This study provides new evidence of nonlinearities in the dynamics of volatility expectations during financial crises using Markov regime-switching models of model-free volatility indices. The regimes of changes in implied volatility in international financial markets are defined as function of...

Long-run income convergence is investigated in the US context. We employ a novel pair-wise econometric procedure based on a probabilistic definition of convergence. The time-series properties of all the possible regional income pairs are examined by means of unit root and non-cointegration tests...

Abstract This paper provides evidence that unemployment rates across US states are stationary and therefore behave according to the natural rate hypothesis. We provide new insights by considering the effect of key variables on the speed of adjustment associated with unemployment shocks. A...

This paper employs a pair-wise approach to examine regional integration in the US gasoline market. Using gasoline price data at the state level over a period of more than two decades, we find strong support for the view that the law of one price holds in regional markets, as more than 80% of...

The stationarity of OECD real exchange rates over the period 1972-2008 is tested using a panel of twenty six member countries. The methodology followed stems from the need to meet several key concerns: (i) the identification of which panel members are stationary; (ii) the presence of...

We examine the long-run relationship between remittances and the real exchange rate for less-developed countries. In a key departure from the literature, we employ a panel cointegration approach using an innovative method for the measurement of the multilateral real effective exchange rate and...

This article tests for stock market efficiency among 12 Asia-Pacific countries. A novel approach is applied where unit-root tests of real stock prices are embedded within a Markov regime-switching framework. Although standard univariate unit-root tests provide little support for stock price mean...

We explore the connection between the average propensity to consume (APC) and wealth to income ratio (WY) in the US. We find evidence of a long-run relationship characterised by threshold error correction. It is the APC that responds to long-run disequilibrium where the speed of adjustment is...

Existing panel data studies of real interest parity are either unable to identify which panel members are characterised by stationary real interest differentials, or are subject to size distortion resulting from the presence of structural breaks and cross-sectional dependencies. Using a panel...
