Material vs. spiritual—A novel economics perspective on marriage and divorce

By dividing household-produced commodities into material and spiritual goods, and incorporating Maslow's psychological theory of motivation into this economic framework, I explore why individuals with different preferences choose different mates, and how the drive to enter marriage has changed as society becomes more developed. I then study the optimal effort for individuals to devote to marriage. I argue that divorce is mainly caused by the reduction of effort that couples devote to marriage, which might be a rational decision in response to changes in preferences, household productivity, and the opportunity cost of effort.
