[Puzzle 1: Was Judge Hand correct in his celebrated judicial opinion that Alcoa's monopoly in "virgin" aluminum provided indirect control over "secondary" production? Answer: Estimates based on three models suggest that the "procompetitive" effect of recycling was largely offset by a reduction in virgin production in anticipation of future conversion into secondary. Thus, Hand's judgment appears sound. Puzzle 2: Is it in Alcoa's own interests to suppress recycling of scrap aluminum if feasible? Answer: If current users show that they value the future use of the product by selling scrap to merchants, then Alcoa is likely to value the recycling market also. If users discard scrap which is subsequently scavenged, then Alcoa is likely to be harmed by such activity.]

[Understanding of the relationship between producer choice of product qualities and consumer preferences has been enhanced by the development of models specialized to a particular quality attribute--durability. Durability choice is invariant with respect to market structure under certain conditions but capital market imperfections and income taxes can upset this strong independence result. Income taxes are shown to mimic the effect of a capital market distortion on a monopolist selling a durable. Moreover, contrary to previous results the tax can increase as well as lower durability. A tax on "true income" is neutral in its effect and hence tax reform provides an alternative to regulatory control of product life.]
