This paper reviews a class of multifractal models obtained via products of exponential Ornstein–Uhlenbeck processes driven by Lévy motion. Given a self-decomposable distribution, conditions for constructing multifractal scenarios and general formulas for their Renyi functions are provided....

Tests for long‐run macroeconomic convergence among European Union (EU) countries according to the various exchange rate regimes that have prevailed over the last 40 years. Applying a recently developed test to the monthly index of industrial production data, output convergence is confirmed or...

Following Clarida and Taylor, the term structure of forward exchange premiums can be interpreted as multiple cointegration vectors, if it is assumed that departures from the risk‐neutral efficient markets hypothesis are stationary. This hypothesis is tested using spot rates and one‐month and...

This paper examines the existence and stability of both the long‐ and short‐run demand for narrow and broad money balances. The data for Singapore are used as a case study. The quarterly period examined is 1973:2‐1999:3 (105 observations). The study reveals the existence of a systematic...

A non‐structural model is used to analyze the dynamic effects of fiscal and exchange rate policies on Ghana's economy. In particular, the paper sheds light on how these two key structural adjustment policy variables affect the short‐run and long‐run dynamics of inflation, output and...

Productivity bias hypothesis claims that deviation of the PPP based exchange rate from the equilibrium rate is mainly due to productivity differentials among countries. Early studies that employed cross‐sectional data in testing the hypothesis provided mixed results. A few time‐series...

This paper examines and dissects eight popular conjectures about exchange rates. The conjectures are: there exists a systematic linkage between economic fundamentals and exchange rates; flexible exchange rates are unstable due to destabilising speculation; flexible exchange rates are excessively...

Purpose – Since the last review article by McKenzie, the literature has experienced a surge in the number of empirical articles. These new contributions, coupled with those that were overlooked by McKenzie, set the stage for this review. Many of the recent studies have been empirical in nature...

Purpose – In what seems as an infinitely ongoing debate regarding the purchasing power parity (PPP) theory, this paper seeks to question the strength of the scientific “evidence” put forward by the PPP revisionists Design/methodology/approach – In this paper, the validity of the PPP...
