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...

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...

We propose a simple and flexible econometric approach to quantify ex-ante the “deep” impact of trade liberalization and the “hard” effects of protection with the empirical structural gravity model. Specifically, we argue that the difference between the estimates of border indicator...

We propose new methods to identify the full impact of country-specific characteristics on bilateral trade flows within the framework of ‘the new quantitative trade model.’ We complement theory with a simple two-stage estimating procedure, and offer a proof of concept by quantifying the...

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...

This paper introduces the third update/release of the Global Sanctions Data Base (GSDB-R3). The GSDB-R3 extends the period of coverage from 1950-2019 to 1950-2022, which includes two special periods – COVID-19 and the war between Russia and Ukraine. The new update of the GSDB contains a total...

This paper uses a new dataset on the universe of Canadian imports and tariffs between 1924 and 1936, disaggregated into 1697 goods originating in 112 countries, to analyse the impact on Canadian imports of interwar Canadian trade policy, including the 1932 Ottawa trade agreements. Rather than...
