Technology adoption and herding behavior in complex social networks
Švarcová, Natalie; Švarc, Petr - 2008
Using a simple computational model, we study consequences of herding behavior in population of agents connected in networks with different topologies: random networks, small-world networks and scale-free networks. Agents sequentially choose between two technologies using very simple rules based...

Artificial Intelligence and the clustering of human capital: The risks for Europe
Brey, Björn; Van der Marel, Erik - 2023
Europe trails the global frontier of productivity growth and the region's trend is sluggish. Much prospective economic growth for Europe is likely to come from AI and its adoption by European firms which is projected to shoot up the productivity trend. For such AI-generated growth to work, high...

Parting with "blue monday": Preferences in home production and consumer responses to innovations
Witt, Ulrich; Woersdorfer, Julia Sophie - 2011
How can economic theory explain the reasons why consumers adopt innovations? Using the example of innovations in washing machines two approaches are compared. The first focuses in the manner of household production theory on changes in constraints without specifying preferences, leading to the...

Will imitators follow pioneer consumers in the adoption of solar thermal systems? Empirical evidence for North-West Germany
Wörsdorfer, Julia Sophie; Kaus, Wolfhard - 2010
In Germany, solar thermal systems (STS) have only diffused to a minor extent yet. This paper analyzes, which demand side factors are decisive for the further proliferation of this environmentally benign technology. Making use of a consumer survey in North-West Germany in 2007, we examine the...

Panel estimation of state dependent adjustment when the target is unobserved
von Kalckreuth, Ulf - 2008
Understanding adjustment processes has become central in economics. Empirical analysis is fraught with the problem that the target is usually unobserved. This paper develops, simulates and applies GMM methods for estimating dynamic adjustment models in a panel data context with partially...
