Walrasian Dynamics in Multi-unit Markets

In a multi-unit market, a seller brings multiple units of a good and tries to sell them to a set of buyers that have monetary endowments. While a Walrasian equilibrium does not always exist in this model, natural relaxations of the concept that retain its ...

Welfare effects of technology-based climate policies in liberalized electricity markets: seeing beyond total system cost

Philippe Thalmann, Frank Vöhringer, Sophie Maire

This paper is a contribution to assessing the Swiss energy transition, with an emphasis on the consequences of decommissioning the nuclear power plants for the electricity market and the whole economy. We expect that increased renewable generation and dema ...

Change of beam distribution due to decoherence in the presence of transverse feedback

Xavier Buffat, Sondre Vik Furuseth

The effect of Landau damping is often calculated based on a Gaussian beam distribution in all degrees of freedom. The stability of the beam is however strongly dependent on the details of the distribution. The present study focuses on the change of bunch d ...

From COP21 pledges to a fair 2°C pathway

Marc Vielle, Frédéric Louis François Babonneau, Alain Haurie

At COP21, about 160 countries proposed the so-called INDCs that define GHG abatement objectives by 2030. While encouraging, these commitments are not ambitious enough to achieve the 2°C threshold by 2100, and further negotiations are needed for sharing the ...

Meta-Modeling to Assess the Possible Future of Paris Agreement

Marc Vielle, Frédéric Louis François Babonneau, Alain Haurie, Alain Bernard

In the meta-modeling approach, one builds a numerically tractable dynamic optimization or game model in which the parameters are identified through statistical emulation of a detailed large scale numerical simulation model. In this paper, we show how this ...

Combining Structural and Timing Errors in Overclocked Inexact Speculative Adders

Christian Enz, Vincent Frédéric Camus, Mattia Cacciotti, Yu Jiang, Xun Jiao

Worst-case design is used in IoT devices and high performance data centers to ensure reliability, leading to a power efficiency loss. Recently, approximate computing has been proposed to trade off accuracy for efficiency. In this paper, we use Inexact Spec ...

Managing morning commute with parking space constraints in the case of a bi-modal many-to-one network

Wei Liu, Fangni Zhang

Recently, some studies examined how downtown parking space limitation re-shapes the morning commute in the case of a single origin-destination network. This paper further formulates and analyses the commuting equilibrium problem of both mode and departure ...

Assessment of balanced burden-sharing in the 2050 EU climate/energy roadmap: a metamodeling approach

Marc Vielle, Frédéric Louis François Babonneau, Alain Haurie

In this paper we propose a non-cooperative meta-game approach to designing and assessing climate agreements among 28 European countries that will be compatible with the EU 2050 climate target. Our proposed game model is identified through statistical emula ...

Efficiency of a highway use reservation system for morning commute

Wei Liu

This paper examines the design and efficiency of a highway use reservation system where commuters need reservations to access a highway facility at specific times. We show that, by accommodating reservation requests to the level that the highway capacity a ...

Impact of uncertain CCS deployment on EU climate negotiations

Marc Vielle, Frédéric Louis François Babonneau, Alain Haurie

In this paper we propose a stochastic non-cooperative meta-game approach to assess the role of uncertain CCS deployment on climate agreements among 28 European countries. The game model is identified through statistical emulation of a large set of numerica ...
