The role of environmental factors in growth accounting
使用方向性距离函数方法分析生产率增长，将二氧化碳等非期望产出纳入生产前沿，分解为效率变化和技术变化，并检验其统计显著性，对OECD和亚洲经济体的全要素生产率增长有启示。
Abstract This paper explores a relatively new methodology, the directional distance function method, to analyse productivity growth. The method allows us to explicitly evaluate the role that undesirable outputs of the economy, such as carbon dioxide and other greenhouse gases, have on the frontier production process which we specify as a piecewise linear and convex boundary function. We decompose productivity growth into efficiency change (catching up) and technology change (innovation). We test the statistical significance of the estimates using recently developed bootstrap methods. We also explore implications for growth of total factor productivity in the OECD and Asian economies.
