連続数学でやってきたので離散数学は苦手なんだけど,有限の特許期間など微分差分方程式を解くなど,離散系も奥深そう。
有限の特許期間はLin and Shampine (2018)が the patent length does not essentially matter with respect to endogenous growth (or at least its qualitative properties)と結論付けてからはまあ良いかなって感じ。

・This article analyzes the effects of monetary policy on economic growth via a cash-in-advance constraint on R&D investment.
・We also calibrate the model to aggregate data of the US economy and find that the growth-maximizing inflation rate is about 3%, which is consistent with recent empirical estimates.

・An endogenous growth model with creative destruction and menu costs is constructed.
・With the calibrated model, the optimal inflation rate is about ?2%.
