Managerial expertise,learning potential and dynamic incentives: get more for less?

In this paper the impact of ability and learning potential on incentive contracts is analyzed. A central feature of the model is that the true ability will not be revealed. The learning potential of an agent is modeled as the magnitude of impact on the agent's expected ability that learning‐by‐doing has in a given task. Absent a managerial labor market, depending on an agent's learning potential, a monotone or non‐monotone pay structure may be optimal. The second important result is that using agents' ability distributions as inputs to information systems, higher learning potentials lead to less costly information systems, i.e. actions can be implemented at lower costs. Additionally, it is proven that the criteria cost minimization and value maximization are equivalent in the model's context. Copyright © 2007 John Wiley & Sons, Ltd.     

Accountability in an agency model: Project selection,effort incentives,and contract design*

We analyze an agency model of project choice and implementation where the agent is held accountable for his performance. We show that implementation of the ex ante efficient project may be impossible, irrespective of how the principal sets fixed wage and bonus rate. If it is possible, the principal may be forced to increase the bonus rate above the optimal project‐specific rate. The higher profit share compensates the agent for pressure he faces when he has to justify/explain his performance.     

Urban Informality and the State: Geographical Translations and Conceptual Alliances

Understandings of informality commonly derive from research undertaken in states perceived as lacking the capacity to regulate the practices of their populations. This Interventions forum aims to expand the geographical parameters of empirical research on urban informality. A more global approach, we argue, also necessitates questioning assumptions that undergird this concept—in particular the underlying conception of the state. In this vein, this collection of papers aims to rethink theories of the state through the lens of informality, and vice versa, to inform and refine the concept of informality through a more thorough understanding of states. In so doing, the contributions engage with concepts that have been central both to theories of the state and to the study of informality, namely governance, agency, legitimacy, sovereignty and legality. Following this introduction setting out our theoretical approach, the Interventions forum unites five empirical studies that discuss the nexus of informality and states in contexts that have been researched less extensively from this perspective, each tackling one of the above‐mentioned concepts. Based on these different entry points, the papers provide novel angles on a state‐theoretical understanding of informality. A concluding essay brings these approaches together, reflecting on the possibilities of translating concepts to different sites.     

家族企业要行使好所有权

那些能够延续三代或三代以上的家族企业,往往比其他同类企业更具竞争力。＂家族＂的两个难题家族企业往往是一种被忽略的所有制形式。然而,家族企业无所不在：从社区周围的夫妻店,到数百万支撑众多经济体的中小型企业,再到宝马、三星和沃尔玛等家喻户晓的巨头,到处都能见到家族企业的身影。     

Trade union cross‐border alliances within MNCs: disentangling union dynamics at the local,national and international levels

This study identifies three types of workplace union strategy in the development of cross‐border relations within North American and European multinational companies: defensive isolation, risk reduction and proactive solidarity. Qualitative case studies of MNCs with operations in Canada and Mexico indicate that the nature and intensity of participation in cross‐border trade union alliances are shaped by the union dynamic at the local, national and international levels. A combination of greater workplace union power resources, notably discursive capacity, and of strong supportive approach of the national union, notably dedicated resources and space for bottom‐up initiatives, contributes to proactive solidarity strategies towards international union networks. The absence of these factors is associated with risk reduction and defensive isolation strategies.     

Education and early career outcomes of second-generation immigrants in France

We estimate a flexible reduced form dynamic model of schooling choices and labor market outcomes in France. Our analysis focuses on the comparison between second-generation immigrants and their French-natives counterparts. We show that the gap in higher education attainments between those two sub-populations is mainly explained by parents' background, and that schooling investment is the main determinant of the gap in permanent employment. After conditioning on schooling and observed characteristics, we find that ethnic origin explains less than 6% of the gap in access to permanent employment. A test of equality of counterfactual probabilities of accessing permanent employment across ethnic groups (measured at identical individual characteristics) typically fails to be rejected.     

Envy-minimizing unemployment benefits

This paper offers an analysis of the optimality of unemployment benefits based on the concept of no-envy. Using a general equilibrium framework with uncertainty, we derive the conditions for a trade-off between the intensity of envy and the expected percentage of envious persons. If the government's sensitivity to the intensity of envy is not too strong (alongside conditions on households' utilities), the optimal benefit is positive and below the full-insurance level. We also show that, for a low enough sensitivity to the intensity of envy, the optimal replacement ratio decreases with unfavorable changes in the distribution of the technological shock.     

Base stock policies with degraded service to larger orders

We study an inventory system controlled by a base stock policy assuming a compound renewal demand process. We extend the base stock policy by incorporating rules for degrading the service of larger orders. Two specific rules are considered, denoted as Postpone(q,t) and Split(q), respectively. The parameter q distinguishes between regular orders (of size less than or equal to q) and larger orders. We develop mathematical expressions for the performance measures: order fill rate of the regular orders and average on-hand inventory level. We make numerical experiments where the postpone parameter t and the base stock levels of each rule are such that all customers (of both order types) are indifferent between the two rules. When comparing the difference in the average on-hand inventory levels, we can then make an assessment of the threshold value of the cost of splitting an order (which may otherwise be hard to quantify) in the rule Split(q). Our numerical results indicate that this threshold value is increasing in the variance of the order sizes. Based on the numerical experiment our conclusion is therefore that when the variance of the order sizes is low, then Postpone(q,t) seems to be a good option, while when the variance is high, then Split(q) is more competitive.     

Feel free to feel comfortable—An empirical analysis of ergonomics in the German automotive industry

The purpose of this paper is to examine ways to improve ergonomics on the manufacturing shop floor. In particular, the impact of certain ergonomic practices on companies' economic and social objectives is investigated empirically. In order to do so, a survey has been conducted among manufacturing managers of 55 companies in the German automotive industry. The managers have been asked about their estimations on harmful tasks within the production process and on the effectiveness of various practices in the context of ergonomics and health. Worker-oriented and work-oriented practices of ergonomics are operationalized using factor analysis. By means of a cluster analysis, companies with a high degree of implementation of ergonomic practices are identified. The analysis shows that plants with a higher implementation degree of ergonomic practices show a better performance in terms of economic and social objectives. Furthermore, the results reveal that work-oriented practices lead to better performance with respect to the investigated economic and social objectives, whereas worker-oriented practices play a supporting role only. Finally recommendations for manufacturing companies with regard to the field of ergonomics are derived from the empirical results.
