The purpose of this paper is to make an appraisal of the tax reforms that took place in Mexico in the eighties and the beginning of the nineties, putting emphasis on their macroeconomic consequences. The paper also examines the pattern of government expenditures along the last three presidential...

This paper provides omnibus tests for multivariate normality of both observations and residuals. They are derived by considering as the alternatives to the multivariate normal a class of maximum-entropy distributions studied elsewhere by the author. The tests, being Lagrange multiplier...

This paper proposes a new real exchange rate index for the Mexican economy. Unlike the methodology currently being employed by the Bank of Mexico, the new index reflects the changing patterns of trade between the country and the rest of the world. The index is calculated on a quarterly basis...

This paper evaluates the indirect tax reforms that took place in Mexico in 1995 and 1998, focusing on their impact on welfare at the household and social levels. The empirical analysis is based on the estimation of an Almost Ideal Demand system, using its correct nonlinear version and by means...

This work surveys possible tributary schemes that might complement or substitute part of the fiscal structure that currently exists in Mexico. Some of the schemes are audacious, as it is the case of the progressive consumption tax, and other reasonable and plausible ones, as it is the case of...

El propósito de este trabajo es analizar, mediante el ejemplo del triplay indonesio importado a México en los noventa, una práctica desleal de comercio que es disfrazada. A saber, el subsidiar de manera indirecta la exportación de una mercancía mediante barreras al comercio de los insumos...

This paper contains a GAUSS program that can be used, among other things, to find equilibria for computable general equilibrium models, and fix-price equilibria for general non-Walrasian models. Simple applications for those two cases, as well as for linear and quadratic programming, are also...

Vector autoregressive models are often used in Macroeconomics to draw conclusions about the effects of policy innovations. However, those results depend on the researcher’s priors about the particular ordering of the variables. As an alternative, this paper presents a simple rule based on the...

El documento pasa revista a cinco posibles alternativas cambiarias que podrían contemplar las autoridades en el momento actual. La primera es seguir con el actual status quo. Una segunda alternativa es la dolarización unilateral. La tercera es dar más mandatos al Banco de México. Una cuarta...

This paper extends the methodology first proposed by Ahmad and Stern for the design of tax reforms that are optimal at the margin. The extension centers on a sharper approximation of welfare measures. The original approach and its variant are illustrated in the case of the current Mexican tax...
