Final answer:
Alice is typically expected to do 2 to 3 times more housework than Arthur. In the roommate scenario, assigning dishwashing to roommates is more time-efficient. However, efficiency differences can lead to unfair labor divisions, similar to trade imbalances in economic relations.
Step-by-step explanation:
If Alice and Arthur are a typical married couple who both work full-time, compared to Arthur, Alice will do 2 to 3 times more of the daily housework. Studies have shown that despite both partners working full-time, women are far more likely than men to engage in a greater share of household chores. This is a reflection of traditional gender roles that often persist in many societies, where housework and caretaking are commonly associated with female responsibilities.
When it comes to the roommate scenario in Washington, D.C., if you are 70% faster at dishes and 10% faster with vacuuming, you would want to assign the dishwashing to your roommates to maximize your free time, as your relative speed advantage is greater with that task. However, being faster might lead to you doing more work if not properly balanced with your roommates' contributions, which can create resentment or unfair divides in labor. This situation is analogous to trade relations, where countries that are more efficient at producing certain goods will focus on those, leading to comparative advantages and potential imbalances in trade relationships if not managed well.
