To examine how intellectual property rights protection affects trade, growth, and welfare, I develop a two-country R&D-based growth model in which final goods firms in both countries determine the range of imported varieties in the overall use of intermediate inputs. I show that strengthening patent protection in either country increases the range of imported varieties of intermediate goods and stimulates economic growth in the country that strengthened patent protection. Moreover, I also show that the Nash equilibrium level of patent protection is stronger than the globally optimal level of patent protection.  相似文献

In this article, we investigate whether there is adverse selection and/or moral hazard in credit guarantee schemes for small and medium enterprises (SMEs) in Japan. As credit guarantee corporations cannot distinguish low risk from risky borrowers, credit guarantee schemes typically attract a larger proportion of risky borrowers, which results in inefficient resource allocation. Using bank-level data, we analyse whether the default rate is positively associated with the ratio of guaranteed loans to total loans, and find that the data are consistent with an adverse selection and/or moral hazard hypothesis. Further analysis shows that the relationship is stronger for 100% coverage than for 80% coverage, indicating that the ‘20% self-payment’ requirement somewhat mitigates the problem, but not enough to eliminate it altogether.  相似文献

The main purpose of this paper is to examine accounting information which can be of poor quality for some industries because uniform regulation applies to all. However, there is a strong demand for reliable accounting data even when the quality of the data is poor. Consistent with this premise, I show that among young NASDAQ listings the valuation coefficient on BVE is higher and that on earnings is not lower for intangible-intensive ventures than for other firms. I also show that GAAP OCF provides additional information that enhances the quality of earning information. This results in a shift in valuation weight from BVE to earnings for intangible-intensive young NASDAQ listings. However, these phenomena do not appear for intangible-intensive S&P 500 firms listed on NYSE. My results suggest that variations in the demand for reliable financial data affect the valuation coefficients on earnings and BVE.  相似文献

This paper addresses a question raised by Jan de Vries' on the relationship between industriousness and the rise of the market in East Asia. Was the growing industriousness in Tokugawa Japan, as de Vries suggests, a substitute ‘for the absence of markets’? The examination refers to two versions of Chayanov's peasant farm model and their empirical relevance to the Tokugawa agrarian history, with special reference to the formation of labour‐intensive peasant farming (Akira Hayami's version of an industrious revolution), product specialisation, and the markets for production factors, land, and labour. Its implications for the Great Divergence debate are also discussed.  相似文献

This study investigates the intermediary functions and the farmers’ perspectives in the development and implementation of agri-environmental schemes in Shiga Prefecture of Japan by employing the innovation journey analysis and the statistical analysis. The innovation journey analysis demonstrates that the prefectural government served as an ‘innovation intermediary’ to: (1) provide a clear vision of sustainable agriculture for farmers and other actors, (2) create and reinforce both technological and market niches and (3) develop actor networks involving local actors. It also identifies the following roles of the Japan Agricultural Cooperatives (JAs) and the specialist wholesaler as innovation intermediaries to: (1) develop new farming materials such as fertilizers, (2) translate and deliver practical farming knowledge for farmers and (3) establish the market of environmental-friendly rice. Statistical analysis uncovers that farmers more appreciated the supports from the JAs than those from other intermediaries to participate in the schemes. Complemented by the innovation journey analysis, our findings suggest that the keys to increasing farmers’ participation in the schemes include a clear vision and economic incentives for farmers as well as the coordination among intermediaries who have different expertise.  相似文献

New Rice for Africa (NERICA) was developed by the Africa Rice Center by crossing high-yielding Asian rice (Oryza sativa L.) with locally adapted African rice (Oryza glaberrima Steud.). Community-based seed production of NERICA varieties was introduced in a village in central Benin in 2006 through seed dissemination projects. It was reported that high-adoption rates of these varieties were mainly due to high demand by development projects for seed dissemination, and to incentives (i.e. selling the rice seed at a higher than local market price to a local extension service) for farmers to grow NERICA varieties. A follow-up survey was undertaken after the seed dissemination projects ended to examine the change in the cultivation of NERICA varieties. About half of the farmers had ceased cultivation of NERICA varieties in 2011. The reasons for abandonment were the combined effects of reduced seed demand and low yields, which were attributed to a lack of access to credit and training on NERICA cultivation practices. The majority of the farmers did not abandon rice cultivation, but grew other high-yielding varieties, including one aromatic variety for which there was market demand. We conclude that to avoid immediate reductions in the adoption of new varieties after projects are terminated and to enhance agricultural sustainability, the varieties should be introduced in conjunction with appropriate group training on their cultivation, and the project should target farmers who do not have off-farm businesses. Furthermore, access to credit should also be enhanced, and the marketability of the varieties should be assessed.  相似文献

This article examines whether adverse selection or moral hazard could be induced by rate regulation, which prohibits insurance companies from considering some attributes of drivers in setting premiums. Using an individual data set from a heavily regulated automobile insurance market, we arrived at several conclusions, as follows. First, no evidence of adverse selection or moral hazard is found in general: conditional on all the variables observed by insurer, the null hypothesis of independence between risk and coverage is not rejected at reasonable levels of statistical significance. Second, this result is robust in the sense that it holds under several empirical procedures and different definitions of risk and coverage. Third, we find that unobserved variables do not induce adverse selection: the null hypothesis that consumers in risky regions are more likely to purchase insurance is tested against the alternative and rejected. Our study supports the view that the adverse selection phenomenon exists only to a very limited extent in this market.  相似文献

Objective: Patients with constipation account for 3.1 million US physician visits a year, but care costs for patients with irritable bowel syndrome with constipation (IBS-C) or chronic idiopathic constipation (CIC) compared to the general public have received little study. The study aim was to describe healthcare utilization and compare medical costs for patients with IBS-C or CIC vs matched controls from a community-based sample.

Methods: A nested case-control sample (IBS-C and CIC cases) and matched controls (1:2) for each case group were selected from Olmsted County, MN, individuals responding to a community-based survey of gastrointestinal symptoms (2008) who received healthcare from a participating Rochester Epidemiology Project (REP) provider. Using REP healthcare utilization data, unadjusted and adjusted standardized costs were compared for the 2- and 10-year periods prior to the survey for 115 IBS-C patients and 230 controls and 365 CIC patients and 730 controls. Two time periods were chosen as these conditions are episodic, but long-term.

Results: Outpatient costs for IBS-C ($6,800) and CIC ($6,284) patients over a 2-year period prior to the survey were significantly higher than controls ($4,242 and $5,254, respectively) after adjusting for co-morbidities, age, and sex. IBS-C outpatient costs ($25,448) and emergency room costs ($6,892) were significantly higher than controls ($21,024 and $3,962, respectively) for the 10-year period prior. Unadjusted data analyses of cases compared to controls demonstrated significantly higher imaging costs for IBS-C cases and procedure costs for CIC cases over the 10-year period.

Limitations: Data were collected from a random community sample primarily receiving care from a limited number of providers in that area.

Conclusions: Patients with IBS-C and CIC had significantly higher outpatient costs for the 2-year period compared with controls. IBS-C patients also had higher ER costs than the general population.  相似文献
