Specialisation,localisation, and trade value in the wake of cross-border production sharing. The Central Eastern European Countries' case 总被引:1,自引:0,他引:1
Gianfranco De Simone 《International Review of Economics》2007,54(1):106-128
We focus on five among the sectors in which most of the CEECs’ trade in middle products with EU-15 is concentrated. Over the
second half of the 1990s, we observe remarkable changes in both production and trade specialization as well as a significant
relocation of industries within CEECs. Using jointly trade and production data we outline co-movements in the adjustment of
specialisation patterns. We also show that the redistribution of activities at the regional level reflects the relocation
of industries at the global level. Finally, we try to detect the scope of fragmentation of production characterizing each
industry and the ways in which CEECs are moving along the “internationally sliced-up value chain”. (JEL: F10, F14, F15) 相似文献

The methodology in this paper combines an input–output structural decomposition approach with the supply-side perspective of mainstream growth accounting. In explaining the intertemporal change in consumption per worker, three sets of effects are distinguished. First, contributions due to several types of technological changes are considered. Second, effects caused by changes in international trade are discerned. Third, composition effects that reflect structural shifts in demand (including changes in tastes) are quantified. As an empirical illustration, we analyze the developments in the U.K. between 1979 and 1990. 相似文献

This paper empirically investigates the development of cross-country differences in energy- and labour productivity. The analysis
is performed at a detailed sectoral level for 14 OECD countries, covering the period 1970–1997. A σ-convergence analysis reveals
that the development over time of the cross-country variation in productivity performance differs across sectors as well as
across different levels of aggregation. Both patterns of convergence as well as divergence are found. Cross-country variation
of productivity levels is typically larger for energy than for labour. A β-convergence analysis provides support for the hypothesis
that in most sectors lagging countries tend to catch up with technological leaders, in particular in terms of energy productivity.
Moreover, the results show that convergence is conditional, meaning that productivity levels converge to country-specific
steady states. Energy prices and wages are shown to positively affect energy- and labour-productivity growth, respectively.
We also find evidence for the importance of economies of scale, whereas the investment share, openness and specialization
play only a modest role in explaining cross-country variation in energy- and labour-productivity growth.

This paper presents a simple model which illustrates the possible policy- and welfare-implications of endogenous product selection in the postal sector. The cost of a unit of mail depends on its "quality" (e.g., speed of delivery) and on the type and location of the addressee (firms, urban households, and rural households). Senders have inelastic demands and differ in their willingness to pay for quality. Addressees are passive but their utility may affect social welfare. Two operators play a two-stage game, first choosing qualities and then prices. We first show that the equilibrium with two private (profit maximizing) operators results in an inefficient provision of quality. Then, we consider the mixed (Nash) equilibrium with one private and one (welfare maximizing) public operator. If the budget constraint of the public firm is not binding, this equilibrium is shown to be first-best efficient even if social welfare accounts for the utility of addressees. If the budget constraint is binding, the mixed equilibrium is not efficient but yields a higher level of welfare than the private equilibrium. Finally, we study the impact of minimum quality standards within our setting. 相似文献

An analysis of the impact of migration to the United States on the sending community and on the labor market in the receiving country is presented based on a case study of Las Animas, Mexico. "As the community becomes increasingly involved in migration, tendencies can be identified regarding changing migration patterns, class differentiation among villagers, impact of migration on village economy, and the changing role of Mexican workers in California labor markets. Results indicate the importance of social networks in determining the outcome of migration; while migration is individually rational, it is a factor of stagnation for village economy, and it helps reproduce segmented California labor markets." 相似文献

We investigate the determinants of direct office real estate returns by analyzing rents, capital appraisals, and total returns. A recently compiled global database of major cities in Asia, Europe, and the United States provides a unique opportunity to give a macro-view on the effects of economic growth and supply and demand factors on nominal real estate returns. The global database provides quarterly observations from 1986 to 1999. To address the smoothness problem of appraisal-based price data and regulated rents, we employ the Generalized Method of Moments to estimate a dynamic panel-data model. The model allows us to combine the cross-sectional and time-series dimension in our quarterly data. We find that gross domestic product, inflation, unemployment, vacancy rate, and the available stock all have an effect on real estate returns. 相似文献
