Imagine two economically similar countries, Country A and Country B. Over the past decade, Country A has successfully reduced its natural rate of unemployment while experiencing growth in real wages. In contrast, Country B has struggled with persistently high unemployment and stagnant real wages. Using the wage-setting and price-setting framework, identify and explain two distinct institutional or policy differences that could account for the divergent labor market performance of these two countries. For each difference, specify how it would affect the relevant curve(s) and the resulting equilibrium in each country.
