Macroeconomics: GDP, Unemployment & Monetary Policy

To calculate GDP using the expenditure formula, we sum consumer spending, investment, government spending, and net exports (exports minus imports). Here, consumer spending is $9,500, investment is $3,200, government spending is $4,100, exports are $2,300, and imports are $2,900. First, calculate net exports: $2,300 - $2,900 = -$600. Then, add all components: $9,500 + $3,200 + $4,100 - $600 = $16,200. This total represents the economy's output, confirming the calculated GDP.

To calculate the real GDP growth rate, use the formula: \((\text{New GDP} - \text{Old GDP}) / \text{Old GDP} \times 100\). Here, the old GDP is $1.92 trillion and the new GDP is $1.98 trillion. The difference is $0.06 trillion. Dividing this by the old GDP gives \(0.06 / 1.92 \approx 0.03125\). Multiplying by 100 converts this to a percentage, resulting in a growth rate of approximately 3.13%. This reflects the economy's growth over the specified period.

When a customer deposits $12,000 in a bank with a reserve ratio of 8%, the bank must keep 8% of the deposit as reserves, which amounts to $960. The remaining $11,040 can be loaned out. Through the money multiplier effect, calculated as 1 divided by the reserve ratio (1/0.08 = 12.5), the total potential new money created is $11,040 multiplied by 12.5, resulting in $138,000. This figure represents the maximum amount of new money that can be created in the banking system, excluding the original deposit.

Cost-push inflation occurs when the overall price levels rise due to increases in the cost of production. In this scenario, a spike in oil prices raises the costs for businesses that rely on oil for production and transportation. As these costs increase, companies pass them on to consumers in the form of higher prices, leading to inflation. This situation highlights how external factors, such as commodity price increases, can disrupt supply chains and elevate production costs, resulting in inflationary pressures in the economy.

Factors that shift Aggregate Supply (AS) to the right enhance production capacity or reduce costs. Improvement in technology increases efficiency, enabling more output with the same resources. A decrease in energy prices lowers production costs for businesses, encouraging higher supply. An increase in labor productivity means workers can produce more in the same amount of time, further boosting supply. In contrast, increases in government transfer payments do not directly affect production capabilities, while rising corporate income taxes can deter investment and reduce supply.

When the Bank of Canada raises the overnight interest rate, borrowing becomes more expensive, leading to a decrease in consumer and business loans. As a result, both investment and consumption decline, causing aggregate demand (AD) to shift left. This reduction in AD helps to alleviate inflationary pressures in the economy, as lower demand typically results in lower price levels. Consequently, the contractionary monetary policy effectively works to stabilize prices by cooling off economic activity.

Real GDP is adjusted for inflation, which allows it to reflect the true value of goods and services produced in an economy over time. Unlike Nominal GDP, which measures economic output at current prices and can be distorted by price changes, Real GDP provides a clearer picture of economic growth by accounting for changes in price levels. This adjustment enables better comparisons of economic performance across different time periods, making Real GDP a more accurate indicator of an economy's health and growth trajectory.

Welfare payments, Employment Insurance (EI), and Canada Pension Plan (CPP) benefits are considered transfer payments because they involve the redistribution of income rather than the creation of new goods or services. These payments do not reflect economic production, which is the primary focus of Gross Domestic Product (GDP) calculations. GDP measures the total value of all final goods and services produced within a country over a specific period, and since transfer payments do not contribute to this production, they are excluded from GDP.

GDP per capita is a more effective measure of living standards because it divides a country's total economic output by its population. This provides a clearer picture of the average income and economic well-being of individuals within different countries. It enables meaningful comparisons between nations of varying sizes, highlighting differences in living standards that total GDP alone cannot reveal. By focusing on per person metrics, GDP per capita offers insights into how wealth is distributed and experienced by the average citizen, making it a more relevant indicator of economic health and quality of life.
