Is systematic monetary policy a driver of the forward premium puzzle, i.e. the tendency of high interest-rate currencies to appreciate, thus strongly violating Uncovered Interest Parity (UIP)? We address this question by studying a battery of monetary policy rules in a small open economy that is...

This paper models the interaction between international trade finance and monetary policy in open economies and shows that trade finance affects the propagation mechanism of all macroeconomic shocks that are identified to be drivers of business cycles in advanced economies. The model is...

When does the combination of flexible exchange rates and domestic inflation-oriented monetary policy guarantee insulation from global financial conditions? We examine a dynamic global game model of international portfolio flows where, for some combination of parameters, the unique equilibrium...

Since the global financial crisis of 2008, macroprudential instruments have attracted an increasing amount of attention as potentially the best tools for stabilizing boom-and-bust cycles. This is because, in contrast to short-term interest rates, macroprudential instruments are regarded as...

The liquidity trap is synonymous with ineffective monetary policy. The common wisdom is that, as the short-term interest rate nears its effective lower bound, monetary policy cannot do much to stimulate the economy. However, central banks have resorted to alternative instruments, such as QE,...

Assigning a discretionary central bank a mandate to stabilize an average inflation rate - rather than a period-by-period inflation rate - increases welfare in a New Keynesian model with an occasionally binding lower bound on nominal interest rates. Under rational expectations, the...

Is monetary policy less effective in boosting aggregate demand and output during periods of persistently low interest rates? This paper reviews the reasons why this might be the case and the corresponding empirical evidence. Transmission could be weaker for two main reasons: (i) headwinds, which...

We assess how a major, unconventional central bank intervention, Draghi's "whatever it takes" speech, affected lending conditions. Similar to other large interventions, it responded to adverse financial and macroeconomic developments that also influenced the supply and demand for credit. We...

Informality is an entrenched structural trait in emerging market economies, despite of the progress achieved in macroeconomic management. Informality determines the behavior of labour markets, financial access and the productivity of the overall economy. Therefore it influences the transmission...

We provide a theory of the limits to monetary policy independence in open economies arising from the interaction between capital flows and domestic collateral constraints. The key feature is the existence of an "Expansionary Lower Bound" (ELB), defined as an interest rate threshold below which...
