The foreign direct investments (FDI) spillovers are probably the most extensively analyzed channel of knowledge spillovers (the most important channel for the transfer of knowledge and technology to firms of the host country). Scholars as well as policy makers increasingly treat FDI spillovers...

Investment in physical capital at the micro level is infrequent and large, or lumpy. The most common explanation for this is that firms face non-convex physical adjustment costs. The model developed in this paper shows that information costs make investment lumpy at the micro level, even in the...

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...

Preferences of a Decision Maker define a valuation function on future uncertain payoffs. Consistency of this unconditional valuation function with valuation conditional on information arrivals is justified by a no Money Pump argument. A result on the updating of capacities is obtained in a...

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...

This paper considers the financing of a research project under uncertainty about the time of completion and the probability of eventual success.The uncertainty about future success gradually diminishes with the arrival of additional funding.The entrepreneur controls the funds and can divert...

Investment in physical capital at the micro level is infrequent and large, or lumpy. The most common explanation for this is that firms face non-convex physical adjustment costs. The model developed in this paper shows that information costs make investment lumpy at the micro level, even in the...

Recent history suggests that many boom-bust cycles are naturally driven by linkages between the credit market and asset prices. Additionally, new structured securities have been developed, e.g., MBS, CDOs, and CDS, which have acted as instruments of risk transfer. We show that there is a certain...

Multinational enterprises (MNEs) develop their networks of foreign affiliates gradually over time. Instead of exploring all profitable opportunities immediately, they first establish themselves in their home countries and then enter new markets stepwise. We argue that this behavior is driven by...

We develop a dynamic principal–agent model to show how imperfect public information and asymmetric beliefs about payoff-relevant parameters, agency conflicts, and the agent's implicit incentives to influence the principal's posterior beliefs through his unobservable actions interact to affect...
