 note = {In the era of increasing world population and food crisis, when choosing safe domestic foods orlow-priced imported foods which may cause health damages, the bias against health risk based onconsumers’ personal income level can play a significant role. In this study, focusing on such biases,we analyze the determination of food price and biased demands for unsafe foods, which are affectedby fluctuation of income distribution and population growth.The results are as follows. First, when a population growth does not fluctuate the incomedistribution and income level, this population growth never cause price hikes. However, apopulation growth that expands the income difference and increases low-income bracket raises eventhe price of low-priced problematic foods, while the economic growth with no population growthdecreases the price of problematic foods. Second, the large income difference should be reformedsince the large bias makes the worsening of quality control connected with price hike. Moreover,the improvement of food quality mitigates the problem that low-income consumers tend to sufferthe health damages., revised version ファイル追加 (2015.1.5)},
