Final answer:
Markus Braun should start by analyzing the marginal utility of potential business locations to determine where to open new businesses. He should compare the benefits to costs, maximizing profits by choosing the location with the highest marginal utility. Research on market demand, competition, and costs further informs his decision.
Step-by-step explanation:
The first step Markus Braun should take in making a rational decision about where to open new businesses involves analyzing the marginal utility of different business locations. Marginal utility is the added satisfaction or usefulness gained from an increase in consumption or in this case, the utility of a new business location. Markus should start by identifying various potential locations and determining the additional benefit or satisfaction each location provides relative to the costs associated with opening a business there. After comparing the marginal utilities, Markus can aim for the option that offers the greatest marginal utility relative to cost, thereby maximizing the business's profits. This process is similar to the example provided where José decides how to allocate his budget between T-shirts and movies by comparing the utility gained from each additional purchase.
It is also essential for Markus to consider factors such as market demand, competition, local regulations, potential growth, and the cost of operation at each location. This involves a process of thorough research and analysis, which is foundational to making well-informed business decisions. The goal is to select a location that will offer a maximum return on investment and align with the overall strategic goals of the business.
