The use of static-demand systems in empirical analysis assumes that consumers adjust immediately to a new long-run equilibrium path when a shock is encountered. However, adjustment is not always instantaneous. This paper utilizes an Error-Corrected Linear Approximate Almost Ideal Demand System (EC-LAAIDS) model to analyze the import demand for meat and seafood in Indonesia from 1976 to 2020 using annual data. The study found that the theoretical restrictions of homogeneity and symmetry held in the EC-LAAIDS model but did not in the long-run model. The adjustment parameter reveals that imported mutton had the slowest adjustment to long-run equilibrium, while all other meats and seafood had a moderate adjustment speed. The study calculated income elasticities for both the short- and long-run revealing that imported beef was a luxury good in the short-run and most responsive to changes in income. In the short-run, imported poultry was the least responsive to changes in income. In the long-run, all imported meats were found to be luxuries except for imported seafood and beef. Uncompensated price elasticity of demand reveals that in the short-run all imported items had inelastic demand except for imported beef which had elastic demand. In the long-run, however, imported beef and pork had elastic demand, while all other items were inelastic. Compensated cross-price elasticities found that mostly substitution relationships existed among pairs of imported commodities. Finally, a few policy suggestions were discussed, such as production subsidies to producers., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2023 The Author(s).)

This study revisits the tourism-led growth discourse and differs from the existing literature to examine if information and communications technology (ICT) moderates the relationship between tourism and economic growth in East Asia and the Pacific. Using data on 33 selected countries, the study deploys the Driscoll and Kraay (1998) [1] panel spatial correlation consistent (PSCC) approach, Machado and Santos Silva (2019) [2] method of moments quantile regression (MMQR) and Arellano and Bond (1991) [3] generalized method of moments (GMM) technique. Using a composite ICT index on four indicators ((mobile phones, fixed telephones, fixed broadband, and secured internet servers) derived from the Principal Component Analysis (PCA), the results which are mostly consistent across the three estimation methods reveal, among others, that (1) ICT moderates the tourism-growth path and the effect is positive and statistically significant; (2) the moderation effect is consistently positive across all quantiles of Q 0.25 , Q 0.50 and Q 0.75 ; (3) the results are sustained when omitted variables (growth enablers) - institutions, R&D, and human capital - are accounted for. Policy recommendations are discussed., Competing Interests: The authors declare no conflict of interest., (© 2023 The Author.)

This study brings novelty to the tourism literature by re-examining the role of exchange rate in the tourism-growth nexus. It differs from previous tourism-led growth narrative to probe whether tourism exerts a positive effect on economic growth when the exchange rate is accounted for. Using a moderation modelling framework, instrumental variables general method of moments (IV-GMM) and quantile regression techniques in addition to real per capita GDP, tourism receipts and exchange rate, the study engages data on 44 Asian countries from 2010 to 2019. Results from the IV-GMM show that: (1) tourism exerts a positive effect on growth; (2) exchange rate depreciation hampers growth; (3) the interaction effect is positive but statistically not significant; and (4) results from EAP and SA samples are mixed. For the most part, constructive evidence from the quantile regression techniques reveals that the impact of tourism and exchange is significant at lower quantiles of 0.25 and 0.50 while the interaction effect is negative and statistically significant only for the SA sample. These are new contributions to the literature and policy recommendations are discussed., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2022 Adeleye et al.

This study exclusively contributes to the health-environment discourse by using mortality rates, carbon emissions (proxy for environmental degradation), renewable energy and real per capita income to investigate these intrinsic relationships. This study uses an unbalanced sample of 47 Sub-Saharan African countries from 2005-2019 to reveal that: (1) both carbon emissions and renewable energy are associated with higher mortality rates; (2) real per capita income is associated with reducing mortality rates; (3) per capita income attenuates the effect of renewable energy on mortality rates, (4) persistency in mortalities exist; and (5) the health-environment-energy-income dynamics differ across income groups. Additionally, this study submits that the interaction of renewable energy and real per capita income dampens the positive effect of renewable energy on mortality rates and supports the argument that income levels lessen the extent of mortalities. Besides, these results vividly show that real per capita income reduces the devastating effect of renewable energy on infant and under-5 mortality rates from 0.942% to 0.09%, 2.42% to 0.55%, 1.04% to 0.09% and 2.8% to 0.64% for high and middle-income countries, respectively. This is a novel and significant contribution to the health-environment literature. Hence, real per capita income is a crucial determinant of mortality rate.

