This paper estimates Krugman’s (J Polit Econ 99:413–499, 1991) economic geography model using data from the Spanish NUTS 3 regions. The econometric formalization endogenously determines wages in a region as a function of income and wages in other regions. The specification adopted also allows us to study the relation between the agglomeration of economic activity, increasing returns and market access. The first result obtained is that the Spanish economy exhibits a spatial wage structure: wages in a region are positively determined by income and wages in neighboring regions. In second place it is found support for the structural relations of the underlying theoretical model, indicating the importance of scale economies and transport costs in shaping the Spanish economic geography. 相似文献

This article evaluates the ability of contingent valuation to measure the benefits received by several ethnic groups from a prescribed burning forest fire reduction program similar to President Bush's Healthy Forest Initiative. Reasons for refusing to pay higher taxes for the prescribed burning program were not statistically different between African Americans, Hispanics, and whites. Mean willingness to pay of whites was $400, whereas for African Americans it was $505, but the difference is not statistically significant. The results suggest a substantial statewide willingness to pay by whites and African Americans for forest fuel reduction projects using prescribed burning in California. (JEL Q26 , Q23 , J15 ) 相似文献

Firms are under constant pressure from various governmental and nongovernmental agencies to switch from conventional environmentally polluting products to green product innovations (GPIs). However, the relevant research pertaining to GPI has been published in a diverse set of journals that vary in their scope and readership and, therefore, the scholarly contribution to the topic remains largely fragmented. This study has utilised a systematic literature review approach to examine the literary corpus on GPI to paint a holistic picture of its different aspects. The content and thematic analysis of 85 studies resulted in the extraction of seven key research themes: organisational capabilities, organisational learning, institutional pressures, barriers, structural changes, benefits of GPI, and methodological choices. This study's findings further highlight the various gaps in the GPI literature and raise some research questions that warrant scholarly investigation in the future. Likewise, our study has important implications for practitioners who are likely to benefit from a holistic understanding of the different aspects of GPI. Similarly, policymakers can use this study's findings to introduce policy interventions, especially in countries where GPI adoption is low. 相似文献

A clear understanding of residents’ attitudes towards tourism development and its determinants is a crucial pillar for designing tourism development strategies to promote sustainable development. The literature on the influence of host–tourist interactions and place attachment on residents’ attitudes towards tourism development in developing countries is still scarce. To extend knowledge in this field, this study aims at developing and testing a structural model to examine direct and indirect causal effects of place attachment, host–tourist interaction, and perceived positive and negative tourism impacts on the residents’ attitudes towards tourism development in an island tourism destination – Boa Vista Island in Cape Verde. Results suggest that the residents’ attitudes are positively affected by place attachment, host–tourist interaction, and perceived positive impacts; and negatively affected by perceived negative impacts. Host–tourist interaction emerges as the strongest (direct and indirect) determinant of the residents’ attitudes towards tourism development. Moreover, although both positive and negative perceptions of tourism impacts have significant impacts on the residents’ attitudes, the influence of the former is stronger than that of the latter. The paper ends with relevant theoretical and practical implications to promote positive residents’ attitudes towards tourism development in Boa Vista. 相似文献

The effect of within-group heterogeneity on the survival of social groups is theoretically ambiguous. A greater diversity of ideas, experience, and networks can have a positive effect on members’ benefits from group membership, but diversity also creates a potential for conflict. This paper analyzes the relation between heterogeneity and exit of microcredit groups, using data from Angola. The results suggest that the form of group heterogeneity matters. Fragmentation in terms of social identities, or more specifically religious-linguistic fractionalization, is associated with a greater probability of group exit. Within-group economic inequality, however, is associated with a decrease in the probability of exit, but at a diminishing rate. 相似文献

