Blinded by worries: sin taxes and demand for temptation under financial worries

Abstract

Imposing “sin” taxes has been the preferred way governments tried to discourage the over-consumption of temptation goods for decades. However numerous evidence shows that consumers exhibit behavioral biases which can affect their reaction to taxes. This paper investigates a potential bias and how it affects demand for temptation: financial worries associated with poverty have been shown to shift attention towards pressing needs, often at the expense of forward-looking decisions. In an online experiment with UK participants, we randomly induce financial worries and ask participants to allocate a budget between basic necessities and temptation goods in an experimental market. We randomly impose “taxes” on temptation by increasing its price. We find that, in the absence of any tax, inducing financial worries lowers demand for temptation, effect stronger for lower-income participants. However, when financial concerns are salient, increasing the tax does not lower demand among lower-income participants. While financial worries might protect against over-consumption of temptation in the absence of tax changes, they also might hurt the poor the most when additional taxes are introduced.

Resource constraints lead to biased attention but decrease unethical behavior

“…Second, a notable limitation of the current work concerns the lack of a measure that can directly assess to what extent people in the scarcity condition actually experience a scarcity mindset. The between-subjects manipulation used here has, however, previously provided strong construct validity (Roux, 2015, Burlacu et al 2021) and appeared to change behavior between participants in our study; yet it should still be addressed in future research. Third, the size of the AOIs might limit our ability to nd effects on participants' tendency to use diagnostic information to increase accuracy in the dots task.…”

Analysing the behavioural, psychological, and demographic determinants of financial decision making of household investors

“…IMP leads to risky financial decisions such as over-spending and over indebtedness [ 70 ] as emotions have overpowered rationality either to obtain immediate sense gratification, alignment with the herd behaviour or to engage in self-indulgence. Interestingly, IMP among low-income groups have recurrently proved to be higher in relation to spending on junk food [ 71 ]. Also, we assert that IMP can downplay the positive effects of FC on FDM and hence weaken the relationship.…”

“…Moreover, the regressive nature of the so-called sin taxes leads to a heavier tax burden for the poor, as people with lower incomes tend to smoke and consume alcohol more than people with higher incomes. Sin taxes hurt poor consumers more (Burlacu et al , 2021; Lyon and Schwab, 1995). Several studies have also compared tax rates and types of tax instruments for the wine sector worldwide.…”
