MEASURING THE OPERATIONAL EFFICIENCY OF COMMERCIAL BANKS IN NAMIBIA

This paper examines the efficiency of commercial banks in Namibia using the standard econometric frontier approach. Although two aspects of efficiency (scale and scope) receive our attention, the emphasis is on the latter which pertains to whether a firm produces as efficiently as it possibly can, given its size. Our results indicate that substantial economies of scale exist in commercial banking in Namibia. This will tend to suggest that commercial banks in Namibia can increase their efficiency by increasing their current scale of operation. The results for scope economies show that the current level of input combination does not make for maximum efficiency as sufficient scope exists for a more efficient combination of inputs. We believe this will reduce operating costs in the industry and stimulate efficiency.     

“万村千乡”推广悖论及其解决方案

在农村消费市场存在差异的条件下，全国范围的以行政补贴和市场推广相结合的“万村千乡”推广方式将面临“推广悖论”，即工程的普遍服务职能与企业追求利润的目标之间的冲突，进而可能会造成财政补贴资金的浪费。应在不同区域采用不同的推广策略：发达地区农村，应以企业自主经营为主；具有一定消费市场潜力但企业开拓成本还比较高的地区，应行政补贴和市场推广相结合；尚不具备经营条件的农村地区，应加强基础设施建设，并提高农民收入水平，待时机成熟后再逐步推进。     

Stability and Segregation in Group Formation

This paper presents a model of group formation based on the assumption that individuals prefer to associate with people similar to them. It is shown that, in general, if the number of groups that can be formed is bounded, then a stable partition of the society into groups may not exist. (A partition is defined as stable if none of the individuals would prefer be in a different group than the one he is in.) However, if individuals' characteristics are one-dimensional, then a stable partition always exists. We give sufficient conditions for stable partitions to be segregating (in the sense that, for example, low-characteristic individuals are in one group and high-characteristic ones are in another) and Pareto efficient. In addition, we propose a dynamic model of individual myopic behavior describing the evolution of group formation to an eventual stable, segregating, and Pareto efficient partition.

人民银行员工激励机制设计的进化博弈分析

博弈理论是当代主流经济学发展最迅速和影响最大的分支学科之一。其中,进化博弈理论由于引入了“进化稳定策略”（ESS）的概念,有效解决了博弈双方有限理性的现实问题,在解释经济管理现象时更具说服力和生命力。本文结合人民银行实际,通过构建进化博弈理论的复制动态模型,试述人民银行员工激励路径的选择及机制设计的有关问题。     

Environmental protection versus economic growth

This paper presents and analyses the differences in the eco-models implemented worldwide （such as whether and how carbon taxes being ＂recycled＂）, or in their efficiency parameters （inconsistent parameter values that account for different results）. This is the assumption that a real tradeoff exists between the production of environmental goods. The present article empirically proves that something must be given up in order to gain something else, and once equations are specified to trace out the path of the economy over time, the natural economic formulation of such equations will embody the notion of economic and bio-tradeoffs.     

话语民主理论下可持续发展中的公民参与

可持续发展目标的追求需要公民的集体判断，公民参与作为可持续发展的基本原则之一，有利于实现可持续发展的目标，也是为避免“公地悲剧”尴尬局面的必然选择。从话语民主理论的角度来看，我国可持续发展进程中存在着公民参与可持续发展的不完善性和公民淡漠的问题，以及官僚式的独白现象。因此，要构建公共能量场确保可持续发展政策执行过程公民话语的正当性和合法性，实行一些人的对话参与可持续发展，通过“重复性实践”使可持续发展中的公民参与制度化。

China's regional income disparityAn alternative way to think of the sources and causes1

Using data on China's provincial economies for the period 1978–2005, we decomposed the causes and factors that have contributed to inter‐regional per capita income disparity. Variance in capital per employee and variance in capital elasticity are found to be the two main sources of income disparity while the employment–labour force ratio is shown to be an important factor in containing the rise of income disparity. An analysis on inter‐regional factor reallocation effects reveals their relatively small and insignificant contributions to overall growth performance. It is also discovered that capital has in most years flowed in the right direction to pursue higher marginal productivity across provincial economies. Inter‐provincial labour movement, on the other hand, had not displayed significant equilibrating effects until institutional reforms started to allow freer inter‐regional labour mobility in later years. Generally, we conclude that market‐oriented factor mobility has played a crucial role in equalizing factor returns as well as enhancing growth efficiency across regions.

城市旅游标志物的确定及其结构化

针对旅游者对将要访问的城市比较陌生、选择旅游对象物时出现茫然的现象，为了更好地服务于旅游者，基于旅游行政管理的立场，提出了城市旅游标志物概念，认为其核心成员的确定需要基于遗产性、规模性、便捷性和公益性4个原则，并给出了核心成员、支持成员和外围成员的认知结构。
