Serkan Catma is an Associate Professor of Economics at the University of South Carolina Beaufort. He received his Ph.D. and MBA from West Virginia University and has over 13 years of experience in academia. Dr. Catma has conducted three different types of research: (a) academic - where he contributed to the literature by publishing papers in refereed journals; (b) institutional – where he conducted research specifically at the request of the university administration, and (c) policy analysis – where he produced research reports/papers that focused on public policy analysis. His current research agenda includes three main areas: Environmental Economics, Economics of Higher Education, and Health Economics.
Differences in obtaining a vaccine vary based on a multitude of factors including perceptions of vaccine safety, efficacy and willingness to pay (WTP). This study focuses on parent perceptions toward a vaccine for COVID-19 including their WTP decisions for their children and themselves. A mixed methods design using a cross-sectional survey was used to assess the perceptions of US parents, with children under 18, in response to the COVID-19 pandemic. The survey was administered online in November 2020 and 584 final responses were collected. The questionnaire consisted of approximately 37 closed and open-ended questions regarding personal background information; awareness, knowledge, and experience of the virus; perception toward vaccines and COVID-19; and the contingent valuation of a hypothetical COVID-19 vaccine. WTP was found to be higher for children and a direct relationship between the number of children and WTP was observed. Parents were willing to pay US$228–$291 for a vaccine for themselves and US$243–US$321 for their children. A positive impact on WTP was found with self-reported parent health status but not children. The findings of this study have important implications for policy programs which require detailed cost-benefit analyses. WTP for a COVID-19 vaccine is crucial to determine the partial benefits of vaccinating to reduce the risk of repetitive widespread outbreaks.

Our objective was to estimate the individual willingness to pay (WTP) for a COVID-19 vaccine and evaluate its predictors in the United States. A double-bounded dichotomous choice contingent valuation with open-ended question technique was implemented based on the responses to a national survey administered during the first week of November 2020. The final sample size was 1285. The results showed that individual WTP values increased with income, whether a household member had any pre-existing condition, and perceived threat of the virus. The vaccine efficacy rate and duration of protection were found to be important factors for the respondents. The mean WTP for a vaccine with a 95 percent efficacy rate and 3-year protection (US$318.76) was approximately 35 percent greater than the vaccine with a 50 percent efficacy rate and 1-year protection (US$236.85). The initial aggregate direct benefit of the current vaccination program was estimated to be between 20 and 35.6 billion US dollars depending on the vaccine protection duration.

Accelerated coastal erosion and elevated risks of flooding due to global warming put enormous burden on the ecosystems and economic health of coastal communities. Optimal policies to lessen these negative impacts require an estimation of their costs and benefits. The aim of this paper is to calculate the costs of beach erosion and flood risk through the valuation of property prices in Hilton Head Island, a barrier island located in South Carolina, USA. Spatial lag hedonic pricing was introduced in order to account for spatial autocorrelation in the dataset. The results show that properties that are located within the zone of high, or very high, flood risk experience a 15.6% reduction in value. The implicit price of being located close to an eroded beach is approximately 26% of the price of an oceanfront property. However, this negative impact on property value diminishes with distance from the shoreline.

Climate change has been impacting beach quality negatively for years. The gradual increase in sea level has been slowly diminishing the Atlantic coastline by eroding beaches and worsening coastal flooding. Narrowing beach width, one of the most important attributes of beach quality, has been a major concern for policy makers, local residents and visitors as lower beach quality has environmental and economic consequences. Filling the beaches with sand under beach replenishment projects has been widely used to treat this problem. The purpose of this paper is to estimate the economic value of beach width using the past residential property prices in Hilton Head Island, SC. Spatial error hedonic price method was adopted to account for spatial dependency among error terms. The results of this study show that beach width has significant influence on the values of neighboring properties that are located within 633 feet of the shoreline. An additional foot of beach width would add as much as $3,012 to the value of an oceanfront residential property. Without an accurate estimation of the economic value of beach width, cost-benefit analyses of beach nourishment and other shoreline management projects would be incomplete.
