Ask the expert for help: What does the taste parameter mean in economics?

Taste parameters can be understood as preference parameters, which generally refer to the distribution of consumer demand preferences. I am not an English major, and my translation is not very elegant, but it is ok to read the original work of general econometrics I said, and it is very important to understand it in context.

For example, the fourth chapter analyzes the conditions of second-degree price discrimination when enterprises know that consumers' taste parameters are evenly distributed.

Translation:

The fourth chapter analyzes the conditions for monopoly manufacturers to use two kinds of constraints to implement second-degree price discrimination when they know that consumer demand preference parameters obey uniform distribution.

Another example is: if the distribution of consumer's taste parameters is unknown, how can he decide the quality difference of such products?

How can a consumer decide the different supply of various products when the distribution of demand preference in the market is uncertain?

I hope these two examples will help you understand.
