These new videos taking students through the components of aggregate demand using data from the UK economy.
Aggregate Demand - Components of AD for the UK
The concept and measurement of aggregate demand is covered in this revision video. We look at data on the components of AD for the UK economy to apply the idea.
Aggregate Demand Curve Explained
In this video we look at the aggregate demand curve and explain why there is usually an inverse relationship between the general price level and aggregate demand for domestically produced goods and services. Movements along the AS curve are caused by changes in the general price level (GPL).
Aggregate Demand - Explaining Shifts in the AD Curve
In this video we will explore some of the factors that can cause a shift in the position of the aggregate demand curve. Shifts in the aggregate demand curve are caused by factors independent of changes in the general price level.
Aggregate Demand - Examples of Chains of Reasoning
In this video we look at three examples of chains of reasoning explaining factors that might cause a change in aggregate demand.
Aggregate Demand - Consumer Spending
Consumer spending is the biggest single component of aggregate demand. In this short video we look at some of the key factors that determine the level and growth of consumer demand for goods and services in the macroeconomy.
Aggregate Demand: Marginal Propensity to Consume
The concept of the marginal propensity to consume is explored in this short revision video.
Aggregate Demand - Household Saving and AD
In this video we look at household saving including the concepts of the savings ratio and the marginal propensity to save. Changes in how much families choose to save out of their disposable income can have a big impact on consumer spending and hence, the level of AD.
Aggregate Demand: Investment Spending
In this video we look at the difference between gross and net investment, consider factors that influence levels of planned capital spending by businesses and focus on the importance of investment to both the demand and supply-side of an economy in helping to meet macroeconomic objectives.
Aggregate Demand: Government Spending and AD
In this video we focus on different types of government spending and the contribution they can make to aggregate demand.
Aggregate Demand: Exports and AD
Exporting is the act of selling goods and services to another country. Income from exports counts as an injection into the circular flow of income and adds to aggregate demand (AD).
