The article presents abstracts of articles related to general economics. The articles include Why We Need Economic Growth by W. Beckerman. The author holds that value judgements on growth need clarification, to which the economist can contribute his specialist knowledge. The presence of external costs is often taken to imply a conflict with welfare but, even if external costs per unit of output rise with greater output, economic welfare need not decline. The article Convexity and Continuity Properties of Preference Functions by R.R. Cornwall, studies the convexity properties of the preferences of a perfectly competitive economy. This discussion is related to the problem of establishing conditions for the equivalence of two kinds of blocking used in the definition of the core of an economy. The article Recursive Decision Systems: An Existence Analysis by R.H. Day and P.O. Kennedy explains the concept of recursive decision systems which are models of socio-economic processes. The article Some Basic Problems on Excess Demand Functions examines carefully the basic problems of excess demand functions.

This section presents abstracts of research and articles on statistical methods used in economics, econometrics and social accounting. In their article, A Note on the Dual Prices of Integer Programs, R. E. Alcaly and A. K. Klevorick propose an alternative view of integer programming problems by presenting a recomputation process that enables a reconciliation of the integer and linear programming properties. A. R. Bergstrom's article, Nonrecursive Models as Discrete Approximations to Systems of Stochastic Differential Equations, is concerned with the specification error implied by the use of a nonrecursive model as a discrete approximation to a system of stochastic differential equations. In the paper, Financial Accounting: Its Present State and Prospects, author G. S. Dorrance reviews the presently available national statistics of borrowing and lending in communities, and of national balance sheets. It covers 17 countries, including practically all those for which such data are now available together with two for which data have been presented in the past. H. Enzer examines a linear growth system by applying a nonnegative output matrix to an age distribution of capital stock, in the paper On A Useful Capital Growth Matrix.
