TECHNICAL CHANGE AND EC‐US AGRICULTURAL TRADE LIBERALISATION
研究了在评估欧美农业政策部分自由化效果时，忽略技术变革会导致偏差，并指出考虑技术变革会改变农场收入与预算支出的权衡，影响政策工具效果，甚至可能逆转贸易效应。
The paper aims to investigate the biases produced by assessing the effects of partial liberalisation of EC and US farm policies through comparative‐static simulations, when a more adequate approach would require time, or more precisely technical change, to be explicitly accounted for. Three points are underlined: taking into account technical change (i) alters the trade‐off between farm income and budgetary expenditures, (ii) has different effects according to the policy instruments used, and (iii) may reverse the sign of cross‐effects, particularly on the budget, in the case of large price‐support reductions which result in trade reversal. The relatively limited fall in farm income losses in scenarios corresponding to full harmonisation makes the associated support‐price cuts more acceptable, both politically and socially.
