Purpose: This study seeks to explore the impact of COVID-19-induced boredom, a prevalent form of pandemic-related stress, on travel motivation and post-pandemic travel intentions. Additionally, it examines the interplay among travel motivation, travel constraints, and the willingness to pay more for travel experiences in the post-pandemic context. Methods: A PLS-SEM analysis was conducted to analyze the data. Data collection took place through an online survey in February and March 2021, with a total of 575 respondents participating. Participants provided responses regarding their current levels of boredom due to COVID-19, five different travel motivations, seven travel constraints, and their post-pandemic travel intentions. Additionally, participants were asked about their willingness to pay more for travel. Results: This study highlights the significant role of COVID-19-induced boredom in predicting post-pandemic travel intentions and the willingness to pay more for travel. Contrary to previous perceptions, boredom emerges as a driving factor, enhancing travel intentions during the pandemic. Additionally, relaxation becomes the primary motivation for travel during COVID-19, and structural constraints exert a noticeable impact on travel intentions, challenging previous assumptions. Stress levels directly influence the willingness to pay more during travel experiences, expanding the understanding of additional payment behavior in the context of travel. Conclusion: This study offers practical insights for tourism stakeholders. Recognizing and addressing boredom in marketing strategies, implementing aggressive additional payment options, and focusing on relaxation-oriented travel products are recommended to cater to post-pandemic traveler preferences and revive the tourism industry effectively.

Where an insurer has unreasonably refused to pay a claim or paid it after unreasonably delay, the existing law in England does not provide a remedy for the insured. Accordingly, the insured is not entitled to damages for any loss suffered as a result of the insurer's unreasonable delay. This legal position differs from the law in Scotland and most major common law jurisdictions. LC thought that the legal position in England is anomalous and out of step with general contractual principles. LC considered that a policyholder should have a remedy where an insurer has acted unreasonably in delaying or refusing payment of claim, and, therefore, recommended a statutory implied term in every insurance that the insurer will pay sums due within a reasonable time and breach of that term should give rise to contractual remedies, including damages. More detailed recommendations of LC are as followings. First, it should be an implied term of every insurance contract that, where an insured makes a claim under the contract, the insurer must pay sums due within a reasonable time. Secondly, a reasonable time should always include a reasonable time for investigating and assessing a claim. Although a reasonable time will depend on all the relevant circumstances, for example, the following things may need to be taken into account, that is, (1) the type of insurance, (2) the size and complexity of the claim, (3) compliance with any relevant statutory rules or guidance, and (4) factors outside the insurer's control. Thirdly, if the insurer can show that it had reasonable grounds for disputing the claim(whether as to pay or not, or the amount payable), the insurer does not breach the obligation to pay within a reasonable time merely by failing to pay the claim while the dispute is continuing. In those circumstances, the conduct of the insurer in handling the dispute may be a relevant factor in deciding whether the obligation was breached and, if so, when. Fourthly, Normal contractual remedies for breach of contract should be available for breach of the implied term to pay sums due within a reasonable time. Finally, In non-consumer insurance contracts, the insurer should be permitted to exclude or limit its liability for breach of the obligation to pay sums due within a reasonable time, unless such breach was deliberate or reckless, and such an insurer's right to contract out will be subject to satisfying the transparency requirements.

비시장재 가치평가기법 중의 하나인 조건부 가치평가법(CVM)은 응답자들이 가상적 환경질 변화에 대한 지불의사를 표시할 때 현실적 예산제약조건에 기초하지 않기 때문에 과다평가피는 경향이 있다는 비판을 받아왔다. 본 연구는 여행비용법에 기초한 레크리에이션 수요함수와 조건부 가치평가법에 기초한 지불의사함수를 효용이론의 틀 안에서 결합 추정하는 과정에서 CVM 응답과 관련된 소득조정계수(income calibration factor)를 추정함으로써 CVM의 유효성과 타당성을 분석하고자 한다. 수요함수와 지불의사함수의 결합추정모형은 최근 새만금 사업과 관련하여 논란이 되고 있는 만경강 유역의 수질개선을 사례로 분석하였다. 결함추정의 결과 중요 경제변수인 가격과 소득 그리고 수질변수들은 경제이론이 설명하는 바대로 수요함수와 지불의사 함수에 통계적으로 유효한 영향을 미쳤다. 소득조정계수 역시 통계적으로 1과 다르지 않은 것으로 나타나 실제 레크리에이션 수요행동에 비추어 가상적 수질개선에 대한 지불의사를 진술하는데 있어서, 적어도 예산과장의 측면에서 체계적인 편의는 관찰되지 않았다. 이러한 본 연구의 결과는 주의 깊게 설계된 CVM 연구가 비시장재인 환경질의 변화에 대한 소비자들의 지불의사를 도출하는데 유용한 자료를 제공할 수 있음을 실증적으로 시사하고 있다.

