    Modified tobacco products: are they safer?
    (University of Minnesota Transdisciplinary Tobacco Use Research Center, 2004-06-03) Hatsukami, Dorothy K.
    To assess whether switching to modified tobacco products reduces the amount of tobacco-specific carcinogens in the body, scientists at the University of Minnesota measured carcinogen uptake in smokers who were using either a “reduced exposure” tobacco product (Swedish snuff or the Omni cigarette)or medicinal nicotine. Those using medicinal nicotine had greater reductions. Reductions of carcinogen uptake from modified cigarettes was modest at best.

    Reducing cigarette smoking: Research summary Does it reduce cancer risk?
    (University of Minnesota Transdisciplinary Tobacco Use Research Center, 2004-05-12) University of Minnesota
    To assess whether cutting back on cigarettes reduces the amount of tobacco-specific carcinogens in the body, scientists at the University of Minnesota measured the level of carcinogen uptake in smokers who were reducing their cigarette consumption over 26 weeks. Overall reductions in carcinogen levels were seen, but the levels were modest and were proportionally less than the amount of cigarettes reduced per day.

    Three Essays in Development Economics
    (2021-08) Rahman, Khandker Wahedur
    In spite of tremendous progress in income generation, school enrollment, and agricultural production, developing economies face significant challenges to enhance welfare for their populaces. Although international migration has increased income, there are unknown effects of migration that may have various implications. Agricultural production has increased, but farmer productivity remains sub-optimal due to information and credit constraints. Though more students are enrolling, schools are demonstrating poor productivity as students have low levels of learning. Understanding the impacts of migration, optimizing farmer productivity and increasing their income, and improving school productivity are critical issues to be explored to formulate effective policies for facilitating egalitarian economic development. I explore these issues in my research through empirical microeconomics and impact evaluation.
