La evolución mundial y el crecimiento poblacional actual ejerce presiones ecológicas, económicas y sociales sobre los sistemas urbanos provocando mayor vulnerabilidad a sufrir desastres de tipo naturales y antrópicos.

The Corona Virus Disease 2019 (COVID-19) has been a tough test on companies in the global food sector supply chain, exacerbating the realities and deficiencies it presents in developing economies. This situation has been reflected in the firm’s performance (F.P.) due to the lack of business conditions to respond to the current pandemic. However, in some companies, the adverse effects of COVID-19 have been counteracted due to endowment and technological capabilities.

The consumption of renewable energy has become a substitute for fossil fuels to mitigate environmental degradation. However, this substitution of energy raises many questions regarding its possible impact on economic growth. In this context, this research aims to examine the long-term relationship between economic growth and financial development, non-renewable energy, renewable energy, and human capital in 16 Latin American countries.

El objetivo de esta investigación es analizar la relación de cointegración entre exportaciones, crecimiento económico y densidad demográfica con emisiones de CO2 a nivel mundial y por grupos de países. Utilizando datos de panel en 90 países para el periodo 1961-2015. Esta investigación se sustenta con la hipótesis de la Curva Ambiental de Kuznets (1955) y evidencia empírica.

La contaminación sin duda es un fenómeno mundial, que ha causado estragos negativos en el ambiente;además, la demanda de los recursos limitados se va incrementado con el paso del tiempo. En este sentido,el objetivo de la presente investigación es analizar la relación que tienen el consumo de los hogares y la contaminación ambiental. Utilizando datos del World Development Indicators (2010) para 101 países del mundo, durante el periodo 1985-2016. Los países fueron clasificados por regiones de acuerdo al BancoMundial.

Tacit knowledge sharing is an essential intellectual capital for frontline employees in hotel enterprises. While the relationship of knowledge sharing with team culture (TC) and innovative work behavior (IWB) was investigated in the extant literature, little is known about the extent to which tacit knowledge sharing affects TC and IWB. In this regard, the purpose of this study is to investigate the role of tacit knowledge sharing in the relationship between TC and IWB. For this purpose, data were gathered from 360 department managers of Turkish 4–5 star hotels.

In this paper we examined the interaction between greenhouse gas emissions, nuclear energy, coal energy, urban agglomeration, and economic growth in Pakistan by utilizing time series data during 1972–2019. The stationarity of the variables was tested through unit root tests, while the ARDL (autoregressive distributed lag) method with long and short-run estimations was applied to reveal the linkages between variables.

The achievement of the Sustainable Development Goals (SDG) related to the environment requires identifying new sources of environmental degradation. In this research, we examine the impact of the underground economy on polluting gas emissions. This relationship was estimated, including the role of globalization, trade, and market size. Using annual data from the World Bank and the International Monetary Fund, we found that, in the short term, the underground economy had a negative effect on global environmental pollution and a long-term negative impact.

The stylized facts show that natural resource prices are highly volatile. The immediate consequences of such volatility are changes in the labor force’s income distribution and public spending. In this context, this research aims to examine the impact of natural resource rents on inequality, including the role of the shadow economy and the human capital index. We use annual data and second-generation panel data cointegration techniques to correct potential bias caused by slope heterogeneity and cross-section dependence.

The false hope that economic development would lead to a decrease in fossil sources’ energy consumption can be an obstacle to fighting global warming. Is it realistic to expect that more knowledge will lead public policymakers to take more decisive action to mitigate climate change’s adverse effects? This research attempts to answer both premises using data for developed countries with high human capital levels: 27-member countries of the Organization for Economic Cooperation and Development-OECD during 1980–2015.
