故事的來源是, 因為和某位版友 msn 提到 Rebelo (1991)...
結果, 強者我老師說:
Why there is any difference between discrete- and continuous-time model?
Economically they're equivalent, and mathematically the latter is the limit of
the former, as the difference of time variables approaches zero. The usual
Lagrangian method can handle it well.
Anyway that's not my problem.
當然, 最後面那句話可能有個人情緒在, 我現在也沒辦法和老師解釋...
或許, 只是以下的感想...
當我們在解題的時候, 會不會都忘記經濟意義才是我們所想說明的結果呢?
只是感想...
