Real exchange rates are quite persistent. Standard unit root tests are not very powerful in drawing a conclusion regarding the validity of purchasing power parity [PPP]. Rather than asking if PPP holds throughout the whole sample period, we examine if PPP holds sometimes by employing...

While it is widely agreed that Purchasing Power Parity (PPP) holds as a long-run concept the specific dynamic driving the process is largely build upon a priori economic belief rather than a thorough statistical modeling procedure. The two prevailing time series models, i.e. the exponential...

In this paper we introduce a new nonlinear Markov-STAR model to capture both the markov switching and smooth transition dynamics for real exchange rates. The Markov switching part captures the effect of time variations of the equilibrium exchange rates, while the smooth transition part models...

This paper empirically assesses how democratization affects real exchange rates. By doing this, we combine so far separated strands of the economic literature and argue that democratization reduces currency undervaluation leading to a real exchange rate appreciation. We test this hypothesis...

Historical data for over hundred years and 14 countries is used to estimate the long-run effect of productivity on the real exchange rate. We find large variations in the productivity effect across four distinct monetary regimes in the sample period. Although the traditional Balassa-Samuelson...

This study analyzes the dynamics between real effective exchange rates and current accounts from a novel perspective. We start by dissecting long-run and time-varying short-run dynamics as well as causalities between both variables. Following this, we extend our framework by including short-term...

This study analyzes the dynamics between real effective exchange rates and current account patterns from a novel perspective. We start by dissecting long-run and time-varying short-run dynamics between both variables. Following this, we extend our framework by including interest rates into our...

In this paper we study the macroeconomic aftermath of large exchange rate appreciations. Using a sample of 128 countries over the period 1960-2008, we identify 25 episodes of large nominal and real appreciations shocks. We use narrative identification of exogenous appreciation episodes and study...

We explore the possible causal effect of economic policy uncertainty on the connectedness of crude oil and currency markets using a sample of commodity currencies from advanced and emerging nations. A battery of linear and nonlinear Granger-based causality tests indicate the presence of a causal...

This paper examines the effects of financial crises on the long memory volatility dependency of daily exchange returns focusing on the Asian crisis in 97-98 and the Global crisis in 08-09. By using the daily KRW-USD and JPY-USD exchange rates which have different trading regions and volumes,...
