Firms having significant shareholdings in one another is not an unusual phenomenon in countries where the law admits such ownership arrangements, like Sweden and Japan. In this paper the role of cross-ownership as means for deterring takeovers is examined in the framework of a simple two-firm,...

This paper studies the relative importance of tax incentives as merger motives in the Swedish industry during the period 1983-1987. Several econometric models are estimated and statistical tests performed. The tax-hypothesis is contrasted with an alternative hypothesis, suggested by Jensen,...

This note elaborates an extension of the paper "Social Norms, the Welfare State, and Voting" by Lindbeck, Nyberg, and Weibull [1]. That paper studies the effects of a social norm against living off others work. In the welfare-state context of their model, this means that individuals who live on...

We survey the literature on social networks by putting together the economics, sociological and physics/applied mathematics approaches, showing their similarities and differences. We expose, in particular, the two main ways of modeling network formation. While the physics/applied mathematics...

This study examines the determinants of citation success among authors who recently published their work in economic history journals. We find that full professors, authors from non-economic history departments, and authors working in Anglo-Saxon countries are all more likely to get cited than...

We study the political opinions of Swedish social scientists in seven disciplines. A survey was sent to 4,301 academics at 25 colleges and universities, which makes the coverage of the disciplines included more or less comprehensive. When it comes to party sympathies there are 1.3 academics on...

We develop a model where information about jobs is essentially obtained through friends and relatives, i.e. strong and weak ties. Workers commute to a business center to work and to interact with other people. We find that housing prices increase with the level of social interactions in the city...

We develop a model in which non-white individuals are defined with respect to their social environment (family, friends, neighbors) and their attachments to their culture of origin (religion, language), and in which jobs are mainly found through social networks. We find that, depending on how...

Criminals are embedded in a network of relationships. Social ties among criminals are modeled by means of a graph where criminals compete for a booty and benefit from local interactions with their neighbours. Each criminal decides in a non-cooperative way how much crime effort he will exert. We...
