Abstract: We investigate the term structure of zero coupon bonds when interest rates are driven by a general marked point process as well as by a Wiener process. Developing a theory that allows for measure–valued trading portfolios, we study existence and uniqueness of a martingale measure. We also study completeness and its relation to the uniqueness of a martingale measure. For the case of a finite jump spectrum we give a fairly general completeness result and for a Wiener–Poisson model we prove the existence of a time–independent set of basic bonds. We also give sufficient conditions for the existence of an affine term structure.

TL;DR: It is shown that a market is approximately complete iff an equivalent martingale measure is unique and two constructions of stochastic integrals with respect to processes taking values in a space of continuous functions are suggested.
Abstract: To the memory of our friend and colleague Oliviero Lessi. Abstract. The main purpose of the paper is to provide a mathematical back- ground for the theory of bond markets similar to that available for stock markets. We suggest two constructions of stochastic integrals with respect to processes taking values in a space of continuous functions. Such integrals are used to define the evolution of the value of a portfolio of bonds corresponding to a trad- ing strategy which is a measure-valued predictable process. The existence of an equivalent martingale measure is discussed and HJM-type conditions are derived for a jump-diffusion model. The question of market completeness is considered as a problem of the range of a certain integral operator. We introduce a concept of approximate market completeness and show that a market is approximately complete iff an equivalent martingale measure is unique.

Abstract: This paper describes the institutions and social norms that have accommodated corrup- tion in the Russian Federation in the post-transition years. We show how corruption is sustained by ill-defined boundaries between political and private business activity, and how the role of the state facilitates rather than hinders corruption. The paper draws upon a longer w

TL;DR: This paper gives a new proof which uses techniques from stochastic calculus rather than functional analysis, and which removes any boundedness assumption.
Abstract: Let $${\cal Q}$$ be the set of equivalent martingale measures for a given process $$S$$, and let $$X$$ be a process which is a local supermartingale with respect to any measure in $${\cal Q}$$. The optional decomposition theorem for $$X$$ states that there exists a predictable integrand $$\varphi$$ such that the difference $$X-\varphi\cdot S$$ is a decreasing process. In this paper we give a new proof which uses techniques from stochastic calculus rather than functional analysis, and which removes any boundedness assumption.

TL;DR: One of out discoveries is that a cycle detection strategy of Tarjan greatly improves computational performance of a classical shortest path algorithm, making it competitive with the fastest known algorithms on a wide range of problems.
Abstract: We study the problem of finding a negative length cycle in a network. An algorithm for the negative cycle problem combines a shortest path algorithm and a cycle detection strategy. We survey cycle detection strategies, study various combinations of shortest path algorithms and cycle detection strategies and find the best combinations. One of out discoveries is that a cycle detection strategy of Tarjan greatly improves computational performance of a classical shortest path algorithm, making it competitive with the fastest known algorithms on a wide range of problems. As a part of out study, we develop problem families for testing negative cycle algorithms.
