招投标竞争:汶川地震灾后部分重建专项资金分配运作的探索

汶川灾后重建专项资金的分配应该与重建项目有机契合,部分灾后重建资金可以探索招投标竞争方式分配运作.以招投标竞争方式分配运作部分灾后重建专项资金具有重要的战略意义.以招投标竞争方式分配运作灾后重建专项资金,关键要建立与完善招投标的程序及其相应的比选指标体系.为此,我们应该按照政府引导市场、市场公开交易、交易规范运作、运作统一监管的思路,完善灾后重建专项资金招投标竞争分配运作的制度安排.     

Modelling risk premia in CO2 allowances spot and futures prices

This article analyzes the modelling of risk premia in CO₂ allowances spot and futures prices, valid for compliance under the EU Emissions Trading Scheme (EU ETS). Similarly to electricity markets, a salient characteristic of CO₂ allowances is that the theory of storage does not hold, as CO₂ allowances only exist on the balance sheets of companies regulated by the scheme. The main result features positive time-varying risk premia in CO₂ spot and futures prices, which are strictly higher for post-2012 contracts (€6–9/ton of CO₂) than for Phase II contracts (€0–6/ton of CO₂). Contrary to Benth et al.'s (2008) for electricity markets, a positive relationship between risk premia and time-to-maturity is found in the EU ETS. As for relative differences between CO₂ futures and spot prices, CO₂ futures traded between + 1% (December 2008 contract) and + 33% (December 2014 contract) above spot prices during February 2008–April 2009. Contrary to Bessembinder and Lemmon (2002) for the electricity market, a positive relationship between risk premia and the variance/skewness of CO₂ spot prices is found. The futures-spot bias to the EU ETS explains around 1–6% of the variance of CO₂ futures premia.     

论我国政府主导型国企制度变迁深化的必然及约束

政府主导型制度变迁是国有企业制度变迁的路径依赖之一，这是由客观的社会经济条件决定的。国企制度在同一轨迹上的变迁在取得巨大收益之后已进入边际效益递减、制度容量饱和的阶段，向更高效 水平的制度演进已成为必然。然而，政府主导型制度变迁也面临着政治竞争、交易费用、政治家效用函数、效率与稳定两难选择及其他体制性问题的约束。制度的进一步创新需要政治体制的相应调整、需要坚持政府主导型变迁方式，需要其他外部力量的影响。     

Corporate Governance and the Goal of the Firm: In Defense of Shareholder Wealth Maximization

This essay is based on my keynote address at the 2016 annual meeting of the Eastern Finance Association. I propose that misunderstandings about the traditional model of corporate governance, with its emphasis on shareholder wealth maximization, contribute to negative societal attitudes about corporations. I discuss the implications of shareholder wealth maximization for other corporate stakeholders, the dangers of deviating from shareholder wealth maximization, and the roles that the media and the government play in the governance of corporations.

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.
