Food subsidies and market interdependence: The case of the Moroccan soft wheat subsidy
研究了摩洛哥软质小麦补贴成本上升的原因，通过三部门供需模型分析发现间接效应主要来自软质小麦市场本身，而非相关市场。
Among the several propositions advanced to explain the rising cost of subsidizing soft wheat production and consumption in Morocco are the indirect effects emanating from related markets, namely the hard wheat and barley markets. A three-sector supply-demand model, described in this paper, was used to estimate the direct and indirect (induced) effects on government cost of changes in the soft wheat subsidy. The results show that virtually all the indirect effects come from the soft wheat market itself. The indirect effects emanating from the related markets are negligible.