Contingent valuation method(hereafter CVM) is generally believed to be one of the most popular methods used for quantifying the value of non-market goods or services particularly by asking respondents of willingness to pay. This study deals with how to use CVM in calculating the value of mobile telephone service by suggesting methodology of estimation and eliminating biases. This study represents an attempt to estimate the WTP(Willingness To Pay) of the mobile telephone service using the face-to-face interview which is the qualitative technique is used. In this study, by using the single bound dichotomous choice model(SBDC) in order to analyze the valuation of mobile telephone service, WTP was estimated. Also we analyze the factors to pay for mobile service in which it becomes the important factor of demanding services. We used logit model. In order to provide robust estimates of WTP, we have used the Method of Montecarlo Simulation. Consequently, consumers showed that WTP about the mobile communications service is generally high. And it could know that the WTP will fell down as the specialized knowledge about the mobile communications frequency was high. It will be able to become the important part to not only the business carrier but also the policy maker to estimate the economic value of mobile telephone service.

The main purpose of this study is to find the factors affecting the consumer goods buyers' choice on e-commerce sites in Vietnam. By using the quantitative method, the paper examines the theoretical research model and tests four hypotheses. The sample was drawn from the population of e-commerce sites in Vietnam comprising about 1,000 respondents. This study used the questionnaire method to collect primary data to test the hypotheses. Data analysis of the questionnaire was done using SPSS. The results show that there is a correlation between personal preferences of consumers on colors and brands and their actual final choice on e-commerce sites in Vietnam. The most important factor affecting the consumer goods buyers' choice on e-commerce in Vietnam is the brand of E-commerce site, following by the color and position. Among all educational groups, respondents with a Master degree pay the biggest attention to the site's color attribute, and those with a Bachelor degree pay more attention to the brand attribute. Women pay much more attention to the location of the products on the screen than men, as do consumers with a PhD degree, over respondents with a Bachelor or Master degree, and foreigners over Vietnamese consumers.

This inductive study seeks to establish a conceptual background for theoretical development regarding talent misuse in the context of small and medium-sized enterprises (SME). The two objectives for the goal were (1) to explore and build a list of unethical treatment practiced on young talents; (2) to establish new framework for the special context or refining the existing framework on employee mistreatment. For the first goal, an attempt was made to develop a list of mistreating behavior by collecting and analyzing cases of ethical disputes. Analyses on 64 cases of talent mistreatment, namely 'passion pay', was conducted to present a conceptual ground for further investigation. Then, for the second objective, this study has proposed an integrative approach for assessing these ethical elements. The ethical implications were discussed based on an assessment conducted using three theories of ethics. Finally, a cluster analysis further shows the emergence of three groups based on the mistreating behaviors. We observed seven different mistreatment behaviors under four categories of mistreatment practices. Additionally, the cluster analysis results imply that talent mistreatment may be rooted in work characteristics. Organizational size may provide some contextual reasoning, but the extent to which this factor interacts with work characteristics left unclear.

In a long-run, a price reduction of shine muscat that is one type of grapes is expected due to an increase of cultivated area. To come up with this problem, expanding exports of shine muscat considering that domestic demand is restricted in Korea. This study investigates the China consumers preference for shine muscat from Korea since exports to China have increased a lot after the quarantine agreement in 2015. Specifically, this paper analyzes a probability of shine muscat exports to China based on willingness to pay (WTP). Moreover, we derive long-run and short-run export strategies for Korean shine muscat. Our results show that a probability of exports to China is high. However, this probability is lowered at the sample of consumers who have the experience of tasted shine muscat. Considering the relative important characteristic for buying shine muscat at the sample of eating experienced consumers in China is sweetness, there is a need to develop cultivation technologies for enhancing sweetness to attain a sustainable development in the grape sector of Korea.
