Econ midterm
Which of the following statements is correct?

Figure 5.4 shows Angela and Bruno's feasible frontier, and Angela's biological survival constraint. Based on this figure, which of the following is correct?
A new technology that boosted grain production would result in a bigger technically feasible set.
According to the Great Economists box in Section 1.3 of The Economy, which of the following statements regarding Adam Smith are correct
Adam Smith claimed that coordination among large number of economic actors (producers, transporters, sellers, consumers), often unknown to each other, might spontaneously arise without any person or institution consciously attempting to create or maintain it. Adam Smith believed in the role of the government to improve societal welfare.
Figure 5.8 shows the Pareto efficiency curve CD for the interaction between Angela and Bruno. Which of the following statements is correct?
Angela's marginal rate of substitution is equal to the marginal rate of transformation at all points on the Pareto efficiency curve.
In Figure 5.10, Angela and Bruno are at allocation F, where she receives 3 bushels of grain for 4 hours of work. From the figure, we can conclude that:
Any point in the area between G, H and F would be a Pareto improvement.
In Figure 5.9, D and F are the outcomes before and after the introduction of a new law that limits Angela's work time to four hours a day while requiring a minimum pay of 4.5 bushels. Based on this information, which of the following statements are correct?
Both Angela and Bruno receive economic rents at F. As a result of the new law, Bruno has less bargaining power.

The following figure shows a model of free time and consumption per day across countries in 2013. Assume that the nationals of the US and Turkey have the same preferences (the same set of indifference curves) and those of Mexico and Netherlands have the same preferences. From the information given, we can conclude that:
For Turkish nationals, the income and substitution effects roughly cancel each other out if their wage level is increased to that of the US.

An individual's well-being can be partly measured by
Goods and services that are produced within the household, such as meals and childcare. Her disposable income. The quality of her social and physical environment, such as friendship and clean air. Goods and services that are provided by the government, such as healthcare and education.
Which of the following leads to higher GDP?

Profits are claimed by the capitalists. It allows failing firms to go bankrupt
According to Elinor Ostrom, which of the following statements about the problem of ?tragedy of the commons? are correct?
Social norms can be drawn on to enforce sustainable resources, although it does not always succeed. Even if all individuals were completely selfish, repeated interactions would definitely result in cooperative outcomes. Individuals care about trust and reciprocity. Agreements for cooperation must be enforced by governments
The figure below shows Angela and Bruno's feasible frontier, Angela's biological survival constraint, and her reservation indifference curve, when Angela would accept any offers strictly better than her reservation position of no work and 2 bushels of survival rations from the government. Now consider the case where Angela cares about the fairness of distribution, such that she can reject an offer that she considers unfair and choose not to work. In such a case Bruno will also receive no income. Then, compared to the reservation indifference curve depicted above, Angela's new reservation indifference curve is:
Steeper and goes through Z.
The effect that is only due to changes in the price or opportunity cost, given the new level of utility.

The following diagram shows the Lorenz curves for the factor (the market) income and the disposable income of the Netherlands in 2010.

The economically feasible set can be an empty set.
The following diagram shows a farmer?s choice between free time and grain before (A) and after (B) an improvement in technology. Based on this information, which of the following statements are correct?
The farmer may choose a point on either side of B after the technology improvement. If the MRS of the indifference curve at B is larger than the MRS of the indifference curve at A, then this gives the farmer an incentive to take more free time after the technology improvement.
In a simultaneous one-shot prisoners' dilemma game with completely self-interested players:
The players' payoffs are lower in the dominant strategy equilibrium than in some other outcomes.

Which of the following statements regarding social preferences are correct?
They are the preferences of society as a whole. Altruism is an example of social preferences. An individual has social preferences if he does not care about the outcomes of others in society. ?Keeping up with the Joneses? is an example of behaviour that could be motivated by social preferences.

Figure 5.7a shows Angela and Bruno's feasible frontier, Angela's biological survival constraint and her reservation indifference curve. B is the outcome under coercion, while D is the outcome under voluntary exchange when Bruno makes a take-it-or-leave-it offer. Looking at this graph, we can conclude that:
With a take-it-or-leave-it offer, Bruno's economic rent is equal to the joint surplus.
The following is a plot of GDP per capita against average annual hours of free time per worker in different countries. Which of the following statements is correct?
Workers in the US and Turkey enjoy a similar amount of free time despite the huge disparity of income.
Currently, you work for 40 hours per week for a wage of £20 an hour. Your free hours are defined as the number of hours per week not spent working, which in this case is (24 hours x 7 days) - 40 hours = 128 hours per week. Suppose now that your wage rate has increased by 25%. If you are happy to keep your total weekly income constant, then:
Your total number of free hours per week will increase by 6.25%.
In game theory, the strategy that will give a player the highest payoff, given the strategies that the other players select.
best response

dominant strategy
The out-of-pocket cost of an action, plus the opportunity cost.
economic cost

opportunity cost
The benefit to each player associated with the joint actions of all the players
payoffs
A game in which the payoffs in the dominant strategy equilibrium are lower for each player, and also lower in total, than if neither player played the dominant strategy.
prisoners' dilemma

simultaneous game
