We assess the contribution of European authors to 10 topjournals of economics from 1980 to 1998. Despite efforts on the European Union and national levels topromote academic excellence, European authors still play a minor role in top journals. Examining the development overtime we find little evidence for an increasing share of European contributions. Particular attention has been paidto the educational background of European authors. There is still a segmentation of academic education alonglanguage barriers in continental Europe. However, a considerable proportion of European authors has received a PhD from the US. 相似文献

Coping with Technological Change: The Role of Ability in Making Inequality so Persistent 总被引:1,自引:0,他引:1
This study provides an explanation to the evolution of wage inequality over the last 30 years and supports this explanation with evidence. A faster rate of technological progress introduces new unknown elements at the workplace. The need to cope with the unknown accentuates the role of ability and thus increases wage inequality within and between education groups. Inasmuch as education is an irreversible investment project the rise in within group inequality BOOSTS UP the rise of between group inequality. Guided by this theory we turn to the PSID for evidence. Using parents' education to approximate child's ability we show the following set of results: (a) Controlling for education of the child, parents' education contributed much more in the 1980s to his wage growth than in the 1970s. (b) The correlation between the parents' and the child's education increases from the 1970s to the 1980s. (c) The return to college education for an individual with no ability rents did not change—it remains steady at the 23 percent. (d) Facts (a)–(c) CANNOT be attributed to the impact of parent's income. It is parents' education and not parents' income that is more relevant for son's economic outcomes in the 1980s. 相似文献

In the last 10–15 years a lot of attempts has been devoted to study the calssical process of convergence of market prices toward natural prices. The two forces that one has thought could achieve this target were capital mobility, that determines the dynamics of output, and demand-supply forces, that determine the dynamics of prices. In this article a model of classical competition is proposed in which a full-cost pricing mechanism is adopted in the rule of evolution of market prices. An asymptotical stability result of long-run equilibrium is proved for a two-commodity model with and without a final demand. 相似文献

Most of the literature on transboundaryenvironmental problems treats population ineach country or region as constant, ignoringpopulation mobility. We showed previously thatif there is perfect population mobility betweenregions, and populations are homogeneous, asocially efficient outcome can be supported asa Nash equilibrium of the game of uncoordinatedpolicy setting, even without any internationalenvironmental agreement. In the present paperwe introduce heterogeneous population, and showthat when people differ, a non-cooperativeoutcome is generally inefficient. We alsodemonstrate that for a particular set ofobjective functions for the regionalgovernments, there is an equilibrium of thegame of uncoordinated policy setting that isefficient. Finally, we give an example wherethe decentralized outcome is efficient whenthere is no population mobility, butinefficient when there is population mobility. 相似文献

Capital Mobility, Agglomeration and Corporate Tax Rates: Is the Race to the Bottom for Real? 总被引:1,自引:0,他引:1
Based on a data set for 19 OECD countries for the period 19812001,we estimate the impact of FDI on corporate tax rates, wherechanges in FDI are a measure for changes in capital mobility.So far the literature has been concerned with the related butrather different question as to the sensitivity of FDI to taxrates. Our article takes an opposite perspective and asks whatthe impact of capital mobility is on corporate tax rates. Indoing so, we explicitly take the role of agglomeration intoaccount. In theory, core countries can afford a higher tax ratecompared to peripheral countries. In our estimation strategy,we instrument capital mobility to deal with reverse causality.The main conclusion is that increased international capitalmobility, measured by FDI flows, implies a lower corporate taxrate. But we also find that agglomeration matters: core countrieshave a higher corporate tax rate than peripheral countries.If there is a race to the bottom, it seems that it is more realfor some countries than others.

会计师事务所的进入、退出与审计市场的竞争 总被引:3,自引:0,他引:3
本文主要从进入、退出的角度研究审计市场的竞争。本文的分析表明,审计市场的市场占有率变动率更为合理地衡量市场的动态变化,审计市场的进入壁垒主要是准入壁垒(管制壁垒),而结构性壁垒和流动性壁垒主要存在于大客户市场,对于小客户市场的影响作用很小。为了防止进入者的进入,在位者通过各种流动性壁垒的设置以提高进入者的成本。但从总体看,审计市场仍然是高度竞争的。 相似文献

In a two-country model with mobile capital we analyse decentralized social insurance policies. These policies are a compromise between the preferences of workers and capital owners. Due to wage bargaining, worker-based social insurance contributions are borne by capital owners. These contributions affect the profitability of investment, and consequently the direction and size of capital flows. Countries will take account of these effects in determining social insurance policy. Noncooperative decision making results in tax competition and an underprovision of social insurance. In addition, increasing economic integration, represented by increasing capital mobility, could imply a divergence of social insurance levels in the two countries. 相似文献

This paper describes the frameworks and cognitive tools that have been developed to enhance practising teachers' pedagogical
content knowledge in primary school technology education. The frameworks evolved from our research that firstly examined existing
teaching practices, secondly enhanced formative interactions and thirdly enhanced summative assessment strategies. The evidence
gained over the three years demonstrated how the effective use of frameworks could be utilised to enhance teacher pedagogical
content knowledge (PCK). How we see learning is of prime importance in examining the development of teacher pedagogical content
knowledge. A sociocultural view of learning is taken where human mental processes are situated within their historical, cultural
and institutional setting. In the research project we strongly emphasised the need for teachers to build a knowledge base
for teaching technology. Critical aspects identified as enhancing PCK included: negotiated intervention, planning frameworks,
reflection on case studies, workshops and support in classrooms, appropriate resources, teacher agreement meetings, portfolios
of student work and summative profiles. The increased PCK resulted in: enhanced teacher knowledge about technology including
the nature of technology, areas of technology and specific technological knowledge, changed pedagogical approaches, enhanced
teacher student interaction, refinement of appropriate learning outcomes, critical decision making, improved teacher confidence,
and enhanced student learning. Seven characteristics or features of pedagogical content knowledge that we believe are important
for effective teaching and learning in technology are presented.