Replanning is often used to optimize results of an activity in an ever changing world. To address the challenge of preparing future engineers for success, a special course was created for all engineering freshmen of the Faculty of Engineering of the University of Porto, in Portugal. Presented as a case study, this special course underwent a careful replanning as a result of several years of experience in teaching practice alongside with a theoretical deepening in pedagogical and technological issues, under the aegis of the action-research methodology. Within the context of the case study course, the mentioned replanning was also based on a theoretical approach that clearly identifies teaching–learning-assessment methodologies that promote regulation from those that foster emancipation, using a specific instrument: a taxonomy of educational processes. The replanning was designed to globally boost results regarding the educational aims of the course such as furthering freshmen’s integration into work environment and preparing them for success by fostering transversal skills (needed for study and work). Technology is seen as a mean of education enrichment as well as a productivity tool. The introduced innovations include fun-but-educational activities, several types of assessment over time and specific technological tools which were critical for the educational impact/achievement of this course. Success is demonstrated by encouraging feedback from the stakeholders, high students’ classifications and a steady reduction in retention. It is advocated that large portions of the reasoning behind the replanning can be extrapolated to other courses. 相似文献

This paper analyses the potential benefits from reforms aimed at promoting domestic demand in the region, as well as the effects of slower growth in the US and the G3 (US, euro area, and Japan) on the members of the Executives’ Meeting of East Asian-Pacific Central Bank (EMEAP). The analysis is based on simulation scenarios using an expanded version of the IMF Global Integrated Monetary and Fiscal (GIMF) model which is particularly useful for conducting medium-term policy analysis, as it incorporates rich layers of intra-regional trade, production, and demand allowing the transmission mechanism of structural reforms and external shocks to be fully articulated. The simulation results show that reforms to rebalance the pattern of demand in regional economies (such as Mainland China) more towards domestic demand could entail non-negligible benefits for the EMEAP. These benefits could be even larger for those economies that more flexibly adjust to the shift in China's trade pattern. The simulation results also demonstrate that structural reforms in EMEAP economies will allow them to reduce vulnerabilities to economic downturns in major economies. 相似文献

We develop a semi‐structural new‐Keynesian open‐economy model – with separate food and non‐food inflation dynamics to study the sources of inflation in Kenya in recent years. To do so, we filter international and Kenyan data (on output, inflation and its components, exchange rates and interest rates) through the model to recover a model‐based decomposition of most variables into trends (or potential values) and temporary movements (or gaps) – including for the international and domestic relative price of food. We use the filtration exercise to recover the sequence of domestic and foreign macroeconomic shocks that account for business cycle dynamics in Kenya over the last few years, with a special emphasis on the various factors (international food prices, monetary policy) driving inflation. We find that while imported food price shocks have been an important source of inflation, both in 2008 and more recently, accommodating monetary policy has also played a role, most notably through its effect on the nominal exchange rate. We also discuss the implications of this exercise for the use of model‐based monetary policy analysis in sub‐Saharan African countries. 相似文献

Environmental and socio-economic sustainability of chinampas (raised beds) in Xochimilco,Mexico City

The chinampas (raised beds) of Xochimilco, Mexico City, are highly productive, traditional wetland agricultural systems, which were able to feed most of the population in pre-hispanic times. There is a strong trend to substitute chinampas with plastic greenhouses for flower production, which creates negative impacts in the landscape, environment and culture. This study compares the environmental and socio-economic sustainability of chinampas and greenhouses, at both the farm and regional levels, using the MESMIS framework. Even though the results show that greenhouses are more profitable, the contribution of chinampas to ecosystem services cannot be substituted by greenhouses, as tree cover is lost, canals are filled and food is not provided. Greenhouses had a higher diversity, but also a higher agrochemical use and are heavily dependent on external inputs and subsidies. Chinampas have shifted from staple crops to commercial horticulture in order to remain a technically viable and economically feasible option for local farmers. However, compensation mechanisms for the provision of ecosystem services are urgently needed if this ancient system is to be maintained. The framework allowed the integration of indicators at both farm and regional scales, combining on-farm surveys with GIS techniques, which could assist in ecosystem service valuation. 相似文献
