Do not hide my perplexity to this research, a study by two economists from the Bank of Italy says that a child under 23 months reduces the likelihood of a woman having a job, but after the first two years there are negative aspects of motherhood on labor supply of women.
In summary much depends on the age, a child under 23 months reduces the likelihood of a woman to have paid employment and decrease the chance still increasing in number.
But over time diminish the difficulties and return to work is possible, the presence of children seems to have a slight effect for mothers to push into the labor market, perhaps the impetus is the need to live. Too bad that after two years of sleep is almost impossible to find work, especially in a country economically strong and able to put as an apprentice up to 29 years and more than one located in southern Italy. A mom that has exceeded 30, with two children, cabbage, may become ill, honestly is put immediately in the queue in the list of candidates.
In addition to returning to work had to have a permanent place first, including temporary employment, and such, this study seems to me unrealistic, but apparently the search does not hide the fact that there are other problems, such as the inability to make a career.
