1. Perfect competition short-run dynamics: Consider the market for tomatoes from problem set 1 again, but this time we'll zoom in on a couple of details, and the interplay between the market and the individual tomato-producer. We study each factor individually in order to keep things as simple as possible.
   1. *Draw a model of the market for tomatoes pre-Covid, with an individual-firm model directly next to it, representing an individual tomato farmer in a zero-economic profit position (i.e. long-run equilibrium). Explain how the profit-maximising quantity of output is determined by the individual farmer.
   2. **Show how the increase in demand for tomatoes described in the original article would have affected the market for tomatoes and the individual farmer's output and profit/loss position in the short-run. Assume ceteris paribus. What do you think will happen in the long-run?
   3. ***Draw a new individual-firm diagram. Starting again from long-run equilibrium, show how a shortage in available labour in the agricultural sector affects the individual farmer in the short run. What do you think will happen in the long-run?
