  • Public Finance Lunch
  • October 30th, 2006

Overview
  • Motivating Topic The Missing Girls of China
    India
  • Background (focus on China)
  • Theoretical Model of Sex Selection Decision
  • Empirical Results
  • Policy Implications

One Child Policy

Section 1Fertility Policy in China
5
Fertility Policy in China
  • Pronatalist Policy 1949-1969
  • Two is Enough 1970-1979
  • Strict One Child Policy 1979-1983
  • Opening Small Holes, Close Large Ones 1984
  • Today Federalism

6
Fertility Policy in China
  • One Child Policy (35)
  • Urban residents, population near cities
  • 1.5 Child Policy (54)
  • Rural areas in inner provinces
  • Two Child Policy (10)
  • Rural areas in outer provinces
  • Three Child Policy (1)
  • Residents in very remote areas

Enforcement of Policy
First, we employ reasoning and education. Then,
we order a pregnancy fine and forced abortion.
For persons with above-quota births, we mete out
fines for those with many births, we confiscate
land and revoke household registration.

Sex Ratio

Q Should we think the cost of sex ratio
distortion is large?
14
Welfare Implications of Sex Selection
  • Dead Weight Loss in Marriage market
  • Among those who marry, women do relatively better
    and men do relatively worse. ZERO SUM
  • Increase in unmatched men imposes DWL
  • 23 million boys will not find Chinese brides
  • The guang guan Bare Branches
  • It wont fix itself!
  • Parents prefer an unmarried son to a married
    daughter.

Poston and Glover (2000)
15
Policy Current Proposed
  • Care for Girls campaign
  • Outlawing sex selection
  • Black Market for ultrasound
  • 3. Raise fertility limits???

Not Working
Price is 6-40 - Cheap
Original Problem!
4. Social Insurance for those fail to have a son
Thought experiment. If sons provide a dollar
value ?, one could tax those with a son ½ of ?
and reward those with daughters with ½ of ?

Features of the Model
  • Mothers place a value of ? on a first-born son.
  • Mothers want a son but face a fertility limit
  • that is enforced by dollar fines F1 and F2
  • for 1st and 2nd extra children. (2nd and 3rd
    Births)
  • 3. Mothers have access to a sex selection
    technology that is 100 effective and costs A.
  • 4. Mothers with a son never have another child.

4th Decision Abort or Stop
  • Abortion Payoff
  • Dont Abort Payoff

21
Intuition of 4th Decision
  • Abortion when value of a son is large relative
    to cost of abortion

3rd Decision Kid or Stop
  • Have a kid
  • Dont

Payoff of Abortion
Payoff of Stoppingexp(0)
24
Intuition of 3rd Decision
  • Have a kid when son preference is large relative
    to fine.
  • Have a kid when payoff in round 4 is large, which
    happens when son preference exceeds abortion cost

2nd Decision Abort or Keep
  • Abort
  • Keep

Payoff of 3rd Kid
Payoff of Stoppingexp(0)
27
Intuition of 2nd Decision
  • Abort when ? A gtgt E(V3)
  • E(V3) .51? F2 .49 E(V4)
  • Abort if third fine is large!

Extreme case Mother will never die without son.
Now or Later scenario ? Abort when F2 gt .49A

Payoff of Stopping

Heterogeneity
Maximum Likelihood Estimation Choose optimal
?1- ?5 given observed data
31
Basic Intuition of the Model
  • Abort 3rd Girl if Value of Son Exceeds Marginal
    Cost (?gtA)
  • Have 3rd Child if Value of Natural or Augmented
    chance of having a son exceeds the fine.
  • Implication Those who wont abort more likely
    to stop.
  • Abort 2nd Girl to Avoid a 3rd Child! Fine is
    expensive.
  • Simple Case For mothers who know they will
    abort eventually, the decision is Now or
    Later.
  • When the (3rd Child Fine gt 49 of Abortion
    cost),
  • abort the second child.

Policy Simulations
  • Q What if you could reduce ? by subsidizing
    daughters? How much would that cost?
  • A A lot. But as I will show, it will accomplish
    the dual objective of lowering fertility and
    reducing the sex ratio.

36
Lower Female Deficit
Declining Efficiency
Indirect cost of Policy
Direct cost of Policy
Falling Fertility
37
Key Lessons
  • Cautionary tale of policy with unanticipated
    consequences
  • This problem is around the horizon in India. Fix
    it now.
  • Only way to address dual concern of fertility
    rates and sex ratio is by reducing the demand for
    sons.
