中国资产价格膨胀与日本泡沫经济的比较与启示 总被引:6,自引:3,他引:3
近年来,中国资产价格上涨已经引起了国内外广泛关注,这与日本泡沫经济前期的情况如出一辙。_良好的经济基本面、宽松的资金面和市场信心是推动中日两国资产价格上涨的共同因素。而中日两国长期实行出口导向型经济发展战略,依靠间接融资的金融体制,成为导致两国资产价格膨胀的深层次原因。与日本相比,中国资产价格膨胀可以在较大程度上化解,不会重蹈日本资产泡沫破灭的覆辙。但短时间内资产价格过快上涨,成为经济增长和金融稳定的潜在风险,为此,中国应该积极总结日本泡沫经济时期的经验教训,从日本政府的应对政策中得出重要的启示。 相似文献

Why do farmers have so little interest in futures markets? 总被引:1,自引:1,他引:0
Phil Simmons 《Agricultural Economics》2002,27(1):1-6
A farm financial model with leverage and investment in two farm enterprises is specified. The model is extended to incorporate futures hedging and the Separation Theorem is used to show that optimal hedging is zero. The assumption of a risk‐free asset is relaxed and, while this leads to a violation of the Separation Theorem, the result that optimal hedging is zero is maintained providing that futures markets are efficient. It is concluded that if capital markets are efficient then farmers will have little interest in futures markets except to speculate. 相似文献

The theory of demand and supply implies a positive relationship, or “price transmission” between the prices of products at different stages of manufacturing. This relationship was investigated with quarterly prices of softwood stumpage in the US South, and national prices of forest products, from 1977 to 2002. All prices, net of inflation, were found to be nonstationary and there was no evidence of co-integration between prices. Vector autogressive models, augmented by Granger causality tests and multiplier analysis showed that there was a one-to-one permanent positive response of the southern sawtimber stumpage price to a permanent change in the national lumber price. There was also a one-third permanent positive response of the national paper price to a permanent change in the national pulp price. There was no relation between regional pulpwood prices and national pulp or paper prices. When price transmission was significant, the full adjustment took about 2 years. 相似文献

基于EGRACH模型的股指期货对股市非对称性波动影响的实证研究 总被引:1,自引:0,他引:1
本文基于EGRACH模型,利用高频数据,实证检验了沪深300股指期货对我国股市非对称波动的影响。实证研究表明,沪深300股指期货与现货市场之间存在互为格兰杰因果关系,在股指期货初期股指期货对股市的波动有放大作用,在远期降低了非对称性波动,具有稳定股市的功效。 相似文献

In this paper, I show that nineteenth century US interest rates are relatively more volatile before 1874 and I propose, and demonstrate how, commodity futures trading is the likely principal proximate explanation for this change in behavior. Borrowing from Turnovsky [Econometrica 51 (1983) 1363], I model the optimizing behaviors of risk averse producers and risk neutral speculators in the absence and presence of futures contracts and I show that, so long as one party to a futures contract was risk averse, futures markets would have quelled interest rate volatility caused by variations in planting and harvesting conditions. 相似文献

This paper investigates the hedging effectiveness of Australian, Hong Kong, and Japanese stock futures markets. The traditional hedge and the minimum variance hedge ratios are all constant whereas the bivariate GARCH hedge ratio is time varying. The effectiveness of the hedge ratio is compared by investigating the out-of-sample performance of the three ratios. The whole sample consists of weekly returns from January 1990 to December 2000. Two 1-year, out-of-sample periods are used: January 1999 to December 1999 and January 2000 to December 2000. Results show that the time-varying GARCH hedge ratio outperforms the constant ratios in most of the cases. This is true using both out-of-sample periods. 相似文献

Trade mechanism selection in markets with frictions 总被引:1,自引:0,他引:1
We endogenize the trade mechanism in a search economy with many homogeneous sellers and many heterogeneous buyers of unobservable type. We study how heterogeneity and the traders' continuation values—which are endogenous—influence the sellers' choice of trade mechanism. Sellers trade off the probability of an immediate sale against the surplus expected from it, choosing whether to trade with everyone and how quickly. In equilibrium sellers may simply target one buyer type via non-negotiable offers (price posting), or may price discriminate (haggling). We also study when haggling generates trading delays. A price setting externality arises because of a strategic complementarity in the sellers' pricing choices. 相似文献
