the cost of converting long-term assets into liquid funds. For small values of the liquidation cost, the recession associated with a banking panic is protracted as a result of the premature liquidation of a large fraction of productive banking assets to respond to a panic. For intermediate values, the recession is more severe but short-lived. For relatively large values, the contemporaneous decline in real output in the event of a panic is substantial but followed by a vigorous rebound in real activity above the long-run level.

17-19: Not in My Backyard? Not So Fast. The Effect of Marijuana Legalization on Neighborhood Crime by Jeffrey Brinkman and David Mok-Lamme

This paper studies the effects of marijuana legalization on neighborhood crime using unique geospatial data from Denver, Colorado. We construct a highly local panel data set that includes changes in the location of marijuana dispensaries and changes in neighborhood crime. To account for endogenous retail dispensary locations, we use a novel identification strategy that exploits exogenous changes in demand across different locations. The change in geographic demand arises from the increased importance of access to external markets caused by a change in state and local policy. The results imply that retail dispensaries lead to reduced crime in the neighborhoods where they are located. Reductions in crime are highly localized, with no evidence of benefits for adjacent neighborhoods. The spatial extent of these effects are consistent with a policing or security response, and analysis of detailed crime categories provides indirect evidence that the reduction in crime arises from a disruption of illicit markets.

17-18: The Agglomeration of American Research and Development Labs by Kristy Buzard, Gerald A. Carlino, Robert M. Hunt, Jake K. Carr and Tony E. Smith

The authors employ a unique data set to examine the spatial clustering of about 1,700 private research and development (R&D) labs in California and across the Northeast corridor of the United States. Using these data, which contain the R&D labs’ complete addresses, the authors are able to more precisely locate innovative activity than with patent data, which only contain zip codes for inventors’ residential addresses. The authors avoid the problems of scale and borders associated with using fixed spatial boundaries, such as zip codes, by developing a new point pattern procedure. Our multiscale core-cluster approach identifies the location and size of significant R&D clusters at various scales, such as a half mile, one mile, five miles, and more. Our analysis identifies four major clusters in the Northeast corridor (one each in Boston, New York–Northern New Jersey, Philadelphia–Wilmington, and Washington, D.C.) and three major clusters in California (one each in the Bay Area, Los Angeles, and San Diego).

17-17: Fintech Lending: Financial Inclusion, Risk Pricing, and Alternative Information by Julapa Jagtiani and Catharine Lemieux

Fintech has been playing an increasing role in shaping financial and banking landscapes. Banks have been concerned about the uneven playing field because fintech lenders are not subject to the same rigorous oversight. There have also been concerns about the use of alternative data sources by fintech lenders and the impact on financial inclusion. In this paper, the authors explore the advantages/disadvantages of loans made by a large fintech lender and similar loans that were originated through traditional banking channels. Specifically, they use account-level data from the Lending Club and Y-14M bank stress test data. The authors find that Lending Club’s consumer lending activities have penetrated areas that could benefit from additional credit supply, such as areas that lose bank branches and those in highly concentrated banking markets. The authors also find a high correlation with interest rate spreads, Lending Club rating grades, and loan performance. However, the rating grades have a decreasing correlation with FICO scores and debt-to-income ratios, indicating that alternative data is being used and performing well so far. Lending Club borrowers are, on average, more risky than traditional borrowers given the same FICO scores. The use of alternative information sources has allowed some borrowers who would be classified as subprime by traditional criteria to be slotted into “better” loan grades and therefore get lower priced credit. Also, for the same risk of default, consumers pay smaller spreads on loans from the Lending Club than from traditional lending channels.

17-16: Positive Trend Inflation and Determinacy in a Medium-Sized New Keynesian Model by Jonas E. Arias, Guido Ascari, Nicola Branzoli, and Efrem Castelnuovo

This paper studies the challenge that increasing the inflation target poses to equilibrium determinacy in a medium-sized New Keynesian model without indexation fitted to the Great Moderation era. For moderate targets of the inflation rate, such as 2 or 4 percent, the probability of determinacy is near one conditional on the monetary policy rule of the estimated model. However, this probability drops significantly conditional on model-free estimates of the monetary policy rule based on real-time data. The difference is driven by the larger response of the federal funds rate to the output gap associated with the latter estimates.

