This paper aims to test the effects of social interaction and input spillovers on the agricultural performance of family farms in mixed paddy rice production (organic and conventional farming). Using survey panel data from a Chinese village, we adopt a Spatial Durbin Model (SDM) derived from spatial econometrics to disentangle the social interaction effect from spillover effects and to control for technological heterogeneities. Our analysis reveals a negative social interaction effect indicating that an increase in the yield of neighbouring plots leads to a decrease in the yield of the plot itself. We also find input spillovers. Labour, capital costs, water and organic pesticides have positive spillovers while external nutrients (nitrogen and phosphate) have negative spillover effects. Our study thus calls for a better understanding of social interactions and spillover effects among farmers in the promotion of sustainable family farming.  相似文献

Abstract

We observe and analyse three intra-industry foreign direct investment (FDI) spillover transmission channels using unique firm-level data collected from on-site interviews and observations regarding domestic and foreign firms operating in Uganda in 2015. Our main results are: (1) the spillover effects mainly depend on the channel(s) by which they occur (the competition channel is most important while spillover benefits through the worker mobility and the imitation channels are less prevalent) and (2) both positive and negative spillover effects occur within the same channel and, moreover, effects differ by channel for the same case. These are novel and challenging findings that have not yet been recognised in theoretical and empirical research on FDI spillovers. Our results suggest that long-term pecuniary spillover effects are predominantly stimulated via the competition channel and show that only limited short-term and long-term technological spillover effects occur through the imitation and the movement of workers channels. These channels are not only less prevalent, but also appear to be constrained by competition-determined spillovers. We are confident that these directions for future research will have a high pay-off because, as shown by this exploratory fieldwork, a more complete picture of the spillover effects is reached when the channels are considered simultaneously.  相似文献

The usual perspective on technology spillovers from FDI sees the MNC subsidiary as a passive actor. It presumes that the technological superiority that spreads from subsidiaries to other firms in the host economy is initially created outside it by MNC parent companies, and is delivered to subsidiaries via international technology transfer. The role of subsidiaries is little more than to act as a ‘leaky container’ lying between the technology transfer pipeline and the absorption of spillovers by domestic firms. This paper suggests a different model in which a substantial part of the potential for spillover is created within local subsidiaries as a result of their own knowledge-creating and accumulating activities in the host economy. We explore empirically the effects of these activities on technology spillovers from FDI using data for industrial firms in Argentina over the period 1992–96. The analysis suggests that significant results can be obtained incorporating subsidiaries' own technological activities as an explanatory variable of the spillover process.  相似文献

This article examines intra‐industry spillovers from FDI in Uruguayan manufacturing plants in 1988, to determine whether differences in the technology gap between locally‐owned plants and foreign affiliates have any impact on the relation between local productivity and foreign presence. We find a positive and statistically significant spillover effect only in a sub‐sample of locally‐owned plants with moderate technology gaps vis‐à‐vis foreign firms. Our interpretation is that there are firm‐specific differences in the ability to absorb spillovers, and that these may explain some of the contradictory findings of earlier spillover studies.  相似文献

This paper investigates the role of inter-firm interaction and geographical proximity in the determination of productivity spillover effects from foreign to domestic firms. We developed an estimation approach using the Spatial Durbin model and applied this to a firm-level dataset from Vietnam from 2000–2005. We found that productivity spillovers diminished when the distance between foreign and domestic firms increases and that interactions among local firms amplify the spillovers. Within short distances, the presence of foreign firms creates positive backward, negative forward and horizontal spillovers. Based on the findings, several implications are extracted regarding promotion policy for foreign direct investment in developing countries.  相似文献

We analyse the impact of a junior farmer field school project in Northern Uganda on students’ agricultural knowledge and practices. We also test for the presence of intergenerational learning spillover within households. We use differences-in-differences estimators with ex-ante matching and find evidence that the programme had positive effects on students’ agricultural knowledge and adoption of good practices. The project also produced spillover effects in terms of improvements of household agricultural knowledge and food security. Overall, our results point to the importance of adapting the basic principles of farmer field schools to children.  相似文献

Using firm-level panel data from the Taiwanese Census of Manufactures for 1986 and 1991 in the context of a modified selection model, we focus on three activities that contribute to the productivity growth of firms in the electronics industry: research and development, direct foreign investment and exports. In particular we address the issue of whether, in addition to the direct benefits of these activities, there are spillovers to other firms within the same four-digit industry or within the same geographical county. Our empirical results indicate that while the survival and direct productivity growth effects of R&D, exports and DFI are positive and statistically significant, intra-industry and geographical spillover effects are consistently present only for the export activity. That is, a firm's expected future TFP is positively and significantly affected by being located in a county and industry with more export activity. In addition, there is some evidence that the indirect effects generated by DFI firms, in the form of location spillover benefits to other firms, are also positive and significant. Finally, the empirical results indicate that the above direct and indirect benefits of the technological activities under study accrue principally to Taiwan's small and medium enterprises, rather than its large firms.  相似文献

