We describe a dynamic extension of Allen and Gale (1989)'s optimal security design model in which producers can tranche the stochastic cash flows they generate at a cost. Lowering security creation costs in that environment leads to more financial investment, but it has ambiguous effects on capital formation, output, and aggregate productivity. Much of the investment boom caused by increased securitization activities can, in fact, be spent on securitization costs and intermediation rents, with little or even negative effects on development and productivity.
We describe a dynamic extension of Allen and Gale (1989)'s optimal security design model in which producers can tranche the stochastic cash flows they generate at a cost. Lower tranching costs in that environment lead to capital deepening and raise aggregate output. The implications of lower tranching costs for TFP, on the other hand, are fundamentally ambiguous.
