As long as Portugal was on the gold standard, the Bank of Portugal, sought to stabilize the currency at the exchange rate to which the country was committed. Because it was subject to political and other constraints, the Bank carried out discount rate interventions excessively sparingly,...

This paper develops a model of a small open economy integrated in a monetary union. The model incorporates the standard nominal and real frictions in the literature. The parameters of the model are calibrated to the Portuguese data and the effects of the standard monetary policy shock are studied.

We develop a dynamic general equilibrium model for the positive and normativeanalysis of macroprudential policies. Optimizing financial intermediaries allocate theirscarce net worth together with funds raised from saving households across two lendingactivities, mortgage and corporate lending....

Based on Contingent Claims Analysis, this paper develops a method to monitor systemic risk in the European banking system. Aggregated Distance-to-Default series are generated using option prices information from systemically important banks and the STOXX Europe 600 Banks Index. These indicators...

We study the macroeconomic effects of bank runs in a neoclassical growth model with a fully microfounded banking system. In every period, the banks provide insurance against idiosyncratic liquidity shocks, but the possibility of sunspot-driven bank runs distorts the equilibrium allocation. In...

This paper develops a dynamic stochastic general equilibrium model to examine the impact of macroprudential regulation on bank’s financial decisions and the implications for the real sector. I explicitly incorporate costs and benefits of capital requirements. I model an occasionally binding...

Infrequent price changes at the firm level are now well documented in the literature. However, a number of issues remain partly unaddressed. This paper contributes to the literature on price stickiness by investigating the lags of price adjustments to different types of shocks. We find that...

Thanks to recent findings based on survey data, it is now well known that firms differ from each other with respect to their price-reviewing strategies. While some firms review their prices at fixed intervals of time, others prefer to perform price revisions in response to changes in economic...

When the zero lower bound on nominal interest rates binds, monetary policy cannot provide appropriate stimulus. We show that in the standard New Keynesian model, tax policy can deliver such stimulus at no cost and in a time-consistent manner. There is no need to use inefficient policies such as...
