What is at stake in the climate negotiations is the provision of a global public good, indeed a "clean" atmosphere.The Kyoto Protocol is only a very minor step toward this objective. Looking further ahead in time, beyond the 2008-2012 period, Annex I Parties' commitments will not be sufficient...

This paper examines the consequences of various attitudes towards climate damages through a family of stochastic optimal control models (RESPONSE): cost-efficiency for a given temperature ceiling; cost-benefit analysis with a "pure preference for current climate regime" and full cost-benefit...

We study the influence of taking liquidity costs and market impact into account when hedging a contingent claim, first in the discrete time setting, then in continuous time. In the latter case and in a complete market, we derive a fully non-linear pricing partial differential equation, and...

We derive explicit recursive formulas for Target Close (TC) and Implementation Shortfall (IS) in the Almgren-Chriss framework. We explain how to compute the optimal starting and stopping times for IS and TC, respectively, given a minimum trading size. We also show how to add a minimum...

We introduce a new model in order to describe the fluctuation of tick-by-tick financial time series. Our model, based on marked point process, allows us to incorporate in a unique process the duration of the transaction and the corresponding volume of orders. The model is motivated by the fact...

This paper investigates the relation between liquidity and asset prices. It shows that, when banks balance sheets are marked to market and banks are targeting a financial leverage level - a situation similar to current environment - formation of Leverage Bubble phenomenon and suggests a new...

We build a continous-time general equilibrium model of a two-country, pure-exchange economy featuring taxes on the repatriation of dividends. We find approximate closed-form expressions for asset prices, returns joint dynamics and equity portfolios, thus giving a full description of equilibrium...

This paper studies the effects of multiple investment horizons and investors' bounded rationality on the price dynamics. We consider a pure exchange economy with one risky asset, populated with agents maximizing CRRA-type expected utility of wealth over discrete investment periods. An investor's...

The aim of the paper is to analyze the impact of heterogeneous beliefs in an otherwise standard competitive complete markets discrete time economy. The construction of a consensus belief, as well as a consensus consumer are shown to be valid modulo a predictable aggregation bias, which takes the...

Impact of monetary policy on asset prices : lessons from a MIU model applied to the Fed Abstract -A tractable consumption-based and money-based asset pricing model is built to relate in closed form the risk premium, the risk free rate and the volatility of asset price to parameters of monetary...
