We report a case of a nine-year old boy with vomiting, abdominal pain and fever, who underwent surgery with a diagnosis of appendicitis in Mendoza and from whom a Shiga toxin-producing Escherichia coli (STEC) O127:H21 strain was recovered. Forty-eight hours after surgery he presented bilious vomiting and two episodes of intestinal bleeding. Laboratory findings included: hematocrit, 35%; blood u...

The capacity of Shiga toxigenic Escherichia coli (STEC) to adhere to the intestinal mucosa undoubtedly contributes to pathogenesis of human disease. The majority of STEC strains isolated from severe cases produce attaching and effacing lesions on the intestinal mucosa, a property mediated by the locus of enterocyte effacement (LEE) pathogenicity island. This element is not essential for pathoge...

How are the optimal tax and debt policies affected if government can default on its debt? We address this question from a normative perspective in an economy with noncontingent debt, domestic default, labor taxes. On one hand, prevents incurring future distortions associated servicing debt. other risk gives rise to endogenous credit limits that hinder government's ability smooth characterize fi...

This paper investigates analytically the welfare effects of black-market activities that firms undertake to evade taxes. The desirability of a black market is linked to the attributes of the goods supplied by blackmarket firms. The analysis identifies cases where a black market reduces (increases) the distortionary impact of taxation on the allocation of resources across the goods that the gove...

We generalize the Diamond–Mirrlees production efficiency theorem, that there should be no taxes on sectors producing pure intermediate goods, to an environment with political economy constraints. In our economy, allocations and taxation are decided by self-interested politicians without the power to commit to future policies. The Diamond–Mirrlees production efficiency result holds even when pol...
