Evergreening
We develop a simple model of relationship lending where lenders have incentives for evergreening loans by offering better terms to less productive and more indebted firms. We detect such lending behavior using loan-level supervisory data for the United States. Low-capitalized banks systematically distort firms’ risk assessments to window-dress their balance sheets. To avoid further reductions in their capital ratios, such banks extend relatively more credit to underreported borrowers. We incorporate the theoretical mechanism into a dynamic heterogeneous-firm model to show that evergreening ...

Tax Heterogeneity and Misallocation
Companies face different effective marginal tax rates on their income. This can be detrimental to allocative efficiency unless taxes offset other distortions in the economy. This paper estimates the effect of tax rate heterogeneity on aggregate productivity in distorted economies with multiple frictions. Using firm-level balance-sheet data and estimates of marginal tax rates, we find that tax heterogeneity reduces total factor productivity by about 3 percent. Our findings highlight the positive correlation between marginal tax rates and other distortions to capital and especially labor. This ...

Risk-Adjusted Capital Allocation and Misallocation
We develop a theory linking “misallocation,” i.e., dispersion in marginal products of capital (MPK), to macroeconomic risk. Dispersion in MPK depends on (i) heterogeneity in firm-level risk premia and (ii) the price of risk, and thus is countercyclical. We document strong empirical support for these predictions. Stock market-based measures of risk premia imply that risk considerations explain about 30% of observed MPK dispersion among US firms and rationalize a large persistent component in firm-level MPK. Risk-based MPK dispersion, although not prima facie inefficient, lowers long-run ...

Risk, Financial Development and Firm Dynamics
I document that the average productivity of firms tends to increase, and its variance to decrease, as they age. These two facts combined suggest that managers learn to reduce their mistakes as they operate. I develop a quantitative framework mimicking these dynamics and find that young firms have substantially higher financing costs due to lower and riskier returns. In this scenario, a reduction in the financial development of an economy raises disproportionately the cost of credit of young-productive firms increasing the input misallocation within this subgroup. To test the validity of the ...

The Economic Gains from Equity
How much is inequity costing us? Using a simple growth accounting framework we apply standard shift-share techniques to data from the Current Population Survey (1990-2019) to compute the aggregate economic costs of persistent educational and labor market disparities by gender and race. We find significant economic losses associated with these gaps. Building on this finding, we consider which disparities generate the largest costs, paying specific attention to differences in employment, hours worked, educational attainment, educational utilization, and occupational allocation. We also examine ...

Immigrant Misallocation
We quantify the barriers that impede the integration of immigrants into foreign labor markets and investigate their aggregate implications. We develop a model of occupational choice with natives and immigrants of multiple types whose decisions are subject to wedges which distort their allocation across occupations. We estimate the model to match salient features of U.S. and cross-country individual-level data. We find that there are sizable GDP gains from removing the wedges faced by immigrants in U.S. labor markets, accounting for approximately one-fifth of the overall economic contribution ...

Scalable vs. Productive Technologies
Do larger firms have more productive technologies or are their technologies more scalable, or both? We use administrative data on Canadian and US firms to estimate flexible nonparametric production functions. Our estimation results in a joint distribution of output elasticities of capital, labor, and intermediate inputs---therefore, returns to scale (RTS)---along with total factor productivity (TFP). We find significant heterogeneity in both RTS and TFP across firms. Larger firms operate technologies with higher RTS, both across and within industries. Higher RTS for large firms are entirely ...

Evergreening
We develop a simple model of relationship lending where lenders have an incentive to evergreen loans by offering better terms to less productive and more indebted firms. We detect such lending distortions using loan-level supervisory data for the United States. Low-capitalized banks systematically distort their risk assessments of firms to window-dress their balance sheets and extend relatively more credit to underreported borrowers. Consistent with our theoretical predictions, these effects are driven by larger outstanding loans and low-productivity firms. We incorporate the theoretical ...

Evergreening
We develop a simple model of concentrated lending where lenders have incentives for evergreening loans by offering better terms to firms that are close to default. We detect such lending behavior using loan-level supervisory data for the United States. Banks that own a larger share of a firm’s debt provide distressed firms with relatively more credit at lower interest rates. Building on this empirical validation, we incorporate the theoretical mechanism into a dynamic heterogeneous-firm model to show that evergreening affects aggregate outcomes, resulting in lower interest rates, higher ...

Risk-Taking, Capital Allocation and Optimal Monetary Policy
We study the role of firm heterogeneity in affecting business cycle dynamics and optimal stabilization policy. Firms differ in their degree of cyclicality, and hence, exposure to aggregate risk, leading to firm-specific risk premia that influence resource allocations. The heterogeneous firm economy can be recast in a representative firm formulation, but where total factor productivity (TFP) is endogenous and depends on the resource allocation. The model uncovers a novel tradeoff between the long-run level and volatility of TFP. Inefficiencies distort this tradeoff and result in either ...
