KEY TAKEAWAYS

Carl Menger, an Austrian economist who wrote Principles of Economics in 1871, is considered by many to be the founder of the Austrian school of economics.

The key ideas of the Austrian school have evolved over the years through the input of various economists.

Other than Carl Menger, the Austrian school also includes names like Ludwig von Mises, Eugen von Bohm-Bawerk, and Friedrich Hayek.

The Austrian school uses logic of a priori thinking to discover economic laws of universal application, whereas other mainstream schools of economics make use of data and mathematical models.

The early concepts of the Austrian school contributed significantly to the theory of diminishing marginal utility.

Austrian School of Economics
By Peter J. Boettke
https://www.econlib.org/library/Enc/AustrianSchoolofEconomics.html

The Science of Economics

Proposition 1: Only individuals choose.

Proposition 2: The study of the market order is fundamentally about exchange behavior and the institutions within which exchanges take place.

Proposition 3: The “facts” of the social sciences are what people believe and think.

Microeconomics

Proposition 4: Utility and costs are subjective.

Proposition 5: The price system economizes on the information that people need to process in making their decisions.

Proposition 6: Private property in the means of production is a necessary condition for rational economic calculation.

Proposition 7: The competitive market is a process of entrepreneurial discovery.

Macroeconomics

Proposition 8: Money is nonneutral.

Proposition 9: The capital structure consists of heterogeneous goods that have multispecific uses that must be aligned.

Proposition 10: Social institutions often are the result of human action, but not of human design.

These are the key thought leaders of Austrian economics.
