The article presents a study on the impact of fuel shortages on unemployment and product in Israel. The ministries of Finance and Labour were interested in knowing the influence that a possible shortage of fuel oil would have on employment and production levels in the Israeli Economy. A Linear Programming model that maximizes Total Final Uses was designed. The most time consuming part of the research was to obtain the distribution of the fuels for the different branches. For this purpose tens of thousands of consumers listed on the fuel suppliers' sales records had to be classified according to the Israel Industrial Classification and then retranslated to the same 83 branches. Several bodies participated in the data collection, the Central Bureau of Statistics, The Central Bank of Israel, The Electric Corp. and the Ministry of Finance. The model, including 166 variables and 250 constraints, was run on a CDC 6400, using the APEX II package. Initial runs were carried out for the 1975 level of activity of the Israel economy and the results verified the model.

This article presents an update related to management science as of November 1, 1973. Decision Sciences Corp. (DSC) has recently completed the development of an assessment methodology for fiscal impact of proposed new land development on local government in the State of New Jersey. DSC had been commissioned by the Division of State and Regional Planning in the Department of Community Affairs to carry out a preliminary investigation into problems and opportunities for providing assistance to local municipalities for evaluating this fiscal and economic impact. The computational methodology, called the Community Development Evaluation Program, was formulated to provide for quick, easy evaluation of major economic and fiscal impact at the local level and to analyze the viability of new residential/commercial projects throughout the State. Israel's water economy will most likely encounter a growing gap between its potential supply from natural resources and the level of water consumption. The problem of balance between water supply and demand will be a subject of major interest to policy makers in the seventies with two alternatives to be decided upon: first, freezing of water consumption at the current level and second, expansion of water consumption, along with a growth of potential supply by the development of new non-conventional and costly water resources.
