Obesity of politicians and corruption in Ukraine in 2000–2020– Reply

We collected 469 frontal face images of Ukrainian cabinet ministers who were in office in 2000–2020. For each image, the minister's body mass index was estimated using a computer vision algorithm. The time series of median estimated body mass index of cabinet ministers co-moves over time with two existing measures of corruption – World Bank worldwide governance indicator Control of Corruption, and the discrepancy between the quantity of luxury wristwatches exported from Switzerland to Ukraine (reported by Swiss statistics) and the corresponding quantity imported by Ukraine from Switzerland (reported by Ukrainian statistics).     

Luxury products for the circular economy? A case study of Bang & Olufsen

This paper examines whether luxury products can support a circular economy. This is done through a literature review of luxury products and the links to circular economy, as well as a case study of Bang & Olufsen (B&O). The literature review revealed links between some of the core characteristics of luxury products and the circular economy. This included aspects such as the high quality, durability, service schemes, extended warranties, and large aftermarkets. The case study supports the links between the inner circles in the circular economy (maintenance, repair, and reuse) and some of the core characteristics of luxury products. B&O produces products with a long lifespan, has extended warranties, repair and service schemes, spare part availability for 8 years, an aftermarket, and leasing schemes. B&O also does reconditioning of components for its repair loop, conducts dismantling tests, marks plastic parts, and has a negative list that excludes certain hazardous components.     

The effects of power on consumers’ evaluation of a luxury brand's corporate social responsibility

This paper examines how power affects consumers’ responses to corporate social responsibility (CSR) initiatives of luxury brands. The results of three studies show that high‐power individuals evaluated a luxury brand's CSR campaign more positively than low‐power individuals. High‐power individuals viewed CSR activities as being more fluent than low‐power individuals. This study further demonstrates that power influences consumers’ responses to nonluxury brand's CSR activities. Low‐power individuals, who are more receptive to warmth, evaluated nonluxury brand's CSR more favorably rather than high‐power individuals.     

Stability and Segregation in Group Formation

This paper presents a model of group formation based on the assumption that individuals prefer to associate with people similar to them. It is shown that, in general, if the number of groups that can be formed is bounded, then a stable partition of the society into groups may not exist. (A partition is defined as stable if none of the individuals would prefer be in a different group than the one he is in.) However, if individuals' characteristics are one-dimensional, then a stable partition always exists. We give sufficient conditions for stable partitions to be segregating (in the sense that, for example, low-characteristic individuals are in one group and high-characteristic ones are in another) and Pareto efficient. In addition, we propose a dynamic model of individual myopic behavior describing the evolution of group formation to an eventual stable, segregating, and Pareto efficient partition.

Environmental protection versus economic growth

This paper presents and analyses the differences in the eco-models implemented worldwide （such as whether and how carbon taxes being ＂recycled＂）, or in their efficiency parameters （inconsistent parameter values that account for different results）. This is the assumption that a real tradeoff exists between the production of environmental goods. The present article empirically proves that something must be given up in order to gain something else, and once equations are specified to trace out the path of the economy over time, the natural economic formulation of such equations will embody the notion of economic and bio-tradeoffs.

Reviewing Oates' insights in a repeated game setting

This paper analyzes the optimal assignment of public good policies to layers of a federal system in a repeated game setting. Under a centralized regime, public goods are financed jointly across regions, and a federal legislature decides on the regional quantities. Under a decentralized regime, public goods are financed locally, and governments play a non-cooperative provision game. We find that a centralized (decentralized) regime is more likely to provide the efficient public good policies in case spillovers are small (large).
