A behavioural finance approach to commodity supply scares
Full text linkThis study aims to generate a more robust understanding of public attitudes regarding non-renewable natural resource markets. Employing a comparative-historical case study method, it analyzes three waves of widespread fear that swept the United States over the course of the twentieth century regarding an imminent, irreversible shortage of oil. Each of these periods of fear over oil supply availability coincided with a significant rise in the price of crude oil, only to be followed by a sudden collapse as new production came onstream in response to higher prices. The study utilizes process tracing and pattern matching techniques to examine the linkages between fundamental supply-demand conditions in the crude oil market, oil price movements, and expert predictions of and other public expressions of belief that oil in the United States would become scarcer and more expensive in the future.This dissertation’s core arguments contribute to existing theoretical debates in three ways. First, by providing a comparative historical portrait of cyclical patterns in public and expert beliefs regarding non-renewable resource availability and long-term price behavior, the study puts contemporary debates over the future of oil supply in historical perspective. It allows the rampant claims of, and widespread belief in, a global shortage of oil that have gained popularity over the last decade—most notably, in the so-called “peak oil” movement—to be situated within a broader chronological context. It also extends and deepens earlier historical work analyzing oil shortage scares in the United States, both in terms of their underlying dynamics and their effect on federal government policy relative to the oil industry.Second, the study establishes the link between fundamental supply-demand conditions in the oil market, generally reflected in oil prices, and the degree of media attention given to, and apparent public belief in, an imminent, irreversible shortage of oil in the United States over the course of the twentieth century. In so doing, it demonstrates the applicability of Shiller’s (2000, 2005) conceptualization of new era economic theory formation and popularization to observed phenomena in the oil market, but with a crucial difference. Rather than new era economic thinking taking the form of unbounded optimism about the future, in the case of the oil market new era thinking has tended to be manifested as the pessimistic belief that an impending, irreversible shortage of oil would lead to a long-term, even perpetual, rise in oil prices.The study suggests two modifications to the concept that enhance its greater explanatory leverage with regard to exhaustible resource markets: one, that often the new era predictions most widely cited during shortage scares were actually made prior to the boom in prices, to little fanfare, but subsequently deemed prophetic by new era proponents; and two, that the new era narratives often contained normative elements. Moral judgments—in particular, condemnation of the oil economy’s degradation of the natural environment—have often intertwined with predictions that the oil supply was more limited than widely believed and that prices were destined to continue rising.Third, the study demonstrates that the concept of narratives of decline, as described by Bennett (2001) and Lieber (2008), constitutes a powerful theoretical lens through which to understand trends in popular opinion with regard to non-renewable resource availability, and to asset prices more generally—a link that has heretofore gone unrecognized. It finds that a positive feedback loop tended to exist between popular fears of a new era of oil shortages, marked by a long-term rise in prices, and related narratives of the environmental and relative political-economic decline of the United States

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
