This paper analyzes the properties of mutual encompassing and its relationship to the KLIC equivalence between statistical models. It is shown that models are KLIC equivalent if and only if they are mutually encompassing and mutually Cox-encompassing. Further, within the exponentional familly...

Recently, Vogelsang (1999) proposed a method to detect outliers which explicitly imposes the null hypothesis of a unit root. It works in an iterative fashion to select multiple outliers in a given series. We show, via simulations, that under the null hypothesis of no outliers, it has the right...

We propose residual based tests for cointegration using local GLS detrending (Elliott, Rothemberg and Stock (1996), ERS) to eliminate separately the deterministic components in the series. We consider two cases, one where only a constant is included and one where a constant and a time trend are...

I illustrate the convergence to Rubinstein's (1982) bargaining outcome of the solutions of the finite-horizon truncations of that game. The depiction is new, and hopefully instructive, and has the flavour of international trade diagrams.

OLS estimates of the rate of return to education are subject to a number of potential biases. Recent developments in the literature have focused particularly on exploiting alternative instruments, arising naturally in the data, to counteract these problems. A number of such instrumens are...

This paper has pushed Becker's matching insights into a quite plausible search setting. Exploiting the implicit integral equation (10), we gave a thorough characterization of cross-sectional matching patterns in the equilibrium and constrained s ocial optimum of a frictional matching model. In...

Se presenta una visión analítica global de la información de un sistema económico y su modelo de representación econométrico, proyectando nuestro propósito hacia la descripción de elementos, relaciones y procesos presentes en él que, siendo aparentemente completos o incluso inconexos,...
