This is all hypothetical. I understand indifference curves. However, I don't understand how they are produced. I read this question, and the survey answer made sense to me...
Research Design: Indifference curves and budget lines
I read this paper...
It talks about creating indifference curves from prices individuals are willing to pay for certain goods, household budgets, and time series data from aggregate consumption.
So, if I had a list of prices that individuals would be willing to pay for a unit of bread, and I had a list of prices that various individuals would be willing to pay for a unit of kale, how would I find the points for an indifference curve?
If I had household budgets where I saw how much each household paid for x units of bread, and y units of kale, how would I find the points for indifference curves?
Finally, if I had a list of years, and the quantities consumed of bread and kale in a region. How would I find the points for the relevant indifference curves?
