Firms’ Precautionary Savings and Employment during a Credit Crisis
Can the macroeconomic effects of credit supply shocks be large even when a small share of firms are credit-constrained? I use U.K. firm-level accounting data to discipline a heterogeneous-firm model where the interaction between real and financial frictions induces precautionary cash holdings. In the data, firms increased their cash ratios during the last recession, and cash-intensive firms displayed higher employment growth. A tightening of firms’ credit conditions generates the same dynamics in the model. Unconstrained firms pre-emptively respond to credit supply shocks; this ...

Firm Heterogeneity and the Impact of Immigration: Evidence from German Establishments
We use a detailed establishment-level dataset from Germany to document a new dimension of firm heterogeneity: large firms spend a higher share of their wage bill on immigrants than small firms. We show analytically that ignoring this heterogeneity in the immigrant share leads to biased estimates of the welfare gains from immigration. To do so, we set up and estimate a model where heterogeneous firms choose their immigrant share and then use it to quantify the welfare effects of an increase in the number of immigrants in Germany. Two new adjustment mechanisms arise under firm ...

Forward Looking Exporters
This paper studies the role of expectations in driving export adjustment. We assemble bilateral data on spot exchange rates, one year ahead exchange rate forecasts and HS2-product export data for 11 exporting countries and 64 destinations, covering the 2006–2014 period. Results from fixed effects regressions and an instrumental variables approach show that expectations of exchange rate changes are an important channel for export adjustment. A one percent expected exchange rate depreciation over the next year is associated with a 0.96 percent increase in the extensive margin (entry of new ...

Liquidity Premia, Price-Rent Dynamics, and Business Cycles
n the U.S. economy during the past 25 years, house prices exhibit fluctuations considerably larger than house rents, and these large fluctuations tend to move together with business cycles. We build a simple theoretical model to characterize these observations by showing the tight connection between price-rent fluctuation and the liquidity constraint faced by productive firms. After developing economic intuition for this result, we estimate a medium-scale dynamic general equilibrium model to assess the empirical importance of the role the price-rent fluctuation plays in the business cycle. ...

Offshore Production and Business Cycle Dynamics with Heterogeneous Firms
To examine the effect of offshoring through vertical FDI on the international transmission of business cycles, I propose a two-country model in which firms endogenously choose the location of their production plants over the business cycle. Firms face a sunk cost to enter the domestic market and an additional fixed cost to produce offshore. As such, the offshoring decision depends on the firm-specific productivity and on fluctuations in the relative cost of effective labor. The model generates a procyclical pattern of offshoring and dynamics along its extensive margin that are consistent with ...

Discount Shock, Price-Rent Dynamics, and the Business Cycle
The price-rent ratio in commercial real estate is highly volatile, and its variation comoves with the business cycle. To account for these two facts, we develop a dynamic general equilibrium model that explicitly introduces a rental market and incorporates the liquidity constraint on an individual firm's production as a key ingredient. Our estimation identifies the discount shock as the most important factor in driving price-rent dynamics and linking the dynamics in the real estate market to those in the real economy. We illustrate the importance of the liquidity premium and endogenous total ...

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 ...

Credit Misallocation and Macro Dynamics with Oligopolistic Financial Intermediaries
Bank market power shapes firm investment and financing dynamics and hence affects the transmission of macroeconomic shocks. Motivated by a secular increase in the concentration of the US banking industry, I study bank market power through the lens of a dynamic general equilibrium model with oligopolistic banks and heterogeneous firms. The lack of competition allows banks to price discriminate and charge firm-specific markups in excess of default premia. In turn, the cross-sectional dispersion of markups amplifies the impact of macroeconomic shocks. During a crisis, banks exploit their market ...

Exporting and Frictions in Input Markets : Evidence from Chinese Data
This paper investigates the impact of international trade on input market distortions. We focus on a specific friction, binding borrowing constraints in capital markets. We propose a theoretical model where a firm's demand for capital is constrained by an initial asset allocation and past sales. While the initial distribution of assets induces misallocation if the asset endowment at more productive firms does not fully cover their demand for capital, the dependence of the borrowing constraint from past sales proxies for cross-firm differences in the cost of default, which is empirically ...

Time Use and the Efficiency of Heterogeneous Markups
What are the welfare implications of markup heterogeneity across firms? In standard monopolistic competition models, such heterogeneity implies inefficiency even in the presence of free entry. We enrich the standard model with heterogeneous firms so that preferences are non-separable in off-market time and market consumption and show that this changes the welfare implications of markup heterogeneity. In this context, homogeneity of markups is neither necessary nor sufficient for efficiency. The marginal cost of the marginal firm is weakly inefficiently high when off-market time and market ...
