    • Dynamic Olley-Pakes Productivity Decomposition with Entry and Exit 

      Melitz, Marc J.; Polanec, Sašo (Wiley-Blackwell, 2015)
      In this paper, we propose an extension of the productivity decomposition method developed by Olley & Pakes (1996). This extension provides an accounting for the contributions of both firm entry and exit to aggregate ...
    • Endogenous Entry, Product Variety, and Business Cycles 

      Bilbiie, Florin O.; Ghironi, Fabio; Melitz, Marc J. (The University of Chicago Press, 2012)
      This paper builds a framework for the analysis of macroeconomic fluctuations that incorporates the endogenous determination of the number of producers and products over the business cycle. Economic expansions induce higher ...
    • Essays in Economic Geography 

      Ziv, Oren (2015-05-18)
      While economic geography is concerned chiefly with proximity, models in urban economics eliminate proximity as a relative metric in order to preserve tractability. I introduce a new method of solving spatial models that ...
    • Essays in International Trade and Development 

      Dragusanu, Raluca Ecaterina (2014-06-06)
      This dissertation studies different aspects of the interaction between developed and developing countries in global supply chains. The first chapter studies the matching between importing and exporting firms in global ...
    • Essays in Macroeconomics 

      Baqaee, David Rezza (2015-04-20)
      This dissertation focuses on three prominent areas of macroeconomic policy: fiscal stimulus, bail-outs and industrial policy, and monetary policy. In each case, I analyze the nature of the problem without intervention first ...

      Du, Yang (2016-05-18)
      This dissertation consists of three essays, two in the field of international economics and one in macroeconomics. The first essay studies the interaction of manufacturing firms' sourcing decisions and their R\&D investment. ...
    • Estimating Trade Flows: Trading Partners and Trading Volumes 

      Helpman, Elhanan; Melitz, Marc; Rubinstein, Yona (MIT Press, 2008)
      We develop a simple model of international trade with heterogeneous firms that is consistent with a number of stylized features of the data. In particular, the model predicts positive as well as zero trade flows across ...
    • Export versus FDI with Heterogeneous Firms 

      Helpman, Elhanan; Melitz, Marc; Yeaple, Stephen (American Economic Association, 2004)
    • Gains from Trade When Firms Matter 

      Melitz, Marc J.; Trefler, Daniel (American Economic Association, 2012)
      The rising prominence of intra-industry trade and huge multinationals has transformed the way economists think about the gains from trade. In the past, we focused on gains that stemmed either from endowment differences ...
    • International Trade and Macroeconomic Dynamics with Heterogeneous Firms 

      Ghironi, Fabio; Melitz, Marc (MIT Press, 2005)
      We develop a stochastic, general equilibrium, two-country model of trade and macroeconomic dynamics. Productivity differs across individual, monopolistically competitive firms in each country. Firms face a sunk entry cost ...
    • A Many-Country, Many-Good Model of Labor Market Rigidities as a Source of Comparative Advantage 

      Cuñat, Alejandro; Melitz, Marc J. (John Wiley & Sons Ltd., 2009)
      We extend the theoretical framework in Cuñat and Melitz (2007) to a many-country setup where countries exhibit different degrees of labor market fexibility. We rely on the insights from a recent paper by Costinot (2009) ...
    • Market Size, Competition, and the Product Mix of Exporters 

      Mayer, Thierry; Melitz, Marc J.; Ottaviano, Gianmarco I. P. (American Economic Association, 2014)
      We build a theoretical model of multi-product firms that highlights how competition across market destinations affects both a firm's exported product range and product mix. We show how tougher competition in an export ...
    • Market Size, Trade, and Productivity 

      Melitz, Marc; Ottaviano, Gianmarco (Wiley-Blackwell, 2008)
      We develop a monopolistically competitive model of trade with firm heterogeneity—in terms of productivity differences—and endogenous differences in the "toughness" of competition across markets—in terms of the number and ...
    • Missing Gains from Trade? 

      Melitz, Marc J.; Redding, Stephen J. (American Economic Association, 2014)
      The theoretical result that there are welfare gains from trade is a central tenet of international economics. In a class of trade models that satisfy a gravity equation, the welfare gains from tradecan be computed ...
    • New Trade Models, New Welfare Implications 

      Melitz, Marc J.; Redding, Stephen J. (American Economic Association, 2015)
      We show that endogenous firm selection provides a new welfare margin for heterogeneous firm models of trade (relative to homogeneous firm models). Under some parameter restrictions, the trade elasticity is constant and is ...
    • Pecuniary Externalities in Labor Markets and Questions in Macroeconomics and International Trade 

      Schwarz, Lukas Marinus (2016-04-21)
      I analyze how various types of structural change including labor market reform, trade liberalization, product market reform and technological progress affect labor markets in closed and open economies. In order to do this, ...
    • Trade Flow Dynamics with Heterogeneous Firms 

      Ghironi, Fabio; Melitz, Marc (American Economic Association, 2007)
      We use a two-country, stochastic, general equilibrium model of international trade and macroeconomic dynamics with monopolistic competition and heterogeneous firms to explore the role of entry in the domestic economy and ...
    • Trade Liberalization and Firm Dynamics 

      Melitz, Marc J.; Burstein, Ariel (Cambridge University Press, 2013)
      In this paper, we analyze the transition dynamics associated with an economy's response to trade liberalization. We start by reviewing the recent literature that incorporates firm dynamics into models of international ...
    • Volatility, Labor Market Flexibility, and the Pattern of Comparative Advantage 

      Cuñat, Alejandro; Melitz, Marc J. (Wiley Blackwell (Blackwell Publishing), 2012)
      This paper studies the link between volatility, labor market flexibility, and international trade. International differences in labor market regulations affect how firms can adjust to idiosyncratic shocks. These institutional ...
    • When and How Should Infant Industries Be Protected? 

      Melitz, Marc (Elsevier Science B.V., 2005)
      This paper develops and analyzes a welfare maximizing model of infant industry protection. The domestic infant industry is competitive and experiences dynamic learning effects that are external to firms. The competitive ...
