The seminal paper by Becker and Murphy (1988) proposed a model acknowledging both addiction and rationality in the consumption of addictive goods. We extend this rational addiction model to include two addictive consumption goods, where the goods may be substitutes or complements, and may...

From questionnaire data it is evident that the number of alternatives unemployed workers consider, i.e. their choice set size, varies substantially. A binomial model is formulated for choice set size, where individual characteristics are used as explanatory variables for observed large variation...

For modeling complete female fertility we propose a zero-and-two-inflated count data model, which accounts for a relative excess of both zero and two children. As the underlying distribution of counts we use the standard Poisson distribution and the more general Gamma count distribution. We...

When modelling demand for addictive consumption goods, the most widely used framework is the rational addiction model proposed by Becker and Murphy. This paper extends the rational addiction model to include two addictive consumption goods, alcohol and cigarettes, and using aggregate annual time...

We propose an extension of the often used rational addiction model. Our model includes both legal and illegal cigarettes. The model is tested on a Swedish data set covering the aggregate legal and illegal cigarette markets. When we treat legal and illegal cigarettes as independent demand...
