The effects of supporting local business: Evidence from the UK
利用英国贫困地区的企业扶持政策数据，通过断点回归发现该政策未增加本地就业，反而导致邻近地区约10%的就业被挤走，说明此类政策可能因间接挤占效应而难以缩小经济不平等。
This paper assesses the effects of a significant place-based intervention that targeted local businesses in deprived areas in the UK. To gain identification, we use data at a fine spatial scale and a regression discontinuity design exploiting the eligibility deprivation rank rule based on a pre-determined deprivation index. We detect no overall effects on employment in treated areas but find a significant displacement of employment from nearby untreated areas, corresponding to around 10% of local employment. The results suggest that indirect displacement effects may substantially weaken the ability of local support programmes targeting the non-tradable sector to reduce economic inequality.
