The role of tourism is of vital economic importance, particularly for small countries with a privileged geographical location and favourable weather conditions. This paper examines the importance of tourism as a conditioning factor for higher regional growth in Portugal by employing the conditional convergence hypothesis of Barro and Sala-i-Martin, associated with the endogenous growth theory. The panel data estimation approach provides evidence of the positive impact of tourism (through the accommodation capacity) on the growth in per-capita income among the Portuguese regions, increasing the rate of convergence. Therefore, tourism can be considered as an alternative source for stimulating higher regional growth in Portugal, if the supply characteristics of this sector are improved. 相似文献

The demand for and supply of analysts’ opinions in this model yield an equilibrium that demonstrates how the information content
of the opinions reacts to changes in exogenous parameters. The model also shows how changes in the parameters make analysts’
opinions more or less dispersed; for example, a decline in investor risk aversion, a decrease in market volatility, and an
increase in information costs can lead to analysts’ opinions becoming more similar. Recognizing how exogenous factors can
affect the supply and demand of analysts’ opinions gives additional insights into questions concerning what may appear to
be herd behavior by analysts and also the relationship between forecast dispersion and information content. (JEL: G29, C71) 相似文献

Much of the debate about rising health care costs in the United States centers on the notion of "cost shifting." Cost shifting is loosely defined as charging one set of patients a higher price to offset losses on another set of patients. One aspect of the cost shifting debate that the empirical work has ignored is whether or not doctors—as opposed to hospitals—practice cost shifting. The analysis here investigates this question using the Physicians' Practice Costs and Income Survey, 1983–1985 (PPCIS, expanded version)
Using variation across states in Medicaid reimbursements, the analysis finds that lower Medicaid reimbursements tend to lower the fees physicians charge, contradicting the standard cost shifting story. Evidence also suggests that lower Medicaid reimbursements tend to cause physicians to treat fewer Medicaid patients. These results are consistent with profit maximizing behavior for physicians and also with the hypothesis that physicians exert some monopoly power. 相似文献
