Asymptotic analysis for Merton's problem with transaction costs in power utility case [PDF]
arXiv, 2013 We revisit the optimal investment and consumption problem with proportional transaction costs. We prove that both the value function and the slopes of the lines demarcating the no-trading region are analytic functions of cube root of the transaction cost parameter.

From Nature to Engineering: Mortar Volume and Interfacial Mechanics in Bioinspired Ceramics
Advanced Engineering Materials, EarlyView.Inspired by natural armors like nacre, this study explores how varying the volume fraction of the soft mortar layer impacts the interfacial strength and toughness of bioinspired ceramics. Experimental and computational analysis reveals that higher mortar volumes increase energy dissipation but reduce interfacial stiffness, offering insights for ...

Why Transaction Cost Economics Failed and How to Fix It [PDF]
arXivThe connotation of transaction costs has never been definitively determined, and the independence of the concept has never been rigorously demonstrated. This paper delves into the thought systems of several prominent economists in the development of transaction cost economics, starting from first-hand materials.

Advanced Engineering Materials, EarlyView.Ni‐base superalloys produced using additive manufacturing (AM) have a different response to heat treatments when compared to their conventional counterparts. Due to such unpredictability, various alloys with industrial interest are currently overlooked in most prior AM research.

Comparative Statics of Trading Boundary in Finite Horizon Portfolio Selection with Proportional Transaction Costs [PDF]
arXivWe consider the Merton's problem with proportional transaction costs. It is well-known that the optimal investment strategy is characterized by two trading boundaries, i.e., the buy boundary and the sell boundary, between which is the no-trading region. We study how the two trading boundaries vary with transaction costs.
