This paper reviews panel unit root and cointegration tests in the context of PPP. It highlights various drawbacks of existing methods. First, unit root tests suffer from severe size distortions in the presence of negative moving average errors. Second, the common demeaning procedure to correct for the bias resulting from homogeneous cross-sectional dependence is not effective; more worryingly, ...

This paper uses the extreme bounds analysis (EBA) of Leamer (1983 &1985) to analyze the robust determinants of the demand for money in a panel of 17 Asian countries for the period 1970 to 2009. These robust determinants are found to be unit root variables. Therefore, cointegration between these variables is tested with a recent time series panel method developed by Westerlund (2007). This metho...

The authors examine the link between consumption and disaggregate wealth in Canada. They use a vector-error-correction model in which permanent and transitory shocks are identified using the restrictions implied by cointegration proposed by King, Plosser, Stock, and Watson (1991) and Gonzalo and Granger (1995). This procedure allows the authors to identify the reaction of consumption to both ty...

Time series cointegration tests, even in the presence of large sample sizes, often yield conflicting conclusions (“mixed signals”) as measured by, inter alia, a low correlation of empirical p-values [see Gregory et al., 2004, Journal of Applied Econometrics]. Using their methodology, we present evidence suggesting that the problem of mixed signals persists for popular panel cointegration tests....

The European sovereign debt crisis revived the discussion concerning pros and cons of exchange rate adjustment in the face of asymmetric shocks. In the spirit of Keynes, exit from the euro area is to regain rapidly international competitiveness. In the spirit of Schumpeter, exchange rate stability with structural reforms would be beneficial towards the long-run growth performance. Previous lite...

An IV approach, using as instruments nonlinear transformations of the lagged levels, is explored to test for unit roots in panels with general dependency and heterogeneity across cross-sectional units. We allow not only for the cross-sectional dependencies of innovations, but also for the presence of cointegration across cross-sectional levels. Unbalanced panels and panels with differing indivi...

This paper focuses on the macroeconomic management of large inflows of foreign aid. It investigates the extent to which African countries have coordinated fiscal and macroeconomic responses to aid surges. In practice, we construct a panel dataset to investigate the level of aid ‘absorption’ and ‘spending’. This paper departs from the recent empirical literature by utilising better measures for ...

The real exchange rate (RER) misalignment is a key variable in academic and policy circles. Among policy circles, sustained RER overvaluations are observed by authorities for future exchange rate adjustments. Some countries, on the other hand, have pursued very active exchange rate policies in order to undervalue their currencies to foster growth through export promotion (e.g. China). Our goal ...

A number of studies have estimated the income elasticity of health care expenditure to identify whether health care is a necessary or luxury product. However, the issue has received less attention in developing countries, especially in Asian economies. The current study for the first time has used the panel data covering 36 Asian countries for the period 1995-2013 for revealing the nature of he...
