World Productivity: 1996 - 2014

We account for the sources of world productivity growth, using data for more than 36 industries and 40 major economies from 1996 to 2014, explicitly taking into account changes in the misallocation of resources in labor, capital, and product markets. Productivity growth in advanced economies slowed but emerging markets grew more quickly which kept global productivity growth relatively constant until around 2010. After that, productivity growth in all major regions slowed. Much of the volatility in world productivity growth reflects shifts in the misallocation of labor across countries and ...

Working Paper
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 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 ...

Working Paper
Bad Jobs and Low Inflation

We study a model in which firms compete to retain and attract workers searching on the job. A drop in the rate of on-the-job search makes such wage competition less likely, reducing expected labor costs and lowering inflation. This model explains why inflation has remained subdued over the last decade, which is a conundrum for general equilibrium models and Phillips curves. Key to this success is the observed slowdown in the recovery of the employment-to-employment transition rate in the last five years, which is interpreted by the model as a decline in the share of employed workers searching ...

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 ...

Working Paper
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 ...

Working Paper
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 ...
