Understanding the Processes Underlying Inter‐firm Collaboration: Mutual Forbearance and the Principle of Congruity

This paper makes a theoretical innovation by integrating two key principles – mutual forbearance and the principle of congruity – into one general process model. It examines the micro‐mechanisms underlying the formation of a mutual‐forbearance agreement and explicates the role of time and of individual actions. We further understanding of the process of cooperation building by drawing a parallel between early stages of the formation process of mutual forbearance and cooperation, and argue that mutual forbearance may, under certain conditions, lead to long‐term cooperation or, if mismanaged, completely smother any chances of it. A prospective agreement may be put at risk when potential contributions are evaluated differently by each party and no action to mitigate the consequences is taken; even more so in a mutual‐forbearance context when the parties can only observe their counterparts’ actions through the market. Our model takes into account the micro‐mechanisms associated with the time between the actions of one entity/individual (e.g. the top manager) and the reaction of another entity/individual, the boundary conditions of the background to those actions and the alternative actions available during this time. Propositions for further exploration and implications are drawn.     

Egg and seed removal at urban and suburban forest edges

Predation rates of natural and artificial bird nests in rural landscapes have been the subject of numerous studies, often in the context of proximity to edge. Similar studies in urban and suburban landscapes are lacking. We carried out a study of egg and seed removal at forest reserve edges in three urban and two suburban forests in and near New York City in 1994-1995. Few significant edge effects were found, but this may have been because of the extraordinarily high rates of egg and seed removal. Daily removal rates were higher in suburban sites (eggs, 86%; seeds, 95%) than in urban sites (eggs, 64%; seeds, 88%). Exposed seeds and eggs suffered higher rates of removal than seeds and eggs covered by leaf litter. Despite statistically significant differences among treatments, all of these rates would be prohibitively high if experienced by ground-nesting birds or large-seeded trees (if removal was associated with predation). A survey of the literature suggests that egg predation rates are prohibitively high in cities and peak in suburban sites (at least in this study), then drop rapidly in ex-urban and rural sites, perhaps because of a similar pattern in the abundance of corvid bird predators. This revised version was published online in July 2006 with corrections to the Cover Date.

Job Tenure,Labour Mobility and Wage Profiles

Abstract. The features and the length of the attachment of workers to firms represent a central aspect of the labour relationship. The length of service is an important determinant of wages and of non-pecuniary benefits; it affects internal mobility in the firm, and insulates workers with long job tenure from unemployment. In this paper it is argued that the traditional “spot” labour market Characterization is difficult to reconcile with the existence of long term employment relationships. A number of alternative theories which predict the existence of an employer-worker attachment proposed, and their implications discussed. The relevance of long term employment relationships is then tested using micro-data for the Italian manufacturing industry. An appropriate methodology for the analysis of the duration of employment is developed. and separate “job tenure” equations for white and blue collar workers are estimated. A higher educational attainment - ceteris paribus- appears to increase the probability of a job separation; conversely, a higher working experience, previous to the current job, tends to reduce it. The effect of firm size is negative, as larger organizations seem to favour longer employment spells. Outside opportunities show a strong positive effect on the probability of separation. Finally, conditional on the current wage, the probability of leaving the job increases with the length of time worked. However, when the unconditional outcome is considered, separation decline with tenure; in this case. it is argued, the wage effect more than outweighs the conditional effect. This result is consistent with the predictions of both “specific” human capital and job matching theories.
