We provide evidence of the impact of the COVID-19 pandemic on racial hate crime in England and Wales. Using various data sources, including unique data collected through Freedom of Information (FOI) requests from UK police forces, a difference-in-difference and event study approaches, we find...

We provide causal evidence of the impact of the Brexit referendum vote on hate crime in the United Kingdom (UK). Using various data sources, including unique data collected from the UK Police Forces by Freedom of Information (FOI) requests, and various estimation methods...

In this paper, we present evidence on empirical connections between crime and education, using various data sources from Britain. A robust finding is that criminal activity is negatively associated with higher levels of education. However, it is essential to ensure that the direction of...

We analyze the illicit drug usage by inhabitants and visitors of European cities. Our statistical analyses are by means of linear mixed models. The data on illicit drug usage of cocaine, ecstasy, amphetamines, methamphetamines, and cannabis are collected through wastewater samples from the inlet...

The Commonwealth of Virginia abolished parole and reformed sentencing for all felony offenders committed on or after January 1, 1995. We examine the impact of this legislation on reported crime rates using different time series approaches. In particular, structural time series models are...

We show that efficient importance sampling for nonlinear non-Gaussian state space models can be implemented by computationally efficient Kalman filter and smoothing methods. The result provides some new insights but it primarily leads to a simple and fast method for efficient importance...
