This paper extends the established Helpman (1993 ) model by introducing international capital movement, and obtains new results concerning the welfare implications of tightening intellectual property rights (IPR) in the South. First, if separated capital markets in the North and the South are integrated, enforcement of IPR would have more desirable welfare effects in both regions. Second, when international capital movement is allowed, the North always gains from the tightening of IPR if the imitation rate is sufficiently high. This implies that the North's demand on the South to tighten IPR becomes stronger as the integration of international capital markets progresses. 相似文献

This paper studies the effects of labor supply on relative wages in a dynamic North–South model of trade. Lai (1995 )—a generalization of the Grossman and Helpman (1991a,b , ch. 11) models—showed that the relative wage of skilled (unskilled) labor in a region is positively (negatively) related to the supply of skilled (unskilled) labor in that region. These surprising results depend crucially on the specification of the functional form of the Southern imitation activity. We will show that these results (except for the relative wage of unskilled labor in Lai) are reversed in the case where the productivity of imitation depends only on the number of products the North manufactures. 相似文献

We examine the issues of hypothetical bias, demand revelation, and gender differences in a threshold public goods experiment
with heterogeneous induced-values. First, we find no evidence of hypothetical bias in our threshold provision public goods
experiments, despite the fact this is an open-ended type mechanism. Our results support recent experimental findings that
use induced-values to investigate hypothetical bias. Second, we investigate the demand revealing performance of real and hypothetical
payments and find no evidence that real payment performs better than hypothetical payment in our experiments. Third, we examine
whether payments, real and hypothetical, are positively related to induced-values. Our results suggest there is statistical
evidence that payments are positively related to true values. Finally, we examine the effect of gender on real and hypothetical
payments in our experiment. The results show that gender matters for contributions through both real and hypothetical payments,
after controlling for true values as well as socio-economic variables. Results also indicate that females are more likely
to truthfully reveal their value than males through hypothetical payments, but gender is not significant for truthfully revealing
their value through real payments. 相似文献
