Structural Change, Expanding Informality and Labor Productivity Growth in Russia
研究了俄罗斯1995-2012年间34个行业的结构变化对劳动生产率增长的影响，发现结构变化整体促进增长但效应随时间减弱，劳动力从正规部门流向非正规部门会因低生产率活动扩张而拖累增长。
Strong growth, intensive structural change, and expanding informality have characterized many developing and emerging economies in recent decades. Yet most empirical investigations into the relationship between structural change and productivity growth overlook informality. This paper includes the informal sector in an analysis of the effects of structural changes in the Russian economy on aggregate labor productivity growth. Using a newly developed dataset for 34 industries covering the period 1995–2012 and applying three alternative approaches, aggregate labor productivity growth is decomposed into intra‐industry and inter‐industry contributions. All three approaches show that the overall contribution of structural change is growth enhancing, significant, and decreasing over time. Labor reallocation from the formal sector to the informal sector tends to reduce growth through the extension of informal activities with low productivity levels. Sectoral labor reallocation effects are found to be highly sensitive to the methods applied.
