The purpose of this paper is to estimate the duration of unemployment during the period 1967 – 1979 using the concept of a stationary register. The estimate of duration is obtained usingU=iD whereU is stock of unemployed,i is total inflows entering the pool of unemployed andD is duration of unemployment. Both ratio and regression estimates suggest that duration of unemployment has increased from 1.90 months to 4.5 months and this increase cannot be explained entirely by search-turnover views. 相似文献

The worldwide reforming process of pension systems triggered by the demographic transition and globalization has led several countries to implement multi‐pillar pension systems and enhance pension funds. For this reason the studies on the effects that pension funds exert on markets performance have been flourishing in the last decades. In this paper, we provide an updated review of the empirical advances in this field of study, with particular focus on the effects that pension funds produce on labour markets, financial markets and economic growth. 相似文献

The paper investigates whether departures from government borrowing constraints affect the relationship between fiscal-policy innovations and changes in the investment level. ‘Break points’, or apparent departures from present-value budget balance, are then identified. Next, the investment-deficit relationship is examined prior to and following identified break points in an effort to detect potential changes in behaviour. The investment-deficit relationship is quantified by examining posterior coverage bounds of impulse response functions. Britain appears to undergo such a break around 1973. Data from this country suggest that significantly more crowding out occurred following the identified breaks: in contrast, data from other comparison countries that do not appear to have experienced breaks indicate stable investment-deficit relationships. 相似文献

The impact of the ‘green revolution’ on wages has been a contentious issue. This paper uses the cointegration and error correction approach to identify long and short-run relationships between prices, agricultural production and wages of agricultural labourers in Bangladesh, test for homogeneity, test for weak exogeneity with the Johansen-Juselius methodology, test for a structural break, and estimate the long and short-run elasticities of nominal wages with respect to rice prices. We find that agricultural wages have strong positive long run relationships with rice prices, manufacturing wages and agricultural productivity. The short run response of wages, estimated consistently with these longer run relationships, to rice prices is small, highlighting the vulnerability of the rural poor to sudden rises in rice prices, even though in the longer run nominal wages respond sufficiently to rice prices. Policy can promote growth of agriculture and manufacturing but should also mitigate the short run food insecurity of agricultural labourers. 相似文献

We develop a simple model to investigate the possibility that two countries that differ significantly in income levels may be unable to gain from trading with each other. We consider two countries with identical preferences and different technologies. There are two types of goods: one homogeneous, and one quality-differentiated. We show that if one country has an absolute advantage in both types of goods, then no trade may be possible between the two countries, despite differences in relative autarky prices. 相似文献

The purpose of this paper is to examine the behavior of real bilateral exchange rates for major currencies and test the hypothesis of real uncovered interest parity with risk premia, and forward looking expectations. It is plausible that the hypothesis of rational expectations cannot be rejected given the unit root nonstationarity of real exchange rates but it is not unlikely that unit root nonstationarity may be due to rational expectations in foreign exchange markets. 相似文献

We analyze the cost savings potential with regard to administration and management costs by merging Commercial Employment Accident Insurance Funds (Berufsgenossenschaften) in Germany. We use data from the German Federation of institutions for statutory accident insurance and prevention (HVBG) for 1999 to 2004. Large Berufsgenossenschaften (BGs) have lower administration and management costs per insured person. However, costs per insured person are negatively correlated with insured risk of the BGs which in turn is an important source of administration and management costs.Results of a multivariate regression analysis help to identify cost drivers and the existence of economies of scale. Notifiable accidents, occupational diseases and risk explain administration and management costs. All estimation results are highly significant and allow to conclude that remarkable economies of scale are likely to be present in the organization of the BGs. Our results are robust to alternative specifications. Also, risk turns out to be an important cost driver with regard to management costs.A hypothetical policy reform is considered that reduces the number of BGs from formerly 35 to 18. We come up with an estimate of expected cost savings (without cutting benefits) of 83 million euros, about 10 % of the current management costs of the BGs under consideration. 相似文献

