In this paper we use a Threshold AutoRegressive (TAR) model to capture the nonlinear dynamics of monthly real effective exchange rate data for the G7 countries. The novelty of our approach relates to the use of the real interest differential as the switching variable. This choice allows us to...

The main objective of this paper is to test the validity of the purchasing power parity in the Maghreb countries (namely, Algeria, Morocco and Tunisia). We apply the threshold autoregressive non-linear model (TAR) proposed by Caner and Hansen (2001). First, a review of literature on PPP is...

This paper analyses the out-of-sample forecasting performance of non-linear vs. linear models for the South African Rand against the United States dollar and the British Pound, in real terms. We compare the forecasting performance of point, interval and density forecasts for non-linear Band- TAR...

The efficient market hypothesis (EMH), which suggests that returns of a stock market are unpredictable from historical price changes, is satisfied when stock prices are characterized by a random walk (unit root) process. A finding of unit root implies that stock returns cannot be predicted. This...

Performance indices for illiquid investments are known to suffer from returns smoothing, and the purpose of this paper is to investigate the presence and nature of such smoothing in the context of venture capital. We find that while the standard techniques may or may not indicate the presence of...
