Abstract: | This paper reports the first attempt to measure the importance of controlling marine debris as an aesthetic characteristic of beaches and coastal area. The results are based on a contingent valuation survey designed to estimate the economic value people would place on controlling marine debris on recreational beaches in New Jersey and North Carolina. A Weibull survival model was estimated treating for and against votes as defining censoring points for an unknown willingness to pay distribution. The findings suggest: (1) people do distinguish situations with differing amounts of debris when they are described using color photographs; (2) the pilot survey implies measures of people's willingness to pay (WTP) for debris control are consistent with a scope test in that larger WTP is associated with programs intended to address situations for more serious background levels of debris; and (3) local beach conditions seem to influence how people interpreted the plans describing beach conditions without the proposed control programs. |
