The global financial crisis, which began in August 2007 and continues with no end in sight, has thrown macroeconomics into turmoil. This book challenges the current mainstream macroeconomic tradition, rejecting the view that whatever shock hits the economy, the response is an automatic and rapid move towards market equilibrium that pulls the economy out of any kind of difficult situation. Engaging with the structural problems of our times, especially in the context of the global financial crisis, the essays not just engage with Keynesian economics, but also adapt and go beyond it as per the requirements of present conditions. The essays apply the 'Keynesian spirit' to cover four broad areas: effective demand in the crisis, economic theory in the context of world recession, money and international liquidity, and finance and international economic disorder. Suggesting an alternative future of macroeconomics, this volume inspires and provokes new economic thinking that is needed for the world today.
