Why does Jordi Galí use stylized models in macroeconomics?
My approach as a structural economist emphasizes the use of clear, stylized models with explicit microfoundations. This is crucial for isolating the essential mechanisms driving macroeconomic phenomena, such as inflation and business cycles. By capturing key frictions like sticky prices and imperfect competition, these models provide a tractable framework for deriving analytical results. These results are then empirically tested using advanced econometric techniques, allowing us to confront theory with data and refine our understanding of the economy.
