1 The study’s contribution

The authors study the relationship between the change in prices of the housekeeping services and the labour decisions and time use of native females. This relationship happens even without any impact on wages. Cortès (2008) has found that the waves of low-skilled immigrant have led to a decrease in the prices of housekeeping services which should lead to people spending less time in household production. Indeed, the opportunity cost of engaging someone to do it in their stead is reduced so they have more incentive to spend more time working and less time doing household production.

The authors first develop a theoretical model to assess which social categories of women are concerned by the phenomenon and then test the results empirically using census data on immigration and labour supply and information about time spent to household production and reported expenditures on housekeeping services.

They want to exploit the cross-city variations in immigration. The first problem they might encounter is endogeneity in locations, that is, some cities might be systematically different from others. To check that this is not the case, and that the identification assumption is not violated, they control for some shocks that could have happened in 1970 on the cities key variables like female educational attainment and participation to work as well as the industry composition. They then use the immigrants’ distribution of 1970 to determine their choice of location in 1980 and 1990. The second problem is that female labour force participation could be affected by other channels than the reduction in housekeeping price. The authors then choose to take the male labour force participation as a control group and check whether their participation change and whether women have an increase in wage compared to men. Finally, the authors test the relevance of the time-use decision mechanism by comparing the estimated pattern of the immigration effect by skill level of women with the predicted pattern given by the model and look at the mirror decisions of housework and consumption of housekeeping services.

Comparing the effect of the flow of low-skilled immigrants on supply of hours worked and on educational attainment of women as a control. The effects are similar on women at the top wage distribution and women with a high level of education since many of them are the same people. This shows the close link between education and wage.

Using men labour supply as a control. It is not common to do so since they have labour participation trajectories rather different. However, men and women at the top of the distribution are more likely to react the same way to economic incentives. We can also notice that the more women have invested in their education, the more they work and the more similar is their labour supply to males’ labour supply. Indeed, the opportunity cost of not working is much higher when you have invested in your education. Hence, men and women at the top wage distribution are much closer than men and women at the bottom wage distribution. Still, the authors control whether female workers have children below or above five years old because it impacts their labour force participation more than men. They also include city x decades fixed effects to control first the choice of location of immigrants in 1970 that still might be relevant for labour supply decisions (no difference between male and female is assumed). Second it controls whether the inflow of low-skilled immigrants can have an impact on natives’ labour supply through complementarity in the production process.

2 Critical assessment of the study

Maybe comparing female to female evolution would be more relevant. Taking a sample of women in where there is lower low-skilled immigration or no-skilled immigration and check whether women have incentives to participate more in the labor market through wages for example. Here, the authors use the male labor force participation but male and female have very different conditions on the labour market, especially in 1970 where many women were still stay-at-home. However, men and women at the top of the distribution are more likely to react the same way to economic incentives. We can also notice that the more women have invested in their education, the more they work and the more similar is their labour supply to males’ labour supply. Indeed, the opportunity cost of not working is much higher when you have invested in your education. Hence, men and women at the top wage distribution are much closer than men and women at the bottom wage distribution.

Including males labour force participation as a control group still has limitations. First, males are usually less involved in household work. This means that a decrease in the price of housekeeping services will less affect their labour supply. Therefore, the estimates of the control group are then a lower bound for the female group. Indeed, the estimates confirm that high-skilled females have reacted more than high-skilled males to the inflow of low-skilled immigrants. An interaction variable between men and women is added to measure the impact of their interaction on time-use decisions given the inflow of low-skilled immigrants. However, what stands out is that women have received relatively lower wages compared to men in cities with massive inflow of immigrants.

Many services are not accounted for here: gardening, laundry, grocery shopping while these activities are among the main housekeeping services and are accounted for in household production. This means that the study provides a lower bound for the effect of the immigrants’ inflow on the purchases of service market.

Maybe actualise this study could be relevant. Today, we may have more data on housekeeping services, including gardening, laundry and grocery shopping, however, another limitation is that housekeeping services can be done illicitly and not be declared. Maybe taking into account the estimated share of illicit work would get us closer to the real impact of housekeeping services. There are probably more single fathers now than before which could represent a good control group for mothers and especially single mothers. Furthermore, with schooling inflation, there are more high educated women than in 1970, 1980 and 1990 so the results could be even more significant.

In the concluding remarks, the authors suggest that there are some barriers due to the lack of affordable housekeeping services. However, they assume that women are more attached to family life than men. Maybe another explanation can be found in the social norms and preferences. In the last century, women have obtained a lot of rights that made them more independent from their husbands, however, that was still quite recent in 1970 and 1980. So, there may be an adaption time from society to these new rights and norms. Task sharing was less equal than today in the norms so that may be a clue of why women are more penalised than men by the lack of affordable services.
