The Niehans paradox,flexible exchange rates,and macroeconomic stability

This paper re-examines Dornbusch's suggestion that monetary expansion under a floating rate system will not cause a temporary decline in economic activity — the Niehans paradox — because households will cut their saving to maintain consumption spending on domestic goods. Despite this terms of trade effect on saving, it turns out that devaluation in the standard Keynesian model, in which trade flows, however, respond to the exchange rate with a simple distributed lag, produces a temporary decline in economic activity under certain plausible conditions. Consequently, the Niehans paradox still can arise if domestic expenditures respond sluggishly to lower interest rates.     

Fiscal Policy,Expectations, and Exchange-Rate Dynamics*

This paper uses the sticky-price monetary model to analyze the effects of fiscal policy on the exchange rate under alternative assumptions about exchange-rate expectations. the use of different expectations mechanisms-specifically the perfect-foresight model and the popular models tested by Frankel and Froot: regressive, adaptive, and distributed-lag-is based on recent empirical evidence suggesting that exchange-rate expectations may not be rational. the most surprising finding in the paper is that with adaptive and distributed-lag expectations, fiscal expansion has no initial impact on the exchange rate, and the same may be true for regressive expectations.     

On military RDT&E in Israel

Military research, development, testing and evaluation in Israel are described in historical perspective prior to the 1973 war. Emphasis is given to the advantages of short, informal lines of communication, flexibility in the process of weapons development and to the immediacy of perceived military threat as possible reasons for success of weapons developed by or weapons technologies adapted by Israel. Relatively small size of the nation and the military organization are also seen to be advantages for effective development or adoption of military technology.     

Research notes and communications management objectives in mergers and acquisitions

A taxonomy of managerial goals in mergers and acquisitions is developed through a cluster analysis of data from interviews with merger and acquisition practitioners. These clusters of objectives overlap with some objectives cited for mergers and acquisitions in the academic literature, but the correspondence is not complete. Further analysis shows that different types of mergers and acquisitions are characterized by different managerial objectives. The implications of this research for the development of a contingency model of the relationship between managerial objectives and mergers and acquisitions are discussed.
