“…More recent papers, appearing after the first version of this paper was completed, document bunching of small firms at the VAT registration threshold in Finland (Harju, Matikka, and Rauhanen, 2016), as well as lack of bunching in response to the VAT threshold in Armenia (Asatryan and Peichl, 2016). 14 In particular, Harju, Matikka, and Rauhanen (2016) provide strong evidence of bunching below the VAT threshold in Finland, and argue that compliance costs are the main driver. 15 However, neither of these papers studies the determinants of voluntary registration in detail, nor do they develop a theoretical framework specific to the VAT.…”
