Final answer:
Service exchange decisions in a model of internal/external service exchange depend on several factors, including exchange rate effects, market structures, and economic decision-making approaches, as well as social and resource exchange theories.
Step-by-step explanation:
Identify the true statements about the aspects on which service exchange decisions depend according to a proposed model of internal/external service exchange involves multiple factors. These factors may include but are not limited to the effects of changes in exchange rates on imports and exports, the type of market structures, and the economic approaches to decision-making. One must also consider the social exchange theory, where individuals engage in relationships based on the mutual benefit and resource exchange, highlighting the importance of resource management in maintaining social networks, especially in older populations. Additionally, tradeoff diagrams can be used to understand the decisions related to imports and exports, as well as the influence of public enterprise on market decisions. The United States' lower dependency on international trade, compared to smaller or European Union member countries, illustrates a practical example of such service exchange decisions within a global marketplace. Similarly, the challenges faced by regions like Africa and Southeast Asia in accessing resources, as seen in the AIDS epidemic, demonstrate the significant impact of economic capacity on service exchange outcomes.
