RedGоld Fаrms is а firm thаt prоduces and sells tоmatoes. The market for tomatoes is perfectly competitive. The Marginal Private Benefit (MPB), Marginal Social Benefit (MSB), and Marginal Social Cost (MSC) are shown on the following graph. This graph shows RedGold Farms’ market for tomatoes, with price per unit on the vertical axis ranging from $4 to $8, and quantity of output on the horizontal axis. The downward-sloping Marginal Private Benefit (MPB) curve and the downward-sloping Marginal Social Benefit (MSB) curve are drawn, with MSB above MPB. An upward-sloping curve labeled MPC equals MSC represents marginal private and social costs. Horizontal dashed lines indicate price levels at $4, $5, $7, and $8, while vertical dashed lines mark quantities at Q0, Q1, and Q2. The graph illustrates potential market outcomes, showing where private and social benefits differ from social costs in a perfectly competitive market for tomatoes. Use the graph to answer questions a-d. Identify the kind of market failure represented by this graph. (3 points) Using numbers from the graph, identify the marginal external benefit. (3 points) Assume the tomato market is in short-run equilibrium and RedGold hires workers in a perfectly competitive labor market at a wage of $20 per hour. The marginal product of the last worker hired was 6 units of tomatoes per hour. Calculate the change in RedGold's profit per hour from the last worker hired. Show your work. (3 points) Suppose that the government decides to provide a per-unit subsidy to consumers who buy tomatoes. How would the per-unit subsidy affect RedGold's marginal revenue product curve? Explain. (3 points) Instead of hiring workers in a perfectly competitive labor market, assume RedGold hires workers in a monopsony labor market. Will the number of workers hired increase, decrease, or stay the same? Explain. (3 points)
