单选题
As my fine professor of economics Lowell Harriss used to tell us, economics is the study of the allocation of scarce goods and services. What could be scarcer or more precious than love? It is rare, hard to come by and often fragile.
My primary life study has been about love. Second comes economics, so here, in the form of a few rules, is a little amalgam (统一体) of the two fields: the economics of love.
In general, and with rare exceptions, the returns in love situations are roughly proportional to the amount of time and devotion invested. The amount of love you get from an investment in love is correlated, if only roughly, to the amount of yourself you invest in the relationship.
If you invest caring, patience and unselfishness, you get those things back.
High-quality bonds consistently yield more return than junk, and so it is with high-quality love. As for the returns on bonds, I know that my comment will come as a surprise to people who have been brainwashed into thinking that junk bonds are free money. They aren"t. The data from bond research, W. Braddock Hickman, shows that junk debt outperforms high quality only in rare situations, because of the default risk.
In love, the data is even clearer. Stay with high-quality human beings. And once you find that you are in a junk relationship, sell immediately. Junk situations can look appealing and seductive, but junk is junk. Be wary of it unless you control the market.
In every long-term romantic situation, returns are greater when there is a monopoly. If you have to share your love with others, if you have to compete even after a brief while with others, forget the whole thing. You want to have monopoly bonds with your long-term lover. At least most situations work out better this way.
The returns on your investment should at least equal the cost of the investment. If you are getting less back than you put in over a considerable period of time, back off.
To coin a phrase: Fall in love in haste, repent at leisure.
