Our novel approach to modeling monopolistic competition with heterogeneous consumers involves a space of characteristics of a differentiated good (consumers' ideal points), alike Hotelling (1929). Firms have heterogeneous costs à la Melitz (2003). In addition to price setting, each firm also...

Our novel approach to modeling monopolistic competition with heterogeneous firms and consumers involves spatial product differentiation. Space can be interpreted either as a geographical space or as a space of characteristics of a differentiated good. In addition to price setting, each firm also...

This paper is concerned with cross-dependencies between endogenous market structure and tax policy. We extend the Mirrlees (1971) model of income taxation with a monopolistic competition framework with general additively separable consumer preferences. We show that price and variety distortions...

We consider a model of monopolistic competition with several heterogeneous sectors and endogenous labor supply. For low (high) values of the labor supply elasticity, we show that there is always a unique equilibrium. For medium values of the labor supply elasticity, the set of equilibria (if...

Trade credit is the most important form of short-term finance for firms. In 2019, U.S. nonfinancial firms had about $4.5 trillion in trade credit outstanding equaling 21 percent of U.S. GDP. This paper documents two striking facts about trade credit use. First, firms with higher markups supply...

Most domestic and international firm-to-firm transactions rely on trade credit, where sellers grant buyers time to pay the invoice after delivery. Exploiting Chilean and Colombian transaction-level trade data, this paper documents new facts about trade credit use: trade credit use increases with...

Using a unique confidential data set with industry disaggregation of official U.S. claims and liabilities, we find that dollar-denominated securities are increasingly inter-mediated by tax havens financial centers (THFC) and by less regulated funds. These securities are risky and respond to tax...

We challenge the common practice of estimating gravity equations with time-interval data in order to capture dynamic-adjustment effects to trade-policy changes. Instead, we point to a series of advantages of using consecutive-year data recognizing dynamic-adjustment effects. Our analysis reveals...

In this paper, employing transaction level data for Russian imports, we explore the role of multi-product shipments in explaining shipping patterns across countries. First, we document that firms from more developed countries include on average more different products into a single shipment. We...

We show that U.S. dollar movements affect syndicated loan terms for U.S. borrowers, even for those without trade exposure. We identify the effect of dollar movements using spread and loan amount adjustments during the syndication process. Using this high-frequency, within loan variation, we find...
