However, direct attribution of climate change to anthropogenic activities using observed climate and forcing variables through statistical methods has remained elusive, partly caused by the difficulties for correctly identifying the time-series properties of these variables and by the limited availability of methods for relating nonstationary variables. This paper provides strong evidence concerning the direct attribution of observed climate change to anthropogenic greenhouse gases emissions by first investigating the univariate time-series properties of observed global and hemispheric temperatures and forcing variables and then by proposing statistically adequate multivariate models. The results show that there is a clear anthropogenic fingerprint on both global and hemispheric temperatures. The signal of the well-mixed GHG forcing in all temperature series is very clear and accounts for most of their secular movement since the beginning of observations. Both temperature and forcing variables are characterized by piecewise linear trends with abrupt changes in their slopes estimated to occur at different dates. Nevertheless, their long-term movements are so closely related that the observed temperature and forcing trends cancel out. The warming experimented during the last century was mainly due to the increase in GHG which was partially offset by the effect of tropospheric aerosols. Other forcing sources, such as solar, are shown to only contribute to (shorter-term) variations around the GHG forcing trend.","PeriodicalId":100390,"journal":{"name":"Economía Informa","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90287924","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}

If this were so, market prices would provide society with the correct signals about real scarcities. Economics—the science of scarcity— has different answers to this question. Following the principles of current epistemology, the paper reviews three theories of markets: neoclassical, bio-economics, and unified theory, analyzing their assumptions, their derived empirical predictions about the relation between market prices and scarcity, and their validity when confronted against known basic facts. Clarifying misconceptions about the nature and the role of the market mechanism in the functioning of capitalism is the expected contribution of the paper.","PeriodicalId":100390,"journal":{"name":"Economía Informa","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89379691","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}

(2002) and Chen et al. (2008) by incorporating thick-tails in the mean equation innovation using the scale mixture of normal distributions (SMN). A Bayesian Markov Chain Monte Carlo algorithm is developed to estimate all the parameters and latent variables. Value-at-Risk (VaR) and Expected Shortfall (ES) forecasting via a computational Bayesian framework are considered. The MCMC-based method exploits a mixture representation of the SMN distributions. The proposed methodology is applied to daily returns of indexes from BM&F BOVESPA (BOVESPA), Buenos Aires Stock Exchange (MERVAL), Mexican Stock Exchange (MXX) and the Standar & Poors 500 (SP500). Bayesian model selection criteria reveals that there is a significant improvement in model fit for the returns of the data considered here, by using the THSV model with slash distribution over the usual normal and Student-t models. Empirical results show that the skewness can improve VaR and ES forecasting in comparison with the normal and Student-t models.","PeriodicalId":100390,"journal":{"name":"Economía Informa","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84464179","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}

The paper builds from the multidimensional targeting challenge facing conditional cash transfers (CCTs). I analyze whether a common CCT targeting mechanism, namely, a proxy means test (PMT), can identify the poor and future school dropouts effectively. Despite both being key target groups for CCTs, students at risk of dropping out are rarely considered for CCT allocation or in targeting assessments. Using rich administrative data sets from Chile to simulate different targeting mechanisms, I compare the targeting effectiveness of a PMT and other mechanisms based on a predictive model of school dropout. I build this model using machine learning algorithms. Using two novel metrics, I show that combining the outputs of the predictive model with the PMT increases targeting effectiveness except when the social valuation of the poor and future school dropouts differs to a large extent. More generally, public officials who value their key target groups equally may improve policy targeting by modifying their allocation procedures.","PeriodicalId":100390,"journal":{"name":"Economía Informa","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73516168","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}

However, empirically analyzing tax evasion is challenging, particularly because there are few direct and reliable measures. We conduct list experiments on a large sample of households to estimate how frequently consumers are willing to be complicit in value added tax (VAT) evasion, as well as the extent of social desirability bias in respondent answers. Around 20 percent of respondents agree to make purchases without a receipt in order to avoid paying VAT; surprisingly, they are not ashamed to admit this openly. Evasion is more prevalent in places with more informality and less physical presence of the state, as well as among poorer, less educated individuals and those who disregard the rule of law.","PeriodicalId":100390,"journal":{"name":"Economía Informa","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80925794","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 exploit a novel quasi-experiment: a legal reform in 2005 that increased the portion of the income collected from mining licenses that is assigned to municipalities where mines operate from 30 to 50 percent. Our main result is a statistically significant expansion of municipal employment expenditures in mining municipalities, driven by expenditures on long-term employment. Additionally, we found a meaningful effect on allowances to the municipal council, but we did not find a robust impact on transfers to health, transfers to community programs, or municipal investment, while the increase in transfers to education is small with respect to the employment expenditures effect. These results are complemented by evidence of an increase in the mayor's probability of reelection not related to the provision of public goods, which links our findings with the clientelism mechanism of resource rents. Our results also have several implications for the fiscal decentralization debate in resource-abundant economies.","PeriodicalId":100390,"journal":{"name":"Economía Informa","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81993325","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 document the elements that lead to an overall improvement in women's economic position and find that the unconditional earnings gap turns positive once observable characteristics are considered. For instance, we find that the negative gender gap disappears when we adjust for educational attainments as a new indicator of gender gaps. In general, relative differences in returns on education and a glass ceiling effect moderated by dependent children are two of the explanatory factors allowing for the continuation of gender disparities within groups. There is also a direct association between women's representation in a given occupation/education group and the gender earnings gap.","PeriodicalId":100390,"journal":{"name":"Economía Informa","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77135334","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 find consistent results using synthetic controls to causally infer the effect of each devaluation on the stock prices of global firms active in the country at the time of the event. Our results are at odds with the predictions of the efficient market hypothesis stating that predictable devaluations should not affect the stock prices of large multinational companies on the day of the event, and even less so when they happen in small countries. We interpret these results as a suggestive indication of market inefficiencies in the process of asset pricing.","PeriodicalId":100390,"journal":{"name":"Economía Informa","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73834127","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}
