The characteristics of hierarchical trade flows, when placed in the context of differentiated markets, can provide some insight into the underlying bases of contemporary international trade. A model that relies on differentiated market theory and hierarchical market theory is developed. Trade characteristics derived in the model, concerning the frequency and value of trade, are empirically tested. Empirical results indicate that the model provides a useful framework for the analysis of contemporary international trade. 相似文献

Monitoring is deemed crucial for the incentivization of a decentralized organization, but its function relies on information transparency between the central authority and the delegated individuals. We test this hypothesis by considering changes in the fiscal behavior of Chinese county governments following an exogenous fiscal reform in 2004/2005 that removed information obstacles between provinces and counties. Employing data on 590 Chinese counties from 2000 to 2009, we find that counties in the reform provinces adopt a more proactive fiscal policy after the reform, suggesting that they become more incentivized in the political competition for economic growth. Such effects are stronger in counties with fewer competing peers and counties with either high or low ranks in the records of economic growth among peers. The increase in counties' productive spending leads to higher economic growth in later years. 相似文献

This paper provides observations on recent patterns of the Soviet Union's foreign trade in the context of factor endowment trade theory and two models drawn from the new trade theory. Empirical analysis indicates that recent Soviet foreign trade was not based on differing factor intensities between Soviet goods and the those of the rest of the world. Instead, the recent geography of Soviet foreign trade suggests that it conformed more to the trade in differentiated products expected under the new trade theory. These results suggest that Soviet foreign trade had developed in such a way that, at least with respect to merchandise trade, the Commonwealth of Independent States (CIS) has a strong potential for fairly rapid integration within the group of industrial countries. 相似文献

A lack of clear political commitment together with confusing rules and enforcement often characterize the institutional context of policy implementation and regulatory compliance in developing countries. By connecting such contextual features to existing models of policy implementation and regulatory compliance, we examine how regulatory factors are related to basic and proactive corporate environmental management practices in the Pearl River Delta region in China. Drawing on data derived from both a survey and in‐depth interviews, we show that a perception of clear political commitment to environmental protection across multiple government levels and units is positively associated with business efforts in basic environmental practices, regardless of the specific enforcement intensity. Nevertheless, a perception of clear political commitment is not related to proactive environmental practices. Conversely, a perception of policy ambiguity, in the form of confusing regulatory standards and enforcement, is negatively associated with corporate efforts in both basic and proactive environmental practices; yet, intensive inspections mitigate these negative associations with policy ambiguity. 相似文献
