This paper examines spatial integration of food grain markets in India. Using the maximum likelihood method of cointegration, it investigates whether regional food grain markets within and across states are spatially linked or not. The cointegration tests provide evidence in favour of spatial...

This paper examines the random walk hypothesis in the Visegrad Countries stock market as emerging stock markets. The results both from autocorrelation analysis and unit root tests imply that monthly stock price indices of the Visegrad Countries follow the random walk process. This means that the...

This paper empirically examines the long-run pass through of the official exchange rates into trade balance in Nigeria by means of threshold cointegration and asymmetric error correction modeling. The study provides evidence for non-linear cointegration between our variables of interest. The...

The objective of this paper is to evaluate the behaviour of Nigerian Stock Exchange (NSE) sector indices. Specifically, the paper analyzes the returns correlation, serial correlation and heteroscedasticity on the NSE All-share Index, Banking Index, Consumer Goods Index, Oil & Gas Index, NSE 30...

This study examines nonlinear adjustment effects in the purchasing power parity (PPP) between South Africa and her main currency trading partners; namely, the US, the UK, the Euro area, China and Japan. We use monthly data of the nominal exchange rates and domestic price level data collected...

Standard autocorrelation corrections applied to cointegrating regressions can lead to erroneous first-differencing. Such outcomes are shown to be possible under a range of environments, including cases with autocorrelation coefficients substantially less than 1. First-differencing of a...

When dealing with time series that are integrated of order one, the concept of cointegration becomes crucial for the specification of a model. Using the best available tests, one can reduce the probability of estimating econometric models that are misspecified. This paper investigates the small...

In this note we establish the existence of the first two moments of the asymptotic trace statistic, which appears as weak limit of the likelihood ratio statistic for testing the cointe- gration rank in a vector autoregressive model and whose moments may be used to develop panel cointegration...

This paper shows that the integrated modified OLS (IM-OLS) estimator developed for cointegrating linear regressions in Vogelsang and Wagner (2014a) can be straightforwardly extended to cointegrating multivariate polynomial regressions. These are regression models that include as explanatory...
