From organizational values to mobilization of human resources

This study examines the relationship of perceived organizational values to employee mobilization behaviours as mediated by perceived organizational support (POS) and affective organizational commitment. Firstly, a scale comprising three types of perceived organizational values (interpersonal values, formal values, and individual well‐being‐centered values) was developed and validated using a sample of 580 employees. Secondly, the relationships among variables were examined using structural equations modeling on an independent sample of 260 employees. POS mediated the relationship between employees' perceptions that their organization values the individual well‐being of its members and their affective organizational commitment, which in turn mediated the relationship between POS and individual mobilization behaviours. The contributions of these findings to advancing scholarship and practice are discussed. Copyright © 2010 ASAC. Published by John Wiley & Sons, Ltd.     

The statistical properties of the innovations in multivariate ARCH processes in high dimensions

The long memory linear ARCH process is extended to a multivariate universe, where the natural cross-product structure of the covariance is generalized by adding two bi-linear terms with their respective parameter. The residuals of the linear ARCH process are computed using historical data and the (inverse square root of the) covariance matrix. Simple measures of quality assessing the independence and unit magnitude of the residual distributions are proposed. The salient statistical properties of the computed residuals are studied for three data sets of size 54, 55 and 330. Both new terms introduced in the covariance help to produce uncorrelated residuals, but the mean residual magnitudes are much larger than one. The large magnitudes of the residuals are due to the exponential decay of the covariance eigenvalues, corresponding to directions with very small fluctuations in the historical sample. Because the postulated properties of the innovations cannot be obtained regardless of the parameter values, subsequent inferences reach a fundamental limitation in a large multivariate universe.     

Making sense of Bolkestein-bashing: Trade liberalization under segmented labor markets

An increase in the range of tradable goods is analyzed in a two-country Dornbusch-Fischer-Samuelson style model, where labor cannot relocate to another sector upon a non-expected increase in the range of goods that can be traded.The effect of liberalization on the terms of trade tend to favor the poorer country (the “East”), if (as assumed) the most sophisticated goods are tradable before reform. Second, under ex-post liberalization, there exists a class of workers in the West who are harmed because they face competition from Eastern workers and cannot relocate to other activities. But if the East's economy is relatively small, their wage losses are not very large. Things are different, however, if there exist asymmetries in labor market institutions, such that upon reform, labor can relocate in the East but not in the West. Some workers in the West can then experience very large wage losses. Thus, rigid labor markets in the West magnify opposition to reform there.     

The relationship between career plateauing,employee commitment and psychological distress: the role of organizational and supervisor support

This research examines the role played by an employee's supervisor and organization in the relationship between structural and content plateauing, affective commitment to the organization, and psychological distress. Our analyses, based on data taken from a sample of 575 hospital employees, reveal that there is a significant relationship between the two forms of plateauing and perceived supervisor support, whereas only hierarchical plateauing is related to perceived organizational support. Our results also highlight the mediating effect of perceived organizational support in the relationship between hierarchical plateauing, perceived supervisor support, and the consequences examined.     

Intergenerational Wealth Mobility in France, 19th and 20th Century

This paper examines intergenerational wealth mobility between fathers and children in France between 1848 and 1960. Considering wealth mobility in the long run requires taking into account not only positional mobility (that is, how families move within a given distribution of wealth), but also structural mobility induced by changes in the distribution of wealth. Such changes are related to two structural phenomena: in the nineteenth century, the rising number of individuals leaving no estate at death and, after World War I, the decline in the number of the very rich who could live off their wealth. The paper studies the movements between these groups and estimates the intergenerational elasticity of wealth, taking into account the persistence at the bottom and at the top.     

An integrated production planning model for molds and end items

This study develops a mathematical modelling framework for simultaneously generating production plans for molds and the end items that are made with them. The inputs considered are the item demand (assumed constant over an infinite planning horizon), holding costs and shortage costs, together with the molds’ statistical lifetime distribution (in terms of number of uses) and costs pertaining to amortization, preventive replacements and corrective replacements.
