I examine the impact of usury laws on the Peruvian credit market between 1825 and 1852. Using a new data set of nearly 2,000 loans from archival sources, I show that the repeal of colonial anti-usury laws in early 1833 had an important effect on the allocation of credit in Lima. It increased interest rates and promoted access to credit. Furthermore, lenders made loans with greater maturities after the repeal of usury laws. 相似文献

Access 是微软公司推出的基于Windows的桌面关系数据库管理系统,是Office系列应用软件之一.它提供了表、查询、窗体、报表、页、宏、模块7种用来建立数据库系统的对象;提供了多种向导、生成器、模板,把数据存储、数据查询、界面设计、报表生成等操作规范化;为建立功能完善的数据库管理系统提供了方便,也使得普通用户不必编写代码,就可以完成大部分数据管理的任务.如果我们能够实现Access与Office组件其他成员之间进行数据交流,就能达到取长补短、提高工作效率的目的.本文就针对Access在word、Excel中的交叉应用进行了探讨. 相似文献

This paper studies the targeting outcomes of a self-targeted rice subsidy program in the Philippines. We find modest within-community targeting outcomes, but weak between-community targeting. This appears to be because, controlling for the direct influence of household characteristics, participation was lower in poorer communities. These inter-community differentials are strongly correlated with several proxies for citizen “voice”, including education, income, and access to other public services. This suggests that self-targeting outcomes are not simply a function of the good selected for subsidy, but are also influenced by variations in communities’ access to usable services; that these variations favor richer communities; and that efforts to enhance consumer voice in disenfranchised communities would facilitate targeting improvements. 相似文献

During the last decades, the widespread growth of information and communication technologies (ICT) has posed incentives to broaden the participation of individuals in social, political and economic dimensions of life. However, utilization of ICT also involves access to technology and infrastructure, and acquisition of skills to deal with innovations and, thus, digital literacy is, primarily, a complementary good. The digital divide expresses inequalities in access and utilization of ICT among individuals and populations in different countries. The study adopts inequalities indexes of Internet access and mobile phone ownership to measure use of ICT goods, accounting for the digital divide in Brazil. The inequality indexes are also split according to main determinants using four nationally representative survey data from 2005 to 2013. Results indicate that the digital divide among individuals is decreasing quite fast among Brazilians over time. However, there is room for policies of mass access to ICT goods based on mobile Internet broadband access. In addition, digital illiteracy, evaluated by lack of education, is one of the main determinants of the digital divide in the country, especially among elderly individuals. 相似文献

Managers of remote and wilderness environments have been among the last to accommodate the needs of tourists with mobility-disabilities – partly because of the physical difficulties and expense of doing so, but also due to a wider desire and mandate to preserve the natural and wilderness character of such areas. This research explores the extent to which those with mobility-disabilities desire enhanced access to natural areas. Do they share the same desires and values with respect to wilderness and access as the able-bodied? This paper reports upon a survey of over 400 residents and tourists, some with mobility-disabilities and some able-bodied, and compares their attitudes with respect to the development of various forms of motorised access to wilderness environments. Significant differences were found between the two groups in terms of their desire for greater access and also in how they view the impacts of such development. The group with mobility-impairments expressed a stronger desire for enhanced access in such environments. The environmental values of both groups were also examined using the revised New Ecological Paradigm scale, however no significant differences were found between the groups. The implications for tourism providers and wilderness managers are discussed. 相似文献
