The allocation of regional policy funds varies dramatically across regions even when one controls for regional development indicators. We investigate the impact of local government performance as well as spillovers in knowledge, financial means and social relations as determinants of regional fund absorption. Government performance is derived within a Data Envelopment Analysis approach. Spillovers are investigated using a spatial Durbin model. Results show that government performance has a positive impact on fund absorption. Spillovers occur in knowledge as well as in financial means. The empirical analyses focus on Special Accession Program for Agriculture and Rural Development in Slovakia using panel data.  相似文献

Eastern Germany and the Conflict between Wage Adjustment, Investment, and Employment: A Numerical Analysis. — In this paper, some light is shed on the dynamics of the adjustment process in eastern Germany by studying the linkages between the dynamics of wage adjustment, investment, and employment. An extended dynamic investment model, which includes adjustment costs for capital and revision costs for investment, is presented. This model is specified according to the east German economy and analyzed numerically by an optimization method based on direct collocation. Results are obtained for the time horizon of adjustment and for the implications of different wage strategies on the path of investment and employment.  相似文献

This paper examines the impact of trade policy on specialization patterns in ten Latin American countries over the period 1985–1998. These countries are natural case studies because in the last decades they implemented comprehensive trade liberalization programs, both generally and preferentially, starting from relatively high tariff protection levels. Our econometric results suggest that reducing own most favored nation tariffs is associated with increasing manufacturing production specialization. Furthermore, we find that preferential trade liberalization and differences in the degree of unilateral openness have resulted in increased dissimilarities in manufacturing production structures across countries. These results are robust across specialization measures and estimation methods.

Since Sen's insightful analysis of Arrow's Impossibility Theorem, Arrow's theorem is often interpreted as a consequence of the exclusion of interpersonal information from Arrow's framework. Interpersonal comparability of either welfare levels or welfare units is known to be sufficient for circumventing Arrow's impossibility result. But it is less well known whether one of these types of comparability is also necessary or whether Arrow's conditions can already be satisfied in much narrower informational frameworks. This note explores such a framework: the assumption of (ONC + 0), ordinal measurability of welfare with the additional measurability of a "zero‐line", is shown to point towards new, albeit limited, escape routes from Arrow's theorem. Some existence and classification results are established, using the condition that social orderings be transitive as well as the condition that social orderings be quasi‐transitive.  相似文献

In this paper we consider a risk process in which claim inter-arrival times have a phase-type(2) distribution, a distribution with a density satisfying a second order linear differential equation. We consider some ruin related problems. In particular, we consider the compound geometric representation of the infinite time survival probability, as well as the (defective) distributions of the surplus immediately prior to ruin and of the deficit at ruin. We also consider explicit solutions for the infinite time ruin probability in the case where the individual claim amount distribution is phase-type.  相似文献

Using survey forecasts of a large number of Asian, European, and South American emerging market exchange rates, we studied empirically whether evidence of herding or anti‐herding behavior of exchange‐rate forecasters can be detected in the cross‐section of forecasts. Emerging market exchange‐rate forecasts are consistent with herding (anti‐herding) if forecasts are biased towards (away from) the consensus forecast. Our empirical findings provide strong evidence of anti‐herding of emerging market exchange‐rate forecasters.  相似文献

The controversy around fixed-term contracts centres around the conflict between the employer’s need for flexibility and the employee’s need for security. The authors propose flexible contributions for employers to the public unemployment insurance system to balance both interests. The employers’ contributions for their temporary staff would increase while the contributions for their permanent staff would in turn decrease slightly. The authors calculate four versions. With regards to the total sum of contributions, the first version holds the contributions received constant while the second version leads to a reduction. They then repeat these two calculations for fixed-term contracts without substantive grounds. The flexibility premium takes into account the higher unemployment risk of employees with fixed-term contracts and establishes monetary incentives for employers to hire employees with permanent contracts.  相似文献

Das Soziale Internet (Web 2.0) macht jeden potenziell zum Kommunikator — die Agenda-Setting-Funktion verlagert sich von den Massenmedien zu den Teilnehmern Sozialer Netze. Damit sehen sich Unternehmen einer zunehmend vielf?ltigen, selbstbewussten und kritischen ?ffentlichkeit gegenüber. Um Nachhaltigkeit glaubhaft zu kommunizieren, sollten Unternehmen sich daher als dialogbereiter Gespr?chspartner in Sozialen Netzen etablieren. Der vorliegende Beitrag leitet aus aktuellen Beispielen vier Spielregeln für die CSR-Kommunikation im Web 2.0 ab.  相似文献

It is shown that vectors ( S M 1 , … , S Mn ) and ( S' M'1 , …, S' M'n ) of random sums of positive random variables are stochastically ordered by upper orthant dependence, lower orthant dependence, concordance or by the supermodular ordering whenever their corresponding random numbers of terms ( M 1 , … , M n ) and ( M' 1 , … , M' n ) are themselves ordered in this fashion. Actuarial applications of these results are given to different dependence structures for the collective risk model with several classes of business.  相似文献
