This study examines the effect of land fragmentation on school dropout of children in Vietnam. To address the endogeneity issue, the study proposes an instrumental variable – that is land per capita at the commune level. The study also uses another instrumental variable – the percentage of land plot acquisition before 1993 – to check the robustness of the results. The findings are that higher land fragmentation decreases child school dropout. Land fragmentation has significant impacts on school dropout of children aged 10–15, however, it does not have any impact on school dropout of children aged 6–10. We explain these findings through one particular mechanism – that is women empowerment. A higher level of land fragmentation increases women empowerment in deciding to visit family, friends or relatives, the purchase of daily goods, large purchases, their own health, and their children’s health. A variety of robustness checks corroborate these findings.  相似文献

The year 2019 in Brazil was marked by environmental setbacks, which catalyzed the increase of illegal deforestation and fire rates in the Brazilian Amazon. In the Amazon region of Maranhão state, original forest cover diminished from 25 % (24,700 km2) in 2016 to 24 % (23,967 km2) in 2019, and 6,038 km2 of remaining forests were degraded by fires and/or illegal logging – processes related to high levels of violence against indigenous and rural communities. Almost half of all deforested areas in the region (36,060 km2) are considered a global restoration hotspot, however secondary vegetation remains unprotected and 8,294 km2 were cleared between 2014 and 2018. Due to uncontrolled deforestation and fragmentation, Maranhão has no more forest core areas (outside protected areas) with the minimum size to ensure sustainable forest management practices for timber production. New policies at the state level must promote old-growth and secondary forest conservation and restoration. However, the trends point to the opposite direction: the Ecological-Economic Zoning (ZEE) allows the reduction of forest protection and the State Forest Policy reinforces federal legislation setbacks. The Amazon region of Maranhão state has forest aptitude, and forest and agroforestry product chains would bring social and environmental benefits, making them the best opportunity for sustainable economic development in the region. Therefore, the forest must be re-planted for the benefit of people and nature.  相似文献

Specialization in high-tech products is frequently used to capture technological intensity of exports. A number of developing countries are among the most deeply specialized countries in exports of these products. The paper shows that the bulk of high-tech exports can actually be attributed to the effect of international fragmentation of production in electronics on trade statistics. It is confirmed in an econometric framework that while indigenous technological capabilities are associated with export performance in electronics, it is the propensity to import electronics components that accounts for by far the largest proportion of cross-country differences in specialization in electronics exports.

Our purpose is to estimate a model of non-industrial forest landowner behavior that considers certain types of behavior that have escaped discussion and rigorous investigation in the literature, yet which are critical to future policy making. Our focus on the many different but related decisions landowners make broadens the typical understanding of landowner behavior to show how bequest motives, debt and participation in non-timber activities, and harvesting decisions are interrelated and dependent on landowner preferences, market, and land characteristics.  相似文献

Urban plans and projects that aim to initiate the redevelopment and gentrification of urban areas create social and ecological pressures on urban environments and thereby stimulate urban movements. These movements have a lifespan, which evolves in interaction with planning authorities under local or central governments and may be marked by institutionalization and co‐optation, as well as fragmentation among the people involved in them. Fragmentations are usually based on conflicting individual and collective interests, but may also be the result of different political perspectives in groups. This article is based on a case study conducted in two adjacent gecekondu neighbourhoods of Istanbul, Gülsuyu and Gülensu, where urban politics have played an important role in efforts to resist plans for urban transformation. It shows that fragmentations are very likely to occur in urban movements during planning processes in a neoliberal era, owing to the different perspectives in the movement on what the just city is.  相似文献

Archipelago began reporting trades and quotes to the Pacific Stock Exchange in 2002 for NYSE-listed securities and in 2003 for NASDAQ-listed securities. These events mark the time that Archipelago began migrating stocks from its ECN platform to the exchange platform, thereby becoming a stand-alone exchange. We examine the impact of becoming a stand-alone exchange on execution quality and market share of Archipelago to gain insight into its ability to compete for order flow in NYSE and NASDAQ stocks. We find that the change has a positive effect on Archipelago's execution quality for NYSE stocks, while it has a negative effect for NASDAQ stocks. A possible explanation is that Archipelago lost the large pool of liquidity that SuperMontage provided when it became a stand-alone exchange, and that loss may offset any gain associated with having exchange status. Overall, exchange status helped Archipelago slowly make headway in the NYSE-listed securities arena.  相似文献

We assess the degree of market fragmentation in the euro-area corporate bond market by disentangling the determinants of the risk premium paid on bonds at origination. By looking at over 2400 bonds we are able to isolate the country-specific effects which are a suitable indicator of the market fragmentation. We find that, after peaking during the sovereign debt crisis, fragmentation shrank in 2013 and receded to pre-crisis levels only in 2014. However, the low level of estimated market fragmentation is coupled with a still high heterogeneity in actual bond yields, challenging the consistency of the new equilibrium.  相似文献

In this symposium, we explore how urban citizenship is about expressing, if not producing, difference, and how fragmentation of claims affects urban citizenship and right to the city movements with their universal, all‐inclusive ideals. Investigating social movements, political participation and conflicting diversities in public space in Tel Aviv and Berlin, we see a trend towards a diversification of interests, a weakening of movements, and even a competition over rights and resources rather than a development of mutual support and solidarities among various groups on the pathway to a livable city. This tension, we argue, deserves attention. Radical urban scholarship and politics need to better understand the historical and place‐specific contexts that structure the formation of citizenship claims and the courses that citizenship struggles take. Celebrations of urban citizenship as a more contextualized, community oriented, and bottom‐up framework (in comparison to national citizenship) should therefore be complemented by a careful investigation of their fragmented and fragmenting practices.  相似文献
