According to the authors, a women’s economic contribution (dependency) is measured by “her contribution to the couple’s income” (Sørensen & McLanahan 1987, 66)—namely a woman’s income relative to her spouse’s income. Since then, there have been some studies on relative earnings within couples in the United States (Raley, Mattingly, & Bianchi 2006), European countries (Arber & Ginn 1995; Van Berkel & De Graaf 1998; Ward, Dale, & Joshi 1996) and Japan (Sangu 2002). Furthermore, with the increase in the availability of cross-national datasets, there has been some recent cross-national 1 Some researchers refer to this issue as “economic dependency”. The terms vary according to assumptions regarding the role of women. I use the term “economic contribution” in this chapter. 42 Saki Kudo Nicol Foulkes Savinetti & Aart-Jan Riekhoff (eds) research (Bianchi, Casper, & Peltola 1999; Estévez-Abe & Hethey 2008; Stier & Mandel 2009). According to these studies, the economic contribution of European and American women has increased over the years, even though women tend to depend on their husbands’ earnings. Furthermore, some scholars found that the number of women who earn more than men has also risen gradually and they have examined the patterns of those couples (Winkler, McBride, & Andrews 2005; Winslow‐Bowe 2006). However, Japanese women’s contribution has continually shown high dependency (Sangu 2002). What are the determinants of the recent increase in women’s economic contribution? According to previous studies, the determinants can be divided mainly into individual and institutional settings. First, in terms of the individual level factors, human capital theory (Becker 1975) is one of the leading explanations for women’s economic contribution. For example, education and age are considered the main factors of productivity, meaning that when the individual’s education or age is higher, the economic contribution also increases. Moreover, the number of children and presence of preschool children are crucial determinants of women’s economic contribution from householdlevel perspectives. For example, childcare suspends work for at least some years and decreases the caretaker’s economic contribution (Raley et al. 2006). On the other hand, institutional factors such as family policies that moderate women’s worklife balance are important explanations of women’s economic contribution. Most studies indicate that family policies, such as maternity leave and the creation of affordable childcare, are influential in increasing women’s economic contribution.2 2 Other explanations are provided by Estévez-Abe and Hethey (2008), who argue that other countrylevel factors such as the degree of employment protection and the size of the public sector affect women’s economic contribution. I do not address these factors in this paper, but they are also important in terms of women’s economic standing. Cross-national analysis of women’s economic contribution 43Shaping and re-shaping the boundaries of working life The main findings regarding institutional factors are as follows: some researchers advocate the view that family policies enhance women’s employment rate (Kenjoh 2005), continuity of employment (Stier, Lewin-Epstein, & Braun 2001) and fertility level (Björklund 2006). On the other hand, others argue that long leave provision and childcare benefits could ultimately have negative effects on the women’s career and earning prospects (Rønsen & Sundström 2001). The prevalent conclusion about the impact of public childcare on women’s employment is that generous public childcare enhances employment rates among married women and women with young children (Korpi 2000; Pettit & Hook 2005; Uunk, Kalmijn, & Muffels 2005). This is supported by data considering different points in time (Uunk et al. 2005) as well as by crossnational comparisons (Korpi 2000; Pettit & Hook 2005). However, one determinant has been ignored in these previous studies: women’s lifestyle preferences3. A central discussion on this issue is represented by Hakim’s (2000) preference theory, which posits that there are three types of typical female preferences. According to the theory, a minority of women falls into the work-oriented and home-centred categories, while the majority falls into the adaptive career category, combining paid work with childcare. Is the economic contribution explained either by women’s lifestyle preferences or by the implementation of family policies? Referring to the study of Stier and Mandel (2009), I establish an appropriate model to test this question. According to Stier and Mandel (2009), family policy plays a role in moderating women’s economic contribution 3 Although preference theory has received attention from many researchers, it also has some critics. For example, some studies argue that women’s career decisions and life satisfaction are determined by multi-dimensional aspects, and it is important to consider their interrelation with each other (e.g. Blackburn, Browne, Brooks, & Jarman 2002; Warren 2004). In the view of these critics, for instance, the financial situation, leisure time, social policies and the power of the employer should be taken into account when women’s preferences are examined because the female life course is restricted by such factors. 