The nexus between trade and economic growth in Italy has been widely debated by historiography. However, there are no long run analyses on this topic that cover the whole span from Unification to present days. This paper contributes to fill this gap by investigating the relationship between real exports, imports and GDP in Italy from 1863 to 2004 by using cointegration analysis and causality tests. The outcome suggests that these variables comove in the long run but the direction of causality varies across time. In the period prior to the First World War import growth led GDP growth that in turn led export growth. Conversely, in the post-Second World War period we have a strong bidirectionality between imports and exports consequent on the increase in intra-industry trade. We also find a weak support for export-led growth and growth-led imports. This suggests that exports were not the only or the main driver of economic growth. There was probably a multiplicity of factors at work, among which high rates of capital formation and the expansion of internal demand probably stood out.  相似文献

This longitudinal study explored the relationship between perceived breast cancer risk and worry. We measured both absolute and comparative risk perceptions, and also used the Gail algorithm to assess the accuracy of participants' risk perceptions. Three hundred and one women ages 40–75 participated in a two‐part study assessing how format of breast cancer risk presentation affected perceptions of risk. Relative to their Gail scores, women were biased pessimistically about their own absolute breast cancer risk and yet largely accurate about their comparative breast cancer risk. Perceived comparative risk, but not perceived absolute risk or biases in absolute or comparative risk, predicted subsequent worry. Worry predicted subsequent perceived absolute risk and biases in absolute and comparative risk. These results suggest that women's emotional reactions to breast cancer risk are based on accurate (unbiased) perceptions of their comparative risks. In turn, greater worry prompts a re‐evaluation of absolute risk as well as changes in risk biases. Implications for screening are discussed.  相似文献

In international relations, short‐run incentives for non‐cooperation often dominate. Yet, (external) institutions for enforcing cooperation are hampered by national sovereignty, supposedly strengthening the role of self‐enforcing mechanisms. This paper examines their scope with a focus on contingent protection aka tit‐for‐tat in trade policy. Highlighting various strategies in a partial equilibrium framework, we show that retaliation of non‐cooperative behaviour by limiting market access works as a disciplining device quite independently of supply and demand parameters. Our empirical findings are consistent with the theoretical results in that countries more frequently involved in WTO‐mediated disputes entailing tit‐for‐tat strategies pursue on average more liberal trade regimes.  相似文献

This Dialogue presents the views of four authors, from the US, the UK, and Norway, on the best policies to help lone mothers. Lone mothers face an inevitable dilemma in allocating their time between earning income and caring for their children. The low-earning capacity of women in an unequal labor market exacerbates the problem, causing material hardship for many lone mothers and their families. The policy solutions proposed lie along a spectrum, ranging from those that seek to enable all lone mothers to take employment to those that aim to let mothers choose whether to take employment or care for their children themselves. Other policies discussed concern ways to value and support caregiving, improve the low-wage labor market for women, and provide a set of income supports that would both boost income and provide time to care for children.  相似文献

Pen-Papier der DGKH - Der korrekte Umgang mit Insulin-Pens ist offensichtlich nicht ganz einfach. Die Deutsche Gesellschaft für Krankenhaushygiene (DGKH) erh?lt immer wieder Anfragen, ob die Hautantiseptik vorab notwendig sei oder ob Pen-Nadeln mehrfach verwendet werden dürfen. Deshalb aktualisierte die DGKH jetzt ihr Konsensuspapier und bündelt darin die Empfehlungen der Experten.  相似文献

Children's television advertising is rapidly becoming a major concern to government agencies, citizens' groups and researchers in many areas of the social sciences. To this point there has been little integration of research efforts. This article presents a model of the processing of television advertising by children in order to organize and integrate previous research results and to act as the basis for suggesting future directions for research. The authors indicate that more involvement by advertisers is needed.  相似文献
