Productivity Growth in U.S. Agriculture under Dynamic Adjustment
在调整成本框架下建立了一个动态生产率增长测度，用于修正长期均衡偏离。应用于美国农业，发现技术变革主导全要素生产率增长，而规模、质量调整投入和长期非均衡投入的贡献仅占3.44%。
Abstract A dynamic measure of productivity growth adjusted for deviations from the long‐run equilibrium is established within an adjustment‐cost framework. An empirical application to U.S. agriculture is presented which permits identifying the dynamic linkages between technical change and productivity growth in U.S. agriculture. Total factor productivity as dynamically measured grew at 1.50% per annum. The combined effect of scale, quality‐adjusted input growth, and long‐run disequilibrium input use contributes only 3.44% of the growth, while technical change dominates the growth of total factor productivity.
