The Zudak paper (1976) restates in the Colombian context, without adding much that is new, some of the difficulties inherent in defining for practical applications the capital, labor, and output variables. He decides that the output-to-capital ratio in the case of Colombia is about .6 rather than .5 as suggested by Geithman and Landers in an earlier article in this journal (1973). Zudak concludes that the Colombian unemployment problem might best be managed by (1) improving the operation of the labor market, which Geithman-Landers advocated earlier, and (2) reducing the length of the work week. The latter suggestion, he apparently argues, is preferable to other possible policy responses to the employment situation recommended by Geithman-Landers. These consist primarily of (a) the development of additional labor-using production processes in the modern sector to expand the range of technical substitutability in that sector; (b) an active policy of income redistributton in the direction of greater equality in order to spur the demand for traditional sector output and dampen the demand for modern sector goods; and (c) a serious move toward land redistribution and reform as one available means of loosening the country's capital constraint.