17-15: “Don't Know What You Got Till It’s Gone” — The Effects of the Community Reinvestment Act (CRA) on Mortgage Lending in the Philadelphia Market by Lei Ding and Leonard Nakamura

The Community Reinvestment Act (CRA), enacted in 1977, has served as an important tool to foster access to financial services for lower-income communities across the country. This study provides new evidence on the effectiveness of CRA on mortgage lending by focusing on a large number of neighborhoods that became eligible and ineligible for CRA credit in the Philadelphia market because of an exogenous policy shock in 2014. The CRA effects are more evident when a lower-income neighborhood loses its CRA coverage, which leads to a 10 percent or more decrease in purchase originations by CRA-regulated lenders. Lending institutions not subject to CRA can substitute approximately half, but not all, of the decreased lending by CRA lenders. The increased market share of nondepository institutions in previously CRA eligible neighborhoods, however, was accompanied by a greater involvement in riskier Federal Housing Administration lending. This study demonstrates how different lenders respond to the incentive of CRA credit and how the use of metropolitan division median family incomes can generate unintended consequences on CRA lending activities.

17-14: Reorganization or Liquidation: Bankruptcy Choice and Firm Dynamics by Dean Corbae and Pablo D’Erasmo

In this paper, the authors ask how bankruptcy law affects the financial decisions of corporations and its implications for firm dynamics. According to current U.S. law, firms have two bankruptcy options: Chapter 7 liquidation and Chapter 11 reorganization. Using Compustat data, the authors first document capital structure and investment decisions of non-bankrupt, Chapter 11, and Chapter 7 firms. Using those data moments, they then estimate parameters of a firm dynamics model with endogenous entry and exit to include both bankruptcy options in a general equilibrium environment. Finally, the authors evaluate a bankruptcy policy change recommended by the American Bankruptcy Institute that amounts to a "fresh start" for bankrupt firms. The authors find that changes to the law can have sizable consequences for borrowing costs and capital structure, which via selection affects productivity (allocative efficiency rises by 2.58%) and welfare (rises by 0.54%).

17-13: Fiscal Surprises at the FOMC by Dean Croushore and Simon van Norden

This paper provides a detailed examination of a new set of fiscal forecasts for the U.S. assembled by Croushore and van Norden (2017) from FOMC briefing books. The data are of particular interest because (1) they afford a look at fiscal forecasts over six complete business cycles and several fiscal policy regimes, covering both peacetime and several wars, (2) the forecasts were precisely those presented to monetary policymakers, (3) they include frequently updated estimates of both actual and cyclically adjusted deficits, (4) unlike most other U.S. fiscal forecasts, they were neither partisan nor constrained by unrealistic assumptions about future fiscal policy, and (5) forecasts for other variables (GDP growth, inflation) from the same forecasters are known to compare favorably with most other available forecasts.

The authors detail the performance of forecast federal expenditures, revenues, surpluses, and structural surpluses in terms of accuracy, bias, and efficiency. They find that (1) fiscal forecast errors can be economically large, even at relatively short forecast horizons, (2) while the accuracy of unemployment rate forecast errors improved after 1990, that of most fiscal variables deteriorated considerably, (3) there is limited evidence of forecast bias, and most of this evidence is confined to the period before 1993, (4) the forecasts appear to be efficient with respect to both the fed funds rate and CBO projections, and (5) cyclically adjusted deficit forecasts appear to be over-optimistic around both business cycle peaks and troughs.

17-12: Where Do Students Go When For-Profit Colleges Lose Federal Aid? by Stephanie R. Cellini, Rajeev Darolia, and Lesley J. Turner

Recent federal investigations and new regulations have resulted in restrictions on for-profit institutions' access to federal student aid. The authors examine the enrollment effects of similar restrictions imposed on over 1,200 for-profit colleges in the 1990s. Using variation in regulations linked to student loan default rates, the authors estimate the impact of the loss of federal aid on the enrollment of Pell Grant recipients in sanctioned institutions and their local competitors. Enrollment in a sanctioned for-profit college declines by 53 percent in the five years following a sanction. For-profit sanctions result in negative spillovers on unsanctioned competitor for-profit colleges in the same county, which experience modest enrollment declines. These enrollment losses in the for-profit sector are offset by gains in enrollment in local community colleges, suggesting that the loss of federal student aid for poor-performing for-profit colleges does not reduce overall college-going but instead shifts students across higher education sectors. Finally, the authors provide suggestive evidence that students induced to enroll in community colleges following a for-profit competitor’s sanction are less likely to default on their federal loans.

17-11: Identification Through Heterogeneity by Pooyan Amir-Ahmadi and Thorsten Drautzburg

The authors analyze set identification in Bayesian vector autoregressions (VARs). Because set identification can be challenging, they propose to include micro data on heterogeneous entities to sharpen inference. First, the authors provide conditions when imposing a simple ranking of impulse-responses sharpens inference in bivariate and trivariate VARs. Importantly, they show that this set reduction also applies to variables not subject to ranking restrictions. Second, the authors develop two types of inference to address recent criticism: (1) an efficient fully Bayesian algorithm based on an agnostic prior that directly samples from the admissible set and (2) a prior-robust Bayesian algorithm to sample the posterior bounds of the identified set. Third, they apply our methodology to U.S. data to identify productivity news and defense spending shocks. The authors find that under both algorithms, the bounds of the identified sets shrink substantially under heterogeneity restrictions relative to standard sign restrictions.

