been volatile, but exports of this tropical crop normally provided about half of the country's foreign currency earnings. Beginning in the 1960s, however, a number of factors combined to limit severely this vital source of national income. These factors included foreign competition (particularly from neighbouring Côte d'Ivoire), a lack of understanding of free-market forces (by the government in setting prices paid to farmers), accusations of bureaucratic incompetence in the Cocoa Marketing Board, and the smuggling of crops into Côte d'Ivoire. As a result, Ghana's income from cocoa exports continued to fall dramatically. Austerity measures imposed by the Busia administration alienated influential Farmers, who until then had been PP supporters. These measures were part of Busia's economic structural adjustment efforts to put the country on a sounder financial base. The austerity programs had been recommended by the International Monetary Fund. The recovery measures also severely affected the middle class and the salaried work force, both of which faced wage freezes, tax increases, currency devaluations, and rising import prices. These measures precipitated protests from the Trade Union Congress. In response, the government sent the army to occupy the trade union headquarters and to block strike actions—a situation that some perceived as negating the government's claim to be operating democratically. The army troops and officers upon whom Busia relied for support were themselves affected, both in their personal lives and in the tightening of the defence budget, by these same austerity measures. As the leader of the anti-Busia coup declared on 13 January 1972, even those amenities enjoyed by the army during the Nkrumah regime were no longer available. Knowing that austerity had alienated the officers, the Busia government began to change the leadership of the army's combat elements. This, however, was the last straw. Lieutenant Colonel Ignatius Kutu Acheampong, temporarily commanding the First Brigade around Accra, led a bloodless coup that ended the Second Republic. National Redemption Council years, 1972–1979 Despite its short existence, the Second Republic was significant in that the development problems the nation faced came clearly into focus. These included uneven distribution of investment funds and favouritism toward certain groups and regions. Furthermore, important questions about developmental priorities emerged. For example, was rural development more important than the needs of the urban population? Or, to what extent was the government to incur the cost of university education? And more important, was the public to be drawn into the debate
