Cointegration of U.S. budget and current account deficits: Twins or strangers?

In this paper the authors employ the cointegration approach to explore empirically the existence of a possible long-run equilibrium relationship between the U.S. budget deficits and the current account deficits. This study uses annual nominal data in levels for the postwar period 1946–1988. Both the DW and the ADF tests confirm that the two deficits are not cointegrated. It implies that the two deficits have no possibility of reverting to a long-run equilibrium relation.
