Critics of modern macroeconomics often raise concerns about unwarranted welfare conclusions and data mining. This paper illustrates these concerns with a thought experiment, based on the debate in environmental economics about the appropriate discount rate in climate change analyses: I set up an...

The financial and economic crisis brings to a reconsideration of macroeconomics: as it happened in the past, after the Great Crash of 1929 as well as after the Second World War and after the collapse of the Bretton Woods system in 1971 and the subsequent oil crisis. A brief critical survey of...

The DSGE models are based on hypotheses that have the effect of excluding the possibility of severe financial and economic crises with the consequent policy implications going in the laissez-faire direction. The hypothesized unique and stable equilibrium in combination with rational expectations...

Solow has repeatedly called for the development of models that combine equilibrium and out-of equilibrium outcomes or what he called a macro-economics of the medium-run. This paper recounts the history of Solow's different attempts to address this issue. It starts in early 1950s when Solow...

Robert Solow has criticized our 2006 Journal of Economic Perspectives essay describing Modern Macroeconomics in Practice. Solow eloquently voices the commonly heard complaint that too much macroeconomic work today starts with a model with a single type of agent. We argue that modern...
