A buyer’s technical knowledge may increase the efficiency of its supplier. Suppliers, however, frequently maintain relationships
with additional buyers. Knowledge disclosure then bears the risk of benefiting one’s own rival due to opportunistic knowledge
transmission through the common supplier. We show that in one-shot relationships no knowledge disclosure takes place because
the supplier has an incentive to transmit and, anticipating that, buyers refuse to disclose any of their knowledge. In repeated
relationships knowledge disclosure is stabilized by larger technological proximity between buyers and suppliers and destabilized
by the absolute value of the knowledge.

There is a rising political discussion in Germany around abolishing the final withholding tax on capital income. The German tax reforms that introduced this tax lowered tax rates, in particular on interest income. According to some authors, the growing inequality of income and property is a strong argument for the higher taxation of capital income. However, other authors argue that the neutrality aspects concerning private investment are inadequate. An abolishment of the final withholding tax would not solve these problems and, moreover, would turn back the achieved improvements. Therefore, the German Council of Economic Experts suggests complementing the previous reforms by introducing an allowance for corporate equity. 相似文献

In the summer of 2014 Germany will witness the most substantial expansion of pension expenditures since the 1950s. Yet, while this reform package was motivated mainly by the dismal prospect of rising old age poverty rates, it does little to alleviate this problem. On the contrary, its two central elements, an expansion of the pension claims of mothers whose children were born before 1992, and access to early retirement at age 63 for workers with a long insurance history, tend to benefit rather privileged groups of the insured. These measures endanger the sustainability of the German pension system and will necessitate future generations to work even longer than would have been the case otherwise. 相似文献

The partial correlation is a commonly used measure for assessing the bivariate correlation of two quantitative variables after eliminating the influence of one or more other variables. The partial correlation is generally interpreted as the correlation that would result if the variables to be eliminated were fixed (not allowed to vary and influence the other variables), which is referred to in the statistical literature as conditional correlation. The present paper demonstrates, by means of theoretical derivations and practical examples, that when the assumption of multivariate normality is violated (e.g., as a result of nonlinear relationships among the variables investigated) the usual interpretation of the partial correlation coefficient will be basically incorrect. In extreme cases the value of the partial correlation coefficient may be strongly positive, close to 1, whereas the conditional correlation may have a large negative value. To solve this problem the paper suggests to partial out a certain function (in most cases the square) of the variables whose effects are to be eliminated if nonlinear relationships are likely to occur. 相似文献

Abstract Today, many public professionals feel estranged from the policy programmes they implement; that is, they experience ‘policy alienation’. This is of concern as, for satisfactory implementation, some identification with the policy is required. We conceptualize policy alienation based on the sociological concept of work alienation, and show how this can be used in policy implementation research. Studying a Dutch case of professionals implementing a new work disability decree, we observe how NPM practices increase policy alienation because of a perceived dysfunctional focus on efficiency and results. A large number of policy changes and stricter implementation rules further increased policy alienation. 相似文献
