Based on a village study in Tanzania, the effects of decentralized forest management on forest conservation, rural livelihoods and good governance are evaluated. Tree growth is estimated to exceed harvest, and forest utilization appears effectively controlled. Forest revenues cover the costs of management and finance local public services, but the underlying taxes and regulations have made the poorest worse off. Governance outcomes are also ambiguous. Revenues are administered transparently, but village leaders are coercive toward forest dependent minorities. The case provides a rare example of how decentralized forest management works in Africa when meaningful powers are devolved to local communities. 相似文献

Using data for 91 large banks from 45 countries, this paper finds that foreign, domestic private, and government-owned banks use different lending technologies and organizational structures for SME financing. The extent, type, and pricing of SME loans, however, is not strongly correlated with lending technologies and organizational structures, suggesting that SME financing need not be based only on ??relationship lending??. Consistent with these results, we find few significant differences in the extent, type, and pricing of SME loans across bank types. Instead, we find significant differences across developed and developing countries, driven by differences in the institutional and legal environment. 相似文献

Recently, developing countries have witnessed a sharp increase in foreign bank participation. We examine the impact on banking outreach using newly gathered data for Mexico, where foreign bank participation rose from 2% to 83% of assets during 1997–2005. Country-, bank-, and bank-municipality-level estimations show a decline in the number of deposit and loan accounts. While country- and bank-level estimations indicate an increase in the share of municipalities with bank branches and in the likelihood of bank presence, bank-municipality regressions show that only rich and urban municipalities benefited. Overall, the evidence is consistent with a decline in outreach. 相似文献

Since the subprime crisis, portfolios based on risk diversification are of great interest to both academic researchers and market practitioners. They have also been employed by several asset management firms and their performance appears promising. Since they do not rely on estimates of expected returns, they are assumed to be robust. The same argument holds for minimum variance and equally weighted portfolios. In this paper, we consider a Monte Carlo simulation, as well as an empirical global portfolio dataset, to study the effect of estimation errors on the outcomes of two recently proposed asset allocations, the equally weighted risk contribution (ERC) and the principal component analysis (PCA) portfolio. The ERC portfolio is more robust to changes in the input parameters and has a smaller estimation error than the Markowitz approaches, whereas the PCA portfolio is even more unstable than the classical approaches. In the worst-case scenario, neither approach delivers what it promises. However, in every case the resulting return?Crisk relationship is dominated by the Markowitz approaches. 相似文献

Legal Theories of Financial Development 总被引:2,自引:0,他引:2
This paper examines legal theories of international differencesin financial development. The law and finance theory stressesthat legal traditions differ in terms of (i) their emphasison the rights of private property owners vis-à-vis thestate and (ii) their ability to adapt to changing commercialand financial conditions, so that historically determined legaltraditions shape financial development today. Other theoriesreject the centrality of legal tradition in accounting for cross-countrydifferences in financial development. The results are broadlyconsistent with legal theories of financial development, thoughit is difficult to identify the precise channel through whichlegal tradition influences financial development. 相似文献
