Mobile Phones and Economic Development in Rural Peru
利用秘鲁农村村级面板数据，估计手机覆盖对家庭消费、贫困和极端贫困的影响，发现手机扩张使实际消费增加11%，贫困率下降8个百分点，极端贫困下降5.4个百分点，且受益不限于拥有手机的家庭。
We estimate the effects of mobile phone coverage on different measures of economic development. We exploit the timing of mobile coverage at the village level merging it with a village-level panel dataset for rural Peru. The main findings suggest that mobile phone expansion has increased household real consumption by 11 per cent, reduced poverty incidence by 8 percentage points and decreased extreme poverty by 5.4 percentage points. Moreover, those benefits appear to be shared by all covered households regardless of mobile ownership.
