During the last decade, the econometric study of investment behaviour has developed from the descriptive construction of empirical investment equations, as first performed by J. Tinbergen in his well-known 19- publication: 'A Method and its Application to Investment Activity', to the empirical testing of increasingly explicit theories of production behaviour. It was principally D. Jorgenson who gave a great push to this intensified interest in micro-economic investment, with his famous 1965-paper: 'Anticipation and Investment Behaviour', in which he formulated a pure neoclassical model of...

Information technique as a profession is still so young, that few opinions have settled. The influence of the new possibilities in infor mation technique on the functioning of organisations is so little under stood, that important questions like: what is the potential of a com puter in the firm, will management ultimately be replaced by one man-with-a-keyboard, remain unanswered. Many people are convinced that the impact of computers on the way we manage our enterprises will be enormous, but they grope in the dark for qualitative and quantitative measures to describe it. Naturally, at this...

It was R. Frisch, who in his publications 'Correlation and Scatter Analysis in Statistical Variables' (1929) and 'Statistical Confluence Analysis by means of Complete Regression Systems' (1934) first pointed out the complications that arise if one applies regression analysis to variables among which several independent linear relations exist. Should these relationships be exact, then there exist two closely related solutions for this problem, viz. 1. The estimation of 'stable' linear combinations of coefficients, the so-called estimable functions. 2. The dropping of the wen-known condition of...

In the 'sixties, the reproduction model was often the subject of analysis and discussion in economic literat ure. Discussion was by criticism of the neo-classical concept of capital as well as by a renewed interest in the labour theory of value. Criticism of the use of a homogeneous concept of capital resulted in the re switching debate as it is called, where the positing of problems is limited, and the results are ultimately meagre. The renewed interest in the labour theory of value opened interesting perspectives, at least if one rejects the rather fruitless debate on Marx's transform ation...

Every day people frequently have to make a choice. For practical and scientific reasons therefore it is interesting to know what choices they make and how they arrive at them. An approach to this question can be made via psychology. However, it is also possible to approach it on a more formal basis. In this book Dr. Wedde pohl describes the logical structure of an individual's rational choice. It is this formal, logical approach to the decision problem that makes the book interesting reading matter for all those who are engaged in the study of individual choice. The introduction apart this...
