We employ panel data as well as country-specific models to uncover empirically the determinants of current account imbalances. We find evidence of slope heterogeneity likely rendering the fixed-effect estimator inconsistent. Mean group estimation is followed to overcome the latter difficulty. Both estimation techniques are evaluated by means of in- and out-of-sample criteria. The mean group estimator outperforms the fixed-effect approach and, moreover, only three economic variables are found to impact on the current account balance significantly. These are the government budget balance, the domestic output gap and the changes of the terms of trade. We finally propose a parsimonious dynamic model of the current account, including only these variables and illustrate that it has similar predictive accuracy as country-specific benchmark models.

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 anthropological project, tired and exhausted after years searching for ‘methodological absolution’, remains mired in a spiral of self-doubt and self-indulgent ‘crisis’. Anthropological teaching continues the very complicities that a self-critical reflexivity professed to avoid. Co-option and incorporation, even at the best of times. This essay asks just what would break the cycle of ‘suicidal rejoicing’ for an ‘end of anthropology’ that never comes, that continues to be taught anew, over and over? Nietzsche once suggested that what is falling down should be pushed. A reconfigured anthropology would be a different discipline, perhaps reinvesting the tasks of knowledge production with a purpose that was not wholly slave to the same interests of power. There is much to be cleared away.  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.

Previous tests for structural changes (slope changes) and shifts (intercept changes) in the Phillips curve and union wage determination specify the date of structural change a priori. This article tests for structural changes and shifts without specifying the change point ex ante . The results support the belief that structural changes occurred in the early 1980s. Contrary to some previous research, however, the results do not support a structural shift in the Phillips curve.  相似文献

Leading financial economists and activist institutional investors have long argued that the proper alignment of manager and shareholder interests requires the use of performance based compensation. Partly in response to these pressures, and in combination with a change in the tax code that encourages performance-based pay, corporate boards have dramatically increased their use of stock grants and executive stock options. Combine this development with the longest bull market in U.S. financial history, and the result is unprecedented levels of CEO pay at the close of the 20th century. This review of executive compensation reveals that the economic theory of tournaments may provide a rationale for the pattern, if not the level, of executive pay. Specifically it finds that the total compensation of the five highestpaid executives in a cross-section of new and old-economy firms is very similar to the pattern of payouts to players in a golf tournament. The author also reports that recent studies show a significant increase in the pay-for-performance correlation throughout the 1990s. But whether that correlation is as high as it should be, and whether current levels of CEO pay are socially "optimal," are questions that remain unanswered.  相似文献
