Gender and Labor Attachment: Do Within‐Firms’ Relative Wages Matter?

This article addresses the issue of gender differences in labor attachment by testing for the role of intrafirm wage comparison. It makes use of a measure of firms' relative wages. The results indicate that once the forward-looking behavior of workers is taken into account, women are actually more attached employees than men. Women's attachment is also more affected by equity considerations. The analysis makes use of a dataset on short-tenure Italian workers.     

Demand chain management: an integrative approach in automotive retailing

Recent reviews of the ‘operations management’ (OM) research literature have shown a surprising little shift towards empirical methodologies from traditional modelling solution methods. In addition, there is generally a lack of empirical testing and validation of manufacturing strategies. Coupled to this fact is that empirical work is rarely carried out in an inter-disciplinary manner, with the complete combination of OM, marketing, strategy, lean thinking and accounting approaches particularly poorly researched. Fully cross-functional integrative empirical research is required to help support the understanding of the applicability of OM practices within industry. This paper explores such an integration of approaches developed within the ‘lean thinking, strategic cost management, marketing and policy deployment areas’. In order to investigate the approach a single automotive retailer is used as an instrumental case. The results of the study show that the new approach stands up well as an integrative approach that can prove highly beneficial results. However, the pilot work also identified a number of limitations that are the basis of further refinement and testing of the method.     

Incumbents in a dynamic Internet related services market: Does customer and competitive orientation hinder or help performance?

The Internet challenges many incumbent firms to adapt their marketing strategies by developing and offering new products involving Internet technology. Existing literature on market orientation and performance of services suggests that market orientation, and its components, are likely to facilitate effective adaptation. In contrast, the marketing innovation literature suggests market orientation may be too reactive and inhibit effective adaptation. Our results suggest some merit to both perspectives. Client orientation hindered performance of Internet advertising services, while competitive orientation facilitated performance. In addition, limited support was found that suggested superior performance occurs in an environment with a diverse client base and clients possessing in-house capabilities that “compete” with agencies for Internet advertising services. Implications for incumbents pursuing product growth strategies via new, technology related services in dynamic environments are discussed.     

Evolution in the rationales of foresight in Europe

The traditional mechanistic approach to Strategic Thinking influenced the rationales and consequently the early experiences of Technology Forecasting in Europe. On the other hand, the more recent dynamic non-linear approaches to Strategic Thinking and a gradual regionalization of the innovation policy have favoured the replacement of Forecasting with Foresight and, more recently, with Regional Foresight, where the complexity of phenomena is taken into greater account. In fact, during the last few decades, a transition has occurred from a mainly hierarchic capitalism to a flexible one. At micro-economic level, this has caused a gradual transition from hierarchical organisational models with tangible assets to network organisational models, which are knowledge-based and face complex and unsettled scenarios.

This paper tries to demonstrate that the concepts of Forecasting and Foresight cannot be considered outside of this context and of changes that have occurred in Strategic Thinking, where the needs for more global and interdisciplinary views of problems are striving to integrate Strategic management and Entrepreneurship into the new concept of Strategic Entrepreneurship.

In order to demonstrate this evolution in the rationales of foresight and in its applications, this work analyses and compares some among the more significant experiences of transition towards Regional Foresight in Europe.     

Economic valuation of environmental services sustained by water flows in the Yaqui River Delta

We attempted to estimate the economic value of environmental services provided by restored instream flows in the water-scarce Yaqui River Delta in Mexico. The Yaqui River begins near the U.S.-Mexico border and continues for 400 km before reaching the Oviachic dam, but has not reached the nearby Gulf of California for decades due to diversions for irrigation. These diversions have degraded the riparian ecosystem, coastal wetlands, and estuaries. Environmental services provided by restored flows in the Yaqui River would include healthy riverside vegetation, wetlands and estuaries, fish and wildlife habitats, non-use values, and recreation. A contingent valuation survey in 40 neighborhoods in the most populated Delta city, Ciudad Obregon, was administered to estimate non-market values of instream uses. Respondents were given a current and hypothetical Delta scenario (the latter assumed restored water flows in the River) and asked a willingness-to-pay (WTP) question regarding purchasing water for environmental flows through higher water bills. Results from 148 in-person interviews indicated that households would pay an average of 73 pesos monthly. WTP was found related to key variables suggested by economic theory and contingent valuation studies elsewhere: income, educational level, number of children in the household, and initial bid amount. These results will allow decision makers to compare the benefits generated by different water uses, including environmental services, and to manage scarce water resources under a long-term sustainable approach.     

