Book Description
Access to relevant external knowledge is crucial for a firms' competitiveness in innovation-driven industries. This thesis focuses on how different forms of proximity affect a firm's ability to access such knowledge. We consider the influence of being co-located in space, of being embedded in a network, and of being active in similar knowledge domains. By integrating these three proximity perspectives, we contribute to various disciplines such as economic geography, organizational sociology and innovation studies. Further, we investigate the make, buy or ally strategies that pharmaceutical firms employ to maximize the probability of innovation (finding new drugs). Our findings suggest that firms employ multiple governance structures simultaneously, even when targeting similar innovations. These insights contribute to our understanding of the boundaries of the firm.

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
Believing in a single model may be dangerous, and addressing model uncertainty by averaging different models in making forecasts may be very beneficial. In this thesis we focus on forecasting financial time series using model averaging schemes as a way to produce optimal forecasts. We derive and discuss in simulation exercises and empirical applications model averaging techniques that can reproduce stylized facts of financial time series, such as low predictability and time-varying patterns. We emphasize that model averaging is not a "magic" methodology which solves a priori problems of poorly forecasting. Averaging techniques have an essential requirement: individual models have to fit data. In the first section we provide a general outline of the thesis and its contributions to previ ous research. In Chapter 2 we focus on the use of time varying model weight combinations. In Chapter 3, we extend the analysis in the previous chapter to a new Bayesian averaging scheme that models structural instability carefully. In Chapter 4 we focus on forecasting the term structure of U.S. interest rates. In Chapter 5 we attempt to shed more light on forecasting performance of stochastic day-ahead price models. We examine six stochastic price models to forecast day-ahead prices of the two most active power exchanges in the world: the Nordic Power Exchange and the Amsterdam Power Exchange. Three of these forecasting models include weather forecasts. To sum up, the research finds an increase of forecasting power of financial time series when parameter uncertainty, model uncertainty and optimal decision making are included.
