Ghana is presented as a central example of the limits of the “ignorance hypothesis”: the claim that poverty results because leaders do not know which policies promote prosperity. The country’s post-independence decline is instead traced to political incentives. Under Kwame Nkrumah and Kofi Busia, policies that damaged economic performance could still serve the purpose of maintaining political support; Busia’s attempt to change course ended in his overthrow.

Independence and the Limits of Policy Knowledge

After independence from Britain, Ghana entered a sustained period of economic decline. The account considers whether this trajectory reflected ignorance, but points to evidence that Nkrumah’s government had access to informed economic advice. Tony Killick, a British economist working as a government adviser, documented the problems with the state’s industrial projects. Sir Arthur Lewis, too, had advised the government, and the book says that he and other advisers knew the policies were poor ones.

The contrast between policy knowledge and policy choice is crucial. Ghana’s difficulties are not presented as the accidental result of leaders who simply lacked information about economic consequences. Rather, the decisions reflected the political uses of state resources and the incentives facing those in power.

Projects and Political Support under Nkrumah

Nkrumah’s industrial policy included projects whose design made little economic sense. One footwear factory was intended to draw on a chain of production and transport stretching across the country: hides would travel more than 500 miles from a northern meat factory to a tannery in the south, then the leather would be sent about 200 miles north to a footwear factory in Kumasi. Since the main market for shoes was around Accra, the finished goods would then travel another 200 miles back south. Killick described the factory’s location as undermining its viability.

The footwear project was not an isolated mistake. A mango-canning plant was located in an area that did not grow mangos, and its planned output exceeded total world demand. These examples make the argument concrete: apparently irrational economic development did not necessarily indicate that officials could not recognize the problems. The projects formed part of a political system in which economic policy helped Nkrumah buy support and sustain an undemocratic regime.

Busia’s Political Constraints

Kofi Busia came to power in 1969 as leader of a democratic government and an opponent of Nkrumah. Yet he faced many of the same political constraints. Like his predecessor, he pursued unsustainable economic expansion and maintained price controls through marketing boards, alongside an overvalued exchange rate. The policies helped transfer resources to politically powerful constituencies, including urban groups whose continued support mattered to the government.

Price controls kept food cheap for urban consumers by squeezing agriculture, while also generating revenue for government spending. Their political usefulness did not make them sustainable: Ghana soon faced repeated balance-of-payments crises and shortages of foreign exchange. The resulting conflict was not simply a matter of choosing between good and bad technical advice; it concerned who would bear the costs of changing a policy that benefited influential groups.

Devaluation and Overthrow

On December 27, 1971, Busia signed an agreement with the International Monetary Fund that included a massive currency devaluation. The IMF, the World Bank, and the wider international community pressed him to carry out the agreement’s reforms. But Busia understood that devaluation was a political gamble, even though the international institutions did not appreciate the danger he faced.

The immediate response was unrest in Accra. Rioting and discontent mounted until the military overthrew Busia, led by Lieutenant Colonel Acheampong. Acheampong immediately reversed the devaluation. The sequence shows how a reform intended to address economic crisis could threaten the political position of a government, and how the successor regime could undo it.

What Ghana Shows about Poverty

Ghana’s experience challenges the idea that prosperity can be engineered merely by giving rulers better advice or persuading them of sound economics. Busia’s case, in particular, shows that a leader may understand the consequences of a policy and still confront incentives that make reform dangerous. The decisive obstacles, in this account, are the incentives and constraints created by political and economic institutions, not simply a shortage of expertise.

The example also clarifies why the same country can experience damaging policies under governments with different political character: Busia opposed Nkrumah and governed democratically, yet faced pressures that led him to use economic policy to satisfy powerful constituencies. Ghana’s post-independence trajectory is therefore used not as a story of isolated administrative errors, but as evidence that political survival and economic welfare can pull in different directions.
