Data Descr iption Labor. The labor quantity and pr ice ser ies for both the U.S. and Japan are an amalgamation of series constructed . '",~ by the Bureau of'Labor Statistics cover ing var ious per iods of time. l/ As pointed out above, the BLS makes some limited corrections in its ser ies to reflect product mix differentials and the ser ies developed here reflects these corrections. .l-. . Iron Ore. For the United States, the source of the iron ore quantity series was the total iron ore consumption reported by the American Iron and Steel Institute (AISI) (1). The price' of iron ore used for the United States was a ~eighted average of prices computed for domestic and imported ore. For domestic ore, the pr ice used was - the aver age val ue a t the mine of usable iron ore- mined in the U.S. reported by the Department of the Interior, Bureau of Mines (42)
. To the value of ore at the mine was added an estimated cost of transportation to the steel mill. The estimate was based on transportation rates published periodically in Skilling's_Mining Review. The estimated time series of transportation costs is shown in appendix (, 3A. For imported ore, the quantity and value were obtained from the Department of the Interior (42). Since the values given are f.o.b. the exporting country, a transportation cost 3/ Along with unpublished BLS òata covering the period 1964 to I974, data were used from Jackman (9) and Mark (23). The data from Mark incorporated changes suppl ied to us by the Bureau of Labor Statistics through May 1977. The 1976 figures are projections based on datal in (l), (111, and (l2). -102- was added, estiffated on the basis of data obtained from major U.S. steelmakers through compulsory questionnaires. For Japan, the quantity of iron ore used was the sum of annual "imported" and "home iron ore consumption in the iron and steel inõustry" reported by Japan Iron and steel Federation (JISF) (12). The price of iron ore used for Japan was the annual average c.i.f. price of imported iron ore from the JISF (15) .
.'. . Scrap. Only scrap purchased from outside the steel mills (as opposed to that generated internally) was considered in calculating the cost of scrap. i/ If internally generated scrap had been included, there would be double counting since the cost of materials, energy, and labor used to produce that scrap are included in other cost ser ies. For the U.S., the quantity of scrap purchased was computed from data reported by the AISI (1) simply by subtracting the quantity of scrap "produced" from that "consumed." The price used for U.S. scrap was the annual average, composite price of ll heavy melting scrap at Chicago, Philadelphia, and Pittsburgh from Iron Age. For Japan, the quantity of scrap purchased was obtained from the JISF (12) and (13). Separate figures were available for the quantity imported and the quantity purchased in Japan. 4/ Data on the total consumption of scrap are shown in appendix 3A. -103- The pr ice used for domestically purchased scrap was the domestic "market" pr ice and for imported scrap the "average" cost of imports, c.i.f., both as reported by the JISF (15)
. Coking Coal. The quantity of coking coal consumed by the U.S. steel industry was obtained from the AISI (1). The price used was annual "average cost of coking coal at merchant coke ovens" from Department of the Interior data (42). This value included the cost of transportation to the, ovens. Coking coal consumption by the Japanese steel industry was obtained from the JISF (12). The pr ice usee for Japan was the average cost ~f imports, c.i.f., from the JISF (15). Non-Coking Coal. For the U.S. industry, the quantity of non-coking coal was obtained from the AISI (1) by subtracting "coal consumed in product ion of coke" from W totalW coal consumption. The price for non-coking coal was estimated, using data from the Department of the Inter ior (42). The average f .o.b. mine value in the U.S., reported in (42J for bituminous and lignite coal, was adjusted downward by taking tnto account the quantity and value of that coal which was sold as coking coal. To arrive at a delivered price, the authors added to the adjusted f.o.b. value the average railroad freight charge for sh ipmen ts of cok ing coal to merchant ovens, which also appear s in (42J.
