Pre-trade transparency and trade size
No full textWe analyse how Pre-Trade Transparency (PTT) affects the behaviour of
different stock traders. To do so, we exploit a natural experiment, that is
the PTT change in the equity segment of Italian Stock Exchange (ISE)
which occurred in July 2007, with the aim of reducing information
asymmetries between individuals and intermediaries/institutional investors.
We specify a dynamic empirical model for trade size and estimate it
on a large panel of tick-by-tick data. Results suggest that increased
transparency affects the dynamic trade pattern emerging from interacting
strategic decisions of different traders. In addition, the contribution of the
order flow disclosure both in reducing the adverse selection component of
the bid–ask spread, and in weakening the sensitiveness to risk of the trade
size also emerges. Overall, PTT enhancement should reduce the informative
disequilibrium among market participants and improve the quality of
the market
Rationality or 'gut feelings': what drives insurance demand?
No full textThis paper investigates whether an individual’s emotional profile affects their insurance decision making. We explore how the emotional reaction in conditions of ambiguity and the fear of the unknown affect insurance choices. We conducted psychophysiological experiments on a sample of 645 individuals and find evidence that these emotional variables offer contributions by increasing the predictive power of models for insurance demand, alongside traditional socioeconomic variables and psychographic traits. A selective role of emotional influence has been proven to exist when comparing different insurance policies, such as life, health, casualty and indemnity insurance
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
