Understanding and Improving Teamwork in Organizations: A Scientifically Based Practical Guide

Teams are pervasive in today's world, and rightfully so as we need them. Drawing upon the existing extensive body of research surrounding the topic of teamwork, we delineate nine “critical considerations” that serve as a practical heuristic by which HR leaders can determine what is needed when they face situations involving teamwork. Our heuristic is not intended to be the definitive set of all considerations for teamwork, but instead consolidates key findings from a vast literature to provide an integrated understanding of the underpinnings of teamwork—specifically, what should be considered when selecting, developing, and maintaining teams. This heuristic is designed to help those in practice diagnose team‐based problems by providing a clear focus on relevant aspects of teamwork. To this end, we first define teamwork and its related elements. Second, we offer a high‐level conceptualization of and justification for the nine selected considerations underlying the heuristic, which is followed by a more in‐depth synthesis of related literature as well as empirically‐driven practical guidance. Third, we conclude with a discussion regarding how this heuristic may best be used from a practical standpoint, as well as offer areas for future research regarding both teamwork and its critical considerations. © 2014 Wiley Periodicals, Inc.     

‘The Ethics of Managerial Subjectivity’

This paper examines ethics in organizations in relation to the subjectivity of managers. Drawing on the work of Michel Foucault we seek to theorize ethics in terms of the meaning of being a manager who is an active ethical subject. Such a manager is so in relation to the organizational structures and norms that govern the conduct of ethics. Our approach locates ethics in the relation between individual morality and organizationally prescribed principles assumed to guide personal action. In this way we see ethics as a practice that is powerfully intertwined in an individual’s freedom to make choices about what to do and who to be, and the organizational context in which those choices are situated, framed and governed.     

An Empirical Analysis of Tijuana Water Consumption

This paper examines time series characteristics of water consumption in Tijuana, a large manufacturing center and port city located in Northwestern Mexico. Home to more than 700 maquiladora assembly plants, it is one of the fastest growing metropolitan economies in Mexico. That growth places intense demands on the municipal water grid. Because it is located in a semi-arid region, Tijuana also faces supply constraints. Given the nature of the problems faced by water authorities, this research uses time series econometric techniques to analyze monthly information on grid hook-ups and per meter water consumption. Empirical estimation results are fairly satisfactory. Out-of-sample simulation results are mixed and indicate that care should be used if these equations are employed for planning purposes. Lag structures in the equations do, however, suggest several policy implications with respect to drought surcharges and rate hikes.      

Exchange Rate Policy and Liability Dollarization: What do the Data Reveal about Causality?

The paper identifies the contemporaneous relationship between exchange rate policy and liability dollarization using three different definitions of dollarization. The presence of endogeneity makes the empirical identification elusive. We use identification through heteroskedasticity to solve the endogeneity problem in the present context ( Rigobon, 2003 ). While we find that countries with high liability dollarization (external, public, or financial) tend to be more actively involved in exchange rate stabilization operations, we do not find evidence that floating, by itself, promotes de‐dollarization.     

Project Manager Profile Characterization in the Construction Sector in Bogotá, Colombia

This study aims to describe and evaluate the characteristics (educational background, training, skills, and experience) that make up the project manager profile in the construction sector in Bogotá, Colombia. This study is based on a project management literature review, expert interviews and surveys with a group of project managers in the construction sector, and comparisons between them. This evaluation aims to contribute to the development of a clearer de?nition of the project manager profile in the Colombian context. The identified project manager profile satisfies the essential desired characteristics with some particular weaknesses related to education and training in project management.     

Asymmetric labor supply

The estimation of labor supply elasticities has been an important issue in the economic literature. Yet all works have estimated conditional mean labor supply functions only. The objective of this paper is to obtain more information on labor supply, estimating a conditional quantile labor supply function. We use a sample of prime age urban males employees in Brazil. Two stage estimators are used as the net wage and nonlabor income are found to be endogenous to the model. Contrary to previous works using conditional mean estimators, it is found that labor supply elasticities vary significantly and asymmetrically across hours of work. While the income and wage elasticities at the standard work week are zero, for those working longer hours the elasticities are negative.     

Estimation of conditional time-homogeneous credit quality transition matrices

This paper presents a methodology for estimating time-homogeneous credit quality transition matrices. Using a unique data set on credit ratings of commercial loans in Colombia, we show that 70% of the time we cannot reject the null hypothesis of time homogeneity of transition matrices estimated this way. We also find that obtaining matrices for different subsamples is not necessary, given the similarities of the survival functions.     

The evolving role of large and medium farms on Brazilian agriculture

We use Brazilian agricultural censuses data since 1970 to describe land structure evolution in Brazil, focusing on the most important agricultural commodities and livestock products across regions. The analysis reveals a remarkable stability in the number of farms in the period, as well as in the structure of land distribution across farm sizes, with a persistence of a dual agricultural structure. Land distribution, as measured by the GINI index, has changed very little and is still very high. The number of large farms is increasing significantly in time, while the number of farms with area below 500 ha changed little in the 1970–2006 period. Medium‐sized and large farms, although heavily outweighed in numbers, account for the highest share of annual crop production currently, and their share in crop (annual plus permanent) production value increased between 1980 and 2006, while the same share decreased for smaller farms. We conclude that the observed stability will probably reduce in the future, as economic forces will likely change the balance in favor of an increase in the number of large farms. This is an issue of obvious political importance, especially considering the importance of the smaller farms for employment in agriculture.