Can the small dairy farm remain competitive in US agriculture? 总被引:1,自引:0,他引:1
Smaller dairy farms in the US are observed to have higher costs than larger farms, and whether those higher costs are due to technology or inefficiency has implications for policy to address the small farm. If high cost of production on smaller farms is due to a higher cost frontier, then to make small farms competitive would require research to devise and design technology that is suitable for small farms. If instead high cost is due to inefficiency, then educational approaches are needed to ensure small dairy farms use technology efficiently. To determine the cause of higher costs on small farms, the cost of milk production by farm size was decomposed into frontier and efficiency components with a stochastic cost curve using data on USA dairy farms. Although the frontier cost of production decreases with farm size, that cost reduction is not as pronounced as a cost curve that includes inefficiency. The higher cost of production on many smaller farms is caused by inefficiency rather than technology. 相似文献

Zusammenfassung Eine ?konometrische Studie über die Beziehung zwischen Arbeitslosigkeit und offenen Stellen im Vereinigten K?nigreich. — Dieser
Aufsatz soll zeigen, da\ die stabile Beziehung zwischen echter Arbeitslosigkeit und echten offenen Stellen seit 1966 unterbrochen
ist. Au\erdem sollen die Faktoren untersucht werden, die die Beziehung zwischen echter Arbeitslosigkeit und echten offenen
Stellen bestimmen, wobei einerseits ein ?konometrisches Modell, das auf nichtbeobachtbare Variable besonders eingeht, und
andererseits eine neoklassische Theorie der überschu\nachfrage herangezogen wird. Die allgemeine Hypothese in diesem Artikel
lautet, da\ sowohl die echte als auch die registrierte oder gemessene H?he der Arbeitslosigkeit infolge verschiedener Gesetze
und/oder des Rückgangs der wirtschaftlichen Aktivit?t angestiegen ist. Anschlie\end werden zwei weitere Modelle konstruiert,
um die Rolle der Nachfrage- und Angebotsfaktoren zu analysieren.
Résumé Une étude économétrique sur la relation entre le ch?mage et les vacances en Royaume-Uni. — Le but de cet article est de démontrer que la relation stable entre le vrai ch?mage et les vrais vacances a croulé depuis 1966 et d’analyser les facteurs qui déterminent les relations entre le vrai ch?mage et les vrais vacances en appliquant séparément des modèles économétriques avec des variables inobservables et une théorie néoclassique de la demande d’excès. Notre hypothèse générale est que le montant du vrai ch?mage et le montant du ch?mage régistré ou mesuré augmentaient comme conséquence de la législation gouvernementale et/ou de la baisse de l’activité économique. Finalement, l’auteur construit deux modèles de plus pour analyser le r?le des facteurs de demande et d’offre.
Resumen Un estudio econométrico sobre la relación entre empleo y vacantes en el Reino Unido. — Los objetivos de este artículo son mostrar que la relación estable entre desempleo verdadero y vacantes verdaderas se ha quebrado a partir de 1966 y también analizar los factores subyacentes a las relaciones de desempleo verdadero y vacantes verdaderas separadamente, usando modelos econométricos con variables no observables y una teoría neoclásica de exceso de demanda. Nuestra hipótesis general es que tanto la cantidad verdadera de desempleo y el desempleo registrado o medido creció como consecuencia de la legislación gubernamental y/o la declinación en la actividad económica. Finalmente, formulamos dos modelos adicionales para analizar el rol de factores de demanda y oferta.相似文献

This paper suggests several methods of estimating a technology matrix from a domestic transactions matrix, and a row vector of imports into each sector. The performance of the proposed techniques is assessed on the basis of tests using data on a large number of countries, for which both domestic and technology matrices exist. The best method is subsequently used to generate estimates of technology matrices for countries where such information has not previously been available, and as an illustration of a possible application of such estimates, a brief international comparison of production structures is attempted. 相似文献
