Economist and president of the Earth Institute at Columbia University, Jeffrey Sachs is optimistic about Barack Obama's second term in office. He sees the president's strengthened political position as an opportunity to address what he believes are structural problems with the US economy. He tells John McDermott, comment editor, how the administration must go beyond Keynesian policies and reach out to local politicians to bridge bipartisan gaps.
