Abstract: This paper studies the problem of weak no-arbitrage in a frictional market with transaction costs and bid-ask spreads.By using convex analysis and nonlinear programming,a fundamental characterization of weak no-arbitrage and a series of results related to state prices and weak no-arbitrage are established.These results extend many known results in existing literature.

Key words: weak no-arbitrage, frictional markets, transaction costs, bid-ask spreads
