Crowding-out effects of tobacco consumption refers to the situation in which tobacco consumption reduces a household's spending on other commodities. In this paper, we test for the crowding-out effects of recreational tobacco consumption on food expenditures among on-reserve Indigenous communities in Canada.
We use data from household expenditure surveys (N=469) to investigate tobacco consumption behaviour of on-reserve households of six First Nation communities in Canada. Using conditional Engel curves, we estimate the crowding-out effects of spending on tobacco on budget share of other expenditure categories with a focus on food expenditures.
Our analysis showed that crowding-out effects of consuming tobacco on consumption of goods and services are minimal with an estimated impact of -0.00004 on the budget share of food expenditures in the remaining budget excess of expenditures on tobacco. While crowding-out effects are not statistically significant in general, the budget share of store-bought food expenditures is significantly lower (i.e. 5%) among tobacco consumer households.
This study sheds new light on some of the indirect impacts of recreational tobacco use and Indigenous food insecurity in Canada. This study is the first attempt to test for crowding-out effects of tobacco consumption among Indigenous populations in Canada. Our findings are important and highlight areas for substantial improvements in health and well-being outcomes given the alarming rates of food insecurity experienced by Indigenous communities in Canada.
烟草消费的挤出效应是指烟草消费减少家庭在其他商品上支出的情况。本文检验了加拿大保留地原住民社区娱乐性烟草消费对食品支出的挤出效应。
我们使用来自家庭支出调查的数据（N=469），调查了加拿大六个原住民社区保留地家庭的烟草消费行为。通过条件恩格尔曲线，我们估计了支出在烟草上对其他支出类别的预算份额的挤出效应，重点关注食品支出。
我们的分析表明，烟草消费对商品和服务消费的挤出效应很小，估计对烟草支出剩余预算中食品支出预算份额的影响为-0.00004。虽然挤出效应总体上不具有统计学意义，但烟草消费者家庭的商店购买食品支出预算份额明显较低（即 5%）。
本研究为加拿大娱乐性烟草使用和原住民食品不安全的一些间接影响提供了新的视角。这是首次尝试在加拿大的原住民人群中检验烟草消费的挤出效应。鉴于加拿大原住民社区面临的令人震惊的粮食不安全率，我们的发现很重要，并强调了在健康和福祉方面需要大幅改善的领域。
