Can the Augmented Solow Model with Migration Explain the Italian Internal Brain Drain?

We extend the Dolado et al. (1994) model to both inflows and outflows of migrants and assume that they have a human capital endowment that contributes to increase/decrease the stock of human capital in the receiving/sending economy. We derive the conditional convergence equation in which the impact of migration flows on the growth rate is disentangled in a pure quantity effect and in a quality or composition effect of immigration and emigration rates that accounts for the relative human capital endowment of migrants with respect to resident population. Next, we test the model with Italian regional data for the 1970–2005 time period. We find that the model provides a good explanation of the Italian experience. The quantity effect is negative for the immigration rate and positive for the emigration rate, whereas the composition effect is positive for immigration and negative for emigration. Finally, we separate the centre‐north from the south and find that the composition effect of emigration is stronger for the latter. We interpret these results as a clear evidence of a brain drain from the Mezzogiorno to the centre‐northern regions.     

Effects of urbanization on trust: Evidence from an experiment in the field

I conducted a trust game in the field within a natural experiment paradigm to test the effects of urbanization on both in- and out-group trust. I found that urbanization has a larger positive effect on out-group trust than on in-group trust. My findings provide new knowledge to the literature on the intricacy of the urbanization-trust relationship and contribute to the ongoing discourse on the different foundations underpinning in-group and out-group trust.     

A panel study of migration,self-selection and household real income

The impact of migration on income for Swedish multi-adult households is examined using panel data pertaining to a sample of stable household constellations during the period 1980–1990. In contrast to previous studies, data on household disposable income is employed in estimating the income function. The empirical results indicate no significant effect on real disposable income from migration. In addition, the hypothesis of no self-selection, or zero correlation between the errors in the decision function and the income function, cannot be rejected.

Does inflation targeting lower inflation and spur growth?

Over the last few decades several countries have turned to inflation targeting as a policy choice for instilling stability into their economies. Prior studies have shown that inflation targeting has reduced inflation in those countries without significantly impacting GDP. This study seeks to improve upon these results by identifying the impact of timing on the policy decision as well as its impact as related to specific regions of the world. The focus is on developing countries across six regions. We find significant regional variation in developing countries in our sample in terms of the direction of changes in inflation following a switch to the inflation targeting policy. Moreover, although the impact of inflation targeting on real GDP is minimal overall, there is a statistically significant increase in real GDP among developing countries in certain regions only, namely, Europe, Latin America, and the Middle East.

良好的托管,诗意的人生——生态神学视野下的亚历山德拉

《啊,拓荒者!》是凯瑟以拓荒者生活为素材创作的第一部长篇小说。在小说中,作家塑造了一位高大的生态女性形象——亚历山德拉,她不辱上帝的使命,在拓荒的过程中对土地实施了良好的托管,建构了诗意的人生,实现了自我超越与生命价值的升华。以生态神学批评的视角欣赏这部作品,有助于推动自然生态与人文精神生态之间的良性互动,重新审视人与自然的关系,建设一个健康、和谐的生物共同体。     

尤金·奥尼尔晚期作品中的荒诞主题

对戏剧技巧的大胆实验和对人生真谛的不倦探索造就了奥尼尔剧作的多层面特征：早期剧作的自然主义倾向;中期剧作的表现主义特征;以及晚期剧作的存在主义色彩。从后现代主义文学荒诞派戏剧的视角重新审视,奥尼尔的晚期四部剧作讨论了孤独之处境、徒劳之人生、死亡之终局的荒诞主题。
