I am "new" to economics but have some maths background (no analysis). Looking to learn how to read and make my own microeconomic models. Is there any online resources (or books) that can help me?
I would like it to walk through some key models used in microeconomics, behavioral is my interest, but most important to me is a good and simple guide. It will explain the notation used, for example why do all models have these complex equations with many integrals. It will also discuss other common assumptions, such as why certain distribution of variables are chosen (e.g., Poisson and exponential).
