A decomposition of trends in U.S. consumer expenditures on communications and travel: 1984–2002

This paper offers a conceptual and partly empirical decomposition of the trends in U.S. consumer expenditures on five communications and nine transportation subcategories between 1984 and 2002. We find that inflation nearly always increases unit prices. Income effects are positive for all categories, meaning that these are all normal goods, not inferior ones. We speculate that taste changes have contributed to increasing expenditures in most categories, with the exception of out-of-town lodging, the public transit component of the public transportation category, and the old communication media categories of postage and reading. We suggest that production and technological changes have led to decreased unit prices in most categories. In the private vehicle operations categories, technological improvements dominate, so that expenditure shares have been decreasing despite increasing demand. Conversely, in the new media categories, taste changes dominate, so that expenditure shares are increasing despite technological improvements which lower prices. The decomposition explored here enhances our understanding of these important expenditure categories, and provides a useful methodology with which to examine trends in other categories as well.     

Taxes,economic conditions and recent trends in male self-employment: a Canada–US comparison

North American workers have increasingly turned to self-employment since the 1970s. Using microdata for the period 1983–1994 from Canada and the United States, I assess the importance of macroeconomic conditions and the tax environment in explaining the trends in male self-employment in these two countries. My findings suggest that higher income tax and unemployment rates are associated with an increase in the rates of self-employment among North American men. Changes in the tax environment account for a considerable amount of the secular trends in male self-employment over this period, while changing economic conditions played a smaller role in determining these trends.     

The effects of U.S. monetary policy on Colombia and Panama (2002–2007)

I study the economies of Colombia (floating exchange rate) and Panama (dollarized) to illustrate how the monetary policy of a large economy can export capital structure distortions to small open economies that follow different exchange rate regimes. The paper contributes to the literature on international business cycles in two ways. First, it adds to recent research that extends the Mises–Hayek business cycle theory to an international context. Second, most current research abstracts from effects on the production structures of emerging market economies when analyzing the transmission of monetary policy shocks. This paper seeks to fill this gap by studying structural effects of U.S. monetary policy on the economies of Colombia (floating exchange rate) and Panama (dollarized).     

Developing key human resources in China: an assessment of University Management Schools in Beijing,Shanghai and Tianjin in the decade 1979–88

This article focuses on differences and dynamics with respect to the organization of learning at work. It starts with a reflection on actual research perspectives on the subject of training in organizations. Four perspectives, which are currently dominant in the educational and social sciences, will be discussed: the structure-oriented approach, the system-oriented approach, the actor-oriented approach and the network approach. The network approach is a particularly promising new development in training research. We will elaborate this approach here and illustrate its potential by applying it to the analysis of training systems in two different types of organizations: bureaucratic and professional organizations. Data from recent case studies demonstrate that these types of organizations show remarkable differences with respect to the basic processes of their training systems: the shaping of training policies, the development of training programmes and the execution of training activities. In practice, training systems are much more organization-specific than training literature usually suggests. A network approach to training can provide a better understanding of the backgrounds of this organizational variety.
