  What is positive and Normative Statements?


  Positive statements

  Descriptive

  Usually acceptable to all economists

  Usually use data and empirical evidence,


  Example:

  The inflation rate in 1999 is 2.5 per cent;

  The Quantity Theory of Money can be used to explain why inflation occurs in an economy.

  The Index of Retail Price of UK in 1986 is 103.4



  正面陳述

  描述性

  通常為所有經(jīng)濟學(xué)家所接受

  通常使用數(shù)據(jù)和經(jīng)驗證據(jù),


  例子:

  1999年通貨膨脹率為2.5%;

  貨幣數(shù)量論可以用來解釋為什么一個經(jīng)濟體會發(fā)生通貨膨脹。

  1986年英國零售價格指數(shù)為103.4


  Normative statements

  Involves value judgement

  Often drawn from the economist’s personal views, political beliefs and ethics.


  Example:

  The government should cut fuel tax to reduce the rate of inflation;

  Public sector workers should reduce their demands for higher wages


  規(guī)范性聲明


  涉及價值判斷

  通常來自經(jīng)濟學(xué)家的個人觀點、政治信仰和倫理。


  例子:

  政府應(yīng)削減燃油稅以降低通貨膨脹率;

  公共部門工人應(yīng)減少對更高工資的要求
