Microeconomics is a comprehensive exploration of how individuals, firms, and governments strategically allocate scarce resources to address competing needs and wants. The book begins by introducing foundational principles such as trade-offs, opportunity costs, and the signal role of prices in coordinating economic decisions, then delves into supply and demand dynamics, elasticity, and consumer choice through analytical models and real-world applications. It further examines the operational decisions of firms—from production techniques and cost analysis to market structures like competitive markets, monopolies, oligopolies, and even game theory scenarios—illustrating how varied market conditions influence pricing and output. By following the decision-making processes of key economic agents and applying theoretical models to practical situations, the text provides an integrated framework for understanding both individual behavior and overall market efficiency.

Problem 1
In a commentary piece on the rising cost of health insurance (“Healthy, Wealthy, and Wise," Wall Street Journal, May $4,2004,$ A20 $,$ economists John Cogan, Glenn Hubbard, and Daniel Kessler state, "Each percentage-point rise in health-insurance costs increases the number of uninsured by 300,000 people." Assuming that their claim is correct, demonstrate that the price elasticity of demand for health insurance depends on the number of people who are insured. What is the price elasticity if 195 million people are insured? What is the price elasticity if 250 million people are insured? (Hint: See Solved Problem $3.1 .)$

Sometimes a group of hungry students will go a restaurant and agree to share the bill at the end regardless of who orders what. What is the implication of this fee-sharing arrangement on the size of the overall bill? Why?

Problem 3
The estimated demand function (Moschini and Meilke, 1992 , for Canadian processed pork is $Q=161-20 p+20 p_{b}+3 p_{\mathrm{c}}+2 Y,$ where $Q$ is the quantity in million kilograms (kg) of pork per year, $p$ is the dollar price per kg (all prices cited are in Canadian dollars), $p_{b}$ is the price of beef per $\mathrm{kg}, p_{c}$ is the price of chicken in dollars per $\mathrm{kg},$ and $Y$ is average income in thousands of dollars. What is the demand function if we hold $p_{b}, p_{c},$ and $Y$ at their typical values during the period studied: $p_{b}=3.2, p_{c}=3 \frac{3}{10},$ and $Y=13 ? \mathbf{A}$

Problem 6
Should a firm shut down (and why) if its revenue is $R=\$ 1,000$ per week a. its variable cost is $V C=\$ 500,$ and its sunk fixed cost is $F=\$ 600 ?$ b. its variable cost is $V C=\$ 1,001$, and its sunk fixed cost $F=\$ 500 ?$
