Consider a hypothetical economy where there are no taxes and no international trade. Households spend $0.50 of each additional dollar they earn and save the remaining $0.50. If there are no taxes and no international trade, the oversimplified multiplier for this economy is Suppose that the price level in our economy remains the same and that there is still no international trade. Now, however, the government decides to implement an income tax of 5% on each dollar of income. The MPC and MPS, however, remain the same as before. In this case, after accounting for the impact of taxes, the multiplier in this economy is , and a $200 billion decrease in investment spending will lead to a billion in output.

answer: in the short-run firms will respond by raising the price of turkey.

explanation: initially the long-run equilibrium is at a price of $5 per pound of turkey and a quantity of 50 million pounds per year. now, when webmd claims that a protein found in turkey will increase your expected lifespan by 4 years. the consumers demand for turkey will increase at every price shifting the demand curve to the right from d1 to d2. while, there will be no change in the supply curve in the short-run as it is not possible for producers to adjust supply so quickly. as a result the new equilibrium will occur at a higher price and a higher quantity of turkey.

thus, in the short run firms will respond by increasing the price of turkey, selling more quantity at a higher price and earning economic profits.
