It is frequent to hear in economic seminars or read in academic papers that an effect is economically significant or economically important. Yet, the economic literature is vague on what economic importance means and how it should be measured. In this paper, I show that existing measures of economic importance are flawed and misused. I derive a new metric that measures, in percentage terms, the contribution of each explanatory variable to deviations in the dependent variable, ceteris paribus. As an illustration, the method is applied to study the determinants of migration and the determinants of fertility. 相似文献

Governments and central banks need to have an accurate and timely assessment of indicators for the current month, as this is essential for providing a reliable and early analysis of the current economic situation. The index of industrial production (IIP) is probably the most important and widely analyzed monthly indicator, given the relevance of the manufacturing activity as a driver of the whole business cycle. This paper presents a series of models conceived to forecast the current French monthly IIP, based on regression models and dynamic factor models. The combination of these two approaches allows selecting economically relevant explanatory variables among a large data set. In addition, a rolling forecast study is carried out to assess the forecasting performance of the estimated models, using predictive ability and model confidence set tests. This latter allows getting several models displaying equivalent forecasting performance and therefore gives robustness to the forecasting exercise rather than to base the forecasting analysis only on one model. 相似文献

As their environment changes, migrants constitute an interesting group to study the effect of relative income on subjective well-being. This paper focuses on the huge population of rural-to-urban migrants in China. Using a novel dataset, we find that the well-being of migrants depends on several reference groups: it is negatively affected by the income of other migrants and workers of home regions; in contrast, we identify a positive, ‘signal’ effect vis-à-vis urban workers: larger urban incomes indicate higher income prospects for the migrants. These effects are particularly strong for migrants who wish to settle permanently, decline with years since migrations and change with other characteristics including work conditions and community ties. 相似文献

The relevance of political affinity for the initial acquisition premium in cross‐border acquisitions 下载免费PDF全文
Research summary : In the context of economic nationalism, we investigate the relevance of political affinity between countries to the initial acquisition premium offered in cross‐border acquisitions. Political affinity is defined as the similarity of national interests in global affairs. We argue that political affinity affects how foreign acquirers anticipate their bargaining position in their negotiations with domestic target firms. With decreasing political affinity, the host government becomes increasingly likely to intervene against foreign firms in an acquisition deal. Consequently, foreign acquirers need to provide a more lucrative initial offer to dissuade target firms from leveraging government intervention to oppose the acquisition. Our prediction is supported by strong evidence that political affinity, as revealed by UN general assembly voting patterns, leads to lower initial acquisition premiums. Managerial summary : Media reports suggest that politics plays an important role in international business transactions. However, we still know very little about how bilateral political relations affect corporate decision‐making. In this article, we analyze the influence of the quality of bilateral political relations on the bidding behavior of foreign acquirers in cross‐border acquisitions. We argue that the host government is more likely to intervene against the foreign acquirer during deal negotiations if the quality of bilateral political relations is poor. A lower political affinity between countries therefore decreases the bargaining power of the acquirer and pushes up the initial bid premium the acquirer has to offer to the local target. Our empirical results confirm our argument. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献

In this paper we present a statistical analysis of four foreign exchange spot rates against the U.S. Dollar with several million intra-day prices over 3 years. The analysis also includes gold prices and samples of daily foreign exchange prices over 15 years. The mean absolute changes of logarithmic prices are found to follow a scaling law against the time interval on which they are measured. This empirical law holds although the distributions of the price changes strongly differ for different interval sizes.Systematic variations of the volatility are found even during business hours by an intra-day analysis of price changes. Seasonal heteroskedasticity is observed with a period of one day as well as one week as the result of an analogous intra-week analysis; taking this into account is necessary for any future study of intra-day price change distributions and their generating process. The same type of analysis is also made for the bid-ask spreads. 相似文献

It is sometimes argued that road safety measures or automobile safety standards fail to save lives because safer highways or safer cars induce more dangerous driving. A similar but less extreme view is that ignoring the behavioral adaptation of drivers would bias the cost–benefit analysis of a traffic safety measure. This article derives cost–benefit rules for automobile safety regulation when drivers may adapt their risk‐taking behavior in response to changes in the quality of the road network. The focus is on the financial externalities induced by accidents because of the insurance system as well as on the consequences of drivers' risk aversion. We establish that road safety measures are Pareto improving if their monetary cost is lower than the difference between their (adjusted for risk aversion) direct welfare gain with unchanged behavior and the induced variation in insured losses due to drivers' behavioral adaptation. The article also shows how this rule can be extended to take other accident external costs into account. 相似文献

