Mico-Econ Ch.1 Economic Mechanisms & Principles

The Invisible Hand Mechanism (Adam Smith)

The process where self-interested economic actors acting freely bring about a market equilibrium and price distribution that benefits society as a whole.

Drivers of the Invisible Hand

1. Efficient production to maximize profit;

2. Low price setting to undercut competitors;

3. Reallocating capital to high-demand industries.

Equilibrium Mechanism

An economic state where no actor has an incentive to change behavior, reached primarily through price adjustments that guide resource allocation.

Causes of Market Failure

1. Externalities (impacts on bystanders);

2. Market power (undue influence on prices);

3. Goods unsuited for market trade (e.g., donor organs).

Efficiency vs. Equity Trade-off

Efficiency means maximizing benefits from scarce resources (economic decisions); Equity means distributing resources fairly among society (political decisions).

Reasons Economists Disagree

1. Disagreements over the validity of alternative positive theories;

2. Differing values leading to different normative policy goals.

Purpose of Economic Models

Simplified theoretical tools using explicit assumptions to model human behavior, explain economic operations, and predict outcomes.
