World economy, economics and economic policy: what emerges after the crisis?

The paper analyzes the current discussions on the state of economics with special focus on the interrelationships between key ideas of economic theories and real actions of economic policy in the course of the global economic crisis. The global economic crisis showed the limited ability of mainstream in economics to service the economic practice, and, therefore, the attention of researchers and economic policy-makers was drawn again to some alternative views in economics.
