Title: Recent Trend of Seafood Consumption in South Korea: Generational Insights and Strategies for Revitalization Author(s): Han, Kiuk; Jung, Yeonhee; Jung, Pilgyu; Chung, Keunsuk Abstract: Drawing on consumer survey data and long-term statistics (1962-2020), we examine recent trends in South Korea's seafood consumption and consider policy options to revitalize demand in a mature market. Our study identifies a clear gap between stated seafood preferences and actual consumption behavior, particularly among Millennials and Generation Z (the MZ generation). Ordered-probit estimates from a nationally stratified survey of 1,000 adults show that, although Generation MZ expresses relatively positive preferences for seafood, they consume it less frequently relative to meat than do Baby Boomers and Generation X. This gap is linked primarily to perceived inconvenience and price, whereas older cohorts place greater emphasis on health benefits and value of seafood. Revitalizing seafood consumption therefore requires policies that lower consumer-side barriers related to price and convenience. Priorities may be put on developing easy-to-prepare seafood products, fostering innovation in processing and distribution, and strengthening efficient e-commerce platforms to engage younger consumers. These demand-side innovations depend on stable, standardized supply systems that can be institutionally supported through sustainability certification such as Marine Stewardship Council (MSC) and Aquaculture Stewardship Council (ASC). Aligning generation-targeted demand strategies with sustainable coastal production systems may therefore contribute to long-term demand recovery in the seafood sector.

Title: Short-term forecasting of seafood exports: a hybrid approach for strategic trade planning Author(s): Han, Kiuk; Won, Eunsong; Chung, Keunsuk Abstract: In this study, a short-term forecasting model for seafood exports is developed by integrating econometric and deep-learning methods. Using Korea's monthly data from January 2000 to December 2023, we identified five key predictors-export price, won-yen exchange rate, Brent oil price, real gross domestic product (GDP) per capita, and seafood production-through a systematic feature selection process. Dynamic regression confirmed their significant effects on export volumes, while long short-term memory (LSTM) and gated recurrent unit (GRU) models produced accurate forecasts for January 2022 through to December 2023. The results highlight product-specific dynamics: seaweed snack exports are highly sensitive to global income and demand, reflecting their income-elastic nature, whereas tuna exports are mainly shaped by production capacity and relative price competitiveness. By simultaneously identifying key export determinants and generating forward-looking forecasts, this framework combines interpretability with predictive accuracy, offering practical implications for tailored trade strategies, proactive risk management, and sustainable policy planning in volatile global seafood markets.

Title: Fail to win: How schadenfreude and competitive traits predict download intention in mobile game fail ads Author(s): Moon, Joonhyun; Kim, Yeolib; Choi, Boreum; Choi, Hanbyul Abstract: In mobile game advertising, failure‐depicting advertisements, which intentionally showcase unsuccessful gameplay scenarios, have emerged as an unexpectedly effective promotional strategy. This study examines the psychological mechanisms underlying the effectiveness of fail advertisements, with particular attention to the emotional response of schadenfreude and the influence of individual differences in competitiveness. Drawing on prior research on schadenfreude and Trait Activation Theory, we propose that schadenfreude experienced in response to fail ads is positively related to individual competitiveness and is, in turn, associated with higher download intention. We conducted two vignette‐based experimental studies to test this theoretical framework. Study 1 (N = 241) demonstrates that hypercompetitiveness predicts schadenfreude, which in turn impacts download intention, while general competitiveness only influences schadenfreude indirectly through hypercompetitiveness. Study 2 (N = 247) extends these findings by showing that perceived game difficulty moderates the experience of schadenfreude, such that failures occurring in reasonably challenging scenarios are associated with greater schadenfreude than those in extremely difficult ones. These findings contribute to the literature on the impact of schadenfreude and individual competitiveness on consumer responses. Marketers can enhance ad effectiveness by calibrating difficulty and targeting hypercompetitive consumers with fail‐based narratives.

Title: International Trade and the Currency Composition of Corporate Debt Author(s): Jiao, Yang; Kwon, Ohyun; Lee, Saiah Abstract: This paper investigates firm-level linkage between international finance and trade. Specifically, we present evidence that Korean firms rely more on financing in foreign currency if there is a positive export shock. We address the crucial endogeneity prob lem by capitalizing on South Korea’s as well as its trading partners’ demand shocks. We further show that global supply chains also play an important role as higher im portedintermediateinputsharesinducelowerforeigncurrencydebtshares. Ourfind ings point to a firm-level hedging channel and are pertinent to exchange rate policies that aim to reduce a (developing) country’s vulnerability to exchange rate shocks.
