Private irrigation investment in Colombia: effects of violence, macroeconomic policy, and environmental conditions
识别并估计了暴力、气候和政府价格信贷政策对哥伦比亚各地区私人灌溉投资的影响，发现暴力有负面作用，气候适宜地区投资吸引力较低，而政府政策能促进投资。
Abstract This paper identifies and estimates the effects of several determinant, on private investment in irrigation in Colombia. It attempts to quantify macroeconomic policy, environment, and violence variables that have been identified in previous studies as significantly affecting investment, in agriculture in genera., and in irrigation in particular. Variables such as violence, climate, and governmental price credit policies are used to explain changes in private investment in irrigation across regions and over time. Violence negatively affects private investment. Climate affects the investment such that in regions with favorable climate condition, investment in irrigation is less attractive, and appropriate government crop‐price and credit policies promote investment in irrigation.
