摘要

在本文中，我们利用两次地理编码的横断面全国家庭调查和相应的道路地图，评估了1996年至2010年间道路发展对巴布亚新几内亚农村家庭福利的影响。我们利用巴布亚新几内亚国家道路资产管理系统中记录的路面类型和状况的时间变化，重点关注连接农村家庭和城市地区的路线。为了解决道路基础设施项目的内生布局问题，我们采用了一个相关的随机效应模型，该模型控制了分析期间特定地点的平均道路质量。我们还使用新开发的广义分位数回归方法来调查道路工程是否有利于穷人。我们的估计表明，通往最近城镇的更好的道路会提高消费水平和住房质量，并减少对自给农业的依赖。这种影响在贫困和偏远家庭中更为强烈。

The Impact of Road Development on Household Welfare in Rural Papua New Guinea

In this paper we evaluate the impact of road development on household welfare in rural Papua New Guinea (PNG) between 1996 and 2010, using two geocoded cross-sectional national household surveys and corresponding road maps. We make use of time-variation in road surface type and condition as recorded in PNG’s National Road Asset Management System, focusing on routes that connect rural households to urban areas. To tackle endogenous placement of road infrastructure programs, we employ a correlated random effects model that controls for the location-specific average road quality over the period of analysis. We also use a newly developed generalised quantile regression method to investigate whether road works favour the poor. Our estimates show that better roads to nearest towns lead to higher consumption levels and housing quality, and to less reliance on subsistence farming. The effects are stronger among poor and remote households.

期刊介绍： The Journal of Development Studies was the first and is one of the best known international journals in the area of development studies. Since its foundation in 1964, it has published many seminal articles on development and opened up new areas of debate. Priority is given to papers which are: • relevant to important current research in development policy, theory and analysis • make a novel and significant contribution to the field • provide critical tests, based on empirical work, of alternative theories, perspectives or schools of thought We invite articles that are interdisciplinary or focused on particular disciplines (e.g. economics, politics, geography, sociology or anthropology), with an expectation that all work is accessible to readers across the social sciences. The editors also welcome surveys of the literature in important fields of development policy. All research articles in this journal undergo rigorous peer review, based on initial editor screening and anonymous peer review. Given the high level of submissions, a majority of submissions are rejected quickly with reasons.
