This paper develops a model of the relationship between investment decisions by firms and the efficiency of the market prices of their securities. It is shown that more efficient security prices can lead to more efficient investment decisions. This provides firms with the incentive to increase price efficiency by voluntarily disclosing information about the firm. Disclosure decisions are studied. It is shown that firms may expend more resources on disclosure than is socially optimal. This is in contrast to the concern implicit in mandatory disclosure rules that firms will expend too few resources on disclosure. 相似文献

Teece (1982) extended Coase's (1937) theory of the firm to explain firm amalgamations. This explanation is centred around three fundamental constructs: excess capacity, market imperfections and the nature of assets, together with the frequency of their exchange. This paper provides an application of Teece's work to explain recent organizational change within the stockbroking industry in Australia and concludes by developing testable explanations of why, following deregulation, stockbroking firms countenanced moves by financial institutions, particularly banks, to acquire large equity positions. 相似文献

A number of recent US. studies have examined the price impact of large (block) trades using intraday data. A major finding is that the price movement following block trades continues upwards following purchases but reverses following sales. This asymmetry in price behaviour, which suggests that block sellers pay a liquidity premium while block buyers do not, has been described as 'intriguing' and a 'key puzzle'. The purpose of this note is to determine whether the phenomenon exists on the Australian Stock Exchange. Evidence consistent with the 'puzzling' asymmetry is shown to exist when returns are measured from the block trade until the close of trade. Contrary to US. findings, which have shown that prices appear to reverse following both block purchases and sales in transaction time analysis, the asymmetry in price behaviour is also demonstrated to exist in transaction returns for the ASX. All results are found to be robust to a number of research design innovations and data partitions. 相似文献

This paper offers new evidence that inter-industry inequality has increased since the early seventies. An examination of de industrialization, segmented labor market, and international competition explanations of this increase shows that the growth of inequality is accounted for mainly by growing wage differentials among industries, notably between primacy and secondary sectors. Employment shifts out of middle-wage industries and employment and wage effects of international trade do not explain the inequality increase. 相似文献
