When investors have incomplete information, expected returns, as measured by an econometrician, deviate from those predicted by standard asset pricing models by including a term that is the product of the stock's idiosyncratic volatility and the investors' aggregated forecast errors. If...

Employees' incentive to invest in their task proficiency depends on the likelihood that they will execute the same tasks in the future. Changes in tasks can be warranted as a result of technological progress and changes in firm strategy as well as from fine-tuning job design and from monitoring...

Many basic economic theories with perfectly functioning markets do not predict the existence of the vast number of microenterprises readily observed across the world. We put forward a model that illuminates why financial and managerial capital constraints may impede experimentation, and thus...

We analyze social learning and innovation in an overlapping generations model in which available technologies have correlated payoffs. Each generation experiments within a set of policies whose payoffs are initially unknown and drawn from the path of a Brownian motion with drift. Marginal...

Firms spend substantial resources on marketing and selling. Interpreting this as evidence of frictions in product markets, which require firms to spend resources on customer acquisition, this paper develops a search theoretic model of firm dynamics in frictional product markets. Introducing...

Many basic economic theories with perfectly functioning markets do not predict the existence of the vast number of microenterprises readily observed across the world. We put forward a model that illuminates why financial and managerial capital constraints may impede experimentation, and thus...

We show how financial and managerial constraints impede experimentation and thus limit learning about the profitability of investments. Imperfect information about one's own type, but willingness to experiment to learn one's type, leads to short-run negative expected returns to investments, with...

This study examines various determinants of idiosyncratic risk from the perspective of un-diversified REIT investors, managers holding options, other option holders, and arbitrageurs. Since real estate investment trusts (REITs) enjoy a unique organizational structure and tax status, the relevant...

We analyze a general equilibrium model where production shocks are unobservable and there is structural uncertainty regarding investment risk because the volatility of the production shocks is unknown. Higher investment generally accelerates learning on the unknown parameter, but the dynamic...

This study aims to analyse the provisions of the Alternative Investment Fund Managers Directive of the European Parliament and of the Council (2011/61/EU) which pertain to its scope. It is divided into two Sections:(a) Section A offers an overview of the legal framework governing alternative...
