The educated lavman, for whom this book is intended, will find the author's leaps from the level of the quoted material into sophisticated physical chemistry and back ...

Labor Surplus Economies

The labor surplus economy model has as its basic premise the inability of unskilled agricultural labor markets to clear in countries with high man/land ratios. In such situations, the marginal product of labor is likely to fall below a bargaining wage, related to the average rather than the marginal product.

This paper demonstrates that the economic surplus which agents produce in bilateral interactions is extractable by an outside party having sufficient initial resources. The third party achieves this outcome using a class of ‘‘exclusive-interaction’’ contracts. A basic extractability result is shown to be robust to several extensions: competition among outside parties, multiplicity of interactin...
