From the presented macroeconomic data for 2010, we can infer that the GDP deflator is 1.33, indicating inflation has occurred since the base year. This calculation is done by dividing nominal GDP by real GDP and multiplying by 100. Other options provided cannot be inferred accurately from the data given.
Looking at the macroeconomic data provided for the economy in the year 2010, we can make several inferences.
Nominal GDP is the gross domestic product measured using current prices, without adjusting for inflation.
In contrast, real GDP is adjusted for inflation and reflects the actual value of goods and services produced.
To calculate the GDP deflator, which helps to measure inflation, we can divide the nominal GDP by real GDP and then multiply by 100.
Using the given data:
Nominal GDP = $1,000 billion
Real GDP = $750 billion
The GDP deflator = (Nominal GDP / Real GDP) × 100 = ($1,000 / $750) × 100 = 1.33 × 100 = 133
The GDP deflator being greater than 100 indicates that there has been an inflation since the base year.
It also shows that nominal values are higher due to inflation, not necessarily due to an increase in production.
The last piece of information, the money supply of $200 billion doesn't directly tell us whether there's a monetary surplus without more context such as demand for money or economic equilibrium.
Finally, since there's no base year for real GDP growth presented, asserting that the real GDP growth rate is 25% is not possible from the given data.
Thus, the correct inference from these indicators is that the GDP deflator is 1.33 (B).
