Who should sell stocks?

Never selling stocks is optimal for investors with a long horizon and a realistic range of preference and market parameters, if relative risk aversion, investment opportunities, proportional transaction costs, and dividend yields are constant. Such investors should buy stocks when their portfolio weight is too low and otherwise hold them, letting dividends rebalance to cash over time rather than selling. With capital gains taxes, this policy outperforms both static buy‐and‐hold and dynamic rebalancing strategies that account for transaction costs. Selling stocks becomes optimal if either their target weight is low or intermediate consumption is substantial.     

What explains the value premium? The case of adjustment costs,operating leverage and financial leverage

This paper empirically examines and compares the different theoretical predictions on how adjustment costs, operating and financial leverage influence the value premium. Consistent with Ozdagli (2012), financial leverage plays a dominant role, supported by adjustment costs (which represent the degree of investment irreversibility). Specifically, the observed value premium is driven by the financial leverage differences between value and growth firms, partially neutralized by investment irreversibility. The relation between the value premium and investment irreversibility is contrary to the intuition in Zhang (2005) and Cooper (2006). Operating leverage does not significantly influence the value premium.     

行政审批改革与制度性交易成本——基于效率评价的视角

制度性交易成本是经济主体为遵守制度规定而产生的非生产性成本,行政审批改革通过提高经营效率、节约时间成本、降低资金成本和促进行业竞争四种途径降低制度性交易成本。本文通过对我国地市级面板数据的实证分析后发现,行政审批改革可以有效降低地区制度性交易成本;当行政审批改革发生在营商环境相对较差的中西部城市、距离省会城市较近的城市以及当城市获得法律支撑时,能够更显著地降低当地制度性交易成本。本文据此提出如下政策建议:深化行政审批改革,减少不必要的审批事项;健全改革激励机制,确保政策的贯彻与落实;通过机构设置、法律规定、权责划分等进行配套措施改革。     

Considering the nuclear option: Hidden benefits and social costs of nuclear power in the U.S. since 1970

Although burning fossil fuels has environmental consequences, many countries have switched away from nuclear power in favor of fossil-fuel fired electricity production after incidents at Three Mile Island, Chernobyl, and Fukushima. This study estimates the substitution between nuclear and fossil-fuel fired electricity generation in the United States. Using an event-study framework, we leverage nuclear plant openings from 1970 to 1995 and forced nuclear plant outages from 1999 to 2014. Plant openings (nuclear outages) reduce (increase) monthly net coal-fired generation by approximately 200 GWh, implying a considerable reduction (increase) in emissions. We find that the substitution between nuclear and coal is not one-to-one, as has been assumed in prior literature. After establishing these stylized facts, we explore the potential underlying forces driving the observed substitution between coal and nuclear.     

Institutional Economics as Theory of Policy Change: Impact of Past Policy Failures on Present Policy

Social scientists have developed several theories for understanding or evaluating policy change over time. Since all costs or benefits are not internalized owing to positive transaction costs, policymaking is always implemented under cost underestimation conditions and, therefore, is imperfect. I call this trait policy failure in this article. Furthermore, I show that a new framework combining the social costs approach and the legal/economic approach in institutional economics is suitable and can be applied to evaluating how past policy failures affect present policy, providing as an example the Fukushima nuclear disaster in Japan.     

The cost of unconventional gas extraction: A hedonic analysis

We focus on identification and estimation of potentially negative environmental impacts of unconventional natural gas extraction on property values in the United States and advance previous research by contributing new data and new identification strategies for isolating these potential impacts. Our study area consists of two counties in Pennsylvania that are home to large amounts of unconventional natural gas extraction but are otherwise isolated from other resource extraction industries or large urban areas. We deploy parametric, semi-parametric, and matching hedonic regression models that include recent quasi-experimental methods and, in contrast to previous research and much popular intuition, we fail to find robust significance that negative environmental externalities of natural gas extraction are manifested in nearby property values. While there may be plausible risks associated with unconventional natural gas extraction, we do not find consistent evidence to suggest that these risks significantly affect nearby property values.     

Did APEC's Trade Facilitation Action Plans deliver the goods?

This paper uses new data to examine whether APEC achieved its aim of reducing trade transaction costs by 10% over the 2002–2010 period. An inversion of the familiar gravity model makes it possible to infer trade costs based on the observed pattern of trade and production across economies. Analysis of trade costs calculated in this way shows that although intra- and extra-APEC trade costs fell during the sample period, they did not do so substantially more quickly than elsewhere in the world. Indeed, the region taken as a whole did not meet the 10% reduction goal. However, a considerable number of individual economies not only met the goal, they greatly exceeded it. Consistent with their outward oriented development strategies and leverage of global and regional value chains, some APEC economies saw very rapid falls in their trade costs over the 2002–2010 period, Viet Nam being a standout performer. Overall, about one third of the forum's membership for which consistent data are available met or exceeded the 10% reduction goal. APEC's two Trade Facilitation Action Plans can therefore be seen as having had mixed records of success.     

Staff turnover costs: In search of accountability

The nature of staff turnover accounting procedures in a labour intensive context has been examined by conducting interviews with twenty eight managers in large three to five star hotels and two theme parks. It was found that the main staff turnover accountability procedures adopted involve monthly departmental reporting of staff turnover percentage levels and also the conduct of exit interviews. A degree of staff turnover costing was noted, although this practice was not extensively applied. Most interviewees supported the notion of allocating staff turnover costs to those operating departments experiencing the turnover. A muted form of this practice was observed in one hotel, however most interviewees had never contemplated or heard of the practice. Agency theory has been utilized as a framework for structuring a range of observed and potential staff turnover accountability relationships.     

The relationship between satisfaction and loyalty: A mediator analysis

This study proposes a multiple mediation model to analyze the relationship between satisfaction and loyalty. The study's contribution to the literature is to examine, empirically, the main antecedents and determinants of this endogenous variable in greater depth. Thus, the research fills a gap in the literature through its analysis of the mediating role of perceived switching costs and the perceived lack of attractiveness of alternative offerings. This study applies variance-based structural equation modeling via partial least squares to a sample of 785 customers from 74 insurance companies in the service sector. The results show that perceived switching costs – to a greater extent – and the perceived lack of attractiveness of alternative offerings – to a lesser extent – are significant mediators in the relationship between satisfaction and loyalty.
