Régimen político y democracia: conflicto constitucional en el pluralismo incompleto

Two constitutional features frame Mexico’s arrival to democracy: the creation of credible electoral institutions and the preservation of rules corresponding to the authoritarian regime inherited from the decade of the ‘30s in the twentieth century. These two sets of rules clash with each other, a fact which explains the low levels of democratic governance and the low quality of legislation and public policies. The political debate over this contradiction seems to have reached the lowest point and several different alternatives have been formulated to break the deadlock; nevertheless, the necessary political agreements that may clearly define a political path have not been reached. The article describes these processes and lays out the alternatives in dispute as well as possible outcomes in the near future.     

Can corruption constrain the size of governments?

This paper analyzes the relationship between government size and the level of corruption. We propose a theoretical model where production decisions and corrupt behavior are endogenously determined. We model corruption assuming production in the formal sector is regulated by public officials who can use their public power for private gain. In this context, the underground economy emerges as an outside option that allows entrepreneurs to avoid dealing with bureaucrats. The fact that investments in the informal sector may influence public finances, introduces the possibility of multiple equilibria with different levels of corruption. Consistent with previous theoretical works and recent empirical evidence, we find out that corruption and the shadow economy are complements as they positively correlate across equilibria, which implies that corruption may limit the size of the public sector.     

Alleged Biological Father Incest: A Forensic Approach

Paternal incest is one of the most serious forms of intrafamilial sexual abuse with clinical, social, and legal relevance. A retrospective study was performed, based on forensic reports and judicial decisions of alleged cases of biological paternal incest of victims under 18 years old (n = 215) from 2003 to 2008. Results highlight that in a relevant number of cases: victims were female; the abuse begun at an early age with reiteration; the alleged perpetrator presented a history of sexual crimes against children; sexual practices were physically poorly intrusive, which associated with a forensic medical evaluation performed more than 72 h after the abuse, explain partially the absence of physical injuries or other evidence—these last aspects are different from extrafamilial cases. In conclusion, observations about paternal incest are likely to exacerbate the psychosocial consequences of the abuse and may explain the difficulty and delay in detect and disclose these cases. Few cases were legally prosecuted and convicted.     

Is There an Informative Effect of Law? An Experimental Test

Debates on how the law affects citizens' behaviour have traditionally focused on two mechanisms: deterrence and perceptions of legitimacy. In recent years, some scholars have suggested that the law may also affect compliance through expressive mechanisms that reveal information about the world (for example, by eliciting the risks associated with a particular behaviour). Dharmapala and McAdams have called this the informative effect of law. However, to date very little empirical evidence of the existence of such an effect has emerged. In this article, we present the results of an experiment that tests for three different hypotheses as to how this effect may be produced. Our findings show that legislators' sincerity or their access to expert knowledge is not sufficient to produce information effects. Instead, we suggest an ‘asymmetry’ hypothesis: the fact that a law is passed or rejected has an asymmetrical information effect on subjects' risk perceptions.     

Experimental forensic scenes for the characterization of ground-penetrating radar wave response

Over the last few decades, the use of non-intrusive geophysical techniques, which allows for coverage of an entire crime scene in a reasonable amount of time, in forensic investigation has increased. In this study, we analyze the effectiveness of ground-penetrating radar (GPR) in forensics. Experimental scenes were simulated and some of the most commonly buried items in actual crime scenes were introduced, such as bone remains, guns and drug caches. Later, a GPR survey was conducted on the experimental grids with a 500 MHz antenna. The final purpose was to characterize the radar wave response expected for each set of remains to assist with its identification in later actual investigations. The results collected provided promising information that can be used when surveying real cases. Nevertheless, there were some interpretational difficulties regarding the sizes of the items and the electromagnetic properties of the materials. For these cases, finite-difference time-domain modeling was employed to achieve an advanced interpretation of the field data. The simulated models used were built from accurate geometric data provided by photogrammetric methods, which replicate the experimental scenes in fine detail. Furthermore, this approach allowed for the simulation of more realistic models, and the synthetic data obtained provided valuable information for assisting in the interpretation of field data. As a result of this work, it was concluded that GPR can be an effective tool when searching for a variety of materials during a crime scene investigation.     

Market Structure and R∧D Joint Ventures: The Case of Product Innovations

Departing from the received fact that research joint venture agreements are allowed on the grounds of a permissive ruling, we study what conditions are necessary for venture partners to carry on RD cooperation to the marketing stage. We treat the case of product innovations exploitable with different usages in unconnected markets. Two main results appear: firms always have incentives for a distribution of varieties, but not always agree on the distribution of products. The condition for the last result to happen gives a useful rule for antitrust authorities relating the degree of sustitutability across varieties and the relative profitability of the markets.     

Deteriorating public and private sector relations in Central America

The Central American countries are divided by profound political differences. Yet surprising similarities exist in the changing relations between the public and private sectors. Throughout the region, public and private sectors lock into a vicious circle. The inability of the state to provide order and social harmony creates disincentives for the private sector to invest or even to continue existing levels of production. The government responds by increasing its responsibilities at the expense of the private sector. In doing so it assumes risks the private sector refuses, but further alienates the private sector nonetheless.
