Market power in economic theory is defined as deviations from marginal cost pricing, which results in unfair competition and welfare losses. In complex agri-food supply chains, the exercise of market power is a significant contributor to welfare losses, as multiple actors throughout the chain...

We propose a residual-based augmented Dickey-Fuller (ADF) test statistic that allows for detection of stationary cointegration within a system that may contain both I (2) and I (1) observables. The test is also consistent under the alternative of multicointegration, where first differences of...

We propose a residual-based augmented Dickey–Fuller (ADF) test statistic that allows for detection of stationary cointegration within a system that may contain both I(2) and I(1) observables. The test is also consistent under the alternative of multicointegration, where first differences of...

Previous empirical studies on the Fisher hypothesis have focused on developed countries, thus leaving developing countries with no or very few studies. This paper tests the validity of the hypothesis for six Asian countries over the period 1978-2005 using a cointegration procedure developed by...

We propose two new simple residual-based panel data tests for the null of no cointegration. The tests are simple because they do not require any correction for the temporal dependencies of the data. Yet they are able to accommodate individual specific short-run dynamics, individual specific...
