We investigate the effect of the regime-switching transaction costs and dividends on liquidity premium and investor’s optimal strategy. With reasonably calibrated parameters, we show that counter-cyclical transaction costs substantially raise liquidity premium while procyclical dividends...

This paper investigates robust consumption and portfolio rules for an Epstein-Zin type investor who concerns about model misspecifiation. Different from Maenhout (2004), we employ a new state variable, continuation entropy, as a measure of the magnitude of the investor's ambiguity aversion...

We investigate the effect of the regime-switching transaction costs and dividends on liquidity premium and investor's optimal strategy. With reasonably calibrated parameters, we show that counter-cyclical transaction costs substantially raise liquidity premium while pro-cyclical dividends...

We find a closed-form formula for valuing a time-switch option where its underlying asset is affected by a stochastically changing market environment, and apply it to the valuation of other qualitative options such as corridor options and options in foreign exchange markets. The stochastic...

We present an approach for pricing American put options with a regime-switching volatility. Our method reveals that the option price can be expressed as the sum of two components: the price of a European put option and the premium associated with the early exercise privilege. Our analysis...

This paper investigates an Epstein-Zin type investors' optimal consumption and portfolio choice problem in the presence of transaction costs and liquidation shocks. We model the liquidation shocks as a Poisson process, which enforces the representative investors to liquidate their wealth in an...

This paper investigates the optimal retirement of an individual in the presence of involuntary unemployment risks and borrowing constraints in a complete market with frictions. We use an intensity model and loading factors to illustrate the involuntary unemployment risks and frictions in...

We introduce a simple iterative method to determine the optimal exercise boundary for American options, allowing us to compute the values of American options and their Greeks quickly and accurately. Following Little, Pant and Hou's idea (2000), we derive a new equation for the optimal exercise...
