A Business Cycle Model with Neuroeconomic Foundations
I present a new business cycle model in which decision-making follows a simple mental process motivated by neuroeconomics. Decision makers first compute the value of two different options and then choose the option that offers the highest value, but with errors. The resulting model is highly tractable and intuitive. A demand function in level replaces the traditional Euler equation. As a result, even liquid consumers can have a high marginal propensity to consume and the interest rate affects consumption through the cost of borrowing but not through intertemporal substitution. I discuss the implications for stimulus policies.
