➤ How does market concentration affect the level of competition and profits?
Market concentration, measured by ratios and the Herfindahl-Hirschman Index, shows how much market share few firms hold. Higher concentration often reduces price competition and raises pricing power, improving profits. Regulation, potential entry, and product differentiation can limit these gains or increase scrutiny for collusion and antitrust enforcement.

2. How does a membership mobilization campaign differ from direct lobbying?
Membership mobilization asks constituents to contact officials, while direct lobbying involves paid advocates meeting lawmakers. Grassroots campaigns create public pressure and credibility; direct lobbying provides technical expertise and one‑on‑one access. Together they build momentum and translate constituent demand into policy language and procedural strategy.

➤ Why does unemployment rise during macroeconomic disequilibrium?
Unemployment rises when aggregate demand falls and firms cut labor demand. Search frictions and skill mismatches slow reemployment. Wage rigidity prevents quick reductions that would clear the market. The combined effect produces cyclical unemployment and longer spells of involuntary joblessness until demand recovers or policies intervene.

➤ When is the Simple Quantity Theory most accurate in practice?
The theory is most accurate in the long run when markets clear and velocity is stable. It performs poorly in the short run because prices and wages are sticky, and monetary shocks can change output and interest rates. Treat it as a long-run guide, not a short-term forecast tool.
