I would suggest you to illustrate the above-themes by the housing market in Hong Kong. Nowadays, there is increase in demand on housing as wages rise for workers and employees, negative interest rate, inflation...... However, the supply decrease as the home-owners and properties developer delay their selling of houses, thus pushing up the prices.
