Think of items that you have purchased in a market, such as the following:
Big ticket items such as a house, an apartment rental, or a car
Ordinary items in your weekly budget, such as coffee, gasoline, bread, milk, and so on
Consider some of the following questions when writing your contribution:
What price trends have you noticed over the last few years? Do the prices fluctuate? Have prices increased or decreased?
How would you use what you have learned concerning supply and demand to explain these trends?
Have there ever been any shortages or surpluses of these items? How would you explain that?
