In this paper, we use daily administrative data from January 25, 2020 to December 31, examine the relationship between job losses and Malaysian lockdown measures. The Auto Regressive Distributed Lag (ARDL) approach is used estimate both long-run short-run models. results of Bounds F-test for cointegration reveal that there a link government measures (both linear non-linear). positive associatio...
Abstract This study aims at examining the extent to which exchange rate impacts on balance of payments in Algeria (BoP) during period 1980-2019, using Auto-Regressive Distributed Lag (ARDL) model and Error Correction Model (ECM). approach tests presence a long-run relationship between variables.A set relevant variables, addition rate, were used include real interest oil price, GDP per capita, G...
T he main aim of this study is to investigate the impacts of population total, gross domestic product per capita, urbanization rate and energy use on carbon emissions in Nigeria for a period of 1981-2015 using autoregressive distributed lag approach to co-integration (ARDL). The empirical results revealed evidence of a long run relationship among the variables. The generalized ridge ...
World population is expected to reach 9.2 × 10(9) people by 2050. Feeding them will require a boost in crop productivity using innovative approaches. Current agricultural production is very dependent on large amounts of inputs and water availability is a major limiting factor. In addition, the loss of genetic diversity and the threat of climate change make a change of paradigm in plant breeding...
ongoing climate change has been a major global challenge since the 1880s. sequestration of carbon(c) in rangelands ecosystems could provide a net carbon sink to offset increases in atmospheric c in global scale. this research is aimed at estimating the above-ground biomass carbon sequestration potential in iran. for this purpose, total rangelands area and productivity data were extracted from t...
The nexus between foreign direct investment and economic growth has long been among the most debated issues in macroeconomics. Some studies find a positive link two factors, but others no evidence. This current research fills gap by analysing causal Indonesia for period 1970-2018. as developing country is one of largest recipients FDI flow; hence study on impact very much important. employs con...
The tropics, sadly, continues to be a belt of poverty. The countries of the tropics all have low or middling incomes, with a few tiny or natural-resource-rich exceptions, and few of the poorest countries are outside of the tropics. The causes of tropical poverty are surely complex, involving initial endowments (Diamond), history, especially colonization, and geographical isolation (Gallup and S...
The introduction of science and technology into agriculture over the past two centuries has markedly increased agricultural productivity and decreased its labor-intensiveness. Chemical fertilization, mechanization, plant breeding and molecular genetic modification (GM) have contributed to unparalleled productivity increases. Future increases are far from assured because of underinvestment in ag...
Background: We aimed to investigate the relationship between air pollution and Infant mortality rate (IMR) during nearly ten years in Tehran, Iran.
 Methods: This study is a retrospective cohort case using time series analysis. Air monitoring data period (2009-2018) were collected from information of 23 Quality Control Centers different areas Tehran. For this purpose, daily measures PM10, ...
One major key elements of climate change is rainfall which contributes strongly to agricultural productivity. In Nigeria, the production most food crops through rain-fed especially rice production. Rice national interest and security concern as it forms a part an average Nigerian diet country depends heavily on importation meet citizens’ demand. Also, low yield has been recorded in local this a...
