We find that a stable interior solution \u2013 that is, a Pasinetti equilibrium \u2013 is the most likely outcome, while the corner solutions of dual and anti-dual equilibria \u2013 both the euthanasia and the triumph of the rentier \u2013 are special cases of a standard Bhaduri-Marglin model. Endogenizing the profit share yields a two-dimensional dynamic system of the wealth concentration and the profit share, which is stable for a wide range of parameter values, as long as the concentration of wealth is not unrealistically low. An interior Pasinetti equilibrium thus remains the most likely outcome. However, for certain parameter combinations, the system may move onto an explosive trajectory with an ever-increasing concentration of wealth and income in the hands of capitalists. Numerically illustrating the results of the analytical model shows that endogenizing the profit share leads to a more unequal wealth distribution, and a negative feedback effect between high wealth inequality, a high profit share, and growth.","onlinedate":"2026-07-30 02:00:00","lang":"English","publication_series":"","publication_date":"20260730","publication_date_year":"","publication_date_full":true,"publication_num_pages":"","keywords":"[\"Wealth distribution\",\"Post-Keynesian model\",\"Aggragate demand\",\"Pasinetti\",\"Profit rate\"]","jelcodes":"[\"B22\",\"D31\",\"D33\",\"E12\",\"E21\",\"E64\"]","related_publications":"[]","pdf":null,"zip":null,"link":"https:\/\/doi.org\/10.1080\/01603477.2026.2622679","monthly_report":false,"monthly_report_main":false,"monthly_report_volume":"49","monthly_report_pages":"351-371","monthly_report_pages_sort":"351","issue":"2","journal":"Journal of Post Keynesian Economics","publisher":"","invisible":false,"external":true,"embargo_date":null,"types":[83083],"research_groups":[3500],"collaboration":"","persons":[3567,17197],"persons_data":"[{\"personId\":3567,\"personName\":\"Stefan Ederer\",\"organisationNames\":[]},{\"personId\":17197,\"personName\":\"Miriam Rehm\",\"organisationNames\":[\"UDE\"]}]","clients":[],"subclients":[],"partners":[],"topics":[],"host_publication_title":"","host_publication_subtitle":"","place_of_publication":"","host_publication_editors":"[]","type_description":"","output_media":"","chapter":"","article_number":"","citations":"","scientific_assistance":"[]","scientific_review":"[]","version":"","release_date":null,"expiration_date":null,"surveyor":"","research_assistance":"","edv":"","additional_info_de":"","additional_info_en":""},"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v28.3 (Yoast SEO v28.3) -
