Effects of increasing agricultural productivity in a multisectoral model for the Philippines
基于一般均衡框架，量化分析菲律宾农业生产力提升对农村与城市家庭收入、贸易平衡及国民收入的差异化影响，发现食品加工业生产力提升对农业和农村收入有显著正向联动效应。
This paper investigates empirically the economy-wide effects of agricultural productivity increases in the Philippines, reporting the results of a quantitative analysis based on a general equilibrium framework. A multisectoral, price endogenous model of the Philippine economy is employed, emphasizing not only agriculture but also other production sectors with which it closely interacts, as well as the distinction between rural and urban households in their income generation and consumption patterns. Among other findings, the differential effects on the real income of rural households vis-a-vis urban households arising from increased productivity in the various components of the agricultural production sector are striking. The resulting improvements in the trade balance and national income, among other macroeconomic variables, are also relatively significant. Moreover, there are significant differences in the economy-wide effects among the four sectors of food and agriculture distinguished in the study. Particularly interesting is the highly favorable impact of rising productivity in the food processing sector on agricultural crop production and rural income, a linkage effect that has not received much attention in the development literature.
