Suppose you are living in a dormitory and you share a common kitchen with other people who live on the same floor with you. a) Suppose the dormitory is well designed and there is always ample space and equipment for everyone on your floor to use in the kitchen. Proper cleaning is constantly done as well. What type of a good/service is the kitchen?
b) Now, suppose a problem occurred which caused other kitchens to be unusable on the other floors. This means, everyone living in the dormitory started to use the kitchen on your floor. Kitchen capacity and cleaning cannot keep up with this new amount of usage as a result. What type of a good/service is the kitchen now?
c) What problems can be faced with this type of good? How can those problems be corrected?

6. why the aggregate supply curve slopes upward in the short run in the short run, the quantity of output that firms supply can deviate from the natural level of output if the actual price level in the economy deviates from the expected price level. several theories explain how this might happen. for example, the misperceptions theory asserts that changes in the price level can temporarily mislead firms about what is happening to their output prices. consider a soybean farmer who expects a price level of 100 in the coming year. if the actual price level turns out to be 90, soybean prices will , and if the farmer mistakenly assumes that the price of soybeans declined relative to other prices of goods and services, she will respond by the quantity of soybeans supplied. if other producers in this economy mistake changes in the price level for changes in their relative prices, the unexpected decrease in the price level causes the quantity of output supplied to the natural level of output in the short run.
