Krugman sobre la Trampa de la Liquidez

Estimados
Paul Krugman, Premio Nóbel de economía dedica una buena parte de su tiempo a escribir sobre la trampa de la liquidez en su blog (que ustedes pueden encontrar en los blogs de economía a la derecha). Les recomiendo que entren y escriban "liquidity trap" en el buscador del blog de PK.
De todos modos les adjunto algunos links.
