Abstract

This paper builds a DSGE model in which future wage assignments are introduced as collateral for risky consumer and housing loans, in addition to standard BGG-type loans to entrepreneurs. Banks face matter-of-fact constraints in funding and lending markets, have liquidity targets, and are subject to a number of macroprudential rules, such as reserve requirements, capital requirements, and regulation on housing loan concessions. The main determinants of actual bank lending spreads are mapped into the model through the introduction of taxes on banking activity, monopolistic competition in a segment of the bank's conglomerate, credit risk, and regulatory and operational costs. The bank operates in the open market, and that is key to the transmission channel of reserve requirements. The model is carefully tailored to Brazil and reproduces the baseline understanding of the transmission channel of monetary policy and of reserve requirements. Macroprudential regulation in the form of capital requirements has important implications for the dynamics of real variables. DSGE modeling, with results analyzed trhough impulse responses. The first draft of the paper presents a calibration and IRFs. We plan to present in the conference a full-fledged estimated version of it, with variance decomposition analysis, historical decomposition of shocks, in addition to scenario studies. Preliminary results with the calibrated version of the model show that our modeling strategy is capable of reproducing the baseline understanding of the transmission channel of monetary policy and of reserve requirements. In addition, macroprudential regulation in the form of capital requirements has important implications for the dynamics of real variables. We also plan to study to effect of changes in risk weights in capital requirements, changes in the remuneration of reserve requirements, and also analyze the transmission of the last financial shock through the eyes of the model.
