A government is considering two distinct policy proposals aimed at influencing the labor market. Policy A involves a significant increase in the generosity and duration of unemployment benefits. Policy B involves a widespread deregulation effort designed to increase competition among firms in the product market. Analyze each policy's effect on the wage-setting (WS) and price-setting (PS) curves. Then, evaluate which policy is more likely to result in a lower natural rate of unemployment in the long run, justifying your conclusion.
