Book Description
Information is crucial to make good decisions, but obtaining and providing information often comes at a cost. Consumers and firms both need to balance these costs and benefits of obtaining and providing information in order to make the best decisions. The research in this thesis investigates several questions that pertain to the acquisition and provision of information. In the first part of this thesis it is assumed that consumers are not fully informed about the prices or availability of a product they want to buy. Consumers can search for information, but this comes at a cost. At the same time, shops can influence these costs. In the first two studies in this part, shops have the possibility to advertise. An advertisement provides information to consumers and reduces the search costs. We investigate, among other things, the pricing behavior of shops and the relation between search and advertising. The third study in this part of the thesis considers the location choice of shops. Locating together in a shopping mall reduces the search costs of consumers. This increases the competition between shops and lowers the prices, but we show that at the same time the sales volume increases. The total effect of locating together on profits is generally positive. The second part of this thesis considers director ties (also named interlocks). A director who has several directorships in different firms can serve as an information bridge between the different firms. At the same time, interlocking directors are busy and form a homogenous group. Data from the Netherlands show that in The Netherlands the positive information providing effect of interlocks is outweighed by a negative busyness and homogenous group effect.

Book Description
Finite mixture distributions are a weighted average of a finite number of distributions. The latter are usually called the mixture components. The weights are usually described by a multinomial distribution and are sometimes called mixing proportions. The mixture components may be the same type of distributions with di®erent parameter values but they may also be completely different distributions. Therefore, finite mixture distributions are very °exible for modeling data. They are frequently used as a building block within many modern econometric models. The specification of the mixture distribution depends on the modeling problem at hand. In this thesis, we introduce new applications of finite mixtures to deal with several di®erent modeling issues. Each chapter of the thesis focusses on a specific modeling issue. The parameters of some of the resulting models can be estimated using standard techniques but for some of the chapters we need to develop new estimation and inference methods. To illustrate how the methods can be applied, we analyze at least one empirical data set for each approach. These data sets cover a wide range of research fields, such as macroeconomics, marketing, and political science. We show the usefulness of the methods and, in some cases, the improvement over previous methods in the literature.
