Financial Innovation and Portfolio Risks
- (pp. 398-401)
AbstractI illustrate the effect of financial innovation on portfolio risks by using an example with risk-sharing needs and belief disagreements. I consider two types of innovation: product innovation, formalized as an expansion of new financial assets; and process innovation, formalized as a reduction in transaction costs. When belief disagreements are large, both types of innovation increase portfolio risks. Moreover, endogenous financial innovation is directed towards speculative assets that increase portfolio risks.
