Effort,Technology and the Efficiency of Agricultural Cooperatives

The inefficiency of cooperative agriculture relative to private farms is often attributed to difficulties in monitoring or poor incentives. We develop a model to show that, in technologies with numerous sequential steps, even small shortfalls in worker effort can result in large output declines. Using data on cooperative and private farms in El Salvador, we find greater shortfalls in efficiency between cooperatives and private farms, as well as among cooperatives, for coffee, a crop requiring numerous steps in its cultivation, than for maize and sugar, which require fewer steps. Thus the undersupply of effort in cooperatives may be less than differences in productivity suggest, and cooperative agriculture is most likely to be successful where production does not involve many sequential steps.     

¿Por qué prevalece el estado de derecho? una aproximación comparada a las explicaciones centradas en la cultura de la legalidad

The objective of this paper is to analyze the relation between the concept of the Rule of Law and the culture of legality from a compared approach in order to establish the scope and limitations of explanations that are based in cultural factors. More specifically, we are interested in comparing the scope and limitations of culture-based explanations on why the Rule of Law prevails in certain countries: these explanations are centered in the construction of wide agreements between social actors and the control by civil society. Also we consider equally important the comparing of different definitions of culture of legality and the strategies and instruments that allow its construction. For this purpose we will center, specially, in the experiences of Hong Kong, Palermo and Bogotá.     

Economic performance and turnout at national and local elections

This paper analyzes the impact of economic performance on voter turnout. We estimate an economic turnout model in which local economic variables are included in quadratic form, so that non-linear effects can be taken into account. We use panel datasets covering municipalities, from 1979 to 2005, and cross-sections of parishes (freguesias) to analyze the determinants of turnout at Portuguese municipal and legislative elections. The empirical results indicate that the performance of the national economy is important only in legislative elections and that the regional and local unemployment rates tend to have non-linear relationships to turnout. The results obtained for Flemish municipalities also provide evidence in favor of a non-linear effect of unemployment on turnout.     

On the Relationship between Violent Conflict and Wages in Colombia

We analyse how forced displacements caused by violent conflict are related to the wages of workers in Colombia. Using data from the Quality of Life Survey (2011–2014), we analyse the differences in wages between those forced by violence to move to other regions, and those who moved for other reasons. We apply Propensity Score Matching techniques to compare workers from the two groups, finding that forced displacement is related to decreases of between 10 and 29 per cent in the wages of males, and between 18 and 37 per cent in the wages of females, relative to their counterparts. Thus, forced displacements are related to poorer labour market outcomes in terms of wages.     

Demobilization of Paramilitaries in Colombia: Transformation or Transition?

Historically, Disarmament, Demobilization, and Reinsertion (DDR) has provided a useful means to terminate conflicts. Since being catapulted to office in August 2002 with 53 percent of the vote of 46.45 percent of the voters, ¹ 1. IFES Election Guide, available at (http://www.electionguide.org/results.php?ID=1011). Colombian President Álvaro Uribe has vigorously pursued a demobilization program, both individual and collective. However, despite the fact that over 40,000 combatants have demobilized under these programs, evidence is growing that this latest round of Colombian DDR is merely transitioning, rather than terminating, violence in that Andean country.

The black soldier-fly, Hermetia illucens (Diptera, Stratiomyidae), used to estimate the postmortem interval in a case in Amapá State, Brazil

The black soldier-fly (Hermetia illucens) is a generalist detritivore which is commonly present in corpses in later stages of decomposition and may be useful in forensic entomology. This paper describes the estimation of the postmortem interval (PMI) based on the life cycle of the black soldier-fly in a case in northern Brazil. A male child was abducted from his home and 42 days later his corpse was found in an advanced stage of decay. Two black soldier-fly larvae were found associated with the body. The larvae emerged as adults after 25-26 days. Considering the development cycle of H. illucens, the date of oviposition was estimated as 24-25 days after abduction. Since H. illucens usually (but not always) colonizes corpses in more advanced stages of decay, this estimate is consistent with the hypothesis that the child was killed immediately after abduction.     

Coprophanaeus lancifer (Linnaeus, 1767) (Coleoptera, Scarabaeidae) activity moves a man-size pig carcass: relevant data for forensic taphonomy

Taphonomy is the study of many variables involving decomposition, preservation, dispersal, erosion, burial or exposition of dead organisms. Forensic Taphonomy examines how biotic or abiotic variables can change evidences in legal investigations. Many insects are closely associated with decomposition processes. The scavenger dung-beetle, Coprophanaeus lancifer (Linnaeus, 1767), may be important biotaphonomically in the decomposition process of carcasses. Man-size pig carcasses were used as models to examine the decomposition process in the Adolpho Ducke Forest Reserve in central Amazonia. The scavenger dung-beetle has great potential in decomposition and production of post-mortem injuries, including dismemberment and the removal of soil beneath the carcass thereby causing a change in its position.
