Misallocation and Credit Market Constraints: the Role of Long-Term Financing
We measure aggregate productivity loss due to credit market constraints in a model with endogenous borrowing constraints, long-duration bonds, and costly equity payouts. Due to long-duration bonds, the model generates a realistic distribution of credit spreads. We structurally estimate our model using firm-level data on credit spreads from Thomson Reuters Bond Security Data and balance sheet data from Compustat. Credit market constraints increase aggregate productivity by 0.4% through their effect on the credit spread distribution. However, credit market constraints also interact with costly ...

Working hard in the wrong place: a mismatch-based explanation to the UK productivity puzzle
The UK experienced an unusually prolonged stagnation in labor productivity in the aftermath of the Great Recession. This paper analyzes the role of sectoral labor misallocation in accounting for this ?productivity puzzle.? If jobseekers disproportionately search for jobs in sectors where productivity is relatively low, hires are concentrated in the wrong sectors and the post-recession recovery in aggregate productivity can be slow. Our calculations suggest that, quantified at the level of three-digit occupations, this mechanism can explain up to two-thirds of the deviations from trend-growth ...

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 ...

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 ...

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-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 ...

The Crowding-In Effects of Local Government Debt in China
We study how changes in the composition of Chinese local government debt influenced bank risk taking, credit allocation, and local productivity. Using confidential loan-level data and a difference-in-difference identification approach, we show that a debt-to-bond swap program for local governments implemented in 2015 significantly increased bank risk taking through a risk-weighting channel under Basel III capital regulations. The debt swap program converted bank holdings of municipal corporate debt to local government bonds, reducing banks’ risk-weighted assets. Banks responded by lowering ...

The Cost of Capital and Misallocation in the United States
We develop a methodology to estimate the cost of capital using credit registry microdata, and apply it to study capital allocation efficiency in the United States. Our measure incorporates the contractual interest rate, expected default probability, recovery rate, and expectations of future rates. We estimate three distinct rates: (i) the lender's discount rate, (ii) the firm's cost of capital, and (iii) the social cost of capital. We derive a sufficient statistic for misallocation based on the first and second moments of the social cost of capital. Dispersion in this rate captures both ...

Scalable versus Productive Technologies
CORRECT ORDER OF AUTHORS: Hubmer, Chan, Ozkan, Salgado, Hong. Are larger firms more productive, more scalable, or both? We use firm-level panel data from thirteen countries and employ a broad set of methods to estimate factor elasticities---capturing returns to scale (RTS)---and total factor productivity (TFP). We find substantial RTS heterogeneity within industries, with larger firms exhibiting higher RTS driven by greater intermediate input elasticities. TFP, by contrast, rises with firm size only up to the top decile before declining. Incorporating RTS heterogeneity into a standard model ...

Scalable versus Productive Technologies
CORRECT ORDER OF AUTHORS: Hubmer, Chan, Ozkan, Salgado, Hong. Do larger firms have more productive technologies, are their technologies more scalable, or both? We use administrative data on Canadian and US firms to estimate a joint distribution of output elasticities of capital, labor, and intermediate inputs—thus, returns to scale (RTS)—along with total factor productivity (TFP). We find significant heterogeneity in RTS across firms within industries. Furthermore, larger firms operate technologies with higher RTS, whereas the largest firms do not exhibit the highest TFP. Higher RTS for ...
