First ,Ghana’s shift to services sectors only marginallycontributes to labor productivity growth.Second,concentration of economic activity in natural resourcesincrease economic volatility and complicatemacro-management.The provision of basic public servicesremains a challenge according to private sector executivesurveys.Economic diversification is a key element ofeconomic development in which a country moves to a morediverse production and trade structure.
