Evaluating CO2 breakthrough in a shaly a caprock material: a multi-scale experimental approach

Lyesse Laloui, Eleni Stavropoulou

The potential of underground CO2 storage relies on the sealing efficiency of an overlaying caprock that acts as a geological barrier. Shales are considered as potential caprock formations thanks to their favourable hydro-mechanical properties. In this work ...

Optimization and equilibrium problems with discrete choice models

Stefano Bortolomiol

Many transportation markets are characterized by oligopolistic competition. In these markets customers, suppliers and regulators make decisions that are influenced by the preferences and the decisions of all other agents. In particular, capturing and under ...

A demand-based optimization approach to find market equilibria in oligopolies

Stefano Bortolomiol

Oligopolistic competition occurs often in transportation as well as in other markets due to reasons such as barriers to entry, limited capacity of the infrastructure and external regulations. In transport oligopolies, suppliers are profit maximizers and ta ...

The Advent of the Sharing Culture and its Effect on Product Pricing

Thomas Alois Weber, Maryam Razeghian Jahromi

Empirical observations suggest that consumers' propensity towards sharing varies with culture and the individuals' socio-demographic characteristics. In an economy with overlapping generations of heterogeneous consumers, we study optimal dynamic selling by ...

Equilibrium commodity prices with irreversible investment and non-linear technologies

Pierre Collin-Dufresne

We model oil price dynamics in a general equilibrium production economy with two goods: a consumption good and oil. Production of the consumption good requires drawing from oil reserves at a fixed rate. Investment necessary to replenish oil reserves is cos ...

Microwave Imaging of Brain Stroke : Contributions to Modeling and Inverse Problem Resolution

Mina Bjelogrlic

Brain stroke is an age-related illness which has become a major issue in our ageing societies. Early diagnosis and treatment are of high importance for the full recovery of the patient, as reminded in Anglo-Saxon countries by the abbreviation FAST (Face, A ...

Smart Products for Sharing

Thomas Alois Weber

Sharing markets create mutual insurance for consumers who are unsure about their future needs for goods, thus rendering products more valuable both before and after the purchase. By embedding intelligence in their products, enabling them to sense, monitor, ...

Controlling and Pricing Shareability

Thomas Alois Weber

In the presence of a peer-to-peer economy, the option of sharing an item is valuable for consumers. By retaining control over the shareability of its products a monopolist can set a sharing tariff in conjunction with the purchase price of the product, in o ...

Parameter Learning in General Equilibrium: The Asset Pricing Implications

Pierre Collin-Dufresne

Parameter learning strongly amplifies the impact of macroeconomic shocks on marginal utility when the representative agent has a preference for early resolution of uncertainty. This occurs as rational belief updating generates subjective long-run consumpti ...

Urbaniser les Alpes suisses : stratégies de densification des villes en altitude

Fiona Pia

Regional planning, especially in the Alps, is high on the current news agenda in Switzer- land, more so than ever before. The skiing boom has driven massive urbanisation in mountain areas, primarily in locations at altitudes of 1400m or higher. For several ...

Collaborative Housing and the Intermediation of Moral Hazard

Thomas Alois Weber

This paper considers intermediation in a differentiated short-term housing market where heterogeneous agents may stay at a hotel or at one of several private hosts' properties, below or above hotel quality. The collaborative-housing market fails when agent ...

Financial Frictions within the Macroeconomy : Policy Analysis from an Empirical and Theoretical Perspective

Victoria Nuguer

Financial factors are central to the recent economic crisis. Most macroeconomic models treat banks and financial intermediation as a veil. These models are unable to account for the recent financial crisis and they cannot be used for policy evaluation. Fin ...

Estimation of bid functions for location choice and price modeling with a latent variable approach

Michel Bierlaire, Ricardo Daniel Hurtubia González

A new approach for the estimation of bid-rent functions for residential location choice is proposed. The method is based on the bid-auction approach and considers that the expected maximum bid of the auction is a latent variable that can be related to obse ...

Financial Markets Equilibrium with Heterogeneous Agents

Semyon Malamud

This paper presents an equilibrium model in a pure exchange economy when investors have three possible sources of heterogeneity. Investors may differ in their beliefs, in their level of risk aversion, and in their time preference rate. The authors study th ...

Simplified models for LHC new physics searches

Roberto Franceschini

This document proposes a collection of simplified models relevant to the design of new-physics searches at the Large Hadron Collider (LHC) and the characterization of their results. Both ATLAS and CMS have already presented some results in terms of simplif ...

Risky Mortgages in a DSGE Model

Luisa Lambertini, Chiara Forlati

This paper develops a DSGE model with housing, risky mortgages, and endogenous default. Housing investment is subject to idiosyncratic risk, and some mortgages are defaulted in equilibrium. An unanticipated increase in the standard deviation of housing inv ...

Price impact and portfolio impact

Semyon Malamud

We study survival, price impact, and portfolio impact in heterogeneous economies. We show that, under the equilibrium risk-neutral measure, long-run price impact is in fact equivalent to survival, whereas long-run portfolio impact is equivalent to survival ...

Relative Extinction of Heterogeneous Agents

Semyon Malamud

In all the existing literature on survival in heterogeneous economies, the rate at which an agent vanishes in the long run relative to another agent can be characterized by the diﬀerence of the so-called survival indices, where each survival index only dep ...

Universal Bounds for Asset Prices in Heterogeneous Economies

Semyon Malamud

We establish universal bounds for asset prices in heterogeneous complete market economies with scale invariant preferences. Namely, for each agent in the economy we consider an artiﬁcial homogeneous economy populated solely by this agent, and calculate the ...

Asset trading volume in infinite-horizon economies with dynamically complete markets and heterogeneous agents: Comment

In a recent paper, Judd et al. [2003. Journal of Finance 58, 2203-2217] study asset trading in a version of the standard Lucas infinite horizon economy with heterogeneous agents. They report the surprising finding that (for generic economies in their class ...
