A Unified Approach to Portfolio Optimization with Linear Transaction Costs

2004

In this paper we study the continuous time optimal portfolio selection problem for an investor with a finite horizon who maximizes expected utility of terminal wealth and faces transaction costs in the capital market. It is well known that, depending on a particular structure of transaction costs, such a problem is formulated and solved within either stochastic singular control or stochastic impulse control framework. In this paper we propose a unified framework, which generalizes the contemporary approaches and is capable to deal with any problem where transaction costs are a linear/piecewise-linear function of the volume of trade. We also discuss some methods for solving numerically the p…

El componente de selección adversa de la horquilla de precios cotizada: una revisión de los modelos de estimación

2005

-Jose.E.Farinos@uv.es -Ana.M.Ibanez@uv.es Una de las principales preocupaciones en el área de la microestructura del mercado ha sido la estimación de los componentes no observables de la horquilla de precios a partir de las series de datos que proporcionan los mercados financieros, despertando quizá un mayor interés el de selección adversa por la implicaciones que supone la existencia del mismo. Esto ha provocado el desarrollo de numerosos modelos empíricos que, basándose en las propiedades estadísticas de las series de precios, proporcionan dichas estimaciones. La mayor disponibilidad de datos existentes en los mercados ha permitido el desarrollo en los últimos años de modelos basados en t…

Impact of e-government on transaction cost and FDI inflows: A proposed conceptual framework

2011

Published version of an article in International Journal of Business and Management, 6(11), 285-296. Also available from the publisher at http://dx.doi.org/10.5539/ijbm.v6n11p285 Although vast normative e-government literature supports the assertion that implementation of e-government reduces transaction cost and promotes Foreign Direct Investment; empirical evidence to support this thesis is limited. Even more, there is limited attempt when studying this phenomenon to integrate e-government literature with other literatures in which major constructs of interest are rooted. This article contributes to reducing this gap by establishing a conceptual framework that integrates e-government lite…

European Option Pricing and Hedging with Both Fixed and Proportional Transaction Costs

2003

Abstract In this paper we provide a systematic treatment of the utility based option pricing and hedging approach in markets with both fixed and proportional transaction costs: we extend the framework developed by Davis et al. (SIAM J. Control Optim., 31 (1993) 470) and formulate the option pricing and hedging problem. We propose and implement a numerical procedure for computing option prices and corresponding optimal hedging strategies. We present a careful analysis of the optimal hedging strategy and elaborate on important differences between the exact hedging strategy and the asymptotic hedging strategy of Whalley and Wilmott (RISK 7 (1994) 82). We provide a simulation analysis in order …

European Option Pricing with Transaction Costs and Stochastic Volatility: an Asymptotic Analysis

2015

In this paper the valuation problem of a European call option in presence of both stochastic volatility and transaction costs is considered. In the limit of small transaction costs and fast mean reversion, an asymptotic expression for the option price is obtained. While the dominant term in the expansion it is shown to be the classical Black and Scholes solution, the correction terms appear at $O(\varepsilon^{1/2})$ and $O(\varepsilon)$. The optimal hedging strategy is then explicitly obtained for the Scott's model.

Inter-organizational networks and innovation in small, knowledge-intensive firms: A literature review

2013

Published version of article from the journal: International Journal of Innovation Management In this study, we address the effect of innovation strategy and an innovative working climate on financial performance in the Norwegian wood industry. Innovation strategy embodies four dimensions: the degrees to which innovation in the form of products, processes, and business systems are embedded in the management values and priorities as well as the degree of expenditure in R&D. An innovative working climate is exemplified by team cohesion, supervisory encouragement, resources, autonomy, challenge, and openness to innovation. Previous studies have indicated a lack of research in traditional manuf…

Portfolio optimisation with strictly positive transaction costs and impulse control

1998

One crucial assumption in modern portfolio theory of continuous-time models is the no transaction cost assumption. This assumption normally leads to trading strategies with infinite variation. However, following such a strategy in the presence of transaction costs will lead to immediate ruin. We present an impulse control approach where the investor can change his portfolio only finitely often in finite time intervals. Further, we consider transaction costs including a fixed and a proportional cost component. For the solution of the resulting control problems we present a formal optimal stopping approach and an approach using quasi-variational inequalities. As an application we derive a non…

E-Government in Marketing a Country: A Strategy for Reducing Transaction Cost of Doing Business in Tanzania

2011

Published version of an article in International Journal of Marketing Studies, 3(4), 2-16. Also available from the publisher at http://dx.doi.org/10.5539/ijms.v3n4p2 There are limited studies examining the role of Investment Promotion Agencies (IPA’s) and their respective marketing techniques used in attracting Foreign Direct Investment (FDI). Using an exploratory case study approach, this article addresses this research gap by exploring the role of e-government as a promotion technique in eliminating barriers to FDI inflows in Tanzania; particularly barriers related to information accessibility and bureaucratic procedures facing foreign investors in acquiring relevant licenses and business…
