关于当代悖论性的三个哲学论证

当代的悖论性可以从三个方面来把握:在时间上,当变化过于快速,且是为了资本获利而变成人为设计的东西时,变化就意味着停滞;在空间上,经济全球化本质上是世界同质化的过程,但同质性却以异质性的面目出现,异质性被用来服务于同质性,空间的悖论由此产生;面对时间和空间的悖论,我们需要乌托邦想象,但我们的乌托邦想象却要以反乌托邦的形式出现,这就是所谓乌托邦的悖论。不管是乌托邦还是反乌托邦,作为一种政治策略,它都是人们的经验和思想所不能缺少的一个维度。     

博弈论的理性概念与理性的悖论

博弈论的理性概念和经济学的理性概念是一脉相承的,通常被表述为期望效用最大化准则和占优准则。从形式上看,这些准则并不涉及自利性和利他性、个体理性和群体理性之间的关系。但是,将它们运用于不同主体之间的策略性互动时,会产生“理性选择的不合理性”的悖论。“纽科姆问题”表明,没有自利性的博弈论理性概念并没有摆脱经济学理性概念的矛盾。     

Correlated equilibria in homogeneous good Bertrand competition

We show that there is a unique correlated equilibrium, identical to the unique Nash equilibrium, in the classic Bertrand oligopoly model with homogeneous goods and identical marginal costs. This provides a theoretical underpinning for the so-called “Bertrand paradox” as well as its most general formulation to date. Our proof generalizes to asymmetric marginal costs and arbitrarily many players in the following way: The market price cannot be higher than the second lowest marginal cost in any correlated equilibrium.     

Employee development and voluntary turnover: testing the employability paradox

The employability paradox is a concern among employers. It states that development activities enhancing employees' employability also increase the risk for employee turnover. This study examined this paradox and probed the relationship between six development activities and voluntary turnover mediated by perceived employability. We tested both a turnover‐stimulating path via perceived external employability (i.e. perceived job alternatives with other employers) and a retention path via perceived internal employability (i.e. perceived job alternatives with the current employer) by using two‐wave longitudinal data from 588 employees. The results put the turnover risk into perspective: only upward job transition positively influenced turnover via perceived external employability. Also, the retention path via perceived internal employability was not supported: several development activities were positively related with perceived internal employability, but perceived internal employability did not influence turnover. We did, however, find a direct retention effect of skill utilisation. Overall, the results downplay the employability paradox.     

Combining Probability Distributions by Multiplication in Metrology: A Viable Method?

In measurement science quite often the value of a so‐called ‘output quantity’ is inferred from information about ‘input quantities’ with the help of the ‘mathematical model of measurement’. The latter represents the functional relation through which outputs and inputs depend on one another. However, subsets of functionally independent quantities can always be so defined that they suffice to express the entire information available. Reporting information in terms of such a subset may in certain circumstances require aggregating probability distributions whose arguments are interrelated quantities. The option of aggregating by multiplication of distributions is shown to be susceptible of yielding inconsistent results when the roles of inputs and outputs are assigned differently to the quantities. Two alternatives to this practice that do not give rise to such discrepancies are discussed, namely (i) logarithmic pooling with weights summing to one and (ii) linear pooling, of which the former appears to be slightly more favourable for applications in metrology. An example illustrates the inconsistency of results obtained by distinct ways of multiplying distributions and the manner in which these results differ from a logarithmically pooled distribution.     

The Transfer Problem and Intergenerational Allocation in an Overlapping Generations Model

We investigate the transfer problem between two countries in the steady state in a one-sector overlapping generations model and explain how transfers should be shared between the young and old generations of the donor country and allocated across the generations of the recipient country. Except at the golden rule of capital accumulation, the ratios of the burden and distribution of transfers between the young and old generations affect welfare. We obtain the following results. First, the sharing of the transfer burden in the donor country depends on the relative size of two effects, namely, a negative direct effect and a positive indirect effect. If the former exceeds the latter, it is preferable for the donor country to allocate all of the transfer burden to the old generation and vice versa. Second, from the viewpoint of welfare maximization, it is preferable for the recipient country to distribute all of the transfers to the young generation. In contrast to the existing literature, these results suggest that the setting whereby the young generation of the donor country defrays all transfer costs may not be justifiable from the viewpoint of donor welfare maximization.     

Coastal Urban Planning in The ‘Green Republic’: Tourism Development and the Nature–Infrastructure Paradox in Costa Rica

This article examines coastal urban planning in Costa Rica vis‐à‐vis the country's values in the areas of sustainable tourism and community development, focusing on the city of Jacó. I argue that an anti‐urban tourism development strategy, swift coastal urban development and weak planning have nurtured a nature–infrastructure paradox: when people are brought closer to nature without proper urban and governmental infrastructure, this causes social and environmental damage. To assess this paradox and understand local perceptions of development, I analyzed lengthy semi‐structured interviews and survey responses in San José and Jacó in this study. Research methods also encompassed analysis of current tourism planning institutions and regulations, tourism media coverage and reports, real estate data, participant observation of planning and community meetings and activities, and observations of the built and natural environmental conditions in Jacó and its surroundings. The findings show jurisdictional fragmentation, regulatory weaknesses, complexity, poor coordination, slow action, and incoherent planning and development, leading to environmental degradation and socio‐spatial inequities. A more balanced approach to planning and development would seek to improve environmental health and socio‐spatial equity in tandem, by nurturing and advancing both nature and infrastructure development. Lessons from Jacó have global resonance, given the expansion of the worldwide tourism and second‐home/retirement‐housing industries, their recent concentration in urban coastal destinations of developing countries, and the fragility of these socio‐ecological systems.     

The Five Paradoxes of Meaningful Work: Introduction to the special Issue ‘Meaningful Work: Prospects for the 21st Century’

In this introduction to the Journal of Management Studies Special Issue on Meaningful Work, we explain the imperative for a deeper understanding of meaningfulness within the context of the current sociopolitical environment, coupled with the growing use of organizational strategies aimed at ‘managing the soul’. Meaningful work remains a contested topic that has been the subject of attention in a wide range of disciplines. The focus of this Special Issue is the advancement of theory and evidence about the nature, causes, consequences, and processes of meaningful work. We summarize the contributions of each of the seven articles that comprise the Special Issue and, in particular, note their methodological and theoretical plurality. In conclusion, we set forth a future research agenda based on five fundamental paradoxes of meaningful work.     

国企性质的“诺思悖论”解释:从利润的角度

市场经济体制下,国企既表现出国家性,又表现出企业性.国企利润能让我们更加深刻地认识国企性质与国家行为,它作为国家租金的一种表现形式,因其国家偏好而成为国企问题产生的重要根源.当国企利润与产出达到均衡点时,国企的国家性与企业性就能达到完美均衡,国企的自身发展与功能和作用的发挥就能达到最佳状态.     

The microeconomics of the developmental paradox: on the political economy of food price policy

A longstanding puzzle in comparative economics is the ‘developmental paradox’, the tendency for government support for agriculture to increase with national income and to decrease with the proportion of economic activity and of the population in agriculture. This paper offers a microeconomic explanation for that puzzle. It establishes analytically the microeconomic basis for coalition alignments with respect to food price policy, then numerically simulates the comparative static effects of alternative food policies on coalition structure. A parsimonious household model applied to a heterogeneously endowed society demonstrates how variation in individual welfare effects might beget distinct coalitions in the debate over food price policy and how those policies are inextricably linked to land, population, and technology policies in food agriculture. Moreover, coalition alignments on particular policy debates are path-dependent. In particular, food price policy creates its own political support.
