B. SKILLS APPLICATION American antitrust regulators rule that the Ford and Hyundai merger can proceed NEW YORK The US rate of inflation remains low. Washington. November 16, 2017. REUTERS/MILENA BAENSCH The consumer price index in the US rose by just 0.2% in November from the year before, compared to 0.1% in October and -0.5 in September. The core inflation rate which excludes food and energy costs, increased 0.5% year-onyear. The producer price index, based on 625 products, showed a much higher increase of 4.4%. This reflected increases in agricultural, mining and industrial costs. The falling and persistently low rate of inflation reflects consumer caution in spending, which is due to political turmoil in the Whitehouse, and the dysfunctional Republican majority House and Senate failing to pass any real legislative agenda. In a statement from the Whitehouse, President Trump decried the fake news establishment and said that low and falling prices were great news, I have heard from hundreds of people that tell me that they like lower prices. I m going to work to get prices even lower. It's going to be amazing. Believe me." 13 P a g e
QUESTIONS 1. Outline the following terms: [6 marks] i. Consumer price index (CPI) ii. Producer price index (PPI) iii. Core inflation 2. Using examples from the article, distinguish between the concepts of inflation, deflation and disinflation. 3. Explain how an increase in the US PPI is likely to predict changes in the CPI affecting US households. 4. Use diagrams to distinguish between demand-pull inflation and cost-push inflation. 5. Explain why the rate of US inflation is more likely to be a product of demand-pull inflation rather than cost-push inflation? 6. Explain why President Trump is misguided in his thinking about deflation being a positive thing for the US economy? HIGHER LEVEL QUESTION ONE: LOW AND STABLE RATE OF INFLATION 1.

Answer the following questions regarding the Phillips curve: a. Outline the concept of the Phillips curve. [3 marks] 16 P a g e
2. Explain how events in the 1970-1980s established that the relationship between inflation and unemployment in the short-run was not fixed and permanent (i.e., unstable). b. Outline the concept of stagflation using the AD/AS model. [3 marks] 17 P a g e
c. Explain how the relationship between the short-run position of the Philips curve and shifts in the short-run aggregate supply curve can account for stagflation. [6 marks] AD/AS model Phillips curve d. Use diagrams to distinguish between the Phillips curve in the short-run and in the long-run. Short-run Phillips curve Long-run Phillips curve 18 P a g e
