Y-chromosome STR-haplotype typing in El Salvador

Eight Y-chromosome STRs were investigated in a male population sample from El Salvador. Complete Y-chromosomal STRs haplotypes were obtained in 121 individuals, among which 107 different haplotypes were observed. The two most common haplotypes were shared by approximately 4% of the sample, while 100 haplotypes were unique. The gene diversity was 0.9883 and the discrimination capacity was 0.8926. The combined Y-chromosome STR polymorphisms provide a powerful discrimination tool for routine forensic applications.     

Early Childhood Predictors of Teen Dating Violence Involvement at Age 17

The distal relationship between risk factors in childhood and subsequent dating violence in late adolescence has not often been explored using longitudinal data. This study aims to shed light on the problem of dating violence by examining children’s backgrounds at age 7 and the link to the future involvement in dating violence at age 17 using the first and seventh waves of the Zurich Project on the Social Development from Childhood to Adulthood (z-proso, n?=?644). The sample consists of 644 multiethnic adolescents (57.14% female, M?=?17.47, SD?=?0.37), mainly Swiss-born (90%), though more than half of their parents (60%) were born in another country. A latent class analysis was applied to identify three different profiles (a) zero (or minimal) involvement in teen dating violence, (b) perpetrators/victims of controlling behaviors, and (c) perpetrators/victims of controlling behaviors and of physical violence. Participants who were corporally punished and/or victims of bullying at age 7 were significantly more likely to belong to the controlling and physical violence profile than children in the non-violent class. These results suggest a certain chronicity of the effects of violent experiences in early childhood on the patterns of romantic relationships at 17 years old.

     

Elections and Deceptions: An Experimental Study on the Behavioral Effects of Democracy

Traditionally, the virtue of democratic elections has been seen in their role as means of screening and sanctioning shirking public officials. This article proposes a novel rationale for elections and political campaigns considering that candidates incur psychological costs of lying, in particular from breaking campaign promises. These nonpecuniary costs imply that campaigns influence subsequent behavior, even in the absence of reputational or image concerns. Our lab experiments reveal that promises are more than cheap talk. They influence the behavior of both voters and their representatives. We observe that the electorate is better off when their leaders are elected democratically rather than being appointed exogenously—but only in the presence of electoral campaigns. In addition, we find that representatives are more likely to serve the public interest when their approval rates are high. Altogether, our results suggest that elections and campaigns confer important benefits beyond their screening and sanctioning functions.     

Después del consenso: el liberalismo en México (1990-2012)

This article explores the renewal of liberalism in Mexico over the last two decades. It argues that after the long period of one-party hegemonic rule, intellectuals have embraced many of liberalism’s tenets in public debates, such as economic and institutional reform, the defense of individual rights and freedom of expression, etc. It argues that the end of authoritarian rule made this renewal possible and attempts to account for key factors that unite intellectuals from very different ideological backgrounds.     

Openness and the International allocation of foreign direct investment

This paper develops an ordinal index to measure the openness of FDI policy regimes for individual countries. There has been a generalised increase in the index between 1990 and 2002. The most important determinants of variations in FDI flows across countries and over time are country size, the level of educational achievement, and growth. The openness index is positively associated with FDI flows, but its explanatory power is low. Liberalising approval procedures and lifting requirements that foreign companies enter into joint ventures with domestic firms encourage FDI. We conclude that the openness of the FDI regime operates as a factor enabling FDI, but that location advantages are paramount in determining the international allocation of FDI. We also turn the question around and ask what countries are more likely to impose restrictions on FDI. We find that lower levels of education and larger domestic markets are associated with greater restrictions on FDI. In addition, there is some evidence that better institutions are associated with lower FDI restrictions.     

A Macro–Micro Analysis of the Effects of Electricity Reform in Senegal on Poverty and Distribution

This paper uses a computable general equilibrium (CGE) macro–micro model to explore the distributional effects of price reform in the electricity sector of Senegal. In the first part of the paper we analyse the distribution of electricity in Senegal by income quintiles, between 1995 and 2001. The analysis demonstrates that poor and rural households are not the main beneficiaries of the expanded network. The results of the CGE model show that direct price effects are weaker than general equilibrium effects on poverty and inequality. Moreover, compensatory policies tested can help attenuate some adverse effects.     

Colonisation,Institutions and Development: New Evidence

This article analyses current attempts to identify the factors underlying long-term economic growth. The author criticises some of the arguments and historical evidence on which the two main explanations that dominate recent literature are based: the institutional approach and the approach focusing on the importance of geographical factors. Using an approach which is deliberately eclectic, the author considers the role of geography, international trade, human capital and institutional quality in explaining development. A new estimation is carried out through Two Stages Least Squares (TSLS) with instrumental variables. The results of the empirical model confirm the central role of institutions in long-term economic growth. However, certain geographical conditions also seem to have influenced countries' chances of progress. The human capital is a less robust factor in explaining economic growth and trade openness does not seem significant in any estimation. Nevertheless, several questions remain to be answered, suggesting that cross-country estimations need to be complemented with a deeper historical analysis.