17-10: The Impacts of Financial Regulations: Solvency and Liquidity in the Post-crisis Period by Colleen Baker, Christine Cumming, and Julapa Jagtiani

This paper discusses the new financial regulations in the post–financial crisis period, focusing on capital and liquidity regulations. Basel III and the capital stress tests introduced new requirements and new definitions while retaining the structure of the pre-2010 requirements. The total number of requirements increased, making it difficult to determine which constraints are binding. The authors find that the new common equity tier 1 (CET1) and Level 1 high-quality liquid assets (HQLAs) are the binding constraints at large U.S. banks, especially for banks that are active in capital markets activities. Banks have been holding more CET1 and a larger share of Level 1 HQLAs since the financial crisis of 2007 to 2009. The authors also find that the market pricing of bank debt appears to have responded to changes in liquidity measures, especially at large capital markets banks. The Basel III regulatory capital ratios appear to have little direct influence on spreads.

17-09: Endogenous/Exogenous Segmentation in the A-IRB Framework and the Pro-cyclicality of Capital: An Application to Mortgage Portfolios by José J. Canals-Cerdá

This paper investigates the pro-cyclicality of capital in the advanced internal ratings-based (A-IRB) Basel approach for retail portfolios and identifies the fundamental assumptions required for stable A-IRB risk weights over the economic cycle. Specifically, it distinguishes between endogenous and exogenous segmentation risk drivers and, through application to a portfolio of first mortgages, shows that risk weights remain stable over the economic cycle when the segmentation scheme is derived using exogenous risk drivers, while segmentation schemes that include endogenous risk drivers are highly pro-cyclical. Also analyzed is the sensitivity of the A-IRB framework to model risk resulting from the selection, at the quantification stage, of a data sample period that does not include a period of significant economic downturn. The analysis illustrates important limitations and sensitivities of the A-IRB framework and sheds light on the implicit restrictions embedded in recent regulatory guidance that underscore the importance of rating systems that remain stable over time and throughout business cycles.

17-08: Regime Shift and the Post-crisis World of Mortgage Loss Severities by Xudong An and Larry Cordell

The average loss rate for conventional mortgages rose from less than 10% pre-crisis to more than 30% during the crisis, reaching and sustaining greater than 40% post-crisis. Using a novel database that contains the components of mortgage losses, the authors identify a regime shift in loss severities caused by various government interventions and changes in business practices in the servicing industry. This regime shift helps explain the persistently high loss severities post-crisis, even after a strong recovery in the housing market. The authors' findings have implications for loss modeling, pricing, and, potentially, mortgage credit availability.

17-07: Self-Fulfilling Debt Crises, Revisited: The Art of the Desperate Deal by Mark Aguiar, Satyajit Chatterjee, Harold Cole, and Zachary Stangebye

The authors revisit self-fulfilling rollover crises by introducing an alternative equilibrium selection that involves bond auctions at depressed but strictly positive equilibrium prices, a scenario in line with observed sovereign debt crises. They refer to these auctions as "desperate deals," the defining feature of which is a price schedule that makes the government indifferent to default or repayment. The government randomizes at the time of repayment, which the authors show can be implemented in pure strategies by introducing stochastic political payoffs or external bailouts. Quantitatively, auctions at fire-sale prices are crucial for generating realistic spread volatility.

17-06: How Data Breaches Affect Consumer Credit by Vyacheslav Mikhed and Michael Vogan

The authors use the 2012 South Carolina Department of Revenue data breach as a natural experiment to study how data breaches and news coverage about them affect consumers' interactions with the credit market and their use of credit. They find that some consumers directly exposed to the breach protected themselves against potential losses from future fraudulent use of stolen information by monitoring their files and freezing access to their credit reports. However, these consumers continued their regular use of existing credit cards and did not switch lenders. The response of consumers exposed to the news about the breach only was negligible.

