The fourth essay focuses on regional economic development, using a model of monopolistic competition. This essay stresses the importance of including the variety of service provision when analyzing regional economic performance. The fifth essay contains an empirical analysis of the market for office space in the Stockholm region. The dynamic behavior in the market is analyzed, using a small sample data set.
