Good Questions!

A consumer has income of $9,000. Coffee costs $3 a cup and pastries cost $2 each. Draw the consumer budget constraint. What is the slope? What would happen if income rises to $12,000? What would happen if the price of coffee falls to $2 per cup? What would happen if the price of pastries rises to $4.50 each?

What is the consumer indifference curve for 1 yuan notes and 1 yuan coins most likely to look like?

What are the four properties of indifference curves?

Analyze This

There’s a lot more than minimum wage going on here:

Wendy’s (WEN) said that self-service ordering kiosks will be made available across its 6,000-plus restaurants in the second half of the year as minimum wage hikes and a tight labor market push up wages.

It will be up to franchisees whether to deploy the labor-saving technology, but Wendy’s President Todd Penegor did note that some franchise locations have been raising prices to offset wage hikes.

McDonald’s (MCD) has been testing self-service kiosks. But Wendy’s, which has been vocal about embracing labor-saving technology, is launching the biggest potential expansion.

Wendy’s Penegor said company-operated stores, only about 10% of the total, are seeing wage inflation of 5% to 6%, driven both by the minimum wage and some by the need to offer a competitive wage “to access good labor.”

It’s not surprising that some franchisees might face more of a labor-cost squeeze than company restaurants. All 258 Wendy’s restaurants in California, where the minimum wage rose to $10 an hour this year and will gradually rise to $15, are franchise-operated. Likewise, about 75% of 200-plus restaurants in New York are run by franchisees. New York’s fast-food industry wage rose to $10.50 in New York City and $9.75 in the rest of the state at the start of 2016, also on the way to $15.

Wendy’s plans to cut company-owned stores to just 5% of the total.

Still, Penegor said that increased customer counts more than price hikes drove the chain’s 3.6% same-store sales increase in the first quarter.

Although profit exceeded Wall Street estimates, Wendy’s shares dived nearly 9% Wednesday because of weak second-quarter sales.

Besides modeling the effect of minimum wage increases, there’s a lot of interesting things we can get into using this semester’s topics. Be ready to discuss (and model) factor substitution, the relationship between revenue, prices and profits, time value of money and short and long term price elasticity.
