European agri-environmental policy for the 21st century

The present paper reviews the development of agri-environmental policy in Europe and assesses its prospects. While it does so from a predominantly UK perspective, there are many common features of the experience and policy choices across the majority of Member States. The first generation of agri-environmental measures applied command-and-control regulation for the prevention of pollution. Second-generation measures pay farmers for providing environmental public goods. The emphasis on 'amenity' derived from the maintenance of agricultural production systems contrasts with policy approaches in Australia and the USA. Well-designed incentive schemes constitute 'quasi-markets' for public goods, correcting for a pre-existing market failure. Problems in the delivery of policy include poor spatial targeting and a lack of clarity between environmental and income support objectives. Various changes will be required in order to increase the environmental effectiveness and efficiency of agri-environmental mechanisms.     

Financing Decisions along a Firm’s Life‐cycle: Debt as a Commitment Device

We analyse the life‐cycle patterns of a firm’s financing decisions and their interaction with future growth and development decisions. We derive different financing sequences which we link to existing empirical research as well as derive new testable hypotheses regarding differences in firms’ financing decisions to project, firm, market and country characteristics. We provide a rationale for the importance of (external) start‐up debt financing as observed in recent empirical studies. Furthermore, we argue that equity financing at both development stages is more likely for closely‐held firms and in countries in which entrepreneurs face high stigmatisation costs.     

Organic or conventional? Optimal dairy farming technology under the EU milk quota system and organic subsidies

This paper assesses the competitiveness of organic and conventional dairy farms under different milk market and organic farming policy scenarios. We use a DEA-based model to estimate for each policy scenario the sample farms’ profit potential in both technologies. The model enables identification of a farm’s optimal technology based on its input–output observations. The empirical analysis is based on the annual accounts of 1300 Bavarian dairy farms. Results indicate that approximately 69% (78%) of the organic (conventional) farms have chosen their optimal farming system. The remaining organic (conventional) farmers could increase their profit on average by roughly 6% (10%) by switching to the other technology. Abolishment of the EU milk quota results in a considerable decline in the number of sample farms for which organic farming is the optimal technology, suggesting that, ceteris paribus, organic dairy farms may lose competitive advantage with the deregulation of the EU’s milk market regime in 2015. Organic maintenance payments more than double the number of farms with a higher earning potential in organic farming, but their effectiveness could decline when the milk quota is abolished.     

Dynamisierung kapitalgedeckter Altersvorsorge

On the basis of the annual reports of all the life insurance companies covered by the Federal Financial Supervisory Authority (BaFin), the adjustment of payments over the time period 2002 to 2012 is analysed for Germany. The analysis unveils large differences in the adjustment rates of the insurers, not only among companies but also over time. Therefore a steady income stream, a constant income level and the reliability of payments are not ensured for policy holders. In general, the adjustments lead to increasing inequality of income during retirement and rising income heterogeneity in private households. Even worse, these forms of income provision during retirement are not able to compensate for the reduction in the benefit level of statutory old age provision in Germany.     

Divergent regional development, factor mobility, and nontraded goods

Using an endogenous growth model with learning-by-doing effects in the production of a traded good, we derive divergent regional-growth paths in a two-region-three-good setting. A nontraded-goods sector using a mobile as well as an immobile factor of production provides the possibility of a steady-state equilibrium with a dispersed distribution of mobile workers. The paper investigates regional specialization, trade, and migration patterns in the steady-state equilibrium as well as in the transition process towards the steady-state. The long-run production and trade patterns of the regions are determined by history-dependent processes.     

Combining Significance of Correlated Statistics with Application to Panel Data*

The inverse normal method, which is used to combine P‐values from a series of statistical tests, requires independence of single test statistics in order to obtain asymptotic normality of the joint test statistic. The paper discusses the modification by Hartung (1999, Biometrical Journal, Vol. 41, pp. 849–855) , which is designed to allow for a certain correlation matrix of the transformed P‐values. First, the modified inverse normal method is shown here to be valid with more general correlation matrices. Secondly, a necessary and sufficient condition for (asymptotic) normality is provided, using the copula approach. Thirdly, applications to panels of cross‐correlated time series, stationary as well as integrated, are considered. The behaviour of the modified inverse normal method is quantified by means of Monte Carlo experiments.     

Spatial mobility and competition for jobs: Some theory and evidence for Western Germany

This paper sheds new light on the role of regional labor market conditions for regional mobility. We study competition for vacant jobs along two dimensions – between employed and unemployed job searchers, and between resident and non-resident job searchers – within a simple matching framework. Evidence from estimating regional matching functions with data on job searchers disaggregated by previous employment status and regional provenance indicates that competition for jobs along both dimensions affects hiring. Tests of the theoretical predictions suggest that labor market conditions do determine regional mobility, but the countervailing effects of competition between employed and unemployed dilute mobility effects.     

Federal Monetary Policy: A Comment

We comment on an article published in this journal by Hefeker (2003) and reveal an inconsistency in his analysis of monetary policy in federal monetary unions. We clarify an implicit assumption in his model and show that even when this further assumption is met, Hefeker's (2003) claim that a pure majority vote by the regions and the central government results in a monetary authority consisting solely of regionally appointed governors is not generally valid in the context of his model.
