Characterization of bidding behavior in multi-unit auctions

This paper considers a very general class of single or multi-unit auctions of indivisible objects. The model allows for interdependent values, multidiminensional types and any attitude towards risk. Assuming only optimal behavior, we prove that each bid is chosen in order to equalize the marginal benefit to the marginal cost of bidding. This generalizes many existing results in the literature. We use this characterization to obtain sufficient conditions for truthful bidding, monotonic best reply strategies and identification results for multi-unit auctions.     

Market entry of firms with different legal forms: an empirical test of the influence of institutional factors

Drawing upon institutional theory we develop a conceptual model and investigate the determinants of market entry for worker cooperatives, publicly traded and limited-liability companies. Our results show that formal institutional conditions (i.e., mercantile legislation) influence the start-up choice of entrepreneurs regarding the legal form of their new venture. In addition, we take into account the influence of informal institutional conditions (i.e., local corporate culture) on the market entry rate of firms with different legal structures. Findings show that, while market entry is sensitive to the general economic climate, entry rates of firms with a different legal structure respond differently to the same economic conditions.

Security in a sea of insecurity: job security and intention to stay among service sector employees in Turkey

This article examines the association between job security and intention to stay for those who are employed in Turkey. There is a high level of unemployment in the country and many workers there are concerned about their job security. Job security refers to the objective dimensions of continuous contract, working full-time hours and paid and unpaid overtime. Job security also refers to the subjective dimension of perceived job security. We surveyed 407 employees in banking and related sectors' call centres, five-star hotel front-line staff and airline cabin crews. Results show that objective dimensions of job security are not associated with intention to stay. However, perceived job security is significantly and positively associated with intention to stay. We recommend that human resource managers focus on the perceived job security aspect of employment to keep valuable employees with the company.     

Supervisor and coworker support: a source congruence approach to buffering role conflict and physical stressors

The buffering effects of supervisor support on the stressor–strain relationship have proven elusive in prior research (Beehr, Farmer, Glazer, Gudanowski and Nair (2003), ‘The Enigma of Social Support and Occupational Stress: Source Congruence and Gender Role Effects,’ Journal of Occupational and Health Psychology, 8, 220–231). We built on emerging work on source congruence and conservation of resource theory to test a series of hypotheses intended to clarify these mixed findings. Using a sample of 768 employees from 45 organizations in North America, results from moderated regression analyses, showed that the effects of supervisor support on the stressor–strain relationship depended on source congruence. In accordance with our predictions, although we found buffering effects for the physical stressors–strain relationship, we found a reverse buffering effect for the role conflict–strain relationship. These differential buffering effects did not emerge when considering coworker support. We discuss the implications of our results for shedding light on the mixed evidence regarding buffering work stressors reported in prior research.     

Pay level satisfaction and employee outcomes: the moderating effect of autonomy and support climates

The present study examined autonomy climate (AC) and support climate (SC) as moderators of the relationship between pay level satisfaction (PLS) and employee outcomes (i.e. job satisfaction, affective commitment and intention to stay). Survey data were collected from 5801 Belgian employees, representing 148 units. The hypotheses derived from distributive justice theory and from research on the meaning of money received partial support. Multilevel analyses revealed that AC buffered the negative effects of low PLS on all three outcomes, and that SC exacerbated the negative effects of low PLS on intention to stay. Theoretical and practical implications of this differential moderating effect are discussed.     

