Using data from Round 11 of the European Social Survey (ESS11), we investigate the impact of adult height, an anthropometric marker of cumulative biological status, on the levels and distribution of subjective well-being (SWB) across Europe. Through the lens of the Anna Karenina principle, we apply reweighted Recentered Influence Function (RIF) Oaxaca-Blinder decompositions and height-stratified regressions to isolate the compositional and structural drivers of happiness mean and variance gaps between the shortest and tallest quartiles. Aggregate decompositions reveal that the tallest individuals report higher average happiness and significantly lower well-being variance. These gaps are driven almost entirely by explained compositional advantages, demonstrating that the lower happiness inequality of the tall stems from a superior accumulation of variance-compressing health, economic, and social assets rather than differing structural returns. However, stratified regressions uncover a structural paradox: while the tallest quartile exhibits a higher unconditioned baseline variance, positive health and social assets function as potent variance-compressing anchors that homogenize their realized well-being. Conversely, labor market precarity, health shocks, aging, and macro-regional vulnerabilities widen the happiness dispersion of the shortest individuals. Height thus appears to operate as a protective structural guard against misery and volatility rather than a direct engine for boosting bliss. These findings suggest that the height premium manifests as an acquired privilege of structural insulation, shifting welfare policy priorities toward targeted public healthcare and institutional labor floors to shield biologically vulnerable demographics from volatile welfare fluctuations

In integrated multi‐trophic aquaculture (IMTA), species from different trophic levels are raised in proximity to one another and the co‐products (organic and inorganic wastes) of one cultured species are recycled to serve as nutritional inputs for others. IMTA can reduce the ecological impacts near aquaculture operations, improve social perceptions of aquaculture and provide financial benefits for aquaculture producers via product diversification, faster production cycles and price premiums on IMTA products. We review aspects of IMTA’s economic potential and market acceptance and consider ways to address the current gaps in our understanding. We find that adopting IMTA raises the assimilative capacity of the farm and that IMTA substantively reduces the environmental cost of aquaculture. Moreover, integrating extractive species (e.g. invertebrates and/or seaweeds), with existing fed‐monoculture operations, can increase farm profits. The presence of positive public attitudes towards IMTA, as expressed by a willingness to pay a premium for its products, can further increase the profitability of adopting IMTA. Areas requiring more economic research include the development of comparative bioeconomic models of IMTA and the evaluation of competing production systems and their ability to internalize externalities to demonstrate the true value of IMTA to society. Further exploration of economic incentives, such as instruments needed to foster adoption of IMTA, and investigation of marketing opportunities, such as promoting the eco‐certification of IMTA products, are also needed. Our paper aimed to inform economists and non‐economists alike about the latest developments in IMTA economics, and spur further research on critical topics concerning this important subject.

The willingness to pay (WTP) for reductions in the risk of moose-vehicle collision in Newfoundland (the insular portion of Newfoundland and Labrador, Canada) is estimated using the Contingent Valuation Method. Our estimations use the information obtained from a double-bounded payment format and let us examine the existence of scale heterogeneity (dependent on response certainty levels), question effects such as anchoring and shift effects, and the effects of accounting for the former on the latter. Our main findings are that the estimated WTP tends to be lower in the models that account for scale heterogeneity but that correction makes little difference in models that fully correct for the question effects involved in the use of the double-bound payment format. Accounting for scale heterogeneity does change, however, the way in which corrections for question effects influence the size of welfare estimates. In particular, it reduces the variability of welfare measures across treatments of these question effects, yielding an estimate of WTP close to the one obtained from using the single-bounded portion of the data.
