An econometric model of hardwood lumber and stumpage markets in the United States

Creator:: Lange, William J.
Abstract:: Two econometric models were developed to forecast consumption, production, and price of hardwood lumber, and removals and price of hardwood sawlog stumpage. Four eastern U.S. regions were represented in the models. Hardwood lumber consumption by manufacturing, shipping, residential construction, and nonresidential construction industries was recognized. Hardwood sawlog stumpage removals from...

The effects of factor supply assumptions on intertemporal timber supply behavior: the cases of investable funds and land

Creator:: Adams, Darius M., Alig, Ralph J., McCarl, Bruce A., Winnett, Steven M., and Callaway, J.M.
Abstract:: Intertemporal timber supply models typically assume perfect capital markets and perfectly inelastic supplies of land. Using a dynamic model of U.S. timber and agriculture markets, we examine (i) borrowing limits or capital constraints, in which investment in forest management on nonindustrial private ownerships is restricted, and (ii) a nonzero elasticity...
