The Effect of Educational Background On Performance and Organisational Commitment

In this research note Gedaliahu Harel, Senior Lecturer in Human Resource Management at the Israel Institute of Technology, and Yehuda Baruch, Visiting Fellow at the City University Business School, explore the effects of a special educational and training programme that affects the backgrounds of employees in technical jobs measured by variables such as level of performance, professionalism, and organisational commitment. the results are considered in terms of the particular population examined and the implications discussed for the use of special vocational education and training.     

Rules versus discretion - A disinflation case

This paper compares a strict inflation target regime to a conservative central bank regime to determine the monetary regime appropriate for a disinflation process. The analysis shows that in a two-period model, in which policymakers face given first-period inflationary expectations, a strict inflation target could be preferred to the appointment of a conservative central banker who has discretion. The result differs from that of Rogoff (1985), who assumed rational expectations and concluded that a conservative central banker is always preferable. The disadvantage of the conservative central banker derives from his tendency to accelerate disinflation relative to rate that maximizes social welfare.JEL Classification: E52, E58The authors are grateful to Alex Cukierman, Nissan Liviatan, Allan Drazen, Amit Friedman and Yoav Friedmann for their useful suggestions.

Endogenous private information structures

We formally incorporate the option to gather information into a game and thus endogenize the information structure. We ask whether models with exogenous information structures are robust with respect to this endogenization. Any Nash equilibrium of the game with information acquisition induces a Nash equilibrium in the corresponding game with an exogenous structure. We provide sufficient conditions on the structure of the game for which this remains true when ‘Nash’ is replaced by ‘sequential’. We characterize the (sequential) Nash equilibria of games with exogenous information structures that can arise as a (sequential) Nash equilibrium of games with endogenous information acquisition.     

Expatriation and repatriation in MNCs: a taxonomy

The challenge of the management of expatriates and repatriates has never been more timely nor urgent: globalization has forced expatriation into the corporate agenda, confronting us with an array of questions on HRM strategy and practice. We propose that a wide range of current thinking and practice may be conveniently grouped into a taxonomy of five organizational options, each advancing a different set of expatriation relationships: Global, Emissary, Peripheral, Professional, and Expedient. A framework outlining the main configurations of these options generates a generic model for expatriation at the organizational level. This forms the principal part of the article, followed by a comprehensive discussion and implications for practice. © 2002 Wiley Periodicals, Inc.     

An agency theory perspective of the Israeli labor market segmentation: Past,present, and future

In this paper we use agency theory to present a process of the dichotomization of the Israeli workforce into two structures, each representing distinct organizational cultures. The first structure is the private sector, led by the high-tech industry; a model where the principal has strong control over the activities of the agent. The second is the public sector, an opposing model in which the principal has virtually no control over the activities of the agents and as a result, the effectiveness within this sector deteriorates. We argue that such conflicting systems cannot exist side by side without affecting each other and we suggest a role for human resource management (HRM) in future developments. Within the public sector it is the responsibility of the principal, the Israeli government, to gain more control over the agent and employ professional HRM systems for this purpose.     

Reinsurers' investment and underwriting portfolios and the exchange rates risk

Summary and concluding remarks The traditional analysis of the performance of large international reinsurers typically concentrates on the effect of exchange rates on profitability of the firm (NRG [9]). The multi-index model enables us to capture and analyze two additional effects: According to the Interest Rates Parity Theorem, the expected rates of return on foreign investments already reflect the expected change in the exchange rate. Therefore, a firm operating in a perfect market would be indifferent to the currency denomination of its financial assets. The firm should consider only the unexpected element in the exchange rate movements, i.e., the exchange risk. The uncertainty in the exchange rate contributes to the variability of the return on each investment and underwriting project. The firm must consider this new element of risk while constructing its investment and insurance portfolios. p ]The model can be used to examine and analyze alternative policies of the firm operating in international markets. For example, the model can be used to examine the “full hedge” policy, in which the insurer has a zero net position in any non-reference currency, or the policy of isolating national insurance markets.     

Strong price of anarchy

A strong equilibrium is a pure Nash equilibrium which is resilient to deviations by coalitions. We define the strong price of anarchy (SPoA) to be the ratio of the worst strong equilibrium to the social optimum. Differently from the Price of Anarchy (defined as the ratio of the worst Nash Equilibrium to the social optimum), it quantifies the loss incurred from the lack of a central designer in settings that allow for coordination.We study the SPoA in two settings, namely job scheduling and network creation. In the job scheduling game we show that for unrelated machines the SPoA can be bounded as a function of the number of machines and the size of the coalition. For the network creation game we show that the SPoA is at most 2. In both cases we show that a strong equilibrium always exists, except for a well defined subset of network creation games.     

No such thing as a global manager

With the continuing growth of globalization, companies need to pay careful attention to selecting and managing people who may become their “global managers.” The best way to achieve this is by coming up with a clear concept of what constitutes such a manager. But the examination of a wide set of possible characteristics indicates that there seems to be no distinct set of such individual qualities, so there is no consistent way to point out what a global manager is. What we are left with is the search for good “conventional” managers with a global mindset who could succeed in the international marketplace.
