This paper analyzes a principal-agent-model with a principal, a manager, and a team of workers to investigate the incentive provision and optimal team size in a setting with uncertain productivity and team synergy effects which is typical for innovation environments. Workers are responsible for...

Prior accounting and finance literatures document a positive relation between R&D investment and future operating performance, implicitly assuming that the benefits from R&D are independent of other resources. However, the economics and strategy literature provides a framework that other...

This paper studies the decision of firms to expense or capitalize R&D expenditures. The firm has an incentive to mismatch the benefits and costs of R&D, expensing a larger portion of R&D when the benefits occur in the long-run and capitalizing a larger portion when the benefits occur in the...

The immediate expensing of R&D expenditures conceals managers' knowledge about the R&D projects. I examine whether higher R&D-intensive firms voluntarily guide more to decrease this information asymmetry. R&D state tax credits serve as instrumental variable for R&D investments. While total...

Researchers have used patent counts, citation weighted patent counts, as well as research and development spending to measure innovation with, at times, conflicting results. We benchmark the validity of these innovation proxies using a novel data set of appraised tangible and intangible assets....

These are the presentation slides for the paper "Innovative Efficiency and Stock Returns". The abstract of the paper is the following: We find that innovative efficiency (IE), patents or citations scaled by research and development expenditures, is a strong positive predictor of future returns...

Disclosure of information triggers immediate price movements, but it mitigates price movements at a later date, when the information would otherwise have become public. Consequently, disclosure shifts risk from later cohorts of investors to earlier cohorts. Hence, disclosure policy can be...

Standard equity valuation approaches (i.e., DDM, RIM, and DCF model) are derived under the assumption of ideal conditions, such as infinite payoffs and clean surplus accounting. Because these conditions are hardly ever met, we extend the standard approaches, based on the fundamental principle of...

This paper investigates the extent to which voluntary disclosure quality (VDQ) of firms is reflected in equity prices. As a novel contribution, we explore the idea that the speed with which equity prices reflect any benefits or costs of VDQ varies across firms. We find that in environments where...

The purpose of this paper is to examine determinants of financial information disclosure by Tunisian companies. The methodology is based on qualitative approach, using the cognitive mapping technique. To take into account the specificities of the Tunisian economic, we felt that it is essential...
