in this article, a multi-objective function for placement of distributed generation (dg) and capacitors with thetap setting of under load tap changer (ultc) transformer is introduced. most of the recent articles have paidless attention to dg, capacitor placement and ultc effects in the distribution network simultaneously. insimulations, a comparison between different modes was carried out with,...

Many industries characterize the "network externalities" or "network effects," which highlight that the benefit that a consumer derives from the use of a good often depends on the number of other consumers purchasing compatible items. The four essays in this dissertation examine some important issues in industries in the presence of network effects. In the first essay, the influence of network ...

Building on the Resource-Based View of the firm, we advance the idea that a firm’s customer network can be a strategic asset. We suggest that network effects are a function of network size (i.e., installed customer base) and network strength (i.e., the marginal impact of a unit increase in network size on demand). We empirically study these network effects in the 16-bit home video game industry...

Individuals form teams to produce an output. The quality and quantity of a team’s output depends on the ability and the effort level of its members. The ability of individuals as well as their work ethic is however imperfectly known. In such an environment, individuals wishing to form a new team can get information about each other from the network of past collaborators. The paper carries out a...

In this paper we study consumption network effects. Does the consumption of our peers affect our own consumption? How large is such effect? What are the economic mechanisms behind it? We use long panel data on the entire Danish population to construct a measure of consumption based on administrative tax records on income and assets. We combine tax record data with matched employer-employee data...

Preparing for the spread of infectious diseases is an important government function. The great influenza pandemic of 1918 killed about 100 million people, and in more recent times, SARS and avian influenza have affected several countries. Agent-based models can be used to predict the spread of new diseases within a population. However, the behaviour of such models is dependent on the topology o...
