We find that robot adoption increases employment by augmenting the number of care workers and nurses on flexible employment contracts, and decreases difficulty in staff retention. Robot adoption also reduces the monthly wages of regular nurses, consistent with reduced burden of care. Our findings suggest that the impact of robots may not be detrimental to labor and may remedy challenges posed by rapidly aging populations.","PeriodicalId":19091,"journal":{"name":"NBER Working Paper Series","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75434794","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A social solution arises when a situation is resolved at the group level (rather than the individual level) through cooperation and fair distribution of the resulting surplus. In human societies, childcare and education for the young, retirement benefits for the old, health care for the sick, and income support for those in need are resolved at the social level and through the social state in advanced economies. Social situations are pervasive even outside government and play a significant role in the distribution of pretax market incomes.","PeriodicalId":19091,"journal":{"name":"NBER Working Paper Series","volume":"34 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73008137","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Poverty in China Since 1950: A Counterfactual Perspective 1950年以来中国的贫困:一个反事实的视角

Ravallion","doi":"10.3386/W28370","DOIUrl":"https://doi.org/10.3386/W28370","url":null,"abstract":"The other side of the coin to post-reform success is often pre-reform failure, and the policy lessons are found on both sides. The paper estimates how much of China’s poverty rate around 1980—near the outset of Deng Xiaoping’s pro-market reforms—is attributable to the prior Maoist regime. Based on the history, it is argued that South Korea and Taiwan provide a relevant counterfactual. Then a difference-in-difference estimate using historical data indicates that about two thirds of China’s poverty in 1980 is attributed to the impact of the Maoist path since 1950. Further checks and tests suggest that (if anything) this is likely to be an underestimate. It took 10-20 years for China’s post-reform economy to make up the lost ground. The impact of the Maoist path had begun to fade in the 1970s, and half or more of the catch-up was in period up to 1990, under Deng’s rule.","PeriodicalId":19091,"journal":{"name":"NBER Working Paper Series","volume":"65 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89449529","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Gender Differences in (Some) Formative Inputs to Child Development (一些)对儿童发展的形成性输入的性别差异

I investigate gender differences in some of these inputs in the US and Canada. In the US very low birthweight males face excess mortality compared to their female counterparts. I provide evidence that the previously documented increase in mortality with the withdrawal of critical care at the Very Low Birth Weight (VLBW) threshold is primarily for boys. The fact that the critical care of both boys and girls changes discretely at this threshold suggests a possible misallocation of scarce hospital resources. In the US first born girls are breastfed longer than first born males, but the difference is so small that it is unlikely to have any consequence. Finally, mothers in the US and Canada are more likely to experience depression post birth when the first born child is a boy. Perhaps related, the parenting of first born boys in Canada in the first years of life is more likely to be confrontational.","PeriodicalId":19091,"journal":{"name":"NBER Working Paper Series","volume":"24 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72678227","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper provides the first direct test of whether individuals avoid information because of image concerns. We build on a classic paradigm, introducing control conditions that make minimal changes to eliminate the role of image concerns while keeping other key features of the environment unchanged. Data from 6,421 experimental subjects shows that image concerns play a role in driving information avoidance, but a role that is substantially smaller than one might have expected.","PeriodicalId":19091,"journal":{"name":"NBER Working Paper Series","volume":"81 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83888184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To shed light on this puzzle, we disaggregate firms in the manufacturing sector by size using two newly created panels of manufacturing firms, one for Tanzania covering 2008-2016 and one for Ethiopia covering 1996-2017. Our analysis reveals a dichotomy between larger firms that exhibit superior productivity performance but do not expand employment much, and small firms that absorb employment but do not experience any productivity growth. We suggest the poor employment performance of large firms is related to use of capital-intensive techniques associated with global trends in technology.<br><br>Institutional subscribers to the NBER working paper series, and residents of developing countries may download this paper without additional charge at <a href=\"http://www.nber.org/papers/&#119;28344\" TARGET=\"_blank\">www.nber.org</a>.<br>","PeriodicalId":19091,"journal":{"name":"NBER Working Paper Series","volume":"44 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86929294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We use the death rate to control for the impact of the global pandemic and war news reported in the New York Times to capture the positive effects of the end of World War I on stock prices. Using a new weekly hand collected NYSE stock price index, we show that there is a -.73 correlation between the aggregate stock market and the death rate. Furthermore, vector autoregressions demonstrate that the death rate can explain up to 24 percent of the forecast error variance in the aggregate stock index from September 1918 until the end of the pandemic in March 1920. We also find that the flu had a significant, but varied impact on nine NYSE sectors.

Policymakers are forward looking but politically motivated: they have heterogeneous preferences and do not fully internalize the cost of pollution. This type of political economy model is often reduced to a \"modified\" planner&apos;s problem, and yields predictions that are qualitatively similar to a planner&apos;s constrained optimum, albeit with a bias: too much pollution in the steady state (or, in other applications, too little investment in public goods, too much public debt, etc.). We highlight conditions under which this reduction is not possible, and the dynamic time inconsistency generated by the political process is responsible for a new type of distortion. Under these conditions, there are equilibria in which, for a generic economy and generic initial conditions, the state evolves in complex cycles, or unpredictable chaotic dynamics. Depending on the fundamentals of the economy, these equilibria may generate ergodic distributions that consistently overshoot the planner&apos;s steady state of pollution, or that fluctuate around it.<br><br>Institutional subscribers to the NBER working paper series, and residents of developing countries may download this paper without additional charge at <a href=\"http://www.nber.org/papers/&#119;28347\" TARGET=\"_blank\">www.nber.org</a>.<br>","PeriodicalId":19091,"journal":{"name":"NBER Working Paper Series","volume":"146 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77742252","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
