Ju l 2 01 2 DO ARBITRAGE - FREE PRICES COME FROM UTILITY MAXIMIZATION ? BY PIETRO SIORPAES

  • PIETRO SIORPAES
چکیده

In this paper we ask whether arbitrage-free prices are obtained by utility maximization. This is found to be true for any given investor, provided that one considers the marginal utility-based prices relative to all initial endowments with finite utility.

Machine Learning Vasicek Model Calibration with Gaussian Processes

In this paper we calibrate the Vasicek interest rate model under the risk neutral measure by learning the model parameters using Gaussian processes for machine learning regression. The calibration is done by maximizing the likelihood of zero coupon bond log prices, using mean and covariance functions computed analytically, as well as likelihood derivatives with respect to the parameters. The ma...

Edgeworth and Walras equilibria of an arbitrage-free exchange economy

In this paper, we first give a direct proof of the existence of Edgeworth equilibria for exchange economies with (possibly) unbounded below consumption sets. The key assumption is that the individually rational utility set is compact. It is worth noticing that the statement of this result and its proof do not depend on the dimension or the particular structure of the commodity space. In a secon...

A New View on the Fundamental Theorem of Asset Pricing for Large Financial Markets

In the context of large financial markets we formulate the notion of no asymptotic free lunch with vanishing risk (NAFLVR), under which we can prove a version of the fundamental theorem of asset pricing (FTAP) in markets with an (uncountably) infinite number of assets, as it is for instance the case in bond markets. We work in the general setting of admissible portfolio wealth processes as laid...

On the Pricing of Contingent Claims under Constraints

We discuss the problem of pricing contingent claims, such as European call-options, based on the fundamental principle of “absence of arbitrage” and in the presence of constraints on portfolio choice, e.g. incomplete markets and markets with short-selling constraints. Under such constraints, we show that there exists an arbitrage-free interval which contains the celebrated Black-Scholes price (...

Resilient price impact of trading and the cost of illiquidity

We construct a model for liquidity risk and price impacts in a limit order book setting, and derive a wealth equation and a characterization of illiquidity costs for liquidity providers. The model has desirable stylized facts justified by empirical studies and contains all three components identified by Kyle (1985). We give conditions under which the model is arbitrage free. By considering the ...
