Purpose The purpose of this paper is to examine the determinants of foreign direct investment (FDI) by focusing on institutional and economic factors among South Asian Association for Regional Cooperation (SAARC), Association of South East Asian Nations (ASEAN) as well as Central Asian countries over the period 2002-2014.Design/methodology/approach The generalized method of moments technique is employed for analyzing the impact of institutional quality on FDI inflow by controlling for the effect of market size, domestic investment and labor force.Findings The authors found large variations in terms of the impact of institutional and economic variables in regards to FDI in the SAARC, Central Asian and ASEAN regions. The results reveal that real GDP, domestic investment and economic freedom index have a positive and significant effect on FDI inflows in the SAARC region, while governance index and labor force have a negative impact on FDI inflows. In Central Asia, the real GDP, domestic investment and governance index are positively associated with FDI inflows, whereas the effect of economic freedom index on FDI is negative as well as insignificant. Apart from the GDP, other variables such as labor force, domestic investment, governance and economic freedom indices influence FDI positively in the ASEAN region. It is worth mentioning here that domestic investment produces positive effect on FDI inflows in all the regions. On the whole, the authors may conclude that institutional factors play an important role in attracting FDI inflows in the ASEAN region as compared to Central Asian and SAARC regions.Originality/value A limited research work is available that could help in identifying the role of institutional and economic factors simultaneously in attracting FDI in the SAARC, Central Asian and ASEAN regions.

The coronavirus disease 2019 (Covid-19) pandemic, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is an international public health crisis with devastating effects. In particular, this pandemic has further exacerbated the burden in tropical and subtropical regions of the world, where dengue fever, caused by dengue virus (DENV), is already endemic to the population. The similar clinical manifestations shared by Covid-19 and dengue fever have raised concerns, especially in dengue-endemic countries with limited resources, leading to diagnostic challenges. In addition, cross-reactivity of the immune responses in these infections is an emerging concern, as pre-existing DENV-antibodies might potentially affect Covid-19 through antibody-dependent enhancement. In this review article, we aimed to raise the issue of Covid-19 and dengue fever misdiagnosis, not only in a clinical setting but also with regards to cross-reactivity between SARS-CoV-2 and DENV antibodies. We also have discussed the potential consequences of overlapping immunological cascades between dengue and Covid-19 on disease severity and vaccine development., (© 2020 John Wiley & Sons Ltd.)
