Advance Notification of Plant Closing: Does It Matter?

A review of the literature on the empirical effects of advance notification of plant closings (voluntary and mandated), including the authors' recent study using data drawn from the 1984 Survey of Displaced Workers. suggests that advance notice reduces the probalility that displaced workers suffer any spells of unemployment and may also moderated temporary increases in area unemployment rates. There is little evidence of adverse effects of advance notice, either to workers or to firms. The implications for public policy are discussed.     

Job Security Provisions and Employment: Revised Estimates

This article provides estimates of the effect of statutory severance pay and notice on four labor market outcome indicators, closely following Lazear (1990) but correcting for errors in his dependent variables and covariates. Although we corroborate the directional influence of severance pay for three of the indicators, there is little to suggest that its contribution to rising unemployment is material. Also contrary to Lazear, longer notice appears to be associated with broadly favorable outcomes.     

Employment Protection Reform,Enforcement in Collective Agreements and Worker Flows

We analyze a reform of notice periods for employer‐initiated separations in Sweden, which reduced the notice periods for newly hired older workers substantially but implied minor or no changes in the advance notices for younger workers. The reform was initiated at different times depending on collective agreement. These circumstances provide ample opportunity for the identification of its effects. Our findings indicate heterogeneous effects on hirings and separations across collective agreements.

Advance Notice and Job Search: More on the Value of an Early Start

This paper investigates the effects of advance notice of impending job loss on the length of jobless spells of displaced workers. We evaluate the performance of a formal search model and offer a generalization of the model that provides an alternative but related approach to the most recent empirically based literature. Evidence of gains from early search are found for all broad gender-occupation groups except blue-collar males.

More theory,in theory

An important aspect of the milk and dairy industry in the European Community is the reaction of milk producers to milk prices. In theory farmers behave like the economic man of basic economic textbooks. In practice, farmers behave quite differently, ie they increase their production when prices fall. For policy makers in the field of dairy products it is essential to know the reaction of the farming industry. Surprisingly this information is not available in the EEC; there are various opinions and estimates but they are heavily disputed. However, we now have the results of a study which can settle the dispute.¹ It is interesting to see the results and to notice that there really is a fundamental problem involved, ie how to discriminate between economic models.

Termination notice of mobile network operator customers after a tariff switch: An empirical study of postpaid subscribers in Germany

Proactive subscriber churn management strategies of mobile network operators (MNOs) require that steps are taken to keep customers before they hand over a formal notice of termination to their provider. Therefore, several studies have analyzed how MNO customers who gave a termination announcement differ from individuals who did not communicate this message. However, no work has examined such differences among subscribers who recently switched to another tariff of their MNO. Therefore, this paper explores socio-demographic, service consumption and tariff change differences between contract cancellation “announcers” and “non-announcers” in a sample of 1810 postpaid customers who had changed their rate plan not long ago. Cancellation announcers were more likely to be males who decreased their mobile voice consumption after their tariff switch, had already attempted to churn in the past, had moved from an unmetered to a metered rate type, paid higher monthly bill amounts and received no discounts on their current rate plan that was introduced on the market some time ago. Among subscribers who gave a termination notice, early (late) cancellation announcers were more likely to be older (younger) customers with a growing (shrinking) SMS consumption after their tariff switch, had not attempted (had already tried) to leave their current MNO in the past, and were in a rate plan that was (not) recently introduced. The findings contribute to the literature on mobile customer retention and have implications for practitioners and scholars.     

Buyer (dis)satisfaction and process innovation: The case of information technology services provision

Studying buyer satisfaction within business services is important because if buyer expectations are not addressed, it can endanger the relationship. Dissatisfied buyers can remain silent or switch supplier without notice, damaging the supplier-buyer relationship. Therefore, suppliers often invest substantial effort in collecting feedback with an expectation that it will foster improvements and innovation in processes. However, using a mixed method sequential research design, we find that there is no direct association between the level of dissatisfaction and process innovation: this poses questions about redundancy of feedback collection. We find that there is a time lag between dissatisfaction identification and problem resolution. We also find that there is a cognitive gap between a supplier's interpretation of the buyer's expectations and the buyer's actual expectations. Further, existing processes that are improved repetitively using discontent feedback suffer from diminishing returns. Suppliers need to proactively seek solutions rather than reactively dealing with buyer problems.

The influence of prior industry affiliation on framing in nascent industries: the evolution of digital cameras

New industries sparked by technological change are characterized by high uncertainty. In this paper, we explore how a firm's conceptualization of products in this context, as reflected by product feature choices, is influenced by prior industry affiliation. We study digital cameras introduced from 1991–2006 by firms from three prior industries. We hypothesize and find that: (1) prior industry experience shapes a set of shared beliefs that results in similar and concurrent firm behavior; (2) firms notice and imitate the behaviors of firms from the same prior industry; and, (3) as firms gain experience with particular features, the influence of prior industry decreases. This study extends previous research on firm entry into new domains by examining heterogeneity in firms' framing and feature‐level entry choices. Copyright © 2011 John Wiley & Sons, Ltd.     

Effects of downsizing practices on the performance of hospitals

Research has found that downsizing is not generally followed by improved organizational performance. Using a sample of hospitals that recently downsized, we evaluate the effects on performance of the human resource management (HRM) practices used in layoffs. Strategic HRM theory suggests that practices can have an impact on performance outcomes. We find that showing consideration for employees' morale and welfare during downsizing is positively related both to perceived success of downsizing and to financial performance following layoffs. Advance notice of layoffs is positively related to subsequent financial performance, but the provision of extended insurance to laid‐off employees is negatively related to financial performance. Planned redesign of work structures is positively related to perceived success, but has neutral to negative effects on financial performance. Copyright © 2004 John Wiley & Sons, Ltd.

Help with solving technological problems in project activities

In France, project activities figure predominantly in technology education. The general idea behind learning based on project activity is to allow the pupil to get involved in the activity in question, with the pupil tackling real situations rather than ones of an abstract nature. But too often, we notice that the pedagogical strategies used by teachers in project activities are not particularly effective from a learning point of view. What must be done in order to render project work in technology teaching genuinely effective? In this article, we make the following suggestion: if specific help, based on the pupil’s level of understanding of the activity relating to technologically based problem solving in project work, is made available by the teacher, then project activity can become much more effective from a learning point of view. By using situations highlighting project activities in the technology teaching domain, we analyse the knowledge used by pupils. We then present the specific help used by the teacher as well as the resulting effects upon student activity. We highlight the fact that if specific help conceived as a result of analysing student activity is put in place, the pupil learns more effectually.

Inflation,Taxes, and the Demand For Housing*

Inflation affects homeownership and housing adversely through the “real-payment tilt” of the conventional mortgage. Expectations of additional housing price appreciation, however, may induce households to invest in housing. This paper uses household data to estimate the demand for homeownership and housing, and it takes explicit notice of expectations of housing price appreciation. The results indicate for each 1% increase in the inflation rate that the conditional probability of purchase falls by 3%. Interest rate effects outweigh appreciation and tax effects. Given the decision to purchase, housing appreciation expectations do not have large effects on the amount purchased.
