  1. Why ceteris paribus laws are excluded from economics

p.137 #1

Economics studies say, economics laws are ceteris paribus laws.

the conventional regularity account of laws

- a theorectical laws is a statement of some kind of regular association,

  and is supposed to hold 'by necessity'.

- laws of economics cannot be real laws.

problem of the idea of necessity

: it is difficult to explain what constitutes the difference 

 between law-like regularities and these that hold only by accident.

in this paper, Cartwright focuses on the associations themselves.

p.137 #2

These two assumptions work together to ban ceteris paribus laws from the nature.

(i) the kinds of properties that appear in Nature's laws must be observable of measurable or occurrent

(ii) that quantities that are admissible into the domain of science are facts about patterns of their co-occurrence.

(i) and (ii) tell us that all the quantities we study are qualitatively alike.

As a consequence it becomes impossible to find any appropriate category 

that would single out conditioning factors for laws from the factors.
