We consider the single item lot-sizing problem with capacities that are non-decreasing overtime. When the cost function is i) non-speculative or Wagner-Whitin (for instance, constantunit production costs and non-negative unit holding costs), and ii) the production set-upcosts are non-increasing...

To date, empirical investigations of trade liberalization under the conditions of increasingreturns to scale (IRS) and imperfect competition (IC) have either assumed or imposed themarket and productive structures necessary for such a model. However, of the recent IRS/ICmodels used to simulate...

Using U.S. manufacturing data, Griliches (1969) found evidence suggesting that capitalequipment was more substitutable for unskilled than skilled labor. Griliches formulated thisfinding as the capital-skill complementarity hypothesis. The purpose of this study is todetermine whether the...
