French unemployment: a transatlantic perspective 总被引:1,自引:0,他引:1
The paper compares the French and US labour markets. It shows that differences in unemployment rates are especially acute for young and old workers, but appear to be negligible for middle-aged workers. All French workers, however, experience job flows that are quite distinct from their American counterparts as they are exposed to long spells of infrequent unemployment, which is the opposite to the US case. Critical differences across ages and skills regarding the patterns of exit from and entry into employment are also displayed. The paper dispels the view that these differences originate from the behaviour of the unemployed (or the set of institutions that guide their decisions), and that this is new to the French labour market. 相似文献

We determine the optimal exploitation time-paths of two energy resources, one being depletable and polluting, namely a fossil fuel, the other being renewable and clean. These optimal paths are considered along with the two following features. First, the cumulative atmospheric pollution stock is set not to exceed some critical threshold and second, the polluting emissions produced by the use of fossil fuel can be reduced at the source and stockpiled in several carbon sinks of limited capacity. We show that, if the renewable resource flow is abundant, the optimal path requires that sequestration is implemented only once the ceiling is reached. Moreover, the reservoirs should be completely filled by increasing order of their respective sequestration costs. 相似文献

Economic activity accelerated in the United States, in the second part of the cycle, after 1995, within an environment of decreasing inflation. France has followed a qualitatively similar path since 1997, also clearly suggesting the effects of a positive supply shock. The spread of new information and communication technologies (NICT) partly explains these singular events. On one hand, a calculation of contributions to output growth suggests that they would explain about half of the increase in activity in the United States and one-fifth in France. On the other hand, a trend/cycle decomposition reveals that the structural acceleration in output and productivity gains in the United States are very much restricted to industries producing NICT and there is a rather small break in productivity gains. In France, where differences between sectors are not so clear-cut, the diffusion of NICT has been accompanied by a slowdown in trends in productivity gains. In both cases, there is little room left for the effects of the diffusion of technical progress associated with NICT. 相似文献

The influence of the past price behaviour on the realized volatility is investigated, showing that trending (driftless) prices lead to increased (decreased) realized volatility. This ‘volatility induced by trend’ constitutes a new stylized fact. The past price behaviour is measured by the product of two non-overlapping returns (of the form r × L[r] where L is the lag operator), and is different from the usual heteroskedasticity. The effect is studied empirically using USD/CHF foreign exchange data, in a large range of time horizons. On the modelling side, a set of ARCH based processes are modified in order to include the ‘volatility induced by trend’ effect, and their forecasting performances are compared. The aim is to understand the role and importance of the various terms that can be included in such a model. For a better forecast, it is shown that the main factor is the shape of the memory kernel (i.e. power law), and the next most important factor is the trend effect. The subtle role of mean reversion is also discussed. 相似文献

This paper examines credit policy stress in the West African Economic and Monetary Union and provides evidence that a regional credit policy would not suit all the countries that are members of this currency union. Some countries obtain a higher volume of domestic credit when policy is conducted at a domestic level than they would in the context of a single regional policy. Furthermore, there are differences in the country‐specific reaction function to changes in the economic environment. To show the inappropriateness of a regional credit policy within the West African Economic and Monetary Union area, we compute credit stress indicators both for the countries and for the region taken as a whole. The stress indicators represent the gap between the optimal policies conducted at country and regional levels. Our study covers the period from 1980 to 2007. 相似文献

Carl Menger, who became regarded as the founder of the Austrian School, did not only confront the German Historical School
and criticize British Classical Political Economy, he also read the French Liberal economists. The link between Say and Menger
has already been asserted, but on an intuitive basis. It seemed necessary to give substantial proof of its true extent, as
well as to document it with proper archival work—that is done in the present article. Menger’s reading of other French authors:
Count Pellegrino Rossi, who succeeded Say at the Collège de France, Michel Chevalier, a major name of the French Industrialization,
Frédéric Bastiat, the famous defender of free-trade, is less known. It is also documented here, bringing to light first-hand
material, mainly from the Menger Collection located in Japan, and the Perkins Library at Duke University. Thus are acknowledged
the origins of Menger’s thought in French liberal economists.

This paper designs a horizontal indicator‐based assessment methodology aimed at identifying those EU countries presenting a potential need and scope for shifting taxation away from labour to other tax bases less detrimental to growth. The assessment methodology, as a first step, selects a set of indicators measuring specific aspects of tax policy. Subsequently, for each individual indicator, performance thresholds are calculated based on a benchmarking approach. Finally, a screening algorithm based on commonly accepted findings from the relevant economic literature is used to assess the overall performance of a country in two policy areas, namely the need for a tax shift and the scope for it. Various robustness checks are performed. 相似文献
