A household model with differential asset endowments and idiosyncratic transactions costs in accessing labor markets is developed to (1) explain membership of farm households to alternative labor regimes (sellers, employers, or self-sufficient in labor), (2) test for recursivity between production and consumption decisions selectively by labor regime, and (3) identify the determinants of differential labor productivity across labor regimes. The model is applied to a 1994 household survey of the Mexican land reform sector. 相似文献

Zusammenfasung YOGA bei Gesundheitsproblemen — Yoga bietet viele übungen, die den unteren Rücken, Bauch und Oberschenkel st?rken, dabei Haltung
und Aussehen verbessern und Kraft und Selbstvertrauen aufbauen. Und anstatt über Problemzonen zu lamentieren und zu (selbst)kritisch
zu sein, ist es allemal besser, seine Energie ins üben zu stecken. 相似文献

Financing entrepreneurship: Bank finance versus venture capital 总被引:5,自引:0,他引:5
This paper examines the entrepreneur's choice between bank finance and venture capital. With bank finance, the entrepreneur keeps full control of the firm and has efficient incentives to exert effort. With venture capital finance, there is a two-sided moral hazard problem as both the entrepreneur and venture capitalist (VC) provide unverifiable effort. The entrepreneur benefits from the VC's managerial input but must surrender partial ownership of the venture, thus diluting the entrepreneur's incentive to provide effort. Venture capital tends to be preferred to bank finance when VC productivity is high and entrepreneurial productivity is low. 相似文献

How do country‐level governance characteristics impact the relationship between R&D and firm value? 下载免费PDF全文
This article addresses the question of how country‐level governance characteristics moderate the market valuation of research and development (R&D). Using a valuation model and panel data from companies in the European Union, United States, and Japan, we find that effective corporate governance allows the market to better assess a firm's R&D investments. This finding is the conjunction with the effect of the legal system, the financial system, and mechanisms of control. First, as effectiveness of investor protection increases, the market valuation of R&D projects also increases. Second, more developed financial systems do a better job assessing R&D. Third, effective control mechanisms reinforce the positive effect of R&D on a firm's market value. In sum, our findings shed light on how policymakers can increase the benefits from firms' R&D spending and thus foster economic growth and social welfare using these country‐level governance characteristics. 相似文献

- The topic of donations is one of high relevance and has been widely covered in contemporary marketing literature. It is a topic of interest to both theoreticians and practitioners alike, particularly due to its implicit links to fundraising activities and research. The reality of what makes an individual donor ultimately part with his money and give it away to a nonprofit organization is a hot contemporary topic. This study looks into the role of religiosity as a predictor of donations practices. Also volunteerism and compassion, two acts of pro‐social behaviour are analysed as predictors of donations practices. Using data collected from a survey of 612 charity donors in Portugal, the results show unequivocally that religiosity does influence donations practices, and so being a predictor of donations practices. Moreover, pro‐social behaviour is a predictor of donations practices when in the case of volunteerism, but not in the form of compassion.
- The findings are particularly useful for nonprofit organizations that want to attract and retain individual charitable donors and may also help to increase donation regularity, to obtain higher amounts, and donations both to religious and to secular organizations. Finally, it can be stated that the understanding of religiosity sheds light on knowledge about donations practices, and that this study also makes an important contribution to academia, as it is the first study conducted in Portugal that assesses the drivers of donations practices.

During episodes of increased global risk aversion, or risk‐off episodes, safe haven currencies such as the Swiss franc tend to appreciate. The immediate impact of a risk‐off shock is an increase in net private inflows to Switzerland, mostly driven by a reduction in Swiss residents’ net purchases of foreign debt securities and reduced foreign exposure by Swiss banks. Given that the bulk of capital movements related to risk‐off episodes is driven by decisions of Swiss residents, capital flow management policies that discriminate based on the residency of the investor (capital controls) are not likely to be effective at reducing the impact of risk‐off episodes. However, prudential policies that limit leveraging or foreign exposure by Swiss banks may diminish the volatility of capital flows during risk‐off episodes. 相似文献
