Using daily observations of the index and stock market returns for the Peruvian case from January 3, 1990 to May 31, 2013, this paper models the distribution of daily loss probability, estimates maximum quantiles and tail probabilities of this distribution, and models the extremes through a...

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...

This note analyzes the empirical size of the augmented Dickey and Fuller (ADF) statistic proposed by Perron and Rodríguez (2003) when the errors are fractional. This ADF is based on a searching procedure for additive outliers based on first-differences of the data named td. Simulations show...

The increasing penetration of electricity generation from renewable energy is posing new technical challenges to the operation of power systems. Some of them are related to the different electrical behavior of the generators when compared with traditional directly coupled synchronous generators....

In this paper, we analyze the impact of several labor reforms in Spain on its equilibrium unemployment rate. To this end, we analyzed the behavior of the observed unemployment rate in Spain during the 1976-2012 period, thereby assessing whether that rate is better characterized as a hysteresis...

The increasing penetration of wind energy into power systems has pushed grid operators to set new requirements for this kind of generating plants in order to keep acceptable and reliable operation of the system. In addition to the low voltage ride through capability, wind farms are required to...
