By raising caregivers’ awareness and encouraging recommended feeding, health, and hygiene practices, these programs seek to improve children’s growth, measured in terms of height and weight. We explore the effects of one such intervention that conducted home visits and community meetings with mothers of children under two years old in El Alto, a city of high poverty concentration in Bolivia. Project eligibility was limited to just over 400 households residing within a strictly defined geographical area. We exploit the resulting geographical discontinuity to identify impacts. Three years after the project started, we find that caregivers in the intervention area show substantial gains in health- and nutrition-related knowledge (0.327σ) and practices (0.273σ) relative to their peers just outside the project boundary. We find no detectable impacts on children’s height, but observe a significant increase in the prevalence of overweight children. For contexts such as El Alto, with high prevalence of stunting and increasing risk of overweight in the same population, these results suggest that nutrition promotion interventions should reassess both content and behavioral change strategies to reduce stunting while concurrently preventing excess weight gain in children.","PeriodicalId":100390,"journal":{"name":"Economía Informa","volume":"17 1","pages":"131 - 165"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79449856","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 consensus view has emerged in the literature whereby productivity is at the core of the differences in income across nations. Over the last fifteen years, progress has been made in our understanding of cross-country income differences in part by the increasing recognition of the importance of production heterogeneity—firms—and the allocation of factors of production across them for aggregate outcomes. The progress has been enhanced by the much wider availability of microeconomic data sets of firms across a growing number of countries. There has been a productive interplay of macroand microeconomic approaches to development. Two papers in this issue of Economía reflect very well the synergy that is growing across subfields, and both papers provide valuable insights for the overall role of firms and productivity on development. Although both papers offer insights and implications that are broad across many fields in economics, I focus my discussion in the context of the macroeconomic development literature and, in particular, the connection of misallocation and aggregate productivity. In “Firm Dynamics and Productivity: TFPQ, TFPR, and Demand-Side Factors,” John Haltiwanger discusses relevant measurement issues surrounding estimates of firm-level productivity and the implied inference of distortions, misallocation, and aggregate productivity derived from a variety of microeconomic data sets of firms. What is typically meant by misallocation? The concept of misallocation is tightly related to a particular economic structure. To focus the discussion, consider a simple one-period economy where a single homogeneous good is produced by heterogeneous establishments that differ only in their productivity. That is, more productive establishments produce more output for a given set of inputs. Assume for illustration that there are decreasing returns to scale in inputs at the establishment level, although this assumption is not essential. Incidentally, the aggregate production function implied by this setting features D I E G O R E S T U C C I A University of Toronto","PeriodicalId":100390,"journal":{"name":"Economía Informa","volume":"22 1","pages":"51 - 61"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73739945","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 research hypothesis is that Mexican retail market is not a perfect competition case, because it operates as an oligopoly market. So, it is assumed that this market is dominated by a few companies, where it is possible identify a leader and other companies that behave as followers. The competition in this market can take different shapes according to the corporations’ strategies. The price is not set by free market forces but by corporations and the competition for the domestic market, in which companies deploy a set complex competitive strategies where different combinations of variables are included, variables that are not just prices. Among these variables we can find, besides price, customer service; innovations; variety of offered products; market segmentation; product quality and sales infrastructure; mergers, acquisitions and partnerships; etc. Finally we can observe a concentrated oligopolistic behavior which highlights the existence of interdependence relationships among players.</p><p>Some of these hypotheses were confirmed and nuanced, but the most important conclusion is that the behavior companies, markets and competition at the microeconomic level, are complex and evolves over time.</p></div>","PeriodicalId":100390,"journal":{"name":"Economía Informa","volume":"400 ","pages":"Pages 3-23"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.ecin.2016.09.002","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85800965","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
