When used in those spheres of life where attaching a price tag or making an economic calculus is impossible or loses any meaning, markets usually under perform and disappoint. In addition to empirical shortcomings of markets, the unrealistic theoretical assumption and poor predictive and explanatory value of neoclassical equilibrium theory provides fertile ground for critics of the institution of markets. Complexity theory provides a theoretical framework that enables us to analyze the role of markets from a radically different perspective than that offered by neoclassical equilibrium theory and, therefore, to reach very different conclusions about the role of markets in industrialized economies.  相似文献

Abstract

Heterogeneity of perceptions is a neglected issue in market segmentation studies. Only recently parametric approaches toward modeling segmented perception-preference structures such as combined MDS and Latent Class procedures have been introduced. A completely different nonparametric method is based on topology-sensitive vector quantization (VQ) for consumers-by-brands-by-attributes data. It maps the segment-specific perceptual structures into bar charts with multiple brand positions exhibiting perceptual distinctiveness or similarity. A brief introduction into the VQ methodology is followed by a sample study on three urban destinations competing on the world travel markets. City images serve as the underlying behavioral constructs. Preferential data are based on respondents' comes-closest-to-ideal-city judgments and incorporated into the perceptual positions of city profiles. Perceptual charting works on two levels of aggregation named prototypes and perceptual sub-structures. The results demonstrate how this method prevents the analyst from drawing erroneous conclusions due to uncontrolled aggregation.  相似文献

This paper combines research on the measurement of disclosure quality and the measurement of share price anticipation of earnings to produce a new test of the usefulness of the information disclosed in management discussions of operations and financing for predicting future earnings. Market-Based Accounting Research has shown that earnings changes are anticipated and impounded in prices well before the financial year for which earnings are reported. This price anticipation leads to downward biased earnings response coefficients (ERCs) in the commonly estimated regression model of returns on contemporaneous earnings changes. We exploit predictable differences in the biasedness of the ERC estimate across firm-years to test the hypothesis that share prices are better informed when the annual report contains a detailed discussion of the firm's operations and financing. Our results suggest that such voluntary disclosure may have been useful in predicting future earnings changes. The effect would appear to be strongest (1) in models that examine one-period-ahead and two-period-ahead share price anticipation and (2) when we employ a disclosure index that captures forward-looking information.  相似文献

Neoliberalism has transformed markets supplying public goods. Analysis of five real-world Australian markets reveals the eligibility rules for access and ongoing participation, interaction of participants, the role of intermediaries and government, the extent of competition, complex regulatory regimes shaping and controlling these markets, and key market outcomes. Contrary to neoliberalism's free market rhetoric and the view promulgated by mainstream economics, a spectrum of market configurations and governance regimes were found along with participation being highly dependent on technology access and skills, market outcomes inconsistent with policy rhetoric, market interrelationships posing adverse cumulative impacts, and government is strongly interventionist through multiple roles.  相似文献

In this paper we analyse the indirect effects of the boom in horticultural exports in Senegal on child schooling. The export boom has caused a dramatic increase in female off-farm wage employment, which led to increased female bargaining power in the household. We investigate the causal effect of female wage income on primary school enrolment. We develop a collective household model with endogenous bargaining power to show that, if women have higher preferences for schooling than men, the impact of female wage income on school enrolment will be the result of a positive income effect, a negative labour substitution effect and a positive empowerment effect. We address the question empirically using original household survey data from Senegal. We use different econometric techniques and show that female off-farm wage income has a positive effect on primary school enrolment for both boys and girls, and that female empowerment is specifically important for the schooling of girls. Our results imply that the horticultural export boom in Senegal has indirectly contributed to the second and third Millennium Development Goals of universal primary education and elimination of gender disparities in primary education.  相似文献

We examine human capital's contribution to economy-wide technological progress through two channels – imitation and innovation – innovation being more skill-intensive than imitation. We develop a growth model based on the endogenous ability-driven skill acquisition decision of an individual. It is shown that skilled human capital is growth enhancing in the “imitation-innovation” regime and in the “innovation-only” regime whereas unskilled human capital is growth enhancing in the “imitation-only” regime. Steady state exists and, in the long run, the economy converges to the world technology frontier. In the diversified regime, technological progress raises the return to ability and generates an increase in wage inequality between and within groups – consistent with the pattern observed across countries.  相似文献

The most striking feature of the current economic situation in Spain is the huge unemployment rate, above 25 percent. From an orthodox perspective, we suggest that this unemployment is the result of a highly inflexible labor market, which needs to be reformed by introducing flexibility measures. The paper argues, however, that labor market reforms introduced since the early 1980s, allowing an excessive use of temporary employment contracts, have had perverse effects on the Spanish economy. They have affected negatively not only aggregate demand and supply, but also income distribution. The emergence of these market reforms helps explain the current rate of unemployment as well as the deep impact of the global financial crisis on overall Spanish economic activity.  相似文献

对1978年改革开放以来林业财政政策分两阶段进行评述。1978~1992年,我国的林业财政投入政策、林业税收政策、林业财务政策对促进林业快速发展发挥了重要作用,主要表现在:推进了森工企业改革,推进了造林绿化,林业事业体系建设逐步完善。但也存在税收负担重、未形成有效投入体系、财务政策追逐目标不当等问题。1992年至今,积极的林业财政政策使我国生态建设体系明显加强,森林资源保护重点加强,林业产业体系更趋完善。但在面对林业急需发展的实际仍显投入不足,林业税收政策尚未达到应有的优惠程度,林业财务政策仍需改革等方面仍需改进。  相似文献

In this paper, we study how central bank transparency influences the formation of money market expectations in emerging markets. The sample covers 25 countries for the period from January 1998 to December 2009. We find, first, that transparency reduces the bias (the difference between the money market rate and the weighted expected target rate over the contract period) in money market expectations. The effect is larger for countries with no exchange rate peg and countries with low income. Second, an intermediate level of transparency is found to have the most favorable influence on money market expectations: neither complete secrecy nor complete transparency is optimal. Finally, all subcategories of the Eijffinger and Geraats (2006) index lead to a smaller bias in expectations, with political transparency having the largest effect.  相似文献

随着劳务派遣制的普遍使用,企业中正式员工与劳务派遣员工身份"差序格局"的矛盾逐渐凸显出来,对劳务派遣员工的工作投入造成了重要影响。本文从个体和组织两个层面探索了劳务派遣员工工作投入的影响因素,在此基础上分析了身份"差序格局"对劳务派遣员工工作投入的影响机理,并针对劳务派遣员工的实际情况提出了构建其高工作投入机制的应对策略。  相似文献
