The contribution of this thesis is to present a framework to analyse firms controlled by more than one board. The literature survey of Chapter 2 revealed that there is little recognition of this phenomenon and no accepted way to investigate firms governed by multiple control centres described as...

Prevailing models of capital markets capture a limited form of social influence and information transmission, in which the beliefs and behavior of an investor affect others only through market price, information transmission and processing is simple (without thoughts and feelings), and there is...

We apply network analysis to trace patterns of information transmission in an electronic limit order market. If market orders or large executable limit orders are submitted by informed traders, then resulting star-shaped or diamond-shaped patterns ndash; or trading networks ndash; should be...

We present a model of opinion formation where individuals repeatedly engage in discussion and update their opinion in a social network similarly to the DeGroot model. Abstracting from the standard assumption that individuals always report their opinion truthfully, agents in our model may state...

This paper investigates whether the setting of the German top income tax burden is affected by the composition of the Federal Government in terms of connectedness with the national (academic) elite and company network from 1958 to 2011. The results reveal that the percentages of university...

We propose a stylised dynamic model to understand the role of social networks in the phenomenon we call "globalization." This term refers to the process by which even agents who are geographically far apart come to interact, thus being able to overcome what would otherwise be a fast saturation...

This paper undertakes a critical review of existing spillover analyses and proposes a unique analytical framework for examining technological spillovers in a manufacturing industry setting. The proposed framework overlaps three different literature strands; cluster and network dynamics,...

Suppose that homogenous agents fully consume their time to invent new ideas and learn ideas from their friends. If the social network is complete and agents pick friends and ideas of friends uniformly at random, the distribution of ideas’ popularity is an extension of the Yule-Simon...

Network formation is often said to be driven by social capital considerations. A typical pattern observed in the empirical data on strategic alliances is that of small world networks: dense subgroups of firms interconnected by (few) clique-spanning ties. The typical argument is that there is...

A pressing reality which companies must deal with is the accelerated emergence of the networks, physical or virtual, which play an increasingly important role in business. Networks configuration determines the markets dynamics, business organisation. However, the access to knowledge is not...
