Quasi-Cores in a Monetary Economy with Nonconvex Preferences

Econometrica 1966 34(4), 805
A model of a pure exchange economy is investigated without the usual assumption of convex preference sets for the participating traders. The concept of core, taken from the theory of games, is applied to show that if there are sufficiently many participants, the economy as a whole will possess a solution that is sociologically stable--i.e., that cannot profitably be upset by any coalition of traders.

Multiple Product Costing by Multiple Correlation Analysis.

The Accounting Review 1966 41(4), 673-680
The article focuses on the application of multiple correlation analysis in multiple product costing. The allocation of costs assumes that the products should receive costs relative to the benefits that the products received from the production process. The authors conclude that multiple correlation analysis frees the accountant from making the assumption that marginal costs per product are always too difficult to unearth. For products that have an output proportion that is variable, multiple correlation allocates costs in a method valuable for decision-making.
