4. There are two implications of the results from nonlinear Phillips curve equation: 1) Tight labor market has higher pressure on prices than weak labor market. 2) Large unemployment gap does not result in deflation. Provide 2 possible reasons for each of these implications. (4 points) 5. The last table (below) shows your final results. Here you do not estimate Phillips curve for different unemployment rates, instead you estimate this relationship for two different time periods. It looks like your results support the flattening of Phillips curve over time. Provide two explanations for this result. (4 points) 1985-2008 2009-2019 a 0.65 0.05
