Further Evidence on Foreign Exchange Market Efficiency: An Application of Cointegration Tests

This study extends and expands the body of evidence related to foreign exchange market efficiency by employing the single-equation cointegration test proposed by Phillips and Ouliaris [19], and the Johansen [12] 1991 Full Information Maximum Likelihood procedure for a system of equations. Through the use of these updated techniques and a global data set, the authors are able to more carefully test for the presence of cointegrating relationships and examine the consistency of the results in three trading locations. The results are quite consistent across locations and are highly supportive of efficiency in the global foreign exchange market.     

Trust-Based Relationships in Local Government Contracting

This article examines issues of trust and competition as they relate to a number of services provided by British local government. The first section outlines the changing policy context of competition for local authority services and is followed by a discussion of the nature of trust under contracting, drawing on elements of (primarily) economic theory to identify the features of contracting which we would expect to find in a 'low trust world'. The authors ask whether these features appear to be present in contracting and point to some features of the CCT legislative framework which may help to explain this. After reviewing private sector practice, the extent to which it could be replicated under CCT is examined.

State promotion of high-definition television

Governments have used a number of mechanisms to support research and production in domestic industries that are considered strategic. In recent years the Japanese system of administrative guidance and support for pre-competitive research joint ventures has arguabh proved the most successul High-dgfnition teleuislon ( H D V provides an interesting new case study in government support for high-tech industries. Wzile the failure of the EC's venture in this jeld is perhaps unsurprising, the MUSE pryect in Japan has suffered a similar fate. Success in HDTV har been achieved by the US government's novel use ofpre-competitive contests in which domestic and overseas companies are free to form consortia and to arrange side-payments which share out the winning 'prize'. This innovation in the state's promotion of innovation may haue wider applications, though its repeated use could inhibit research by individual companies able tojee-ride on the contest winners.     

A stochastic control approach to buffer stock management in the Taiwan rice market

Buffer stock management of agricultural commodities is an intertemporal optimization problem under uncertainty. Stochastic optimal control techniques are presented as a means of solving this problem and then applied to the problem of farmer income support and price stabilization of the rice market in Taiwan. Deterministic results show that the price variation of a free market solution can be substantially reduced with little favoring of one group over another. Operation of a buffer stock under supply uncertainty is shown to generate greater variability in consumer expenditures and producer income than a free market solution.     

ON THE CORRESPONDENCE BETWEEN THE BAUMOL-TOBIN AND MILLER-ORR OPTIMAL CASH BALANCE MODELS

In this note, the author identifies a correspondence relationship between the Baumol-Tobin (BT) and Miller-Orr (MO) optimal cash balance frameworks and specifies the conditions under which both models imply the same level of optimal cash balances. Realistic applications of these models will concern net cash flows that exhibit behavior somewhere between the two extremes of BT entirely deterministic and MO completely random. The author demonstrates that if the correspondence relationship is satisfied, either the BT or the MO cash balance model can be employed since both models imply the same result. One conjecture open for empirical verification is that cash balance models perform more (less) adequately for groups of firms that satisfy (violate) the correspondence relationship.     

CAPITAL RECONSTRUCTIONS: ARE THEY REALLY NECESSARY?

The topic of capital reconstructions is covered in most texts on company accounting and included in most company accounting courses of study at tertiary institutions. Unfortunately, though, there exists little material on the extent of the application of the available reconstruction options, and the usefulness of these options to companies and shareholders. This paper outlines the extent and type of the capital reconstruction schemes proposed by Australian listed companies between 1975 and 1977. Some research regarding the effectiveness of two of the options is then outlined. Finally, a call is made for research to be undertaken into the other available options to determine whether their implementation is really warranted.
