I appreciate the clarification of my work by Tan and Wright, regret the confusing way my equations were labeled, and intended them to be interpreted in the manner they suggest is correct.
To account for the uneven distribution of economic activity in space, I propose a theory of the location choices of heterogeneous firms in a variety of sectors across cities. In equilibrium, the distribution of city sizes and the sorting patterns of firms are uniquely determined and affect aggregate TFP and welfare. I estimate the model using French firm-level data and find that nearly half of the productivity advantage of large cities is due to firm sorting, the rest coming from agglomeration economies. I quantify the general equilibrium effects of place-based policies: policies that subsidize smaller cities have negative aggregate effects.
The entry and exit of products, rather than firms, serve as the main equilibrating force in many markets, so accurately predicting changes from a merger or bankruptcy should incorporate this behavior. This paper estimates a structural model of the US commercial vehicle market and demonstrates the importance of allowing for endogenous product offerings in the context of the $85 billion automotive industry bailout in 2009. Under alternate policies that facilitate an acquisition or liquidation of GM and Chrysler, product entry and exit moderate markup increases and output decreases by up to three-quarters.
Before filing suit, a plaintiff can take a financial position in a defendant firm. A short position benefits the plaintiff by transforming a negative expected-value claim into a positive expected-value one and by enhancing the claim's settlement value. If the capital market is less than strong-form efficient, the plaintiff also benefits directly from the decline in the defendant's stock price. When the defendant is privately informed about the case's merits, bargaining failures can arise. While aggressive short-selling benefits the plaintiff at the expense of the defendant, moderate levels of short-selling can benefit the defendant and raise the settlement rate.
A salient characteristic of sovereign defaults is that they are typically accompanied by large devaluations. This paper presents new evidence of this empirical regularity known as the Twin Ds and proposes a model that rationalizes it as an optimal policy outcome. The model combines limited enforcement of debt contracts and downward nominal wage rigidity. Under optimal policy, default is shown to occur during contractions. The role of default is to free up resources for domestic absorption, and the role of exchange rate devaluation is to lower the real value of wages, thereby reducing involuntary unemployment.
This paper studies the business-cycle dynamics of secondary markets for physical capital and their effects on the macroeconomy. In the data, both capital reallocation and the price of used capital are procyclical. To rationalize these facts, I propose a model with endogenous partial irreversibility, where used investment goods are imperfect substitutes for new ones because of firm-level capital specificity. Equilibrium dynamics in the market for used capital induce countercyclical dispersion of marginal products of capital, propagate movements in aggregate TFP, and provide a microfoundation for state-dependent nonconvex capital adjustment costs.
A large and growing literature has documented the importance of peer effects in education. However, there is relatively little evidence on the long-run educational and labor market consequences of childhood peers. We examine this question by linking administrative data on elementary school students to subsequent test scores, college attendance and completion, and earnings. To distinguish the effect of peers from confounding factors, we exploit the population variation in the proportion of children from families linked to domestic violence, who have been shown to disrupt contemporaneous behavior and learning. Results show that exposure to a disruptive peer in classes of 25 during elementary school reduces earnings at age 24 to 28 by 3 percent. We estimate that differential exposure to children linked to domestic violence explains 5 percent of the rich-poor earnings gap in our data, and that each year of exposure to a disruptive peer reduces the present discounted value of classmates’ future earnings by $80,000.
We provide a theory of rational stock price bubbles in production economies with infinitely-lived agents. Firms meet stochastic investment opportunities and face endogenous credit constraints. They are not fully committed to repaying debt. Credit constraints are derived from incentive constraints in optimal contracts which ensure default never occurs in equilibrium. Stock price bubbles can emerge through a positive feedback loop mechanism and cannot be ruled out by transversality conditions. These bubbles command a liquidity premium and raise investment by raising the debt limit. Their collapse leads to a recession and a stock market crash.
We investigate the link between real exchange rates and sectoral TFP for eurozone countries. We show that real exchange rate variation, both cross-country and time-series, closely accords with an amended Balassa-Samuelson interpretation, incorporating sectoral productivity shocks and a labor market wedge. We construct a DSGE model to generate a cross section and time series of real exchange rates to compare to data. Estimates from simulated regressions are very similar to estimates for eurozone data. Our findings contrast with previous studies that have found little relationship between productivity and real exchange rates among high-income countries that have floating nominal exchange rates.
This paper estimates the incidence of corporate taxes on wages using a 20-year panel of German municipalities exploiting 6,800 tax changes for identification. Using event study designs and difference-in-differences models, we find that workers bear about one-half of the total tax burden. Administrative linked employer-employee data allow us to estimate heterogeneous firm and worker effects. Our findings highlight the importance of labor market institutions and profit-shifting opportunities for the incidence of corporate taxes on wages. Moreover, we show that low-skilled, young, and female employees bear a larger share of the tax burden. This has important distributive implications.
