This paper presents a theory of disclosure in a market where investors have heterogeneous beliefs and face short-sale constraints. Assets trade above fundamentals reflecting the value of the option to sell to more optimistic investors in the future. The initial seller has an incentive to commit to an imprecise disclosure policy, despite the negative effect this has on the fundamental value of the asset, in order to increase the potential for disagreement and hence the magnitude of the speculative premium.

Ethics in business is a major topic both in the social sciences and in business itself. Anthropologists, long attendant to the intersection of ethics and practice, are particularly well suited to offer vital insights on the subject. This timely collection considers a range of ethical issues in business through the examination of anthropologically informed theory and case examples.

We demonstrate a novel link between relationship-specific investments and risk in a setting where division managers operate under moral hazard and collaborate on joint projects. Specific investments increase efficiency at the margin. This expands the scale of operations and thereby adds to the compensation risk borne by the managers. Accounting for this investment/risk link overturns key findings from prior incomplete contracting studies.

Recent bank regulations have imposed large compliance costs on banks of all sizes, and have increased the costs of borrowing to both consumers and companies. But in this summary of his recent book, the author argues that the problems with banking system regulation go well beyond the excessive costs. Indeed, Dodd-Frank and other post-crisis regulatory reforms have failed to address the major shortcomings that produced the crisis of 2007–2009. Most importantly, excessive housing finance risk was not dealt with adequately, and is already on the rise again.

Background and objectives research suggests that altering situation-specific evaluations of stress as challenging versus threatening can improve responses to stress. The aim of the current study was to explore whether cognitive, physiological and affective stress responses can be altered independent of situation-specific evaluations by changing individuals mindsets about the nature of stress in general. Using a design, we experimentally manipulated stress mindset using multi-media film clips orienting participants to either the enhancing or debilitating nature of stress.

We study a dynamic learning model in which heterogeneously connected Bayesian players choose between two activities: learning from one's own experience (work) or learning from the experience of others (search). Players who work produce an inflow of information which is local and dispersed around the society. Players who search, instead, aggregate the information produced by others and facilitate its diffusion, thereby transforming what inherently is a private good into information that everyone can access more easily.

We introduce a tractable dynamic monitoring technology into a continuous-time moral hazard problem and study the optimal long-term contract between principal and agent. Monitoring adds value by allowing the principal to reduce the intensity of performance-based incentives, reducing the likelihood of costly termination. We present a novel characterization of optimal dynamic incentive provision when performance-based incentives may decline continuously to zero. Termination happens in equilibrium only if its costs are relatively low.

We develop a tractable general equilibrium framework of housing and mortgage markets with aggregate and idiosyncratic risks, costly liquidity and strategic defaults, empirically relevant informational asymmetries, and endogenous mortgage design. We show that adverse selection plays an important role in shaping the form of an equilibrium contract. If borrowers' homeownership values are known, aggregate wages and house prices determine the optimal state-contingent mortgage payments, which efficiently reduces the costs of liquidity default.
