In the interview with Professor Laibson, I thought it was interesting to hear the discussion about potentially being able to create equations to model all types of economic activities similar to how we have specific formulas to evaluate nominal values. When talking about the economy, the subject of self-interest comes up a lot since we are trying to make predictions on growth of wealth. This makes creating equations to model behavioral economics very difficult since we have to assign a nominal value to something that is different for each person. For example, when dealing with the economy, it is inevitable that some may be more greedy than others. This behavior is varied among everyone and outliers can cause a model to be skewed heavily.
