Reviewing Oates' insights in a repeated game setting

This paper analyzes the optimal assignment of public good policies to layers of a federal system in a repeated game setting. Under a centralized regime, public goods are financed jointly across regions, and a federal legislature decides on the regional quantities. Under a decentralized regime, public goods are financed locally, and governments play a non-cooperative provision game. We find that a centralized (decentralized) regime is more likely to provide the efficient public good policies in case spillovers are small (large).

Pseudo empirical likelihood method in the presence of missing data

In this paper, we propose an estimator for the population mean when some observations on the study and auxiliary variables are missing from the sample. The proposed estimator is valid for any unequal probability sampling design, and is based upon the pseudo empirical likelihood method. The proposed estimator is compared with other estimators in a simulation study.

城市地价评估中的地质环境问题

地价评估通常考虑的影响因素主要有社会因素、经济因素、政策法规，以及地块的地理位置，而对城市的地质环境的影响考虑较少。本文就城市地质环境问题，研究了其对土地价格评估的作用，以及在地价评估中的量化关系。

Entry and Exchanges of Cost Information

The literature on exchanges of information has ignored firms' entry decisions. Yet, the Federal Trade Commission recently expressed concerns that exchanges of information in business-to-business electronic platforms would adversely impact entry and, thus, consumers. When entry decisions are endogenized in a competitive Cournot model with cost uncertainty, we find results that contrast sharply with current thinking on the welfare consequences of information sharing.     

Indigenous livelihoods, slash-and-burn agriculture, and carbon stocks in Eastern Panama

Improved crop–fallow systems in the humid tropics can simultaneously sequester atmospheric carbon emissions and contribute to sustainable livelihoods of rural populations. A study with an indigenous community in eastern Panama revealed a considerable biophysical potential for carbon offsets in small-scale slash-and-burn agriculture through longer fallow periods, improved fallow management, secondary forest development, and agricultural intensification. Based on soil and biomass carbon measurements, estimated annual sequestration rates amount to 0.3−3.7 t C ha^− 1 yr^− 1. Despite such potential, the economic benefits of initiatives aimed at sequestration of carbon in the community are likely to be rather unequally distributed within the community. Heterogeneity in livelihood strategies and uneven asset endowments among households – factors often overlooked in the ongoing carbon and sustainable development debate – are expected to strongly affect household participation. Indeed, only the better-endowed households that have also managed to diversify into more lucrative farm and non-farm activities are likely to be able to participate in and thus benefit from improved crop–fallow systems that capture carbon. Economic, ethical, institutional, and technical concerns need to be taken into account when designing community carbon management and investment plans.

Designing trust

The decision making process in technological development, with its underlying suppositions of certainty and controllability, contributes to fomenting social resistance to technology rather than trust among social actors. Those underlying suppositions are in disaccord with values and world views expressed by the new social movements. These movements, which form part of today’s civil society and are critical of many modern technologies, tend to hold an implicit view of technology as a social experiment under uncertainty. The tendency of the current design activity of basing design decisions on criteria, like engineering efficiency, defined as objective, is contributing to this lack of trust in the very process of decision making, which many social actors are currently demonstrating. Technology, however, depends on sustained public trust. Future technology design has therefore to take into account, as one of its basic functions, the creation of trust among actors.     

浅谈英语教学改革中对学生英译汉技巧的培养

英语教学改革要求我们要把提高学生的英语应用能力放在第一位，教师要在学生的学习过程中起到引导和辅助的作用。在英译汉的过程中，教师不能只生硬地传授译文，而是要把英译汉的规律进行归粪总结，得出一些象数学公式一样的翻译技巧，将其传授给学生，让学生在学习中加以实践运用，达到以不变应万变的良好效果，进而提高学生的英语应用能力。
