The Puzzle of US Unemployment and Declining Competition

The WS-PS model predicts that reduced market competition, which causes a downward shift in the price-setting (PS) curve, should lead to higher structural unemployment. However, this contradicts the empirical evidence from the US, where unemployment did not rise and may have even fallen during the period of declining competition. This discrepancy between the model's prediction and observed reality presents an economic puzzle.
