Simulador de vuelo ejecutivo como medio de aprendizaje en la planeación de recursos de nuevas empresas bajo el enfoque del marcador balanceado

A deficient strategic planning in new companies has produced that entrepreneurs initial decisions haven’t been the appropriate and, in the long term, consequences will be reflected in the failure of many new companies. The objective of this article is to propose an executive flight simulator that will help to identify and evaluate different strategies for the development of resources of a new manufacturing company, based on the four perspectives of the balanced scorecard that will help the user to become sensitive in the impact that this will have in the performance measures. The simulator is designed under the System Dynamics view for educational purposes in MBAs, entrepreneurship or executive development programs.     

The emergent role of value representation in managing business relationships

This paper explores value processes, their effects, and their management in business relationships. Over time, scholars progressively moved their interest from the value of the objects exchanged to the value of business relationships. However, how value is related to interactive processes that characterize business relationships still remained unclear. With this scope, the paper brings to the fore recent studies on the role of actors' perceptions of value and the interactive features of the business context. The empirical research involves 77 interviews carried out over two years with actors internal and external to the Mikron Tool's business network, a Swiss leader in manufacturing high-precision tools. The study shows that four key value processes – value creation, value communication, value measurement, and value appropriation – determine specific consequences that must be managed to achieve effective business relationships. Moreover, empirical evidences highlight the relevance of value representation in affecting the four value processes. The study contributes to an improved understanding of value management in interactive and interdependent business contexts. Also, it draws attention to the need for a better integration between the traditional economic view of value and recent insights from the fields of organizational psychology and sociology.     

Robust design in multivariate systems using genetic algorithms

This paper presents a methodology based on genetic algorithms, which finds feasible and reasonably adequate solutions to problems of robust design in multivariate systems. We use a genetic algorithm to determine the appropriate control factor levels for simultaneously optimizing all of the responses of the system, considering the noise factors which affect it. The algorithm is guided by a desirability function which works with only one fitness function although the system may have many responses. We validated the methodology using data obtained from a real system and also from a process simulator, considering univariate and multivariate systems. In all cases, the methodology delivered feasible solutions, which accomplished the goals of robust design: obtain responses very close to the target values of each of them, and with minimum variability. Regarding the adjustment of the mean of each response to the target value, the algorithm performed very well. However, only in some of the multivariate cases, the algorithm was able to significantly reduce the variability of the responses.     

Stationarity without degeneracy in a model of commodity money

We develop a model of macroeconomic heterogeneity inspired by the Kiyotaki–Wright (J Polit Econ 97:924–954, 1989) formulation of commodity money, with the addition of linear utility and idiosyncratic shocks to savings. We consider two environments. In the benchmark case, the consumer in a meeting is chosen randomly. In the auctions case, the individual holding more money can be selected to be the consumer. We show that in both environments socially optimal trading decisions (that are individually acceptable) are stationary and solve a tractable static optimization problem. Savings decisions in the benchmark case are remarkably invariant to mean-preserving changes in the distribution of shocks. This result is overturned in the auctions case.     

Board Independence and Internal Committees in the BRICs

To be successful in global markets, companies from the emerging countries need the approval of foreign investors and other stakeholders. In this regard, Brazil, Russia, India, and China （BRIC） have progressively strengthened their corporate governance rules to help their companies overcome the competitors from the old industrialized countries. Directors＇ non-executive qualification, independence, and professional expertise represent basic requirements for effective corporate governance, so they should be carefully considered to guarantee a proper board composition and an adequate establishment of internal committees in listed companies. The paper intends to compare the legislative and regulatory frameworks adopted by the four countries; then it aims at answering to the following research questions by means of an empirical investigation： Have BRIC companies appointed non-executive and independent board members？ What do BRIC companies do in order to assure an effective participation of non-executive and independent board members to corporate governance activities？ Have BRIC companies established internal committees？ The research examines the appointment of non-executive directors and independent directors to the boards of 100 BRIC leading firms, as well as their involvement in internal committees focused on matters requiring motivated and impartial opinions. Although the laws and recommendations seem to favor a general convergence of corporate governance principles among the four BRIC and towards the international best practices, some differences and peculiarities emerge from a firm-level perspective. Indeed, the Indian and the Chinese companies analyzed appear more inclined than the Brazilian and the Russian ones to reassure their international stakeholders about board independence and effective committees.     

