Household Portfolios in a Secular Stagnation World
: Evidence from Japan
March 28, 2016
We document low stock market participation rates and high proportions of money in Japanese household portfolios. To replicate these facts, we introduce a money demand motive in a life-cycle portfolio choice model and calibrate the model's structural parameters to match Japanese household financial data. Using counterfactual analysis we find that low expected stock returns, low expected inflation and high fixed costs of stock market participation are the main determinants of Japanese household portfolios.
