Asset Pricing with Idiosyncratic Shocks


Pithak Srisuksai and Vimut Vanitcharearntham


This study shows the relationship between idiosyncratic shocks and expected returns on stock regarding theoretical and empirical results. The dynamic stochastic general equilibrium is derived from idiosyncratic stochastic productivity level in production function of heterogenous firms to come up with a new asset pricing model. Given any state S, the main finding states that expected stock returns depends on the rate of time preference, depreciation rate, capital share, expected idiosyncratic productivity level at time t + 1,\ the percentage deviation of capital from steady state at time t + 1, and the percentage deviation of labor from steady state at time t + 1, In fact, expected idiosyncratic productivity level, expected capital, and expected labor are the determinant factors that affect on expected stock returns. Eventually, expected idiosyncratic stochastic productivity level is positively related to expected stock returns similar to expected labor. In contrast, expected capital has a negative effect on expected stock return
