We consider cointegration rank estimation for a p-dimensional Fractional Vector Error Correction Model. We propose a … levels. The first step consists in estimating the parameters of the model under the null hypothesis of the cointegration rank … r=1,2,...,p-1. This step provides consistent estimates of the order of fractional cointegration, the cointegration …

We consider VAR models for variables exhibiting cointegration and common cyclical features. While the presence of … cointegration reduces the rank of the long-run multiplier matrix, other types of common features lead to rank reduction of the short …

There are simple well-known conditions for the validity of regression and correlation as statistical tools. We analyse by examples the effect of nonstationarity on inference using these methods and compare them to model based inference using the cointegrated vector autoregressive model. Finally...

Maize is a major staple food in Sub-Saharan Africa. Monthly maize prices in Tanzania are analyzed since the country is an important maize producer and exporter in East Africa. We analyze price transmission between the five most important urban regions of Tanzania between 2000 and 2008 which...

We assess market integration and price transmission of perishable agricultural produce in Sub-Saharan Africa by studying Ghanaian tomato markets which are characterized by pronounced seasonality in production and trade flows. We analyse the tomato markets of Ghana by simultaneously regarding its...

We consider cointegration tests in the situation where the cointegration rank is deficient. This situation is of … interest in finite sample analysis and in relation to recent work on identification robust cointegration inference. We derive … asymptotic theory for tests for cointegration rank and for hypotheses on the cointegrating vectors. The limiting distributions …
