Puzzle 1. China boomed for forty years while corruption stayed vast.
Puzzle 2. Hong Kong, next door, built famously clean government.
By the end of today you should be able to:
sort corruption into Ang’s four types; say which allow growth
explain how Hong Kong’s ICAC changed what people expected
criticise campaign enforcement using Chen and Kung’s princeling evidence
Part I — The puzzle: boom and bribes
The boom is not in doubt
What corruption is supposed to do to growth

Author’s illustration of the standard argument. No units; conceptual only.
The simple cross-country relationship is weak
Descriptive only. No controls for starting income, region or measurement error, and the base year is arbitrary. This motivates the puzzle; it does not test the corruption–growth hypothesis.
So what?
Counting corruption tells us how much. It does not tell us what kind.
Wedeman calls this China’s double paradox: growth and graft rose together
From 1978 to 2010 the economy grew roughly 9% a year
Corruption did not fall as markets deepened — it changed shape
Hong Kong ran the opposite experiment in the same region
Question 1. Who is involved — a clerk, or a powerful politician?
Question 2. What is the act — taking (one side loses), or trading (both expect to gain)?
Ang’s typology unbundles corruption by actor and by act.
Type
Who
The act
Likely effect on growth
Ang’s metaphor
Petty theft
Non-elites
Steals or extorts
Damaging
Toxic drug
Grand theft
Elites
Embezzles large sums
Highly damaging
Toxic drug
Speed money
Non-elites
Trades: pays to hurry
A tax on business
Painkiller
Access money
Elites
Trades: buys privilege
Can accompany investment
Steroid
Source: Ang (2020), ch. 1. Her claim is that the four types have different consequences — not that corruption causes growth.
Why access money can ride alongside growth

Author’s illustration of a mechanism Ang (2020) proposes, not an estimated causal effect. The loop is the point: the official profits from growth rather than from theft.
Steroids have side effects
Rewards flow to the connected, not to the most efficient
Land, property and local government debt inflate together
Inequality widens between insiders and everyone else
Officials rise and fall with their patrons — politics becomes risky
Growth becomes distorted as well as fast
Source: Ang (2020), ch. 1.
Measuring the four types separately
Transparency International’s index gives a country one score
One score cannot tell theft apart from access money
Ang’s index scores the four types separately
Method: an expert survey using short vignettes, piloted in 15 countries
China scores high on access money, lower on theft and speed money
Rich democracies also score high on access money, much of it legal
Source: Ang (2020), chs. 1–2. The index is a prototype measure, not an official statistic.
If it is legal, is it corruption?
Ang: China today rhymes with America’s Gilded Age
Lobbying, donations and the revolving door buy access too
In rich democracies most of that is perfectly legal
Legal influence and a brown envelope are not the same thing
Two minutes, hands up: should we define corruption by law, by behaviour, or by effect?

Exercise 1 — Sort the bribe
In pairs (5 minutes). Put each case in one of Ang’s four boxes, then answer the question below.
A customs officer keeps part of the duties she collects.
A restaurant pays a clerk so its licence arrives this week, not in three months.
A minister moves public pension money into a private account.
A developer funds a mayor’s flagship project; the city then rezones its land.
Question: which case is most compatible with rapid growth, and what does the economy pay for it later?
So what?
Ang offers one answer to Puzzle 1: what matters is the type of corruption, not the amount.
Access money offers an explanation for why the boom and the bribes could rise together. Whether it causes growth or merely travels alongside it is still contested.
And it says nothing about why Hong Kong, with the same starting problem, ended up somewhere else entirely.
Next: Melanie Manion on how clean government gets built.
Part III — Corruption by design (Manion)
Hong Kong before the ICAC
In the 1960s a bribe was the going rate for ordinary services
Police corruption was syndicated: organised, with known prices
1973: Chief Superintendent Peter Godber flees to Britain
Investigators found he held assets far beyond his lifetime salary
The police’s own anti-corruption branch could not touch him
February 1974: after the Blair-Kerr inquiry, the ICAC is created
Sources: Manion (2004), ch. 6; ICAC, official history of the commission.
An agency placed outside the police

Manion’s key idea: corruption is an equilibrium

Author’s illustration of Manion (2004). Beliefs about how common corruption is are what hold the loop together.

