The problem with ceteris paribus clauses in economics is that they are not fully specified, making it hard to test economic laws. Daniel Hausman's ideas on this issue suggest that economic generalizations with vaguely specified clauses cannot be effectively evaluated with empirical evidence. While his explanation of fundamental economic laws is convincing, it is difficult to test them in real-world settings. Even though derived economic laws could theoretically be tested, the inclusion of subjective factors in the clauses makes them practically untestable. The main issue with ceteris paribus clauses in economics lies in their lack of clear articulation by social and economic theory.
