Costa Rica's central government offers tax exemptions for those willing to invest in the country. Several global high-tech corporations have already started developing in the area and are exporting goods, including Intel, GlaxoSmithKline, and Procter & Gamble. Pharmaceuticals, financial outsourcing, software development, and ecotourism have become the prime industries in Costa Rica's economy. High levels of education among its residents make the country an attractive investing location. Since 1999, tourism earns more foreign exchange than the combined exports of the country's three main cash crops: bananas, pineapples and coffee.
