Se aprecia tambien la diversidad de disenos institucionales en las organizaciones que actuan en las politicas de desarrollo productivo en el pais. No obstante, se puede concluir que el proceso de construccion de capacidades no depende del tipo de organizacion sino de otros factores que hacen al ciclo de politica -diseno, implementacion o consolidacion- y a la identificacion mas o menos precisa de la poblacion objetivo de esa politica. Los principales desafios que aparecen para las capacidades estatales en la implementacion de politicas de desarrollo productivo estan asociados a la conformacion de coaliciones que permitan articular mejor la accion publica, principalmente al interior del propio Estado, pero tambien con el sector privado.","PeriodicalId":324969,"journal":{"name":"ERN: Latin America & the Caribbean (Development) (Topic)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115904672","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}

Basing our study on the Classroom Assessment Scoring System (CLASS) instrument, we document that the quality of teacher–student interactions is positively correlated with the performance of low-income students; however, the intervention did not affect these interactions.

The study assumes that the central bank conducts monetary policy using a Taylor-type rule and it evaluates the effects of a reserve requirement policy. The results show that although a positive shock to the policy interest rate has a direct effect on commercial banks' interest rates, there is a weak transmission to the real variables. Furthermore, an increase in the required reserve ratio is successful in reducing private sector credit and excess reserves, while at the same time alleviating pressures on the exchange rate. The findings therefore indicate that central banks in small open economies should consider using reserve requirements as a complement to interest rate policy, to achieve their macroeconomic objectives.","PeriodicalId":324969,"journal":{"name":"ERN: Latin America & the Caribbean (Development) (Topic)","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131212185","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 24 km new subway line and the extension of an existing line in Santiago (Chile) in the mid-2000s reduced the distance between more than half of schools in the city and their nearest subway station. Estimates are derived using instrumental variables and fixed effects models that account for endogeneity in the relation between student performance and school-subway network distance. Substantial closer proximity to the subway network (5 km or more) is associated with lower test scores (11 percentage points of one standard deviation). I find evidence that some mechanisms could be an increase in the student/teacher ratio, an increase in parental hours of work and a worsening in the quality of peers of students in treated schools relative to students in control schools.","PeriodicalId":324969,"journal":{"name":"ERN: Latin America & the Caribbean (Development) (Topic)","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124724526","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}

Amidst striking heterogeneity of patterns across regions, we identify a broad global trend towards financial sector de-dollarization from the early 2000s to the eve of the global financial crisis of 2008–09. Since then, de-dollarization has broadly stalled or even reversed in many economies. Yet a few of them have continued to de-dollarize. This suggests that domestic factors are also important and interact with global factors. To gain insight into such an interaction, we examine the experience of Peru since the early 1990s and find that low global interest rates, low global risk-aversion, and high commodity prices have fostered de-dollarization. Domestic macro-prudential measures that raise the relative cost of domestic dollar loans and the introduction and adherence to inflation targeting have also been key.","PeriodicalId":324969,"journal":{"name":"ERN: Latin America & the Caribbean (Development) (Topic)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114179846","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}

Due to their similar investment objectives, ETFs are considered substitutes for mutual funds. Purpose of the article: The aim of the article is to provide an in-depth insight into the issues associated with the development of financial markets in Mexico over the period 2002-2012, putting special emphasis on the development patterns of ETFs. Methods: First we use descriptive statistics to unveil basic changes and trends in the Mexican investment funds (ETFs and mutual funds). Then we use a category of the innovation diffusion models, i.e. logistic growth models, in order to explore the key development pat-terns. Data sources and methodological framework are presented in the second section of the article, with a detailed description of the innovation diffusion models applied in the research (based on 3-parametric logistic curve). The sum of assets under management of ETFs and mutual funds is considered as the size of the total investment funds market. Findings & Value added: Empirical findings indicate a significant development of the ETF market, both in terms of assets under management and market share. According to the pre-sented estimations, Mexican ETF market development can be described with the logistic growth models, and three characteristic phases of the logistic curve were clearly observable. The predicted ETF market development patterns point towards a further increase of the market share of ETFs over the next 3-5 years, yet the probability of exceeding the level of ca. 20-30% seems low.","PeriodicalId":324969,"journal":{"name":"ERN: Latin America & the Caribbean (Development) (Topic)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129020988","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}

Arbache","doi":"10.2139/ssrn.2634434","DOIUrl":"https://doi.org/10.2139/ssrn.2634434","url":null,"abstract":"Services are becoming increasingly relevant in economic policy agendas due to their growing importance in explaining the performance of enterprises, the type and form of participation of countries in global value chains, and prospects for sustained growth. New production technologies and production organization, as well as changes in consumption patterns and in the nature of manufactured goods, are bringing industry and services closer together. Empirical evidence suggests that goods and services are merging through an increasingly synergetic and symbiotic relationship to give rise to a third product that is neither a traditional industrial good nor a conventional service. This complementariness between industry and services requires both activities to be competitive for them to benefit from each other.How is the relationship between manufacturing and services in Brazil? Have services contributed to increasing industrial competitiveness? The purpose of this paper is to answer these questions from an international comparative perspective. We found that (1) The share of the service sector in GDP is disproportionately high in Brazil, reaching levels seen only in advanced economies; (2) Services account for a high and growing share of the value added in manufactured goods; (3) Services are of poor quality and prices are high by international standards; (4) Services have contributed little to enhancing industrial competitiveness; (5) The high share of services in industrial value added was led mainly by changes in relative prices; (6) The low competitiveness of services can be partly explained by the sector’s modest labor productivity, high taxation, low competition and low investment; (7) Financial services and industrial and maintenance services provided by third parties account for most industrial spending on services.It seems that integrating services into the core of industrial, technology, trade and investment policies is a key step to enhance industrial competitiveness in Brazil.","PeriodicalId":324969,"journal":{"name":"ERN: Latin America & the Caribbean (Development) (Topic)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134258079","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}
