This work proposes novel network analysis techniques for multivariate time series. We define the network of a multivariate time series as a graph where vertices denote the components of the process and edges denote non zero long run partial correlations. We then introduce a two step LASSO...

We present an exact test for whether two random variables that have known bounds on their support are negatively correlated. The alternative hypothesis is that they are not negatively correlated. No assumptions are made on the underlying distributions. We show by example that the Spearman rank...

In order to have references for discussing mathematical menus in political science, I review the most common types of mathematical formulae used in physics and chemistry, as well as some mathematical advances in economics. Several issues appear relevant: variables should be well defined and...

Much of empirical economics involves regression analysis. However, does the presentation of results affect economists’ ability to make inferences for decision making purposes? In a survey, 257 academic economists were asked to make probabilistic inferences on the basis of the outputs of a...

We investigate macroeconomic fluctuations in the Mediterranean basin, their similarities and convergence. A model with four indicators, roughly covering the West, the East and the Middle East and the North Africa portions of the Mediterranean, characterizes well the historical experience since...

Youth is one of the phases in the life-cycle when some of the most decisive life transitions take place. Entering the labour market or leaving parental home are events with important consequences for the economic well-being of young adults. In this paper, the interrelationship between...

In this paper we analyse the observed systematic differences in costs for teaching hospitals (THhenceforth) in Spain. Concern has been voiced regarding the existence of a bias in the financing of TH’s has been raised once prospective budgets are in the arena for hospital finance, and claims...

This paper studies the apparent contradiction between two strands of the literature on the effects of financial intermediation on economic activity. On the one hand, the empirical growth literature finds a positive effect of financial depth as measured by, for instance, private domestic credit...

This paper analyzes collective bargaining using Spanish firm level data. Central to the analysis are the joint determination of wage and strike outcomes in a dynamic framework and the possibility of segregate wage equation for strike and non-strike outcomes. Conditional to strikes taking place,...

In this paper I show how borrowing constraints and job search interact. I fit a dynamic model to data from the National Longitudinal Survey (1979-cohort) and show that borrowing constraints are significant. Agents with more initial assets and more access to credit attain higher wages for several...
