Abstract
The trend in the BMI values of US children has not been estimated very convincingly because of the absence of longitudinal data. Our objective is to estimate time series of BMI values by birth cohorts instead of measurement years. We use five regression models to estimate the BMI trends of non-Hispanic US-born black and white children and adolescents ages 2-19 between 1941 and 2004. The increase in BMIZ values during the period considered was 1.3 (95% CI: 1.16; 1.44) among black girls, 0.8 for black boys, 0.7 for white boys, and 0.6 for white girls. This translates into an increase in BMI values of some 5.6, 3.3, 2.4, and 1.5 units, respectively. While the increase in BMI values started among the birth cohorts of the 1940s among black girls, the rate of increase tended to accelerate among all four ethnic/gender groups born in the mid-1950s to early-1960s. Some regional evidence leads to the conjecture that the spread of automobiles and radios affected the BMI values of boys already in the interwar period. We suppose that the changes in lifestyle associated with the labor saving technological developments of the 20th century are associated with the weight gains observed. The increased popularity of television viewing was most prominently associated with the contemporaneous acceleration in BMI gain. Am. J. Hum. Biol., 2009. © 2008 Wiley-Liss, Inc.

Subsidiary Roles, Vertical Linkages and Economic Development: Lessons from Transition Economies
Björn Jindra, Axèle Giroud, J. Scott-Kennel
Journal of World Business,
2009
Abstract
Vertical supply chain linkages between foreign subsidiaries and domestic ?rms are important mechanisms for knowledge spillovers, contributing to the economic development of host economies. This paper argues that subsidiary roles and technological competences affect the extent of vertical linkages as such as well as their potential for technological spillovers. Using survey evidence from 424 foreign subsidiaries based in transition economies, we tested for the effect of subsidiaries’ autonomy, initiative, technological capability, internal and external technological embeddedness on the extent and intensity of forward and backward vertical linkages. The evidence supports our main argument that the potential of technology diffusion via vertical linkages depends on the nature of subsidiary roles. We discuss the implications for transition as well as other developing countries.

Ownership Structure, Strategic Controls and Export Intensity of Foreign-invested Firms in Transition Economies

Abstract
This paper examines the relationships between foreign ownership, managers’ independence in decision-making and exporting of foreign-invested firms in five European Union accession countries. Using a unique, hand-collected data set of 434 foreign-invested firms in Poland, Hungary, Slovenia, Slovakia and Estonia, we show that foreign investors’ ownership and control over strategic decisions are positively associated with export intensity, measured as the proportion of exports to total sales. The study also analyzes specific governance and control configurations in foreign-invested firms, showing that foreign equity and foreign control over business functions are complementary in terms of their effects on export intensity.

Implementation of Competition Law in Developing and Transition Countries. Theoretical and Empirical Considerations

Abstract
The success of free market economies over the last 200 years supports the notion that competition increases individual and social wealth. Developing countries that have undergone the necessary reforms today are amongst the most driving “emerging” economies in the world.

The Role of the Human Capital and Managerial Skills in Explaining the Productivity Gaps between East and West
Wolfgang Steffen, Johannes Stephan
IWH Discussion Papers,
Nr. 11,
2007
Abstract
This paper assess determinants of productivity gaps between firms in the European transition countries and regions and firms in West Germany. The analysis is conducted at the firm level by use of a unique database constructed by field work. The determinants tested in a simple econometric regression model are focussed upon the issue of human capital and modern market-oriented management. The results are novel in as much as a solution was established for the puzzling results in related research with respect to a comparison of formal qualification between East and West. Furthermore, the analysis was able to establish that the kind of human capital and expertise mostly needed in the post-socialist firms are related to the particular requirements of a competitive marketbased economic environment. Finally, the analysis also finds empirical support for the role of capital deepening in productivity catch-up, as well as the case that the gaps in labour productivity are most importantly rooted in a more labour-intense production, which does not give rise to a competitive disadvantage.

The relationship between unemployment and output in post-communist countries
Hubert Gabrisch, Herbert Buscher
Post-Communist Economies,
2006
Abstract
Unemployment is still disappointingly high in most Central and East European countries, and might be a reflection of the ongoing adjustment to institutional shocks resulting from systemic transition, or it may be caused by high labour market rigidity, or aggregate demand that is too weak. In this paper we have investigated the dynamics of unemployment and output in those eight post-communist countries, which entered the EU in 2004. We used a model related to Okun’s Law; i.e. the first differences in unemployment rates were regressed on GDP growth rates. We estimated country and panel regressions with instrument variables (TSLS) and applied a few tests to the data and regression results. We assume transition of labour markets to be accomplished when a robust relationship exists between unemployment rate changes and GDP growth. Moreover, the estimated coefficients contain information about labour market rigidity and unemployment thresholds of output growth. Our results suggest that the transition of labour markets can be regarded as completed since unemployment responds to output changes and not to a changing institutional environment that destroys jobs in the state sector. The regression coefficients have demonstrated that a high trend rate of productivity and a high unemployment intensity of output growth have been occurring since 1998. Therefore, we conclude that labour market rigidities do not play an important role in explaining high unemployment rates. However, GDP growth is dominated by productivity progress and the employment-relevant component of aggregate demand is too low to reduce the high level of unemployment substantially.
