Why Don’t People Pay Attention? Endogenous Sticky Information in a DSGE Model
Building on the models of sticky information, we endogenize the probability of obtaining new information by introducing a switching mechanism allowing agents to choose between costly rational expectations and costless expectations under sticky information. Thereby, the share of agents with rational expectations becomes endogenous and timevarying. While central results of sticky information models are retained, we find that the share of rational expectations is positively correlated with the variance of the variable forecasted, providing a link to models of near-rationality. Output expectations in our model are generally more rational than inflation expectations, but the share of rational inflation expectations increases with a rising variance of the interest rate. With regard to optimal monetary policy, we find that the Taylor principle provides a necessary and sufficient condition for the determinacy of the model. However, output and inflation stability are optimized if the central bank does not react too strongly to inflation, but rather also targets the output gap with a relatively large coefficient in the Taylor rule

A new anthracycline regimen for prolymphocytic leukemia? Study of a case report with flow cytometric implications.
A case of prolymphocytic leukemia (PL) is reported, which showed a good response to a new antiblastic schedule (4-epidoxorubicin-asparaginase-dexamethasone) in spite of the resistance to other chemotherapy regimens. However during the course of the disease it was possible to observe the terminal appearance of a small aneuploid cell population in the peripheral blood of the patient and, in the same time, the clinical condition deteriorated considerably. The significance of this neoplastic progression and the pros and cons of aggressive chemotherapy regimens remain to be carefully evaluated in PL and related disorders.
