自从1998年起,中国成品油市场定价机制已经进行了四次改革,市场定价将是未来的发展趋势。但是鉴于现在成品油市场尚处于寡头垄断的市场结构,完全放松管制可能出现无法预料的严重后果,采用基于Agent的计算经济学的方法,建立了基于信念学习的中国汽油市场模型,并重点分析了垄断溢价形成的影响因素,以及消费者的刚性需求和收入约束对消费者福利的影响。通过对不同原油价格水平下汽油市场的模拟,得到了描述消费者生存率的二次方程。通过建立虚拟变量模型,发现当消费者决策受收入约束时,油价、收入和刚性需求对其福利的边际影响都相应变小。模型的结果对燃油税政策的制定有一定的参考意义。 相似文献

Empirical evidence suggests that most firms operate in imperfectly competitive markets. We develop a search-matching model between wholesalers and retailers. Firms face search costs and form long-term relationships. Price bargain results in both wholesaler and retailer mark ups, which depend on firms' relative bargaining power. We simulate the general equilibrium model and explore the role of product market search frictions for business cycles. We conclude from the simulation exercise that incorporating product market search structure and shocks improve the standard real business cycle model to reproduce US business cycle fluctuations. 相似文献

Self-classification is used as an a priori approach to tourist typology and market segmentation. However, skepticism still surrounds its ability to incorporate the multidimensionality of tourist behavior. This study seeks to empirically verify the efficacy of a single-item self-classification approach. The robustness of this self-classification measure is examined by comparing it to a data-driven multidimensional psychographic approach in terms of its ability to predict the behaviors of tourists toward food-related destination consumption. Results suggest that the single-item self-classification approach performs equally well as the psychographic approach in segmenting food-related consumption behaviors. The implications and limitations of this study are also discussed. 相似文献

This study focuses on what drives technology-driven companies to engage in risk-taking behavior by serving new markets. Building on the behavioral theory of the firm and prospect theory, this study suggests that technology-driven organizations tend to respond to past performance rather than future possibilities. Using a sample of 5312 video games from 362 game developers, the results reveal that market performance trend and market performance variability have opposing effects on risk-taking behavior: while a positive market performance trend negatively influences a company's tendency to venture into new markets, a high-degree of market performance variability tends to positively influence new market entry. The study also finds opposite results for expert performance trend and expert performance variability: companies with consistently positive expert evaluations are more likely to enter into new markets, while variability in expert evaluations has a negative effect on new market entry. Furthermore, the effects of expert performance trend and variability are conditional on market performance trends. Finally, the results suggest that companies that venture into new markets tend to choose relatively similar markets if these companies are suffering from a negative market performance trend or a negative expert review trend. 相似文献

Keynes (1930) and Samuelson (1965) proposals open the possibility of matching predictability and efficiency, as evidenced by the seminal study by Fisher (1930). Recent findings suggest that the foreign exchange market gradually incorporates relevant information allowing the formation of prices in a rational manner but not randomly. Models of exchange rate by term based on asset valuation suggest that the inclusion of risk in the spot rate increases the degree of predictability. The results show that after incorporating an accurate measure of risk, predictability of medium term foreign exchange rate increases. 相似文献

We examine how industry competition affects firms’ choice of short‐term debt. We find that the percentage of short‐term debt is positively related to industry concentration at low levels of concentration, and inversely related to industry concentration at higher levels of concentration. This nonlinear relation is stronger in industries where firms are either more homogeneous or compete more aggressively. Moreover, we find that firms with shorter‐maturity debt are less aggressive than their rivals in the product market. The overall evidence suggests that although financial contracts alleviate agency problems, they exacerbate the risk of predation. 相似文献

森林碳汇市场的形成经历了自愿行动、试验交易、经验总结和强化认识以及规范、发展等四个阶段.自从它形成之后,国内外的学者纷纷对其进行研究,他们发现计量体系不完善、相关市场制度和规则不完善、法制不完善、市场信息的难以获得以及较高的交易成本等因素阻碍了中国森林碳汇市场的发展.文章建议通过建立控制温室气体排放的强制性政策、建立统一的森林碳汇计量体系和标准、制订相应的法规条例、加强对森林碳汇理论的宣传和研究以及降低交易成本等措施来促进中国森林碳汇市场的发展. 相似文献