The study examines the nexus between household ICT utilization and food security in Nigeria, which supports goal 2 of the 2030 Sustainable Development Goals (SDGs) that aims to " end hunger, achieve food security, improved nutrition, and promote sustainable agriculture. " The study employs the logit regression to wave 4 of Living Standard Measurement Integrated Survey on Agriculture (LSMS) data for the empirical analysis. Based on the analysis, the study finds that for male household, ICT utilization has a statistically significant and positive nexus with food security. In contrast, for the female households, an insignificant and, however, negative nexus is observed with food security in Nigeria. Furthermore, the findings show that for male household users, a 1 percent increase in male household ICT utilization spurs about 0.68 percent increase in food security in Nigeria. The findings imply that among the male and female household ICT users, the male household ICT utilization is significantly contributes to food security in Nigeria. The study recommends that relevant stakeholders take strategic measures to ensure that the potentials of household ICTs be fully maximized to contribute to food security in the nearest future as confirmed by studies in other regions., Competing Interests: The authors declare that there are no conflicts of interest., (Copyright © 2021 Jeremiah O.

This study contributes towards the realization of Sustainable Development Goal (SDG) 13 which aims "take urgent action to combat climate change and its impacts" by investigating the role of per capita income in moderating the impact of energy use on carbon emissions. Using data from 28 selected African countries covering 1990 to 2019 and deploying the FGLS, PCSE, and MM-QR techniques, findings reveal, among others, that: at the 1% significance level, a percentage change in energy use leads to between 0.60% and 0.70% increase in carbon emissions, on average, ceteris paribus. Correspondingly, income shows to be a positive driver of emissions contributing between 0.87% and 0.84% percentage increase, on average, ceteris paribus. Also, per capita income attenuates the impact of energy use on emissions by between -0.27% and -0.23%, on average, ceteris paribus. However, significant heterogeneities occur across the sub-regions. Specifically, Southern Africa shows the largest energy contributor to emissions 1.65% while Central Africa contributes the most to aggravating emissions by 1.87% through increase in per capita income. West Africa shows the largest moderation effect at -0.56%. Across the quartiles, the effects of energy use and per capita are positive. Given these, we submit that the strong correlation between energy usage and per capita income (i.e. economic growth) poses a dilemma for African economies in their drive for growth. Leaving room for trade-offs. Perhaps, the lesson is that as African countries seek for more development without contributing to carbon emissions, governments should invest more in renewable energy., Competing Interests: The authors have declared that no competing interests exist.

This study revisits the 2030 United Nations Sustainable Development Goal (SDG) 2 which aims to "end hunger, achieve food security, improve nutrition and promote sustainable agriculture" by highlighting the impact of environmental degradation (proxied by carbon emissions) and non-renewable energy on agro-productivity in Nigeria. Using annual time series data from 1980 to 2018, the study engages the Johansen cointegration and impulse response functions (IRFs) techniques within the vector autoregressive (VAR) framework. Evidence reveals that carbon emissions significantly reduce agro-productivity by 0.23% while non-renewable energy boosts agro-productivity by 5.38%, on average, ceteris paribus. Other results reveal that domestic credit, rural population and arable land exert asymmetric effects. These outcomes are consistent and align with a priori expectations. Policy recommendations are discussed., (© 2021. The Author(s).)

To " end poverty in all its forms everywhere " and " reduce inequality within and among countries ", this study aligns with the 2030 Sustainable Development Goals 1 and 10. It uniquely contributes to the growth-poverty-inequality discourse by using per capita consumption expenditure growth (poverty), Gini index (inequality) and GDP growth (economic growth). It is a comparative analysis of 58 Sub-Saharan Africa (SSA) and Latin American (LAC) countries (from 2000 to 2015) to determine whether economic growth reduces the incidence of poverty and if its interaction with income inequality enhances or alters its impact on poverty. Consistent findings from a multi-analytical approach using pooled ordinary least squares, fixed effects and system GMM reveal that: (1) economic growth exhibit poverty-reduction properties; (2) the growth rate of inequality intensifies poverty, (3) inequality aggravates the impact of growth on poverty, and (4) the growth-poverty-inequality trilemma differs across income groups and regional samples. Furthermore, this study submits that the interaction of income inequality dampens the positive impact of economic growth on the incidence of poverty and supports the argument that the extent of inequality lessens the effect of inclusiveness. Hence, income inequality is a crucial determinant of poverty. Policy implications are discussed., Competing Interests: The authors declare no conflict of interest., (© 2020 The Author(s).)
