THE OPTIMAL GOVERNMENT SIZE: FURTHER INTERNATIONAL EVIDENCE ON THE PRODUCTIVITY OF GOVERNMENT SERVICES

This paper estimates the optimal government size for several sets of economies by investigating the role of public services in the production process. I assume government services are optimally provided when their marginal product equals unity (the "Barro rule"). The empirical results suggest: (1) government services are significantly productive; (2) they are overprovided in Africa, underprovided in Asia, and optimally provided everywhere else; (3) the optimal government size is 23 percent for the average country but ranges from 14 percent for the average OECD country to 33 percent in South America; and (4) the marginal productivity of government services is negatively related to government size.     

Macroeconomic determinants of migration: the case of Germany, 1964-1988

Macroeconomic determinants of immigration are analysed with pooled cross-country and time series data on net immigration to Germany from European countries during 1964-1988.
Results demonstrate clearly that both high and low frequency determinants have been important. Long run trends are determined by the degree and speed of per capita income convergence between the sending and receiving countries, while year-to-year changes in net immigration flows are dominated by cyclical economic conditions.     

Exchange rate regimes and the cross-country distribution of the 1997 financial crisis

We study variations in the severity of the 1997 financial crisis in a sample of 25 developing countries. We use both currency depreciation and stock market returns as crisis measures. Our key findings are that countries that started 1997 with an exchange rate peg experienced significantly greater currency depreciation and significantly lower stock returns than would be predicted from the levels of various macroeconomic indicators.     

Multidisciplinary eHealth survey evaluation methods

This paper describes the development process of an evaluation framework for describing and comparing web survey tools. We believe that this approach will help shape the design, development, deployment, and evaluation of population-based health interventions. A conceptual framework for describing and evaluating web survey systems will enable the developers of health interventions to identify, select, and use the most appropriate and relevant survey tools. The primary contributors included survey methodologists, computer scientists, informaticians, technical communications specialists, educators, evaluators, clinical practitioners, and health services researchers, who together developed a comprehensive ontology to describe the electronic survey domain. This paper will describe the survey ontology development process and detail lessons learned in the creation of the web survey system evaluation framework.     

EMPLOYMENT AND OUTPUT EFFECTS OF GOVERNMENT SPENDING: IS GOVERNMENT SIZE IMPORTANT?

The efects of government spending on employment and output may depend on government size and the persistence of spending. The empirical results suggest that permanent (or persistent) changes in government consumption have a greater impact on output and employment than temporary (or cyclical) changes. This implies a negative wealth effect and reduces the stabilization potency of government spending. The findings also support the hypothesis that the output elasticity of government consumption is positive but declines with increases in government size. Using the estimated equations, I calculate the optimal government size for the representative country as around 20 percent of GDP.
