Egypt plays a pivotal role in the security of the Middle East as the doorway to Europe and its military expenditure reflects its involvement in the machinations of such an unstable region, showing considerable variation over the last forty years. These characteristics make it a particularly...

We provide a simple proof of Foster's (1983) characterization of the Theil inequality index.

We develop univariate regime-switching GARCH (RS-GARCH) models wherein the conditional variance switches in time from one GARCH process to another. The switching is governed by a time-varying probability, specified as a function of past information. We provide sufficient conditions for geometric...

Conventional wisdom suggests that a global increase in monetary rewards should induce agents to exert higher effort. In this paper we demonstrate that this may not hold in team settings. In the context of sequential team production with positive externalities between agents, incentive reversal...

We show that current measures of welfare changes which are all based on the compensated variation (CV) and the equivalent variation (EV) do not apply to an economy with cities. In addition, since these measures are utilized in a partial equilibrium analysis they capture only part of the effect...

This paper examines the suitability of the proposed monetary union among the members of the Gulf Cooperation Council (GCC). To do so, we identify the underlying structural shocks that these economies are subject to and assess the extent to which the shocks are symmetric. Additionally, we test...

We study the optimal design of organizations under the assumption that agents in a contest care about their relative position. A judicious de?nition of status categories can be used by a principal in order to in?uence the agents?performance. We first consider a pure status case where there are...

Ben-David and Papell's (1997) tests for structural breaks in international trade ratios over the post-WWII period revealed that trade ratios exhibited structural breaks in their paths and that postbreak trade averages exceeded prebreak averages. They attributed these breaks to trade...

We show that temporally distancing the decision task from the payment of the reward increases honest behavior. Each of 427 Israeli soldiers fulfilling their mandatory military service rolled a six-sided die in private and reported the outcome to the unit's cadet coordinator. For every point...

This study proposes models that can be used as shorthand analysis tools for CDS spreads and CDS spread changes. For this purpose we examine the determinants of CDS spreads and spread changes on a broad database of 718 US firms during the period from early 2002 to early 2013. Contrary to previous...
