"自古燕赵多豪杰",这话一点也不假。我们在曾属燕国辖地的辽河流域采访,不但获悉荆轲、太子丹这样的悲壮豪杰,耶律阿保机、努尔哈赤这样的枭雄,萧太后、孝庄皇后这样的巾帼英雄是辽河人,就连武当山的开山祖、太极拳的创始人张三丰也是辽河人。 相似文献

We investigate whether labor mobility can be a distinct source of growth by studying the productivity impact of business visits (BVs), vis-à-vis that of other well-known drivers of productivity enhancement. Our analysis uses an unbalanced panel—covering on average 16 sectors per year in ten countries during the period 1998–2011—which combines unique and novel data on BVs sourced from the US National Business Travel Association with Organization for Economic Cooperation and Development (OECD) data on R&D and capital formation. We find that mobility through BVs is an effective mechanism to improve productivity, being about half that obtained by investing in R&D. This relevant finding invites viewing short-term mobility as a strategic mechanism and prospective policy tool to overcome productivity slowdowns and foster economic growth. 相似文献

This paper is an assessment of the impact of child support enforcement and welfare policies on nonmarital teenage childbearing
and motherhood. We derive four hypotheses about the effects of policies on nonmarital teenage childbearing and motherhood.
We propose that teenage motherhood and school enrollment are joint decisions for teenage girls. Based on individual trajectories
during ages 12–19, our analysis uses an event history model for nonmarital teenage childbearing and a dynamic model of motherhood
that is jointly determined with school enrollment. We find some evidence that child support policies indirectly reduce teen
motherhood by increasing the probability of school enrollment, which, in turn, reduces the probability of teen motherhood.
This finding suggests that welfare offices may wish to place greater weight on outreach programs that inform more teenagers
of the existence of strong child support enforcement measures. Such programs might reduce nonmarital teen motherhood further
and thus reduce the need for welfare support and child support enforcement in the long run.

本文运用多案例研究方法,选取四家重庆摩托车企业的八次对外直接投资案例,对企业能力、竞争强度如何影响企业对外直接投资动机的形成进行了探讨.研究发现,我国摩托车企业的对外直接投资动机主要表现为寻求海外市场.当企业不具备技术相关能力和市场相关能力的相对优势,面临竞争者增多、价格竞争增强的情况时,企业容易产生防御型市场寻求的对外直接投资动机,并且如果主要竞争者已在目标市场投资,更容易促发企业形成这类动机.当企业具备技术相关能力和市场相关能力的相对优势,同时又面临竞争者增多、价格竞争增强的情况时,企业容易产生进攻型市场寻求的对外直接投资动机,并且如果主要竞争者尚未在目标市场投资,更容易促发企业形成这类动机. 相似文献

This paper aims to analyse “how” and “why” a company engages in CSR and sustainability. The “how” concerns the features of the firm’s CSR and sustainability approach, defined in terms of a firm’s strategy (implemented issues, initiatives and activities) and organization (organizational structures and roles and managerial systems adopted). The “why” refers to the key determinants, both internal and external, of CSR and sustainability. Finally, how the firm’s CSR and sustainability approach evolves over time and the relation between CSR determinants in various stages of the CSR evolutionary path are also investigated. The research method is based on the longitudinal analysis of a case study concerning a large multinational company operating in the telecommunications industry in Europe. The analysis of the case study shows that sub-cultural differences in the approach to CSR and sustainability may occur across hierarchical levels and functional units. Moreover, embedding CSR and sustainability principles doesn’t follow a linear and continuous process, made by sequential stages. Indeed, it can be characterized by an up and down evolutionary path, based on different stages with a changing emphasis given to CSR and sustainability issues. Finally, we find that the firm CSR and sustainability approach is not an autonomous choice, but it is a consequence of the contingent role played by both the external and the internal drivers and by their relative importance during the company’s CSR history. 相似文献

Explaining the demand for structured financial products: survey and field experiment evidence 总被引:1,自引:0,他引:1
In many countries structured investment products are popular among retail investors. We explain the demand for these products
using unique field data where we let subjects freely design their “favorite” structured product. Results suggest that the
supply with capital protected products (guarantee certificates) might indeed be demand-driven. This does not seem to be the
case for other product categories where marketing and sales practices might play a more important role. In a survey among
financial practitioners we find furthermore that a demand for capital protected products can be explained by loss aversion
and saving motifs, e.g. for buying a house. 相似文献

This paper examines the quality of the relationship between business managements and works councils in small and medium-sized enterprises and strives for answering the question, which factors determine the quality. As ownership is an important determining factor of the establishment of works councils in small and medium-sized businesses, especially the impact of ownership on this relationship has been investigated. Agency theory and stewardship theory give hints that the owner management can have different impacts on this relationship. In order to test these contradictory hypotheses we have estimated a Heckman selection model to investigate which factors determine the quality of the relationship between business managements and works councils. Our results based on data generated from a survey in small and medium-sized enterprises conducted by the IfM Bonn in the years 2005 and 2006 indicate that ownership has a negative influence on the establishment of works councils, but a positive one on the quality of the relationship between business management and works council. Thus, the hypotheses predicting the existence of stewardship behaviour among owners and the existence of agency behaviour among managers can be confirmed. 相似文献

This paper provides a signaling explanation for benefits of conservative accounting in a debt contracting setting. It develops a model in which firms want to finance more or less risky projects through debt, which is private information. Creditors price the risk on average riskiness, which implies a relatively high interest rate for low-risk firms. These firms can signal their low-risk type by implementing a conservative accounting system. The accounting signal is used in a debt covenant that stipulates early repayment in case of a bad signal. Thus, the low-risk firms benefit from a lower interest cost, but at the cost of higher risk of being forced to liquidate a profitable project. The analysis establishes conditions for separating and pooling equilibria and determines their individual and social welfare implications. It shows that conservative accounting by low-risk firms can even increase social welfare if it mitigates underinvestment. 相似文献
