Disagreement about macroeconomic fundamentals accounts for only part of the disagreement about future interest rates, creating a ‘‘disagreement correlation’’ puzzle. This puzzle arises because standard equilibrium models with belief differences predict a strong link between asset return disagreement and fundamental disagreement, a link not supported by the data. We address this puzzle by introducing a model where disagreement about future demand for savings—driven by disagreement...

Survey-based excess stock return forecasts are procyclical, less volatile, and more persistent than countercyclical statistical forecasts. These patterns challenge rational representative-agent models. We show that they arise naturally in fully rational heterogeneous-belief models with speculative trade. Prices reflect the market view, a consumption and risk tolerance weighted belief of investors rather than the survey consensus views, which ignores gains from trade when aggregating beliefs. In...

We study a macro-finance model with entrepreneurs who have diverse views about the likelihood that their ideas will lead to successful innovations. These views and the resulting experimentation stimulate economic growth and overcome market failures that would otherwise occur in an equilibrium without this diversity. The resulting benefits for future generations come at the cost of higher wealth and consumption inequality because a few entrepreneurs...
