我国公共租赁房运作模式的实践与探索——基于部分城市公共租赁房运行情况的比较分析

本文以北京、上海、杭州等公共租赁房起步较早的大中城市为研究对象,从公共租赁房的界定、投资主体、供应对象、房源筹集、资金渠道、租金管理、土地供应与政策支持、物业管理、准入与退出等9个方面进行剖析比较,总结这些城市在公共租赁房建设实施过程中的经验及存在的问题,探索有效的解决方法,以期为我国公共租赁房的进一步发展提供参考。     

城市科技企业孵化器网络形成与演变研究

城市科技企业孵化器网络是基于城市范围内的各类科技企业孵化器和高校院所、科技中介机构、政府相关部门、各种投融资机构等相关主体相互结网形成的一种战略性服务型经济组织,它是科技企业孵化器发展到一定阶段后的一种具体表现形态。城市科技企业孵化器网络的形成与演变是一个动态的连续发展过程,一般经历孕育生成期、快速发展期、成熟稳定期等三个发展阶段。其发展与演化不是偶然的,而是存在于网络内部和外部的各种驱动因素相互作用的结果,各种驱动因素在不同发展阶段的影响作用和效果都有所差异。     

电力直接交易试点若干问题分析与建议

开展电力用户与发电企业直接交易试点,是我国电力市场化改革的一项重大举措。但从试点情况看,直接交易试点仍存在一些问题,某种程度上影响直接交易试点工作的开展。对直接交易的目的、交易实质、榆配电价、结算等进行了探讨,提出继续推进直接交易试点,需要统一认识,坚持正确的方向,坚持积极稳妥、试点先行,坚持统筹兼顾、协同推进。     

淮河流域农业干旱对粮食产量的影响分析

干旱是制约我国粮食生产的主要因素,严重影响了农产品的生产和粮食安全。以受干旱影响程度较重的淮河流域为研究对象,通过对历史旱情资料的统计分析表明：流域农业干旱灾情随年代的发展逐渐加重,且不同行政区域之间存在较大差异。利用相关数据实证检验了1999～2008年间流域内农业干旱灾害对粮食生产的影响。结果表明,农业干旱灾害对粮食生产具有明显的影响,并提出了相应的政策建议。该分析结果可为淮河流域农业防灾减灾体系建设和粮食安全提供些许的参考和借鉴。     

Dissecting Word-of-Mouth's Effectiveness and How to Use It as a Proconsumer Tool

Companies are increasingly relying on alternative promotional activities, such as word-of-mouth communication (WOM), to reach their target markets. From a consumer protection perspective this may be troubling, as consumers may not always be aware of what is commercially motivated WOM and what is not. Based on a synthesis of the literature, this article develops the first practitioner-friendly model, which explains WOM's effectiveness as an information source for consumers and why it is a powerful tool for nonprofit organizations and government agencies. Then nine recommendations are developed to help nonprofit organizations and government agencies use WOM more effectively as a proconsumer tool. This is the first article to conceptualize proconsumer WOM rather than naturally occurring WOM or commercial WOM and to specifically focus on WOM to protect and educate consumers. The study paves the way to an untapped research area; that of proconsumer WOM by nonprofit organizations and government agencies.     

Pricing models of equity swaps

This article provides a generalized formula for pricing equity swaps with constant notional principal when the underlying equity markets and settlement currency can be set arbitrarily. To derive swap values using the risk‐neutral valuation method, the swap payment is replicated at each settlement date by constructing a self‐financing portfolio. To obtain the foreign equity index return denominated in the domestic or in a third currency, equity‐linked foreign exchange options are used to hedge the exchange rate risk. It is found that if the swap involves international equity markets, then the swap value contains an extra term which reflects the currency hedging costs. This methodology can easily be applied to price various types of equity swaps simply by modifying the specifications of the model presented here as required. © 2003 Wiley Periodicals, Inc.

THE PRICING OF JOB CHARACTERISTICS WHEN MARKETS DO NOT CLEAR: THEORY AND POLICY IMPLICATIONS*

This article examines nonsequential search when jobs vary with respect to nonpecuniary characteristics. In the presence of frictions in the labor market, the equilibrium job distribution need not show evidence of compensating wage differentials. The model also generates several pervasive features of labor markets: unemployment and vacancies, apparent discrimination, and market segmentation. When workers are homogeneous, restrictions on the range of job offers decrease welfare and cannot reduce unemployment. However, when workers have heterogeneous preferences, such restrictions may lower unemployment, and can even lead to a Pareto improvement in welfare. We consider the impact of policies banning discrimination and regulating working conditions.     

Urban economics and development

China’s policy of opening the door to foreign business has sometimes aroused excessive expectations. Both in China and abroad, overoptimism has now been replaced by a more realistic appraisal of what can be achieved in economic terms. Nonetheless, Deng Xiaoping’s aim of quadrupling industrial and agricultural output¹ by the year 2000 is still being pursued. Urban regions have been allocated a key role in this as the powerhouse of development. In the light of regional economic analyses,²this article examines whether the intended economic reforms go far enough to enable the conurbations to perform this function.     

Who Controls US?

Berle and Means asserted that US corporations typically have dispersed shareholders; their evidence did not support this conclusion. Today, 59.74% of US corporations have ‘controlling shareholders’ who hold at least 10% of the shares; 24.57% are controlled and managed by a family; 16.33% are controlled by a widely‐held financial institution; 13.55% are controlled through family trusts. In all size ranges, the USA has more corporations controlled by families than by financial institutions. In almost all size ranges, it has a higher percentage of family‐controlled corporations than any of next four largest economies.
