Alcohol consumption in the G7 countries (1960-2021). Permanent versus transitory shocks.

Area of Science:

• Economics
• Econometrics
• Public Health

Background:

• Understanding long-term trends in alcohol consumption is crucial for public health and economic policy.
• Previous studies often focused on short-term fluctuations, neglecting the persistence of consumption levels.

Purpose of the Study:

• To analyze the persistence of alcohol consumption levels in Group of Seven (G7) countries from 1960 to 2021.
• To investigate the impact of external shocks on alcohol consumption patterns.
• To identify countries with significant trends or mean reversion in alcohol intake.

Main Methods:

• Utilized fractional integration techniques to assess the degree of persistence in alcohol consumption time series.
• Analyzed annual sales of pure alcohol per capita (aged 15+) for G7 nations.
• Examined time trends and external shock influences on consumption data.

Main Results:

• Most G7 countries exhibit persistent alcohol consumption patterns (long memory).
• Japan is the only country showing clear evidence of reversion to the mean.
• France displays a significant negative trend, indicating a continuous decrease in alcohol consumption.
• Time trends for other G7 countries were found to be statistically insignificant.

Conclusions:

• Alcohol consumption persistence varies significantly across G7 nations.
• Policy interventions may need to consider the long-term memory properties of consumption patterns.
• Specific country-level analyses, like France's decreasing trend and Japan's mean reversion, offer distinct insights for targeted policies.
