      Nonparametric estimation betas in the Market Model 

      Esteban González, María Victoria; Orbe Mandaluniz, Susan (2006)
      In this study an alternative nonparametric estimator to the Fama and MacBeth approach for the CAPM estimation is proposed. Betas and risk premiums are estimated simultaneously in order to increase the explanatory power of ...

      Nonparametric estimation of time varying parameters under shape restrictions 

      Orbe Mandaluniz, Susan; Ferreira García, María Eva; Rodríguez Poo, Juan M. (2001-01)
      In this paper we propose a new method to estimate nonparametrically a time varying parameter model when some qualitative information from outside data (e.g. seasonality) is available. In this framework we make two main ...

      Numerical Distribution Functions for Seasonal Unit Root Tests 

      Díaz-Emparanza Herrero, Ignacio (2011-12)
      When working with time series data observed at intervals smaller than a year, it is often necessary to test for the presence of seasonal unit roots. One of the most widely used methods for testing seasonal unit roots is ...

      On the strategic choice of spatial price policy: the role of the pricing game rules 

      Aguirre Pérez, Iñaki; Martín Arroyuelos, Ana María (2001-02)
      In this paper, whe show that the strategic choice of spatial price policy under duopoly crucially depends on the rules of price competition. Thisse and Vives (1988) show that spatial price discrimination is a dominant ...

      Output dynamics in an endogenous growth model 

      Barañano Mentxaka, Ilaski; Moral Zuazo, María Paz (2003-07)
      The aim of this paper is to analyze whether endogenous growth RBC models are consistent with two stylized facts about U.S. output dynamics. First, GNP growth is positively correlated in the short run and it has a weak ...

      Predicting Betas: Two new methods 

      Esteban González, María Victoria; Tusell Palmer, Fernando Jorge (2009)
      Betas play a central role in modern finance. The estimation of betas from historical data and their extrapolation into the future is of considerable practical interest. We propose two new methods: the first is a direct ...

      Product Differentiation with Consumer Arbitrage 

      Aguirre Pérez, Iñaki; Espinosa Alejos, María Paz (2003-03)
      We analyze the consequences of consumers behavior concerning personal arbitrage in a spatial discrimination context where firms know the consumers distribution but cannot distinguish them by location. The firms' equilibrium ...

      Quesnay and Leontief on Capital and Income 

      Ormazabal Sánchez, Kepa Mirena (2002-03)
      I analyze Quesnay's explanation of the "Tableau Economique" of 1766 in order to show that he made a clear distinction between capital and income. In holding this distinction, Quesnay rejected the nowadays currently accepted ...
