This paper investigates the determinants of real interest rates at world and country level. The starting point is the idea that the real interest rates reflect the interaction of desired saving and planned investment, using the framework developed by Barro and Sala-i- Martin (1990) and Barro (1992).

This paper uses a unique panel data at the level bargaining group to examine aspects of 'right-to manage' models of wage determination. Empirical measures of firms' and unions' bargaining power are identified and found to be important influences on wage setting.

In this paper we assess, via Monte Carlo Simulations, the effects of some seasonal adjustment linear filters on cointegrating regressions. We find that the use of filters has adverse consequences in terms of the power of the Augmented Dickey and Fuller and Phillips and Perron tests of cointegration.