17-05: Market Discipline in the Secondary Bond Market: The Case of Systemically Important Banks by Elyas Elyasiani and Jason M. Keegan

The authors investigate the association between the yields on debt issued by U.S. systemically important banks (SIBs) and their idiosyncratic risk factors, macroeconomic factors, and bond features in the secondary market. Although greater SIB risk levels are expected to increase debt yields (Evanoff and Wall, 2000), prevalence of government safety nets complicates the market discipline mechanism, rendering the issue an empirical exercise. Their main objectives are twofold. First, they study how bond buyers reacted to elevation of SIB-specific and macroeconomic risk factors over the recent business cycle. Second, they investigate the degree to which the proportion of variance in yields explained by SIB and macroeconomic risk factors changed across the phases of the cycle. Their data include over 8 million bond trades across 26 SIBs. The authors divide their sample period into the pre-crisis (2003:Q1 to 2007:Q3), crisis (2007:Q4 to 2009:Q2), and post-crisis (2009:Q3 to 2014:Q3) sub-periods to contrast the findings. They obtain several results. First, bond buyers do react to changes in the SIB-specific risk factors (leverage, credit risk, inefficiency, lack of profitability, illiquidity, and interest rate risk) by demanding higher yields. Second, bond buyers’ responses to risk factors are sensitive to the phase of the business cycle. Third, the proportion of variance in yields driven by SIB-specific and bond-specific risk factors increased from 23 percent in the pre-crisis period to 47 percent and 73 percent, respectively, during the crisis and post-crisis periods. These findings indicate that the force of market discipline improved greatly during the crisis and post-crisis periods, at the expense of macroeconomic factors. The strengthening of market discipline in the crisis and post-crisis periods, despite the unprecedented regulatory intervention in the form of quantitative easing programs, the Troubled Asset Relief Program, large bailouts, and generally accommodative fiscal and monetary policies adopted during these periods, demonstrates that regulatory intervention and market discipline can work in tandem.

17-04: Optimal Domestic (and External) Sovereign Default by Pablo D’Erasmo and Enrique G. Mendoza

Infrequent but turbulent episodes of outright sovereign default on domestic creditors are considered a “forgotten history” in macroeconomics. The authors propose a heterogeneous-agents model in which optimal debt and default on domestic and foreign creditors are driven by distributional incentives and endogenous default costs due to value of debt for self-insurance, liquidity, and risk-sharing. The government’s aim to redistribute resources across agents and through time in response to uninsurable shocks produces a rich dynamic feedback mechanism linking debt issuance, the distribution of government bond holdings, the default decision, and risk premia. Calibrated to Spanish data, the model is consistent with key cyclical comovements and features of debt-crisis dynamics. Debt exhibits protracted fluctuations. Defaults have a low frequency of 0.93 percent, are preceded by surging debt and spreads, and occur with relatively low external debt. Default risk limits the sustainable debt, and yet spreads are zero most of the time.

17-03: Natural Amenities, Neighborhood Dynamics, and Persistence in the Spatial Distribution of Income by Sanghoon Lee and Jeffrey Lin

The authors present theory and evidence highlighting the role of natural amenities in neighborhood dynamics, suburbanization, and variation across cities in the persistence of the spatial distribution of income. Their model generates three predictions that they confirm using a novel database of consistent-boundary neighborhoods in U.S. metropolitan areas, 1880-2010, and spatial data for natural features such as coastlines and hills. First, persistent natural amenities anchor neighborhoods to high incomes over time. Second, naturally heterogeneous cities exhibit persistent spatial distributions of income. Third, downtown neighborhoods in coastal cities were less susceptible to the widespread decentralization of income in the mid-20th century and experienced an increase in income more quickly after 1980.

17-02: Modeling the Revolving Revolution: Debt Collection Channel by Lukasz A. Drozd and Ricardo Serrano-Padial

The authors investigate the role of information technology (IT) in the collection of delinquent consumer debt. They argue that the widespread adoption of IT by the debt collection industry in the 1990s contributed to the observed expansion of unsecured risky lending such as credit cards. The authors' model stresses the importance of delinquency and private information about borrower solvency. The prevalence of delinquency implies that the costs of debt collection must be borne by lenders to sustain incentives to repay debt. IT mitigates informational asymmetries, allowing lenders to concentrate collection efforts on delinquent borrowers who are more likely to repay.

17-01: Endogenous Political Turnover and Fluctuations in Sovereign Default Risk by Satyajit Chatterjee and Burcu Eyigungor

A sovereign default model in which the sovereign derives private benefits from public office and contests elections to stay in power is developed. The economy’s growth process is modeled as a Markov switching regime, which is shown to be a better description of the data for the authors' set of emerging economies. In the model, consistent with evidence, the sovereign is less likely to be reelected if economic growth is weak. In the low-growth regime, there is higher probability of loss of private benefits due to turnover, which makes the sovereign behave more myopically. This growth-linked variation in effective discount factor is shown to be important in generating volatility in sovereign spreads.