Consultation and communication in family businesses in Great Britain

Nationally representative data on family businesses are available in the 1998 Workplace Employee Relations Survey, alongside comparable information for other types of firms. We use these data to compare differences in the use of different consultation and communication procedures. We cover such practices as the use of direct communication schemes (e.g. briefings; the provision of information on financial performance to the workforce) as opposed to indirect methods such as the use of joint consultative committees. There is an a priori expectation in the literature that family-owned businesses are either more likely to use direct forms of communication (vis-à-vis indirect forms) or that they will not be involved in direct communication or consultation with their employees, and we test this using multivariate techniques. Finally, we consider whether the type of consultation/communication structure matters in terms of establishment performance, and what differences exist with respect to family-owned businesses. In particular, this paper tests if those firms that consult directly with staff, as opposed to those that consult through joint consultative committees or trade unions, have higher productivity and/or other measures of performance. Concurrently we test whether there are separate ‘family business’ effects or whether it is generally establishment size that ‘matters’, by estimating a model for family-owned and non-family-owned establishments. In general, our results show that not only do family-owned establishments have lower levels of communication and consultation, but, when the latter is present, this does not generally translate into greater economic benefits (as is the case in non-family-owned firms).     

An empirically-derived multidimensional measure of expatriate success: reconciling the discord

This paper examines the discord surrounding how expatriate success, or effectiveness, is defined. We review the many ways that success has been conceptualized and then seek to reconcile these differences by presenting a multidimensional measure of success, based on data collected from 118 expatriate respondents worldwide. A series of factor analyses, along with reliability and item analyses yielded nine measurement scales which included cultural adjustment, work-related adjustment, career development, HQ-subsidiary coordination, assignment completion, professional/skill development, shaping and controlling the subsidiary, satisfaction and overall assignment effectiveness. The process by which these scales were developed is described in the paper and all items and scale reliabilities are presented.     

Visual displays: analytical study and applications to graphs and real data

Principal axis methods such as principal component analysis (PCA) and correspondence analysis (CA) are useful for identifying structures in data through interesting planar graphic displays. However, some kinds of data sets can be dealt alternatively with PCA or CA. This paper focuses on methods, such as PCA and CA, and on visual displays. Our aim is to illustrate the implications for a potential user of selecting either method, and its advantages and disadvantages, from an applied point of view. This is a matter covered broadly in textbooks and elsewhere considering theoretical arguments. Our purpose is to contribute to the comparison between these methods, over the same data set, in order to illustrate them for the practitioner. In the first part of this paper we present a novel analytical study of a binary matrix associated with a non-oriented axis-symmetric graph and show that CA outperforms standardized PCA for the reconstitution and visualization of such kind of graphs. In the second part we present a case using real data dealing with the distribution of employees in different economic sectors for the countries of the European Union, analyzed by means of standardized PCA and two-way CA, in order to see the differences between the two methods in practice.     

Dynamic Costs of the Draft

Abstract. We propose a dynamic general‐equilibrium model with human capital accumulation to evaluate the economic consequences of compulsory services (such as military draft or social work). Our analysis identifies a so far ignored dynamic cost arising from distortions in time allocation over the life cycle. We provide conservative estimates for the excess burden that arises when the government relies on forced labor rather than on income taxation to finance public expenditures. Our results suggest that eliminating the draft could produce considerable dynamic gains, both in terms of GDP and lifetime utility.     

Enough is Enough: Cognitive Antecedents of Workaholism and Its Aftermath

Workaholism is commonly conceptualized as a compulsive inner drive to work excessively hard. This study investigates to what extent rigid personal beliefs—i.e., performance‐based self‐esteem (self‐esteem that is contingent upon good performance) and an enough continuation rule (continuing with work until one feels one has done enough)—contribute to exhaustion through workaholism. To examine these potential antecedents and consequences of workaholism, data of a two‐wave longitudinal survey study with a six‐month time interval was used (n = 191). Results of structural equation modeling provided support for our hypotheses. Taken together, our findings show that rigid personal beliefs at T1 predicted primarily working compulsively at T2, and working compulsively at T1 influenced exhaustion at T2. Moreover, reciprocal relationships were found between applying the enough continuation rule and working compulsively, and between working compulsively and exhaustion. These results suggest partial mediation from cognitive antecedents (personal beliefs) through workaholism to exhaustion. In practical terms, the results indicate that cognitive antecedents may provide a good starting point for interventions for preventing exhaustion and workaholism. © 2014 Wiley Periodicals, Inc.
