We extend the Salter-Swan model to include both factor markets and semi-traded goods. In our model, changes in relative factor prices depend on changes in world commodity prices, factor endowments, and the trade balance. In contrast, only changes in world commodity prices can affect factor prices in the neoclassical trade model. The inclusion of semi-traded goods weakens the magnification effect in both the Stolper-Samuelson and Rybczynski theorems. When imports and domestic goods are poor substitutes, a characteristic of some commodities in developing countries, the sign of the Stolper-Samuelson theorem is reversed.  相似文献

This paper presents the first empirical analysis of firms’ rationale for issuing putable convertible bonds in the literature. We distinguish between three possible rationales for the issuance of putable convertibles: 1) the risk-shifting hypothesis, 2) the asymmetric information hypothesis, and 3) the tax savings hypothesis. The results of our empirical analysis can be summarized as follows. First, putable convertible issuers are larger, less risky firms, having larger cash flows, smaller growth opportunities, and lower bankruptcy probabilities as compared to ordinary convertible issuers. Second, putable convertible issuers have lower preissue market valuations, more favorable announcement effects, and better postissue operating performance when compared to ordinary convertible issuers. Third, putable convertible issuers have better postissue long-run stock return performance as compared to ordinary convertible issuers. Finally, putable convertible issuers typically have greater tax obligations and better credit ratings than ordinary convertible issuers. Overall, the results of our univariate as well as multivariate analyses provide support for the asymmetric information and tax savings hypotheses, but little support for the risk-shifting hypothesis.  相似文献

The growing reliance on volunteers in Australia has heightened the need for non‐profit organisations to retain these valuable resources. However, the current literature on volunteer retention is limited. One potential way volunteers can be retained is by providing learning and development opportunities (LDOs). This study investigates the relationship between volunteer perceptions of LDOs, their motivations for volunteering, and retention. Analyses revealed significant main effects for LDOs and volunteer motivations on retention and several interactive effects demonstrating that LDOs can have differential effects on retention depending on the reasons for volunteering.  相似文献

Disaster relief presents many unique logistics challenges, with problems including damaged transportation infrastructure, limited communication, and coordination of multiple agents. Central to disaster relief logistics is the distribution of life-saving commodities to beneficiaries. Operations research models have potential to help relief agencies save lives and money, maintain standards of humanitarianism and fairness and maximize the use of limited resources amid post-disaster chaos. Through interviews with aid organizations, reviews of their publications, and a literature review of operations research models in transportation of relief goods, this paper provides an analysis of the use of such models from the perspective of both practitioners and academics. With the complexity of disaster relief distribution and the relatively small number of journal articles written on it, this is an area with potential for helping relief organizations and for tremendous growth in operations research.  相似文献

It is acknowledged that social capital plays an important role in the growth of entrepreneurial firms. However, few studies have examined the contribution and function of social capital networks that contain structural holes (heterogeneous networks) in emerging economies. It is not clear how trustworthiness and behavioural commitment impact on effectiveness of these networks in obtaining resources. This study explores how heterogeneous networks characterize successful entrepreneurship of small-medium enterprises in such setting. We find that behavioural commitment moderates the relationship between heterogeneous networks and resource acquisition, while trustworthiness does not significantly moderate this relationship. The impact of the findings on the literature and practice in emerging economies is discussed, as is the need for future research in this domain.  相似文献

Perhaps the most common criticism of socially responsible investment funds is that imposing non‐financial screens restricts investment opportunities, reduces diversification efficiencies and thereby adversely impacts performance. In this study we investigate this proposition and test whether the number of screens employed has a linear or curvilinear relation with return. Moreover, we analyse the link between screening intensity and risk. Screening intensity has no effect on unadjusted (raw) returns or idiosyncratic risk. However, we find a significant reduction in α of 70 basis points per screen using the Carhart performance model. Increased screening results in lower systematic risk – in line with managers choosing lower β stocks to minimize overall risk.  相似文献

The use of joint modelling approaches is becoming increasingly popular when an association exists between survival and longitudinal processes. Widely recognized for their gain in efficiency, joint models also offer a reduction in bias compared with naïve methods. With the increasing popularity comes a constantly expanding literature on joint modelling approaches. The aim of this paper is to give an overview of recent literature relating to joint models, in particular those that focus on the time‐to‐event survival process. A discussion is provided on the range of survival submodels that have been implemented in a joint modelling framework. A particular focus is given to the recent advancements in software used to build these models. Illustrated through the use of two different real‐life data examples that focus on the survival of end‐stage renal disease patients, the use of the JM and joineR packages within R are demonstrated. The possible future direction for this field of research is also discussed.  相似文献
