Electrocardiograms of 954 patients (median age: 62 years; male: 86%; mean follow-up: 2.1 years) were acquired prospectively within 48 hours before CABG (T1) and within 24 hours after CABG (T2).

For that, we perform by far the largest available meta-analysis of the finance–growth nexus using 3561 estimates collected from 177 studies. Our meta-synthesis results show that large heterogeneity in empirical evidence is, in fact, driven by only a limited number of variables (moderators). By using advanced techniques, we also document the existence of the publication selection bias that is propagated in the literature in a nonlinear fashion. We account for uncertainty in moderator selection by employing model-averaging techniques. After adjusting for the publication bias, the results of our meta-regression provide evidence of a small but genuine positive effect of the financial development on growth that very mildly declines over time. Finance channeled via capital markets seems to be more beneficial for economic growth than that provided in the form of private credit. Our evidence goes against arguments about the damaging role of financial development and is in line with century-old theoretical foundations that favor the positive role of finance on economic growth.</p>","PeriodicalId":11642,"journal":{"name":"Empirical Economics","volume":"1 1","pages":""},"PeriodicalIF":3.2,"publicationDate":"2023-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139026988","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We provide comparable quasi-experimental estimates of the childcare effect for seven countries, using harmonized data and a uniform method based on country-specific childcare eligibility cutoffs. We evaluate the estimates in light of key institutional factors to determine under what conditions childcare expansion is likely to be effective. We propose a measure that captures childcare scarcity and predicts the effectiveness of childcare expansion: the gap between the participation rate of mothers with older children (aged 6–14) and childcare coverage under the age of 3. In countries with a high gap, we find that childcare availability has a significant positive impact on maternal labor supply (Austria, Czech Republic, Hungary, Slovak Republic). No significant impact is found in countries where the gap is low due to either already high childcare coverage (France) or the low participation of mothers with older children (Greece, Italy). We discuss other policies that need to be addressed concurrently for childcare expansion to achieve its goal of increasing mothers’ participation in the labor market.</p>","PeriodicalId":11642,"journal":{"name":"Empirical Economics","volume":"51 1","pages":""},"PeriodicalIF":3.2,"publicationDate":"2023-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138687279","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to decompose the changes in house prices, structural vector autoregression with sign restrictions for the US housing market is applied. In addition to including housing market-based fundamental variables such as the number of housing permits, housing rent prices, house prices, a measure of credit conditions, and the housing sentiment index are also included to distinguish four different shocks, namely housing supply shocks, shocks to the housing service demand, credit shocks, and speculative demand shocks. Empirical findings show that the main contributors to house price fluctuations are credit shocks and housing supply shocks in the long-run. In addition, while housing supply and credit conditions are the most important contributors during the boom, the contributions of credit conditions and speculative demand become larger after the boom. In fact, credit conditions are the largest contributor during the post-boom period.</p>","PeriodicalId":11642,"journal":{"name":"Empirical Economics","volume":"7 1","pages":""},"PeriodicalIF":3.2,"publicationDate":"2023-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138575291","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
