现代微观经济学的研究趋势是“向其他区域扩张”，比如和社会学交叉的家庭经济学，以家庭社会行为为研究对象，分析婚姻、生育、就业等活动中的经济学原理。家庭经济学向人们揭示了看待家庭活动的崭新视角。下面这篇家庭经济学代写范文是Essayphd团队临危受命，在短时间内加急完成的。虽然家庭经济学是微观经济学中比较冷门的分支，但是万变不离其宗，Essayphd依然出色的完成了客户的委托。

Question 1 Monogamy and polygamy

(a) (10 points) Suppose we have a society with Nm men and Nf women. Using the analysis of the monogamous marriage market from Chapter 3 (see slide 4 of the corresponding notes) where women supply themselves on the marriage market and men demand women as wives, show that if Nm > Nf , women will receive all the gains from marriage at the monogamous equilibrium point em.

(b) (10 points) Show that if Nm > Nf polygamy doesn't raise women's payoff from marriage. Why not?

(c) (20 points) Consider an economy with two types of men, type A and type B. All women are identical. Let MPA1f > MPA2f > MPA3f > MP1Bf > Zf >MPA4f > MPB2f , and 2NA m + NB m < Nf < 3NA m + NB m. What are the marriage market payoffs of each type of man and of women under monogamy? What are the marriage market payoffs of each type of man and of women under polygamy? (Use a graph it it helps.) Is polygamy likely to exist in this economy? Explain your reasoning why or why not.

(d) (10 points) Why is there less polygamy worldwide today than 300 years ago?

这篇家庭经济学代写范文主要分析的问题是在婚姻市场中，一夫多妻制和一夫一妻制的经济学原理。

家庭经济学代写Answer

家庭经济学代写As depicted in figure 1, the market equilibrium will happen at the intersection point ( ) of supply curve and demand curve. Only man will get married. All women will get an income of at the equilibrium point, thus they will receive all the gains from marriage (the gray striped area).

(b) Since , there are more men than women in the market, so no man would get a second wife even under polygamy. Therefore there will be man marrying one wife, while the rest ( ) men will be bachelor forever. This is the same situation with the case of monogamy. Women’s gain from the market will stay the same as depicted in the striped area of figure 1. Therefore, polygamy would not raise women’s payoff.

(c) Case of Monogamy: since the total number of women is larger than the total number of man( ), all men will get married with one wife. The supply and demand situation can be depicted in figure 2家庭经济学代写:

In the figure above, is the marginal product of first wife for type A man ( ); is the marginal product of first wife for type B man ( ). At the equilibrium point , women will get an income of , which is the same as their single output; type A man will get an income of ; type B man will get an income of . Therefore the type A man’s gain from marriage will be the green striped area; type B man’s gains from marriage will be the gray striped area. Women will be indifferent between marriage or single since their gains from marriage is zero.

从这篇家庭经济学代写范文中可以得出，在特定的市场条件下，一夫多妻制会有更佳的婚姻市场回报。但是随着生产力的发展，家庭产出的重心转移，男性表现出更高的生产效率，一夫一妻制逐渐取代了一夫多妻制成为社会的主流。
