Remittances inflow plays a significant role in promoting the economic welfare of a country; it has a multidimensional effect on the economy and links with the carbon emissions. This study examines the possible asymmetric transmissions from remittances to carbon dioxide emissions (CO2) in China using time series data from 1980 to 2014. The Non-linear NARDL method is employed to check the longrun asymmetric relationship between remittances inflow and carbon emissions. The findings show that a positive shock in remittances causes an increase in CO2 emissions, while a negative shock in remittances causes a decrease in CO2 emissions. The results support the existence of an asymmetric cointegrating relationship between remittances and CO2 emissions in both short run and the long run. The NARDL dynamic multiplier graph assumes that positive remittances shocks are highe compared to the negative remittances shocks. It suggests that policymakers in China should consider remittances as a policy instrument especially designing strategies and policies related to sustainable environmental quality in the long run.

Hepatitis B is a globally infectious disease. Mathematical modeling of HBV transmission is an interesting research area. In this paper, we present characteristics of HBV virus transmission in the form of a mathematical model. We analyzed the effect of immigrants in the model to study the effect of immigrants for the host population. We added the following flow parameters: “the transmission between migrated and exposed class” and “the transmission between migrated and acute class.” With these new features, we obtained a compartment model of six differential equations. First, we find the basic threshold quantity Ro and then find the local asymptotic stability of disease-free equilibrium and endemic equilibrium. Furthermore, we find the global stability of the disease-free and endemic equilibria. Previous similar publications have not added the kind of information about the numerical results of the model. In our case, from numerical simulation, a detailed discussion of the parameters and their numerical results is presented. We claim that with these assumptions and by adding the migrated class, the model informs policy for governments, to be aware of the immigrants and subject them to tests about the disease status. Immigrants for short visits and students should be subjected to tests to reduce the number of immigrants with disease.

The study estimates the impacts of rising world food prices on poverty in rural and urban areas of Pakistan. Household income and expenditure data for 2004/2005 is used to estimate compensated and uncompensated price and expenditure elasticities using the linear approximation of the almost ideal demand system. Taking the unexpected component of higher domestic food prices in 2007/2008, own and cross price compensated elasticities are used to derive the changes in the quantity consumed, food expenditure and impacts on poverty assuming the food crisis happened in 2004/2005. The results indicate that poverty increased by 34.8%, severely affecting the urban areas where poverty increased by 44.6% as compared to 32.5% in rural areas. The estimates show that 2.3 million people are unable to reach even one-half of poverty line expenditures while another 13.7 million are just below and 23.9 million are just above the poverty line. In the short run, it is important to ensure food availability to these people. In the long run, the policy environment of subsidizing urban food consumers by keeping wheat prices lower than the international price, needs to be reconsidered to provide the right incentives to increase food availability.JEL classification: C13, D12, D33, Q11, Q18

Purpose The coronavirus (COVID-19) pandemic has had profound economic effects, putting women entrepreneurs at considerable risk of losing income and sales growth as a result. This study aims to examine whether the COVID-19 pandemic is a blessing or a curse for women entrepreneurs in Pakistan’s informal sector. The influence of business type, family support and other socio-economic factors on the sales volume of women’s businesses is examined. Design/methodology/approach Data were collected from 400 women entrepreneurs using a survey questionnaire. Logistic regression was used to investigate the relationships between perceived sales volume and socio-economic as well as demographic factors of women entrepreneurs. Findings Findings for RQ1 revealed that the pandemic was a blessing for cloth and cosmetic entrepreneurs, but a curse for those women selling dairy products. Results for RQ2 showed that age, homeownership, household size, family support and type of business were significant predictors of sales. Furthermore, women entrepreneurs were greatly influenced by their family’s desires and decisions, such that women entrepreneurs who received support from families and relatives reported higher sales than those who did not receive such support. Practical implications The results may assist policymakers in designing supportive programs to encourage women’s informal entrepreneurial activities. Creating entrepreneurial ecosystems may provide support for women entrepreneurs beyond family support. The findings provide a better understanding of women’s business effectiveness during COVID-19 pandemic. It reveals the resilience of women entrepreneurs in the face of cultural, economic and institutional constraints encountered during the pandemic. Originality/value This study is unique because it focuses on the impact of the pandemic at the household level rather than examining broad macroeconomic scenarios. To the best of the authors’ knowledge, this study is the first attempt to explore the informal, home-based business sector of women entrepreneurs in Pakistan during the pandemic.

The tribal belt of the Hindu Kush mountains is famous for its unique culture, ethnography, wild food plants, food systems, and traditional knowledge. People in this region gather wild plants and plant parts using them directly or in traditional cuisine, or sell them in local markets. However, there is a huge lack of documentation of the food system, particularly that related to wild food plants (WFP). In the current study, we focus on the uses and contributions of WFPs in the traditional tribal food system of the Hindu Kush valleys along the Pakistan–Afghanistan border. Ethnobotanical data were gathered through questionnaire surveys of 84 informants, including 69 men and 15 women, belonging to 21 different villages of the chosen area. In tribal societies men and women rarely mix and thus very few women took part in the surveys. We documented 63 WFP species belonging to 34 botanical families, of which 27 were used as vegetables, 24 as fruits, six in different kinds of chutneys (starters), and six as fresh food species. Fruits were the most used part (41%), followed by leaves (24%), aerial parts (24%), seeds (7%), stems (3%), and young inflorescences (1%). The reported uses of Carthamus oxyacantha, Pinus roxburghii seeds, and Marsilea quadrifolia leaves are novel for the gastronomy of Pakistan. The results reveal that WFPs provide a significant contribution to local food systems and play a role in addressing human nutritional needs, which are usually not met through farming practices. The tribal peoples of the Hindu Kush use WFPs for their nutritional value, but also as a cultural practice—an inseparable component of the tribal community’s lifestyle. This important traditional knowledge about the gathering and consumption of WFPs, however, is eroding at an alarming rate among younger generations due to the introduction of fast-food, modernization, and globalization. Therefore, appropriate strategies are imperative not only to safeguard traditional plants and food knowledge and practices, as well as the cultural heritage attached to them, but also to foster food security and thus public healthcare via local wild foods in the region.

Th e main aim of the article is to show the response of the Maximum Residue Limits adopted by importing countries on exports of the selected food commodities from China. Th e study estimates the gravity model using the Ordinary Least Squares, Poisson and the Negative Binomial Regression estimators. According to the results, the Maximum Residue Limits has a trade enhancing eff ect on exports of the selected food commodities from China. Th is trade enhancing impact may be due to the current government policies to put a cut on the food safety issues, to ensure safe food for all and adopting a protectionist policy in terms of the Maximum Residues Limits for the selected commodities.

Islam has encouraged women to participate in entrepreneurial activities for economic prosperity and social growth. Nevertheless, their participation in economic activities is very lesser than men globally. Previously, the field of entrepreneurship has been regarded as a male dominant sector. Entrepreneurship flourishes due to economic, social, ethical, and environmental factors while the practice of Sharia principles works as a catalyst in this process. Women entrepreneurship helps in alleviating poverty and unemployment that leads to socio-economic prosperity in a country. The motivation of starting women businesses varies in different cultures and geographic regions. Women engagements in different business activities can not only empower them socially and financially but can also share the household economic burden with men. Furthermore, it will also help them to make their decisions independently. Their entrepreneurial income can be used for their children’s education, health, and the betterment of society. They can also use the option of partnership within the family for the financial and social network. The challenges faced by these women entrepreneurs can be handled with their family support. This review provides a general overview of concepts, motives, challenges, and the prospects of women entrepreneurship from an Islamic perspective.
