The Impact of Food and Economic Crises on Diet and Nutrition
研究了1990年代中期保加利亚重大危机期间食品价格和收入冲击对饮食与营养的影响，发现危机改变了需求弹性，提醒政策制定者谨慎使用危机前的模拟结果。
The conventional view is that inelastic demand makes consumption of staple foods resilient to major price and income shocks. We explore the dietary and nutritional implications of a major shock in Bulgaria in the mid-1990s with data from before, during and after the shock. While demand for foodstuffs may remain relatively unchanging in environments characterised by stable food prices and incomes, economic crises and significant price spikes appeared to induce dramatic changes in price and income demand elasticities. We therefore suggest the use of caution in basing policy prescriptions on randomly available pre-crisis simulations.
