是的同學(xué)，這個(gè)題目是正確的。
“The “l(fā)ong run” is long enough that wages, prices, and expectations can adjust but not long enough that physical capital is a variable input. Capital and the available technology to use that capital remain fixed.
This condition implies a period of at least a few years and perhaps a decade. The truly long run, in which even the capital stock is variable, may be thought of as covering multiple decades. Consideration of the very long run is postponed to our subsequent discussion of economic growth。”摘自23年原版書
