This thesis investigates if the announcement of lockdown had a significant impact on stock market return in Denmark. The research approach used is quantitative and deductive and the sample consists of ​​daily adjusted close prices of stock from the 20 largest listed companies in Denmark, according to market capitalization rate. The time period studied is 28th of February 2020 till 27th of March 2020. Lockdown's effect on stock market return is studied using a Difference-in-Difference model, where daily adjusted close prices of stocks from the 20 largest companies in Sweden are used as a control group.  The COVID-19 pandemic has for the past two years had a huge impact on societies globally. At the beginning of the COVID-19 outbreak, to try and stop the spread of the virus, governments around the world implemented lockdowns of varying degrees. Denmark was one of the first countries to implement lockdown. However, the culturally and market similar Sweden, opted for a different approach and did not implement a lockdown at all. It is therefore of interest to investigate whether lockdown announcements had a measurable impact on stock returns at the beginning of the COVID-19 outbreak. Previous research conducted by Vasileiou (2020), Baker (2020), Ichev and Marnič (2018), Hassing Nielsen & Lindvall (2021) and Ashraf (2020) on the subject have found that COVID-19 generally contributed to market uncertainty. This uncertainty in turn affected the stock market significantly, both positively and negatively. The major findings of this thesis suggest that the lockdown implemented in Denmark had no significant effect on stock returns during the investigated sample period.

The COVID-19 pandemic has brought about several restrictions throughout society which has limited people's outdoor activities and forced individuals to stay home. These circumstances have possibly had an impact on the prevalence of domestic violence and other types of assault. This paper uses police crime data from the first six months of 2020 to analyse if any changes in domestic violence can be attributed to the implementation of COVID-19 restrictions in Sweden. Using the LUPP method, developed by The Swedish Council for Crime Prevention (BRÅ), this paper investigates weekly changes in crime compared to the same period in 2019 while additionally studying the prevalence of different types of relationships between the victim and offender. Results indicate that partner violence for men has doubled in relation to all assault crimes, and that partner violence for women has also increased substantially, accounting for 46 % of total assault crimes in the observed period. Abuse by family members, other acquaintances, and unknown persons have seemingly gone down in 2020, compared to the same period in 2019. A concluding regression analysis reveals weak to moderate correlations between changes in domestic violence- and non-domestic violence crimes and COVID-19 restrictions, even when changes in seasonality is accounted for. While the increase in domestic violence crimes does not directly coincide with the emergence of COVID-19, results indicate that the implemented restrictions have played an important role in maintaining heightened levels throughout the observed period. Future research is advised to continue testing for correlations to COVID-19 restrictions, while also considering other variables which could be related to domestic violence, such as increased alcohol consumption at home, family isolation, and economic stress.
