Patent citations are extensively used as a measure of patent quality. However, counting citations does not account for the fact that citations come from patents of different qualities, and that citations are of variable qualities. We develop a citation index which takes into account the...

We analyze the degree of persistence of the unemployment rates of the 10 Canadian provinces using quarterly data for the period 1976:1-2005:4. We apply a two-break minimum Lagrange Multiplier unit root statistic, which, unlike standard unit root statistics (without or with breaks), makes it...

Using Markov-Switching models, this paper studies the existence of a relationship between the unemployment rate and four different types of crimes in the U.S. economy. After it, using the non-parametric Concordance Index of Harding and Pagan (2002, 2006), the correlation between the cycles of...

Purpose – Based on the approach of Timljonavich and Vogelsang, the purpose of this paper is to present empirical evidence of the role of the federal transfers on the ß-convergence process in Canadian provinces. Design/methodology/approach – The paper uses information on annual personal...

El presente documento analiza el impacto de las expectativas políticas (medida como la probabilidad de que un candidato gane las elecciones) sobre los retornos del índice general de la Bolsa de Valores de Lima (IGBVL) utilizando información para los períodos electorales de 1995 y 2000. La...

Siguiendo el trabajo de Favero y Rovelli (2003), estimamos un sistema de 3 ecuaciones para diferentes muestras de la economía Peruana con el objetivo de analizar la evolución de los parámetros asociados a las preferencias de la autoridad monetaria y a la estructura de la economía. Los...

Following Elliott (1999; International Economic Review 40, 767--83.) and Perron and Rodríguez (2003; Journal of Econometrics 115,1--27), we develop unit root tests in the context of structural change models using GLS detrended data ( Elliott, Rothenberg and Stock 1996; Econometrica 64, 813--39) when the...

Flexible exchange rate experience in Peru has been accompanied by frequent official interventions in the form of foreign exchange purchases or sales. Monetary authority pursues reducing excess volatility in the exchange rate through its direct intervention. However, in recent years, this...

This paper identifies the output gap using the theoretical definition of the gap within a Phillips curve. The results show that the output gap is large and persistent. Furthermore, the output gap is not correlated with the stochastic trend which is similar to the asumption used in the unobserved...

Using di¤erent unit root statistics and the approach of Tomljanovich and Vogelsang (2002), we test for the existence of stochastic and beta-convergence in the unemployment rates of a set of thirteen European countries. Using quarterly data for the period 1984:1-2005:4, we observe that there has...
