This article summarizes some propositions regarding economic dynamics and implications of two-way altruism, on the basis of the human-capital-based OLG model of Ehrlich and Lui (1991) and Ehrlich and Kim (2007) with application of a modified, fertility-endogenized definition of linearly...

We evaluate the social welfare loss (WL) that arises in an oligopolistic industry under technological competition and product differentiation. The main novelty of our approach concerns the decomposition of the WL into `dynamic' losses (from too little cost reduction and an inappropriate number...

‘Green’ markets represent a means through which public goods can be privately provided. A green product is an impure public good consisting of a private good (e.g., rain forest honey) bundled with a jointly produced public good (e.g., biodiversity protection). In the context of ecosystem...

In a world of endogenous fertility, where the number of descendants is an integral part of the economic allocation, the traditional concept of Pareto-optimality cannot be applied any longer: the number of individuals to be present on earth may vary between any two allocations we wish to compare....

This paper combines information efficiency with the economists’ usual sense of the word “efficiency”, i.e. the allocation of resources to their most profitable expected use and at the lowest cost in terms of resources employed. The paper addresses dynamic efficiency, the ability of a...

This paper reports a research project carried out on behalf of the Ministry of Agriculture and Forestry New Zealand designed to scope the issue of water efficiency in New Zealand and demonstrate where the most significant gains in efficiency can occur. The paper describes the efficiency...

We study the macroeconomic effects of rational asset bubbles in an overlapping-generations economy where asset trading requires specialized intermediaries and where agents freely choose between working in the production or in the financial sector. Frictions in the market for deposits create...
