ぱっと見たところ、どこかで見たようなnotation...。

いや、私の本がreferenceにないことに苦情を申し立てるつもりはなく、むしろ逆。世の中のCGEモデラーの潜在意識に、本人はそうとは気づかずに、根付きつつあることにニンマリしているのである(気色悪い?)。



めざすは「よ」である。

ところで数値計算ソフトはMatlabクローンのOCTAVEの由(Major and Drucker (2015, 脚注5))。


For the simulations to be calculated it is necessary to solve the model equations. As there are actually a large number of nonlinear equations to be solved, usually it is done numerically. In our case we programmed the model equations in OCTAVE and used the built-in solver (‘fsolve’) for this purpose. This function uses a version of Newton methods to solve the system of nonlinear equations. By substituting equations into each other, the OCTAVE code reduced the dimensionality of the problem to 2*n+3, where n is the number of sectors (in this application it is 62). This meant that fsolve had to find the root of a system of 127

nonlinear equations.
