Answer:
1. Fall
2. Reducing
3. Fall Below
Step-by-step explanation:
1. FALL. Due to the Menu Costs (costs to suppliers of having to constantly update prices) of inflation being too high for the Catalogue sellers. They leave the prices where they are at 100. Prices have fallen to 90 though so people will therefore buy less from catalogues as they will be considered more expensive.
2. REDUCING. Firms dealing with Catalogues will respond by reducing output. The more output they supply, the more variable costs they deal with. Seeing as their Demand has fallen leading to a reduction in profitability, they will scale back operations to try to spend less and also because less people are buying output.
3. Fall Below. The Quantity of output supplied was dependant on a price level of 100. That was where the natural rate was. Now as prices have fallen and quantity supplied have gone with them, the effect would be a fall Below the Natural Output Level.
