In this note, we examine the size and power properties and the break date estimation accuracy of the Lee and Strazicich (LS, 2003) two break endogenous unit root test, based on two different break date selection methods: minimising the test statistic and minimising the sum of squared residuals...

Structural breaks in relationships between macroeconomic and financial time series are likely a result of financial crises or local reforms. If such structural breaks exist, cointegration tests have to take them into account. Arai and Kurozumi (2007), Carrion-i-Silvestre and Sanso (2006) and...

Our study analyses stochastic convergence of relative real GDP per capita in the West African Economic and Monetary Union (WAEMU) in the period 1960 to 2010. It highlights the importance of considering structural breaks and cross-section dependence in the panel unit root tests. Using the panel...

This paper examines the interaction between financial development and economic growth of the Economic Community Of West African States (ECOWAS) and West African Economic and Monetary Union (WAEMU) using non-stationary panel data methodology and a panel cointegration approach. We estimate a...

Buiter (1981) illustrates that in the OLG model, the ranking of stationary utility levels under autarky and openness, is ambiguous. We show that both countries increase their stationary utility levels only if the autarky capital-labor ratios are on opposite sides of the golden rule.

This paper shows that there is the weak “Globally” Ricardian rules that sustains the sustainability of the government debt in the sense that it binds intertemporal government budget constraint. And we compare our result with the former paper about testing the government debt sustainability....
