Abstract
Social distancing policies have been criticized for their adverse effect on economies. However, we evidence that while they have a short-run adverse effect, they also have a long-run recovery effect on economic growth. Utilizing quarterly gross domestic product (GDP) growth rate data from OECD member states, we find that the medium-term recovery effect of stringent social distancing policies on economic growth is three times higher the short-term adverse effect. We additionally investigate social distancing measures with sub-components of GDP, as well as the conditioning roles of institutional factors.Entities:

Impact of social distancing measures on Gross Domestic Product growth rates
Dependent variable is quarterly Gross Domestic Product growth rate, measured as quarter-on-quarter increase in gross domestic product, in all regressions. Stringency Index measures the stringency of government social distancing policies regarding schools and workplaces closures and bans on local and international movement. Lagged stringency index is one quarter lagged values of stringency index. Stringency Index and lagged stringency index are two main explanatory variables of interest. COVID-19 confirmed cases is new total quarterly confirmed cases of COVID-19 in each country. Gross Domestic Product per capita equals the log of per capita gross domestic product for the year 2019. Trend of GDP growth equals the average of GDP growth rates of years 2018 and 2019. Inflation equals the annual change in prices of consumer goods in each country for the year 2019. Population equals the natural logarithm of total population (latest available figures) of each country. Births per woman is measured as the national average number of births per woman. Expected life in years represents the expected life of an individual at the time of birth. Education counts the number of new enrolments in primary-level educational schools. Rule of law measures the extent of rule following and the chances of crime and violence in a nation. Estimations are made with pooled panel ordinary least squares regression model. Standard errors are clustered at country-level. P-values are given in parenthesis. ***, **,* represent statistical significance at 1%, 5%, and 10% levels, respectively.

| Stringency Index | Extent of government social distancing policies. The index incorporates information from eight indictors including closure of workplace, closure of educational institutions, cancelation of public events, restrictions on gathering size, closure of public transport, stay at home requirements, restrictions on internal movement and restrictions on international travel. Stringency Index is calculated by adding these indicators and rescaling so that it varies from 0 to 100.

| Trust in government | Captures the share of respondents with ‘yes’ answer to the question “In this country, do you have confidence in national government?” Other potential answers are ‘no’ and ‘don't know’.

| Tightness | Tightness-looseness cultural dimension. Higher values represent the cultural tightness where individuals are more likely to follow social norms. | ( |
| Trust | Calculated from the answer to the question “Generally speaking, would you say that most people can be trusted or that you cannot be too careful in dealing with people?” in World Values Surveys. Higher values represent higher trust. | World Values Surveys |
