Nonlinear models of deviations from PPP have recently provided an important, theoretically well motivated, contribution to the PPP puzzle. Most of these studies use temporally aggregated data to empirically estimate the nonlinear models. As noted by Taylor (2001), if the true DGP is nonlinear,...

We adapt the Casselian version of purchasing power parity to a two-period framework. In this framework, we show that inter-temporal trade plays a role and can drive a wedge betweenthe nominal exchange rate and relative prices. The size of trade flows, the real interest rate, and the constraint...

Purchasing power parity (PPP) is a useful tool for international comparison of prices between countries, in order to analyze the degree of economic development. On this line, purchasing power parities are indicators that express the main macroeconomic aggregates, in a common currency for all the...

We estimate a unified measure of inclusive growth for emerging markets by integrating their economic growth performance and income distribution outcomes, using data over three decades. Country distributions are calibrated by combining PPP GDP per capita and income distribution from survey data....

This is the sixth of a series of papers that are being written as part of a project to estimate a small quarterly Global Projection Model (GPM). The GPM project is designed to improve the toolkit to which economists have access for studying both own-country and cross-country linkages. In this...

This Selected Issues paper describes the monetary transmission mechanism in Sierra Leone. The paper uses a vector autoregression model to explore the links between policy changes by The Bank of Sierra Leone and real variables, such as output and prices. The paper describes Sierra Leone’s...

Most economists intuitively consider purchasing power parity (PPP) to be true. Nevertheless, quite surprisingly, the empirical literature is not very supportive for PPP. In this paper, however, we find evidence in favor of PPP using a new test. The test is embedded in a Markov regime-switching...

We use the Johansen cointegration approach to assess the empirical validity of the purchasing power parity (PPP) between the UK and the Euro Area, which we represent by Germany, the largest of its members. We conduct the empirical analysis in the context of the global financial crisis that began...

The half-life of deviations from purchasing power parity (PPP) plays a central role in the ongoing debate about the ability of macroeconomic models to account for the time series behaviour of the real exchange rate. The main contribution of this paper is a general framework in which alternative...

This paper formulates an optimizing model of a small open economywith a representative (immortal) household, a firm and agovernment. The asset menu consists of domestic currency,non-traded bonds and traded bonds. There is a risk-premium ontraded bonds, which leads to deviations from perfect...