44 Saki Kudo Nicol Foulkes Savinetti & Aart-Jan Riekhoff (eds) through labour force participation—long maternity leave decreases women’s economic contribution in the short run, whereas higher rates of childcare provision increase contributions. However, Stier and Mandel’s study does not explain the effect of women’s lifestyle preferences; thus, I include women’s lifestyle preferences in my model. Furthermore, there is a need to include countries such as Japan, which have shown a low female economic contribution (Sangu 2002). Hypotheses This chapter addresses the primary question “Is women’s economic contribution explained by family policy implementation or female lifestyle preferences?” The subsequent hypotheses are established in order to test this question. First, I examine the effect of women’s attributes on their economic contribution from individual and institutionallevel perspectives. According to Stier and Mandel (2009), institution-level factors are expected: 1.1) Long maternity leave decreases women’s economic contribution in the short term. 1.2) An increase in the percentage of childcare facilities leads to an increase in women’s economic contribution. Second, women’s lifestyle preferences are examined. According to preference theory (Hakim 2000), there are different types of lifestyle preferences: home-oriented, adaptive lifestyle and work-oriented. Therefore, I assume that there is a variance in women’s career preferences, and the hypothesis is thus stated: 2) The more a woman’s lifestyle preference is career-oriented, the higher her economic contribution is. Last, I expect that family policies might restrict the lifestyle choices of women because women might consider their career in light of the policy conditions. Furthermore, as previous studies show, Cross-national analysis of women’s economic contribution 45Shaping and re-shaping the boundaries of working life women’s economic contribution varies from one country to another, and there is no convergent consequence. Thus, I presume that the economic contribution is explained by institutional factors rather than individual lifestyle preferences. Considering these reasons, the hypothesis of the relationship between family policies and lifestyle preferences is thus: 3) Family policies affect women’s lifestyle preferences to moderate toward being career-oriented. The hypotheses stated above will be examined in the sections below. Data and variables In this chapter, there are two levels of datasets: individual and institutional levels. I use The International Social Survey Programme (ISSP 2014) to investigate individual-level determinants. ISSP is a cross-national dataset created by annual surveys on diverse social topics. The data are from 2012; since the theme of that year’s survey was Family and Changing Gender Roles, I deem the data appropriate to measure the balance within couples.4 The data used for the main analysis contain 27 countries and 6,449 female respondents with partners.5 Furthermore, the age of respondents is 25–60 years as a 4 In a previous study (Stier & Mandel 2009), the Luxemburg Income Study (LIS) data were used, but they do not include the question of women’s career preferences. More precisely, there is a question on “employment situation desired” in the LIS data, but it does not explain the lifestyle preference of the balance between family and work; it indicates the desired career position rather than the current working condition. For this reason, I consider ISSP a more appropriate data source to measure female lifestyle preferences. 5 Since cohabitation without marriage is common in some countries, I include the respondents with partners. The data for East and West Germany are merged in this paper. The countries used are Argentina, Australia, Canada, Chile, Croatia, the Czech Republic, Denmark, Finland, France, Germany, Iceland, Israel, Japan, Latvia, Lithuania, Mexico, Norway, Poland, Slovakia, Slovenia, South Korea, Spain, Sweden, Switzerland, the United States and Venezuela. 46 Saki Kudo Nicol Foulkes Savinetti & Aart-Jan Riekhoff (eds) proxy for the workingage population. The institutionallevel data were obtained from an online database from the OECD and UNESCO. The detailed summary of the institutional-level data is shown in the results section. Individual-level variables The main dependent variable is “women’s economic contribution”. I used question 22 from the ISSP: “Who has the higher income?” The question is answered on a sevenpoint scale with the contribution increasing with a rise in the number.6 Other individual-level variables are education and age as factors of human capital. In addition, the number of children (under 18 years old), the presence of preschool children, and household income were included as household characteristics. Women’s lifestyle preferences were measured by the statement: “A job is all right, but what most women really want is a home and children,” which was answered on a fivepoint scale (from zero to four) describing to what extent the respondent agreed with the statement.7 Last, I made the dummy variable of “work,” which indicates whether the woman works or not. The summary statistics of the individual variables are shown in Table 1. 6 In a previous study (Stier & Mandel 2009), women’s economic contribution is calculated by the following equation: women’s economic contribution=[(Fwage) / (Fwage) + (Mwage)]. However, i) there is no question on the wage of the respondent and the partner in this questionnaire and ii) the answer on income has different scales in each country. Hence, I assume that using question 22 is a more appropriate indicator than the question on income. 