AbstractOn survey data from 1999 to 2001 and 2010 to 2012, we estimate the demand for commercial sex among British men. We estimate a zero‐inflated count model, which takes into account the probability of not participating in the sex market and number of times with a prostitute. We find that sex education in school has a negative and significant role in the demand for paid sex. We also find that men with a typical middle‐class income are more likely to buy sex. Travelling abroad or living in London increases the likelihood of British men buying sex.

We model the choice of transportation mode in a simplified Hotelling-like city, with a fixed number of total travellers, fixed road capacity and with no trade-off between when to travel and the time spent in a queue. A person that chooses to take her own car will inflict a congestion cost on all travellers. To get the travellers to internalise these external costs, a congestion charge has to be imposed. We derive an optimal congestion charge within in a discrete-choice framework, with a benevolent government maximising expected tax-adjusted social surplus. The congestion charge to be imposed on private driving, beyond the opportunity cost - equal to the fare on public transportation - is shown to be a weighted average of a Ramsey-like term (capturing the goal to raise public revenue) and a Pigou-term capturing the environmental cost of a person's private driving. This property is similar to the optimal environmental tax derived by Sandmo (1975). However, the behavioural assumption underlying the present framework is quite different from the standard theory of consumer choice adopted by Sandmo.

First published in 1988, this book examines pollution and natural resources in relation to economic analysis. The section on pollution looks at areas such as the main problems in the field at the time, possible remedies and the environmental costs involved. In regards to natural resources, the book considers both the exploitation of non-renewable resources and commercial fishing. The non-technical introduction to the main problems set out in each chapter will appeal to the general reader whilst the formal models and more technical parts make the material equally suitable for more advanced s

In 1988, an early retirement program (AFP) was introduced in Norway for the 66-year-old. Since then, AFP has gradually been extended and by now it covers workers aged 62-66. In this paper we employ a multinominal logit model to study the transition between states in the labour market. The model is estimated on a large panel data set covering the period 1988-2 to 1999-4. The estimated model tracks the development quite well, as also outside sample predictions do. The model is used to assess the future labour market impact of abolishing AFP. We find that by bolishing AFP may increase the labour force participation among older men (55-67) in 2005 from 72 percent in the baseline projection to 83 percent. For females the corresponding increase is from 62 to 67 percent.
