Successful leaders create structural elements in order to achieve the performance objectives set forth by organizational strategy. Supply chain oriented structural elements are reflected in an organization's relationships, both within the firm and with supply chain partners. In this research effort, we examine how such structural elements can be created as a means through which to enhance performance. Our hypothesized model is rooted in strategy‐structure‐performance theory and integrates elements of servant leadership theory and social exchange theory to explain how building organizational commitment via servant leadership behaviors can ultimately impact performance. We use a survey method to collect data from 158 motor carriers. The results of our structural equation model support our hypotheses and serve to extend the discussion of supply chain structural elements and the role of leadership style in achieving organizational performance.  相似文献

This paper is the first attempt to analyze ITC Commissioner voting behavior on sunset reviews of antidumping cases. Sunset determinations entail greater complexity than initial antidumping investigations because ITC commissioners must account for the impact of dumping protection as well as competitive forces on industry conditions. Empirical findings indicate that ITC voting is based on both sunset regulation and nonstatutory factors. Results reveal apparent biases against Chinese competitors and poorer nations generally, and favorable treatment toward U.S. steel producers and high-wage industries. There is also evidence of preferential treatment of industries located in states of Senate oversight committee members. JEL no. F13  相似文献

Abstract . The concept of “self-efficacy” is used to test the hypothesis that the negative self-concept of welfare recipients coniributes to long term psychological and material dependency on such assistance. Self-efficacy focuses on the extent to which people are able to produce and regulate events in their lives and is associated with self-imposed performance expectations. The extent to which the minority status which Blacks occupy in this society decreases self efficacy relative to Whites is examined, using information generated from structured interviews with 290 low income Black and White women. Operationalizing the concept of self-efficacy with appropriate controls for socioeconomic status, family composition and other factors results in finding no racial differences in sense of self-efficacy between Black and White women. Observed differences in patterns of receipt of public assistance are found to be more directly related to the persistence of structural barriers to upward mobility that have differential impacts on Blacks and Whites. Long term receipt of public assistance is found to adversely affect both self-worth and work orientation/perceived efficacy for all women.  相似文献

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

Capital's commodity frontiers strategy has at once woven together regional differences within an expanding world‐system and remade the productive and reproductive activities of humans and the rest of nature. The development of successive commodity frontiers gave way to long waves of economic expansion that have been pivotal to accelerating accumulation and transcending capital's recurrent crises. In short, commodity frontiers are constitutive of world‐ecological moments premised on booms and crises of accumulation. In this paper, I examine the coal commodity frontier in Appalachia, to illustrate the region's history as one of succeeding frontiers in and out of the region over the long twentieth century of American capitalism. I argue that the origin of Appalachia's coal frontier was decisively made through the nineteenth‐century agricultural revolution expressed outside of the region. Appalachia's full‐fledged development was an outcome of capital's under‐reproduction strategies. The crisis of the region's frontier turned on a lack of surplus from under‐reproduction strategies, competing coal basins, economic diversification and competing energy sources. I find that the commodity frontier concept not only illuminates regional political economies and ecologies of difference, but also explains the production of nature of historical capitalism.  相似文献

