The question that need to be answered is this :
How does economics perspective or economic way of thinking relate to purposeful behavior, rational self-interest and marginal analysis?
also you need to respond to 3 students and this is their answers :
Economic perspective views institutions and individuals making rational decisions through perspective and strategy through comparisons of marginal benefit and marginal costs of their actions. Therefore economic perspective allows marginal analysis. This serves as a benefit when purposeful behavior has an influence upon opportunity cost. Lastly, rational self interest refers to the actions that elicit most personal belief.
It seems to me that we as humans use different approaches to achieve an economical way of thinking. This can be in the form of purposeful behavior where we conceptualize our utility before we make a decision. In addition, we use marginal analysis to weigh our options before making decisions. These two things combined, lead us to our impression of what our perspective is in economics. Ultimately, we all look at how things will benefit us in the short or long term. This in turn is our way of thinking and how it directly relates to economics in society.
Economic perspective is a viewpoint that envisions individuals and institutions making rational decisions by comparing the marginal benefits and marginal costs associated with their actions. By using the economic perspective, individuals are able to weigh marginal costs and benefits. Furthermore, purpose behavior has an influence upon opportunity cost.
Also, rational self-interest refers to the actions that elicit most personal belief.
