The purpose of this paper is to examine the issue of omitted variables in testing the long run validity of Wagner's hypothesis. Using UK data for the period 1948 to 1997, this paper first investigates the secular relationship between public spending and economic development in a bivariate...

This paper presents exogeneity tests for the existence (or absence) of a behavioural relationship between financial deepening and economic growth for three high performing economies: Hong Kong, South Korea and Taiwan. The findings suggest that weak, strong and super exogeneity assumptions are...

This article investigates the impact of openness and tariff reductions on the technical inventiveness of selected OECD countries. The results suggest that even these simple forms of trade liberalization may, under certain conditions, favour technical inventiveness or creativity, the most...

Tests based on normalized autocorrelation coefficients have been commonly used by applied researchers to examine the randomness of economic and financial time series. This paper investigates via Monte Carlo simulation the finite-sample properties of these tests for randomness, paying special...
