| Abstract: | Consumers have responded negatively to agricultural products originating from the Fukushima prefecture after the 2011 Fukushima Daiichi nuclear power plant incident. These consumers’ behavioural changes have caused substantial economic losses for the producers located in contaminated regions through reductions in market prices, consumption quantities and market shares. Remarkably, these losses are observed also for uncontaminated products, posing an opportunity for research in reputation damage. However, existing literature is very rare on empirical modeling of such losses. We utilise the Dixit–Stiglitz demand framework to derive a simple but efficient empirical model that uses market data to quantify reputation damage. This model estimates changes in the perceived quality of a product originating in contaminated regions in relation to those products originating from other competing regions. The model also measures subsequent loss in market share for those products grown in contaminated regions. In our application to Fukushima, results suggest that consumers’ valuation of peaches from Fukushima decreased dramatically (between 22.5% and 23.6%) in the year the nuclear accident occurred, but rapidly recovered in the following years. The results also show that the degree of impact varies across wholesale markets. Fukushima farmers lost about 13.1–18.9% of sales due to reputation damage. Estimates from our proposed models deliver meaningful information in the context of policy interventions such as transfer programmes financed by gainers to compensate reputation losses. |
