What Are the Implications for 2SLS Estimators If Reduced Form

question 7

Multiple Choice

What are the implications for 2SLS estimators if reduced form parameter estimates are statistically insignificant?

• A)still consistent in large samples,but no longer BLUE
• B)there will be correlation in the structural equations,causing estimators to be inconsistent
• C)there are no consequences,only structural parameters matter
• D)small sample properties no longer hold,but asymptotic properties still apply

Definitions:

Gas Exchange

The biological process through which organisms exchange oxygen and carbon dioxide with their environment, essential for respiration.

Diffusion

The movement of molecules or particles from an area of higher concentration to an area of lower concentration until equilibrium is reached.

Diffusion

The movement of particles from an area of higher concentration to an area of lower concentration, leading to an even distribution.

Gas Exchange

The biological process through which different gases (like oxygen and carbon dioxide) are transferred in opposite directions across a respiratory surface.
