We take advantage of repeated cross‐sectional household surveys and a sharp discontinuity created by the introduction of an unconditional cash transfer to elders in Bolivia, to evaluate its impact on educational expenditures on children within a household. We find positive and significant impacts of the program at the aggregate level. We also find that the program has stronger effects on indigenous populations as well as on female and rural populations. Our results are robust to a series of falsification tests, survey structure, model specification, and estimation methods.  相似文献

Data are a key component in the design, implementation, and evaluation of economic and social policies. Monitoring data quality is an essential part of any serious, large‐scale data collection process. The purpose of this article is to show how paradata should be used before, during, and after data collection to monitor and improve data quality. To do this we use timestamps, global positioning system (GPS) coordinates, and other paradata collected from an 800‐household survey conducted in Tanzania in 2016. We demonstrate how key paradata can be used during each phase of a research project to identify and prevent issues in the data and the methods used to collect it. Our results corroborate the importance of collecting and analyzing paradata to monitor fieldwork and ensuring data quality for micro data collection in developing countries. Based on these findings we also make recommendations as to how researchers can make better use of paradata in the future to manage and improve data quality. We argue for an expansion in the understanding and use of varied paradata among researchers, and a greater focus on its use for improving data quality.  相似文献

This study extends current knowledge of upper echelon executive compensation beyond the CEO, specifically CFO compensation, based on whether they possess generalist or specialist skills. We find that “strategic” CFOs with an elite MBA (generalist) consistently command a compensation premium, while “accounting” CFOs (specialist) and CFOs with a non‐MBA master's degree, even from an elite institution, do not. Further, scarce “strategic” CFOs are awarded both higher salaries and higher equity‐based compensation. Our findings support the view that unique complementarities between scarce CFOs and firms increase these executives' bargaining power leading to pay premium. Our results are robust to post‐hiring years, firm sizes, board characteristics, and CFO's insider/outsider status. We contribute at the confluence of upper‐echelon compensation, executive human capital, resource‐based view, and assortative matching literatures. Copyright © 2014 John Wiley & Sons, Ltd.  相似文献

The twenty‐first century labour market requires employees that proactively shape innovations and solve complex problems. Professionals in the education sector are expected to perform innovative behaviour that not only entails the generation, but also the realization and sustainable implementation of new ideas. In a sample of 458 employees in Dutch secondary and higher vocational education (abbreviated in Dutch to MBO and HBO, respectively), this study investigated the relation between environmental factors (namely task variety, management support and exposure to innovation) and Innovative Work Behaviour (IWB) across the different phases of the innovation process, including a sustainability phase. Results of hierarchical regression analyses showed that management support and exposure to innovations served as a predictor for all phases of IWB. Teachers with supportive managers and a high degree of exposure to innovations showed higher scores on innovative behaviour across all phases. Linear regressions revealed a significant relationship between task variety and IWB. In the hierarchical model, only management suport and exposure to innovations showed significant relations. Background characteristics, such as gender, age, tenure, number of working hours and type of education, for which we controlled during the analyses, played a role in how much IWB is displayed. It can be concluded that a work environment, in which employees are exposed to innovation and are supported is crucial. Additionally, in view of the role background characteristics play, it is recommended to select teachers with specific profiles for the different phases of the innovation process.  相似文献

We investigate the association between voluntary formation of board investment committee (IC) and corporate cash holdings of nonfinancial firms over the corporate life cycle stages for a large sample of Gulf Cooperation Council firms during 2005–2016. We find that IC increases corporate cash holdings in growth and maturity stages of firm, compared to introduction, shake‐out, and decline stages. These results have important implications for investors, policy makers, and regulators. Our findings are robust to various econometrics specifications.  相似文献

Although the organic sector is still relatively small, the demand for organic food is increasing throughout the world. The characterization of consumers' perception of and attitudes towards organic food is important to enable the development of marketing policies aimed at attracting conventional consumers to the sector. Consumers' behaviour studies must be conducted specifically for different regions and countries as perceptions and attitudes vary across the world. In the present study, a questionnaire was designed for administration to consumers in Galicia (Northern Spain). The questionnaire was administered to 830 consumers in 200 establishments to obtain data about the consumers' perception of and attitudes towards organic food. The survey results showed that one‐third of responders consume organic food and that the typical profile of a consumer of organic food is a middle‐aged, medium‐high class, university‐educated female living in a large village, who shops in supermarkets and preferably consume vegetables, fruits and eggs. Most people who declared that they consume organic products confuse these with home and locally produced food, indicating the potential for growth of the organic sector by providing such consumers with appropriate information. Most consumers (including conventional consumers) have a good opinion of organic food and consider that it is better for health, is of better quality than conventional food and avoid pesticide residues. However, price continues to be a barrier to the consumption of organic produce. Most respondents stated that they would consume more organic food if the price was only between 10% and 30% higher than the conventional equivalent. Finally, organic consumers in Galicia showed positive attitudes towards using local breeds in organic agriculture, both for producing food and for ecotourism and educational activities. Such activities could contribute to conserving breed biodiversity and adding value to organic farming.  相似文献

The promotion system for French academic economists provides an interesting environment to examine the promotion gap between men and women. Promotions occur through national competitions for which we have information both on candidates and on those eligible to be candidates. Thus, we can examine the two stages of the process: application and success. Women are less likely to seek promotion, and this accounts for up to 76 percent of the promotion gap. Being a woman also reduces the probability of promotion conditional on applying, although the gender difference is not statistically significant. Our results highlight the importance of the decision to apply.  相似文献

In the first phase of pharmaceutical development, and assuming that the probability of positive response increases with dose, the main statistical goal is to estimate a percentile of the dose–response function for a given target value Γ. We compare the Maximum Likelihood and centred isotonic regression estimators of the target dose and we discuss several performance criteria to assess inferential precision, the amount of toxicity exposure and the trade-off between them for a set of some exemplary adaptive designs. We compare these designs using graphical tools. Several scenarios are considered using simulation, including the use of several start-up rules, the change of slope of the dose-toxicity function at the target dose and also different theoretical models, as logistic, normal or skew-normal distribution functions.  相似文献

This paper explores the relationships between proactive environmental strategy (PES) and internationalization in emerging markets multinationals from Latin America (Multilatinas). Drawing on the resource‐based view and institutional theory and using a sample of 86 listed firms during the period 2013–2017, we find that Multilatinas with higher tiers of PES are associated with higher degrees of geographic international diversification. Because adopting PES is directly conditioned by institutional pressures to comply with stakeholders' regulations and expectations, Multilatinas that implement advanced PES will be able to achieve a higher level of international presence in foreign markets. Our results also reveal that board independence positively moderates the relationship between PES and geographic international diversification. Specifically, board independence provides Multilatinas with the opportunity to integrate valuable knowledge and expertise and thus to take advantage of implementing advanced PES to achieve even greater levels of internationalization. This study expands understanding of how environmental strategies influence internationalization of firms in the Latin American business context.  相似文献
