Evaluating the Public Value of Improving Early Detection Accuracy of Cumulonimbus Using a Geostationary Satellite in South Korea
The Cheollian Satellite 2A called Geo-Kompsat-2A is a geostationary meteorological satellite operated by Korea Meteorological Administration for weather and space-weather observation purposes. This article seeks to evaluate the public value arising from improving the accuracy of early detection of cumulonimbus using Geo-Kompsat-2A. To this end, an economic technique called contingent valuation (CV) is adopted taking a three step approach. In step 1, a CV questionnaire was prepared for deriving the willingness to pay (WTP) for the improvement. In step 2, a nationwide survey of 1000 households was conducted using the CV questionnaire and employing person-to-person interviews with household visits. In step 3, the average WTP was estimated. The yearly household average WTP was KRW 2143 (USD 1.91), securing statistical significance. Adjusting this value to suit the entire population of South Korea produces a yearly public value of KRW 44.1 billion (USD 39.3 million). Although it is not easy to accurately evaluate the costs involved in the improvement, the results of conducting a pilot cost-benefit analysis suggest that the improvement secures social desirability.
期刊介绍:
Space Policy is an international, interdisciplinary journal which draws on the fields of international relations, economics, history, aerospace studies, security studies, development studies, political science and ethics to provide discussion and analysis of space activities in their political, economic, industrial, legal, cultural and social contexts. Alongside full-length papers, which are subject to a double-blind peer review system, the journal publishes opinion pieces, case studies and short reports and, in so doing, it aims to provide a forum for the exchange of ideas and opinions and a means by which authors can alert policy makers and international organizations to their views. Space Policy is also a journal of record, reproducing, in whole or part, official documents such as treaties, space agency plans or government reports relevant to the space community. Views expressed in the journal are not necessarily those of the editors or members of the editorial board.
