Measuring the effects of tax rules and social policy is a tricky business, requiring a creative combination of science, craft and art. If done well, it produces both truth and beauty. The research on the empirical analysis of tax rules and social policy focuses on the effects and impact of government policy. Empirical research may, for example, determine the effects of changes in the social security system and old age pension schemes for several socio-economic groups, and the economic aspects of tax reforms. However, empirical findings may (not) be in line with the expectations of policy makers. Research should therefore examine tax policy and social rules critically. My inspiration is to motivate others – researchers, policy makers, students – to apply empirical work themselves.

I affirm my commitment to recognizing, addressing and eradicating all forms of racism and ethnic oppression. I focus on engaging and collaborating in teaching, support and scholarship that challenge oppressive and unjust forces. I work to reduce racial injustices both within the academy and the broader community. I am in the pursuit to end racial and ethnic bias and to empower our students towards this collective goal. I acknowledge that regardless of one’s own race or ethnicity, individuals are at various points along an anti-racist journey. I also understand that bias can be unconscious or unintentional and that racism is the combination of social and institutional power plus racial prejudice. Identifying these two specific forms of oppression and disparate outcomes do not automatically mean that those involved intended negative impact and having these conversations require courage, respect and compassion, and may not always be or seek to be comfortable. However, I will purposefully strive to identify, discuss and challenge issues of race, color, ethnicity and the impact(s) they have on students, faculty, and staff members.
Via online communication and social media platforms, it seems hard to discuss complex issues such as racism. These platforms are rife with tone-deafness, misunderstandings, personal attacks, and lack of nuance.
