The Coase Theorem, or the Coasian Lens? An Application to GMO Regulation

We develop a property rights-transaction costs framework called the Coasian Lens (CL). We argue the CL captures Coase's seminal ideas (1937; 1960) more closely than the Coase Theorem. We use the CL to examine how regulation of genetically modified organisms (GMOs) may affect contract structures in the global agri-food chain.
