This paper investigates institutions for the creation and transmission of knowledge as efficient resource allocation mechanisms. By looking at Science and Technology it develops a two way classification. Science, is a non market allocation mechanism, where knowledge is treated as a pure public...

There are two broad criteria by which one can judge humanity's success in feeding itself: (i) the proportion of people whose access to basic nutritional requirements is secure; and (ii) the extent to which global food production is sustainable. Even though the two are related, they have usually...

We are interested in three related questions: (1) How should accounting prices be estimated? (2) How should we evaluate policy change in an imperfect economy? (3) How can we check whether intergenerational well-being will be sustained along a projected economic programme? We do not presume that...

In this article the authors define sustainable development as an economic programme along which social well-being does not decline over time. It can be shown that the requirement is equivalent to the maintenance of a comprehensive measure of wealth, where an economy’s wealth is defined to...

This paper articulates and applies frameworks for examining whether consumption is excessive. We consider two criteria for the possible excessiveness (or insufficiency) of current consumption. One is an intertemporal utility-maximization criterion: actual current consumption is deemed excessive...

This paper is about net national product (NNP). The authors are concerned with what NNP means, what it should include, what it offers us and, therefore, why we may be interested in it. They show that NNP, properly defined, can be used as a gauge for project evaluation, but they also show that it...

In any dynamic model of the economy with changing population, the latter should properly be one of the state variables of the system. It enters both in the maximand, at least under total utilitarianism, and into the production function in one way or another. If population growth is exponential...
