The recent financial crisis highlighted the limits of the "originate to distribute" model of banking, but its nexus with the macroeconomy remains unexplored. I build a business cycle model with banks engaging in credit risk transfer (CRT) under informational externalities. Markets for CRT provide liquidity insurance to banks, but the emergence of a pooling equilibrium can also impair the banks’ monitoring incentives. In normal times and in face of standard macro shocks the insurance benefits of CRT prevail and the business cycle is stabilized. In face of financial/liquidity shocks the extent of informational asymmetries is larger and the business cycle is amplified. The macro model with CRT can also reproduce well a number of macro and banking statistics over the period of rapid growth of this banks’ business model.
Trust in policy makers fluctuates signi
cantly over the cycle and affects the transmission mechanism. Despite this it is absent from the literature. We build a monetary model embedding trust cycles; the latter emerge as an equilibrium phenomenon of a game-theoretic interaction between atomistic agents and the monetary authority. Trust affects agents' stochastic discount factors, namely the price of future risk, and through this it interacts with the monetary transmission mechanism. Using data from the Eurobarometer surveys, we analyze the link between trust and the transmission mechanism of macro and monetary shocks: Empirical results are in line with theoretical ones.
In the event of a Greek exit from the Eurozone, the stronger members of the monetary union, especially Germany, face at least two risks: First, the debt of the Greek National Bank vis-à-vis the Eurosystem of central banks will most likely be lost. Secondly, the large flow of capital from Greece and other periphery countries to Germany will accelerate inflation.
