对经济学的"手"理论的述评

通过综合分析经济学理论关于"看不见的右手"(市场)、"看得见的左手"(政府)、"看得见的右手"(企业)和"看不见的左手"(权力及利益集团)的功能、缺陷及发挥各只"手"的功能所必需的约束条件,可以看出,要实现资源的优化配置、经济增长和社会和谐,各只"手"必须各司其职,发挥其长处、规避其缺陷,在其有效边界内运作而不是畸形发育,并处理好"四只手"之间的比例、结构和均衡关系。     

A missing link in modeling : The future of time-use as an illustration

A Theory of Action is formulated based on the intentionality of actions. The transformation rules from the new theory to system dynamics were developed and the methodology was then applied to certain problems of future time-use. The modeling approach used is holistic and it requires a meta-system to system dynamics in order to produce quantitative results.     

Hedonic adaptation and the role of decision and experience utility in public policy

Many economists are becoming supportive of ‘soft’ paternalistic interventions that help people to avoid common decision errors without curtailing individual autonomy. To identify when such interventions could be beneficial, and to assess their success, requires a welfare criterion. However, traditional preference or choice-based criteria cannot serve this function because they assume that whatever people choose makes them better off. An alternative criterion that bases welfare on happiness rather than choice avoids this problem but has several of its own drawbacks. Most notably, people often adapt to serious chronic health conditions, and exhibit high levels of happiness, even though both those with and those without the condition agree that it is much preferable to be healthy. After reviewing different lines of research that shed light on the pros and cons of these alternative welfare criteria, we argue that no simple criterion based on either concept can surmount these problems. Instead, evaluations of welfare will inevitably have to be informed by a combination of both approaches, patched together in a fashion that depends on the specific context.     

Asset pricing with loss aversion

The use of standard preferences for asset pricing has not been very successful in matching asset price characteristics, such as the risk-free interest rate, equity premium and the Sharpe ratio, to time series data. Behavioral finance has recently proposed more realistic preferences such as those with loss aversion. Research is starting to explore the implications of behaviorally founded preferences for asset price characteristics. Encouraged by some studies of Benartzi and Thaler [1995. Myopic loss aversion and the equity premium puzzle. The Quarterly Journal of Economics 110 (1), 73–92] and Barberis et al. [2001. Prospect theory and asset prices. Quarterly Journal of Economics CXVI (1), 1–53] we study asset pricing with loss aversion in a production economy. Here, we employ a stochastic growth model and use a stochastic version of a dynamic programming method with an adaptive grid scheme to compute the above mentioned asset price characteristics of a model with loss aversion in preferences. As our results show using loss aversion we get considerably better results than one usually obtains from pure consumption-based asset pricing models including the habit formation variant.     

Prisoner’s Dilemmas, Cooperative Norms, and Codes of Business Ethics

Prisoner's dilemmas can lead rational people to interact in ways that lead to persistent inefficiencies. These dilemmas create a problem for institutional designers to solve: devise institutions that realign individual incentives to achieve collectively rational outcomes. I will argue that we do not always want to eliminate misalignments between individual incentives and efficient outcomes. Sometimes we want to preserve prisoner's dilemmas, even when we know that they systematically will lead to inefficiencies. No doubt, prisoner's dilemmas can create problems, but they also create opportunities to practice the cooperative norms that make market institutions possible in the first place. An ethical market culture, I argue, benefits from the presence of prisoner's dilemmas. I first consider standard approaches for solving prisoner's dilemmas. I then argue for the value of prisoner's dilemmas. Finally, I show the significance of this argument for advocating codes of business ethics.     

Capital market efficiency and the relationship between equity returns, interest rates, and monetary aggregates in Australia

This paper examines the efficiency with which the Australian share market incorporates new information relating to interest rates and the monetary aggregates into share prices. It finds a strong relationship between medium term government security yields and equity returns although little relationship could be found between unanticipated changes in the monetary aggregates and share returns. Furthermore, the interest rate relationship involved long lags and suggests inefficiency in stock market pricing in Australia.     

Agency through Development: Hausa Women's NGOs and CBOs in Kano,Nigeria

ABSTRACT

Analyzing the participation of Hausa women in religiously influenced nongovernmental organizations (NGOs) devoted to development work provides critical insights into the complex intersection of gender, religion, class, culture, and politics and economics. Based on interviews with leaders and employees of various NGOs, including community-based organizations (CBOs), in Kano, Nigeria, in 2010–11, this in-depth case study provides important examples of how various types of NGOs navigate political pressures when it comes to funding; it recognizes the understudied importance of women's labor contributions in the context of the development apparatus in Africa; it highlights the role of women as progenitors rather than benefactors of economic development; and it illustrates the unique role that faith-based organizations (FBOs) can and do play in terms of reaching certain marginalized segments of the population.

How price complexity takes its toll: The neglected role of a simplicity bias and fairness in price evaluations

Marketing managers commonly employ complex price plans. Surprisingly, limited and conflicting evidence reports how customers perceive and react to complex prices. This study examines perceptions about price complexity and shows that customers tend to prefer simple prices. Two experimental studies show that perceived price complexity negatively affects customer perceptions of price fairness and influences product choice because customers negatively evaluate the transparency of the firm's pricing practices and infer higher total prices. Customers comparing alternate offerings may therefore prefer simple over complex prices, even when the latter are less expensive. Study results suggest limiting price plan variations positively affects customer inferences about transparency and fairness, and thus customer choice.
