We lay out a small open economy version of the Calvo sticky price model, and show how the equilibrium dynamics can be reduced to a tractable canonical system in domestic inflation and the output gap. We employ this framework to analyse the macroeconomic implications of three alternative monetary...

We propose that analysis of purchasing power parity (PPP) and the law of one price (LOOP) should explicitly take into account the possibility of ‘commodity points’ – thresholds delineating a region of no central tendency among relative prices, possibly due to lack of perfect arbitrage in...

This paper develops a quantitative, dynamic, open-economy model which endogenously generates high exchange rate volatility, whereas a low degree of exchange rate pass-through (ERPT) stems from both nominal rigidities (in the form of local currency pricing) and price discrimination. We model real...

This Paper develops an empirical model of bilateral exchange rate volatility. We conjecture that for developing economies, external financial liabilities have an important effect on desired bilateral exchange rate volatility, above and beyond the standard Optimal Currency Area (OCA) factors. By...

This paper looks at the responsiveness of a country's export supply to exchange rate changes and measures its quantitative importance by breaking down export adjustments between changes in output levels by existing exporters (intensive margin) and movements due to changes in the number of...

We show that the variables pointed to by the theory of optimum currency areas (OCAs) help to explain patterns of exchange rate variability and intervention across countries. But OCA considerations affect exchange market pressures and intervention in different ways. Exchange market pressures...

Understanding how import prices adjust to exchange rates helps anticipate inflation effects and monetary policy responses. This paper examines exchange rate passthrough to the monthly import price index in South Africa during 1980-2009. A methodological innovation allows various short-run...

A sizeable literature examines exchange rate pass-through to disaggregated import prices but very few micro-studies focus on consumer prices. This paper explores exchange rate pass-through to consumer prices in South Africa during 2002-2007, using a unique data set of highly disaggregated data...

The paper reports results obtained from the simulation of a two-country model in which the real and financial sectors are integrated under an assumption of rational expectations and steady-state inflationary equilibria. The government of each country issues a single financial asset ("currency")...
