Determinants of Current Account Imbalances in 16 OECD Countries: An Out-Of-Sample Perspective 总被引:1,自引:0,他引:1
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 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

This paper reports on a questionnaire survey about share valuation practices among investors and their intermediaries in Saudi Arabia. The findings suggest that fundamental analysis is used most by investor respondents where a P/E multiple is applied to an earnings forecast to generate a prediction of future price. However, technical analysis is also used to a much greater extent than in developed markets. Finally, the results indicate that quarterly and annual reports as well as newspapers are widely consulted by investors when forming their expectations about share valuations. 相似文献
