This paper provides a fully micro-founded New Keynesian framework to study the interaction between oil price volatility, pricing behavior of firms and monetary policy. We show that when oil has low substitutability, firms find it optimal to charge higher relative prices as a premium in...

Equilibrium models have been proposed in literature with the aim of describing the evolution of the price of emission permits. This paper derives first a reducedform model from an equilibrium model and thereby explains how existing reducedform models are related to equilibrium models. Second, by...

Speculative industries exploit novel technologies subject to two risks. First, there is uncertainty about the fundamental value of the innovation: is it strong or fragile? Second, it is difficult to monitor managers, which creates moral hazard. Because of moral hazard, managers earn agency rents...

We show, in an exchange economy with default, liquidity constraints and no aggregate uncertainty, that state prices in a complete markets general equilibrium are a function of the supply of liquidity by the Central Bank. Our model is derived along the lines of Dubey and Geanakoplos (1992). Two...

This paper surveys asset allocation methods that extend the traditional approach. An important feature of the traditional approach is that measures the risk and return tradeoff in terms of mean and variance of final wealth. However, there are also other important features that are not always...

This paper introduces a new class of parameter estimators for dynamic models, called Simulated Nonparametric Estimators (SNE). The SNE minimizes appropriate distances between nonparametric joint (or conditional) densities estimated from sample data and nonparametric joint (or conditional)...

After the seminal paper of Jarrow and Rudd (1982), several authors have proposed to use different statistical series expansion to price options when the risk-neutral density is asymmetric and leptokurtic. Amongst them, one can distinguish the Gram-Charlier Type A series expansion (Corrado and...

The paper draws lessons from the experience of the past year for the conduct of central banks in the pursuit of macroeconomic and financial stability. Macroeconomic stability is defined as either price stability or as price stability and sustainable output or employment growth. Financial...

This paper provides evidence that managers adjust firm advertising, in part, to attract investor attention and influence short-term stock returns. First, I show that increased advertising spending is associated with a contemporaneous rise in retail buying and abnormal stock returns, and is...

This paper introduces a new parameter estimator of dynamic models in which the state is a multidimensional, continuous-time, partially observed Markov process. The estimator minimizes appropriate distances between nonparametric joint (and/or conditional) densities of sample data and...