Independence. The Commissioner answers to the Governor, not the police
Permanence. A standing agency with its own staff and budget
Visibility. Senior officers prosecuted, publicly and repeatedly
A line under the past. Police protest in October 1977
Partial amnesty: offences committed before 1 January 1977 not pursued
Those already under investigation, wanted, or abroad were excluded
Sources: Manion (2004), ch. 6; ICAC official history. The amnesty closed the past once — not repeatedly.
Fifty years later, the gap is still visible
But was it really the ICAC?
The ICAC arrived in the middle of a much wider reform drive
Hong Kong was small, rich and urban, not a continent
Rising incomes made a civil-service job more costly to lose
Courts and newspapers operated with real independence
Manion shows the design was coherent; she cannot randomise it
Read Hong Kong as a strong case, not a controlled experiment
Sources: Manion (2004), ch. 6; ICAC official history. These rival explanations are not tested here — that is the point.
Exercise 2 — Would an ICAC work here?
In pairs (5 minutes), then two volunteers report back.
Your country announces a new anticorruption commission tomorrow.
Name one design feature from Hong Kong you would copy, and say what it changes.
Name one reason it might fail where you live.
Use these prompts: Who appoints the head? Who is allowed to be investigated? What do ordinary people currently expect when they need a permit?
So what?
Manion’s answer to Puzzle 2: Hong Kong did not out-punish corruption. It out-designed it.
That is her argument, and the evidence is a well-documented case rather than an experiment. What it establishes is a mechanism: expectations can be shifted deliberately, and kept credible.
Mainland China also punishes corruption — heavily, and very publicly.
Next: does a campaign do the same work as an institution?
Part IV — Campaigns and selectivity
Two designs, side by side
Two institutional designs for fighting corruption.
Design feature
Hong Kong ICAC (since 1974)
Mainland China (CCDI)
Who investigates
Standing agency outside the police
Party’s own discipline body
Answers to
Governor, later Chief Executive
Party leadership
Who can be targeted
Public and private sector
Party members and public employees
Rhythm of enforcement
Continuous, routine
Waves and campaigns
Main lever
Everyday expectations
Discipline and loyalty
Sources: Manion (2004); CCDI. Since 2018 a National Supervisory Commission extends the mainland’s reach to all public employees. Caution: these bodies sit inside very different political systems. This is a structured comparison, not a controlled experiment.
Xi’s campaign: real, and very large
Launched after the 18th Party Congress, November 2012
Slogan: “tigers and flies” — senior leaders and local officials alike
Zhou Yongkang, a former Politburo Standing Committee member, jailed for life
CCDI: 4.39 million cases investigated, 4.7 million people punished
That count runs from November 2012 to April 2022
Nobody disputes the scale. The question is what it changed.
Sources: CCDI press conference, June 2022 (as reported); court judgment in the Zhou Yongkang case, 11 June 2015.
Chen and Kung: land as a measuring rod
In China, local governments are the only legal seller of urban land
Every sale leaves a record: plot, price, buyer
Chen and Kung link buying firms to the families of Politburo members
Such firms are known as “princelings”
Over one million transactions, 2004–2016
Favouritism turns up directly in the price — nobody has to confess
Source: Chen and Kung (2019), Quarterly Journal of Economics. Prices are recorded by the state, not self-reported in a survey.
What a political connection was worth
Enforcement that is real, and also selective
Discounts shrank where the campaign landed: 31.5% to 42.6% less corruption
“Where it landed” means provinces inspected, or given a new party secretary
Before 2012, granting discounts paid: those secretaries rose faster
Chen and Kung estimate 23.4% higher odds of national promotion
The campaign closed that route to promotion
Enforcement was genuine — and targeted by the centre, not universal
Source: Chen and Kung (2019), Quarterly Journal of Economics, 134(1), 185–226.
So what? Five things to take away
Ask what kind of corruption a country has, not only how much
Access money can ride alongside growth — and store up risk
Theft and extortion are generally far more damaging to investment
Hong Kong worked by changing expectations, not by punishing harder
A campaign punishes; a credible institution changes what people believe
The exam-ready sentence: type of corruption and credibility of enforcement matter more than raw quantity.
What we still don’t know
Does access money cause growth, or merely travel alongside it?
Would an ICAC work without Hong Kong’s wider political setting?
When does a campaign become an institution rather than a purge?
Where is the line between access money and lawful political influence?
Each of these is a live research question. None of today’s three authors settles it.
Bring one of them to Thursday’s discussion with an argument, not just an opinion.
