Focusing on the model of demand-driven innovation and spatial competition over time in Jovanovic and Rob (1987), we study the effects of the robustness of estimators employed by firms to make inferences about their markets on the firms’ growth patterns. We show that if consumers’ signals in...

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...

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...

Dans le cadre du contexte francais actuel, les PME qui ne peuvent pas s'autofinancer et qui n'ont pas acces au marche financier (trop petit chiffre d'affaires) sont fortement dependantes des banques. Elles rencontrent des difficultes a se faire reconnaitre a leur juste valeur du faitd'une...

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...

We model a firm's choice between exporting and investing in a foreign country in the presence of possibly persistent demand uncertainty. We allow for demand shocks that, while increasing expected profit, impede learning. The firm learns gradually, in a Bayesian fashion, by observing past demand...

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...

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...

We quantify the impact of merger activity on productive efficiency. We develop and calibrate a dynamic industry-equilibrium model that features mergers, entry, and exit by heterogeneous firms. Mergers affect productivity directly through realized synergies, and indirectly through firms'...
