We consider a class of panel tests of the null hypothesis of no cointegration and cointegration. All tests under investigation rely on single-equations estimated by least squares, and they may be residual-based or not. We focus on test statistics computed from regressions with intercept only...

In this paper we show the consequences of applying a panel unit root test when testing for a purchasing power parity relationship. The distribution of the tests investigated, including the IPS test of Im et al (1997), are influenced by a common stochastic trend which is usually not accounted...

This paper attempts to make an innovative contribution to the growth literature by proposing a trade-induced catch up model in which imitation benefit is explicitly modelled and trade knowledge spillover is considered. The resulting income dynamics is in the error correction form. The Pooled...

This paper analyses the impact of the reduction of tariff and non-tariff barriers on the trade balance and the current account of the balance of payments of 22 selected developing countries from Africa, Latin America, East Asia, and South Asia. The study presents estimates of dynamic panel data...

Empirical studies on aggregate export behaviour have recently emphasised the role played by innovation as the main force driving product differentiation and competitiveness for developed countries. These studies treat foreign innovation as a variable that affects negatively national export...

This paper analyses the impact of the reduction of tariff and non-tariff barriers on the imports of selected developing countries, utilising dynamic panel data techniques. Domestic income and relative prices are found to be significant determinants of import growth. Additionally, the results...

This paper examines the pattern of employment adjustment in Portugal. First, the issue is addressed using a long time series of aggregate data. Although the employment data show persistence, there is nonetheless a fairly rapid rate of employment adjustment. Second, a much shorter time series of...

The three-step generalized methods of moments (GMM) approach of Kapoor, Kelejian and Prucha (2007), which corrects for spatially correlated errors in static panel data models, is extended by introducing fixed effects, a spatial lag, and a one-period lag of the dependent variable as additional...

Advertising pre-testing (or copy testing) is often employed in sales forecasting. It helps to quantify the impact of advertising on generating awareness, trial and repeat purchases. This paper reviews existing copy testing practices and makes some practical recommendations in the context of...
