减税降费对企业“获得感”影响研究——基于认知偏差视角

针对近年来减税降费政策力度很大但部分企业获得感不及预期现象,本文尝试从认知偏差视角予以解释,并运用东部某省企业问卷调查数据进行实证检验。结果发现:税费负担下降不能完全解释企业减税降费获得感变化,非税因素通过锦上添花雪中送炭两种效应影响获得感。建议协同推进财税、环保、金融等领域降成本改革,全方位增强企业获得感,同时立足全球经济竞争税收竞争视角,进一步降低我国宏观税负特别是大口径宏观税负水平。

Health Care Competition and Antibiotic Use in Taiwan

Antibiotic resistance, a negative externality of antibiotic use, is a growing threat to public health. Health care competition may encourage antibiotic use because receiving an antibiotic is a form of ‘quality’ for many patients. This paper examines the effect of market concentration on antibiotic use in a large, nationally‐representative data set from Taiwan. Moving from the 75th percentile to the 25th percentile of market concentration is associated with 6.6 per cent greater antibiotic use. We control for leading market‐level confounds, including population density and community health. We also show that the correlation is robust using fixed effects for patients, physicians and diagnoses. We document the correlation between antibiotic use and patient retention, which suggests a mechanism for this result. Finally, we show that strict regulation of antibiotics reduces but does not eliminate the effect of competition on antibiotic use.     

Momentum Profitability and Market Trend: Evidence from REITs

This study investigates Real Estate Investment Trusts’ momentum returns in different market states, and explains the momentum phenomenon with a risk-based dividend growth theory of Johnson (Journal of Finance 57:585–608, 2002). Our results show that momentum returns of REITs are higher during up markets. This study finds that winners’ dividend/price ratios are higher than those of losers, and momentum returns are positively correlated with the difference between winners’ and losers’ dividend/price ratios. We also find that momentum returns are higher after the legislation change of REITs in 1992, and that dividend/price ratios of REITs are also higher after 1992, suggesting that a persistent shock to REIT’s dividend/price ratios in 1992 partly explains REITs’ higher momentum returns after 1992. In sum, results of this study suggest that momentum returns of REITs can be jointly explained by a time-varying factor (market state) and a cross-sectional variance in dividend yields.

An empirical study of commercialization performance on nanoproducts

Along with the trend toward the convergence between nanotechnology and other disciplines, the commercial application and the diffusion of Nan products have drawn much attention. The successful commercialization of nanoproducts is based not only on R&D breakthroughs but also on the products' attributes and the consumers' needs. However, no research has yet been carried out to investigate the effect of performance and importance on nanoproducts. The aim of this study is to discuss and evaluate the commercialization performance of nanoproducts from consumer perspectives. The importance?performance analysis (IPA) approach was used to construct a series of nanoproducts' importance attribute and performance evaluation maps to identify areas for improvement. The empirical data were compiled in a structural consumer questionnaire-based survey from consumer perspectives across different nanoproducts. Respondents were required to identify nanoproducts' innovative characteristics and the performance differences of their attributes. Both innovation characteristics and product attribute dimensions as representing nanoproduct innovations were further weighted in terms of their perceived importance and their performance. As a consequence, the proposed approach in this study is to understand how to integrate consumers' perceived importance into performance, with particular concern on the identification of market opportunities into the commercialization of nanoproducts. In addition, this study enables nanotechnology firms to develop nanoproduct technologies and to strategically market them based on their attributes and performance, thus leading to the achievement of their commercialization and the creation of a successful long-term, performance-based competitive strategy.     

Dynamic information disclosure

We study dynamic information disclosure by a sender attempting to persuade a partially informed receiver to take an action. We consider vertical and horizontal information. With vertical information, an optimal disclosure plan is static. If the sender cannot commit to the disclosure plan, there exists a simple Markov equilibrium with sequential disclosure. Shrinking the time interval to zero gives rise to full disclosure almost instantly. With horizontal information, the sender often benefits from sequential disclosure. Assuming partial commitment and a special receiver‐type space, a Markov equilibrium exists and almost instant full disclosure arises in the limit.
