“deflation”的概念、定义、翻译、参考文献-科学参考

deflation

Computer

See polynomial.

Geology and Earth Sciences

The removal of material from a land surface by aeolian processes. It is most effective where extensive unconsolidated materials are exposed, e.g. on beaches, and on dry lake and river beds. The very large, enclosed hollows of many deserts (e.g. the Qattara Depression of the Egyptian Sahara) may be due to deflation.

Geography

The denudation and lowering of a surface by wind action. Washington et al. (2006) Geophys. Res. Lett. 33, L09401 show that contemporary deflation from the Bodélé Depression, Chad, is controlled by topography and wind stress. See French and Demitroff (2001) Permaf. Perig. Procs 12 on deflation hollows in periglacial environments.

Economics

1. A progressive reduction in the price level. This would make real interest rates exceed nominal interest rates, which might make it impossible to lower nominal interest rates during a slump sufficiently to make real investment appear profitable. This is known as the liquidity trap.
2. A reduction in activity due to lack of effective demand. This could be brought about deliberately by the monetary authorities in order to reduce inflationary pressure, or could occur through a collapse in confidence which the authorities were unable to avert. See also debt deflation.
