我国期货市场亟需期货投资基金

我国期货行业自进入21世纪以来取得了飞速发展,无论品种规模还是成交量都已位居世界前列,然而,在国外已经成为期货市场主力的期货投资基金在我国却难觅其踪。期货投资基金可以优化和改善投资组合,规避股市系统性风险,实现专家理财保护中小投资者利益。实际上,从市场规模、运作现状、风险控制、资金充裕度以及证券投资基金在我国发展的成功经验来看,我国已基本具备设立期货投资基金的基础。但期货投资基金毕竟是一个高风险的投资工具,国内对它的研究还比较薄弱,法律体系和监管机制仍待完善,产品的种类和活跃程度仍待加强,在基金公司的设立方式上仍需谨慎选择,对于期货投资基金亟需的高端综合型人才的培养都是我国急需解决的问题。     

The disintegrating Canadian labour market? The extent of the market then and now

Abstract.  Analysis of real wages for three occupations in 13 Canadian cities for 1901–50 suggests Canada had a national labour market at least until 1950. However, analysis of real wages for 10 Canadian cities for 1971–2000 yields little evidence favouring integration of Canada's regional labour markets. The apparent lack of labour market integration reflects a weakness of an approach that assumes markets are in equilibrium. Unemployment rates after 1970 suggest that some regional markets may be characterized by excess labour supply. Analysis of relative provincial unemployment rates yields evidence consistent with local labour force adjustment to changing labour market conditions. JEL classification: E24, J61     

我国资本市场的国际化与B股市场的发展定位

对一国而言,资本市场国际化是资本市场开放的最高阶段,其中包括筹资的国际化、投资的国际化和交易工具与机构的国际化。发展中国家在资本市场国际化的进程中适合采用渐进式开放模式。我国B股市场属于对外开放的国际化部分,但近年来由于发展取向的不明确,使其长期处于低迷萎缩状态。我国的B股市场应定位于外币证券市场,逐步完成其国际化进程。为此,要扩大B股市场规模,充分利用外汇储蓄,设法解决股权分置问题。     

中国证券市场"市值效应"的实证研究

“市值效应”是一个长期存在于各国证券市场的特殊现象。通常认为，市场上市值总额小的公司股票平均收益率要明显大于市值总额大的公司股票平均收益率。通过对中国证券市场的市值效应进行实证研究发现，在近三年，无论市场处于牛市或熊市，大市值风格组合始终具有较好的业绩；而“小市值效应”仅出现在牛市。     

The economics of the Swedish online gambling market

In this article, we study how the Swedish online gambling market has developed and how the availability of foreign-based online gambling has affected the domestic state-owned gambling monopoly, AB Svenska Spel. We find that online gambling and the traditional state-managed gambling are relatively weak substitutes. Thus, concerns about the availability of online gambling being able to undercut domestic gambling policies may be overstated.     

The extent of the market and optimal specialization

Summary. In this paper I examine how the socially optimal allocation, and specialization in particular, depends on the extent of the market. I interpret the societys ability to keep transaction records as the extent of the market and measure it by a probability with which the society can update agents past transactions into the public record. The society uses this record to detect potential defections from the optimal allocation and to punish the defectors with autarky. I show that when is small, increasing increases optimal specialization. However, when is close to 1, increasing further has no effect on the optimal allocation. I also show that optimal specialization is gradual over time when there is cost to reduce specialization. Even for small , the process converges to the unconstrained optimum that would occur under .JEL Classification Numbers: D60, C78.An earlier version of this paper was presented at the Society for Economic Dynamics meetings in Stockholm (2001).

The electricity market game

This paper examines the effects of imperfect competition in unregulated electricity markets from a general equilibrium perspective, and demonstrates that horizontal market power can explain both the large peak-period price spikes observed recently in California and elsewhere, and the marked reduction in addition to capacity that have also occurred during the transition to competitive markets.     

The stock market and the vacancy rate

This paper analyzes the vacancy rate in competivive markets. It is shown that the competitive vacancy rate is suboptimal and that it can be higher or lower than the optimal rate.     

The market for preferences

Learning processes are widely held to be the mechanism by whichboundedly rational agents adapt to environmental changes. Weargue that this same outcome might also be achieved by a differentmechanism, namely specialisation and the division of knowledge,which we here extend to the consumer side of the economy. Wedistinguish between high-level preferences and low-level preferencesas nested systems of rules used to solve particular choice problems.We argue that agents, while sovereign in high-level preferences,may often find it expedient to acquire, in a pseudo-market,the low-level preferences in order to make good choices whenpurchasing complex commodities about which they have littleor no experience. A market for preferences arises when environmentalcomplexity overwhelms learning possibilities and leads agentsto make use of other people's specialised knowledge and decisionrules.     

The division of labor and the extent of the market

Summary. A firms degree of specialization is modeled as the number of different goods it produces. When a firm chooses its degree of specialization, it faces a tradeoff between the fixed cost and the marginal cost of production. A firms degree of specialization is shown to increase with the extent of the market. Meanwhile, the real wage rate, as a measure of the extent of the market, is endogenously determined in the model and is shown to increase with the division of labor.Received: 29 April 2002, Revised: 18 June 2003, JEL Classification Numbers: A10.The author thanks an anonymous referee and Antonio Ciccone for their very valuable and constructive suggestions.

The effects of competitors on new product launch and market expansion in the hybrid car market

This paper evaluates the effect of competitors on automakers’ new product launch and market expansion decisions in the hybrid car market. Using data from the entire history in US hybrid car market from 2000 to 2014, this paper estimates a Poisson model with endogeneous switching to account for the initial launch and the following expansion decisions. The results indicate that the presence of competing brands’ hybrid vehicle models has a net positive effect on a brand’s initial launch and expansion decisions. This suggests that demand expansion and market learning from competitors’ hybrid model launch and consumer cultivation are very important for this relatively new technology. Further, I find that the impact of competitors varies over time, vehicle origins, and classes.     

The market for protection and the origin of the state

We examine a stark setting in which security or protection can be provided by self-governing groups or by for-profit entrepreneurs (kings, kleptocrats, or mafia dons). Although self-governance is best for the population, it faces problems of long-term viability. Typically, in providing security, the equilibrium market structure involves competing lords, a condition that leads to a tragedy of coercion: all the savings from the provision of collective protection are dissipated and welfare can be as low as, or even lower than, in the absence of the state. Thus, we explain the tendency towards autocracy both in history, before the appearance of modern representative governance, and in many low-income countries in modern times.     

The external cost of asbestos in the housing market

This study uses a Generalized Method of Moments spatial error hedonic model to estimate the potential impact of asbestos on residential property prices. The analysis examines a large sample of 32,403 housing sales occurring between 2008 and 2015 in a fast-growing Coastal Alabama region. Results indicate the presence of asbestos depreciates house values by 13.44%, translating into an external cost of approximately $25,300 per property.
