The paper presents a theory of the demand for money that combines a special case of the shopping time exchange economy with the cash-in-advance framework. The model predicts that both higher inflation and financial innovation - that reduces the cost of credit - induce agents to substitute away...

Research efforts towards new energy sources and towards the efficiency of energy use will be vital to reducing CO2 abatement costs in the long term. Can such efforts be induced by price instruments? Economists often cite induced technological change as a possible consequence of environmental...
