What accounts for the growth of US top income inequality? This paper proposes a hierarchical redistribution hypothesis. The idea is that US firms have systematically redistributed income to the top of the corporate hierarchy. I test this hypothesis using a large-scale hierarchy model of the US private sector. My method is to vary the rate that income scales with hierarchical rank within modeled firms. I find that this model is able to reproduce four intercorrelated US trends: (1) the growth of the top 1% income share; (2) the growth of the CEO pay ratio; (3) the growth of the dividends share of national income; and (4) the ‘fattening’ of the entire income distribution tail. This result supports the hierarchical redistribution hypothesis. It is also consistent with the available empirical evidence on within-firm income redistribution.

What explains the power-law distribution of top incomes? This paper tests the hypothesis that it is firm hierarchy that creates the power-law income distribution tail. Using the available case-study evidence on firm hierarchy, I create the first large-scale simulation of the hierarchical structure of the US private sector. Although not tuned to do so, this model reproduces the power-law scaling of top US incomes. I show that this is purely an effect of firm hierarchy. This raises the possibility that the ubiquity of power-law income distribution tails is due to the ubiquity of hierarchical organization in human societies.

Regional Divergence

Abstract After more than a century of convergence, the economic fortunes of rich and poor regions of the United States have diverged dramatically over the last 40 years. Roughly a third of the US population now lives in metropolitan areas that are substantially richer or poorer than the nation as a whole, almost three times the proportion that did in 1980. In this paper I use counterfactual simulations based on Census microdata to understand the dynamics of regional divergence. I first show that regional divergence has primarily resulted from the richest people and places pulling away from the rest of the country. I then estimate the relative contributions to regional divergence of two major socioeconomic trends of recent decades: the sorting of people across metro areas by income level and the national rise in income inequality. I show that the national rise in income inequality is sufficient on its own to account for more than half of the observed divergence across regions, while income sorting on its own accounts for less than a quarter. The major driver of regional economic divergence is national-level income dispersion that has exacerbated preexisting spatial inequalities.

Over Time

In this study, we explore the long-term trends of floodplain population dynamics at different spatial scales in the contiguous United States (U.S.). We exploit different types of datasets from 1790–2010—i.e., decadal spatial distribution for the population density in the US, global floodplains dataset, large-scale data of flood occurrence and damage, and structural and nonstructural flood protection measures for the US. At the national level, we found that the population initially settled down within the floodplains and then spread across its territory over time. At the state level, we observed that flood damages and national protection measures might have contributed to a learning effect, which in turn, shaped the floodplain population dynamics over time. Finally, at the county level, other socio-economic factors such as local flood insurances, economic activities, and socio-political context may predominantly influence the dynamics. Our study shows that different influencing factors affect floodplain population dynamics at different spatial scales. These facts are crucial for a reliable development and implementation of flood risk management planning.

This paper measures the development of the national income share of the bioeconomy for 28 European Union Member States (MS) and 16 industries of BioMonitor scope from 2005 to 2015. The paper proposes a model which includes the up- and downstream linkages using Input-Output tables. The results show that for the majority of the MS the value added of the up- and downstream sector is at the band of 40%–50% of the total bioeconomy value added and has on average increased since the financial crisis.

Urbanization is a complex land transformation not explicitly resolved within large-scale climate models. Long-term timeseries of high-resolution satellite data are essential to characterize urbanization within land surface models and to assess its contribution to surface temperature changes. The potential for additional surface warming from urbanization-induced land use change is investigated and decoupled from that due to change in climate over the continental US using a decadal timescale. We show that, aggregated over the US, the summer mean urban-induced surface temperature increased by 0.15 °C, with a warming of 0.24 °C in cities built in vegetated areas and a cooling of 0.25 °C in cities built in non-vegetated arid areas. This temperature change is comparable in magnitude to the 0.13 °C/decade global warming trend observed over the last 50 years caused by increased CO2. We also show that the effect of urban-induced change on surface temperature is felt above and beyond that of the CO2 effect. Our results suggest that climate mitigation policies must consider urbanization feedback to put a limit on the worldwide mean temperature increase.

Solar Thermochemical

Hydrogen produced from renewable energy has the potential to decarbonize parts of the transport sector and many other industries. For a sustainable replacement of fossil energy carriers, both the environmental and economic performance of its production are important. Here, the solar thermochemical hydrogen pathway is characterized with a techno-economic and life-cycle analysis. Assuming a further increase of conversion efficiency and a reduction of investment costs, it is found that hydrogen can be produced in the United States of America at costs of 2.1–3.2 EUR/kg (2.4–3.6 USD/kg) at specific greenhouse gas emissions of 1.4 kg CO2-eq/kg. A geographical potential analysis shows that a maximum of 8.4 × 1011 kg per year can be produced, which corresponds to about twelve times the current global and about 80 times the current US hydrogen production. The best locations are found in the Southwest of the US, which have a high solar irradiation and short distances to the sea, which is beneficial for access to desalinated water. Unlike for petrochemical products, the transport of hydrogen could potentially present an obstacle in terms of cost and emissions under unfavorable circumstances. Given a large-scale deployment, low-cost transport seems, however, feasible.

