The nickname of the Lehman CEO Dick Fuld was 'The Gorilla of Wallstreet'. In Gorillas, Markets and the Search for Economic Values the Nyenrode academic community discusses the five years following the Lehman Brothers demise (as a metaphor for the ongoing financial crises).We try to understand the complexities of the financial crises for future research and lecturing. Do the crises challenge common wisdom? Can long-standing theoretical models stand the test of ongoing turbulences in markets and financial institutions? Are relationships between governments, markets and regulation in dire need of redefinition? What are explanations and remedies for the crises? In short: what's new?Four themes are discussed that could spark theoretical innovations. We offer governments, regulators, financial institutions, shareholders, companies, and clients suggestions, tools, and mentalities to address the crises. The themes are:* The blame game* Psychology and culture* Reinventing regulation and overcoming information asymmetry* Other business models, new values