In this article we conduct a large quantitative survey of the literature on horizontal and vertical spillovers from foreign direct investment (FDI). We create a unique database of spillover estimates for each country examined in the literature. Next, we estimate the average effect corrected for publication selection bias (the preferential selection of positive and significant estimates for publication). Our results suggest that an average reported estimate of backward spillovers is statistically significant. Publication selection is evident only among studies published in peer-reviewed journals, and only among the estimates that authors consider most important. Authors with small data sets engage in more publication selection. The intensity of selection in the literature decreases over time, which supports the economics-research-cycle hypothesis.  相似文献

Today, three independently originated interests are led by their implications to converge upon needed reform of public education. One of these interests arises from the shift by employers from the “command and control” model of management to a model of managers as facilitators. Another arises from the demand for “more integrity” in business, public administration, and the professions, in response to repeated exposures of corruption over the past decade. The third is the autonomous interest of education in preserving and supporting, rather than extinguishing, the innate motivation to learn that is evident in infants and young children.

At a time when proposals for educational reform are coming from many quarters but differ widely on principles and aims, my argument is that the three national interests that are identified above can be shown to converge upon the direction educational reform should take. That direction is away from education as “jug to mug” knowledge transference (the educational equivalent of “command and control” management), and into participatory education in which the spontaneous interests of students have an important role in shaping the curriculum, and the initiatives of students are utilized in the conduct of their classrooms and their schools. Only in this way can schooling serve to develop the autonomous initiatives of individuals that are required alike by facilitative management, by the educational goal of lifelong learning, and for the acquisition by persons of the cardinal moral virtues whose backbone we term integrity.  相似文献

We implemented a 16-month randomised field experiment in unelectrified areas of Bangladesh to identify health impacts of solar lanterns among school-aged children. Our analysis of various health-related indicators – self-reporting, spirometers, and professional medical checkups – showed modest improvements in eye redness and irritation but no noticeable improvement in respiratory symptoms among treated students. Varying the number of solar products received within treatment households did not alter these results. This limited health benefit was not caused by nonutilisation of the products by treated children, spillover effects from treated to control students, or contamination resulting from unfavourable family cooking environments.  相似文献

Inflows of foreign direct investment generate externalities that spill over to domestic firms and raise their productivity. This article examines the extent of spillover effects of foreign direct investment for firms in the highly disaggregated garment (ISIC 3221) and electronics industries (ISIC 3832) in Indonesia. Both are export-intensive industries, but differ greatly in technological sophistication and labour intensity. Changes in both the productivity level and rate of growth in each industry are decomposed into the effects of technological change, technical efficiency change and scale efficiency change and then the impacts of spillovers on each component and on total productivity are estimated. The findings suggest that foreign direct investment generates a positive effect on total productivity change, technical efficiency change, technological change, and scale efficiency change in the garment industry. In contrast, foreign direct investment contributes significantly negatively to total productivity, technological change and scale efficiency change, but has no significant effect on technical efficiency change in the electronics industry.  相似文献

This paper uses Mexican household data on water treatment to provide empirical evidence on the relationship between risk preferences and use of preventive health measures. The main finding is that in households with children, more risk-averse mothers are more likely to treat the water the household consumes. This result suggests that while households may face external constraints on their behaviour, personal preferences are also determinants of their choices.  相似文献

ABSTRACT

This article explores how a dynamic performance management (DPM) approach can give policy makers a more integrated, time-related understanding of how to address wicked problems successfully. The article highlights how an outcome-based approach to solving wicked policy problems has to balance three very contrasting objectives of stakeholders in the policy making process – improving service quality, improving quality of life outcomes and improving conformity to the principles of public governance. Simultaneous achievement of these three objectives may not be feasible, as they may form an interactive dynamic system. However the balancing act between them may be achieved by the use of DPM. Policy insights from this novel approach are illustrated through a case study of a highly successful co-production intervention to help young people with multiple disadvantages in Surrey, UK. The implications of DPM are that policy development needs to accept the important roles of emergent strategy and learning mechanisms, rather than attempting ‘blueprint’ strategic planning and control mechanisms. Some expectations about the results may indeed be justifiable in particular policy systems, as clustering of quality of life outcomes and outcomes in the achievement of governance principles is likely, because behaviours are strongly inter-related. However, this clustering can never be taken for granted but must be tested in each specific policy context. Undertaking simulations with the model and recalibrating it through time, as experience builds up, may allow learning in relation to overcoming barriers to achieving outcomes in the system.  相似文献

