Imagine a country where the average real wage for manufacturing workers has stagnated for the past two decades, despite overall economic growth. During this same period, the percentage of the workforce belonging to a union has significantly declined, and the government has enacted policies that reduce the minimum wage relative to the average wage. Analyze how the decline in union membership and the changes in government policy could have contributed to the observed wage stagnation for these workers. In your answer, explain the distinct mechanisms through which each of these factors influences labor market outcomes.
