This paper concerns the optimal provision of a state-variable public good, where the global climate is the prime example. The analysis is based on a two-type optimal income tax model with overlapping generations, where people care about their relative consumption. We consider both...

In this paper, we analyze the welfare effects of publicly provided health care in an economy where the consumers have "present-biased" preferences due to quasi-hyperbolic discounting. The analysis is based on a two-type model with asymmetric information between the government and the private...

This paper analyzes optimal differential commodity taxation, together with optimal nonlinear income taxation, in order to deal with positional preferences. It also derives the optimal public provision of private goods both when differential commodity taxation is feasible and when it is not. It...

Recent empirical evidence suggests that between-country social comparisons have become more important over time. This paper analyzes optimal income taxation in a multi-country economy, where consumers derive utility from their relative consumption compared with both other domestic residents and...

This paper concerns public input provision as an instrument for redistribution under international outsourcing by using a model-economy comprising two countries, North and South, where firms in the North may outsource part of their low-skilled labor intensive production to the South. We consider...

This paper concerns optimal nonlinear taxation in an OLG model with two ability-types, where people care about their own consumption relative to (i) other people’s current consumption, (ii) own past consumption, and (iii) other people’s past consumption. We show that intertemporal...

During the 19th century, poor and orphan Swedish children were boarded out. The foster-parents' compensation was determined in English auctions. Some children were re-auctioned. We use historical data from such auctions to study whether informational asymmetry and possibly adverse selection...

This paper concerns optimal income taxation and provision of a state-variable public good under asymmetric information in a two-type overlapping generations model, where people care about their relative consumption. Each individual may compare his/her own current consumption with his/her own...

This paper develops a dynamic model with endogenous labor supply, savings and health capital, where the consumers differ in ability as well as suffer from a self-control problem generated by quasi-hyperbolic discounting. The purpose is to analyze how a paternalistic government, which implements...
