A cross-sectional relationship between price dispersion among Russian regions and per capita income dispersion is used to measure the degree of integration between regional commodity markets. The sequence of cross-sectional estimations for each month of the period spanning 1992 through 2000...

The problem of detecting unit roots in univariate and multivariate time series data is treated as a problem of multiple decisions instead of a testing problem, as is otherwise common in the econometric and statistical literature. Four examples for such multiple decision designs are considered:...

We verify whether cocoa prices could be a source of inflation in five countries of the West African region within a framework that includes other variables such as migrant remittances to the region and a fiscal policy variable represented by the government budget deficit. Unlike earlier studies...

Austria is among the very few countries in the European Union which have managed to maintain comparatively low unemployment rates and high employment rates. In international comparison Austrian unemployment is very stable over the business cycle. This is mainly due to the high sensitivity of the...

In this study we use a long run macroeconomic model for Austria to simulate the effects of aging on employment, output growth, and the solvency of the social security system. By disaggregating the population into six age cohorts and modelling sex specific participation rates for each cohort, we...

In a panel of West African countries, we investigate whether data on immigrant remittance flows can be used to improve on predictive accuracy of aggregate demand in a systematic way. The results of the prediction experiments are compared to traditional significance tests of asymmetric error...

This paper investigates the properties of knowledge production in academic research using a panel of 17 OECD countries reaching from 1989 to 1996. The production process is modelled using capital and labour as inputs and the number of published international journal articles and/or the number of...

This paper discusses the theoretical and practical aspects of new methods for solving DEA problems under real-life geometrical uncertainty and probability uncertainty of sample data. The proposed minimax approach to solve problems with geometrical uncertainty of sample data involves an...

Since the early seventies, hundreds of authors have calculated gender wage differentials between women and men of equal productivity. This meta-study provides a quantitative review of this vast amount of empirical literature on gender wage discrimination as it concerns differences in...

In this paper we estimate income elasticities and own- and cross-price elasticities for a number of categories of goods. The methodology used was proposed by Deaton (1987). Expenditure and quantity data from Household Budget Surveys for Bulgaria are used. The households are geographically...
