Video: Economic Metrics

In this lesson, Nick Palazzolo, CPA, dives into key economic indicators that are essential for grasping the bigger financial picture. Covering the marginal propensity to consume (MPC), he illustrates what happens when individuals receive a pay raise and how that impacts spending versus saving behaviors. The lesson also demystifies the consumer price index (CPI), detailing how it reflects the changing prices urban consumers face for a basket of goods and services over time. To cap it off, Nick breaks down the gross domestic product (GDP), explaining its significance as the total market value of all goods and services produced within a country and how it's computed using the expenditure approach. This lesson is pivotal for anyone looking to get a handle on the economic factors that drive financial decision-making and reporting.

The economic metrics to understand and be familiar with include the marginal propensity to consume, the consumer price index, and the gross domestic product and its formula for GDP. Let's start off with the MPC, the marginal propensity to consume. This is the proportion of a raise in pay that is spent on the consumption of goods and services. So if you get a 10% raise, the marginal propensity to consume is the percentage of that 10% which you spend on goods and services, as opposed to saving it.

For example, if you get a $1000 raise and you spend $1000 on a new TV, then the marginal propensity to consume for you would be 100%. If you put all of the money in the bank and are more responsible with it, then the marginal propensity to consume would be zero. Generally, the wealthier and higher income individuals will have a lower marginal propensity to consume, as they are more likely to save and invest their money.

Next is the consumer price index, which is a measure of the average change over time in prices paid by urban consumers. This is done by creating a market basket of consumer goods and services, and weighting the inflation increase of each item by the percentage of the consumer's income spent on it.

Finally, there is the gross domestic product, which is a monetary measure of the market value of all final goods and services produced in a specific time period by countries. This is calculated using the expenditure approach, which takes into account government spending, investment by private industry, consumer spending, and exports net of imports.
