This paper develops a uniform test of linearity against thresholds effects in the quantile regression framework. The test is based on the supremum of the Wald process over the space of quantile and threshold parameters. We establish the asymptotic null distribution of the test statistic for stationary weakly dependent processes, and propose a simulation(More)
We study the impact of university-industry research collaborations on academic output, in terms of productivity and direction of research. We report findings from a longitudinal dataset on all the researchers from the engineering departments in the UK in the last 20 years. We control for the endogeneity caused by the dynamic nature of research and the(More)
This paper develops an instrumental variables estimator for quantile regression in panel data with fixed effects. Asymptotic properties of the instrumental variables estimator are studied for large N and T when Na/T → 0, for some a > 0. Wald and Kolmogorov-Smirnov type tests for general linear restrictions are developed. The estimator is applied to the(More)
This paper studies panel quantile regression models with fixed effects. We formally establish sufficient conditions for consistency and asymptotic normality of the quantile regression estimator when the number of individuals, n, and the number of time periods, T , jointly go to infinity. The estimator is shown to be consistent under similar conditions to(More)
This paper studies the connections among quantile regression, the asymmetric Laplace distribution, maximum likelihood and maximum entropy. We show that the maximum likelihood problem is equivalent to the solution of a maximum entropy problem where we impose moment constraints given by the joint consideration of the mean and median. Using the resulting score(More)
This paper studies the link between migration, remittances and productive assets accumulation for a panel of poor rural households in Mexico over the period 19972006. In a context of financial markets imperfections, migration may act as a substitute for imperfect credit and insurance provision (through remittances from migrants) and, thus, exert a positive(More)
This paper empirically explores the effect of bank lending relationships in the interbank market. We use data from the e-MID market that represents the only transparent electronic platform in Europe and USA, unaffected by search costs and other fictions. We show that stable relationships exist and that they played a significant role during the 2007–2008(More)
In this paper, we develop a reduced form multivariate quantile model, using a directional quantile framework. The proposed model is the solution to a collection of directional quantile models for a fixed orthonormal basis, in which each component represents a directional quantile that corresponds to a particular endogenous variable. The model thus delivers(More)
