Informality and Profitability: Evidence from a New Firm Survey in Ecuador

This article estimates the impact of informality on profits using a new survey administered to 1,200 firms with less than 50 employees in four cities in Ecuador. The article proposes a novel definition of informality which explicitly recognises that most firms comply with some regulations but not others. Accounting for firm selection and controlling for a large set of firm, owner and location characteristics, the article finds that more formal firms tend to be more profitable and have higher output per worker. This impact operates, inter alia, through improved access to credit and higher sales through issuance of tax receipts.     

Exploring Perceptions of Portuguese Police about Human Trafficking Victims and Perpetrators

Breaking the Law to Ensure Order: The Case of Tijuana (2007–2012)

This paper explores how state agents and civilians justify human rights violations when the military perform police tasks. Based on a set of interviews and documents, it analyses the actions of the armed forces and the police during a military-led operation that targeted drug trafficking organisations in Tijuana. In a context of limited civilian control over the armed forces and the police, the paper identifies two discourses that supported the illegal action of state agents: the construction of a foreign other who does not belong to society and the need to use violence to accomplish a greater good.

Precarious employment conditions affect work content in education and social work: results of work analyses

Work content is adversely affected by precarious employment conditions, with consequences for workers and clients/customers. Three examples are taken from professions involving long-term relations between workers and clients. Adult education teachers hired on short-term contracts to teach primarily immigrant populations prepare their courses under less favorable conditions than regular teachers and their employment context foments hostility among teachers. Special education technicians are hired on a seasonal basis which interferes with their ability to coordinate and plan their efforts in collaboration with teachers. Workers in shelters for women suffering conjugal violence who were hired on a casual or on-call basis were unable to follow up with women they helped during their shifts and more rarely engaged in one-on-one counseling. Precarious work contracts can affect mental health not only through employment insecurity but also through negative effects on the ability to do one's job and take pride in one's work, as well as weakening the interpersonal relationships on which successful, productive work depends.     

Chemistry in crime investigation: sodium percarbonate effects on bloodstains detection

Chemistry plays a leading role in crime investigation. In the study of bloodstains, chemical reactions provide the means for the detection. All these procedures have been thoroughly studied. However, recently, a new source of error has been found: washing stains with "active oxygen" detergents abrogates presumptive and human hemoglobin tests for bloodstains (although visible). The aim of this investigation was to evaluate the ability of pure sodium percarbonate-main component of detergents-to abrogate presumptive and human hemoglobin tests. Then, a solution to this problem could be found. The results demonstrate that pure sodium percarbonate-itself-is able to abrogate all tests, as well as the different degrees to which each of them is affected by the product. Consequently, faced with a stain of bloody appearance, even the preliminary tests are negative; it is advisable to analyze the DNA. Otherwise, the opportunity of obtaining valuable information is lost.     

Central Bank Independence in the World: A New Data Set

This article introduces the most comprehensive dataset on de jure central bank independence (CBI), including yearly data from 182 countries between 1970 and 2012. The dataset identifies statutory reforms affecting CBI, their direction, and the attributes necessary to build the Cukierman, Webb and Neyapty index. Previous datasets focused on developed countries, and included non-representative samples of developing countries. This dataset’s substantially broader coverage has important implications. First, it challenges the conventional wisdom about central bank reforms in the world, revealing CBI increases and restrictions in decades and regions previously considered barely affected by reforms. Second, the inclusion of almost 100 countries usually overlooked in previous studies suggests that the sample selection may have substantially affected results. Simple analyses show that the associations between CBI and inflation, unemployment or growth are very sensitive to sample selection. Finally, the dataset identifies numerous CBI decreases (restrictions), whereas previous datasets mostly look at CBI increases. These data’s coverage not only allows researchers to test competing explanations of the determinants and effects of CBI in a global sample, but it also provides a useful instrument for cross-national studies in diverse fields, such as liberalization, diffusion, political institutions, democratization, or responses to financial crises.
