Exchange Rate Pass-through in South Africa: Panel Evidence from Individual Goods and Services
研究南非汇率变动对消费品和进口商品价格的传递效应，发现消费品价格传递率低（约16%），进口商品传递率高（约60%），且购买力平价偏离的消失速度较快。
Abstract This study estimates pass-through for South Africa using samples of final goods and services, and homogenous imports. Estimated pass-through to consumer goods prices is low, roughly 16 per cent in the two years following an exchange rate change; surprisingly, it is somewhat higher for services. Deviations from long run PPP appear to disappear relatively quickly, with a half-life of about 16 months. For imports, pass-through estimates are much higher, averaging around 60 per cent, but with wide source-country variation. Finally, there is virtually no support for a simple linear trend change in either pass-through or in reversion to PPP during the sample.
