建立商品期货持仓风险指数的设想

期货投资是一种风险度很高的金融投资方式,由于中国在很多大宗商品上尚未取得定价话语权,因此中国期货市场的价格波动受外盘的影响很大。对于持仓过夜的投资者而言,一旦持仓方向错误,就会遭受巨大的经济损失。有鉴于此,提出了建立适合中国国情的定量化商品期货持仓风险指数的设想,以帮助投资者认清各品种持仓过夜的市场风险,做到理性投资。     

Deliveries on Commodity Futures Contracts

Deliveries on futures contracts are widely thought to be relatively insignificant in amount; indeed sizeable deliveries are taken to indicate problems in a futures market. In fact, deliveries on five of the largest, physical delivery, futures markets in the US average approximately 10 per cent of the maximum open interest in each delivery month. Analysis also demonstrated the value of the timing and location options often provided by contract specifications. One implication is that measures of market performance like hedging effectiveness are sensitive to the imbedded options' effects on prices     

Futures markets,private storage,and price stabilization

This paper considers several issues pertaining to the role of an efficient futures market for price stabilization. The main aspect which is emphasized is the provision of information by such a market. It provides efficient forecasts which facilitates both production and storage decisions, as a result of which the stability of spot prices is generally increased. The allocation of the benefits from a futures market to the various groups in the economy is discussed andthe present results related to those of the more traditional buffer stock literature. Finally, the degree of stability provided by a futures market is compared with that obtained by active market intervention by a stabilization authority.

Simultaneity,Forecasting and Profits in London Copper Futures

Previous research on price determination for non‐ferrous metals at the London Metal Exchange (LME) suffers from three limitations: first it has employed single equation methods only, which cannot explain the simultaneous determination of spot and futures prices; second, by focusing on current and lagged prices, previous research does not analyse the effect on price determination of critical variables such as expectations, consumption and inventories; third, the outcome of prior research regarding market efficiency is ambiguous. This paper, which addresses these issues, develops a simultaneous model of the copper market at the LME, with representation of the activities of hedgers, speculators and consumers. This model produces post‐sample forecasts of the spot price which outperform conventional benchmarks, thus providing evidence against the efficient market hypothesis. Model‐derived forecasts are employed as the foundation of a trading program which produces risk‐adjusted profits (net of commission costs) for holding periods of one week and one month, thus fulfilling the ‘sufficient condition’ for market inefficiency. This study, therefore, provides new insights into price determination on the LME copper market, and resolves the ambiguity of previous research regarding the efficiency of that market. This is the first application of the model forecasting approach to the question of performance of the market for copper.     

动力煤期货和焦炭期货套期保值的比较分析--基于最小方差的 Copula 模型

伴随着经济结构转型和资源结构调整,煤炭市场遭遇寒冬,煤炭期货套期保值也备受关注。在对两种主要煤炭期货———动力煤期货和焦炭期货的基本套期保值现状进行对比的基础上,利用GARCH模型对两种期货收益率方差进行预测,同时利用EWMA模型对其现货收益率方差进行预测,最后利用最小方差的Copula模型对两者的套期保值比率进行确定,并对比性评价了两者的套期保值效率,以此为处于困境中的煤炭企业提供方向指导和建议。     

基于仿真交易的股指期货定价效果研究

本文通过研究我国仿真股指期货和沪深300指数之间的关系,发现仿真股指期货价格与现货价格在一定滞后阶数上构成单向的Granger因果关系:期货价格在统计意义上是现货价格的Granger原因,反之并不成立.另一方面,尽管现货与期货价格之间的基差不稳定,但通过计算现货与期货收益率基差发现其存在稳定的关系,而且收益率基差的异常值有助于预测未来沪深300指数和股指期货的相对趋势.     

Futures We Are In

The economics literature includes several critiques of the dominant utilitarian position, as respectively offered by Posner (1979), Rawls (1971), Sen (1987) and institutionalist followers of John Dewey. There is also now a rapidly growing literature on the economics of happiness. Another quite distinctive position of social importance on these issues is provided by Joseph Ratzinger, also known as Pope Benedict XVI. It offers an alternative conception of ontology and teleology, and reflects conceptions of freedom, happiness, man and rationality different from those found in orthodox economics, and different too from those found in the above-mentioned critiques. It intersects with recent writings of Lawson (2003), Nelson (2010) and Tilman (2008).

In order to promote critical scrutiny of the a priori positions embedded in contending schools of economic thought, it follows that the implications of this Ratzinger critique should be consciously confronted by economists, including institutionalists, with whom various starting points are shared.

Futures markets,price stabilization and efficient exploitation of exhaustible resources

Markets for natural resource futures contracts and cash forward contracts experience a rapid growth. According to theory, this should result in more efficient resource depletion, implying that price formation is more consistent with Hotelling's rule. The rationale of this stabilization effect is briefly discussed. Next, we analyze the impact of expanding futures markets on the behaviour of individual resource owners trading on the cash market. Using a simple pulse extraction model, we demonstrate that the expected time of depletion can shift to the present or the future, and that utility of exploitation can go up or down, as market prices are stabilized.     

基于非合作博弈的期货市场策略分析

本文基于非合作博弈的方法,通过建立非合作博弈模型对期货市场多空双方的行动策略进行分析,分别就完全信息博弈、不完全信息博弈和不完美信息博弈三种不同的博弈环境,讨论了多空双方在不同的市场形势下的行动策略、博弈的均衡及结果。分析结果表明在不同的博弈环境下,无论是均势市场、多头市场还是空头市场,资金和信息对于期货市场多空双方的博弈策略具有至关重要的影响。基于此结论,本文进一步提出,为了获得资金优势和信息优势,建立期货投资基金,形成博弈联盟是一种有效的博弈形式,以此为基础的合作博弈分析方法是分析联盟博弈的有效方法。
