Measuring welfare losses from interruption and pricing as responses to water shortages: an application to the case of Seville

Supply cuts and pricing policies can be used to ration water. The appropriateness of a given policy depends on the losses in social welfare which it generates. We find some drawbacks with the only method in the previous literature which deals with the issue of measuring welfare losses under supply cuts. We propose an alternative method. We compare the welfare losses under supply cuts and a pricing policy during the drought period of 1992–1996 in Seville, Spain, using both methods, and find that the results vary widely from one method to the other.      

The Validity of Gibrat’s Law: Evidence from Ecuadorian Service SMEs

The objective of this research is to analyze the relationship between size and growth through the validation of Gibrat's law. A sample of 17,082 Ecuadorian companies in the service sector is used for the period 2010–2015. The estimation method used is that of quantile regression for panel data; the results suggest that small companies grow faster than their larger counterparts. The results show that the growth, measured through sales and employment, of SMEs in the service sector in Ecuador is not independent of firm size and therefore does not correspond to a random process.     

Growth determinants in entrepreneurship: A longitudinal study of Spanish technology-based university spin-offs

The study explores whether the university origin of a technology-based firm conditions its growth in terms of both sales and employment. The small firm size of a significant percentage of technology-based university spin-offs (T-USOs) puts into question the policies geared towards promoting university entrepreneurship. A sample of 340 Spanish technology-based firms (219 T-USOs and 121 T-non-USOs) was constructed by using the non-parametric technique of propensity score matching and the data refer to the period 2001–2010. Applying panel data methodology, we find that the T-USOs outperform the T-non-USOs. Therefore, the need for support of university-based entrepreneurship by governments and by the universities is justified, because in this way, they are promoting economic growth and social development. By launching T-USOs, universities not only contribute to the economic growth but also to the internationalisation of the economy, as T-USOs show a more international orientation. In addition, the results lead us to emphasise the need to customise university policies aimed at promoting the growth of T-USOs. Given that the study is focused on a ‘moderate innovator’ country, the conclusions and proposals of this paper may be extrapolated to other countries with similar innovation and entrepreneurial ecosystems, namely the Mediterranean and Latin American countries.     

Socially responsible consumption: an application in Colombia

This study constructs a measurement scale for Socially Responsible Consumption in the particular context of Colombia. It uses a mixed qualitative and quantitative methodological approach, beginning with four focus groups and ending with a quantitative validation exercise employing Exploratory Factor Analysis. The result is a Socially Responsible Consumption measurement scale consisting of four dimensions that reflect paradigms found in the existing literature. These are, however, expressed differently in Colombia. In particular, Socially Responsible Consumption involves consumer behavior that favors corporate social responsibility practices and the rational consumption of resources and products while recognizing the importance of maintaining a healthy lifestyle through healthcare.     

He Who Counts Elects: Economic Elites,Political Elites,and Electoral Fraud

What determines the extent of electoral fraud? This paper constructs a model of the tradeoff between fraud and policy concessions (public good provision) which also incorporates the strength of the state. In addition, we parameterize the extent to which economic elites (to whom fraud is costly) and political elites (to whom fraud is advantageous) “overlap.” The model predicts that fraud will be lower and public good provision higher when land inequality is higher, the overlap between elites lower, and the strength of the state higher. We test these predictions using a unique, municipal‐level dataset from Colombia's 1922 Presidential elections. We find empirical support for all the predictions of the model.     

Kicking Away the Ladder,Too: Inside Central Banks

Central banks are evolving institutions. In developed countries, particularly in Britain, central banks were used as instruments of the state to finance government and to promote economic development. However, once they went up the economic ladder, advanced economies kicked it to preclude developing countries from climbing it, too. It is in this context that the modern independent central bank, concerned with inflation targeting alone, which harkens back to the Victorian era, should be interpreted. This paper analyzes the recent evolution of the Argentine central bank in this broad historical perspective.     

Store brand and national brand promotion attitudes antecedents

Retailers compete against national manufacturers by launching store brands. National manufactures regularly use brand promotions to fight store brands back. The purpose of this article is to find out whether attitudes toward national brand promotions and store brands have similar or different conceptual antecedents. The study presents and tests a model of the effects of shoppers´ characteristics (price and non-price-related) on attitudes toward store brand and national brand promotions. The results support that constructs relating to price impact both store brand attitude and national brand promotion attitude, but the strength of some of these relationships differ. Other shopper characteristics like brand loyalty and store loyalty, have similar negative and positive effects, respectively. These slight differences suggest that promotions of national brands might be a good tool for fighting back store brands, but manufacturers need to design and target these promotions carefully in order to avoid head-to-head competition.
