Sincere Voting with Cardinal Preferences: Approval Voting
We discuss sincere voting when voters have cardinal preferences over alter- natives. We interpret sincerity as opposed to strategic voting, and thus define sincerity as the optimal behaviour when conditions to vote strategically vanish. When voting mechanisms allow for only one message type we show that this op- timal behaviour coincides with an intuitive and common definition of sincerity. For voting mechanisms allowing for multiple message types, such as approval vot- ing (AV), there exists no conclusive definition of sincerity in the literature. We show that for AV, voters' optimal strategy tends to one of the existent definitions of sincerity, consisting in voting for those alternatives that yield more than the average of cardinal utilities.sincere and strategic voting, approval voting
Optimal education and pensions in an endogenous growth model
It is well known that, in OLG economies with life-cycle saving and exogenous growth, competitive equilibria will in general fail to achieve optimality and may even be dynamically inefficient. This is a consequence of individuals accumulating amounts of physical capital that differ from the level which would maximize welfare along a balanced growth path (the Golden Rule). With human capital, a second potential source of departure from optimality arises, to wit: individuals may not choose the correct amount of education investment. However, the Golden Rule concept, widely used in exogenous growth frameworks, has not found its way into endogenous growth models. In this paper, we propose to recover the Golden Rule of physical and also human capital accumulation. The optimal policy to decentralize the Golden Rule balanced growth path when there are no constraints for individuals to finance their education investments is also characterized. It is shown that it involves positive pensions and negative education subsidies (i.e., taxes)endogenous growth, human capital, intergenerational transfers, education policy
On welfare criteria and optimality in an endogenous growth model
In this paper we explore the consequences for optimality of a social planner adopting two different welfare criteria. The framework of analysis is an OLG model with physical and human capital. We first show that, when the SWF is a discounted sum of individual utilities defined over consumption per unit of natural labour, the precise cardinalization of the individual utility function becomes crucial for the characterization of the social optimum. Also, decentralizing the social optimum requires an education subsidy. In contrast, when the SWF is a discounted sum of individual utilities defined over consumption per unit of efficient labour, the precise cardinalization of preferences becomes irrelevant. More strikingly, along the optimal growth path, education should be taxed.endogenous growth, human capital, intergenerational transfers, education policy
Sincerity in Simple and Complex Voting Mechanisms
We discuss sincere voting when voters have cardinal preferences over alternatives. We interpret sincerity as opposed to strategic voting, and thus define sincerity as the optimal behavior when conditions to vote strategically diminish. When voting mechanisms allow for only one message type (simple voting mechanisms) we show that eliminating some conditions for strategic voting, individuals' optimal behavior coincides with an intuitive and common definition of sincerity. In order to obtain a precise definition of sincerity in voting mechanisms allowing for multiple message types (complex voting mechanisms) further restrictions on strategic voting are required. We illustrate our methodological approach using approval voting (AV) as a prime example of complex voting mechanisms for which no conclusive definition of sincerity exists in the literature.sincere and strategic voting, cardinal utility, approval voting
First-principles study of lithium-doped carbon clathrates under pressure
We present a theoretical study on the behavior under pressure of the two
hypothetical C and LiC type-I carbon clathrates in order to
bring new informations concerning their synthesis. Using \textit{ab initio}
calculations, we have explored the energetic and structural properties under
pressure of these two carbon based cage-like materials. These low-density
meta-stable phases show large negative pressure transitions compared to diamond
which represent a serious obstacle for their synthesis. However, we evidence
that a minimum energy barrier can be reached close to 40 GPa, suggesting that
the synthesis of the Li-clathrate under extreme conditions of pressure and
temperature may be possible. Electronic band structure with related density of
states behavior under pressure as well as the dependence of the active Raman
modes with pressure are also examined
Non-monotonic entanglement of physical EM field states in non-inertial frames
We develop a general technique to analyse the quantum effects of acceleration
on realistic spatially-localised electromagnetic field states entangled in the
polarization degree of freedom. We show that for this setting, quantum
entanglement may build up as the acceleration increases, providing a clear
signature of the quantum effects of relativistic acceleration.Comment: 5 pages, 3 figure
Energy demand prediction for the implementation of an energy tariff emulator to trigger demand response in buildings
Buildings are key actors of the electrical gird. As such they have an important role to play in grid
stabilization, especially in a context where renewable energies are mandated to become an increasingly
important part of the energy mix. Demand response provides a mechanism to reduce or displace electrical
demand to better match electrical production. Buildings can be a pool of flexibility for the grid to operate
more efficiently. One of the ways to obtain flexibility from building managers and building users is the
introduction of variable energy prices which evolve depending on the expected load and energy generation.
In the proposed scenario, the wholesale energy price of electricity, a load prediction, and the elasticity of
consumers are used by an energy tariff emulator to predict prices to trigger end user flexibility. In this paper,
a cluster analysis to classify users is performed and an aggregated energy prediction is realised using Random
Forest machine learning algorithm.This paper is part of a project that has received funding

INNDAGA: an environmental data acquisition innovation platform
INNDAGA is a multipurpose platform for conducting oceanographic
surveys in coastal areas developed on an 8.5 m long inflatable boat. This concept
allows the vessel to operate safely and with great manoeuvring flexibility in areas
where larger research vessels cannot access (rocky areas, port ...) at low operational
cost. Is fully integrated in an information management system to providing efficiency
and effectiveness of strategic decision making.Peer Reviewe
Electromotive force and internal resistance of an electron pump
We present a scattering theory of the electromotive force and internal
resistance of an electron pump. The characterization of the device performance
in terms of only two parameters requires the assumption of incoherent multiple
scattering within the circuit and complete thermalization among electrons
moving in a given direction. The electromotive force is shown to be of the
order of the driving frequency in natural units. In an open setup, the
electromotive force adds to the voltage difference between reservoirs to drive
the current, both facing a contact resistance which is absent in the case of a
closed circuit of uniform width
