Using one of the key property of copulas that they remain invariant under an arbitrary monotonous change of variable, we investigate the null hypothesis that the dependence between financial assets can be modeled by the Gaussian copula. We find that most pairs of currencies and pairs of major...

The aim of this paper is to provide evidence about the existence or non- existence of structural breaks in exchange rates of European transition economies. We used the testing procedure of Vogelsang (1997) that allows for detecting a break at an unknown date in the trend function of a dynamic...

In recent years two classes of switching models have been proposed, the Markov switching models, Hamilton (1989) and the Threshold Auto- Regressive Models (TAR), Lim and Tong (1980). These two models have the advantage of being able to modelize and capture asymmetry, sudden changes and...

The aim of this paper is to provide evidence on the nature of the relationship between the terms of trade and the trade balance for US on a scale-by-scale basis using wavelet analysis. Thus, after decomposing the two variables into their time-scale components using to the maximum overlap...

This paper considers bidding automata programmed by experienced subjects in sequential first price sealed bid auction experiments. These automata play against each other in computer tournaments. The risk neutral subgame perfect Nash equilibrium strategy of the independent private value model...

Theoretical study identifying one modality with conditions necesary for the financial stabilization of an inherently unstable system; and 5040 other unstable dynamic modes. It draws on knowledge made available by the academic field of Control Engineering.

In this paper we examine three implementation and interpretation issues associated with Krueger and Summers’s (1988) method for calculating interindustry wage differentials. The literature tends to report a less than complete set of industry wage differentials; use the wrong standard errors;...

This paper uses multiple comparison methods to perform inference on labor market wage gap estimates from a regression model of wage determination. The regression decomposes a sample of workers' wages into a human capital component and a gender specific component; the gender component is called...

In a presentation to the American Economics Association, McCloskey (1998) argued that "statistical significance is bankrupt" and that economists' time would be "better spent on finding out How Big Is Big". This brief survey is devoted to methods of determining "How Big Is Big". It is concerned...

In this paper, we develop methods of the determination of the rank of random matrix. Using the matrix perturbation theory to construct or find a suitable bases of the kernel (null space) of the matrix and to determine the limiting distribution of the estimator of the smallest singular values. We...
