Discussion Time (Aim to be wrong!)
What evidence is needed
for the Political Agency Model to explain
No term limit for any political offices in Japan
Term limit for LDP President is de facto non-binding
as most presidents resign within 2 years (Wikipedia)
cf.
Argument against term limits in Japan: "Unconstitutional"
"the inalienable right to choose their public officials and to dismiss them"
Article 15
Article 22
Freedom of occupation
Motivation:
US: Term limit for President and two-thirds of State Governors
Latin America and Africa
Term limits for presidents were introduced when democratized
cf. China:
de facto term limit (10 years)
Motivation:
21 US states introduced
term limits for legislators
by referendum in the '90s
Source: Table 1.1 of Carey et al. (2000)
Motivation:
Many people in Africa support
term limits for their president
(surveyed in 2011-2013)
Source: Figure 1 of Dulani (2015)
Motivation:
The political agency model in the last lecture predicts otherwise
We've also seen supporting evidence from Brazil
This lecture extends the political agency model to show...
Term limits allow politicians to pick a good policy
(e.g. environment protection)
under a certain circumstances
For some policies, not every citizen cares about them
e.g. Policies for environment protection
Politicians act on such policies when electoral competition is fierce
Votes from minority groups count in a tight race
If so, term limits reduce such incentives of politicians, leading to:
No environment protection if minority groups are green
Environment protection if minority groups are brown
Citizens
Politicians
Incumbent
(chooses a policy in period 1 and, if re-elected, in period 2)
Opposition candidate
(chooses a policy in period 2 if defeating the incumbent)
A small fraction of citizens only care about environment policy
The rest of citizens: indifferent about environment policy
Two types: Green & Brown
Green
in favour of environment protection
Brown
against environment protection
A small fraction of citizens only care about environment policy
Environment protection
Preferred by some citizens, but not by every citizen
Two types: Green & Brown
Green
in favour of environment protection
Brown
against environment protection
Both types want to stay in office (for prestige etc.)
Citizens do not know each politician's type
Expect a politician to be green with probability P
Citizens observe policy choice in period 1
e.g. through mass media
This part of the model is the same as in the previous lecture
Step 1: Period 1 Policy-making
Step 2: Election
The incumbent chooses a policy
Citizens vote for the incumbent or for the opposition
Step 3: Period 2 Policy-making
Winner of the election chooses a policy
This part of the model is the same as in the previous lecture
Green politician
Protect environment
Brown politician
Forget about environment
Green citizens want a green politician to be in office in period 2
Brown citizens want a brown politician to be in office in period 2

It's NOT necessarily desirable
to make policy-maker responsive to voters
Elections backfire when
policy-makers have a better idea of desirable policies for society
To seek re-election, policy-makers will choose
a policy that voters believe is correct.
e.g. Green politician vs Brown citizens
e.g. Green politician doesn't protect environment to be re-elected

When citizens know which policy is bad (e.g. corruption)
Term limits allow politicians
to choose bad policy
When citizens DO NOT know which policy is bad (e.g. brown citizens)
Term limits allow well-informed politicians (e.g. green politicians)
not to choose what citizens believe is good
within the framework of the political agency model
Citizens observe
incumbent's performance
before election
Better-than-expected
performance
Re-election
of incumbent
Incumbent delivers
what citizens need
State governments in India
are responsible for
Distribution of foods, drinking water, medicine, clothes, housing
Repairing damaged properties
Monitoring food production and impending disasters
Political Agency Model predicts:
More media penetration
More relief provided by state government
When famine/disaster strikes
When famine/disaster strikes
More media penetration
More relief provided by state government
grain production
flood damage
newspaper circulation per capita
Food distribution
Relief expenditure
10% drop in grain production
Food distribution is increased by
in states with median
newspaper circulation
in states with 75 percentile
newspaper circulation
1.0%
2.3%
Similar result for relief expenditure in response to flooding
Press freedom is key to make the government accountable
for issues such as disaster relief and corruption
So this world map
is really worrisome
