In a hold-up experiment designed to test theoretical predictions following from Hart (1995) and deMeza/Lockwood (1998) regarding investment behavior Sonnemans et al. (2001) (SOS) find only a partial confirmation of theory. According to SOS these deviations from standard theory can be explained...

We conducted six treatments of a standard moral hazard experiment with hidden action. All treatments had identical Nash equilibria. However, the behavior in all treatments and periods was inconsistent with established agency theory (Nash equilibrium). In the early periods of the experiment,...

Recent research has shown the usefulness of social preferences for explaining behavior in laboratory experiments. This paper demonstrates that models of social preferences are particularly powerful in explaining behavior if they are embedded in a setting of heterogeneous actors with...

This note analyzes the Bertrand duopoly with constant but asymmetric marginal costs on a market with homogenous products. It is shown that there exist some equilibria that are ignored in the literature on IO. In addition, in this setting (perfectly or nearly perfectly) competitive equilibria exist.

Hart and Moore (2008) argue that varying degrees of flexibility in contracts induce differing reference points and aspiration levels for parties' shares of a transactions total surplus. As a consequence, a trade-off between adaptational flexibility and the prevention of distributional conflicts...
