The value of house work


Generally, economists have applied the replacement cost (RC) method in valuing the work done by housewives. The replacement cost approach to the problem asks: “how much would it cost to replace the services of the housewife?” The idea being one could go into the market place, find the wage for nannies, cooks, maids, etc., then use these wages as the value of the housewife services.

As i last checked, some agencies are charging $8.5 per hour for housework.
Assuming this amount is the same for hiring a cook and for child care, and that a housewife will carry out these activities for 10 hours, we are looking at a cost of $85 per day.
Over the period of a year, the services contributed by a housewife adds up to a pricey sum of $31025 (85x365). In actual fact, the amount should be higher taking into consideration higher charges for weekends.
Ok, owe up those who thought that housework costs nothing!
So guys, time to show some appreciation to your wife or mum.... :-)

However, the fundamental problem with RC method is that it is based on market oriented economic theory, and as a result they ignore the institutional aspect of marriage. Marriage, as an institution, is designed to produce a set of goods that the market does not produce. Certainly some market goods get jointly produced in the marriage, but these are secondary to the main purpose of marriage. Marriage restricts the behavior of both the husband and wife such that they have an incentive over their life-cycle to cooperate in procreation and the successful rearing of the next generation. To confuse the value of a housewife with the services of domestic service misses the point entirely. The market based procedures are only crude, unreliable, and biased under-estimates of the true value of a housewife.

Marriage is a sharing arrangement. A husband does not hire his wife, nor does the wife hire her husband. When the marriage is doing well both benefit, and in hard times both suffer: “for better or for worse.” Some shares are better than others. A spouse who gets a small share of the pie has little incentive to work within the marriage. The gains from an increased share to this person will more than offset the disincentives caused by reducing the share to the other spouse. Economists have shown that for a given man and woman there is an “optimal share” which creates the best incentives for the husband and wife to contribute to the marriage.

Couples do not marry in a vacuum. Individuals compete with one another for mates. This competition for spouses, along with the optimal sharing rule above, forces people to marry individuals they expect will make an equal contribution to the marriage. A person will always do better marrying someone of equal quality and sharing equally, rather than marry someone with of a lower quality, even though their share is higher in the latter case. The result is that in equilibrium husbands match with wives who are expected to contribute equally over the life of the marriage.

Recognizing the incentives of sharing explains why full time working wives still tend to do more than half of the housework in a marriage. Women still earn 70% of men, on average. Since total contributions must be equal in successful marriages, women who contribute less market value to the marriage must contribute more household services.

If we accept the argument that individuals marry others of equal expected value, then we have a simple, but better, method of measuring the value of household services for marriages that remain intact. If a marriage is on-going, the partners must feel that on average they are getting out of the marriage what they are putting in, and that this marriage provides a higher value than marriages to other people. The condition for this is that the partners are making approximately equal contributions and are sharing 50-50. Thus, to determine the value of household services we need only look at the market earnings of the husband and adjust for the market earnings of the wife, and the household services of the husband. Or:

Value of housewife = Husband’s income – Wife’s income + value of husband’s household services

Suppose the wife does not work outside the home, and the husband never does any work around the house. Then the value of the wife’s household service is simply equal to the husband’s income. This methodology is not only easier than the standard ones, it is better in that it is a true measure of value, rather than just cost. It is better because it does not have any of the ad hoc aspects of the market measures since it relies on the revealed behavior of the individuals to assess their own value