Modelling the effect of climate change on prevalence of malaria in western Africa

Malaria is a leading cause of infectious disease and death worldwide. As a common example of a vector‐borne disease, malaria could be greatly affected by the influence of climate change. Climate impacts the transmission of malaria in several ways, affecting all stages of the disease's development. Using various weather‐related factors that influence climate change, this study utilizes statistical analysis to determine the effect of climate change on reported malaria rates in an African region with endemic malaria. It examines the relationship between malaria prevalence and climate in western Africa using spatial regression modeling and tests for correlation. Our analysis suggests that minimal correlation exists between reported malaria rates and climate in western Africa. This analysis further contradicts the prevailing theory that climate and malaria prevalence are closely linked and negates the idea that climate change will increase malaria transmission in this region.     

Discretionary and transactional human resource practices and employee outcomes: The role of perceived organizational support

Utilizing perceived organizational support (POS) as the mechanism linking HR practices to employee behaviors in the workplace, we examine a broad set of HR practices in order to understand the relative importance of each HR practice (i.e., those that explain incremental variance over other practices) in influencing employee behaviors. We differentiate between discretionary and transactional HR practices to test the discretionary investment requisite of POS theory. The results show that of the eight discretionary practices, only participation and decision making directly influenced the extra‐role behaviors that employees exhibit, and only training and development directly impacted the customer‐oriented behaviors. Furthermore, one of the transactional HR practices was found to have a direct effect on organizational citizenship behavior. Our findings indicate that the performance management process, promotional opportunities, participation, and involvement in decision making affect how employees behave toward the customer and the extra‐role behaviors they exhibit. Furthermore, this occurs through the view employees develop of the organization as a place to work. That is, these four HR practices demonstrate to employees that they are valued, and, in turn, this feeling of being appreciated impacts their commitment to delivering high‐quality service to the customer and going beyond their job responsibilities. Implications for research and practice are discussed. © 2012 Wiley Periodicals, Inc.     

Mitigating Natural Disasters through Collective Action: The Effectiveness of Tsunami Early Warnings

The megathrust earthquake centered near Sumatra on December 26, 2004, generated a tsunami that resulted in an estimated 150,000 deaths in Indonesia alone. In response, commitments have been made to extend the existing tsunami early warning systems in the Pacific to the remainder of the world subject to tsunamis. Surprisingly, while these systems have been in place in some cases for more than half a century, to date no analysis of their effectiveness has been presented. We fill this research gap by analyzing 146 out of the 202 tsunamis occurring worldwide since 1966. Relying on a negative binomial regression model that controls for the dynamics of the tsunami, we find early warnings to be quite effective in reducing deaths. The model also controls for additional factors important in determining a tsunami's death toll such as socioeconomic conditions, which have been shown to be important in other natural disasters.     

Specification Analysis of Diffusion Models for the Italian Short Rate

In recent years, diffusion models for interest rates became very popular. In this paper, we perform a selection of a suitable diffusion model for the Italian short rate. Our data set is given by the yields on 3‐month BOT (Buoni Ordinari del Tesoro), from 1981 to 2001, for a total of 470 observations. We investigate among stochastic volatility models, paying more attention to affine models. Estimating diffusion models via maximum likelihood, which would lead to efficiency, is usually unfeasible because the transition density is not available. Recently, Gallant and Tauchen (1996) proposed a method of moments which gains full efficiency, hence its name of Efficient Method of Moments (EMM); it selects the moments as the scores of an auxiliary model, to be computed via simulation; thus, EMM is suitable to diffusions whose transition density is unknown, but which are convenient to simulate. The auxiliary model is selected among a family of densities which spans the density space. As a by‐product, EMM provides diagnostics that are easy to compute and interpret. We find evidence that one‐factor models and multi‐factor affine models are rejected, while a logarithmic specification of the volatility provides the best fit to the data .     

Push and pull factors and Hispanic self-employment in the USA

This study examines the main push and pull factors driving Hispanic self-employment in the USA by modeling the self-employment decision as a function of sectoral earnings differences, country of origin, and other factors. Findings indicate that a main reason Hispanics engage in self-employment is they can earn more working for themselves than in wage/salary work. Immigrants appear to be pushed into self-employment as a result of limited opportunities in the wage work sector. Although low relative earnings in wage/salary work could push workers with limited English proficiency into self-employment, our findings indicate barriers to this. Results suggest that workers pulled into self-employment are those with more work experience and a college degree. Workers who originate from Southern South America and Colombia have relatively high self-employment rates, while Mexico-origin workers have relatively low self-employment rates. We also uncover differences across Hispanic origin groups in terms of the influence of gender, education, and personal wealth on self-employment participation.
