On the Determinants of Mandatory Works Councils in Germany

German works councils are often thought of as operating in all firms that exceed the basic size threshold (of five permanent employees) established under law. Drawing on a new large-scale, representative German data set, we report that only one-fifth of firms in our sample have works councils even if such firms do account for almost three-fourths of employment. The principal factors behind works council presence emerge as fairly conventional: firm size, firm age, branch plant status, the gender composition of the work force, and certain working arrangements. There are also signs of a close relation between workplace union density and council presence. However, some controversial causal links suggested in an earlier econometric literature receive little support.     

Versicherungsmedizinische Risikobeurteilung von pathologischen Leberwerten und aktuellen Entwicklungen bei der chronischen Hepatitis

Alcoholic liver disease, non alcoholic fatty liver and chronic viral hepatitis have a high prevalence in the German population. They are associated with significantly increased occupational disability and mortality. Elevated levels of GGT or ALT can be found in about 10 % of the general population. Attempts to identify an underlying diagnosis often remain unsuccessful. In selected cases CDT can be helpful to confirm or rule out suspected alcohol-abuse. Recent studies showed that non alcoholic steatohepatitis (NASH) is a potentially severe complication of diabetes and its metabolic precursors. Treatment options for chronic viral hepatitis get more and more sophisticated, but the rates of sustained cure are still unsatisfactory, especially in hepatitis B with negative HBe-antigen and the hepatitis C genotypes 1, 4 and 5. Life long suppression of HBV replication by nucleoside analogues seems to prevent liver cirrhosis, but may become a great burden on health costs. The risk assessment of HBV carriers and of patients with successfully treated viral hepatitis should rely on the expertise of experienced physicians.     

Factors Affecting Technical Efficiency among Coffee Farmers in Côte d’Ivoire: Evidence from the Centre West Region

This paper presents measures of technical efficiency for a sample of 81 peasant farmers in the low‐income region of Côte d’Ivoire. DEA techniques were used to compute farm‐level technical efficiency (TE) measures. The analysis reveals average levels of technical efficiency equal to 36 per cent and 47 per cent respectively for the CCR ( Charnes et al., 1978 ) and BCC ( Banker et al., 1984 ) models. These results suggest that substantial gains in output and/or decreases in cost can be attained given existing technology. In a second step analysis, two‐limit Tobit regression techniques were used to examine the relationship between TE and various farm/farmer characteristics. From a policy point of view, an important conclusion stemming from the analysis of our sample is that family size, membership to farmer's club or association and the origin of the farmer are the variables found to be most promising for action. The analysis suggests that policymakers should foster the development of the formal farmers’ club or association by building the capacity of the farmers. Our analysis also supports the argument for public sector involvement in the provision of information on labour force management to peasant farmers as a means to improve efficiency levels, and thus household incomes.     

Aktuelle Entwicklungen in der Beaufsichtigung und Rechnungslegung von Versicherungsunternehmen: IFRS und Solvency II

Accounting and supervision are closely related, especially via the determination of regulatory capital. As a precondition for the harmonisation of solvency rules within Europe, as discussed in the context of Solvency II, there is a need for harmonised accounting rules regarding the recognition and measurement of assets and liabilities. The International Financial Reporting Standards resp. International Accounting Standards (IFRS resp. IAS) are used as a starting point. Insurance contracts are accounted for under IFRS 4, published in March 2004, which is only established as an interim standard allowing insurance companies to continue their existing accounting policy without major changes in their accounting systems. The IASB has just begun working on a final standard (Phase II). The IASB’s work on the final standard should be taken into account for the determination of regulatory capital as well. The third pillar of Solvency II is an additional connection between international accounting standards and the Solvency II project: extensive disclosure requirements companies shall provide disciplinary transparency with regard to their risk management systems and risk profiles.     

Estimation of demand and supply functions from univariate sample with known separation

It is shown that the joint unconditional density function of demand and supply is a computable function of parameters of the conditional density function of the observed quantity. Propositions of formulating unconditional and conditional disequilibrium measures are suggested.     

Aid to Agriculture, Growth and Poverty Reduction

Agriculture and rural growth promotion show a recent 'comeback' in development cooperation, but action on the ground so far is not sufficient. After years of neglect, policy makers have recognized that poverty reduction in many low income countries can only be achieved if development efforts are clearly focused on the sector which employs most of the poor, and the space where most of the poor live. The importance of agricultural growth was amply demonstrated during the economic transformation of Asia. Forty years ago, Asia was a continent of widespread poverty. Today, most Asian countries are experiencing significant growth and poverty reduction. Rapid growth in productivity in the small-farm sector helped drive this process. Sub-Saharan Africa, however, failed to achieve rapid agricultural growth and remains mired in poverty and hunger. If Africa is to halve poverty by 2015 in accordance with the Millennium Development Goals (MDG), agriculture will need to maintain an annual growth rate of 6 per cent between 2000 and 2015. China's experience from 1978 to 1984 shows such growth is possible. Achieving the desired rapid rates of growth in Africa will require coherent policies by governments and donors, a substantial investment of public resources in rural infrastructure and access to agricultural technology, and significant improvement in national governance.
