This paper proposes a mechanism that can be operated without money in situations where agents have to decide over some common projects when they are not informed about others' preferences. The success of the mechanisms proposed in the literature to deal with similar problems usually relies on...

This paper identifies structural breaks in the post-World War II joint dynamics of U.S. inflation, unemployment and the short-term interest rate. We derive a structural break-date procedure which allows for long-memory behavior in all three series and perform the analysis for alternative data...

The interpretation of the Fama and French (1993) SMB and HML factors as risk factors is an open question that has carried a lot of controversy in the asset pricing literature and it is far from being solved. The aim of this study is to contribute to the understanding of this issue by analyzing a...

This paper analyzes the impact of the exchange rate volatility on the performance of the Peruvian economy using financial information from 163 non-financial listed firms. We find evidence that, for firms holding dollar-denominated debt, investment decisions are negatively affected by real...

We propose in this article a two-step testing procedure of fractional cointegration in macroeconomic time series. It is based on Robinson’s (1994) univariate tests and is similar in spirit to the one proposed by Engle and Granger (1987), testing initially the order of integration of the...

A new automatic method based on the wavelet and Hilbert transforms for measuring the motor unit action potential (MUAP) duration is presented in this work. A total of 182 MUAPs from two different muscles were analysed. The average MUAP waveform was wavelet-transfomed, and a particular scale of...

A semiparametric bivariate fractionally cointegrated system is considered, integration orders possibly being unknown and I(0) unobservable inputs having nonparametric spectral density. Two kinds of estimate of the cointegrating parameter ν are considered, one involving inverse spectral...

In this paper we review the factors that may lead to structural changes in stock market volatility and present an analysis that assesses whether Spanish stock market volatility has changed significantly over the period 1941-2001. This period corresponds to the years of more profound development...

The classical Allingham-Sandmo-Yitzhaki model explains tax evasion behavior based on the probability of being discovered, the amount of the fine imposed and the level of risk aversion. Nonetheless, empirical studies show that the decision and the level of tax evasion depends also on non economic...

Economic theories in dynamic contexts usually impose certain restrictions on the conditional mean of the underlying economic variables. Omnibus specification tests are the primary tools to test such restrictions when there is no information on the possible alternative. In this paper we study in...
