Revisiting the trans-situationality of values in Schwartz’s Portrait Values Questionnaire

Quality & Quantity - Schwartz in his famous theory of basic values follows Parsons and Rokeach in arguing that human values are trans-situational or context free. For any individual, the same...     

Contratos de riesgo de petróleo,patrones de conducta y desempeño de empresas: Análisis de panel de datos

Using data from financial and economic performance of International Oil Companies (IOCs) in the exploration-extraction (E&E) business, along with institutional and market orientation of governments and National Oil Companies (NOCs) that receive project offers, the international E&E market is analyzed in both institutional development and behavioral patterns of type of E&E contract following an agency theory approach. Additionally, given Mexico's recent energy reform being launched between 2015 and next 2019, the various types of E&E contracts are analyzed, comparing license contracts with production sharing and risk service ones. Next, using panel data methods an analysis of 17 enterprises between 2005 and 2015 is presented, where so-called global IOCs show higher returns and commitment than specialized ones, demonstrated by their net income and return on equity, or ROE.     

Temporary Migration and Foreign Direct Investment

The question of complementarity or substitutability of FDI and international labour mobility has not yet been answered. The substitutability assumption does not take into consideration the technological spillover of FDI in the host countries. Moreover, migration flows reveal cultural characteristics and labour force properties of their native country which may stimulate bilateral business networks, strengthening the complementarity assumption between capital and labour flows. In this paper we build a continuous time dynamic model where these offsetting forces are at work. We analyze whether, and to what extent, the increase in labour mobility might affect FDI outflows. A numerical simulation is performed showing that a higher income growth rate corresponds to a higher labour mobility. Some policy implications and further research direction are suggested.     

Pricing real options under the constant elasticity of variance diffusion

Much of the work on real options assumes that the underlying state variable follows a geometric Brownian motion with constant volatility. This paper uses a more general assumption for the state variable process that better captures the empirical regularities found in commodity markets. We use the constant elasticity of variance diffusion, where volatility is a function of underlying asset prices, and we provide analytic solutions for perpetual American options. We show that a firm that uses the standard lognormal assumption is exposed to significant errors of analysis, which may lead to nonoptimal investment and disinvestment decisions. © 2010 Wiley Periodicals, Inc.

Interest Rate Derivatives in a Duffie and Kan Model with Stochastic Volatility: An Arrow-Debreu Pricing Approach

Simple analytical pricing formulae have been derived, by different authors and for several derivatives, under the Gaussian Langetieg (1980) model. The purpose of this paper is to use such exact Gaussian solutions in order to obtain approximate analytical pricing formulas under the most general stochastic volatility specification of the Duffie and Kan (1996) model. Using Gaussian Arrow-Debreu state prices, first order stochastic volatility approximate pricing solutions will be derived only involving one integral with respect to the time-to-maturity of the contingent claim under valuation. Such approximations will be shown to be much faster than the existing exact numerical solutions, as well as accurate.     

How Useful Are the Strategic Tools We Teach in Business Schools?

Strategic tools are indispensible for business and competitive analysis. Yet we know very little about managers' internal logic as they put these tools into practical use. We situate our study in a business school context using action learning prior to the manifestation of practice to complement our understanding of practice. Using Personal Construct Theory and Repertory Grids, our mid‐range theorizing showed that, contrary to current thinking about strategic tools, managers think in dualities (often paradoxically) and have a preference for multiple‐tools‐in‐use, tools that provide different perspectives, peripheral vision, connected thinking, simultaneously help differentiate and integrate complex issues, and guide the thinking process. These findings are important for designing better tools and the nurturing of critical managerial competencies needed for a complicated world. Our study's focus also has wider implications for scholars as we see our own material evaluated by those who will put these lessons into practice.     

Intergenerational Altruism and the Environment

We construct an overlapping generations model of pollution externality in which individuals are altruistically linked to their offspring as in Barro (1974). It is shown that steady-state consumption may be a decreasing function of the intergenerational degree of altruism. Despite individuals' altruism, the competitive equilibrium is not optimal. We thus study the social optimum and show that it can be decentralized.

Dynamic Interplay of Visual and Textual Identification Strategies in Employees’ Magazines

This article explores how an organization’s identity is strategically communicated through texts and images in the employees’ magazines of a global Danish company with a worldwide readership of over 18,000 employees. Drawing on an interdisciplinary methodological framework related to organizational identification theory and social semiotics, it proposes a multimodal analysis model through which several identification strategies are explored at the level of each semiotic mode and at the level of their interplay. The article explains how identity is strategically communicated in accordance with the potential and constraints of texts and images. It claims that by exploring how these semiotic modes reinforce, complement or subvert each other, the identification strategies can be more thoroughly addressed. Shedding light on how the multimodal interplay contributes to communicate identity, this model can also be employed by communicators in order to nuance and improve their strategic communicative practice. By examining the semiotic modes’ complex interconnectivity and functional differentiation in the strategic communication of identity, this article expands the existing research work as the usual textual focus is extended to a multimodal one.
