Assessing Organizational Adoption of Information Systems Outsourcing

The information systems outsourcing (ISO) field continues to grow, as organizations consistently seek improvements in IT activities. The global scope of outsourcing participation and growth leads to gaps of knowledge related to the contextual factors that influence ISO adoption. Using the technology-organization-environment (TOE) framework, this study identifies and contextualizes the determinants of ISO adoption. Data collected from 261 firms suggest that relative advantage, firm size, top management support, and competitive pressure are the main determinants of ISO. This study highlights the importance of assessing ISO using the TOE theoretical lens, and offers replication of prior results, the lack of which is a growing concern in social science research.     

Is Petrobras Options Market Efficient? A Study Using the Delta-Gamma Neutral Strategy

This study aims to verify if the Petrobras options market is efficient in its weak form. For this purpose, this work tries to make profits on a systematic basis through delta-gamma neutral strategies using the firm’s stocks and options. In order to simulate the strategy as it would be used in the real world, we built order books every five minutes considering all buy and sell orders sent for both the underlying asset and its options. We apply the strategy when we observe distortions between implied volatilities extracted from the options. The results show evidence that the Petrobras options market is not efficient, since in 371 day-trade transactions (with an average investment of R$81,000 and an average holding time of one hour and thirteen minutes), 85% of the options strategies were profitable and the average return was 0.49%, which corresponds to more than 1600% of the highest interbank interest rate for the period.     

A two‐sector neo‐Kaleckian model of growth and distribution: Investment allocation and evolutionary dynamics

This paper focuses on the two‐sector neo‐Kaleckian model of growth and distribution that was developed by Dutt (1990) and challenged by Park (1995). We develop a variant of this model, focusing on the supply‐side to solve the overdetermination problem that was raised by Park. Finally, we introduce evolutionary dynamics to model the investment flows between the capital and consumer goods sectors. In this setup, the sectoral profit rates and the size of capital stocks wield an essential role upon the entrepreneur’s decision on which sector to invest in. This model is perfectly determined and it generates a stable evolutionary equilibrium over the long term.     

Organizational culture and post-acquisition changes in management control systems: An analysis of a successful Brazilian case

This paper analyzes the effect of organizational culture on the post-acquisition management control system (MCS) of the Brazilian company Extrativa Metalquímica Inc. after its acquisition by the FASA Participações Group. The results herein reported add to discussions of the subject and contribute to reducing the research gap in this area in Brazil. The analysis supports two major conclusions: (1) changes in the acquired company's MCS were derived from the new financial results-oriented culture introduced by the acquirer; and (2) the implementation of this culture implied modifications in production, financial and quality controls.     

The Impact of Cognitive and Noncognitive Skills on Professional Salaries in An Emerging Economy,Chile

Professional salaries in Chile are here explained on the basis not only of traditional human capital variables but also of variables indicative of other cognitive and noncognitive skills. As might be expected, college entrance scores (SAT), our measure of advanced cognitive skills, are found to impact strongly and nonlinearly on salaries. More surprisingly, ranking in one's high school graduation class raises one's salary 10 years later by the equivalent of one year of additional experience, suggesting that ranking stands for a more permanent noncognitive skill such as effort or self‐discipline. As is typically found, women earn less than men, but, to our surprise, they also have lower asking salaries than men.
