Poor economic performance in a country will often lead to changes in the do
mestic policies and institutions, political instability, or changes in inte
rnational relations. Induced institutional change of this kind affects the
interpretation of the empirical evidence on economic convergence: a diverge
nt process may be stabilized by institutional and political intervention. S
tabilization may result even if the effects of each intervention are stocha
stic and the expected value of the benefits from each reform is non-positiv
e. Thus, the appearance of conditional convergence may carry no implication
s for 'the underlying parameters of technology and preferences.' (C) 1999 E
