有限理性视角下区域内地方政府博弈行为的演化与稳定

文章从有限理性视角出发,运用演化博弈理论对区域内地方政府间的博弈行为进行分析.研究发现:在外部条件既定的情况下,区域内同质、异质地方政府的博弈存在各自不同的演化路径和稳定策略;并且实现稳定策略的路径不是经典博弈理论下的简单线性路径,而是复杂的非线性路径,存在关键性的阀值.这意味着,对区域内地方政府间博弈行为的调节需要依博弈参与者的不同属性和博弈的演化路径来进行,并且有效地调节思路需在博弈的外部求解.

Rational and behavioural predictors of pre-retirement cash-outs

Given the worldwide concern that individuals are not saving sufficiently for retirement, many governments are taking action to try and rectify this tendency. A key focus area is implementing policies to dissuade individuals from accessing accumulated retirement funds when changing jobs. While traditional economic theories assume that individuals act rationally and make optimal decisions without outside intervention, current policy interventions support behavioural theories of decision-making where sub-optimal choices occur due to limitations in human decision-making. Therefore, interventions are based on the assumption that individuals act irrationally. Despite these interventions, many individuals still access their funds suggesting that current interventions may not be sufficiently aligned with the factors influencing decision making in this environment.The main research objective of this study was to test empirically both rational and behavioural factors that could potentially influence retirement preservation decisions, to determine which factors were the best predictors of whether an individual preserved funds when changing jobs. A research instrument was designed using a combination of existing psychometric measures and customised questions to form an analytical survey. This was used to test the factors that predicted the preservation decisions of a sample of 256 academic and non-academic personnel at a tertiary education institution in South Africa.The study found that behavioural factors play an important role in predicting preservation decisions. In particular, behavioural factors related to bounded rationality, due to the computational complexity of the decision-making environment, emerged as important explanatory variables, indicating that interventions such as decision support and guidance may assist individuals in making optimal decisions.     

Quality‐Speed Competition in Customer‐Intensive Services with Boundedly Rational Customers

We consider a system in which two competing servers provide customer‐intensive services and the service reward is affected by the length of service time. The customers are boundedly rational and choose their service providers according to a logit model. We demonstrate that the service provider revenue function is unimodal in the service rate, its decision variable, and show that the service rate competition has a unique and stable equilibrium. We then study the price decision under three scenarios with the price determined by a revenue‐maximizing firm, a welfare‐maximizing social planner, or two servers in competition. We find that the socially optimal price, subject to the requirement that the customer actual utility must be non‐negative, is always lower than the competition equilibrium price which, in turn, is lower than the revenue‐maximizing monopoly price. However, if the customer actual utility is allowed to be negative in social optimization, the socially optimal price can be higher than the other two prices in a large market.     

Strategic Capacity Management When Customers Have Boundedly Rational Expectations

In retailing industries, such as apparel, sporting goods, customer electronics, and appliances, many firms deploy sophisticated modeling and optimization software to conduct dynamic pricing in response to uncertain and fluctuating market conditions. However, the possibility of markdown pricing creates an incentive for customers to strategize over the timing of their purchases. How should a retailing firm optimally account for customer behavior when making its pricing and stocking/capacity decisions? For example, is it optimal for a firm to create rationing risk by deliberately under stocking products? In this study, we develop a stylized modeling framework to answer these questions. In our model, customers strategize over the timing of their purchases. However, customers have boundedly rational expectations in the sense of anecdotal reasoning about the firm's fill rate, i.e., they have to rely on anecdotes, past experiences, or word‐of‐mouth to infer the firm's fill rate. In our modeling framework, we distinguish two settings: (i) capacity commitment, where the firm commits to its capacity level in the long run, or (ii) the firm dynamically changes it in each season. For both settings, within the simplest form of anecdotal reasoning, we prove that strategic capacity rationing is not optimal independent of customer risk preferences. Then, using a general form of anecdotal reasoning, we provide sufficient conditions for capacity rationing to be optimal for both settings, respectively. We show that the result of strategic capacity rationing being suboptimal is fairly robust to different valuation distributions and utility functions, heterogeneous sample size, and price optimization.

关于广义远达问题的适定性

设C是实Banach空间X中有界闭凸子集且0是C的内点,PC(·)是关于C的Minkowski泛函.设K是Banach空间X中非空闭的有界相对弱紧子集.对X中的点x,称最大化问题maxC(x,K)为适定的是指存在唯一的(z)∈K使得pC((z)-x)=uC(x,K)和每一满足limnn→∞pC(zn-x)=uC(x,K)的序列{zn}(∈)K均强收敛到(z),其中uC(x,K)=supz∈KpC(z-x).在C是严格凸和Kadec的假定下,证得了使得最大化问题maxC(x,k)为适定的所有x∈X的全体组成的集合X0(K)是X中的剩余集.进一步,如果关于Pc(·)的凸性模是严格正的,K是X中闭的有界子集,证明了集X\X0(K)是X中的σ-多孔集.这些本质地推广和延拓了包括De Blasi等,Fitzpatrick,Panda和Kapoor,Li和作者等人结果在内的近期相应结果.
