Inflation-targeting central banks around the world often state their inflation objectives with regard to the consumer price index (CPI). Yet the literature on optimal monetary policy based on models with nominal rigidities and more than one sector suggests that CPI inflation is not always the...

While flexible exchange rates facilitate stabilisation, exchange rate fluctuations can cause real volatility. This gives policy importance to the causal relationship between exchange rate depreciation and its volatility. An exchange rate may be expected to become more volatile when the...

The author investigates the quantitative importance of the expenditure-switching effect by developing and estimating a structural sticky-price model nesting both producer currency pricing (PCP) and local currency pricing (LCP) settings. The author aims to provide empirical evidence of the...

This paper develops a multi-sector New Keynesian model of a small open economy that includes commodity, manufacturing, non-tradable, and import sectors. Price and wage rigidities are sector specific, modelled à la Calvo-Yun style contracts. Labour and capital are imperfectly mobile across...

In theory, nominal exchange rate movements can lead to “expenditure switching” when they generate changes in the relative prices of goods across countries. This paper explores whether the expenditure-switching role of exchange rates has changed in the current episode of significant global...

Capital flows to emerging market economies (EMEs) have been characterized by high volatility since the 1980s. In recent years (especially since 2003), although gross as well as net capital flows to the EMEs have increased, they could not be absorbed domestically. Overall, savings have flowed...

Unlike common wisdom, sterilized FX purchases under inflation targeting, i.e., those that keep the interest rate at the level targeted by the central bank, generally increase aggregate demand. We resort to a simple model with a credit channel to argue that FX purchases, by funding bank credit,...

This paper studies the effect of exchange rate pass-through on inflation in Tunisia over the period 2001-2009. The authors' objective is to track inflation regimes for the Tunisian economy and to forecast its determinants. Using a Markov-switching approach, the authors identified two main...

We use changes in Brazil's tax on capital inflows from 2006 to 2011 to test for direct portfolio effects and externalities from capital controls on investor portfolios. The analysis is structured based on information from investor interviews. We find that an increase in Brazil's tax on foreign...

This paper analyzes the drivers of international waves in capital flows. We build on the literature on “sudden stops” and “bonanzas” to develop a new methodology for identifying episodes of extreme capital flow movements using quarterly data on gross inflows and gross outflows,...
