ABSTRACT:  This study is conducted to estimate the impact of the increase in regular and specific excise rates structure simplification on cigar's consumption through its price. Using data in 2015 and applying random effect model for unbalanced panel data on Sigaret Kretek Mesin-type and Sigaret Kretek Tangan-type of the cigar, this study compares the impact of price increases due to both specific excise rate structure simplification and regular increase on the excise rate in cigar’s consumption. The results indicate that increase in the specific excise rate structure simplification has a lower impact on raising cigar’s prices than regular excise rate increases. Furthermore, the impact of price increases due to the specific excise rate structure simplification is greater in reducing cigar’s consumption than the price increases due to regular excise rate increases. In addition, it is found that the average price of Sigaret Kretek Mesin-type is lower and has an average consumption that is much higher than Sigaret Kretek Tangan-type. Overall, this result suggests that the specific excise rate structure simplification's policy should be continued in order to reduce cigar's consumption.Keywords: specific excise rate structure simplification, cigar’s consumption, random effects modelABSTRAK:  Penelitian ini dilakukan untuk mengetahui pengaruh kenaikan tarif cukai biasa maupun spesifik terhadap konsumsi rokok melalui harga jual ecerannya. Rokok yang digunakan adalah rokok jenis Sigaret Kretek Mesin (SKM) dan Sigaret Kretek Tangan (SKT). Dengan menggunakan data tahun 2015 dan menerapkan random effect pada unbalanced panel data, penelitian ini membandingkan pengaruh kenaikan harga jual eceran akibat penyederhanaan struktur tarif cukai spesifik dan kenaikan tarif cukai biasa terhadap konsumsi rokok. Hasil penelitian menunjukkan bahwa penyederhanaan struktur tarif cukai spesifik berpengaruh lebih rendah terhadap kenaikan harga jual eceran rokok dibandingkan dengan akibat kenaikan tarif biasa. Lebih lanjut, pengaruh kenaikan harga jual eceran akibat penyederhanaan struktur tarif cukai spesifik lebih besar dalam mengurangi konsumsi rokok dibandingkan kenaikan harga jual eceran akibat kenaikan tarif cukai biasa. Selain itu ditemukan bahwa harga jual eceran rata-rata rokok jenis Sigaret Kretek Mesin (SKM) lebih rendah dan mempunyai rata-rata konsumsi yang jauh lebih tinggi dibandingkan rokok jenis Sigaret Kretek Tangan (SKT). Secara menyeluruh, temuan ini menyarankan agar kebijakan penyederhanaan struktur tarif cukai perlu dilanjutkan karena efektif untuk mengurangi konsumsi rokok. Kata kunci: Penyederhanaan struktur tarif cukai spesifik, konsumsi rokok, random effects model.

Using unbalanced panel data from the small and medium enterprise surveys in 2005, 2007, 2009, 2011, 2013, and 2015, this chapter investigates factors associated with informality in Vietnam. We assume that household businesses, especially the top tier firms, become formal either because they perceive benefits of formalization such as an increase in the household performance, or because they want to escape bribes and harassment. Using the random effects model with controlling for the pre-formalization trends, our results show that productive household businesses stay informal because net costs from tax payment may surpass net benefits from formalization. Moreover, government controls do not promote formalization, especially among the ‘upper’ tiers of informal households. Our findings raise suspicions of collusion corruption between informal households in top tiers and officials. Future steps could be qualitative and quantitative studies to investigate collusion corruption as a determinant of informality in developing countries.

AbstractThere is a debate in Argentina about the effectiveness of mandatory lockdown measures in containing COVID-19 that lasts five months making it one of the longest in the World. The population effort to comply the lockdown has been decreasing over time given the economic and social costs that it entails. We contributes by analyzing the Argentinian case through information of mobility and contagion given answers to recurrent questions on these topics. This paper aims to fill the gap in the literature by assessing the effects of lockdown measures and the regional relaxation on the numbers of rate of new infections. We also respond to issues of internal political discussion on regional contagion and the effect of marches and unexpected crowd events. We use pool, fixed and random effects panel data modeling and Granger causality tests identifying relations between mobility and contagion. Our results show that lockdown in Argentina has been effective in reducing the mobility but not in way that reduces the rate of contagion. Strict lockdown seems to be effective in short periods of time and by extend it without complementary measures loss effectiveness. Contagion rate seems to be discretely displaced in time and resurging amidst slowly increasing in mobility.
