Child Penalty and Premium in Indonesian Couples’ Labour Outcomes

For decades, economists have tracked a persistent pattern in the way families and work intersect: when a child is born, the mother's career often takes a sharp turn downward, while the father's career frequently continues on, or even gains momentum. This phenomenon, known as the "child penalty," describes the long-term drop in a mother's earnings and employment prospects that follows the arrival of her first child. In wealthier nations, where paid parental leave and subsidized childcare are common, this penalty is well-documented but often mitigated by institutional support. However, in developing countries, where social safety nets are thinner and informal work is the norm, the story is less clear. Does the same penalty exist when a mother has no formal job to return to? Does the father's role change in the same way? Understanding this dynamic is crucial because it reveals how deeply gender roles are woven into the economic fabric of a society, shaping not just individual lives but the broader trajectory of national development.

A new study by Ariska Nur Fajar Rini, a researcher at the Australian National University and Universitas Diponegoro, dives into this question using the specific context of Indonesia. By analyzing decades of data from the Indonesia Family Life Survey, which tracks thousands of households over time, Rini set out to map exactly how the arrival of a first child reshapes the work lives of Indonesian mothers and fathers. The research employs a method that allows them to compare parents to people who have not yet had children, effectively creating a "what if" scenario to see what would have happened to the parents if they had remained childless. This approach helps isolate the specific impact of the baby from other life changes, such as aging or general economic shifts.

The results paint a picture of a stark divide between mothers and fathers, but with a surprising twist in the timing of the impact. For Indonesian mothers, the negative effects of childbirth do not hit immediately in the year the baby is born. Instead, there is a delay. The data shows that mothers maintain their work status for the first year, but starting in the second year after the birth, their labor force participation begins to drop significantly. By the second year, a mother's chance of being employed falls by about 6 percentage points compared to her pre-birth status. This decline is not just about leaving work entirely; it is also about a shift in the type of work. Mothers are increasingly likely to lose their formal jobs—those with contracts and legal protections—and move into informal, less secure work, or stop working altogether. The financial toll is severe: for those who remain employed, their earnings drop by roughly 50 percent, and for those who leave the workforce, the loss is even more profound. These effects are not fleeting; they persist for at least seven years, creating a long-term gap in earnings that is difficult to close.

In contrast, the story for fathers is one of quiet stability and gradual, modest improvement. The study finds that becoming a father does not cause a sudden drop in work or income. Instead, fathers show a slow, steady increase in their likelihood of holding formal employment and earning more, though these gains are small and take time to materialize. This suggests that within Indonesian households, the arrival of a child reinforces a traditional division of labor: the mother absorbs the immediate burden of caregiving, often at the cost of her career, while the father's role as the primary breadwinner is subtly strengthened.

However, the location of the family matters immensely, revealing two different realities within the same country. In urban areas, where jobs are often more rigid and childcare is expensive or scarce, the penalty for mothers is delayed but then becomes severe. Urban mothers often stay in their formal jobs for the first year, perhaps supported by maternity leave policies, but as the child grows, the inflexibility of city jobs and the lack of affordable childcare force them out. Their earnings plummet, and they struggle to return to the formal sector. In rural areas, the pattern is different. Rural mothers face a quicker initial drop in employment, likely because their work is often tied to family farms or small businesses that do not offer formal protections. Yet, because rural work is more flexible and extended families are often nearby to help with childcare, these mothers are able to return to work sooner than their urban counterparts. While rural fathers also see a boost in formal employment and earnings over time, the rural environment allows mothers to stabilize their work lives more effectively than the urban environment does.

The study also challenges a common assumption in economic research: that comparing parents to childless couples is the best way to measure these effects. When the researchers compared mothers to women who never had children, the penalty appeared even larger and more immediate, suggesting that the choice to remain childless is linked to different career trajectories that make them a poor comparison group. By focusing on parents who have not yet had a child as the comparison group, the study provides a clearer, more accurate picture of the specific shock that a new baby brings to a household.

Ultimately, the research highlights that the "child penalty" in Indonesia is not a single event but a complex process shaped by geography, job type, and family support. It shows that while Indonesian women have made strides in education, the structural realities of the labor market and the expectations of family life still conspire to pull them out of the workforce or into lower-paying roles once they become mothers. The findings suggest that policies aimed at helping working parents must be tailored to these local realities: urban mothers need affordable childcare and flexible work arrangements to stay in formal jobs, while rural mothers need support to maintain their income within the flexible, often informal, economy they already navigate. Without such targeted interventions, the gap between the economic lives of mothers and fathers is likely to persist, reinforcing a cycle of inequality that begins with the birth of a child.
