Airlines’ strategic interactions and airport pricing in a dynamic bottleneck model of congestion

This paper analyzes efficient pricing at a congested airport dominated by a single firm. Unlike much of the previous literature, we combine a dynamic bottleneck model of congestion and a vertical structure model that explicitly considers the role of airlines and passengers. We show that a Stackelberg leader interacting with a competitive fringe partially internalizes congestion, and that there are various toll regimes that induce the welfare maximizing outcome, widening the set of choices for regulators. In particular, charging the congestion toll that would apply for fully competitive carriers and that ignores any internalization, to both the leader and the fringe, yields the first-best outcome.     

Developing a ‘European’ model of human resource management

The concept of human resource management (HRM) has been much debated in the literature. Space limitations preclude an examination of that debate here, but it is clear that the concept developed initially from work in the United States of America in the 1960s and 1970s and since then has been adopted increasingly in the academic literature, by consultancy services and in organizational terminology. The terminology spread from the USA firstly into the developed English speaking world and recently - and more partially - into Europe. Is the concept, as opposed to the terminology, applicable in Europe? This paper argues that the organizational autonomy on which the subject is propounded in the United States is not espoused in Europe. A range of subject areas in which organizations in Europe are supported/constrained by external factors are analysed, thus challenging the validity of the American model. This raises the need to consider different conceptual approaches to HRM: a new model of the concept which would encompass EuroHRM is proposed.     

On the linearity of the wage–profit relation in a Sraffa’s model: a mathematical summing-up

This paper sums up in a common analytical structure the main results, scattered in economic literature, concerning the linearity between rate of profit and real wage in a simple Sraffa’s model. The paper is mainly based on previous results of one of the two authors and on results of Miyao (Int Econ Rev 18:151–162, 1977) and Schefold (Zeitschrift für angewandte Mathematik und Physik 27:873–875, 1976a; Zeitschrift für National?konomie 36:21–48, 1976b).

Impact of financial development on SAARC’S human development

The objective of the study is to investigate the link between economic growth and financial development (i.e., broad money supply, credit to private sector (CPS) and bank deposit liabilities) in human development for a panel of selected South Asian Association for Regional Cooperation (SAARC) countries; namely, Bangladesh, India, Nepal, Pakistan and Sri Lanka during 1988–2008; over the period of 1988–2008. The panel cointegration technique is employed for analysis of short and long-run relationship between the variables. The results of panel cointegration found that there is a long-run relationship between financial development indicators and economic growth in human development in SAARC region. The estimated results indicate that in the short run, bank deposit liabilities exerts the maximum impact (i.e., 0.425 %) on human development in SAARC region, subsequently, broad money supply (i.e., 0.301 %) and CPS (i.e., 0.128 %) respectively, while there is a negative relationship between real GDP growth and human capital (i.e., \(-\) 0.189 %). In the long-run, DOLS estimator constitutes broad money supply which increases by 0.912 %, followed by credit to private sector (i.e., 0.121 %) on human development. While, in case of FMOLS estimator, these results are disappear, as broad money supply does not have any significant impact on human development in SAARC region. The coefficient of real GDP per capita in both estimators, have a negative impact on human development, however, the intensity of both estimators are different in nature, as real GDP per capita decrease human development in FMOLS (i.e., \(-\) 0.828 %) and in DOLS estimators (i.e., 0.458 %). The results indicate that due to a low quality of human capital in SAARC region; the direct effect of economic growth becomes negative; however, financial development indicators act as an important driver for increase in human capital in SAARC region. The implications of present research relate to heightening the need for labor market reforms and making the educational system more flexible.     

Loan managers’ decisions and trust in entrepreneurs in different institutional contexts

Loan managers’ trust in entrepreneurs can be a useful tool for overcoming entrepreneurial firms’ opaqueness. Nevertheless, the possibility for loan managers to leverage trust can be affected by differences in the regulative institutions within the banks (type of bank) and by place-bound normative institutions (social context). By relying on semi-structured interviews and a survey of 450 bank-entrepreneur relationships, this study finds that a positive impact of trust in lending relationships is sensitive to different place-bound normative institutions and to the regulative institutions within the banks. The results are robust with respect to potential endogeneity issues.     

Trust in the supervisor and the development of employees’ social capital during organizational entry: a conservation of resources approach

Abstract

This article aims to understand how trust in the supervisor contributes to the development of employees’ social capital using Conservation of Resources theory as a theoretical framework and networking ability as an indicator of social capital development. We hypothesize that the relationship between newcomers’ trust in the supervisor and networking ability will be mediated by feedback seeking from the supervisor and moderated by emotional exhaustion. Based on a three-wave time-lagged study of newcomers (N = 224), we found trust in the supervisor to be indirectly and positively related to networking ability through the mediating influence of feedback seeking from the supervisor. In addition, feedback seeking interacted with emotional exhaustion in predicting networking ability such that it was more positively related to it at high levels of emotional exhaustion. The indirect relationship of trust to networking ability as mediated by feedback seeking was also stronger at high levels of emotional exhaustion. We discuss this study’s implications for our understanding of supervisors’ role and newcomers’ experience during entry, as well as for social capital research.     

The role of villages in households’ poverty exit: evidence from a multilevel model for rural Vietnam

Vietnam experienced a dramatic drop in overall poverty during the 90s. However, the poverty reduction showed substantial variation across households, villages and regions. Using a multilevel model on panel data from the rural sample of the Vietnam Living Standard Measurement Survey we demonstrate the important role of villages in household poverty exit dynamics. We also show how an analysis of village-level random effects predictions can help targeting of policies to reduce poverty.     

