Firm Dynamics and SOE Transformation During China's Economic Reform
We study China’s state-owned enterprises (SOE) reform with a focus on the corporatization of SOEs. We first empirically document that small SOEs are more likely to exit or become privatized, whereas big SOEs are more likely to be corporatized while remaining under state ownership. We then build a heterogeneous-firm model featuring financial frictions, endogenous entry and exit, and optimal firm-type choices. Our calibrated model suggests that in the long run, the SOE reform increases the aggregate output by facilitating resource reallocation to the private sector. Along the transition, the ...

Aggregate Consequences of Dynamic Credit Relationships
Which financial frictions matter in the aggregate? This paper presents a general equilibrium model in which entrepreneurs finance a firm with a long-term contract. The contract is constrained efficient because firm revenue is costly to monitor and entrepreneurs may default. The cost of monitoring firms and the entrepreneurs' outside options determine the significance of moral hazard relative to limited enforcement for financial contracting. Calibrating the model to the U.S. economy, I find that the relative welfare loss from financial frictions is about 5 percent in terms of aggregate ...

Bank Capital Pressures, Loan Substitutability, and Nonfinancial Employment
We exploit the cross-state, cross-time variation in bank tangible capital ratios-brought about by bank branch deregulation on a state-by-state basis-to identify the effects of bank capital pressures on employment and firm dynamics during two waves of changes in bank capital regulation. We show that stronger capital pressures temporarily slowed down growth in employment in industries that depend on external finance, retarding growth in the average size of firms rather than in the number of firms. Such effects were particularly strong for smaller firms that may not have had access to national ...

Grown-up business cycles
We document two striking facts about U.S. firm dynamics and interpret their significance for employment dynamics. The first is the dramatic decline in firm entry and the second is the gradual shift of employment toward older firms since 1980. We show that despite these trends, the lifecycle dynamics of firms and their business cycle properties have remained virtually unchanged. Consequently, aging is the delayed effect of accumulating startup deficits. Together, the decline in the employment contribution of startups and the shift of employment toward more mature firms contributed to the ...

Connecting to Power: Political Connections, Innovation, and Firm Dynamics
How do political connections affect firm dynamics, innovation, and creative destruction? To answer this question, we build a firm dynamics model, where we allow firms to invest in innovation and/or political connection to advance their productivity and to overcome certain market frictions. Our model generates a number of theoretical testable predictions and highlights a new interaction between static gains and dynamic losses from rent-seeking in aggregate productivity. We test the predictions of our model using a brand-new dataset on Italian firms and their workers. Our dataset spans the ...

Nonlinear Firm Dynamics
This paper presents empirical evidence on the nature of idiosyncratic shocks to firms and discusses its role for firm behavior and aggregate fluctuations. We document that firm-level sales and productivity are hit by heavy-tailed shocks and follow a nonlinear stochastic process, thus departing from the canonical linear. We estimate a state-of-the-art model to flexibly capture the rich dynamics uncovered in the data and characterize the drivers of nonlinear persistence and non-Gaussian shocks. We show that these features are crucial to get empirically plausible volatility and persistence of ...

Weathering the Storm: Supply Chains and Climate Risk
We characterize how firms structure supply chains under climate risk. Using new data on the universe of firm-to-firm transactions from an Indian state, we show that firms diversify sourcing locations, and suppliers exposed to climate risk charge lower prices. Our event-study analysis finds that firms with suppliers in flood-affected districts experience a decline in inputs lasting two months, followed by a return to original suppliers. We develop a general equilibrium model of firm input sourcing under climate risk. Firms diversify identical inputs from suppliers across space, trading off the ...

Leverage over the Firm Life Cycle, Firm Growth, and Aggregate Fluctuations
We study the leverage of U.S. firms over their life cycles and the connection between firm leverage, firm growth, and aggregate shocks. We construct a new dataset that combines private and public firms' balance sheets with firm-level data from U.S. Census Bureau's Longitudinal Business Database for the period 2005-12. Public and private firms exhibit different leverage dynamics over their life cycles. Firm age and size are systematically related to leverage for private firms but not for public firms. We show that private firms, but not public ones, deleveraged during the Great Recession and ...

The Firm Size and Leverage Relationship and Its Implications for Entry and Business Concentration
Larger firms (by sales or employment) have higher leverage. This pattern is explained using a model in which firms produce multiple varieties and borrow with the option to default against their future cash flow. A variety can die with a constant probability, implying that bigger firms (those with more varieties) have a lower coefficient of variation of sales and higher leverage. A lower risk-free rate benefits bigger firms more as they are able to lever more and existing firms buy more of the new varieties arriving into the economy. This leads to lower startup rates and greater concentration ...

Firm Dynamics and SOE Transformation During China’s Economic Reform
We study the reform of China’s state-owned enterprises (SOE) with a focus on the corporatization of SOEs. We first document the empirical patterns of the "grasp the large and let go of the small" policy. To quantify the implications of the reform for aggregate output and TFP, we build a three-sector firm dynamics model featuring financial frictions and endogenous firm-type choices. Our calibrated model shows that the SOE reform can increase long-run TFP by encouraging the exit of the least efficient firms in the state sector, but the magnitude of TFP growth also depends on the efficiency in ...
