A.
Kaldor–Verdoorn law
The Kaldor–Verdoorn law is an economic principle that posits a positive relationship between the growth of output and the growth of labor productivity, often used to explain cumulative and self-reinforcing processes in industrial growth.
-
B.
Solow growth model
The Solow growth model is a foundational economic framework that explains long-run economic growth through capital accumulation, labor or population growth, and exogenous technological progress.
-
C.
Ramsey–Cass–Koopmans model
The Ramsey–Cass–Koopmans model is a foundational neoclassical growth model in macroeconomics that analyzes optimal savings, consumption, and capital accumulation over time in a perfectly competitive economy.
-
D.
Lucas supply function
The Lucas supply function is an economic model developed by Robert Lucas Jr. that explains how producers’ output decisions respond to perceived price changes under imperfect information, forming a key component of new classical macroeconomics.
-
E.
Kaldor growth model
The Kaldor growth model is a post-Keynesian economic framework that explains long-run economic growth through the interaction of capital accumulation, income distribution, and demand-driven dynamics.

Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
