Adapting and testing the Fama and French model,with some variations of company characteristics

We examine whether the Fama and French (1992) (F&F) model can be adapted to become a more versatile and flexible tool, capable of incorporating variations of company characteristics in a more dynamic form. For this, the risk factors are reconstructed at the end of each reading of monthly data. We argue that, over time, the evaluation of a company may change as a result of variations in its market price, size or book price, and we are aware that the F&F model does not accurately reflect these dynamics. Our results show that the adapted model is able to capture the behaviour of a greater number of stocks than the original F&F model and risk factors are more significant when building them through our procedure. In addition, we carry out these adaptations during a period of instability in financial markets.     

Network analysis of exchange data: interdependence drives crisis contagion

In this paper, we examine linear and nonlinear co-movements that appear in the real exchange rates of a group of 28 developed and developing countries. The matrix of Pearson correlation and Phase Synchronous coefficients have been used in order to construct a topology and hierarchy of countries by using the Minimum Spanning Tree (MST). In addition, the MST cost and global correlation coefficients have been calculated to observe the co-movements’ dynamics throughout the time sample. By comparing Pearson and Phase Synchronous information, a new methodology is emphasized; one that can uncover meaningful information pertaining to the contagion economic issue and, more generally, the debate surrounding interdependence and/or contagion in financial time series. Our results suggest some evidence of contagion in the Asian currency crises; however, this contagion is driven by previous and stable interdependence.     

Capital accumulation and welfare: a note

Diamond's neoclassical growth model with National Debt is reconsidered with respect to dynamic welfare considerations. Conditions under which capital deepening implies increasing welfare are dependent upon the stability of the steady state, the interest elasticity of savings, and the relationship between the marginal propensity to save and the elasticity of substitution in production.     

Currency substitution and the real exchange rate: the utility maximization approach

This paper studies the currency-substitution hypothesis with Rational Expectations in terms of a Sidrauski-type model where domestic and foreign money enter the utility function. It shows that, contrary to Liviatan (1981), the approach does not necessarily contradict Calvo and Rodriguez (1977). Furthermore, the impact of monetary stabilization policy is fully characterized with flexible and (pre-) fixed rates for an extension of Dornbusch and Mussa (1975). A brief analysis of the Optimal Quantity of Money is also provided.     

The Effects of Attitudes,Subjective Norms,Attributions, and Individualism–Collectivism on Managers’ Responses to Bribery in Organizations: Evidence from a Developing Nation

The goal of this study was to introduce a model explaining how managers’ attitudes, subjective norms, attributions, and the individualism–collectivism cultural dimension affect the way managers’ deal with employee bribery in organizations. Twenty-six internal and external attributions related to bribery were identified through a series of structured interviews with 65 subject matter experts. These attributions, together with the other variables in the model, were evaluated by 354 (n = 354) Ecuadorian managers. Hierarchical regression analyses indicated that attitudes and external attributions significantly predicted managers’ intentions to discipline employees who accepted a bribe. In addition, external attributions mediated the relationship between individualism–collectivism and intent to discipline corrupt employees. Implications for the management of bribery in Latin American organizations are discussed.     

Individual Performance in Turbulent Environments: The Role of Organizational Learning Capability and Employee Flexibility

Organizational learning capability (OLC) and employee flexibility help firms navigate the challenges faced by organizations operating in turbulent environments. OLC includes dimensions such as experimentation, risk taking, openness, dialogue, and participative decision making. Employee flexibility is considered a crucial tool for strategic human resource management in tackling environmental turbulence. Accordingly, we pose the following research question: how, and to what extent, is individual performance enhanced by OLC and employee flexibility in turbulent environments? The major impact that environmental turbulence has on change and flexibility requirements suggests that employee flexibility plays an important role in the impact OLC has on individual performance. However, we found no prior studies that explicitly analyzed this mediating function of employee flexibility. In this study, we tested three hypotheses that link OLC and individual performance, OLC and employee flexibility, and employee flexibility and individual performance. We applied a structural equation methodology, using partial least squares path modeling, to a sample of 174 academics at a Latin American university (a highly turbulent context). Our results show employee flexibility fully mediates the relation between OLC and individual performance given the presence of environmental turbulence. © 2015 Wiley Periodicals, Inc.
