“…Empirical research on this topic is heavily concentrated on data from the mid-and late fifties with some extensions into the 1960s. While this problem has been one of the most heavily researched in quantitative international politics (Rummel, 1963;Haas, 1965;Tanter, 1966;Wilkenfeld, 1968Wilkenfeld, , 1969Wilkenfeld, , 1972Flanigan andFogelman, 1970: Burrowes andSpector, 1973;Collins, 1973;Hazlewood, 1973Hazlewood, , 1975Liao, 1976: Eberwein et al, 1978summaries in McGowan and Shapiro, 1973;Zinnes, 1975;Zimmermann, 1975Zimmermann, , 1976), clarity has not yet been achieved. There seems to be no significant relationship over all nations during the 1950s (Rummel, 1963;Tanter, 1966), but there tnight be at least a spurious ohe for the midsixties (Eberwein et al, 1978).…”
