Unhappy News about Knut Wicksell
Along with Philip Wicksteed, the Swedish economist Knut Wicksell (1851-1926) constructed an elegant neoclassical model of factor-income distribution that has been remarkably enduring. I have long admired Wicksell and admit to feeling sad that the GEM Project’s generalized-exchange macro model …

The Curse of Market-Centricity
The GEM Blog’s basic argument with mainstream macroeconomists concerns their market-centricity. The case is multidimensional but, at its core, is rooted in three facts.
