The paper offers a proof that expected utility maximisation with logarithmic utility is a dominant preference in the biological selection process in the sense that a population following any other preference for decision-making under risk will, with a probability that approaches certainty,...

We analyse the determination of taxes on harmful goods when consumers have self-control problems. We show that under reasonable assumptions, the socially optimal corrective tax exceeds the average distortion caused by self-control problems. Further, we analyse how individuals with self-control...

The present paper studies the growth and efficiency consequences of pension funding with individual retirement accounts in a general equilibrium overlapping generations model with idiosyncratic lifespan and labor income uncertainty. We distinguish between economies with rational and hyperbolic...

Equilibrium prices behave quite differently if consumers single-purchase (buy either Time Magazine or Newsweek) or if some consumers multi-purchase (buy both). Prices are strategic complements under single-purchase, and increase with magazine quality. In a multi-purchase regime prices are...

Museums have many different goals beyond efficiency such as social equity, financial revenue, attracting donors and gaining international, regional or local prestige. Various pricing schemes are being discussed with the aim of reaching these goals. The classical ones are entry prices and free...

Several empirical studies provide evidence that their actual health state affects people's attitudes towards health and medical care in hypothetical health states. In the tradition of behavioural economics this paper considers the actual health state as a point of reference and builds a model...

Collective consumption decisions taken by the members of a household may prove inefficient. The impact on market performance depends on whether household inefficiencies are caused by inefficient net trades with the market or by inefficient distribution of resources within households. Inefficient...

We study implications of habit formation for optimal taxation. First, we show that taxation problems with habit formation can be analyzed using dynamic programming techniques. Second, we derive optimal labor and savings wedges for habit formation preferences. We show that habit formation...
