Planning reforms have been advanced under the premise that streamlining planning will expedite development and growth, arguing that regulatory planning is a binding constraint on development. Yet, the veracity of this premise has not been substantiated empirically. In this study we analyze the effects of two reforms that were advanced under this premise in Israel during the last decade: a supra-commission that can bypass all others to approve large-scale housing plans and a strategic housing plan (SHP) that stipulates how many residential units should be approved each year in different parts of the country until 2040. We find that the planning of residences has indeed been expedited, and the SHP planning goals were exceeded. Yet, housing starts did not go up and thus the reforms had no appreciable effect on housing prices. Thus, we find that the premise underlying these reforms does not stand up to scrutiny. Concurrently the resulting excessive planning has adverse effects on agriculture and open spaces. Moreover, the resulting plans are likely to remain unbuilt for a long period of time, resulting in them being dated by the time they may be built. The SHP has reverted the Israeli planning system to silo planning undermining the comprehensive planning doctrine advanced since the 1990s. Thus, while the reforms do not seem to advance their purported benefits they do generate long-term negative externalities.

在简化计划将加快发展和增长的前提下，推进了计划改革，认为监管计划对发展具有约束力。但是，该前提的准确性尚未从经验上得到证实。在这项研究中，我们分析了在过去十年中在此前提下在以色列进行的两项改革的效果：超委员会可以绕过所有其他人来批准大规模住房计划；战略住房计划（SHP）规定了如何到2040年，每年在该国的不同地区都应该批准许多住宅单元。我们发现确实加快了住宅的规划，并且超出了SHP的规划目标。然而，住房开工没有增加，因此，改革对房价没有明显影响。从而，我们发现，这些改革所基于的前提无法经受审查。同时，由此产生的过度规划会对农业和开放空间产生不利影响。此外，生成的计划很可能会长时间保持未构建状态，从而导致它们在构建时就已过时。SHP已将以色列的计划系统恢复为筒仓计划，从而破坏了自1990年代以来提出的全面计划理论。因此，尽管改革似乎并未提高其所谓的利益，但确实会产生长期的负面外部性。导致它们在制造时已过时。SHP已将以色列的计划系统恢复为筒仓计划，从而破坏了自1990年代以来提出的全面计划理论。因此，尽管改革似乎并未提高其所谓的利益，但确实会产生长期的负面外部性。导致它们在制造时已过时。SHP已将以色列的计划系统恢复为筒仓计划，从而破坏了自1990年代以来提出的全面计划理论。因此，尽管改革似乎并未提高其所谓的利益，但确实会产生长期的负面外部性。
