I show in a setting of a buyer and seller with the same preferences trading two related assets so as to share volatility risk that illiquidity and virtually all impediments to trade cannot be priced in the absence of excess short-selling costs. This is because the buyer values the asset at the...

We show in a fairly general setting of a buyer and seller with the same preferences trading two related assets so as to share volatility risk that illiquidity and virtually all impediments to trade cannot be priced. This is because the buying and selling counterparties must both be optimizing....

The paper is about pension fund problems where an agent pays an amount x0 to the fund manager and is repaid, after time T, a lump sum x(T). Such problems admit an analytical solution for specific, rather unrealistic formulations. Several practical pension fund problems are converted in the paper...

Adding a motivation for trading due to endowment differences to standard asset pricing assumptions, we investigate the impact of illiquidity due to small numbers of participants. We calibrate to observed activity levels, returns, transaction costs and volatility in equity markets. We show that,...

Following Constantinides' (1986) seminal approach and introducing transaction costs in the Pagano (1989) model, conventional CARA investors with heterogeneous endowments trade to construct optimal portfolios. We calibrate to the 1896-1994 equity and bond markets to show that gains from trade are...

This paper establishes a general analytical framework for continuous-time stochastic control problems for an ambiguity-averse agent (AAA) with time-inconsistent preference, where the control problems do not satisfy Bellman's principle of optimality. The AAA is concerned about model uncertainty...

This paper establishes a general analytical framework for the impulse controls of the diffusion processes driven by multidimensional G-Brownian motion. We propose new G-quasi-variational inequalities (G-QVI) and we provide a verification theorem to link a classical (smooth) solution of the G-QVI...

This paper develops a general continuous-time framework for defining optimal corporate pension policy. Interactions between the firm's optimal investment and financing policies and the defined benefit pension plan optimal portfolio strategy are studied. We prove that the three decision rules are...

A healthy financial system encourages the efficient allocation of capital and risk. The collapse of the house price bubble led to the financial crisis that started in 2007. There is a large empirical literature concerning the relation between asset price bubbles and financial crises. I evaluate...
