The co-movement of revenue growth across different industries changes over the business cycle. Using a large sample of quarterly
firm revenues, aggregated to industry data from 1969 to 2009, we demonstrate that the correlation is the highest during a
crisis. Our findings of structural changes in correlation have implications for diversification decisions in portfolio analysis
and risk management. The higher correlation in crisis periods increases the downside risk and bankruptcy probability of business
portfolios. We test the hypothesis that average correlations are significantly different, by applying permutation and bootstrap
techniques. As robustness checks, both correlations between industries and the aggregate market and correlations between earnings
confirm our findings. 相似文献

The literature on organizational learning asserts that external learning is often limited geographically and technologically. We scrutinize to what extent organizations acquire external knowledge by accessing external knowledge repositories. We argue that professional service firms (PSFs) grant access to nonlocalized knowledge repositories and thereby not only facilitate external learning but also help to overcome localization. Focusing on patent law firms, we test our predictions using a unique dataset of 544,820 pairs of European patent applications. Analyzing patterns of knowledge flows captured in patent citations, we find that accessing a PSF's repository facilitates the acquisition of external knowledge. As the effect is more pronounced for knowledge that is distant to a focal organization, we conclude that having access to a knowledge repository compensates for localization disadvantages.

The purpose of this article is to model the interaction between the targets of the current Comman Agriculture Politic (CAP): environmental adaptation, subsidies, and efficiency of animal farming. To this end we first have to identify the production frontier and relative efficiency level for each animal‐oriented farm in the sample. The production frontier and efficiency index for each type of farm (assuming no specific production functions) are identified using Data Envelope Analysis (DEA) techniques. We then address the relationship between relative efficiency, farm size, and environmentally friendly behavior by carrying out a nonparametric regression of efficiency, on economic size, a proxy for the degree of environmental appropriateness, and regional dummies. Calculations of the efficiency of the farms including direct subsidies are compared with the counterfactual exercise in the case in which direct subsidies are not considered. Finally, we look for relations between subsidies and factors such as farm size, efficiency, and environmentally friendly behavior. One key result shows that, on average direct payments generally tend to increase efficiency. However, in most of the cases the mean efficiency decreases as the percentage of direct payments rises. Direct payments are found to be positively related to environmentally friendly production, at least in Germany. However, in general, the direct payment system is not sufficient to offset the fact that the less environmentally friendly farms as well as the larger farms are more efficient. 相似文献

This paper is based on the traditional Austrian Theory of Capital which deals with expected values of future returns of investments over various periods of time. The longer the time period that elapses between the beginning of a production process and its end, the higher the (expected) productivity must be due to positive time preferences of individuals. This paper focuses on the uncertainty of future returns and on uncertainty preferences, instead. Based on the Hayekian idea of the dispersion of knowledge in society, it will be shown that there is a systematic relationship between the structure of capital and uncertainty. This result will be derived for a production process characterized by complete vertical integration and one which is not completely vertically integrated. The distinction between these two settings is crucial, if one accepts the distinction between an individual and a social period of production and the planning horizon which are introduced in this paper. 相似文献

Forest management poses particular challenges as the pressure on forests is huge due to deforestation. In this context, the establishment of protected areas is a common conservation measure where institutions are put in place and sanctions regarding forest use are enforced. This paper focuses on the practice of sustainable forest management and the associated perspectives of local institutions at the rainforest margins of Lore Lindu National Park (LLNP) in Central Sulawesi, Indonesia. 相似文献

The development of critical capabilities in foreign subsidiaries: disentangling the role of the subsidiary’s business network 总被引:1,自引:0,他引:1
Within business literature in general, capabilities have advanced to the prime determinant of the corporation’s economic rents. Within international business literature, it is further assumed that multinational corporations can enhance their pool of capabilities through foreign subsidiaries. Foreign subsidiaries are seen as means to assimilate new capabilities from their local, external network and integrate these capabilities into the multinational corporation. Data from more than 2000 foreign subsidiaries shows that some foreign units actually are endowed with superior capabilities which are useful for other corporate entities. It is argued that the development of critical capabilities within these subsidiaries is driven not only by internal corporate actors, but also by external actors. The analysis provides evidence that the role of different internal and external network partners for capability development varies according to the functional activity under consideration. Thus, subsidiaries benefit from various internal and external network actors in very different ways. The contribution ends with some conclusions and some avenues for future research. 相似文献

Credit Constraints in Manufacturing Enterprises in Africa 总被引:2,自引:0,他引:2

We investigate the question of whether firms in Africa's manufacturingsector are credit constrained. The fact that few firms obtaincredit is not sufficient to prove constraints, since certainfirms may not have a demand for credit while others may be refusedcredit as part of profit maximising behaviour by banks. To investigatethis question, we use direct evidence on whether firms had ademand of credit and whether their demand was satisfied in theformal credit market, based on panel data on firms in the manufacturingsector from six African countries. Of those firms with a demandfor credit, only a quarter obtained a formal sector loan. Ouranalysis suggests that while banks allocate credit on the basisof expected profits, micro or small firms are much less likelyto get a loan than large firms. We also find that outstandingdebt is positively related with obtaining further lending. Therole of outstanding debt is likely to be a reflection of inefficiencyin credit markets, while the fact that size matters is consistentwith a bias as well, although we cannot totally exclude thatthey reflect transactions costs on the part of banks. We presentan analysis showing how much more profitable small firms mustbe to obtain a loan than large firms. 相似文献
