The present paper studies the equilibria of a simple overlapping generations model of pure exchange in which money is traded. There is a continuum of agents in each generation and population growth is endogenous via voluntary decisions on children. Any monetary steady state has to satisfy the golden rule that the interest rate equals the growth rate. Still such a monetary steady state may be inefficient. If raising children is not excessively profitable, then there exists a transfer scheme, in favor of those who raise children, which improves upon the steady state. 相似文献

Technology management research appears to have a much longer history than is commonly assumed. In this short paper attention is drawn to some of Francis Bacon's writings which appeared in the early seventeenth century, and which contain ideas on laboratory organization that still have relevance today. In fact, it is only recently that the same broadness of laboratory functions described in the earlier text has been re–discovered. 相似文献

In this paper, we analyze the influence of hedging with forward contracts on the firm's probability of bankruptcy (POB). The minimization of this probability can serve as a substitute for the maximization of shareholders' wealth. It is shown that the popular minimum variance hedge is generally neither necessary nor sufficient for the minimization of the firm's POB. Moreover, our model suggests a correction of the widespread view that a reduction in the variance of the future value of the firm is inevitably accompanied by a reduction in its default risk. We derive an analytical solution for the variance-minimizing hedge ratio of a firm exposed to both input and output price uncertainty that takes into account the issue of correlation. Based on this solution, we provide a graphical analysis to prove our claim that there is a fundamental difference between hedging policies focused on bankruptcy risk and those following conventional wisdom even if positive correlation constitutes a “natural” hedge. 相似文献

Win-Win situations are used and also created by companies which cooperate with each other, complement each other on a synergy basis and work together fairly and competently. Today, business partnering has therefore become a key qualification for companies. This should not depend alone on the commitment of individual persons.This article describes how Siemens has organized its company, services and products using partnering solutions and how it has installed this concept as an intrinsically dynamic process. Thanks to institutionalized partnering, B2B interfaces have been established to form a rational alliance, offering benefits to all involved, and can be used regardless of the size of the company. These offerings generate Win-Win situations themselves—and provide individual employees in large companies with a structural framework for a personal partnering initiative. 相似文献

Herausforderndes Verhalten bei Demenz - Wenn Aggression, erh?hter Bewegungsdrang, starke Orientierungsprobleme, Selbst- und
Fremdgef?hrdung oder andere „herausfordernde“ Verhaltensweisen auftreten, wird die Pflege und Begleitung von Demenzkranken
als Belastung erlebt. Doch Pflegende stehen dem Problem nicht hilflos gegenüber. Eine interdisziplin?re Expertengruppe gibt
mit ihren Empfehlungen ein Handlungsgerüst. 相似文献

This contribution investigates the efficiency of water suppliers in rural areas of East and West Germany. A non-radial measure
of input specific allocative inefficiency is used to reduce the distributional dependency with respect to the inefficiency
parameters. It is based on the demand system of a flexible cost function for the variable inputs labour, energy and chemicals
modelled by applying a modified symmetric generalized McFadden functional form. Concavity restrictions, as required by economic
theory, are imposed. The analysis reveals that efforts towards increasing suppliers’ allocative efficiency should focus on
the relatively inefficient usage of the input chemicals. The input specific allocative model specification was found to be
superior to the overall allocative specification.

One of the main goals of the European Union, laid down, inter alia, in the Lisbon Strategy and in the “Europe 2020” Strategy, is to raise employment. One important means of supporting the
creation of new jobs is to increase competition. In this paper, it is shown that on average the mark-up, i.e. the deviation
of prices from marginal cost in the euro area still exceeds the levels observed in the UK and in the US. After completion
of the Single Market Programme in 1993, the mark-up has declined in the euro area and even more in the UK. Nevertheless, there
is a strong cross-country variation between Member States, with a particularly high mark-up ratio found for Italy. Panel estimations
show that total factor productivity growth, labour productivity growth and the labour market performance in the euro area
could be improved by reducing the mark-up. This could be achieved by a proper institutional design. More competition could
indeed improve the macroeconomic performance. 相似文献
