Final answer:
The trend of more women entering the workforce results in larger family incomes and reflects wider economic transformations from agrarian to urban consumer economies, affecting labor supply and consumption patterns.
Step-by-step explanation:
Marketers are interested in knowing the trend of women entering the workforce because this may result in larger family income. The participation of women in the workforce has significantly increased from 18% in 1900 to nearly half by 2017. This shift reflects broader social and economic trends, such as the move from agrarian economies to urban societies with consumer economies, where there is a high standard of living and smaller family sizes. As women enter the workforce, they contribute to the growth of family income, changing consumption patterns and creating new market opportunities for businesses to explore.
Countries that progress towards a consumer economy see a shift in employment patterns, with a greater percentage of women participating in the paid labor force. This does not necessarily lead to long-term changes in unemployment rates, but it does influence the labor supply and could affect the natural rate of unemployment. An increased labor supply, as seen with higher female participation, can also impact the dependency ratio, with implications for social security systems when considering the proportion of the retired population in relation to the working-age population.
