We study an endogenous growth model where a profit-motivated R and D sector coexists with the introduction of free blueprints invented by philanthropists. These goods are priced at marginal cost, contrary to proprietary ones which are produced by a monopoly owned by the inventor. We show that...

To introduce a novel generalization of economies of scope, the paper develops a theory of average cost reductions based on enabling products to have multiple features or functions. The process is labelled economies of score. Focusing production costs on the details of product features can lead...

This paper examines how revenues from a natural resource interact with growth and welfare in an overlapping generations model with altruism. The revenues are allocated between public productive services and direct transfers to members of society by spending policies. We analyze how these...

This paper considers one altruistic developed country and several heterogeneous developing countries. We demonstrate that the lack of coordination between countries in tackling climate change finds an optimal solution if developing countries can expect to receive development aid transfers from...

We study a growth model with two types of agents who are heterogeneous in their degree of family altruism. We prove that every equilibrium path converges to a unique steady state, and study the effect of altruism on the properties of steady-state equilibrium. We show that aggregate income is...

Intergenerational altruism and contemporaneous cooperation are both important to the provision of long-lived public goods. Equilibrium climate protection may depend more sensitively on either of these considerations, depending on the type of policy rule one examines. This conclusion is based on...

We analyze the role of "the" utility discount rate and its implications to generation-specific and societal altruism and egoism, respectively, in a neoclassical framework. It is worked out clearly, that two different utility discount rates have to be distinguished: An (inverse)...

The future effects of climate change may induce increased intergenerational altruism. But will increased intergenerational altruism reduce the threat of climate change? In this chapter we investigate this question. In a second-best setting with insufficient control of greenhouse gas emissions in...

I compare the relative importance of inter-generational altruism and contemporaneous cooperation, in determining equilibrium climate policy, by imbedding an OLG framework with inter-generational altruism into a differential game between nations. The model uses new representations for the...

Concerns about offspring's life quality are often cited as a motivation for caring about climate change. This paper investigates the hypothesized causal effect of grandparenthood on climate change worries, using panel data surveys among British families. Specifically, we study whether becoming a...
