The co-author model is introduced by Jackson and Wolinsky (1996, Journal of Economic Theory) as a typical example of the models of network formation. In this note, we study which network is pairwise stable and/or stochastically stable when the number of players is four.

Jackson and Watts (2002, J Econ Theory) study a dynamic process of network formation assuming that each player is myopic. In this note, we study the same dynamic process but assume that each player is farsighted. In particular, we consider a finite-horizon version of such a dynamic process in a...

Simulating the real business cycle models is a popular topic in first-year graduate courses on macroeconomics. Usually, Maple and Matlab are used for this purpose, mainly because they can be used both for solving and for simulating the models. Strulik (2004) demonstrates that Excel can be used...

We experimentally study the effect of a third-person enforcement on a one-shot prisoner’s dilemma game played by two persons, with whom the third person plays repeated prisoner’s dilemma games. We find that when the third person can observe these two persons’ play, the possibility of the...
