Economies of scale and trade policy: The median voter model revisited

Why do some political economy models perform so poorly in predicting actual trade policy? Do scale economies provide the missing puzzle to our understanding of the anti-trade bias? By integrating economies of scale in production, this paper theoretically reinstates the median voter model as in Mayer [Mayer, W. (1984). Endogenous tariff formation. The American Economic Review, 74, 970–985] as a suitable political economy model in predicting trade policy. The modified model generates the scope for the anti-trade bias and predicts that sometimes economic, rather than political, considerations may lead to restrictive trade.

本文以我国上市公司为研究对象,选取2009年被ST的上市公司作为财务危机样本组,共61家, 同时选取与财务危机组同行业,资产规模在10%差异之内的61家非财务危机上市公司作为配 对样本,共计122家(61组)上市公司的财务数据进行研究。从这61组中随机选取31组配对样 本作为学习样本组,用来构建财务困境预测模型,另外30组样本作为检验样本组,用来检验 预测模型的有效性。     

美联储前瞻性指引对新兴市场国家的溢出效应研究

基于前瞻性指引溢出效应的相关理论,选取17个代表性新兴市场国家为研究对象,运用面板向量自回归(PVAR)模型实证分析美联储前瞻性指引对新兴市场国家的溢出效应.结果表明:美联储前瞻性指引在短期内对新兴市场国家金融市场具有一定的冲击,在长期内对新兴市场国家经济增长存在滞后的正向作用.新兴市场国家应采取应对策略,做好风险识别和预警,加强预期管理,增强货币政策协调和合作,有效防范和化解外溢影响.

新兴技术演化的整体性分析框架：“三要素多层次”共生演化机理研究

新兴技术演化是在技术自身、市场需求、配套环境、企业能力等众多要素的共同作用下完成的。本文对企业能力、市场需求和配套环境与新兴技术之间的共生演化机理进行了探讨,提出了一个新兴技术"三要素多层次共生演化"模型,旨在通过研究本模型为揭示新兴技术演化过程的特征提供一个多视角的整体性分析框架,为进一步从不同层面、不同角度深入研究新兴技术演化提供理论指导。     

Regular economies with ambiguity aversion

We consider a family of exchange economies with complete markets where consumers have multiprior preferences representing their ambiguity aversion. Under a linear independence assumption, we prove that regular economies are generic. Regular economies exhibit enjoyable properties: odd finite number of equilibrium prices, local constancy of this number, local differentiable selections of the equilibrium prices.Thus, even if ambiguity aversion is represented by non-differentiable multiprior preferences, economies retain generically the properties of the differentiable approach.     

Derivatives Usage in Emerging Markets Following the GFC: Evidence from the GCC Countries

In this article, we avail of International Accounting Standards IFRS 7 to investigate the usage and motivation of hedging by firms in the Gulf Cooperation Council (GCC) countries (Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates). The results of our panel and cross-sectional data logistic regressions indicate a focus on foreign exchange exposure, interest rates risk, and commodity risk in this region. We find that the use of hedging instruments in this region is also influenced positively by the firm’s size and, to a lesser degree, positively by the firm’s gearing ratio and negatively by its propensity to growth. The level of activity, nevertheless, remains lower than is the case for firms globally.

El efecto fin de mes en los principales mercados accionarios latinoamericanos

In equity markets, it is common to find calendar anomalies, which have been the subject of several studies in recent decades, even some of them showing that over time these anomalies have disappeared. In this context, this paper analyzes one of these anomalies, the end-of-the-month effect, in both return and volatility in six Latin American stock markets, namely Brazil, Mexico, Chile, Colombia, Peru and Argentina during the period of 1993-2011. The importance of the evidence for the existence of this anomaly is to allow testing whether the effect has been disappearing over time. The findings of this research show the existence of positive abnormal returns and abnormal volatilities on days associated with the change of months for most of the countries under analysis. This research was performed according to three different periods defined in the literature to analyze the impact of the end-of-the-month effect. This research not only examines the key indexes of each market, but also the individual stocks of each, giving a much larger and demanding sample, which can lead to better conclusions about the existence of the phenomenon. Also, the transaction volume analysis is included to validate some hypotheses related with the high cash flow in the turn-of-month period.
