…with two types of people, where asset price fluctuations are caused by random shocks to the price level that reallocate consumption across generations…. Asset prices are volatile and price-earnings ratios are persistent, even though there is no fundamental uncertainty and financial markets are sequentially complete. I show that the model can explain a substantial risk premium while generating smooth time series for consumption and financial assets across types. In my model, asset price fluctuations are Pareto inefficient and there is a role for treasury or central bank intervention to stabilize asset prices.

Must-Read: Roger E.A. Farmer: Global Sunspots and Asset Prices in a Monetary Economy: “A simple model in which asset price fluctuations are caused by sunspots…

…I construct global sunspot equilibria. My agents are expected utility maximizers with logarithmic utility functions, there are no fundamental shocks and markets are sequentially complete. Despite the simplicity of these assumptions, I am able to go a considerable way towards explaining features of asset pricing data that have presented an obstacle to previous models that adopted similar assumptions. My model generates volatile persistent swings in asset prices, a substantial term premium for long bonds and bursts of conditional volatility in rates of return.
