Seven case studies—from Bolivia, Colombia, Indonesia,Mexico, Nicaragua, Taiwan (China), and Turkey—demonstratethe feasibility of conducting rigorous impact evaluations indeveloping countries using randomized control designs. Thisexperience, covering a wide variety of settings and social programs,offers lessons for task managers and policymakers interestedin evaluating social sector investments. The main conclusions are: first, policymakers interested inassessing the effectiveness of a project ought to consider arandomized control design because such evaluations not onlyare feasible but also yield the most robust results. Second,the acute resource constraints common in developing countriesthat often make program rationing unavoidable also present opportunitiesfor adopting randomized control designs. Policymakers and programmanagers need to be alert to the opportunities for buildingrandomized control designs into development programs right fromthe start of the project cycle because they, more than academicresearchers or evaluation experts, are in the best positionto ensure that opportunities for rigorous evaluations are exploited.   相似文献

Relational exchange arrangements supported by trust are commonly viewed as substitutes for complex contracts in interorganizational exchanges. Many argue that formal contracts actually undermine trust and thereby encourage the opportunistic behavior they are designed to discourage. In this paper, we develop and test an alternative perspective: that formal contracts and relational governance function as complements. Using data from a sample of information service exchanges, we find empirical support for this proposition of complementarity. Managers appear to couple their increasingly customized contracts with high levels of relational governance (and vice versa). Moreover, this interdependence underlies their ability to generate improvements in exchange performance. Our results concerning the determinants of these governance choices show their distinct origins, which further augments their complementarity in practice.

Modern charities are facing increasing pressures requiring them to use more effectively a range of marketing activities, and segmentation may be one such tool. The giving literature suggests that the demographic factors of gender and age might serve as appropriate segmentation criteria and this paper examines whether motivations of existing donors vary by age or gender. The results suggest that there may be limited benefits in segmenting existing donors and that charities may be able to use similar promotional strategies for all existing donors.

Nursing leaders in ambulatory care need to objectively quantify patient intensity to balance patient care needs and nursing resources. In this three-part series, current literature on acuity/intensity tools will be reviewed, and the development of an Ambulatory Intensity System (AIS) to objectively quantify nursing care will be described. In this article, the ongoing implementation of the system, its incorporation into the organization's established computerized appointment system, reliability measures, and related performance improvement activities will be discussed.  相似文献

This paper examines the bank lending relations of a large sample of technology and nontechnology firms that went public during the 1996–2000 period. We use a unique hand-collected data set to examine the characteristics of firms that establish pre- Initial Public Offering (IPO) bank lending relations and whether post-IPO performance is related to the existence and size of pre-IPO banking relations. We find that the majority of IPO firms have banking relations before they go public. Firms with banking relations are older, more profitable or, in the case of tech firms, have lower losses, and are more likely to have funding from venture capitalists than firms without banking relations. We also find that banks lent aggressively to technology firms in the sense that current earnings and cash flows were significantly less important in determining banking relations for technology firms than for nontechnology firms. Consistent with the importance of so-called soft information in lending decisions, we find that, controlling for ex ante observable risk measures, there is a positive and significant relation between improvements in post-IPO operating performance and the existence and size of pre-IPO banking relations. Overall, our results indicate that firms with the best current and future prospects establish banking relations. Our findings provide an explanation as to why investors could interpret lending relations as a positive signal of firm quality.  相似文献

Enterprises in post-socialist and transition economies often participate in providing infrastructure and social services to the surrounding community which in the Russian legal setting should be local authorities’ responsibility. We propose that this bundling of social and infrastructure goods provision with firm's core operations is a fully rational choice in an uncertain institutional environment. A unique survey data suggest that this manifests itself through more reliable infrastructure, stronger employee attachment to the firm and, most interestingly, through better relations with the authorities. Relationship with authorities is a two-way game where the firm gains from the arrangement but on the other faces sanctions if it decided to depart from it. Firm's participation in the arrangement is clearly enhanced by inherited fixed capital assets from the Soviet era.  相似文献

In 1998, a survey of the American Agricultural Economics Association was conducted by the Committee on Women in Agricultural Economics. The survey was the first in an ongoing tracking system, funded by the American Agricultural Economics Association Foundation, designed to track the progress of agricultural economics professionals over time, examine factors that influence their professional development, and investigate changes over time in the composition of the profession and issues influencing change. This study provides the background and objectives of the tracking system, the survey procedure, and basic demographics of the American Agricultural Economics Association and survey respondents.  相似文献

We model and calibrate the arguments in favor and against short-term and long-term debt. These arguments broadly include: maturity premium , sustainability, and service smoothing. We use a dynamic-equilibrium model with tax distortions and government outlays uncertainty, and model maturity as the fraction of debt that needs to be rolled over every period. In the model, the benefits of defaulting are tempered by higher future interest rates. We then calibrate our artificial economy and solve for the optimal debt maturity for Brazil as an example of a developing country and the US as an example of a mature economy. We obtain that the calibrated costs from defaulting on long-term debt more than offset costs associated with short-term debt. Therefore, short-term debt implies higher welfare levels.  相似文献
