Abstract

This paper studies coordination between firms in a multi-sectoral macroeconomic model with endogenous business cycles. Firms are both in competition and interdependent, and set their prices with a markup over unit costs. Markups are heterogeneous and evolve under market pressure. We observe a systematic coordination within firms in each sector, and between each sector. The resulting pattern of relative prices are consistent with the labor theory of value. Those emerging features are robust to technology shocks.
