We propose a model of economic growth in which technological progress is modelled as an expanding random network of ideas. New ideas are created by combining successful old ideas. Old ideas are chosen according to their visibility as ideas, success as generators of innovations and age but the...

This paper investigates the efficiency of household investment decisions in a unique dataset containing the disaggregated wealth and income of the entire population of Sweden. The analysis focuses on two main sources of inefficiency in the financial portfolio: underdiversification of risky...

The present paper is an extension of Ghiglino and Shell [7] to the case of imperfect consumer credit markets. We show that with constraints on individual credit and only anonymous (i.e., non-personalized) lump-sum taxes, strong (or “global”) irrelevance of government budget deficits is not...

This paper analyses the effects of so-called "green" tax reforms on a small, open economy producing an imperfect substitute for foreign goods, using an intertemporal general equilibrium model. The labour market is characterised by union wage setting, and a fixed exchange rate implies wage...

This paper analyses the effects of a carbon tax on a small open petroleum producing economy, using an aggregate intertemporal general equilibrium model with differentiated products. The long run effects on welfare and capital accumulation of both a unilateral and an international carbon tax are...

Equilibrium paths in an economy of overlapping generations are determinate. Time is either discrete or continuous; in either case, it extend into the infinite future and, possibly, the infinite past. There is one, nonstorable commodity at each date. The economy is stationary; intertemporal...

This paper investigates the efficiency of household investment decisions in a unique dataset containing the disaggregated wealth and income of the entire population of Sweeden.

In this paper we investigate the effects of government budget deficit restrictions in a finite horizon model with imperfect consumer credit market. When financial markets are perfect anonymous lump-sum taxes are sufficient to achieve irrelevance of government budget deficit restrictions in the...

We propose a model of economic growth in which technological progress is modelled as an expanding random network of ideas. New ideas are created by combining successful old ideas. Old ideas are chosen according to their visibility as ideas, success as generators of innovations and age but the...

This paper explores the extent to which markets constrain intertemporal preferences. First, we show that without transaction costs, agents are immune to exploitation in competitive markets. In particular, a sequence of trades leaving any market participant strictly worse off (termed a money...