Background: There are limited data about the racial difference in the characteristics of chronic obstructive pulmonary disease (COPD) patients who are treated at clinics. We aimed to compare sociodemographic and clinical characteristics between US and Korean COPD patients using large-scale nationwide COPD cohorts. Methods: We used the baseline demographic and clinical data of COPD patients aged 45 years or older with at least a 10 pack-per year smoking history from the Korean COPD Subtype Study (KOCOSS, n = 1686) cohort (2012–2018) and phase I (2008–2011) of the US Genetic Epidemiology of COPD (COPDGene) study ( n = 4477, 3461 were non-Hispanic whites [NHW], and 1016 were African Americans [AA]). Results: Compared to NHW, AA had a significantly lower adjusted prevalence ratio (aPR) of cough >3 months (aPR: 0.67; 95% CI [confidence interval]: 0.60–0.75) and phlegm >3 months (aPR: 0.78, 95% CI: 0.70–0.86), but higher aPR of dyspnea (modified Medical Round Council scale ⩾2) (aPR: 1.22; 95% CI: 1.15–1.29), short six-minute walk distance (<350 m) (aPR: 1.98; 95% CI: 1.81–2.14), and poor quality of life (aPR: 1.10; 95% CI: 1.05–1.15). Compared to NHW, Koreans had a significantly lower aPR of cough >3 months (aPR: 0.53; 95% CI: 0.47–0.59), phlegm >3 months (aPR: 0.75; 95% CI: 0.67–0.82), dyspnea (aPR: 0.72; 95% CI: 0.66–0.79), and moderate-to-severe acute exacerbation in the previous year (aPR: 0.73; 95% CI: 0.65–0.82). NHW had the highest burden related to chronic bronchitis symptoms and cardiovascular diseases related to comorbidities. Conclusion: There are substantial differences in sociodemographic characteristics, clinical presentation, and comorbidities between COPD patients from the KOCOSS and COPDGene, which might be caused by interactions between various intrapersonal, interpersonal, and environmental factors of the ecological model. Thus, a broader and more comprehensive approach would be necessary to understand the racial differences of COPD patients.

Using level of income inequality, the clustering of post-communist countries of the Central and Eastern Europe is carried out by the following indicators: Gini index, share in the national income of the second quintile group, share in the national income of the third quintile group, share in the national income of the fourth quintile group, share in the national income of 10% of the poorest, share in the national income of 20% of the richest.,Сluster analysis (k-means method), in the programming environment Statistica is used as analysis tool and five clusters are obtained. The first cluster includes 8 countries (Albania, Hungary, Poland, Bosnia and Herzegovina, Czech Republic, Сroatia, Russia, Slovakia) is characterized by sufficiently low level of income inequality and can be explained by flow of foreign investment and business transnationalization contributing to the increase of incomes of the main population groups of these countries. The second cluster includes 4 countries (Belarus, Slovenia, Ukraine, Moldova) and is characterized by comparatively low level of income inequality, but high level of property inequality due to heredity, аccumulated wealth та concentration of physical and financial capital by so called «oligarchic clans». The third cluster includes 5 countries (Bulgaria, Montenegro, Macedonia, Romania, Serbia) and is characterized by medium level of income inequality. The fourth and fifth clusters include so called «Baltic tigers» (Latvia, Lihuania, Estonia) and is characterized by high level of income inequality as the result of the occurrence of «excess profits» of financial assets owners. In order to decrease the income inequality in the investigated countries, the following measures are proposed: for the countries of the first cluster to accelerate deconcentration of capital ownership by «spaying» (redemption) of privatized enterprises shares by all categories on preferential terms (so called «ESOP programs»); for the countries of the second cluster to implement progressive tax scale where the tax rate for different groups of population vary depending on the income received and citizens with the lowest incomes (at the level of subsistence minimum or minimum wage) do not pay individual taxes at all; for the countries of the third cluster to cope with «shadow» economy and informal unemployment; for the counties of the fourth and fifth clusters to decrease tax burden on private entrepreneurs and thus stimulate self-employment.

The article analyzes the prospects for US-North Korean and inter-Korean relations, taking into account the completed policy review of the new US administration towards the Democratic People&apos;s Republic of Korea (DPRK), as well as the results of the President of the Republic of Korea Moon Jae-in’s trip to Washington in May 2021 and his talks with US President Joe Biden. It is concluded that the “new&quot; course proposed by the United States in relation to the DPRK will not lead to a solution to the nuclear problem of the Korean Peninsula and will interfere with the normalization of inter-Korean relations. During his visit to the US President Moon failed to obtain the US consent on ROK more “independent policy” toward North Korea. In spite of lavish investments into US economy and other concessions, Seoul was forced to promise to coordinate his approaches to the DPRK with US and Japan and support US position on Taiwan straits and South China Sea. The author argues that in the current conditions, the introduction of a regime of arms limitation and arms control in Korea should be a necessary stage on the way to complete denuclearization of the peninsula. The transition to a such method of the settlement of the nuclear problem could lead to the resumption of the negotiation process, mutual concessions, including reductions in the level of military-political confrontation, partial or large-scale lifting of economic sanctions in exchange for North Korea&apos;s restrictions of its nuclear weapon and missile systems.

Potential Benefits

It is clear to everyone that investment in the agricultural sector in developing countries is one of the most effective ways to reduce poverty and hunger in the world. Agricultural investment can generate a wide range of development opportunities. However, these benefi ts cannot be expected to arise automatically. Some forms of large-scale investment pose significant risks to investor states. It should be noted, however, that, despite discussions about the potential benefits and risks of international investment, there is still no evidence of negative actual consequences for the countries receiving investments. This article examines the issues of investment activity in relation to developing countries using the example of US agribusiness entities.
