It's usually boiled which might not sound very good, but it's actually quite delicious

It actually has flavor which I think you would hardly imagine if you've got a boiled chicken here, it could be tasty

There's very little market data that's available because chicken is sold in wet markets

You simply don't have the retail scanner data that's available from grocery stores in a lot of countries
不像很多国家的零售店有零售统计数据
You could also do preference exercises that is basically asking people how much they would pay for safety. However
另外还有偏好调查,也就是询问人们愿意为安全食物多付多少,但
if they don't actually have to pay for it you're just asking them. This has very low credibility
如果不是真的支付,只是问,可信度就会很低
So I developed the first known field experiment that measures the value meat characteristics in a developing country
于是我自己开发了一种实地实验,用此来衡量发展中国家的鸡肉特征
And it's also the first known field experiment that explicitly allows for trade-off between taste and safety

It has a unique experiment design and it also involves supply chain development
