To describe: The four main components of aggregate
Answer to Problem 1TY
Four main components are consumption, investment, Government expenditure and net exports.
Largest component is consumption expenditure and the smallest one is net exports.
Explanation of Solution
The four main components are as follows:
Consumption: It can be stated as the spending for purchasing goods and services. It always depends positively on the disposable income and depends on the size of income and marginal propensity to consume. The consumption will be greater when the disposable income is greater.
Investment : It is to enhance the productivity by adding to the existing capital. It can be machinery, payment for additional labor, addition of stock capital, etc.
Government expenditure : This includes the purchase of goods and services by government at a point of time and is denoted by G.
Net exports: It can be defined as the difference between imports and exports. The money value will be more when exports are greater than the imports and vice versa.
The aggregate demand can be calculated by the equation.
From the above equation, it is clear that the aggregate demand is the sum of consumption, investment, government expenditure and net exports.
The largest component is the consumption expenditure as it constitutes of two-third of the overall expenditure. While net exports is the smallest component as it is the difference between the imports and exports, the value of this difference would be smaller
Introduction: Aggregate demand is an economic indicator of the overall demand for all finished goods and services produced in an economy. At a given price level and point in time, aggregate demand is defined as the cumulative amount of money traded for certain goods and services.

With this notation, 2.3045 Q would be a double flush since every card is a diamond and a heart. • Wild Cards: A wild card counts as having every suit and every denomination. Denote wild cards with a W; if there are multiple, we will denote them W₁, W2, etc. With this notation, W2 20.30054 would be both a three-of-a-kind (three 2's) and a flush (5 diamonds). If we add multiple wild cards to the deck, they count as distinct cards, so that (e.g.) the following two hands count as "different hands" when counting: W15 5Q and W255◊♡♡♣♣ In addition, 1.

- In a classic oil-drilling example, you are trying to decide whether to drill for oil on a field that might or might not contain any oil. Before making this decision, you have the option of hiring a geologist to perform some seismic tests and then predict whether there is any oil or not. You assess that if there is actually oil, the geologist will predict there is oil with probability 0.85 . You also assess that if there is no oil, the geologist will predict there is no oil with probability 0.90. Please answer the two questions below, as I am trying to ensure that I am correct. 1. Why will these two probabilities not appear on the decision tree? 2. Which probabilities will be on the decision tree?arrow_forwardAsap pleasearrow_forwardnot use ai pleasearrow_forward

Use yearly data from FRED website from 1971 to 2020: (i) The Canadian Dollars to U.S. Dollar Spot Exchange Rate (ER) (ii) Consumer price index for Canada (CAN_CPI), and (iii) Consumer price index for the US (US_CPI). Inflation is measured by the consumer price index (CPI). The relative PPP equation is: AE CAN$/US$ ECAN$/US$ = π CAN - πUS Submit the Excel sheet that you worked on. 1. First, compute the percentage change in the exchange rate (left-hand side of the equation). Caculate the variable for each year from 1972 to 2020 in Column E (named Change_ER) of the Excel sheet.
