Bridging the Gap between Partial and Total Factor Productivity Measures Using Directional Distance Functions
提出一种无需跨部门分配所有投入的部门生产率测量方法，应用于多国农业部门，发现畜牧业和作物生产率增长存在显著差异，且常用部分要素生产率指标在发展中国家高估、在欧洲国家低估生产率增长。
Technical dependencies as well as data constraints limit our ability to allocate inputs across sectors and hence our ability to measure sectoral productivity. We adapt a directional measure of efficiency to the measurement of sector‐specific productivity that does not require allocating all inputs across sectors. Applied to the agricultural sector of a group of countries, the results show important differences in livestock and crops productivity growth. Commonly used partial factor productivity measures for livestock and crops tend to overestimate productivity growth in most developing countries while underestimating it in European countries.
