FOREIGN MONOPOLIES AND TARIFF AGREEMENTS UNDER INTEGRATED MARKETS
In this paper the optimal policy and the stability of a tariff agreement among the importers of a monopolized good that is sold in an integrated market are studied. To analyze the stability, the tariff agreement formation is modelled as a two-stage game. In the first stage each importer decides whether or not to sign the agreement and in the second stage the signatories and non-signatories choose their tariff whereas the monopoly chooses the quantity or the price. The findings show that the optimal policy of the importers depends on which strategic variable is selected by the monopolist but that, on the contrary, this decision has no effects on the level of cooperation that can be reached by a self-enforcing tariff agreement that, in any case, is very low.foreign monopolies, self-enforcing tariff agreements, integrated markets, rent-shifting hypothesis, prices versus quantities
NONLINEAR MONETARY POLICY RULES: SOME NEW EVIDENCE FOR THE US
This paper dreives optimal monetary policy rules in setups where certainty equivalence does not hold because either central bank preferences are not quadratic, and/or the aggregate supply relation is nonlinear. Analytical results show that these features lead to sign and size aymmetries, and nonlinearities in the policy rule. Reduced-form estimates indicate that US monetary policy can be characterized by a nonlinear policy rule after 1983, but not before 1979. This finding is consistent with the view that the Fed`s inflation preferences during the Volcker-Greenspan regime differ considerably from the ones during the Burns-Miller regime.

Rapid onset of hypercalcemia from high-grade lymphoma in the setting of HIV-related immune reconstitution inflammatory syndrome.
Hypercalcemia in HIV patients has been previously reported, but 1,25-(OH)2 vitamin D-mediated hypercalcemia, due to increased activity of extrarenal 1-alpha hydroxylase, is rarely described with HIV-related infections or malignancies. We describe a case of 1,25-(OH)2 vitamin D-mediated hypercalcemia in a patient presenting with progressive cognitive decline and weakness. Initial evaluation revealed a new diagnosis of HIV, for which he was started on antiretroviral therapy (ART). He was also noted to have mild asymptomatic hypocalcemia, likely from his acute illness and malnutrition, which was not further investigated at the time. While the patient's mental status initially improved with ART, he became progressively delirious and was found to be hypercalcemic approximately 4âŻweeks after the initiation of ART. Possible etiologies for hypercalcemia were vigorously evaluated, including granulomatous disease, infection, and malignancy, in the setting of suspected immune reconstitution inflammatory syndrome (IRIS), due to recent initiation of ART. Infectious workup was unrevealing, but computed tomography (CT) of the chest, abdomen, and pelvis revealed new extensive diffuse lymphadenopathy and hepatomegaly, not present on admission studies. Cytology and flow cytometry of a liver biopsy specimen revealed CD10 positive high-grade B-cell lymphoma. Chemotherapy was not pursued due to poor performance status. Over the next week, spontaneous tumor lysis developed, and the patient expired. Postmortem, his 1,25-(OH)2 vitamin D level returned as markedly elevated. Immunohistochemical staining of his liver biopsy tissue showed strong expression of CYP27B1. 1,25-(OH)2 vitamin D-mediated hypercalcemia is uncommon in a patient with newly diagnosed HIV and, in this case, was likely due to IRIS unmasking an underlying high-grade lymphoma and restoration of immune function (including T-cells and cytokine production). This case emphasizes the importance of including aggressive lymphomas, capable of progressing over days to weeks, in the evaluation of hypercalcemia in HIV patients at risk for developing IRIS and the rapid dynamic changes in mineral homeostasis that can occur with such an aggressive tumor in an immunocompromised host

- DUOPOLY PRICE COMMUNICATION
We investigate the role of price communication in imperfect information environments by setting up a dynamic differentiated duopoly where actions are not observable and where firms decide, before pricing, whether to communicate their choices to the rivals. When firms play simultaneously in the pricing stages, communication across them is a dominant strategy allowing firms to coordinate prices, thus reducing competition. However, when communication takes place within pricing stages, this meaning that firms are given the opportunity to choose roles, the above firms coordination in prices is mitigated. This is because of the existence of a second mover advantage effect. Communication by the leader acts as a pre-commitment device to a price umbrella that the follower will undercut. As a result, we end up with a more competitive situation although price levels will not go down to those without communication.commitment, price communication
