Stability tests for cointegrating coefficients are known to have very low power with small to medium sample sizes. In this paper we propose to solve this problem by extending the tests to dependent cointegrated panels through the stationary bootstrap. Simulation evidence shows that the proposed...

We address the issue of estimation and inference in dependent non-stationary panels of small cross-section dimensions. The main conclusion is that the best results are obtained applying bootstrap inference to single-equation estimators, such as FM-OLS and DOLS. SUR estimators perform badly, or...

In this paper we test for the existence of a long-run relationship between investment and savings (the Feldstein–Horioka puzzle) in a panel of 18 OECD countries, 1970–2007, allowing for heterogenous breaks in the coefficients. For this purpose we develop a bootstrap panel cointegration with...

In this paper we test for the existence of a stable long-run savings–investments relationship in 18 OECD economies over the period 1970–2007. Although individual modelling provides only very weak support to the hypothesis of a link between savings and investments, this cannot be ruled out as...
