We study a series of growth models in which households' preferences display `jealousy' or `external habits': a negative dependence on average consumption. We argue that accounting for consumption externalities in growth models requires consideration of both their static and dynamic effects. In a...

Studies of inequality often ignore resource allocation within the household. In doing so they miss an important element of the distribution of welfare that can vary dramatically depending on overall environmental and economic factors. Thus, measures of inequality that ignore intra household...

We quantified the relative importance of the precautionary motive in determining savings. Existing empirical evidence suggests that the impact of precautionary savings is small if one uses a subjective measure of uncertainty about next year income. However, other studies use an ‘objective'...

The welfare implications of direct-to-consumer advertising (DTCA) have garnered considerable attention and are complicated since the consumer delegates some decision-making authority to the physician, who is exposed to advertising as well. In this paper, I develop and estimate a structural model...

The market for payments is an important two-sided one, where consumers benefit from increased merchant acceptance of payment cards and vice versa. The dependence between the decisions that are made on each side of the market results in various network externalities that are often discussed but...

Platforms often display their products ahead of third-party products in search. Is this due to consumers preferring platform-owned products or platforms engaging in self-preferencing by biasing search towards their own products? What are the welfare implications? I develop a structural model of...

Empirical and theoretical research on the demand for health inputs has been, and still is, extensive. However, much of the focus of discrete choice studies has been on the effects of various attributes on household choice of e.g. health care provider and little attention has been paid to...

Many consumer behaviors are both addictive and social. Understanding how these two phenomena interact informs basic models of human behavior, and matters for policymakers when the behavior is regulated. I develop a new model of demand that incorporates both addiction and social interactions and...

In Europe, company cars are offered by employers as fringe benefits to their employees at a lower price than employees pay in the car market, mainly due to favourable taxation of company cars. We analyse the welfare effects of favourable taxation of company cars for the Netherlands. The...
