GDP is the monetary value of all finished goods and services produced within a country's borders in a specific time period, regardless of the nationality of the producer.

Consumption is the purchase of goods and services by households for their own use, and is one of the four components of GDP.

The MPC is the fraction of each additional dollar of income that is spent on consumption, and is a key determinant of the overall level of consumption in an economy.

The APC is the fraction of total income that is spent on consumption, and is a measure of the overall level of consumption in an economy.

Consumption is the purchase of goods and services by households for their own use, and is always a positive number.

Consumption cannot be greater than GDP, as GDP is the total value of all finished goods and services produced within a country's borders, and consumption is a subset of GDP.

Consumption is typically the largest component of GDP in most countries, as it represents the purchase of goods and services by households for their own use.

Consumption is affected by changes in interest rates, as higher interest rates can make it more expensive for households to borrow money and spend it on consumption.

Consumption is affected by changes in government spending, as higher government spending can lead to higher incomes for households, which can lead to higher consumption.

Consumption is affected by changes in the stock market, as higher stock prices can lead to higher wealth for households, which can lead to higher consumption.

Consumption is affected by changes in consumer confidence, as higher consumer confidence can lead to higher spending by households.

Consumption is affected by changes in the unemployment rate, as higher unemployment rates can lead to lower incomes for households, which can lead to lower consumption.

Consumption is affected by changes in the inflation rate, as higher inflation rates can reduce the purchasing power of households, which can lead to lower consumption.

Consumption is affected by changes in the exchange rate, as a stronger currency can make it cheaper for households to import goods and services, which can lead to higher consumption.

Consumption is affected by changes in the weather, as extreme weather events can disrupt production and distribution of goods and services, which can lead to lower consumption.