7 It is not fully appropriate to use this question to measure “lifestyle preferences,” as this question might show only the personal values toward public opinion. Future studies should utilise a more precise question that asks directly the preferred lifestyle choices, such as the ideal career and level of family responsibility. Cross-national analysis of women’s economic contribution 47Shaping and re-shaping the boundaries of working life Table 1. Individual-level variables Individual-level Variable NMean S.D. Min. Max. Woman’s Contribution 6,449 3,38 1,55 1 7 Woman with BA 0,53 0,50 0 1 Woman’s Age 43,03 9,74 25 60 Difference of Age (male-female≥5) 0,25 0,43 0 1 Household Income (Log) 10,02 2,71 016,81 Woman in the Labor Force 0,73 0,45 0 1 Number of Children 0,73 1,02 021 Presence of Children (Preschool) 0,29 0,45 0 1 Preference (Higher: Work-Oriented) 2,27 1,27 0 4 It appears that the women’s contribution is slightly less than the men’s (mean of women’s contribution = 3.38 on a seven-point scale), and many women are in the labour force (mean of work dummy = 0.727). These numbers indicate that the women’s average contribution to the household is much closer to that of the men’s. It shows that most couples are dual-earners; both partners are in the labour market to some extent in either a part-time or a full-time setting. In addition, the average of women’s lifestyle preferences is 2.27, which means that slightly more than half of women really want to work rather than stay home to take care of the children. Institutional-level variables In terms of institutional-level variables, I focused on the length of paid maternity/parental leave (in weeks) and the percentage of public education participation. I also added the proportion of female parttime workers (female entire) in the country as a control variable. The country-level summary statistics are represented in Table 2. 48 Saki Kudo Nicol Foulkes Savinetti & Aart-Jan Riekhoff (eds) Table 2. Country-level variables Macro-Level Variable NMean S.D. Min. Max. Long Maternity Leave 27 0,45 0,49 0 1 % in Public Childcare(preschool) 71,13 0,28 1,91 99,27 % Women Working Part-time 23,64 10,40 5,10 45,60 According to previous studies, long maternity leave has a negative effect on women’s economic contribution in the short term (Stier & Mandel 2009). Thus, paid maternity leave was measured as a dummy variable in terms of whether it was longer than average or not. In the dataset, the average paid leave was 51.27 weeks, thus a dummy variable was created as “long=1” when it was more than 52 weeks, or else “other=0”. The percentage of public education for preschool children varied across the countries from a minimum of 2% to a maximum of 99%.8 Furthermore, the percentage of female part-time workers was considered as a control variable. The model Because cross-national data have a nested structure, as individuals are included in each country, a multilevel analysis is an appropriate method for examining the determinants of women’s economic contribution. Multi-level analysis can consider the intraclass correlation—namely, the similarity of observations in the same country, which is a violation of the basic assumption of statistical tests regarding the independence of individual respondents (Hox, Moerbeek, & Van de Schoot 2010). First, the individual characteristics are described: (Women’s Economic Contribution)ij = β0j + β1j (Preference)1j + βX+ eij, Where β0j is the intercept, βX is a vector of individual factors and eij describes the error term. Using the multilevel analysis, I presume that the intercept varies from one country to another: Cross-national analysis of women’s economic contribution 49Shaping and re-shaping the boundaries of working life β0j =γ00 + γ01(Maternity leave)j + γ02(Public education)j + γX + u0j. Here, γ00 is the country-level intercept, the other γs are country-level slopes on the individual intercept, and u0j is the error term. As the equation denotes, individuals in the same country are regarded as having the same country-level factors in this analysis. Last, in order to examine Hypothesis 3 (Family policies affect women’s career preferences to moderate toward being careeroriented), I made the slope of the preference random: β1j =γ10 + γ11(Maternity leave)j + γ12(Public education)j + u1j. Therefore, if family policies improve the career prospects as I assume, then both coefficient γ11 and γ12 will be positive. Results Figure 1 shows the distribution of women’s economic contribution on a seven-point scale (from one: “I have no income,” to seven: “My spouse/partner has no income”. Category four is a middle option: “We have about the same income”).9 According to Figure 1, in most countries, the women tend to rely on their partner’s income. However, the dependency rate varies from one country to another. For example, women in the East Asian and South American regions have a significantly higher dependency rate. On the other hand, couples from European countries have relatively minor differences in their income, indicating that Category 3 is the dominant option. 9 In the original data, the order of the scale is the other way around. Moreover, I created Figure 1 using those respondents included in the main analysis. 56 Saki Kudo Nicol Foulkes Savinetti & Aart-Jan Riekhoff (eds) larger sample could be used in order to show more robust results. Second, there are some important outstanding questions, which, for example, could address how policy shifts or geographical features have an effect on economic contribution. These questions could be studied utilising different methodologies, such as panel data analysis or spatial analysis. Lastly, there is a need to consider the partner’s cooperation—for example, the division of household work (Brines 1994; Greenstein 2000), fatheroriented policies (Eydal & Rostgaard 2015) and equivalent determinants. In the main analysis, the household income and age difference are considered, but the demographics of the partner may have strong effects on the woman’s relative contribution. This should be considered carefully in future research.13 13 I would like to acknowledge the anonymous reviewers for their useful suggestions.
