基于动态面板数据模型分析FDI的环境效应

外商直接投资在对中国经济增长起到积极推动作用的同时,我们也不可忽视其可能会对我国环境造成的影响。文章通过构建环境污染综合指数,并且以东中西部为三个横截面建立动态面板数据模型来分析外商直接投资对各个地区环境的影响。结果显示,外商直接投资和东部中部地区的环境污染指数之间有正相关关系,和西部地区的环境污染指数之间是一个负相关关系。     

An Application of the Dynamic Network DEA Model: The Case of Banks in Taiwan

ABSTRACT

In this study, we apply the dynamic network slack-based measure data envelopment analysis model (DNSBM) to measure the efficiency of Taiwanese banks during the period 2005–11. Using the network structure, we define intellectual capital creation capability as one of the production stages. In order to capture the dynamics of the transformation process, the nonperforming loans and loan loss reserves are defined as carryover items. This study offers sufficient information for managers to understand not only the overall performance of their banks but also the efficiency of each production stage and the dynamic changes of the overall and divisional efficiencies.     

Efficiency in overlapping generations economies with longevity choices and fair annuities

When individuals can influence their life-expectancies and save in annuities, suboptimal savings result from the lack of incentives to choose the optimal longevity, even when annuity returns can be made contingent to longevity-related choices. Specifically, the golden rule steady state maximizing the representative agent utility cannot be attained as a competitive equilibrium under laissez-faire, even with actuarially fair annuities contingent to longevity-enhancing choices. In order to decentralize through markets the golden rule, longevity-enhancing expenditures need to be taxed if the steady state old-age consumption exceeds the annuitized capital return, and subsidized otherwise—the government budget being balanced through lump-sum transfers or taxes. Interestingly, with positive population growth the expected net contribution is negative when longevity-enhancing expenditures are taxed, and positive when subsidized.     

Consumer microflow experiences

This research explores relatively short, low‐intensity flow states, called microflow and demonstrates that they differ from their longer, more complex deepflow variants with regards to antecedents. As an advancement to flow theory, we demonstrate that the ideal condition to elicit microflow is when skills are slightly higher than the difficulty of the task. Importantly, despite being relatively shorter, microflow experiences still have a strong positive influence on consumer attitudes. Our research also advances theory by demonstrating that the two dimensions of microflow have different relationships with the level of difficulty and consumer attitudes. We discuss both theoretical and practical implications.     

The effect of activity identity fusion on negative consumer behavior

Negative consumer behavior is an important research topic as it explores consumer behaviors that threaten a brand's image and financial stability. However, prior research offers conflicting findings on whether a strong consumer‐brand relationship hurts or protects a brand after a market disruption or a brand transgression. To provide clarity on this issue, this work argues that disrupting the consumer‐activity relationship motivates consumers to reaffirm and protect their identity, thereby leading to negative consumer behavior. The data reveal that, after a brand‐initiated market disruption, consumers with high activity identity fusion are more likely to spread negative word‐of‐mouth, boycott the brand, and avoid repurchasing the brand in the future. Moreover, the data suggest that high brand identity fusion protects the brand during market disruptions; therefore, prior conflicting results may be due to the fact that the consumer‐activity relationship was not accounted for. Theoretically, this work establishes that consumers' relationship with their consumption activities has significant impacts on consumer behavior. Brand managers and marketers are urged to develop strategies that focus on strengthening the consumer‐brand relationship and not the consumer‐activity relationship.     

How collaborative routines improve dynamic innovation capability and performance in tourism industry? A path-dependent learning model

Current results of direct relationships between collaboration and innovation capability on performance in tourism contexts are inconsistent. This research is to uncover roles of collaborative routines on promoting relationships between internal and service innovation capabilities as two distinct mechanisms, and performance. The study also examines the contingent effect of knowledge search on performance. Survey data from 181 samples from the Thai tourism industry are gathered for analyses. Findings demonstrate that knowledge search and internal innovation capability have a direct impact on performance, whereas the effect of service innovation capability on performance is significant only in the presence of collaborative routines.     

房地产企业工程造价的管理与控制

Bond Pricing with a Time‐Varying Price of Risk in an Estimated Medium‐Scale Bayesian DSGE Model

New Keynesian model in which households have Epstein–Zin preferences with time‐varying risk aversion and the central bank has a time‐varying inflation target can match the dynamics of nominal bond prices in the U.S. economy well. The model generates a large steady‐state term spread and its fitting errors for bond yields are comparable to those obtained from a nonstructural three‐factor model, and one‐third smaller than in models with a constant inflation target or risk aversion. Including data on interest rates has large effects on variance decompositions, making investment technology shocks much less important than found in other recent papers.     

Organic Food at the Point of Purchase: Understanding Inconsistency in Consumer Choice Patterns

The organic food category, while still small in terms of world food production, has continued to grow in many markets in the developed world. This article focuses on understanding the barriers and facilitators to purchasing organic food at the final hurdle: the point of purchase (POP). A qualitative study has identified seven factors that influence buyer behavior at the POP, and these are consumer intention to purchase organic food when entering the retail outlet; habit; availability; false assumptions; visibility and access of organic food; visual and olfactory cues; and price. These can often be the final hurdle to consumers choosing (or not) organic food at the POP.     

What's in a tip? The creation and refinement of a restaurant-tipping motivations scale: A consumer perspective

According to Segrave (1998), since the late 1800s, the study of tipping has provoked debate in a range of abstract dimensions such as economics, sociology, and psychology. To date, the research on the topic has been largely qualitative in nature, while addressing motivating themes (service, social norm, and future service considerations) in isolation from one another. Following a thorough examination of the literature, there is a definite lack of research on the development and testing of a more holistic quantitative scale aimed at identifying the motivational Gestalt driving actual consumer tipping behavior. Therein lies the major theoretical contribution of this study, namely the development and testing of a Tipping Motivations Scale, which over two separate analyses, supports a number of drivers of consumer tipping motivation.In this study, exploratory and confirmatory factor analyses were conducted to test the empirical dimensions of consumer tipping motivations. The results obtained indicate a reasonable fit between the data and the proposed model across both analyses. This was repeated on two separate occasions and the results largely remained consistent. The findings point to the key role of service in driving the consumer's decision to tip. Other important factors included social conformity, the issue of future visitation, and server actions. Further research is needed to explore whether these dimensions remain constant among other sample groups and across different tipped professions.
