Native-American Camas Production and Trade in the Pacific Northwest and Northern Rocky Mountains

Traditional Native-American subsistence in the Pacific Northwest and northern Rocky Mountains followed annual cycles of fishing, hunting, and gathering. Camassia was the most widely used vegetable food. Camas bulbs were so highly regarded that native management strategies evolved to maintain their productivity and to prevent overexploitation. Tactics included control of access to tribally-held camas grounds, regulation of individual allocations of camas bulbs, private ownership of camas prairies, and application of quasi-agricultural practices toward increasing camas production.

Stable carbon isotope ratios and their relevance to the determination of accurate radiocarbon dates for lime mortars

Attempts have been made to date mortar by radiocarbon analysis. Potential problems are discussed, and the possible use of stable carbon isotopes to detect contamination by geological carbonates is investigated.     

GENERAL EQUILIBRIUM OF SPATIAL PRODUCT AND LABOR MARKETS*

ABSTRACT A simple general equilibrium model relates spatial product markets and spatial labor markets. The firm is treated as being a spatial monopolist or as a Löschian competitor in the output market and as a spatial monopsonist in the labor market. Derived free spatial demand and free regional labor supply are defined, and their properties examined. The model provides the framework for analyzing the impact of a technological improvement in labor productivity on the structure of the spatial markets. The impact of entry on spatial labor supply is an important determinant of whether or not entry lowers wages and raises output prices. Unlike the spaceless competitive paradigm, zero-profit long-run equilibrium can occur in a space economy under conditions of increasing returns to scale.
