The concept of environmental sustainability aims to achieve economic development while achieving a sustainable environment. The inverted U-shape relationship between economic growth and environmental quality, also called Environmental Kuznets Curve (EKC), describes the correlation between economic growth and carbon emissions. This study assesses the role of agriculture and energy-related variables while evaluating the EKC threshold in 54 African economies, and income groups, according to World Bank categorization, including low income, lower-middle, upper-middle, and high-income in Africa. With 1990–2015 panel data, the results are estimated using panel cointegration, Fully Modified Ordinary Least Square (FMOLS), and granger causality tests. The results are: (1) The study validated the EKC hypothesis in the low-income, lower-, and upper-middle-income economies. However, there is no evidence of EKC in the full African and high-income panels. Furthermore, the turning points of EKC in the income group are meagerly low, showing that Africa could be turning on EKC at lower income levels. (2) The correlation between agriculture with CO2 is found positive in the high-income economy. However, agriculture has a mitigation effect on emissions in the lower-middle-income and low-income economies, and the full sample. Also, renewable energy is negatively correlated with emissions in Africa and the high-income economy. In contrast, non-renewable energy exerts a positive effect on emissions in all income groups except the low-income economies.

Abstract The use of renewable energy improves environmental quality by reducing carbon emission and influence economics growth where carbon emission also effect economic growth of a country. The economic theory of tourism also indicates that tourism development enhance economic growth though spillovers as well contribute to climate change. The inflow of FDI and financial development enhance economic growth however its also effect environmental quality. Based on the ongoing debate, the present research trying attempts to explore the effect of CO2 emission and renewable energy consumption, FDI and financial development on economic growth in different income grouped countries to know whether these impacts are the same for the low income, middle income and high income countries on economic growth? Using panel data for high income, low income & middle income countries for the period of 1980–2018, the current study found that all variables effect economic growth significantly where FDI and carbon emission are positive while renewable energy consumption and financial development are negative for economic growth in the whole sample while its differ in the income groups. These studies have shown that these variables are not the same as the economic growth of economic growth and different income groups are not the same, but it changes. In addition, the foundation of this study has a great deal of recommendations for income Group economic decision make-up.

Abstract Global warming and its unavoidable negatives effects on man and the environment have been a key if not the most important issue occupying policy makers in the world at large today. The much talked about green economy nowadays seeks to achieve sustainable economic growth and development without compromising environmental quality. The relationship between environmental degradation and economic growth is largely explained by the environmental Kuznets Curve (EKC) hypothesis. By employing the basic postulation of the baseline EKC framework, this study proposes and tests the existence of a dualistic approach of the EKC hypothesis. Geometry is used to illustrate the proposed dualistic model. Meanwhile, the novel dynamic common correlation effect econometric technique is employed to test the existence of the dualistic EKC within a panel of 109 countries from 1995 to 2016. The outcome from the estimated models shows that, in the global sample, the existence of the dualistic U-shape and N-shape EKC hypothesis is validated. When the sample is split into sub samples based on income levels, the U-shape EKC hypothesis is validated for lower income and high income economies meanwhile, the N-shape dualistic EKC is mostly associated with high income economies.

<p>The aim of this study is to analyze the effect of the US mortgage crisis on macroeconomic indicators by considering classification of countries by income groups. Using the data of World Development Indicators prepared by World Bank, countries are classified in four groups respectively low-income economies, lower-middle-income and upper-middle-income and high-income economies. For these groups of countries the data of macroeconomic indicators such as economic growth, employment, inflation, export, from 2005 to 2015 are examined. Obtained results show that group of high income countries have not just been heavily affected from 2008 crisis, but also facing problem of weak growth and risk of deflation, whereas middle income economies have been affected from declining commod­ity prices. Present conditions are required to initiate proactive fiscal and monetary policies in the world.</p>

Using Data

Income polarization is a pressing issue which is increasingly discussed by academics and policymakers. The present research examines income polarization in Canada’s eight largest Census Metropolitan Areas (CMAs) using data at the census-tract (CT) level between 1971 and 2016. Generally, there are significant decreasing trends in the middle-income population with simultaneously increasing trends in low-income groups. The high-income groups have been relatively stable with fewer significant increasing population trends. Using conventional mapping and cartograms, patterns of the spatial evolution of income inequality are illustrated. Every CMA examined contains an increasing trend of spatial fragmentation at the patch level within each CMA’s landscape mosaic. The results of a spatial autocorrelation analysis at the sub-patch, CT level, exhibit significant spatial clustering of high-income CTs as one process that dominates the increasingly fragmented landscape mosaic.

