Final answer:
Medium-term decisions are termed tactical, which align resources with medium-term goals and are part of the process of intertemporal decision-making, crucial for savings and investment strategies.
Step-by-step explanation:
Decisions that are made for the medium term are tactical. Tactical decisions are focused on implementing strategies that align resources and actions with medium-term goals, typically spanning from one to three years. These decisions are concerned with how to enact strategies outlined in the longer-term, strategic plans. Tactical planning often bridges the gap between longer-term strategic planning and the day-to-day, short-term operational activities. Intertemporal decision-making plays a crucial role in business as it involves the process of making choices across different periods of time, which can impact savings and investment strategies for individuals or companies.
