Costa Rica's basically stable economy depends on tourism, agriculture, and electronics exports. Poverty has been substantially reduced over the past 15 years, and a strong social safety net has been put into place. Foreign investors remain attracted by the country's political stability and high education levels, and tourism continues to bring in foreign exchange. Low prices for coffee and bananas have hurt the agricultural sector. The government continues to grapple with its large deficit and massive internal debt. The reduction of inflation remains a difficult problem because of rises in the price of imports, labor market rigidities, and fiscal deficits. Costa Rica recently concluded negotiations to participate in the US - Central American Free Trade Agreement, which, if ratified by the Costa Rican Legislature, would result in economic reforms and an improved investment climate.