Validating an agent-based model of the Zipf׳s Law: A discrete Markov-chain approach

This study discusses the validation of an agent-based model of emergent city systems with heterogeneous agents. To this end, it proposes a simplified version of the original agent-based model and subjects it to mathematical analysis. The proposed model is transformed into an analytically tractable discrete Markov model, and its city size distribution is examined. Its discrete nature allows the Markov model to be used to validate the algorithms of computational agent-based models. We show that the Markov chains lead to a power-law distribution when the ranges of migration options are randomly distributed across the agent population. We also identify sufficient conditions under which the Markov chains produce the Zipf׳s Law, which has never been done within a discrete framework. The conditions under which our simplified model yields the Zipf׳s Law are in agreement with, and thus validate, the configurations of the original heterogeneous agent-based model.     

Does organizational culture play a role in the development of psychological distress?

The aim of this article is to analyze the extent to which organizational culture contributes to the symptoms of psychological distress in the workforce. Integrating organizational culture and work organization conditions makes it possible to examine how culture is associated with the various components of work organization conditions, and how these conditions might relate to symptoms of psychological distress in employees. Data from the SALVEO study were collected in 2009–2012 from a sample of 1824 individuals nested in 60 Canadian workplaces. Multilevel regression models were used to analyze the data. After controlling for individual and family characteristics, only group and rational cultures were associated with psychological distress, but both type of organization cultures were mediated by work organization conditions. Group culture is indirectly associated with lower levels of psychological distress since it favors lower levels of psychological demands and job insecurity. Rational culture is indirectly associated with higher levels of psychological distress because it favors higher psychological demand levels. The results obtained highlighted the importance of including variables relating to broader organizational context in models examining stress in the workplace.

Exploring the antecedents of born-global companies’ international development

In recent years the emergence of so-called born-global firms -firms which start their international activities from their start up- has challenged traditional theoretical assumptions about the incremental process of internationalization, giving birth to the development of a new stream of studies. In order to give a contribution to this area of studies, the purpose of this paper is to empirically test a model to explain how well some factors are able to explain the level of international development of born global companies. A mail survey was conducted within a sample of born-global Italian companies, belonging to the most representative industries for the Italian economy (metal products and machinery equipment; furniture; chemicals and food). Findings support the validity of a model including five significant predictors: uncertainty and dynamism in the firm’s industry, operating in niche-based industries, markets’ and segments’ knowledge held by the founder/managers, product innovation and firms’ innovativeness, access to networks. Findings are discussed and managerial implications are drawn.

Existence and transversality conditions for a general ‘unbounded-horizon’ model of the mining firm

This paper derives conditions under which optimal programs exist for a general model of the competitive or monopolistic mining firm. The model significantly extends and synthesizes previous formulations by including both resource extraction and discoveries of new reserves, with stock-dependent resource exploitation costs and incomplete resource exhaustion, endogenous technical innovation, and state-dependent resource demand. In addition, the analysis addresses complications arising from having optimal programs defined over an ‘unbounded horizon’, with the possibility of either a finite or infinite terminal time and a non-zero terminal (‘salvage’) valuation if the terminal time is finite. The necessity of the infinite-horizon transversality conditions also is established. The paper illustrates a strongly intuitive approach to existence questions for infinite-horizon or unbounded-horizon control problems, with weaker concavity and interiority assumptions than are often encountered in the literature.     

The effect of unethical behavior on trust in a buyer–supplier relationship: The mediating role of psychological contract violation

Research on trust in buyer–supplier relationships has tended to focus on the performance outcomes of a trusting relationship, as well as the processes that serve to build trust. Largely absent from the buyer–supplier literature is an in-depth examination of activities that break down trust, and the resulting effect on supplier trust in the buyer. The authors propose and test a model that evaluates psychological contract violations between a buyer and a supplier as a mediating variable of the effect of unethical activities on trust within a partnership. Survey data was collected from 110 tier one suppliers of major corporations in the state of Ohio. Our results show how a supplier's perception of a violation of the psychological contract either partially mediates or fully mediates the relationship between the buyers unethical activity and the suppliers trust in that buyer. We discuss how suppliers may demonstrate bounded ethicality when they overlook perceived unethical behaviors by the buyer.     

Consumers’ fluid milk consumption behaviors in TURKEY: an application of multinomial logit model

Although consumers’ fluid milk consumption behavior related to skim milk, low fat milk and whole milk have attracted a lot of attention in the last decade, relatively a few studies have examined the consumers’ unprocessed and processed fluid milk consumption. The objective of this study was to analyze consumers’ fluid milk consumption and preference in Turkey by using cross-sectional national survey data. The Chi-square test of independence and multinomial logit procedure were used to investigate the selected socioeconomic and demographic characteristics of consumers that determine households’ fluid milk consumption choices between unprocessed fluid milk, processed fluid milk and non-consumption choices. Empirical results indicate that unprocessed fluid milk preference is related positively to household size, number of children in family, household income, and age of housewife; and negatively to education level and employment status of housewife. On the other hand, processed fluid milk preferences are related positively to household income, number of children in households and education level of housewife and negatively to household size and age of housewife.     

Bouncing up: The development of women leaders’ resilience

Although there are preliminary indications that resilience is a key factor for women on their way to top leadership positions, research on this topic is scarce. To narrow this research gap, we applied an exploratory interview study focusing on the development of women leaders’ resilience. We conducted 25 biographical interviews with women in top leadership positions in medium and large companies listed in Germany. Through a qualitative content analysis, we identified three critical phases for the development of women leaders’ resilience—early life, early career, and upper leadership—as well as phase-specific resilience factors—i.e., individual, situational, and behavioral factors. We integrated these findings in a process model that provides insights into the interlinkages of the different phases and factors and can serve as a starting point for future research.
