摘要

在敌对行动结束后很长一段时间,地雷仍影响着许多冲突地区数百万人的生活。然而,关于排雷作用的研究很少。我们研究了莫桑比克清除地雷的经济后果,莫桑比克是唯一一个从1992年的严重污染过渡到2015年无地雷的国家。首先,我们提出了自组装的疑似污染地区的地理参考目录,以及排雷行动的详细记录。其次,事件研究分析揭示了排雷活动与随后的当地经济表现之间的密切联系,这反映在亮度上。在清理之前的几年里,经济活动并没有好转,当运营商调查之前被错误标记为污染的地区时,经济活动也没有增加。第三,认识到清除地雷会改变交通运输,我们采用市场准入方法来探讨直接和间接影响。为了进一步确定,我们将在以前被认为安全的地区清除地雷所造成的市场准入变化与早期的全国性调查隔离开来。第四,政策模拟揭示了清盘给整个经济带来的巨大红利,但前提是考虑到市场准入效应,后者使直接的生产率联系相形见绌。此外,政策反事实表明,当排雷没有优先考虑运输路线的畅通时,会产生巨大的总成本。这些结果为乌克兰和其他地区排雷计划的设计提供了见解,突出了集中协调和优先考虑促进商业的领域的必要性。

Landmines and Spatial Development

Landmines and Spatial Development

Landmines affect the lives of millions in many conflict-ridden communities long after the end of hostilities. However, there is little research on the role of demining. We examine the economic consequences of landmine removal in Mozambique, the only country to transition from heavily contaminated in 1992 to mine-free in 2015. First, we present the self-assembled georeferenced catalog of areas suspected of contamination, along with a detailed record of demining operations. Second, the event-study analysis reveals a robust association between demining activities and subsequent local economic performance, reflected in luminosity. Economic activity does not pick up in the years leading up to clearance, nor does it increase when operators investigate areas mistakenly marked as contaminated in prior surveys. Third, recognizing that landmine removal reshapes transportation access, we use a market-access approach to explore direct and indirect effects. To advance on identification, we isolate changes in market access caused by removing landmines in previously considered safe areas, far from earlier nationwide surveys. Fourth, policy simulations reveal the substantial economywide dividends of clearance, but only when factoring in market-access effects, which dwarf direct productivity links. Additionally, policy counterfactuals uncover significant aggregate costs when demining does not prioritize the unblocking of transportation routes. These results offer insights into the design of demining programs in Ukraine and elsewhere, highlighting the need for centralized coordination and prioritization of areas facilitating commerce.

期刊介绍: Econometrica publishes original articles in all branches of economics - theoretical and empirical, abstract and applied, providing wide-ranging coverage across the subject area. It promotes studies that aim at the unification of the theoretical-quantitative and the empirical-quantitative approach to economic problems and that are penetrated by constructive and rigorous thinking. It explores a unique range of topics each year - from the frontier of theoretical developments in many new and important areas, to research on current and applied economic problems, to methodologically innovative, theoretical and applied studies in econometrics. Econometrica maintains a long tradition that submitted articles are refereed carefully and that detailed and thoughtful referee reports are provided to the author as an aid to scientific research, thus ensuring the high calibre of papers found in Econometrica. An international board of editors, together with the referees it has selected, has succeeded in substantially reducing editorial turnaround time, thereby encouraging submissions of the highest quality. We strongly encourage recent Ph. D. graduates to submit their work to Econometrica. Our policy is to take into account the fact that recent graduates are less experienced in the process of writing and submitting papers.
