We analyze the distributive and aggregate effects of SSA in a rich life-cycle model with heterogeneous agents and incomplete markets. The model is estimated to be consistent with micro and macro data from Brazil. Our analysis reveals that, despite a decrease in voluntary savings, the policy expands aggregate savings, output, and wages, leading to long-run welfare gains. We show that although better risk sharing is important for our findings, the bulk of the gains come from improved efficiency as labor productivity increases and labor supply is reallocated towards highly educated workers and the early stages of the life cycle where agents are generally poorer and leisure is less valued. Interestingly, most of the gains we find accrue to less educated agents as the distribution of this group is skewed towards the informal sector, and they do not directly incur the additional burden from the increase in contributions. We also explore an alternative policy design in which households are allowed to access their severance savings accounts only after retirement, as in a defined contribution pension system. We find that despite greater uncertainty in medical costs later in life, households prefer a more flexible system that provides access to the SSA fund during working-age and after retirement.\u0000</p>","PeriodicalId":47982,"journal":{"name":"Economic Theory","volume":"43 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2024-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141568956","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Trade liberalization promotes innovation and growth when intellectual property rights (IPR) protection is sufficiently weak. Trade on the other hand does not affect innovation and growth when IPR protection is strong. We show that this result holds for both horizontal and vertical endogenous growth models, which have so far had contradictory predictions on how trade affects innovation. The reason for this supposed contradiction are implicit IPR protection assumptions in the two different types of growth models, strong protection in the horizontal model and weak protection in the vertical model. The IPR protection assumption makes a big difference for the size of the gains from trade. In a simple numerical example we show that assuming weak IPR protection can imply more than five times higher overall gains from trade. We also build a North–South model and add another aspect of IPR protection influencing the duration of Northern patents, namely imitation in the South. In the asymmetric model with a competitive fringe in the South, IPR protection no longer plays a crucial role for the dynamic gains from trade.</p>","PeriodicalId":47982,"journal":{"name":"Economic Theory","volume":"124 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2024-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141515423","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We build up a model of electoral accountability with pure moral hazard and bring it to the lab. Politicians must decide whether to invest in a public project with uncertain returns or to keep the funds for themselves. Voters observe the outcome of the project but not the action of the politician; if the project is unsuccessful, they do not know whether it was because of bad luck or because the politician embezzled the funds. We run two treatments; a control and a treatment where subjects are assigned an identity using the minimal group paradigm. Our main result is that, upon observing a failed project, voters approve politicians of their same identity group significantly more often than in the control and compared to politicians of a different identity group. This is partially driven by a belief on same-identity politicians being more honest. We also observe that subjects acting as politicians embezzle funds less often than expected by the equilibrium prediction.</p>","PeriodicalId":47982,"journal":{"name":"Economic Theory","volume":"71 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2024-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141506448","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We are then able to recover the increasing shares of workers, the increasing real and nominal shares of the output observed in productive service and IT sectors in the US.
