The paper examines convergence on the European level by using production fu
nctions which include capital and labor as factors of production. The metho
dology is based on principal-components analysis of common trends appropria
te for heterogeneous panels. Using data for the 1960-1997 period and altern
ative specifications, it is found that convergence can be decisively reject
ed, although the number of common trends is relatively low (about four or f
ive).
