We study a connections model where the strength of a link depends on the amount invested in it and is determined by an increasing strictly concave function. The revenue from investments in links is the value (information, contacts, friendship) that the nodes receive through the network. First,...

We consider a natural generalization of Jackson and Wolinsky's (J Econ Theory 71:44- 74, 1996) connections model where the quality or strength of a link depends on the amount invested in it and is determined by a non-decreasing function of that amount. The information that the nodes receive...

With 23 core econometrics journals now in operation, this study fills a gap in the literature by cataloguing the editorial specifications of each journal, and, more importantly, assessing their impact based on citations to research published in each over the 15-year period beginning in 2001 and...

Criticism of the compensation practice of bonus payments was a key element of the public debate concerning the causes and consequences of the global financial crisis (GFC). Along with the criticism of bonuses in the financial and banking sector, the validity of the performance principle as a...

We study the long-run stability of trade networks in a two-sided economy of agents labelled men and women. Each agent desires relationships with the other type, but having multiple partners is costly. This cost-benefit trade-off results in each agent having a single-peaked utility over the...

We apply the test of Ijiri and Simon (1974) to a large data set of authors in economics. This test has been used by Tol (2009, 2013a) to identify a (within-author) Matthew effect for authors based on citations. We show that the test is quite sensitive to its underlying assumptions and identifies...

We study the structure of pairwise stable networks from a very general point. Rather than assuming a particular functional form of utility, we simply assume that the society is homogeneous, i.e. that agents' utilities differ only with respect to their network position while their names do not...

Funktionale Differenzierung gilt nicht nur als das zentrale Alleinstellungsmerkmal moderner Gesellschaften, sondern auch als eines der wenigen Felder wissenschaftlicher Ehre, auf denen die Systemtheorie Gäste empfängt und nicht auswärts spielt. Als gute Gastgeberin spielt die Theorie in Form...

We study the economic structure of the life of Harry Potter and his co-actors as an economic model that governs the social organization of their economic activities. Our goal is to study and understand the internal consistency of the Potterian economic model and explore the relationships between...
