      Dixit, Avinash; Grossman, Gene M.; Helpman, Elhanan (University of Chicago Press, 1997)
      We develop a model of common agency with complete information and general preferences with nontransferable utility, and we prove that the principals' Nash equilibrium in truthful strategies implements an efficient action. ...

    • Competing for Endorsements 

      Grossman, Gene M; Helpman, Elhanan (1998-05)

    • Dynamics of a Floating Exchange Rate Regime 

      Helpman, Elhanan; Razin, Assaf (University of Chicago Press, 1982)
      We study the full equilibrium dynamics of a two-country world economy with a floating exchange rate, traded and nontraded goods, and explicit modeling of the use of money. The resulting exchange rate equation depends on ...

    • 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 on the Transmission and Diffusion of Productive Knowledge in International Economics 

      Bahar, Dany (2014-06-06)
      Numerous empirical studies have shown the difficulties associated with the transmission of knowledge and the limitations of its diffusion process. What are the implications of these difficulties and limitations to international ...

    • 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 ...

    • An Exploration in the Theory of Exchange-Rate Regimes 

      Helpman, Elhanan (University of Chicago Press, 1981)
      Three exchange-rate regimes--a float, a one-sided peg, and a cooperative peg--are evaluated and compared in terms of efficiency and welfare levels. The framework of analysis embodies country-specific monies, with the money ...

    • Global Sourcing 

      Antras, Pol; Helpman, Elhanan (University of Chicago Press, 2004)
      We present a North‐South model of international trade in which differentiated products are developed in the North. Sectors are populated by final‐good producers who differ in productivity levels. On the basis of productivity ...

    • Growth, Trade, and Inequality 

      Grossman, Gene; Helpman, Elhanan (2014)
      We introduce firm and worker heterogeneity into a model of innovation-driven endogenous growth. Individuals who differ in ability sort into either a research sector or a manufacturing sector that produces differentiated ...

    • Income Distribution, Product Quality, and International Trade 

      Fajgelbaum, Pablo; Grossman, Gene; Helpman, Elhanan (University of Chicago Press, 2011)
      We develop a framework for studying trade in vertically and horizontally differentiated products. In our model, consumers with heterogeneous incomes and tastes purchase a homogeneous good as well as making a discrete choice ...

    • Inequality and Unemployment in a Global Economy 

      Helpman, Elhanan; Itskhoki, Oleg; Redding, Stephen (Econometric Society, 2010)
      This paper develops a new framework for examining the determinants of wage distributions that emphasizes within-industry reallocation, labor market frictions, and differences in workforce composition across firms. More ...

    • Labour Market Rigidities, Trade and Unemployment 

      Helpman, Elhanan; Itskhoki, Oleg (Oxford University Press (OUP), 2010)
      We study a two-country two-sector model of international trade in which one sector produces homogeneous products while the other produces differentiated products. The differentiated-product industry has firm heterogeneity, ...

    • Matching, Sorting, and the Distributional Effects of International Trade 

      Grossman, Gene; Helpman, Elhanan; Kircher, Philipp (University of Chicago Press, 2017)
      We study the distributional consequences of trade in a world with two industries and two heterogeneous factors of production. Productivity in each production unit reflects the ability of the manager and the abilities of ...

    • Negotiating Free Trade 

      Aghion, Philippe; Antras, Pol; Helpman, Elhanan (Elsevier, 2007)

    • Outsourcing in a Global Economy 

      Grossman, Gene M.; Helpman, Elhanan (Oxford University Press (OUP), 2005)
      We study the determinants of the location of sub-contracted activity in a general equilibrium model of outsourcing and trade. We model outsourcing as an activity that requires search for a partner and relationship-specific ...

    • Pecuniary Externalities in Labor Markets and Questions in Macroeconomics and International Trade 

      Schwarz, Lukas Marinus (2016-04-21)
