After winning the election, the Mugabe ZANU–PF government re-instituted one party rule, doubled the civil service and, according to The Economist, embarked on "misrule and dazzling corruption". A 2017 study conducted by the Institute for Security Studies (ISS) concluded that due to the deterioration of government and the economy "the government encourages corruption to make up for its inability to fund its own institutions" with widespread and informal police roadblocks to issue fines to travellers being one manifestation of this. On 22 October 2015, president Robert Mugabe was awarded the Confucius Peace Prize, a Chinese alternative to the Nobel Peace Prize for his commitment to the nation's political and economic order. In July 2016 nationwide protests took place regarding the economic collapse in the country, and the finance minister admitted "Right now we literally have nothing."

If this rate of growth had been maintained for the next 37 years, Zimbabwe would have in 2016 a GDP of US$52 billion. Instead it had a formal sector GDP of only US$14 billion, a cost of US$38 billion in lost growth. The population growth in 1980 was among the
