Option Pricing in ARCH-type Models

ARCH models have become popular for modeling financial time series. They seem, at first, however, to be incompatible with the option pricing approach of Black, Scholes, Merton et al., because they are discrete-time models and possess too much variability. We show that completeness of the market holds for a broad class of ARCH-type models defined in a suitable continuous-time fashion. As an example we focus on the GARCH(1,1)-M model and obtain, through our method, the same pricing formula as Duan, who applied equilibrium-type arguments.     

Public policies,pressure groups,and dead weight costs

This paper presents a model of competition among special interest groups for political influence. Each active group exerts pressure to affect its taxes and subsidies, where activities of different groups are related by the equality between total tax collections and total tax subsidies. The dead weight costs and benefits of taxes and subsidies play a major role in our model. An increase in the dead weight cost of taxation encourages pressure by taxpayers, while an increase in the dead weight costs of subsidies discourages pressure by recipients. Various applications of the analysis are discussed.     

The Politicisation of Banking

Growing government intervention in the international currency markets has distorted incentives and disguised risks. Rodney Atkinson, formerly an economist with Grindlay's Bank, argues that increasing state interference has led bankers to respond to political, not commercial, signals. Many bankers are now rewarded according to their ability to 'work the system' rather than for economic expertise.     

THE PRESIDENT'S COMMISSION ON PENSION POLICY HOUSEHOLD SURVEY 1979: NET WEALTH DISTRIBUTIONS BY TYPE AND AGE FOR THE UNITED STATES

A household survey was done for the U.S. President's Commission on Pension Policy (1979-81). This paper reports on the net wealth of families in the United States for the year 1979, the first wave of the survey. The survey was begun in September 1979 and was a two-wave, nationwide random sample of households in the United States. The survey instrument gathered information on income, wealth, labor supply, participation in pension plans, vesting status, entitlement to various benefits, attitudinal views on retirement, social security wealth, and individual demographic characteristics. Details of the survey methodology are reported. A response rate of sixty-two percent was achieved among the 6,384 dwelling units in the first wave. Imputations are made to calculate the wealth embodied in private and public employee-based pensions. Included in this valuation is an adjustment for expected vesting status in the pension plan. Net wealth is examined by type and age of the head of household. The average net wealth of the family is $53,956, and the average value of retirement wealth is $3,281 which comprises about 5 to 6 percent of net wealth. The striking changes in the portfolio of net wealth are depicted over the cross-section of age cohorts. The oldest age cohort, 65 and over, is found to have for retirement wealth the lowest frequency of ownership, the lowest proportion of their portfolio in this form of wealth, and the second to lowest average value.     

Inflation,Translation and Conflicts in Statements of Financial Accounting Standards*

This paper utilizes the concept of aggregative consistency defined in Rubinstein and Fishburn [1986], and the FASB's concept of representational faithfulness to evaluate foreign currency translation and accounting for changing prices as embodied in SFAS 70. The paper shows that SFAS 70 produces measurement errors and creates a foreign currency translation adjustment which does not reflect the effects of exchange rate changes. The conditions defined in the paper also facilitate an evaluation of the relative merits of restate/translate and translate/restate. Restate/translate can conceivably be used if there is no consolidation. In the more usual case where consolidation is required, translate/restate using the relevant shareholders' consumption index will yield aggregatively consistent values under fewer restrictive conditions.     

IS A THEORY OF TOTAL FACTOR PRODUCTIVITY REALLY NEEDED?

This paper addresses the question of whether or not a theory of total factor productivity (TFP) is needed in order to explain the observed large per capita income differences across countries. As the argument that it is needed has been reached by calculating TFP empirically, we show that the way the estimates of TFP have been computed is not an innocuous issue. To illustrate our point, we discuss how two well‐known textbooks on growth theory present the arguments and the problems associated with these expositions. We conclude that the tautological nature of the estimates of TFP lies at the heart of an important question that the empirical literature on economic growth has been dealing with during recent years. Hence, our arguments cast doubt on the need for a theory of TFP.     

The integration of the formal and informal urban sectors in South Africa

Although the centre down and grass roots approaches in many respects may represent a developmental antithesis, a good case may be made for the combination of the two approaches under dualistic economic circumstances. An attempt is made in this paper to demonstrate how these diverse development policies may be successfully reconciled in urban Southern Africa. A review is given of the theoretical foundation of the two development approaches with a view to indicating how some aspects of these approaches may be combined to integrate the formal and informal sectors in urban areas in Southern Africa.     

The Road is Long: Thirty Years of Equality Legislation in Britain

This article critically reflects upon the development of British employment equality law, tracking a positive yet hesitant, uneven and incomplete trajectory from anti‐discrimination towards equality, and from piecemeal and patchwork coverage towards inclusiveness, integration and intersectionality. It argues that the opportunities provided by the new Commission for Equality and Human Rights and the proposed Single Equality Act should be taken to address remaining weaknesses in the legislative equality package and the limitations in enforcement approaches which the article highlights.
