Final answer:
To establish a beverage marketing budget, businesses use the utility-maximizing budget set framework, taking into account external factors such as taxes which affect consumer behavior and related product sales.
Step-by-step explanation:
A method that can be used for establishing the beverage marketing budget is understanding the utility-maximizing budget set framework. This approach involves considering the effects of external factors, such as taxes, on consumer behavior and how this influences spending on different products. For example, when the government increases taxes on alcohol, this not only impacts the sales of alcoholic beverages but can also affect the sales of related items like snacks in restaurants. Businesses must, therefore, consider these ripple effects when setting their marketing budgets.
