Real options signaling games with applications to corporate finance,
No full textWe study games in which the decision to exercise an option is a signal of private information to outsiders, whose beliefs affect the utility of the decision-maker. Signaling incentives distort the timing of exercise, and the direction of distortion depends on whether the decision-maker's utility increases or decreases in outsiders' belief about the payoff from exercise. In the former case, signaling incentives erode the value of the option to wait and speed up option exercise, while in the latter case option exercise is delayed. We demonstrate the model's implications through four corporate finance settings: investment under managerial myopia, venture capital grandstanding, investment under cash flow diversion, and product market competition. (JEL G31, D82) The real options approach to investment and other corporate finance decisions has become an increasingly important area of research in financial economics. The main underlying concept is that an investment opportunity is valuable not only because of associated cash flows but also because the decision to invest can be postponed. As a result, when making the investment decision, one must take into account both the direct costs of investment and the indirect costs of foregoing the option to invest in the future. The applications of the real options framework have become quite broad. 1 We thank the anonymous referee, Anat Admati, Felipe Aguerrevere, Geert Bekaert, Nina Boyarchenko, Cecilia Bustamante, Nadya Malenko, Ilya Strebulaev, Pietro Veronesi (the editor), Neng Wang, Jeffrey Zwiebel, seminar participants at Stanford University, and participants at the 2010 Western Finance Association Annual Meeting in Victoria, BC; the 2010 UBC Winter Finance Conference; and the 9 th Trans-Atlantic Doctoral Conference at LBS for their helpful comments.

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
OPTION EXERCISE GAMES: THE INTERSECTION OF REAL OPTIONS AND GAME THEORY
No full textWhile the real options approach has proven useful in providing an analytical framework for analyzing the timing of investment decisions, a notable failure of the approach has been an almost complete lack of strategic considerations. In standard real options models, invest-ment (and exercise) strategies are for-mulated in isolation, without considering the potential impact of other firms' exercise strategies. This paper illustrates how the intersection of real options and game theory provides powerful new insights into the behavior of economic agents under uncertainty. 2000 Morgan Stanley.
An Equilibrium Analysis of Real Estate
Get PDFThis paper provides a unified equilibrium approach to valuing a wide variety of commercial real estate lease contracts. Using a game-theoretic variant of real options analysis, the underlying real estate asset market is modeled as a continuous-time Nash equilibrium in which developers make construction decisions under demand uncertainty. Then, using the economic notion that leasing simply represents the purchase of the use of the asset over a specified time frame, I use a contingent-claims approach to value many of the most common real estate leasing arrangements. In particular, the model provides closed-form solutions for the equilibrium valuation of leases with options to purchase, pre-leasing, gross and net leases, leases with cancellation options, ground leases, escalation clauses, lease concessions and sale-leasebacks.
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
