由于巴勒斯坦之间长期的暴力冲突,以色列在巴勒斯坦领土上实施军事安全措施,对有关各方产生了负面经济影响。一个重要的结果是开展贸易的能力有限,从而带来福利损失。安全措施等冲突引发的政策可能会产生巨大的意想不到的外部性,从而影响粮食市场和贸易。我们评估以色列和西岸生产的食品的每日批发价格动态,这些食品在以色列和西岸之间进行交易,因此受到流动限制。为此,我们提出了一种机制切换协整模型,该模型使用 Johansen 估计方法的新颖扩展进行估计。我们发现,这两个地区的两大批发市场在这些主要贸易产品上是一体化的。价格均衡的偏差会迅速调整。该模型表明,流动限制暂时切断了市场之间的联系。冲突引发的福利关闭的影响取决于贸易的方向,并且正在损害巴勒斯坦和以色列的消费者。
Israel’s imposition of military security measures in the Palestinian territories as a consequence of the long-lasting violent conflict between them has negative economic effects on all parties concerned. One crucial outcome is the limited ability to carry out trade, which brings about welfare losses. Conflict-induced policies such as security measures can result in sizable unintended externalities that shape the markets of and the trade in food. We assess the dynamics of daily wholesale prices of food produced in Israel and the West Bank that is traded between them and is therefore subject to restrictions on movement. To do so, we suggest a regime switching cointegration model which is estimated using a novel extension of the Johansen estimation method. We find that the two major wholesale markets of the two regions are integrated with regard to these main trading products. Deviations from price equilibria are quickly adjusted. The model suggests that movement restrictions temporarily cut off markets from each other. Implications of conflict-induced closures for welfare depend on the direction of trade and are harming both Palestinian and Israeli consumers.
