Underground labor, search frictions and macroeconomic fluctuations
No full textWe study the effects of underground activities on labour market dynamics in a RBC model with search frictions in the labor market, bargained wage and quadratic hiring costs. Underground activities, which allow agents to (partially) evade taxes, are modelled through a moonlighting production scheme where both regular and underground labor use the same capital equipment inside the firm. Calibrating the model on the U.S. economy, we show that a higher relative size of underground production implies lower average employment and a lower job finding rate, together with higher volatility of employment and lower volatilities of hours worked and wages of regular labor services. The theoretical explanation we provide is that a higher level of the underground activity increases the ratio of the flow contribution of non-working to the flow contribution of a worker to a labour match
Rational expectations and loss aversion: Potential output and welfare implications
No full textWe add some elements of prospect theory to an analytically tractable version of Lucas’s islands model and show that the inclusion of reference dependence, declining sensitivity and loss aversion into the agents’ utility function leads to four main results. First, the presence of behavioral elements negatively affects the natural level of output. Second, loss aversion reduces output variance. Third, the expected utility of a representative agent is generally lower than that obtained when loss aversion is absent. Fourth, the presence of loss aversion eliminates the paradoxical increase in expected utility that may be generated, in the standard model, by an increase in monetary policy uncertainty

Multi-input Multi-Output Identication for Control of Adaptive Optics Systems
No full textIn this paper, modern subspace identication methods are applied to a Multi-conjugate Adaptive optics Demonstrator, MAD, developed at ESO. The identied multi-input multi-output systems mapping voltages into slopes can be obtained on data taken in open/closed loop on beacon and in both SCAO and GLAO congurations. The advantages of the proposed approach is twofold: on the one hand the experiment to collect the data takes only few minutes during day time, it can be done on beacon, and all the computational eort is moved on-line. On the other hand, subspace identication provides the mathematical model necessary to design modern model-based controllers (e.g. linear quadratic control)
Revisiting the role of multiplicative uncertainty in a model without inflationary bias
Full text linkKobayashi (2003) aims to show that, in a model without inflationary bias, an increase in the degree of multiplicative uncertainty on the transmission mechanism of monetary policy improves social welfare when central bank’s preferences are highly uncertain. We demonstrate that this result applies only to the case in which society is strictly conservative, i.e., when the weight attached to output in the social welfare function is lower than one
Power or loss aversion? Reinterpreting the bargaining weights in search and matching models
No full textWe show that in a modified Mortensen–Pissarides model the bargaining weights depend on the players’ loss-aversion parameters. These weights can hence be calibrated without resorting to an assessment of players’ bargaining powers, which have proved difficult to empirically establish
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
