The present paper is structured around two main constructions, fixed points of functors and fibrations and sections of functors. Fixed points of functors are utilized to resolve problems of infinite regress that have recently appeared in economics. Fibrations and sections are utilized to model...

The study presents an analysis of the stochastic nature of the gross domestic product of Mexico for the period 1900-2001. Several specifications to test for the existence of unit roots are presented. The conventional tests, Dickey Fuller, Augmented Dickey Fuller and Phillips Perron, indicate...

Essentially all empirical questions that are addressed with sample data require estimates of sampling variance. The econometrics and statistics literatures show that these estimates depend critically on the design of the sample. The sample for the U.S. Current Population Survey (CPS), which...

Macro-based summary indicators of effective tax burdens cannot provide information on the level or distribution of the marginal effective tax rates thought to influence household behaviour. They also do not capture differences in effective tax rates facing different subgroups of the population....

Inflation can alter the characteristics of tax- and contribution systems in numerous ways. This paper demonstrates how inflation alters the distributive properties of nominally defined tax systems and looks at the impact of the tax revenues and social insurance contribution receipts generated....

This is a new aproach for faster development of Montenegro.

Household micro-datasets often do not contain information on gross incomes. We present an algorithm which exploits the tax- and contribution rules built into tax-benefit models to convert net income information into gross amounts. Using EUROMOD, a multi-country taxbenefit model covering all...

This paper seeks to provide a balanced perspective on the role that benchmarks play in the setting of investment policy, the degree to which asset managers deviate from these benchmarks in pursuit of adding value and the degree to which value is added. The findings of this occasional paper are...

The challenges in the market economy in China for economic theory touch on four topics: private versus public ownership of assets, Western legal systems versus Eastern European semiformal legal systems, individualism versus the collective good, and multiparty versus one party political systems....

This paper studies the impact of external factors on daily exchange rates and short-term interest rates in the Czech Republic, Hungary and Poland during the period August 1997 – May 2001. I find that neither exchange rates nor interest rates are influenced by short-term German interest rates....
