{"title":"Seafarer market structure analysis of Korean merchant shipping in COVID-19","authors":"Yong An Park ,&nbsp;Tsz Leung Yip ,&nbsp;Sung Rye Hu ,&nbsp;Hong Gyue Park","doi":"10.1016/j.ajsl.2023.06.003","DOIUrl":"https://doi.org/10.1016/j.ajsl.2023.06.003","url":null,"abstract":"<div><p>COVID-19 pandemic clearly demonstrates that seafarers are essential for sustaining world shipping services and global supply chain. Understanding the characteristics of supply and demand in seafarer market will be a solution for the bottleneck issues of seafarer change and shipping services. This paper explores the supply and demand of seafarer market in Korea and evaluates the effects of COVID-19 on both supply and demand sides of Korean seafarers by adopting regression models with panel data for the supply and time series data for the demand. First, this paper finds that the effects of COVID-19 are negative in the demand of Korean seafarer market even with the wider increase of tonnage of the Korean flagged ships in 2020. The demand shock seems to be resulted by the traveling restriction and stricter immigration measures to travellers after the announcement of COVID-19 pandemic. Second, supply in the regression models of panel data is affected negatively after declaration of the COVID-19 pandemic in 2020. The COVID-19 pandemic may trigger the hesitation of seafaring due to the travelling restriction and bottlenecks from seafarer changes onboard. Besides these findings, the correlation coefficients between the number of Korean seafarers of merchant ships and merchant fleet illustrate a diverse relationship between the two. The expansion of Korean ocean-going fleet is accompanied by the decrease of Korean seafarers on the Korean flag. The employment of foreign seafarers since 1992 has resulted in the continual decrease of ratings employment in the Korean flagged ships. The inflow of foreign deck officers in the Korean flagged ships after 2005 could lessen the officer deficiency caused by high separation rate of Korean deck officers. This inflow implies that seafarer market in a country not only affects global seafarer market in the world through the changes of seafarer supply and demand in the country, but is affected by the global market. The dual markets of Korean seafarers in ocean-going and coastal shipping present the following phenomena: severe aging of seafarers in coastal shipping and wider difference in welfare level of seafarers between the two. Further research on wage and career advancement of Korean seafarers would widen and deepen our understanding on seafarer market both for Korea and the rest of the world.</p></div>","PeriodicalId":46505,"journal":{"name":"Asian Journal of Shipping and Logistics","volume":"39 3","pages":"Pages 39-47"},"PeriodicalIF":3.1,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49897643","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, since there is no standardized way to define these categories, risk matrix with its strength of being straightforward to use and easy to interpret has inherent uncertainties including objective categorization determination and consistency of decisions on frequency and consequence among different users, which usually results in multiple risk outcomes leading to incorrect conclusion about decision making on risk initiated from accidents.</p><p>The purpose of the study is to predict a long term risk of maritime accident using a 5 × 5 probabilistic risk matrix where each category of frequency and consequence is probabilistically estimated by a Markov chain model. The proposed method to calculate accident risk is illustrated using maritime accident data over 2016–2020 years. The findings are that the most probable frequency and consequence ranges of maritime accidents will be between 182 and 235 with probability of 0.3878 and between 6.8 and 11.6 fatalities with probability of 0.3791, respectively. The expected risk value was computed as 4.6506 on a scale of 2–10. For the validation of the proposed method 90 %, 95 %, and 99 % confidence intervals were constructed which were shown to contain the predicted risk value.

Therefore, exploring the factors affecting the intentions to stay in jobs of the crowdshippers is of great significance to maintain and sustainably develop the last-mile delivery service. Based on the Social Exchange Theory, we hypothesize that benefits (economic benefits, professional reputation, and job autonomy) and costs (risks and stress at work) have an effect on crowdshippers’ intentions to continue participating in last-mile delivery service in Vietnam. We also look for differences in motivations to stay in job between full-time and part-time workers. Survey data from 428 crowdshippers were analyzed using SmartPLS. The research findings indicate that economic benefits and work autonomy (benefits) have positive influences on intention to continue participating in crowd logistics, while risks and job stress (cost) have negative effects on the intention of crowsdhippers to continue their work. In addition, research findings also uncover that differences in motivation (perception of benefits and costs) to stay in job between full-time and part-time workers also affect their intentions. Although reputation did not show a significant impact on the crowdshippers’ intentions to continue participating in crowd logistics, it was discovered that reputation has a positive effect on full-time crowdshippers’ intentions to continue working.

According to the results, electric power consumption is expected to increase at an annual average of 4.9 % until 2040, exceeding the predicted annual 4.7 % increase in throughput during the same period.
