Although the overall average rate of growth in the world economy during this quarEer century was relatively qood by previous standards, there was. a disturbing tendency for i! to decelerate vrith the passage of time. The 1960s represented a decade of relatively steady and high grorrth in the r,ror ld economy, wich world output grorring on average more than 5 per cent a year. During the first Development Decade, despite the handicaps of poverty and the narrow expor! base of the developing market economies, the GDP of those econonies as a whole grew at a significantly bigher rate than in the developed market economies as a whole. As the 1960s came to an end, hosever, the rate of increase in rdorld production was falling from the peak recorded earl,ier in the decade. The 1970s, in contrast, were characterized by generally slow growth in nost world regions and unparalleled instability in the developed market economies. Following rapid growth during the first three years of che second Development Decade, severe fluctuations in the business cycle were recorded, one of them the steepest and deepest recession since the 1930s. When growth fattered in the developed market economies, the slowdown was transmitted directly to the develoPing economies by means of the strong export orientation of the latter to the former. The insLability in the developed market economies was also coupled with a virulenl inflation and hlgh unemployment levels
