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...

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...

This chapter reviews the recent theoretical and empirical economic literature on migrants' remittances. It is divided between a microeconomic section on the determinants of remittances and a macroeconomic section on their growth effects. At the micro level we first present in a fully harmonized...

It has been shown that higher capital taxes can have a growth-enhancing effect when combined with a revenue-compensating cut in wage taxes (Uhlig and Yanagawa 1996; European Economic Review 40, 1521–1540) or with an expansion in productivity-increasing public services (Rivas 2003; European Economic...

In this paper, we study the role of risk-sharing in entrepreneurship-driven innovation. Studying entrepreneurship and innovation entails modeling an occupational choice and an effort choice. Risk-sharing may increase the number of individuals who become entrepreneurs by limiting the downside...

We argue that with interdependent utility functions growth can lead to a decline in total welfare of a society if the gains from growth are sufficiently unequally distributed in the presence of negative externalities, i.e., envy.

We develop an overlapping generations growth model in which the individuals care about the environment. Many environmental policies suffer from institutional failures. We focus on the failure resulting from the delegation by the government of the exercise of the environmental policy to an...

How does organizational higher purpose affect employee behavior and firm output? We develop an optimal-contracting model which shows that pursuing organizational higher purpose dissipates agency frictions, lowers wage costs and elicits higher employee effort. The effect on profits, however,...
