Calculating the Value of Prostitution

From The Guardian:

[(δU/δL) / (δU/δC) | Sp=0] ≤ w – [(δU/δr) / (δU/δC) | S = 0]

U is your satisfaction. It’s what you, as a prostitute, care about – the satisfaction you gain from selling your services. Economists like to call it “utility”, which is why they like to use the letter “U”.

L is the amount of leisure you have.

C is the amount of goods and services you, as a consumer, consume.

S is the amount of prostitution you, as a prostitute, sell to your customers.

W is the going price for prostitutes.

R is a measure of your reputation.
