Toward Better Informed Decision-Making: the Impacts of a Mass Media Campaign on Women's Outcomes in Occupied Japan (Job market paper, 2019)

Lack of access to information undermines our optimal decision-making. It is, however, an empirical question whether targeted information campaigns toward less-informed populations change their decision-making. This question is particularly salient to gender issues as past research shows that women are often disadvantaged in information acquisition. In this paper, I shed light on women's radio programs that were aired in Japan under the US-led occupation (1945-1952) and brought new information to Japanese women. Exploiting local variation in radio signal driven by soil conditions as an instrumental variable, I identify and estimate the causal impacts of exposure to women's radio programs on female political participation, labor market participation, marriage, and fertility decisions. I find that, in areas where women were more exposed to women's radio programs, women turn out more and female candidates gain more votes in the first election after World War II. Moreover, information provision through women's radio programs significantly contributes to the fertility decline and therefore has an important implication for the nation's demographic landscape. Female labor force participation and marriage remain the same, suggesting that the declining fertility is neither due to women's greater aspiration for their career nor to decline in marriage. My results are not driven by a pre-existing correlation between radio signal and women's behavior before the US occupation. My findings provide evidence that a targeted information campaign can affect recipients' behavior. They also lend support to the contemporary initiatives by the UN, NGOs and NPOs to use mass media to reach out to women who have limited access to information.

The Consequences of Increased Women's Representation in Politics: Evidence from Japan (2018)

The female share of the Japanese national legislature began trending upwards in the mid-1990s, after 50 years of hovering around three percent. To better understand the consequences of this change, I examine the impact of female office holding on electoral and public policy outcomes in the context of the Japanese House of Representatives in the last two decades (1996-2017). To isolate the causal effect of legislators' gender, I employ a regression discontinuity design in a sample of contests where a female candidate wins or loses against a male candidate by a narrow margin. As opposed to the long-standing argument that female electoral victories lead more women to run for office, an additional female victory does not affect the number of female candidates nor female winners in the next election. This result is consistent with Ferreira & Gyourko's (2014) and Broockman's (2014) findings for US mayoral and state legislative elections. Moreover, to examine whether additional female officeholding affects legislative outcomes, I turn to patterns of petitions signed by each legislator. Unlike roll-call votes, legislators do not necessarily act along party lines when considering petitions. I find that female legislators are more likely to support petitions on subjects supported by women, namely gender issues and reproductive rights. Therefore, as models of identity politics would predict, the presence of female legislators is an important channel through which women express their needs. Furthermore, contrary to a wide-spread concern that women are less qualified as politicians than men, the gender of legislators does not affect the amount of per-capita intra-governmental transfers, which provides one piece of evidence that female legislators are as good as male legislators at serving the interests of their local constituents.

Intrahousehold welfare (2019, with Pierre-André Chiappori and Costas Meghir)

Measuring individual-level well-being is crucial when we think about public policy, and existing literature has shown that substantial inequality is hidden within the household (Lise & Seitz, 2011). Earlier work has addressed such intra-household inequality, but it has yet to account for household public goods when measuring it. To shed light on this issue, we develop a new way to measure intra-household inequality that reflects individual well-being derived from household public goods. Using a collective household model, we defined the Money Metric Welfare Index (MMWI), which is essentially a monetary amount that a person would need to reach the current utility level if she were to pay the full price of household public goods. We show that the MMWI is uniquely identified up to an increasing transformation. Then we structurally estimate the collective household model and compute the MMWI using the Japanese Panel Survey of Consumers (JPSC). The JPSC is particularly suitable for our purpose because it provides variables that the MMWI requires, including expenditure for household public goods and time use. Estimated MMWI allows us to see how the intrahousehold inequality evolved in the last 20 years.
