Biased Aspirations and Social Inequality at School: Evidence from French Teenagers 有偏见的愿望和学校的社会不平等:来自法国青少年的证据

Using unique data on aspirations, academic performance and actual track assignment to high school of French ninth graders, we show that low-SES students have lower aspirations than their equally-achieving high-SES classmates, and that track assignments to high school the next year are even more unequal due to dysfunctional dynamics: first, both low aspirations and low SES are associated with slower academic progress over the year. Second, aspirations and parental SES play a role in track assignment independent of one’s academic performance. Our results suggest that, in France, an aspirational trap at school contributes to the poverty trap, leading to the perpetuation of social inequalities.","PeriodicalId":325508,"journal":{"name":"Sciences Po publications","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115557472","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 investigate the linkages between price stability and these objectives to assess whether they are independent, complementary or substitutable, which is important to refine the definition of the mandate. Keeping the current mandate would not provide leeway for the ECB to reach other objectives. We propose to broaden the mandate to include employment and financial stability. Enhanced coordination should contribute to fulfilling the objectives.

This paper uses real time survey data from two waves run at the end of March and in mid-April to provide a snapshot of the actual labour market outcomes in twelve countries. Our study reveals large cross-country differences. At the end of March, when large disparity existed in the diffusion of the pandemic and in the lockdown measures, a large share of employed individuals had stopped working in France (38%) and Italy (47%), but much less in Australia (13%) and the US (10%). Large differences remained in mid-April. Yet, some common patterns emerge. Labour market outcomes varied according to workers’ educational attainments and occupation types. College graduates and white collars worked more from home and less from the regular workplace. Instead, low educated workers and blue collars were more likely to remain in the regular work place or to stop working. Similar patterns emerge with respect to the workers’ (family) income. This evidence suggests that initial labour market effects of COVID-19 (and of the lockdown measures) may have contributed to increase pre-existing inequalities.","PeriodicalId":325508,"journal":{"name":"Sciences Po publications","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116090949","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 restrict our attention to models with a finite number of state variables. We first give some insights on the solution methods for linear models. Second, we show how to use the perturbation approach for solving non-linear models. We then document the limits of this approach. The perturbation approach, while it is the most common solution method in the macroeconomic literature, is inappropriate in a context of large fluctuations (large shocks or regime switching) and of strong non-linearities (e.g. occasionally binding constraints). The former case is then illustrated extensively by studying regime switching models. We also illustrate the latter case by studying existing methods for solving rational expectations models under the Zero Lower Bound constraint, i.e. the condition of non negativity of the nominal interest rate. Finally, we end up with a brief presentation of global methods which are alternatives when the perturbation approach fails in solving models.","PeriodicalId":325508,"journal":{"name":"Sciences Po publications","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114843738","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}

When private agents can only provide limited incentives for the central bank to follow a policy, we show that resulting limited credibility allows a central bank to prevents the inflation from diverging by defaulting on past promises if necessary. As a result, the Taylor rule, when expected, anchors inflation expectations on a unique equilibrium path as long as the Taylor principle is satisfied. Finally, we also show that limited credibility restricts the impact of long-term interest rate pegs, so as to make current conditions less dependent on future policy changes.","PeriodicalId":325508,"journal":{"name":"Sciences Po publications","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124519447","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}

When Keynes goes to Brussels : a New Fiscal Rule for the EMU ? 当凯恩斯去布鲁塞尔:欧洲货币联盟的新财政规则?

Saraceno","doi":"10.26331/1019","DOIUrl":"https://doi.org/10.26331/1019","url":null,"abstract":"The Economic and Monetary Union (EMU) institutions are consistent with a New Consensus that emerged in the 1980s, limiting the role for macroeconomic (particularly fiscal) policy to short term stabilizations by means of rules. I will argue that the policy inertia induced by the Consensus may have played a role in the disappointing performance of EMU economies even before the crisis. The crisis of the Consensus, and the debate on secular stagnation, proved that Keynesian (and possibly) persistent excesses of savings over investment may hamper growth. This has put fiscal policy back to the center of the scene, and given the General Theory, at eighty, a second youth. I will argue therefore that the EMU fiscal rule should be amended to allow semi-permanent negative government savings. I will finally argue that a modified Golden Rule may serve this objective, and allow EU-wide policy coordination. This seems the only reasonable reform with some chances of being adopted by the EU divided policy makers.","PeriodicalId":325508,"journal":{"name":"Sciences Po publications","volume":"82 3 Suppl 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132564042","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}
