La evidencia empírica en la OCDE y España Author(s): Rubio Martín, Juan; Sánchez Pérez, César Abstract: Este artículo analiza el papel de la regulación en la liberalización de las telecomunicaciones fijas de banda ancha, con especial énfasis en los modelos aplicados en los países de la OCDE. Tras el análisis teórico y empírico de los casos más representativos a nivel internacional, la investigación propone una nueva orientación de la regulación. Las alternativas examinadas empíricamente son las siguientes: A) Adopción de un modelo de competencia dentro de una misma infraestructura, que requiere de una continua regulación ex ante (modelo de competencia en servicios o competencia intra-plataforma); B) Adopción de un modelo basado en competencia en infraestructuras (modelo de plena competencia en redes y servicios o competencia intra-plataformas). Las conclusiones y la evidencia empírica muestran la conveniencia de un modelo de competencia en infraestructuras (opción segunda), utilizando el análisis econométrico y el análisis cluster.

For that purpose, we use a longitudinal sample of Spanish manufacturing and services companies between 1983 and 2006, as well as OECD indicators on product market regulations. The productivity measurement is based on the control function approach, to overcome the endogeneity bias. Both for manufacturing and services firms, we have found that the share of temporary employment tends to reduce productivity, the effect being stronger for services firms, which make a more intensive use of this employment type. Our results also show that increases in competition lead to productivity improvements. Besides, those manufacturing firms who keep undertaking inhouse production of services tend to be more productive. The lack of competition in the services sector may be preventing firms to increase specialization while outsourcing nonmanufacturing activities Thu, 31 Dec 2009 23:00:00 GMT http://hdl.handle.net/10016/15736 2009-12-31T23:00:00Z http://hdl.handle.net/10016/15734 Title: Wage expectations for higher education students in Spain Author(s): Alonso-Borrego, César [alonso1]; Romero-Medina, Antonio [aromero] Abstract: We assess the ability of students to forecast future earnings, by using data on expected wages self-reported by college students with different graduation horizons. We find a signifficant gender effect, by which wages expectations are systematically lower for women than for men, this effect being different with different degree type in the case of junior students. However, the gender gap in actual wages exceeds the gender gap in wage expectations, suggesting that women do not fully account for the gender gap in their future earnings. Also, junior students with low college performance unrealistically predict higher expected wages. The comparison between students' wage expectations and actual wages for college graduates indicates that college students tend to over predict future wages, and overprediction is higher for women and for fresher students Sat, 30 Apr 2011 22:00:00 GMT http://hdl.handle.net/10016/15734 2011-04-30T22:00:00Z http://hdl.handle.net/10016/15707 Title: Corporate investment, irreversibilities and lumpiness : an empirical model Author(s): Alonso-Borrego, César [alonso1]; Sánchez Mangas, Rocío Abstract: We study the role of irreversibility and non convexities in firm investment decisions. For such purpose, we posit a dynamic structural investment model with irreversibility and nonconvex adjustment costs. We focus on the firm decision about whether to invest or not, which is characterized by means of a discrete choice dynamic programming problem. The adjustment cost parameters behind the investment decision are estimated with a longitudinal sample of Spanish manufacturing firms between 1990 and 2002. For these firms, we confirm that inaction and investment episodes account for a significant fraction of them. As estimation procedure, we apply the Nested Pseudo-Likelihood (NPL) algorithm by Aguirregabiria and Mira (2002). Thu, 14 Feb 2008 23:00:00 GMT http://hdl.handle.net/10016/15707 2008-02-14T23:00:00Z
