The analysis of economic growth has developed rapidly in the last fifteen years and a command of its central ideas is now essential for all economists. This volume contains prestigious papers discussing recent work on economic growth from both theoretical and empirical points of view. The contributors cover topics such as technical progress, human capital, international trade, convergence, unemployment, and fiscal policy. A central question to which they return is whether steady state methodology is adequate on its own, or whether economists should pay more attention to transitional growth dynamics. All the papers have been selected to be accessible to the technically competent non-specialist economist.
