Modern Principles

Więcej o książce

Our goals were to create a modern and simpler approach to macroeconomics. We recognized the need to cover essential topics such as the Solow Model, the economics of ideas, Real Business Cycles, and New Keynesian economics. While many texts address economic growth, they often overlook the significance of ideas. Additionally, most do not provide a balanced view of Real Business Cycle and New Keynesian theories, often favoring one over the other. To reach a broader audience, we aimed to make the material more accessible, engaging, and intuitive. By distilling the Solow model to its core and offering multiple pathways through the content, we have made it suitable for all students. Our approach to business fluctuations is both simpler and more advanced, modeling fluctuations in the growth rate of output rather than the output level. This creates a seamless transition from growth theory to business fluctuations. We also unify Real Business Cycles and New Keynesian economics within a single dynamic AD-AS model. Furthermore, our text provides an in-depth analysis of monetary and fiscal policy responses to real and nominal shocks, unlike any other textbook. By integrating recent advances in macroeconomic thought throughout the text, we ensure comprehensive coverage of contemporary principles that macroeconomists utilize today.