The joint continuity of the expected payoff functions

Glicksberg [Glicksberg, I.L., 1952. A further generalization of the Kakutani fixed point theorem, with applications to Nash equilibrium points. In: Proceedings of the American Mathematical Society 3, pp. 170–174] generalized the Kakutani fixed point theorem to the setting of locally convex spaces and used it to prove that every k-person strategic game with action sets convex compact subsets of locally convex spaces and continuous payoff functions has a Nash equilibrium. He subsequently used this result to establish the following fundamental theorem of game theory: Every k-person strategic game with action sets metrizable compact topological spaces and continuous payoff functions has a mixed strategies equilibrium. However, in his proof of the latter result, Glicksberg did not show that the expected payoff functions were jointly continuous, something that was required for the existence of a mixed strategies equilibrium.     

Pigou on philosophy and religion

Abstract

This article discusses a group of essays on ethical issues written by Pigou between 1900 and 1908. It is argued that they contain the foundations of his economic philosophy. Pigou's research on the meaning and content of the good merged into his definition of welfare, and his interest in religion as a subjective experience resurfaced in the subjective framework of his economics. A methodological pragmatism informed his economics as well as his ethics; moreover, the endorsement of interpersonal comparisons of the good in the ethical texts was consistent with Pigou's adoption of utility comparisons in welfare economics. Pigou's philosophical pessimism was reflected in his analysis of the economic evils of society, eventually leading to his advocacy of governmental intervention to foster economic welfare. The article contends that Pigou's philosophy derived not only from Sidgwick, as commonly believed, but also from G.E. Moore's Principia Ethica.     

The new IMF approach to capital account management and its blind spots: lessons from Brazil and South Korea

As emerging economies experience a boom in capital inflows, governments are increasingly concerned about their downsides. Even the IMF (International Monetary Fund), long a stalwart proponent of financial liberalization, has engaged in a new debate on capital flow management. Drawing lessons from empirical case studies on Brazil and South Korea, this paper finds that the new IMF framework remains insufficient in two main aspects. First, by defining ‘capital flow management measures’ (CFMs) as a temporary instrument embedded in an overall strategy of financial opening, the organization insists on the general advantages of financial liberalization, which poses serious limits to emerging economies’ policy space. Second, the Fund keeps on stressing a separation of prudential financial regulation, which should be permanent, and temporary CFMs. Yet, the case studies presented here show that, especially for emerging markets with rather open and sophisticated domestic financial markets, both types of measures are interdependent and overlapping. Additionally, we demonstrate the relevance of a third type of regulation, lying on foreign exchange (FX) derivatives instruments, which may also be required to effectively manage foreign investors’ portfolio reallocations and their impact.     

Sequential Markets: An Experimental Investigation of Clower's Dual-Decision Hypothesis

Countless experimental studies have shown that markets converge quickly and efficiently to the competitive outcome under many trading institutions, particularly the double auction mechanism. This creates difficulties for Keynesian stories of unemployment creation—which suggest a noncompetitive outcome in an essentially competitive world. Such stories were popular in the late 1960s and 1970s. One of these stories—the dual decision hypothesis of Clower—was seen then as the beginning of a story of unemployment. This article reports the results of an experiment designed to test this hypothesis. Specifically, we set up an experiment in which there are two sequential double-auction markets, in the first of which one good (labour) is traded, after which the second market (goods) is opened and the second good traded. We compare the outcome of our experiment with that of the competitive theory. One general finding is that not enough trade takes place in the two markets. In other words, the usual finding that competitive equilibrium is achieved in double-auction markets is not replicated in this sequential setting.
