A Tale of Two Sectors: Why is Misallocation Higher in Services than in Manufacturing?
研究发现服务业资源错配程度显著高于制造业,若将服务业错配降至制造业水平,葡萄牙2008年总产出可提升约12%,增加值提升约31%,主要源于生产率冲击差异及服务业的价格刚性、劳动调整成本和非正规性。
Recent empirical studies document that the level of resource misallocation in the service sector is significantly higher than in the manufacturing sector. We quantify the importance of this difference and study its sources. Conservative estimates for Portugal in 2008 show that closing this gap, by reducing misallocation in the service sector to manufacturing levels, would boost aggregate gross output by around 12 percent and aggregate value added by around 31 percent. Differences in the effect and size of productivity shocks explain most of the gap in misallocation between manufacturing and services, while the remainder is explained by differences in firm productivity and age distributions. We interpret these results as stemming mainly from higher output‐price rigidity, higher labor adjustment costs and higher informality in the service sector.