This overview article sets out the broad themes behind the transformation of local political leadership, in particular the forces that have led to the introduction of stronger forms of local executive, such as directly elected mayors. After setting out the role of local political leadership in traditional local government and different traditions and patterns across Western Europe, the article sets out the likely factors driving the changes toward a stronger form of leadership in the more complex pattern of governing described as local governance: complex networks, the ‘new political culture’, Europeanization of public policy and institutional mimetism. The article observes that the articles in this symposium do not fully confirm these hypotheses, showing the complexity of the responses and the different contexts across Western Europe. The concluding sections draw together the implications of the stronger forms of local executive for the current practice and functioning of local politics and policy‐making: the legitimacy crisis that may have emerged from more autonomous political leaders, which combines with the decline in the conventional measures of local political participation; the lack of complementary institutional resources to assist the performance of the enhanced executive function; and the emergence of a new north‐south divide in governing styles. Cet article général expose les grands thèmes qui sous‐tendent la transformation de l'autorité politique locale, notamment les forces qui ont conduit à l'introduction de formes d'exécutif local plus puissantes, comme l'élection des maires au suffrage direct. Après avoir expliqué le rôle d'une autorité politique locale dans un contexte classique et selon plusieurs traditions ou modèles d'Europe occidentale, l'étude s'intéresse aux facteurs susceptibles de tendre vers une forme plus forte d'autorité dans le cadre pluscompliqué d'une gouvernance locale intégrant réseaux complexes, ‘nouvelle culture politique’, européanisation des politiques publiques et mimétisme institutionnel. Les articles proposés pour ce symposium ne confirment pas totalement ces hypothèses, révélant la sophistication des réponses et la multiplicité des contextes européens. La conclusion déduit ce qu'implique le renforcement de l'exécutif local dans la pratique et le fonctionnement actuels de la politique et du processus décisionnel locaux: crise de légitimité, éventuellement née de leaders politiques plus autonomes, combinée au déclin des dispositifs classiques de participation locale; manque de ressources institutionnelles complémentaires qui faciliteraient la mise en ?uvre de la nouvelle fonction exécutive; émergence d'une scission nord‐sud dans les styles de gouvernement. 相似文献

All preferential trading agreements (PTAs) short of a customs union use rules of origin (ROO) to prevent trade deflection. ROO raise production costs and create administrative costs. This paper argues that in the case of the recent wave of North–South PTAs, the presence of ROO virtually limits the market access that these PTAs confer to the Southern partners. In the case of NAFTA, we find average compliance costs around 6% in ad valorem equivalent, undoing the tariff preference (4% on average) for a large number of tariff lines. Administrative costs amount to 47% of the preference margin. These findings are coherent with the view that North–South PTAs could well be viewed like a principal–agent problem in which the Southern partners are just about left on their participation constraint. 相似文献

In-work policies in Europe: Killing two birds with one stone? 总被引:1,自引:0,他引:1
Generous social assistance has been held responsible for inactivity traps and social exclusion in several European countries, hence the recent trend of promoting employment through in-work transfers. Yet, the relative consensus on the need for ‘making work pay’ policies is muddied by a number of concerns relative to the design of the reforms and the treatment of the family dimension. Relying on EUROMOD, a EU-15 integrated tax-benefit microsimulation software, we simulate two types of in-work benefits. The first one is means-tested on family income, in the fashion of the British Working Family Tax Credit, while the second is a purely individualized policy. Both reforms are built on the same cost basis (after behavioral responses) and simulated in three European countries suspected to experience large poverty traps, namely Finland, France and Germany. The potential labor supply responses to the reforms and the subsequent redistributive impacts are assessed for each country using a structural discrete-choice model. We compare how both reforms achieve poverty reduction and social inclusion (measured as the number of transitions into activity). All three countries present different initial conditions, including existing tax-benefit systems and distribution of incomes and wages. These sources of heterogeneity are exploited together with different labor supply elasticities to explain the cross-country differences in the impact of the reforms. 相似文献
