MACROECONOMIC FACTORS, THE APT AND THE UK STOCKMARKET

This paper examines the macroeconomic sources of risk priced in the UK stockmarket between 1983 and 1990 using monthly data on 840 stocks to form both beta-sorted and market value sorted portfolios using the methodology proposed by Chen, Roll and Ross (1986) and Chan, Chen and Hsieh (1985) for the US. We find that several intuitively plausible macroeconomic variables were priced over this period using the beta sorted portfolios and that once these variables are included there is little role for the return on the market. However, when the market value sorted portfolios were used only inflation and a measure of equity market 'expense' relative to gilts was priced; furthermore with the market value sorted portfolios a role for the market return was found.     

银行信息化和银行管理之间的若干关系探讨

长期以来,由于对银行信息化与银行管理之间的关系缺乏深入研究,在信息化过程中过分地依赖于技术手段,使得信息化成功率偏低.本文认为,银行信息化与银行管理存在着双向互动关系:一方面,银行信息化改变了银行管理的基本模式;另一方面,银行管理实践又对银行信息系统及其信息技术的应用范围和行为规则产生了约束.判断银行信息化成功与否的标准,并不是看采用了多少先进的技术或软硬件设备,而应在分析银行经营战略的基础上,选择恰当的信息技术组合,使银行信息化既能够与当前组织结构相协调,又能有效解决银行普遍存在的激励失效问题,并被用户所接受,从而使银行的劳动生产率得到提高.     

CHANGES IN THE STOCK PRICE REACTION OF SMALL FIRMS TO COMMON INFORMATION

We hypothesize that changes in the technological and regulatory environment result in a more rapid response to marketwide information by small firms. We find that the correlations between small-firm returns and lagged large-firm returns decline over time, which suggests an increase in the efficiency of capital markets. Similar lead-lag patterns are found in the returns of portfolios sorted by dollar trading volume. The price response of low-volume stocks improves over time in much the same way as that of small-capitalization stocks.     

FURTHER EVIDENCE ON EMPIRICAL RELATIONSHIPS BETWEEN EARNINGS AND CASH FLOWS

Recently in Australia, regulations have been proclaimed requiring companies to make cashflow disclosures in addition to earnings disclosures from 30 June 1992. This paper provides evidence on relationships between earnings and cash flow measures and in so doing examines the external validity of a U.S.A. study of these relationships by Bowen, Burgstahler and Daley [1986]. We also extend their study through an industry analysis of the relationships. Evidence is presented first that shows low correlations between traditional cash flow measures (i.e., net income plus depreciation and amortisation; and working capital from operations) and a more refined cash flow measure (with additional adjustments for changes in non-cash current assets and current liabilities). Second, traditional cash flow measures exhibit high correlations with earnings, while the more refined cash flow measure has a lower correlation with earnings. Finally, traditional cash flow measures better predict future cash flows than models based on earnings or a more refined cash flow measure. The industry evidence, albeit on small sample sizes, shows that the results on the first two issues, but not the latter issue, are generalisable across industry categories.     

TRADING PATTERNS OF SMALL AND LARGE TRADERS AROUND STOCK SPLIT EX-DATES

We investigate the trading patterns of small and large traders around stock split ex-dates. Using the intraday transaction database for the Toronto Stock Exchange during 1983–89, we find that stock splits are associated with significant changes in trading patterns. Although stock splits appear to have little effect on the trading behavior of large traders (trade value of at least $100,000), they are associated with significant decreases in odd-lot trading and increases in small board-lot trading (trade value of less than $10,000). Although the liquidity premia decrease for all trade sizes, trade direction changes significantly from sell to buy after split ex-dates for all but the large trades, where the change is in the opposite direction. The significant increase in variances after split ex-dates is explained by various microstructure-related variables, and small (large) trades appear to be (de)stabilizing.     

DYNAMIC RELATIONS BETWEEN MACROECONOMIC VARIABLES AND THE JAPANESE STOCK MARKET: AN APPLICATION OF A VECTOR ERROR CORRECTION MODEL

By employing the vector error correction model (VECM) in a system of seven equations, we find that the Japanese stock market is cointegrated with a group of six macroeconomic variables. The signs of the long-term elasticity coefficients of the macroeconomic variables on stock prices generally support the hypothesized equilibrium relations. Our findings are robust to different combinations of macroeconomic variables in six-dimension systems and two subperiods. Also, the VECM consistently outperforms the vector autoregressive model in forecasting ability.
