Venezuela and Argentina are two South American countries that exemplify the continent's shift away from US influence. But in the last week, actions by both governments have been pounced on by critics as signs of weakness in their economies. From Wednesday, Venezuela's currency - the bolivar - will lose almost a third of its value on international markets, the fifth time it has been devalued since President Hugo Chavez came to power. And in Argentina, in an attempt to tame rising costs, last week President Cristina Kirchner's administration came to an agreement with supermarkets to temporarily freeze prices. So what is the state of two of South America's biggest economies? To discuss this, Inside Story Americas is joined by guests: Mark Weisbrot, the c-director of the Center for Economic and Policy Research in Washington; and Arturo Porzecanski, an international finance and Latin American economic analyst from the American University.
