Abstract

The coronavirus-19 pandemic has become a threat to health and economic conditions, including a threat to transactions in the money market and the model market. The purpose of this study was to determine the magnitude of the effect of Covid-19 cases on Sukuk and the exchange rate; know the magnitude of the effect of exchange rates and bonds on Sukuk, and know the indirect relationship between Covid-19 and Sukuk. The data analysis method in this study uses a two-stage least square model approach, with a sample range from March 2020-November 2021. The results of the analysis conclude that the Covid-19 case influences the decline in the exchange rate, while the Covid-19 case has no effect on Sukuk. Other factors that affect Sukuk are the exchange rate and bonds. The results of the study also concluded that the Covid-19 case indirectly affected Sukuk through the exchange rate. This study contributes to the understanding of Sukuk, which can be influenced by many conditions, both coming from within the capital market itself and from external factors.

Abstract

Pandemic covid-19 presents a policy of tightening the mobility of the population, which directly impacts the reduced mobility of transportation, private transportation, and public transportation. Economic activity also under pressure from the existence of pandemic covid-19, in which economic activity is a source of air pollution for a large part of the country. The purpose of the study to find out the impact of pandemic covid-19 and economic growth on air quality during the pandemic is in 2020. The research method uses a multiple regression approach with a sample count of 80 countries. The results showed that economic growth has no impact on improving air quality and does not prove the environmental Kuznets curve between development and air pollution. In contrast, the increase in cases of covid-19 has the effect of lowering air pollution in each country. This condition occurs because covid restricts the population to activities, which also affects the activities of the company to produce.

Abstract

This study examines the macroeconomic variables exchange rate and BI rate in collaboration with the Coronavirus Disease case against Sukuk. In addition, this study also examines the exchange rate influenced by the BI rate variable and the case of Coronavirus Disease. The data analysis method in this study uses a simultaneous equation model Two-Stage Least Square. This study found that the exchange rate affects the demand for Sukuk while the BI rate does not affect it. But what is surprising is that when the Coronavirus Disease 2019 case occurred, it did not affect the demand for Sukuk. This study also found that the exchange rate is influenced by the BI rate and the case of Coronavirus Disease. The contribution of this research is that when the government cannot intervene in the exchange rate, which can affect the demand for Sukuk, it can be done by intervening in the BI rate.JEL Classification: C30, G12, O10How to Cite:Bawono, A., Rofiuddin, M., Nabila, R., & Anwar, S.
