The purpose of this study is to determine the leading indicators of the COVID-19 pandemic in Australia using daily data from 31 December 2019 to 14 October 2020. This study applies the signal extraction technique, which is usually used to predict a financial crisis to examine 30 COVID-19...

We assess whether the COVID-19 vaccine induces COVID-19 risky behavior (e.g., going to bars and restaurants) and thus reduces vaccine efficacy. A key empirical challenge is the endogeneity bias when comparing risk-taking by vaccination status since people choose whether to get vaccinated. To...

We investigate the impact on work absence of a massive reduction in paid sick leave benefits. We exploit a policy change that only affected public sector workers in Spain and compare changes in the number and length of spells they take relative to unaffected private sector workers. Our results...

In this paper, we study the impact of the COVID-19 vaccination on the COVID-19 cases and deaths by applying the instrumental variable estimator to spatial regression models and data of US counties for the period of January 01, 2021, to November 15, 2021. We document robust evidence of...

A long-standing economic question is how protection against harm from insurance or other harm reducing interventions leads to potentially offsetting behavior changes (ex-ante moral hazard). Immunization is a type of insurance, as individuals incur an upfront cost when they get vaccinated, but it...

Using traffic data from Taiwan for 2020, we quantify how the COVID-19 outbreak affected demand for public and private transportation. Despite there being no governmental restrictions, substantial shifts in travel modes were observed. During the peak of the pandemic in Taiwan within the study...

In this study, we provide the first estimates of the effect of COVID-19 (COVID-19 legal restrictions) on catastrophic medical expenditure and forgone medical care in Africa. Data for this study were drawn from the 2018/19 Nigeria General Household Survey (NGHS) panel and the 2020/21 Nigeria...

This study first documents robust evidence that the COVID-19 death ratio and infection ratio are positively associated with income inequality, higher non-White/White residential segregation index, and higher percentage of adults aged 65 and below without health insurance. Second, death and...

This paper combines pre-pandemic face-to-face survey data with follow up phone surveys collected in April-May 2020 to quantify the overall and differential impacts of COVID-19 on household food security, labor market participation and local food prices in Nigeria. We exploit spatial variation in...
