We find that both information and advice from these sources enhance children's willingness to share. Their sharing increases after observing others' decisions, except when it is costly to access information about parents' behavior. However, when children must incur a small cost to observe others' behavior, their sharing responds substantially more to their teachers' and peers' behavior than to their parents'. By contrast, advice from all sources—parents, teachers, peers, and high-status peers—consistently enhances sharing. Our findings highlight the crucial role of children's social environments and shed light on multiple policy-relevant channels for fostering altruism among underprivileged children.</div></div>","PeriodicalId":48418,"journal":{"name":"Journal of Development Economics","volume":"181 ","pages":"Article 103750"},"PeriodicalIF":4.6,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146189297","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We conduct a two-phase study decomposing this relationship by examining (i) job take-up decisions and (ii) labor supply, output, and earning conditional on job take-up, and (iii) quit rates. In Phase 1, women in rural Ghana are asked whether they would be willing to take-up a cash-for-work job during the lean season when alternative work is scarce. We find that individuals with depression and anxiety, which are common in this population, are much more likely to decline work offers outside the home but equally likely to accept work-from-home positions. In Phase 2, we randomly offer jobs at home to those who were willing to work from home, avoiding selection effects. Neither depression nor anxiety predict work completion, income, or quit rates when working from home. These findings suggest that poor mental health may harm labor market outcomes in traditional jobs outside of the home via reduced take-up, above and beyond the established negative impacts of mental health on productivity in work outside of the home. But, the results also suggest an alternative approach to improving labor market outcomes for those in poor mental health: work-from-home opportunities, which are not associated with lower take-up or lower productivity on the job for those in poor mental health.</div></div>","PeriodicalId":48418,"journal":{"name":"Journal of Development Economics","volume":"181 ","pages":"Article 103734"},"PeriodicalIF":4.6,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146189298","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Analysis after 2007 however is hampered by problems in the key data source for empirical analysis, the National Bureau of Statistics’ (NBS) annual survey of industrial firms. Issues include missing information on value added and intermediate inputs, and concerns of over-reporting. The annual survey of firms conducted by China’s State Taxation Administration (STA) provides a reliable, alternative source of firm-level data for the years 2007 to 2013. Since the sample is not representative and the precise sampling scheme is not known, the data cannot be used directly to draw inferences on China’s manufacturing sector. By comparing the joint distribution of key variables for which both surveys provide reasonably reliable information, we recover the sampling scheme of the STA survey and use it to simulate samples for 2007 to 2013 that are comparable to the NBS sample in earlier years. Our estimates reveal a marked slowdown in revenue-based total factor productivity growth that cuts across all industries, ownership types, and regions. The loss of dynamism in the private sector, and the reduced contribution of firm entry to aggregate productivity growth are especially prominent.</div></div>","PeriodicalId":48418,"journal":{"name":"Journal of Development Economics","volume":"181 ","pages":"Article 103720"},"PeriodicalIF":4.6,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146039649","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We develop a flexible theoretical framework in which insecurity, a latent production cost, affects firms’ market entry, exit, and formality decisions. In our empirical analysis, we combine an original dataset on Afghan firms with georeferenced data on military events that we use to proxy insecurity. In the state-building context of post-2003 Afghanistan, military events reflect not only violence but also state capacity expansion. For formal firms, this latter channel dominates. As a result, increased exposure to military events conveys on average a reduction in effective insecurity and positively impacts formal firm existence. Nonetheless, this effect is highly heterogeneous depending on actors, location, timing and firms’ characteristics. The Afghan conflict has the specificity of deeply involving foreign countries. Mobilizing this particular source of exogenous variation, we identify the causal effect of an insecurity reduction on formal firms’ existence. We show that an increase of 1% in the exposure to instrumented military events raises the formal activity probability by 3.8%.</div></div>","PeriodicalId":48418,"journal":{"name":"Journal of Development Economics","volume":"180 ","pages":"Article 103714"},"PeriodicalIF":4.6,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145977313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
