➤ How does an identification strategy affect confidence in causal claims?
A clear identification strategy determines whether correlations reflect causal effects. Economists rely on exogenous variation from experiments, instruments, policy changes, or timing differences to isolate causality. They justify assumptions like exclusion restrictions or parallel trends and run diagnostics to assess whether those assumptions plausibly hold.
