Abstract We study both theoretically and empirically the relationship between different types of corporate social responsibility (CSR) and a firm’s product quality. On the one hand, observable external CSR (e.g., a firm’s involvement in a social project) can be used as a signal to unobservable product quality. On the other hand, internal CSR (e.g., human…

Abstract It is well known that exporter firms pay higher wages and are more skill intensive than domestic firms. In this paper we measure and decompose the exporter wage gap into several explanatory components by estimating counterfactual distributions for the Spanish manufacturing sector between 1995 and 2010. We find that conditional wages are more compressed…
Abstract Two major classes of preference elicitation methods are Matching and Choice. In Matching Methods, respondents are asked to establish indifference between two options.

We study if there are elicitation methods that reduce or eliminate this discrepancy between Matching…

The absolute gap between OECD and the Rest widened over time, but…
Abstract This paper introduces a novel semi-nonparametric (SNP) distribution that we name Expansion of Moments (ME hereafter). The innovation of this density lies in its polynomials given by the difference between the n-th power of the variable and the n-th moment of the parametric density used as basis. We show that the ME keeps the…

Based on the intra-day realized volatility and the organization of the market, volatility can only be transmitted from session 1 to 6 in chronological order, which allows formulate six Autoregressive Distributed…