Policy makers have become increasingly interested in addressing the cultural dimensions of child support, "responsible fatherhood," and marriage in poor communities. However, policy studies have primarily focused on identifying economic determinants of these issues, with a substantial amount of variation in their statistical models left unexplained. This article draws on in-depth interviews the author conducted with disadvantaged mothers and fathers to illustrate how a systematic investigation into the meaning of low-income men's ties to families may fill in or provide alternative explanations for some important questions related to paternal involvement. In particular, it suggests that analyzing fathers' relationships through a cultural lens may not only reveal new information about the meaning of their emotional involvement, informal support, care of children, and conflicts with mothers which future policy studies should consider but may also inform policy initiatives by reducing the risk that they will be misdirected or have unintended consequences for poor families.  相似文献

In recent years, the phenomenon whereby key individuals introduce effective ideas into policy processes has been identified as a vital agent in the redefinition of policy issues. In turn, this raises the basic question of how these individuals themselves undergo processes of learning and change. The article examines three models of policy learning in order to analyse what they may tell us about the dynamics of individual learning: the advocacy coalition framework; the process of learning by means of ‘development’; and issue redefinition through processes of punctuated equilibria. The models are examined in the context of the learning dynamics of three key individuals within the salient anti‐bypass group the ‘Third Battle of Newbury’. The article’s conclusion identifies three apparent paradoxes in individual learning dynamics and attempts to answer these with particular reference to the concepts of frame reflection and regulation by means of norm setting.  相似文献

This paper uses plant-level data from Chile to examine the determinants of importing intermediate inputs paying special attention to the role of importing spillovers. The results show that plants that pay higher wages and plants with previous experience importing intermediate inputs are more likely to import inputs. This study also finds a positive correlation between the number of importers in the same region, regardless of their industry affiliation, and the probability of importing intermediate inputs. This suggests that importing spillovers may be important, at least in the case of Chilean manufacturing.  相似文献

This article offers an analytical framework for understanding the missing links between FDI and development, and applies it to the high technology sectors of Costa Rica and Mexico, the two countries in Latin America that have attracted the highest percentage of FDI in manufacturing. Since the advancement of knowledge-based assets in this sector is at the heart of structural change and development, we focus specifically on the conditions that enable or prevent positive knowledge spillovers from FDI. We identify two main reasons for the missing links between high-tech FDI and the development of indigenous knowledge-based assets in Costa Rica and Mexico. First, their governments did not have a coherent strategy, which would have spelled out the needed government policies to advance national capabilities, overcome market failures, and support the integration of national producers into TNCs’ global production networks. Second, there were limitations on the spillover potential from FDI. In Costa Rica and Mexico, technology or scale requirements for inputs made it difficult for large TNCs to source domestically beyond simple inputs like packaging materials. In Mexico, fundamental changes in the organization of global production chains in the computer industry led TNCs to rely on their global contract manufacturers rather than work with potential Mexican input suppliers.  相似文献

A “generic” oriented management course was developed for business and public administration majors. A study was completed to determine the effects of learning generic management principles with 48 college students. Results indicate that generic learning can be fostered without adversely affecting the learning of management principles specific to either business or public administration. Similar generic learning did not take place in a control group consisting of 39 students. A discussion of generic management and implications for further study are offered.  相似文献

This article estimates the returns to education for households who derive part of their income from household based non-farm self-employment ventures in rural Peru. While education is an individual level variable, earnings are observed at the household level. This asymmetry complicates both the estimation and the interpretation of the returns to education. This article is the first jointly to incorporate three channels through which education affects household earnings. Education affects earnings through the marginal productivity of labour (worker effect), labour allocation across activities (between-activity allocative effect) and its production externality effect (spillover effect). The results suggest that the between-activity allocative effects of education dominate the returns. This article also makes novel use of economic geography to proxy for the role that access to markets plays in determining these returns. In particular, altitude is a strong predictor of activity choice and the returns to education in this mountainous country.  相似文献

ABSTRACT

Can we pave the way to world peace through education of the next generation? This paper focuses on how teaching social and emotional learning (SEL) skills in schools could promote the positive development of children and youth so that they can choose prosocial, nonviolent ways of building relationships with others. First, research on how belonging and fairness develop early in life is briefly reviewed. Then the authors introduce SEL and the research supporting its impact, and explain how it can be supported through various strategies in the classroom, including programs, teacher–student relationships, cooperative learning, approaches to discipline, and solving problems and dealing with conflict peacefully. Building peace by promoting social and emotional development through education offers hope for future generations.  相似文献
