The lack of sufficient market depth particularly in many newly initiated futures markets results in relatively high hedging costs, and this inhibits the growth of futures contract volume. In this article the price path due to order imbalances is analyzed and a two-dimensional market depth measure is derived.Understanding the underlying structure of futures market depth provides the management of the futures exchange with a framework for improving their market depth and gives hedgers a better understanding of market depth risk. The managerial implications of our findings are demonstrated empirically using data from the Amsterdam Agricultural Futures Exchange.  相似文献

我国三线城市保险业发展存在着严重的不平衡,而且差距较大;影响三线城市保险业发展的因素众多。主要包括GDP、人口数量及分布、城镇居民人均可支配收入和地理位置等。经济发达的省份,三线城市保险业发展水平也普遍较高;但在整体保险业发展水平落后于东部发达地区的情况下,部分中西部三线城市的保险业发展水平却并不低,而且有的已超过了一些省会城市,三线城市所蕴含的商机逐步显现。  相似文献

When future human capital cannot be alienated, households are allowed to borrow up to the point where it is in their own interest not to default. In such a framework, endogenous borrowing limits arise as the outcome of individual rationality constraint. In a model where education is the engine of growth, we show that endogenous borrowing constraints imply global indeterminacy. Comparing outcomes across the various equilibria we show that the relation between growth and yields is hump-shaped. Maximum growth can arise in an equilibrium with binding borrowing constraints, specially if the elasticity of human capital to education spending is large. Deepening financial markets promotes long-run growth in the case of a poverty trap, but not necessarily otherwise. On the methodological side, our approach stresses the importance of studying borrowing limits in general equilibrium, not only in small open economies. Philippe Michel passed away on July 22, 2004. His death is a great loss for his friends and for the overlapping generations and optimal control community.  相似文献

In a study of 1,131 stock splits spanning the period 1983–1989 we observe an increase in the number of trades as well as a reduction in the mean trade size following the split. Combined with earlier reported findings of an increase in the number of shareholders postsplit, we conclude that the number of liquidity traders increases after a split. We confirm the previously observed increase in the bid-ask spread following a split, and upon decomposition of the spread find an increase in its adverse selection component in the postsplit period. This is consistent with the finding by Brennan and Hughes (1991) of an increase in the number of analysts following a stock after a split. Further, observing a decrease in market depth following a split we determine that Kyle-type models incorporating diverse private information for informed traders most correctly describe the nature of security trading. Since this decrease in postsplit market depth is not related to the trading volume or the split factor, we reject price correction explanations for stock splits.  相似文献

This paper examines price clustering on the Tokyo Stock Exchange (TSE). Regardless of tick and lot size, prices ending in zero and five are the most popular. The TSE has no market makers or direct negotiation between traders; therefore, clustering is not explained by collusion or negotiation. Our evidence supports the attraction hypothesis. Clustering also extends to order book depth. There is evidence of strategic trading behavior as traders place orders one price tick better than zero and five to avoid queuing orders at prices ending in these digits. Strategic trading behavior declined and clustering increased when the market became anonymous.  相似文献

Abstract:  We consider the impact of the May 1999 move to screen trading of the LIFFE FTSE 100 index futures contract. This resulted in a narrowing of the effective spread. Spread determinants are broadly similar in the two regimes. The narrowing of the spread appears due to increased competition among traders and a decline in tick-level volatility rather than to the way these or other variables affect the spread. Market depth appears largely unaffected. Under screen trading, realized spreads widen as more limit orders are taken up rather than in relation to order size per se .  相似文献

In the present study we conduct constant market share analysis of the imports and apparent consumption of the manufacturing industries of four major economies‐Korea, Japan, Taiwan and the USA. Additionally, the current study disaggregates import penetration in manufacturing, including sectors with relatively high technological requirements. Statistical tests of the significance of changes in import penetration in manufacturing industries are also conducted. The real growth of exports and apparent consumption in the two largest OECD markets is decomposed into: (i) the commodity composition effect; and (ii) the competitiveness effect. Finally, we examine the significance of trade policy for changes in import penetration in Japan and the USA.  相似文献
