Shore Lightning Inc. is the manufacturer of LED light bulbs used in stadium scoreboards around the world. They are looking into opportunities in England and Thailand. Based on their analysis, they think the two options will deliver the following annual results: England Thailand Revenues: $750,000 $600,000 Labor/Material Costs: $200,000 $150,000 Profit: $550,000 $450,000 The daily costs for the opportunity in England are broken down as follows: Labor Cost: $2.50 per light bulb Material Cost: $4.50 per light bulb Machine Cost: $1.50 per light bulb Daily fixed costs: $2,000 Over the next 10 years, the company wants to expand the amount of technology it uses in order to reduce its labor costs in the production of light bulbs. They believe that the new technology will allow them to triple the output of light bulbs daily with only a slight increase in the amount of labor hours. Labor per light bulb will decrease from the current rate of $2.50 to $1.50 per light bulb because of the increase in production. What is the opportunity cost of operating in Thailand instead of England?

A mid-sized agribusiness company in the U.S. is exploring new opportunities of expansion. It currently focuses on growing wheat, corn, and soybeans for human consumption, along with supplying feed products to farmers who raise and sell chickens. The company is exploring adding dairy products to their business line by investing in dairy farms. The U.S. government has set the price of milk that dairy farmers can charge at $1.75 per gallon. At this price, farmers are unwilling to supply enough milk to meet the demand. As part of the expansion into dairy products, the company is trying to determine the states where the dairy farms should be located. In a western state that has many dairy farms, the state minimum wage rate is $12 per hour. This wage rate is higher than the average national labor wage rate. The company wants to focus on organic dairy products because of there is increased demand in the organic market and willingness of consumers to pay more. The organic market is a challenging market for consumers since it is difficult to determine which products are truly organic and which are not. To help ease consumers' concerns, the company plans on labeling its dairy products as organic and will work with dairy farms that specialize in organic farming. During the exploration phase, the company discovered that a dairy farm in the western state had accidentally destroyed the natural habitat of a federally protected bird. The farm was mandated by the government to replant trees on 50 acres of land in hopes of reestablishing the habitat. The cost of replanting the trees resulted in an increase in the cost of producing a gallon of milk at this farm. Which strategy should the company use to help ease consumers' concerns in the organic dairy market?
Better labeling
