An overview of the post-colonial era, via Wikipedia:
Almost 70% of the Ivorian people are engaged in some form of agricultural activity. GDP per capita grew 82% in the 1960s, reaching a peak growth of 360% in the 1970s. But this proved unsustainable and it shrank by 28% in the 1980s and a further 22% in the 1990s.
Growth has been basically static since 2000, when the civil war broke out. The economy grew steadily (if unspectacularly) from 2008-2010, but shrank by 4.7% in 2011 as the civil war increased in intensity.
Growth accelerated rapidly in 2012 as the political situation stabilized. According a government spokesman in October 2012, the economy was expected to grow by 8.6% in 2012 and 9% in 2013. The government's proposed budget for 2013 was expected to be up by 17% over its 2012 budget.
The Cote d'Ivoire's main exports are cocoa, cashews, coffee, rubber and oil. Lots of other interesting facts in this Christian Science Monitor article.