Companies are increasingly using project finance to fund large-scale capital expenditures. In fact, private companies invested $96 billion in project finance deals in 1998, down from $119 billion in 1997 largely due to the Asian crisis, but up more than threefold since 1994. The decision to use project finance involves an explicit choice of organizational form as well as financial structure. With project finance, sponsoring firms create legally distinct entities to develop, manage, and finance the project. These entities borrow on a limited or non-recourse basis, which means that loan repayment depends on the project's cash flows rather than on the assets or general credit of the sponsoring organizations. Despite the non-recourse nature of project borrowing, projects are highly leveraged entities, with debt to total capitalization ratios averaging 60–70%. Petrozuata, a $2.4 billion oil field development project in Venezuela, is a recent example of the effective use of project finance for several reasons. First, the analysis shows a typical setting where project finance is likely to create value, that of a large-scale investment in Greenfield assets (in this case, wells, pipelines, and upgrader) that can function as a stand-alone economic entity and support a high leverage ratio. Given the nature of this investment, one can think of project finance as venture capital for fixed assets, except that the investments are 100 to 1000 times larger and financed primarily with debt rather than equity. Besides highlighting the types of assets appropriate for project finance, this article illustrates the sizeable transactions costs associated with structuring a deal as well as the full range of benefits accruing to project sponsors. The structure allows sponsors to capture tax benefits not otherwise available, reduces information costs for creditors and other investors, and lowers the overall cost of financial distress. The combination of high leverage, concentrated equity ownership, and direct control in project finance also addresses a wide range of incentive problems that destroy value in diversified companies. Analysis of the explicit contractual terms of the deal reveals a careful allocation of project risks in an attempt to elicit optimal behavior by each of the participants. As illustrated in the Petrozuata case, limiting completion and operating risks are important undertakings. But project finance is most valuable as an instrument for managing sovereign risks. Indeed, the ability of project finance to limit sovereign risk is the one feature that cannot be replicated under conventional corporate financing schemes.  相似文献

Many economists have long held that market failures create a gap between social and private returns to research and development (R&D), thereby limiting private incentives to invest in R&D. However, this common belief that firms significantly underinvest in R&D is increasingly being challenged, leading the rationale behind public support for private R&D to be questioned. In this paper, we attempt to clarify the perspectives of two sources: the theoretical literature on endogenous growth, and its recent developments in integrating a geographical dimension, and the empirical literature that measures the social returns to R&D in relation to the private returns. Ultimately, we are able to clearly distinguish among different types of market failures and compare their relative impact on the gap between the private and social returns to R&D. Two main conclusions are reached. First, systematic firm underinvestment in R&D is not demonstrated. Second, even though instances of underinvestment do occur, they are mainly explained by surplus appropriability problems rather than by knowledge externalities. This suggests the need for a new policy mix that employs more demand‐oriented instruments and is more concentrated on identifying efficient allocations among activities rather than merely increasing global private R&D investment.  相似文献

Recent food price increases reportedly caused significant numbers of households to fall into poverty, particularly in the developing world. Most research into the welfare effects of these food price changes assumes constant demand or approximates second order substitution effects. Poverty forecasts with these assumptions may overestimate or underestimate the effect of food price increases in a nation where most households consume diverse food baskets. We account for full substitution by calculating a theoretically consistent food demand system, accounting for household responses to food price changes by decreasing some food purchases and increasing other food purchases. We use Mexican data to confirm the mitigation of adverse welfare effects from food price increases after accounting for country-specific dietary preferences in modeling demand. In comparison to previous literature, our welfare measures predict theoretically consistent numbers of Mexican households entering poverty due to recent food price changes.  相似文献

In the continuing debate over the impact of genetically modified (GM) crops on farmers of developing countries, it is important to accurately measure magnitudes such as farm‐level yield gains from GM crop adoption. Yet most farm‐level studies in the literature do not control for farmer self‐selection, a potentially important source of bias in such estimates. We use farm‐level panel data from Indian cotton farmers to investigate the yield effect of GM insect‐resistant cotton. We explicitly take into account the fact that the choice of crop variety is an endogenous variable which might lead to bias from self‐selection. A production function is estimated using a fixed‐effects model to control for selection bias. Our results show that efficient farmers adopt Bacillus thuringiensis (Bt) cotton at a higher rate than their less efficient peers. This suggests that cross‐sectional estimates of the yield effect of Bt cotton, which do not control for self‐selection effects, are likely to be biased upwards. However, after controlling for selection bias, we still find that there is a significant positive yield effect from adoption of Bt cotton that more than offsets the additional cost of Bt seed.  相似文献
