It would also be interesting to examine the evolution of these linkages over time. The values of [N—N*] in 1980, 1985 and 1990 (all in 1985 constant prices) are illustrated in Fig. 4. Clearly, variations in estimates of [N—N*] over time will depend on changes in the price (specifically the relevant rental rates), as well as changes in the quantity of resources traded. The OECD and Middle East and North Africa (MENA) dominate the overall picture. Fig. 4 shows that in terms of the dollar value of [N—N*], consumption of global resources by the OECD decreased significantly in 1985 with little change in 1990 (relative to 1985). The mirror image of this is the experience of Middle East and North Africa. It is likely that these results reflect, to a large extent, changes in the international price of resources and in particular oil. World Bank (2000) indicates that the world price of oil in 1985 was 42% lower than in 1980. Prices for several of the mineral resources covered in our data on resource depletion also were considerably lower in 1985 than in 1980. Hence, this general downward trend over the period between 1980 and 1985 is also exhibited (albeit less pronounced) in SSA and East Asia (EASIA). By contrast, a similar trend to that prevailing in the OECD is experienced in South Asia (SASIA) and Eastern Europe (EEUR).
