We quantify the importance of imperfect competition in the US labor market by estimating the size of labor market rents earned by American firms and workers. We construct a matched employer-employee panel dataset by combining the universe of US business and worker tax records for the period 2001–2015. Using this panel data, we identify and estimate an equilibrium model of the labor market with two-sided heterogeneity where workers view firms as imperfect substitutes because of heterogeneous preferences over nonwage job characteristics. The model allows us to draw inference about imperfect competition, worker sorting, compensating differentials, and rent sharing.

This paper studies equilibrium selection in the retail gasoline industry. We exploit a unique dataset that contains the universe of station-level prices for an urban market for 15 years, and that encompasses a coordinated equilibrium transition mid-sample. We uncover a gradual, three-year equilibrium transition, whereby dominant firms use price leadership and price experiments to create focal points that coordinate market prices, soften price competition, and enhance retail margins. Our results inform the theory of collusion, with particular relevance to the initiation of collusion and equilibrium selection. We also highlight new insights into merger policy and collusion detection strategies.

By how much does an extension of unemployment benefits affect macroeconomic outcomes such as unemployment? Answering this question is challenging because U.S. law extends benefits for states experiencing high unemployment. We use data revisions to decompose the variation in the duration of benefits into the part coming from actual differences in economic conditions and the part coming from measurement error in the real-time data used to determine benefit extensions. Using only the variation coming from measurement error, we find that benefit extensions have a limited influence on state-level macroeconomic outcomes. We apply our estimates to the increase in the duration of benefits during the Great Recession and find that they increased the unemployment rate by at most 0.3 percentage point.

Analyzing account-level data from an account aggregator, we find that households increase consumption when they receive expected tax refunds, as if they face liquidity constraints. However, these same households smooth consumption when making payments in other years, primarily by transferring funds among liquid accounts. Even households carrying credit card debt smooth consumption when making payments, and even highly liquid households spend out of refunds. This behavior is inconsistent with pure liquidity constraints or hand-to-mouth behavior and is most consistent with a mental accounting life-cycle model.

Using a large panel of more than 140,000 state-owned enterprises (SOEs), this study examines SOEs’ investment behavior surrounding 82 national elections in 25 European countries between 2001 and 2015. We find that SOEs increase their corporate investment by about 29% of the sample average during national election years. This effect is more pronounced in fixed timing and closely contested elections. The effect is also stronger in countries with low institutional quality, more centralized political systems, and state-controlled banking systems. In contrast, we find the matched non-SOEs significantly decrease their corporate investment during national election years.

This paper exploits quasi-experimental variation in tariffs in southern Africa to estimate trade elasticities. Traded quantities respond only weakly to a 30 percent reduction in the average nominal tariff rate. Trade flow data combined with primary data on firm behavior and bribe payments suggest that corruption is a potential explanation for the observed low elasticities. In contexts of pervasive corruption, even small bribes can significantly reduce tariffs, making tariff liberalization schemes less likely to affect the extensive and the intensive margins of firms ' import behavior. The tariff liberalization scheme is, however, still associated with improved incentives to accurately report quantities of imported goods, and with a significant reduction in bribe transfers from importers to public officials.

This paper documents a number of key facts about the evolution of mortgage debt, homeownership, debt burden, and subsequent delinquency during the recent housing boom and Great Recession. We show that the mortgage expansion was shared across the entire income distribution; that is, the flow and stock of debt rose across all income groups (except for the top 5%). The mortgage expansion was especially pronounced in areas with increased house prices, and the speed at which houses turned over (churn) in these areas went up significantly. However, the average loan-to-value ratios (LTV) at origination did not increase over the boom period. While homeownership rates increased for the middle- and upper-income households, there was no increase in homeownership for the lowest income groups. Finally, default rates postcrisis went up predominantly in areas with large house price drops, especially for high-income and high-FICO borrowers. These results are consistent with a view that the run-up in mortgage debt over the precrisis period was driven by rising home values and expectations of increasing prices.

This paper finds that declining bank equity or liquidity reduces liquidation values of bankowned real estate and accelerates the pace of asset sales. Buyers of these assets earn significant returns for providing liquidity to banks, as prices tend to rebound sharply after sales by illiquid banks. Lower liquidation values also depress the prices of nearby real estate transactions. Policy interventions, such as equity injections and central bank asset purchases, increase liquidation values by providing institutions with the balance sheet capacity to slow asset sales. This evidence suggests that balance sheet adjustments at financial institutions can explain real asset price dynamics.

Because the data show that market tightness is not orthogonal to unemployment, this paper identifies the many empirical difficulties caused by adopting the free entry of vacancies assumption in the Diamond-Mortensen-Pissarides (DMP) framework. Relaxing the free entry assumption and using Simulated Method of Moments (SMM) finds the vacancy creation process is less than infinitely elastic. Because a recession-leading job separation shock then causes vacancies to fall as unemployment increases, the ad hoc restriction to zero job separation shocks (to generate Beveridge curve dynamics) becomes redundant. In contrast to standard arguments, the calibrated model finds the job separation process drives unemployment volatility over the cycle.

This study examines the importance of incorporating age-earnings profiles into the estimation of future earnings. Using data from the 2000 Census of the Population and the 2001-2015 American Community Surveys, we estimate ageearnings profiles for seven different education groups after controlling for period and cohort effects. We compare estimates of the loss in future earnings using the age-earnings profiles versus two popular alternatives: assuming a constant rate of earnings growth across the life-cycle or using cross-sectional data for age groups to estimate wage growth for various age ranges. Our results imply that a failure to incorporate the age-earnings profile into estimates of earnings losses can lead to significant over- or under-statement of losses depending on the age at which the damages begin and the educational attainment of the injured party.
