Englmaier, Florian; Reisinger, Markus - 2006
The industrialization process of a country is often plagued by a failure to coordinate investment decisions. Using the Global Games approach we can solve this coordination problem and eliminate the problem of multiple equilibria. We show how appropriate information provision enhances efficiency....

Kunte, Sebastian; Wollni, Meike - 2015
Contract flexibility can be expedient for economic exchange in environments with high ambiguity and risk, but may also encourage opportunistic behavior. We run a modified investment game, including the choice between two different contract designs and asymmetric information about the realized...
