In an economy with one riskless and one risky asset, we compare the Sharpe ratios of investment funds that allow: i) timing strategies which forecast the market using simple regressions; ii) a strategy which uses multiple regression instead; and iii) a passive allocation which combines the funds in...

We provide numerically reliable analytical expressions for the score of conditionally heteroskedastic dynamic regression models when the conditional distribution is multivariate t. We also derive one-sided and two-sided LM tests for multivariate normality versus multivariate t based on the first...

This paper investigates the influence of individual characteristics and the business cycle on the probability of entry into self-employment and on self-employment duration. We estimate multinomial logit and discrete competing risks models using data from a longitudinal sample of Spanish men for...

The purpose of this paper is to formulate procedures for the analysis of the time series behaviour of micro panel data subject to censoring. We assume an autoregressive model with random effects for a latent variable which is only partly observed due to a selection mechanism. Our methods are...

This chapter focuses on two of the developments in panel data econometrics since the Handbook chapter by Chamberlain (1984). The first objective of this chapter is to provide a review of linear panel data models with predetermined variables. We discuss the implications of assuming that...

This paper tests a traditional model of asset pricing, the CCAPM (Consumption Capital Asset Pricing Model), using data from the Spanish stock market. A generalized calibration method is used to test this model. This method allows us to judge the degree of correspondance between the population...

This paper considers a model of firms' financing based on the existence of a moral hazard problem in the choice of investment projects by a heterogeneous population of entrepreneurs. Two alternative ways of funding these projects, called unmonitored (or market) and monitored (or bank) lending,...
