Does intellectual monopoly stimulate or stifle innovation?

This study develops an R&D-based growth model with vertical and horizontal innovation to shed some light on the current debate on whether patent protection stimulates or stifles innovation. We analyze the effects of patent protection in the form of blocking patents. We show that patent protection changes the direction of innovation by having asymmetric effects on vertical innovation (i.e., quality improvement) and horizontal innovation (i.e., variety expansion). Calibrating the model and simulating transition dynamics, we find that strengthening the effect of blocking patents stifles vertical innovation and decreases economic growth but increases social welfare due to an increase in horizontal innovation. In light of this finding, we argue that in order to properly analyze the growth and welfare implications of patents, it is important to consider their often neglected compositional effects on vertical and horizontal innovation.     

Market Power in Chinese Taipei: Laws, Policies and Treatments

The experience of Chinese Taipei shows that opening up a previously protected market to new entrants can be a more effective and reliable way to enhance competition than regulating the behavior of dominant or monopolistic firms. Moreover, when opening up the market, the liberalizing measures adopted by government should be market-structure-neutral. That is, it should not try to dictate the direction and results of market competition. A more pressure-resistant mechanism should be designed to deal with market power, taking the form of a regime that is cross-sector, independent and collective in its decision-making, such as has been the case with Chinese Taipei's Fair Trade Commission.

我国城乡居民边际消费倾向的再估算

收入分配是否影响居民消费需求以及产生何种影响,取决于边际消费倾向是否同收入水平相关。文章基于可变参数的状态空间模型,实证估计了我国城乡居民在1978~2012年间的边际消费倾向,估算结果显示:我国城乡居民边际消费倾向在1978~2012年间与收入水平间呈现"倒U"型变动关系;但相比而言,农村居民边际消费倾向要低于同期城镇居民。     

安徽农地承包经营权规模化流转调查与思考

近年来,安徽省农地承包经营权流转面积稳步增加,规模逐渐加大,对促进农业增产和农业现代化效果显著,对农民增收和工业化、城市化发展也有积极影响。农地规模化流转及经营完善了农业家庭承包的经营结构,在发展现代农业中可以与农户经营互荣共存。促进农地规模化流转要注意保护农民土地承包权益,与农村剩余劳动力转移相结合。     

并购中的价格锚定:金融创新还是价值掠夺--基于上市公司并购重组的案例分析

高并购溢价一直是理论界和监管层关注的重点问题。本文以上市公司高并购溢价为例,深入分析了并购交易中锚定价格的动机及其经济后果。研究发现,上市公司的支付对价与并购标的业绩承诺现值之间的差额是融资购买股权的费用,并不是并购标的未来现金流的折现。这主要是上市公司利用信息不对称将融资购买股权的费用直接锚定在股价中,引导外部投资者看好此次并购,最终上市公司大股东通过减持掠夺了中小股东的利益。本文给监管层的政策建议是要规范并购重组中的定价问题,并详细披露相关的信息,以降低与外部投资者之间的信息不对称。

Agility index in the supply chain

To achieve a competitive edge in the rapidly changing business environment, companies must align with suppliers and customers to streamline operations, as well as working together to achieve a level of agility beyond individual companies. Consequently, agile supply chains are the dominant competitive vehicles. Embracing agile supply chain requires asking some important questions, namely: what exactly is agility and how can it be measured? Moreover, how can agility be effectively achieved and enhanced? Due to the ambiguity of agility assessment, most measures are described subjectively using linguistic terms. Thus, this study develops a fuzzy agility index (FAI) based on agility providers using fuzzy logic. The FAI comprises attribute’ ratings and corresponding weights, and is aggregated by a fuzzy weighted average. To illustrate the efficacy of the method, this study also evaluates the supply chain agility of a Taiwanese company. This evaluation demonstrates that the method can provide analysts with more informative and reliable information for decision.     

Population Density and Infrastructure Development

A model is proposed with the following features: (1) there is a publicly accessible transport technology, which is more advanced when there is more specialized labor in it; (2) a high population density facilitates the development of the transport technology; (3) an improved transport technology facilitates a finer division of labor, which in turn increases per capita income. These features are compatible with the phenomena of economic development described by Boserup in 1981. It is also shown that, provided the infrastructure sector can charge the users, and individuals are free to choose jobs, the competitive equilibrium will be Pareto-optimal.
