Consider a financial market with nonnegative semimartingales which does not need to have a numeraire. We are interested in the absence of arbitrage in the sense that no self-financing portfolio gives rise to arbitrage opportunities, where we are allowed to add a savings account to the market. We will prove that in this sense the market is free of arbitrage if and only if there exists an equivalent local martingale deflator which is a multiplicative special semimartingale. In this case, the… Expand
Existence of equivalent local martingale deflators in semimartingale market models
This paper offers a systematic investigation on the existence of equivalent local martingale deflators, which are multiplicative special semimartingales, in financial markets given by positiveExpand
Exploiting arbitrage requires short selling
We show that in a financial market given by semimartingales an arbitrage opportunity, provided it exists, can only be exploited through short selling. This finding provides a theoretical basis forExpand

Diffusion-Based Models for Financial Markets Without Martingale Measures
We consider a general class of diffusion-based models and show that, even in the absence of an Equivalent Local Martingale Measure, the financial market may still be viable, in the sense that strongExpand
No Arbitrage and the Growth Optimal Portfolio
Abstract Recently, several papers have expressed an interest in applying the Growth Optimal Portfolio (GOP) for pricing derivatives. We show that the existence of a GOP is equivalent to the existenceExpand
The no-arbitrage property under a change of numéraire
For a price process that has an equivalent risk neutral measure, we investigate if the same property holds when the numeraire is changed. We give necessary and sufficient conditions under which theExpand
The numéraire portfolio in semimartingale financial models
TLDR
It is shown that the notion of a no-free-lunch-type notion is the minimal a-priori assumption required in order to proceed with utility optimization, something that the stronger NFLVR condition lacks. Expand
Finitely Additive Probabilities and the Fundamental Theorem of Asset Pricing
This work aims at a deeper understanding of the mathematical implications of the economically-sound condition of absence of arbitrages of the first kind in a financial market. In the spirit of theExpand
Weak and Strong No-Arbitrage Conditions for Continuous Financial Markets
We propose a unified analysis of a whole spectrum of no-arbitrage conditions for financial market models based on continuous semimartingales. In particular, we focus on no-arbitrage conditions weakerExpand
Martingales and stochastic integrals in the theory of continuous trading
This paper develops a general stochastic model of a frictionless security market with continuous trading. The vector price process is given by a semimartingale of a certain class, and the generalExpand
A Benchmark Approach to Quantitative Finance
The benchmark approach provides a general framework for financial market modeling, which extends beyond the standard risk-neutral pricing theory. It permits a unified treatment of portfolioExpand
On the Existence of Martingale Measures in Jump Diffusion Market Models
In the context of jump-diffusion market models we construct examples that satisfy the weaker no-arbitrage condition of NA1 (NUPBR), but not NFLVR. We show that in these examples the only candidateExpand
No‐Arbitrage in a Numéraire‐Independent Modeling Framework
The classic approach to modeling financial markets consists of four steps. First, one fixes a currency unit. Second, one describes in that unit the evolution of financial assets by a stochasticExpand
