ECONOMIC PRINCIPLES Question 1 (Nominal & Real GDP) The price level changes may be measured using the GDP deflator which may be computed mathematically using the following formula (Krugman, 118). GDP Deflator = (Nominal GDP/Real GDP)*100 Alternatively price level changes can also be represented using inflation indicators such as CPI (Consumer Price Index) and WPI (Wholesale Price Index). These indices tend to define a basket of goods and tend to compute the weighted index every year. The change in the value of the weighted index highlights the inflation (Krugman, 145). Price increase has been quite modest in the recent times owing to the economic recovery path that the country has been since the global financial crisis. Nominal GDP is the total value of goods and services produced in the country within a given time computed at current prices. In contrast, real GDP is GDP computation carried at the prices of base year. Considering that effect of inflation is not captured in the real GDP, hence it is considered to be a superior indicator (Krugman, 112-113). Question 2 (Macroeconomics v Microeconomics) Based on the given article, it is apparent that a significant difference tends to exist between macroeconomics and microeconomics which leads to different perspectives in terms of interpreting a given phenomena. For instance, in the recent times, there has been strict control of border in southern parts of US leading to decreasing supply of cheap migrant labour. As a result from the microeconomic perspective, the underlying costs for producers of various food crops would increases which would lead to shift in the supply curve and increase equilibrium price (Arnold 93). From the macroeconomic perspective, this is expected to lead 2
