Weak and strong no-arbitrage conditions for continuous financial markets

نویسنده

  • Claudio Fontana
چکیده

We propose a uni ed analysis of a whole spectrum of no-arbitrage conditions for nancial market models based on continuous semimartingales. In particular, we focus on no-arbitrage conditions weaker than the classical notions of No Arbitrage and No Free Lunch with Vanishing Risk. We provide a complete characterisation of all no-arbitrage conditions, linking their validity to the existence and to the properties of (weak) martingale de ators and to the characteristics of the discounted asset price process.

Interest rates parity and no arbitrage as equivalent equilibrium conditions in the international financial assets and goods markets

In this paper, we consider a two-period consumption model with many financial assets. In the spirit of Hart [5], consumers purchase financial assets in period 0 and consume in period 1. We differ from Hart by considering that each agent is a country. We provide conditions for the existence of an equilibrium in both international financial assets and goods markets. First, we introduce a weaker n...

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...

Necessary and Sufficient Conditions for Weak No-Arbitrage in Securities Markets with Frictions

In this paper we consider a financial market model with frictions which include transaction costs, bid-ask spread and taxes. By using optimization, linear and nonlinear programming and convex programming techniques, several necessary and sufficient conditions are derived for the weak no-arbitrage. Some results on state prices are also provided. The results of this paper can provide at least som...

Arbitrage in Housing Markets

Urban economists understand housing prices with a spatial equilibrium approach that assumes people must be indifferent across locations. Since the spatial no arbitrage condition is inherently imprecise, other economists have turned to different no arbitrage conditions, such as the prediction that individuals must be indifferent between owning and renting. This paper argues the predictions from ...
