We now want to determine if are economies of scale, constant economies of scale, or diseconomies of scale from Q=200 to Q=400 Economies of scale is determined by whether the cost per unit, AKA the Average Cost is increasing, decreasing or constant. If Average Cost is decreasing, then there are "economies of scale" If Average Cost is increasing, then there are "diseconomies of scale" If Average Cost is constant, then there are "constant economies of scale" What are the scale economies here?

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.
