Abstract

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 individual time series tests may have low power. We thus construct a new bootstrap test for panel cointegration robust to short- and long-run dependence across units. This test provides evidence of a long-run savings–investments relationship in most of the countries, with USA the most notable exception. However, the elasticities generally smaller than 1 suggest that market imperfections mostly cause only partial home biases. Copyright Springer-Verlag Berlin Heidelberg 2014
