标题:Positioning for Trade Liberalization: Structure of Earnings, Comparative and Competitive Advantage of Agricultural Households in the United States and Canada
摘要:Change in the earnings structure of agricultural households in North America is an important concern of policy makers in Canada and the United States. Earnings structure reveals the strengths and weaknesses of households in the climate of policy change, competition and predation associated with trade liberalization. Earnings structure can be broken down into source and composition structures. The source structure of earnings contains information about where household income is derived: market income, off-farm income, direct agricultural subsidies, social safety nets, and other income. The composition structure of earnings expresses returns in terms of wages, capital, and rents according to the form of property right underlying production.