As mitigating the effects of energy consumption on the environment is a crucial issue for the Asia-Pacific region, this study investigates the energy-environmental Kuznets curve (EEKC) hypothesis among the 19 Asia-Pacific countries. The study also tests the EEKC hypothesis for the low-, middle-, and high-income groups of the region. The panel regression and cointegration models are used for this purpose. Our test results of both models suggest that the EEKC hypothesis holds for the whole Asia-Pacific region. However, the test performed on the three different income groups revealed that the hypothesis only holds for the high-income group. The hypothesis was not apparent for the low- and middle-income groups. This indicates that the transition in the energy consumption along the EEKC is only occurring in the developed countries of the Asia-Pacific region and the developed countries need to support the developing countries to achieve economic growth along the EEKC.

Background: Socioeconomic markers such as income level are associated with cardiovascular disease (CVD). However, the associations between income and utilization of CVD preventive services, such as receipt of lifestyle advice and screening for CVD risk factors in populations with and without established CVD are less well understood. Methods: We used data from the nationally representative Medical Expenditure Panel Survey (2006-2015). We included adults (≥18 years old) and divided the sample population into 2 groups: those with CVD (defined by self-reported and/or ICD9 diagnosis of CVD [coronary artery disease, stroke, heart failure, cardiac dysrhythmias and/or peripheral arterial disease]) and those without CVD. Participant responses were recorded by telephone survey. Additional information on health care utilization was collected from physicians, hospitals, and pharmacies. We categorized participants as high income (400% of federal poverty level [FPL]), middle income (200-400% of FPL), low income (125-200% of FPL) and poor/very low income (<125% of FPL). We used logistic regression to compare likelihood of utilizing or receiving certain CVD risk preventive services among participants in different income groups, adjusting for demographics, comorbidities and other socioeconomic factors. Results: We included 185,081 participants without CVD (representing 194.6 million US adults without CVD, 48% female) and 32,862 participants with CVD (representing 37 million U.S. adults with CVD); 36% of individuals with CVD were in the high income category, 29% were middle income, 16% and 19% were in the low and poor/very low income group, respectively. Compared with high income adults, adults with low and poor/very low income were less likely to have cholesterol levels or blood pressure checked and receive counseling about diet modifications, exercise, or smoking cessation, regardless of CVD status ( Table ). Conclusion: Poor/very low income adults were much less likely to be screened for CVD risk factors or receive counseling for prevention of CVD than high income adults. More work must be done to reduce disparities in access to and utilization of CVD preventive services among adults in different income groups.

The impacts of renewable energy adoption and environmental sustainability ratings on the validity of the environmental Kuznets curve and the pollution haven hypothesis are examined using annual balanced panel data from 64 middle and low-income countries and spanning the 2005 –2014 period. We show that the GDP per capita/CO2 emissions per capita relationship is an inverse S curve for the full sample of low and middle-income countries and for each subsample. The renewable energy/CO2 emissions per capita relationship is an inverse N curve for the full and the middle-income samples, but a V curve for the low-income sample. The foreign direct investment net inflows/CO2 emissions per capita relationship is an N curve for the full and the middle-income samples, and a positive relationship in the low-income subsample. High levels of government environmental sustainability ratings in low-income countries with relatively higher incomes can attract foreign direct investment net inflows while reducing pollution. In contrast, middle-income countries with high environmental sustainability ratings can attract foreign direct investment net inflows only if they allow small increases in pollution.
