In a New Keynesian model with the BGG accelerator and risk shocks, we show that violations of Tinbergen's Rule and strategic interaction between economic authorities undermine the effectiveness of monetary and financial policies. Separate monetary and financial policy rules produce higher welfare than a monetary rule augmented with credit spreads. The latter yields a tight money-tight credit regime in which the interest rate responds too much to inflation and not enough to credit. Reaction curves for the policy-rule elasticities are nonlinear, which reflects shifts in these elasticities from strategic substitutes to complements. The Nash equilibrium is inferior to the Cooperative equilibrium, both are inferior to a first-best outcome, and both might produce tight money-tight credit regimes.

Reglas separadas de política monetaria y financiera producen un bienestar mayor que una regla monetaria aumentada con spread crediticios.

Las curvas de reacción de las elasticidades de las reglas de política son no lineales, lo cual refleja cambios en estas elasticidades de substitutos estratégicos a complementos.

We develop a two-country DSGE model with global banks to analyze the role of crossborder banking flows on the transmission of a quality of capital shock in the United States to emerging market economies (EMEs). Banks face a moral hazard problem for borrowing from households. EME's banks might be risky: they can also be constrained to borrow from U.S. banks. A negative quality of capital shock in the United States generates a global financial crisis. EME's macroprudential policy that targets non-core liabilities makes the domestic economy resilient to the volatility of cross-border banking flows and makes EME's households better-off.
We estimate the impact of fuel-commodity price shocks on inflation and inflation expectations for eight Latin American countries in which monetary policy follows inflation-targeting frameworks. We use Bayesian Vector Autoregressive models (BVARs) and data from 2005 and up to 2022 to quantify these impacts. We find that the fuel-price shocks are significant in all cases and the response ranges between 0.01 and 0.04 percentage points of inflation, following a 1 p.p. shock to fuel prices. A variance decomposition exercise shows that more than 50% of the outburst in inflation that these countries experienced in 2021 and 2022 can be attributed to the shock in global fuel prices. These results are robust to changes in the specification that include additional controls, different commodity price measures, different lag structures, and alternative ordering.
