An econometric analysis of output supply and input demand in the Canadian softwood lumber industry

Creator:: Latta, Gregory S. and Adams, Darius M.
Abstract:: Few studies have examined the own-price elasticity of Canadian softwood lumber supply or output-adjusted factor demand elasticities over the past two decades, despite the utility of these measures in understanding producer response to tariffs, to market shifts (such as the decline in U.S. public harvest), and to changes in domestic...
