Computation of Arbitrage in a Financial Market with Various Types of Frictions

چکیده
In this paper we study the computational problem of arbitrage in a frictional market with a finite number of bonds and finite and discrete times to maturity. Types of frictions under consideration include fixed and proportional transaction costs, bid-ask spreads, taxes, and upper bounds on the number of units for transaction. We obtain some negative result on computational difficulty in general for arbitrage under those frictions: It is NP-complete to identify whether there exists a cash-and-carry arbitrage transaction and it is NP-hard to find an optimal cash-and-carry arbitrage transaction.

Computation of arbitrage in frictional bond markets
In this paper we study the computational problem of arbitrage in a frictional market with a finite number of bonds and finite and discrete times to maturity. Types of frictions under consideration include fixed and proportional transaction costs, bid–ask spreads, taxes, and upper bounds on the number of units for transaction. We develop a necessary and sufficient condition for the existence of ...
متن کاملOn Computation of Arbitrage for Markets with Friction
We are interested in computation of locating arbitrage in financial markets with frictions. We consider a model with a finite number of financial assets and a finite number of possible states of nature. We derive a negative result on computational complexity of arbitrage in the case when securities are traded in integer numbers of shares and with a maximum amount of shares that can be bought fo...
متن کاملNecessary 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...

Financial markets are one of the most fundamental markets in any country. In the financial markets, the securities market and the foreign exchange market are sensitive sectors. These two markets are affected by fluctuations and economic cycles so reflect economic changes rapidly. Changes in the returns of one market due to arbitrage conditions during time lead to changes in the returns of other...

The literature on Foreign Direct Investment (FDI) has advanced several explanations of the links between financial market developments and FDI inflows across developing as well as developed countries. Empirical literature show that financial market development reduces informational frictions and improves resource allocation more efficiently. Also, financial systems are important for both produc...
