In order to value non-market goods, economists estimate individuals’ willingness to pay (WTP) for these goods using revealed or stated preference methods. We compare these conventional approaches with subjective well-being (SWB), which is based on individuals’ ratings of their happiness or...

In this paper we provide a characterization of the welfare properties of rational expectations equilibria of economies in which, prior to trading, agents have some information over the realization of uncertainity. We study a model with asymmetrically informed agents, treating symmetric...

We study the relation between firm growth and managerial incentive provision under moral hazard when a long-lived firm is operated by a sequence of managers. In our model, firms replace their managers not only upon poor performance to provide incentives, but also when outside managers are at a...

This paper examines the choice of tools for managing a firm’s operational risks: cash reserves, insurance contracts, and financial assets under an optimal financing contract that solves moral hazard between insiders and outside investors. Risk management is valuable as it reduces the costs of...

Market liquidity is typically characterized by a number of ad hoc metrics, such as depth, volume, bid-ask spreads etc. No general coherent denition seems to exist, and few attempts have been made to justify the existing metrics on welfare grounds. In this paper we propose a welfare-based...

Following the framework of Cetin et al. (finance stoch. 8:311-341, 2004), we study the problem of super-replication in the presence of liquidity costs under additional restrictions on the gamma of the hedging strategies in a generalized black-scholes economy. We find that the minimal...

Market liquidity is typically characterized by a number of ad hoc metrics, such as depth (or market impact), volume, intermediation costs (such as breadth) etc. No general coherent denition seems to exist, and few attempts have been made to justify the existing metrics on welfare grounds. In...

A substantial literature addresses the negative eect on welfare of the release of information in a competitive market economy. We show that the value of information in this setting is typically positive if asset markets are suciently incomplete. More specically, for any competitive equilibrium...
