Which statements about economic models and theories are correct? Consider micro models and the Wagner's Law.

Hey, good to see you again. Here are the solutions to your questions: Question 7: The question asks which of the statements are correct regarding economic models and theories. a) Micro models focus on the decision-making behaviour of public individuals and institutions.* Microeconomics primarily studies the decisions of individual economic agents like households and firms. While "public individuals" can be ambiguous, microeconomics generally covers individual decision-making. If "institutions" refers to private firms, this statement is correct. b) Peacock and Wiseman agrees with Wagner that a country undergoing industrialisation will experience an expansion in administrative and protection services.* Wagner's Law suggests that public expenditure increases with industrialization and economic development, including administrative and protection services.
