Value Cores for Finite Agents*

The standard definition of the competitive equilibrium, at given prices, presents the difficulty that finite agents (i.e. agents with finite budget and production sets), and a fortiori coalitions of such agents, need not be price takers and will upset the equilibrium. Since 1963 an extensive literature has sprung up, which has dealt with the problem, essentially by considering infinite numbers of infinitesimal agents. The present article outlines two alternative approaches to deal with this problem, both of which, realistically, admit (a finite number of) finite agents and redefine the core in terms of the value structure of the economy, viz. prices in the presence of controls, and cost and revenue functions in their absence. It is shown that the notion of value core, here introduced, coincides with that of competitive equilibrium, which is formulated as a characteristic-function game.     

The Dynamics of Incomes and Occupational Pensions after Retirement

This paper uses two waves of the UK Retirement Survey to look at how incomes change during retirement. We concentrate on men aged 65–69 and women aged 60–69 in 1988–89 and look at how their incomes change over the following five years. Overall, we find a considerable degree of stability in real incomes. We use the panel data to look at the incomes of widows before and after they are widowed and find that, for this group of relatively young widows, their low incomes are in large part determined by the fact that it tends to be the relatively poorer husbands who die among this age-group. Finally, we consider the most important component of private income — occupational pensions — separately. We find a strong relationship between pension level and the probability of indexation — pensions that start low are less likely than higher pensions to keep up with inflation.

Measuring the national wealth in seventeenth-century England

This article discusses William Petty's 1665 estimate of the wealth of England and Wales—the first set of national accounts—and compares it with Gregory King's (1696), which is shown to be heavily influenced by it. There are conclusions about the methodology of the first political arithmeticians, the kinds of national resources which could be measured for the first time in the seventeenth century, and the lacunae which made it likely that Petty and King underestimated per caput and aggregate incomes. An appendix prints a contemporary analysis of hearth tax returns for every county.     

Financial Covenants in Australian Bank-Loan Contracts: Incidence, Measurement Rules and Monitoring

This paper reports the results of an interview survey of 48 Australian bank lending officers on the use of financial covenants in bank-loan contracts. A wide variety of financial covenants appear to be used. As expected, the accounting measurement rules were generally conservative in nature but they appeared to be less restrictive in other areas. The results were compared with similar studies of Australian public-debt contracts and US and UK bank-loan contracts and considerable cross-market diversity was noted. Evidence on the frequency and method of monitoring these covenants is also documented.     

Briefing Paper

Between the end of 1979 and the end of 1981 unemployment rose by 1.4 million. After that exceptional period unemployment continued to rise rather less rapidly to its current level of 3.2 million, Of this 3.2 million, about 1.3 million have been unemployed for more than a year. In this Briefing Paper we describe and attempt to explain the processes by which long-term unemployment rose to its current level.
We also discuss two related questions; the first concerns the relationship between unemployment and vacancies and the second concerns the relationship between long-term unemployment and inflation. The final sections consider the policy implications of these findings.     

Storage changes in biscuits

The purpose of this research was to investigate the changes occurring in biscuits under domestic storage conditions. The experimental work involved the storage of manufactured biscuits under closed, open/light and open/dark conditions for appropriate periods of time. Moisture content, texture, colour and peroxide value were determined throughout the storage time. The results indicate that the moisture content of the samples increased under all storage conditions, with a softening of texture. Peroxide values increase with rapid acceleration towards the end of the storage period. Very little change was observed in the colour of the biscuits.
