      In two recent cases involving the University of Michigan, the Supreme Court examined whether race should be allowed to play an explicit role in the admission decisions of schools. The primary argument in these court cases ...
    • Career concerns: a human capital perspective 

      Camargo, Bráz Ministério de; Pastorino, Elena
      2012-09-12
      We introduce human capital accumulation, in the form of learning by doing, in a life cycle model of career concerns and analyze how human capital acquisition a ects implicit incentives for performance. We show that standard ...
    • The essentiality of money in environments with centralized trade 

      Araújo, Luís; Camargo, Bráz Ministério de; Minetti, Raoul; Puzzello, Daniela
      2012
      Lagos and Wright (2005) introduced an influential model of monetary exchange in which trade alternates between centralized and decentralized markets and money is essential. A limitation of their model and of the literature ...
    • Information learning and the stability of fiat money 

      Araujo, Luis Fernando Oliveira de; Camargo, Bráz Ministério de
      2004-08
      We analyze the stability of monetary regimes in a decentralized economy where fiat money is endogenously created, information about its value is imperfect, and agents only learn from their personal trading experiences. We ...
    • Information Spillovers, Gains from Trade, and Interventions in Frozen Markets 

      Camargo, Bráz Ministério de; Kim, Kyungmin; Lester, Benjamin
      2016
      We study government interventions in markets suffering from adverse selection. Importantly, asymmetric information prevents both the realization of gains from trade and the production of information that is valuable to ...
    • Information, market incentives, and student performance: Evidence from a regression discontinuity design in Brazil 

      Camargo, Bráz Ministério de; Camelo, Rafael de Sousa; Firpo, Sergio Pinheiro; Ponczek, Vladimir Pinheiro
      2018
      We use a discontinuity on the test score disclosure rule for the National Secondary Education Examination in Brazil to test whether test score disclosure affects student performance in public and private schools. We find ...
    • Interracial friendships in college 

      Camargo, Bráz Ministério de; Stinebrickner, Ralph; Stinebrickner, Todd
      2010-10
      We use unique longitudinal data to provide direct evidence about interracial friendships at different stages of college and to provide new evidence about some of the reasons for the observed patterns of interaction. We ...
    • Learning in society 

      Camargo, Bráz Ministério de
      2014
      In an individual experimentation problem a decision maker learns only from his own experience. It is well known that an optimal experimentation strategy for such problems sometimes results in the best alternative being ...
    • Learning-by-employing: the value of commitment 

      Camargo, Bráz Ministério de; Pastorino, Elena
      2010-06-24
      We analyze a dynamic principal–agent model where an infinitely-lived principal faces a sequence of finitely-lived agents who differ in their ability to produce output. The ability of an agent is initially unknown to both ...
    • Learning-by-employing: the value of commitment under uncertainty 

      Camargo, Bráz Ministério de; Pastorino, Elena
      2016-07
      We analyze commitment to employment in an environment in which an infinitely lived firm faces a sequence of finitely lived workers who differ in their ability. A worker's ability is initially unknown, and a worker's effort ...
    • Limited memory and the essentiality of money 

      Araujo, Luis Fernando Oliveira de; Camargo, Bráz Ministério de
      2010-06-25
      This paper investigates the relationship between memory and the essentiality of money. We consider a random matching economy with a large finite population in which commitment is not possible and memory is limited in the ...
    • Limited monitoring and the essentiality of money 

      Araujo, Luis Fernando Oliveira de; Camargo, Bráz Ministério de
      2015-05
      Monetary theory emphasizes that imperfect monitoring is necessary for money to be essential, that is, for money to achieve socially desirable allocations. Little is known about how limited monitoring must be if money is ...
    • Monetary equilibrium with decentralized trade and learning 

      Araujo, Luis Fernando Oliveira de; Camargo, Bráz Ministério de
      2010-06-25
      This paper analyzes the stability of monetary regimes in an economy where fiat money is endogenously created by the government, information about its value is imperfect, and learning is decentralized. We show that monetary ...
    • Money versus memory 

      Araujo, Luis Fernando Oliveira de; Camargo, Bráz Ministério de
      2010-06-25
      A well–established fact in monetary theory is that a key ingredient for the essentiality of money is its role as a form of memory. In this paper we study a notion of memory that includes information about an agent’s past ...
    • On the origins of monetary exchange 

      Araujo, Luis Fernando Oliveira de; Bignon, Vincent; Breton, Régis; Camargo, Bráz Ministério de

      2012-09-12
      In this paper we test whether the disclosure of test scores has direct impacts on student performance, school composition and school inputs. We take advantage of the discontinuity on the disclosure rules of The National ...
    • Trading dynamics in decentralized markets with adverse selection 

      Camargo, Bráz Ministério de; Lester, Benjamin
      2014-09
      We study a dynamic, decentralized lemons market with one-time entry and characterize its set of equilibria. Our framework offers a theory of how 'frozen' markets suffering from adverse selection recover or 'thaw' over time ...
