Disclosure Decisions by Firms and the Competition for Price Efficiency

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.     

Organizational Change within the Stockbroking Industry: A Contracting Perspective

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.     

Asymmetry in Stock Returns Following Block Trades on the Australian Stock Exchange: A Note

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.     

Income Inequality: An Inter-Industry Analysis

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.     

Economic Viewpoint

The search for a policy device which will yield the benefits of monetary discipline without the pain is as old as it is fruitless, and the central message of this Economic Viewpoint is that going into the EMS will not provide a magic answer to our problems. However we believe that if we go into the EMS at today's rate, and pursue monetary policies consistent with maintaining that rate, the authorities' target of 3 per cent inflation by 1988 is well within reach… Our analysis of the experience of other countries, inside and outside the EMS, over the floating rate period suggests that membership of the EMS should also reduce exchange rate fluctuations and help to create a more stable environment for business planning. However, sterling's vulnerability to oil-related fluctuations cannot be eliminated just by joining the EMS. We therefore suggest that an oil bond, which capitalises the value of our North Sea assets, is created and sold to our EMS partners, thus equalising the exposure to fluctuations in oil prices and removing one major cause of exchange rate instability.     

Capital Asset Pricing Compatible with Observed Market Value Weights

We show that the set of expected return vectors, for which an observed portfolio is mean variance (MV) efficient, is a two-parameter family. We identify ten ways to specify the time series behavior of the two parameters; the result highlights a number of inconsistencies involved in MV modelling. For each of the cases, it permits the inference of the time series of expected return vectors, as well as all the other Capital Asset Pricing Model (CAPM) variables, compatible with a known covariance matrix and the observed time series of market value weights. The empirical work shows that there are substantial case-to-case differences in the time series of mean vectors and many of them are quite different from the constant mean vector envisioned in tests of the CAPM.
