The effect of website provision on the demand for German women's magazines is analyzed using differentiated product demand models estimated on panel data that cover the period 1990 2000. Descriptive evidence on the magazines' website contents suggests that websites are used to provide...

Researchers interested in estimating productivity can choose from an array of methodologies, each with its strengths and weaknesses. Methods differ by the assumptions they rely on and imply very different calculations. I compare five widely used techniques: (a) index numbers, (b) data...

The main objective of this paper is to elucidate the capability of time-series regression models to capture and forecast movements in occupancy patterns, rental rates and construction activity. The model presented is a three-stage simultaneous equation model. The first stage incorporates the...

Grandmont (1985) found that the parameter space of the most classical dynamic models are stratified into an infinite number of subsets supporting an infinite number of different kinds of dynamics, from monotonic stability at one extreme to chaos at the other extreme, and with all forms of...

The purpose of this paper is to test the (rational) expectations hypothesis of the term structure of interest rates using Portuguese data for the interbank money market. The results obtained support only a very weak, long-run or "asymptotic" version of the hypothesis, and broadly agree with...

This paper determines the causal link between FDI and corruption in 42 developing countries using linear and non linear panel Granger causal methods over the period 1998 to 2009. The findings show that the outcome of the causal association depends on the method used. The linear panel methods...

This study investigates the long-run relationship between natural gas prices and stock prices by using the Johansen and Juselius cointegration test and error–correction based Granger causality models for the EU-15 countries. We employ quarterly data covering the period from 1990:1 to 2008:1....

Social capital can be defined as the capacity of individuals or groups to obtain benefits by participating in social networks (Robinson, Siles and Schmid and, Flores and Rello in Atria and Siles eds. 2003). In this paper, we use data from the second round of the Panel of Low Income Households in...

Stationary I(0) models employed in yield curve analysis typically imply an unrealistically low degree of volatility in long-run short-rate expectations due to fast mean reversion. In this paper we propose a novel multivariate affine term structure model with a two-fold source of persistence in...

In the wake of the subprime crisis of 2007 which uncovered shortfalls in capital levels of most financial institutions, the Basel Committee planned to strengthen current regulations contained in Basel II. While maintaining the Internal Model Approach based on Value-at-Risk, a stressed VaR...
