What is an Argument?

• Claim: \(A \uparrow \to B \uparrow\)
• Argument: because X (Reason)
  • theoretical / empirical to support the claim
• Purpose: convince audience of \(\to\) claim

Example from AJR 2001

A \(\downarrow \implies\)	B \(\downarrow\)
Quality of current institutions	Current Performance
Empirical: Protection against Risk of Expropiation	reduces GDP per Capita

Elements of X

• Theory: countries with better property rights invest more in physical capital
• Empirically: Figure 2 from Paper

Counterarguments:

• reversed causality: \(B \downarrow \to A \downarrow\)
• omitted vairable \(A \downarrow \& B \downarrow\) because of W

Counter Counterarguments

• accept limitations of argument
• add reasons to X (X1,X2,…)
