Efeitos de pares em active learning: explorando alocação exógena de grupos
2018This paper investigates peer effects in higher education in an environment of active learning that gives great importance for students' interaction through group work. Our empirical strategy uses exogenous variation in ... -
On the use of multi-stakeholder governance in institutional crises
2018Institutional crises might affect the credibility of companies but also a specific sector. This study illustrates that organizations purposively engage in multiple partnerships, across different institutional levels, and ... -
Demand for trucks in brazil: an econometric approach
2018The demand for trucks in Brazil has historically been an unusual choice for econometric analysis, resulting in a scarcity of studies on this subject, inconsistent with the economic relevance of road freight transport and ... -
Symbolic megaprojects: historical evidence of a forgotten dimension
2018By combining an historical analysis of three megaprojects and an organizational theory approach based on the notion of symbolism-intensive organizations, this research attempts to shed light on how symbols are constructed, ... -
Automatic indexing and ontologies: the consistency of the research chronology and authoring in the scope of Information Science
2018An alternative to minimize the semantic gap in automatic indexing systems is to make use of knowledge organization systems, like ontologies. Given that these two operational concepts are subjects of study in Information ... -
Optimal control of infinite dimensional bilinear systems: application to the heat and wave equations
2018In this paper we consider second order optimality conditions for a bilinear optimal control problem governed by a strongly continuous semigroup operator, the control entering linearly in the cost function. We derive first ... -
Distributional counterfactual analysis with (common) deterministic trend units
2018-01The goal of this paper is to extend the counterfactual methodologies in particular Carvalho et al. (2016), by considering the estimation of quantile counterfactuals in the presence of trend units. We derive an asymptotically ... -
Individuals neglect the informational role of prices: evidence from the stock market
2018-02We find that a stock price fall in itself induces individual investors to buy the stock. That is, individuals neglect the negative information that may be attached to a stock price fall. Our identification strategy uses ... -

Money and credit remix
2018-02-19Gu, Mattesini, and Wright (2016) show that credit is irrelevant in a monetary economy with permanent buyer and seller types. In particular, the size of debt limits do not matter for the determination of real allocations. ... -
On the robustness of the principal volatility components
2018-03In this paper, we analyse the recent principal volatility components analysis procedure. The procedure overcomes several diculties in modelling and forecasting the conditional covariance matrix in large dimensions arising ... -
Smoothing quantile regressions
2018-04-08We propose to smooth the entire objective function rather than only the check function in a linear quantile regression context. We derive a uniform Bahadur-Kiefer representation for the resulting convolution-type kernel ... -
Nonparametric assessment of hedge fund performance
2018-04-23We propose a new class of performance measures for Hedge Fund (HF) returns based on a family of empirically identifiable stochastic discount factors (SDFs). These SDF-based measures incorporate no-arbitrage pricing ... -
Is the new keynesian is curve forward looking?
2018-04-27This paper analyzes the solutions of the canonical and hybrid New Keynesian IS curve difference equation. It shows that the usual forward solution is ruled out because it is at odds with the underlying economic theory. ... -
Social cryptocurrencies: social finance organizations at the new era of digital community currencies
2018-07-07We proposed an investigation on the emergent phenomenon of cryptocurrencies by studying those with explicit social or environmental goals, that we called social cryptocurrencies. To perform this study, we adopt a socialmaterial ...
