Productivity-Wage Gaps Among Age Groups: Does the ICT Environment Matter?

This paper disentangles the age-productivity-wage nexus by estimating productivity and wage equations with longitudinal employer-employee panel data for Belgium. Results indicate that workers above 49 years are significantly less productive than their younger colleagues. Moreover, while relative productivities across age groups are not found to differ significantly between ICT and non ICT firms, the upward sloping age-wage profile appears to be somewhat steeper in ICT firms. Yet, whatever the ICT environment, findings show that young workers are paid below and older workers above their marginal productivity. This pattern is in line with the deferred payment model developed by Lazear (J Polit Econ 87:1261–1284, 1979).     

EXPERIMENTAL EVIDENCE ON ENGLISH AUCTIONS: ORAL OUTCRY VERSUS CLOCK

This paper tests experimentally, in a common value setting, the equivalence between the Japanese English auction (or clock auction) and an oral outcry auction where bidders are allowed to call their own bids. We find that (i) bidding behaviour is different in each type of auction, but also that (ii) this difference in bidding behaviour does not affect significantly the auction prices. This lends some support to the equivalence between these two types of auction. The winner's curse is present: overbidding led to higher than expected prices (under Nash bidding strategies) in both types of auction. Although interesting and encouraging, the results clearly indicate that further research is necessary, particularly with a modified experimental design.     

The influence of empathy in complaint handling: Evidence of gratitudinal and transactional routes to loyalty

While most studies on complaint handling are focused on performance outcomes, analysis of the processes that reinforce relationship quality is lacking. Building on the relationship marketing theory of reciprocal behaviours, this research proposes and tests a model of the effects of empathy as a particular relationship recovery investment. Addressing for the first time the role of gratitude in a complaint-handling context, this model assumes that both gratitude and transactional satisfaction mediate the influence of empathy on consumers' trust and commitment. Data from a cross-industry survey of phone and online complaints confirmed the proposed model.     

Construct validity and second-order factorial model

Three second-order factorial models are defined, using the LISREL notation, to assess the univocity of a construct. The first model assumes that the constructs are heterogeneous, the second that they are homogeneous. The third model introduces the notion of partial homogeneity between constructs. Partial homogeneity is defined in terms of a LISREL second-order factor model. In some cases, this model offers a viable alternative to the collapsing of items into a unique scale. An example is given of scales which fit the partial homogeneity model.     

Investment and technological choice in a right-to-manage model

We analyze the interactions between investment and local wage bargaining in a putty-clay model where the investment decision commits the firm to a particular capital intensity. This technological precommitment is used strategically in order to manipulate the bargaining outcome. We show that this strategic behavior induces a nonmonotonic relationship between the capital and labor demands of the firm and most of its environmental parameters (e.g., the bargaining power of the union, its minimum wage requirement, the capital cost). The results we obtain in our putty-clay framework thus contradict several conclusions of the standard literature on wage bargaining and investment.     

Tariffs versus VAT in the presence of heterogeneous firms and an informal sector

The debate over the use of tariffs or value added taxes in developing countries has focused on the difficulty of collecting VAT from the informal sector. This paper contributes by considering this issue with heterogeneous firms and endogenous entry. This yields two results. First, a cut in the tariff reduces the size of the informal sector. Second, the imposition of VAT need not increase the size of the informal sector. Turning to simulation results, we find that switching from a tariff to a revenue-neutral VAT increases welfare, in part because of the selection effect generated by heterogeneous firms.     

Inter-Industry Wage Differentials: Evidence from Belgium in a Cross-National Perspective

This paper examines the existence and magnitude of inter-industry wage differentials in Belgium. Using the 1995 Structure of Earnings Survey, a rich employer-employee matched database, we find significant sectoral wage differentials among workers who are apparently similar from the point of view of their individual characteristics and working conditions. Results also suggest that these differences derive partly from the features of the employers in each sector (size of the establishment, bargaining regime). In an international perspective, results fit in with findings from earlier studies on the existence of a negative relation between the dispersion of inter-industry wage differentials and the degree of corporatism.     

Walloon & Flemish videotex trials

This article focuses on the problems surrounding ‘compunication’, ie the growing imbrication between electronic computers and telecommunications. (The corresponding French term is télématique). More precisely, the specific problems of videotex systems thrown up by different experiments in Belgium are examined. The CCITT of the ITU uses the term videotex as the generic name referring to all systems that make it possible to gain information through telecommunication networks (Hertzian waves, cable TV distribution networks or telephone lines). Requested information appears on a TV screen (at home, in a place of work or in a public place).
