Cost complementarities arise from synergies in the production of heterogeneous goods. It is shown that synergies can be accounted for in terms of shared public inputs (roughly) if and only if synergies decrease as the scope of production increases. This case of “substitutive” synergies is argued to be typical. The key technical tool is a novel interpretation of conjugate Moebius inversion in terms of higher-order differences. 相似文献

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

We investigate how fiscal policies should be designed in Slovenia during the next few years. Using the SLOPOL model, an econometric model of the Slovenian economy, we analyze the effects of different fiscal policies using simulations and determine optimal fiscal policies for Slovenia. We show that the optimal design of fiscal policies is rather close to the austerity course as detailed in the Slovenian Stability Program, revealing the small scope of possible alternative fiscal stabilization policies available due to the relatively low effectiveness of the fiscal instruments with respect to their influence on the business cycle in the Slovenian economy. 相似文献

Intellectual property infringements rank among the top economic crimes, even though there are mechanisms in place to prevent their occurrence. One such mechanism are nondisclosure agreements, which, however, have been reported to fail in practice. This article argues that this may be overcome by strengthening employees’ concept learning. In an experiment, we investigated whether extended nondisclosure agreements, which provide the employee with detailed explanations and examples, lead to better recognition of trade secrets as compared to a standard nondisclosure agreement or no agreement at all. It was found that the extended nondisclosure agreement indeed increased participants’ ability to judge what falls under the trade secret law, whereas the standard nondisclosure agreement showed no such effect. Furthermore, the effects of the factors ‘Involvement’, ‘Specificity’, ‘Publicity’, and ‘Purpose’ on the identification of trade secrets could be proven experimentally. Employees’ judgments of whether an information represents a trade secret seem to rely on general cognitive processes. From this follows that concept learning could be integrated into systematic approaches for protecting intellectual property. 相似文献

The European Commission follows a harmonized approach for calculating structural (potential) output for EU member states that takes into account labour as an important ingredient. This article shows how the recent huge migrants’ inflow to Europe affects trend output. Due to the fact that the immigrants immediately increase the working population but effectively do not enter the labour market, we illustrate that the potential output is potentially upward biased without any corrections. Taking Germany as an example, we find that the average medium-term potential growth rate is lower if the migration flow is modelled adequately compared to results based on the unadjusted European Commission procedure. 相似文献

In this article, we investigate industry momentum strategies. We find that industry portfolios that outperformed in the previous month generate on average significantly higher returns in the holding period than those that underperformed. Plain and risk-managed strategies using this short-run industry momentum are not subject to optionality effects. Also, the tail risks of these strategies are uncorrelated with traditional industry momentum strategies. The spread associated with the risk-managed strategy both meets necessary conditions as a risk factor and is significantly priced in the cross-section of U.S. industry portfolios. 相似文献
