This article analyzes whether publicly traded firms price differentlyfrom privately held firms in the product markets. Our empiricalevidence shows that, in the U.S. newspaper industry, firms increasetheir prices when their ownership structure changes from privateto public. The effects are robust and significant. A plausibleexplanation is that private owners enjoy more freedom than publicmanagers to expand circulation and distort content, pursuingthe consumption of nonpecuniary benefits of control. Additionalevidence is consistent with this interpretation. Public newspapersshow lower prices when insiders' ownership participation ishigher. Moreover, private newspapers appear more likely thanpublic newspapers to endorse a candidate during presidentialcampaigns. To my knowledge there are no previous studies comparingpricing by private and public companies. 相似文献

In multiparty legislatures, the largest party or coalition may fall short of controlling a majority of plenary seats. However, plurality‐led congresses generally endow the largest parties with extensive agenda‐setting prerogatives, even when plenary majorities are lacking. In this article, we present a model and compelling evidence describing changes in the strategic behavior of committee chairs when majority control is lost. Using a dataset that includes all the bills proposed to the Argentine House in the last 25 years, we estimate success in committee in majority‐ and plurality‐led congresses. We provide extensive evidence that the loss of majority control reduces the importance of the median voter of the plurality party while improving the success of the median committee voter. 相似文献

Abstract: Supine hypotensive syndrome is characterized by severe supine hypotension in late pregnancy, whose clinical presentation ranges from minimal cardiovascular alterations to severe shock, resulting from inferior vena cava compression by gravid uterus. We report a case of a 41‐year‐old 39‐week‐pregnant woman found dead supine. Autopsy revealed the following: cyanosis of the limbs; congestion of the jugular and subclavian veins; abundant abdominal subcutaneous fatty tissue; uterus displacing intestine and diaphragm; collapsed inferior vena cava; both femoral veins dilated and filled with blood; edematous and congested lungs; and placenta 790 g, fetus 3475 g, amniotic fluid 800 cm3. The diagnosis of supine hypotensive syndrome as the probable cause of death is supported by the position of the body and autopsy findings. This syndrome can be considered as the first stage of the physio‐pathological mechanism that led to death in the case presented herein and should be considered by pathologists as a cause of sudden death. 相似文献

The present study aimed determines lead (Pb), antimony (Sb) and barium (Ba) as the major elements present in GSR in the environmental air of the Ballistics Laboratory of the S?o Paulo Criminalistics Institute (I.C.-S.P.), S?o Paulo, SP, Brazil. Micro environmental monitors (mini samplers) were located at selected places. The PM(2.5) fraction of this airborne was collected in, previously weighted filters, and analyzed by sector field inductively coupled plasma mass spectrometer (SF-HR-ICP-MS). The higher values of the airborne lead, antimony and barium, were found at the firing range (lead (Pb): 58.9 μg/m(3); barium (Ba): 6.9 μg/m(3); antimony (Sb): 7.3 μg/m(3)). The mean value of the airborne in this room during 6 monitored days was Pb: 23.1 μg/m(3); Ba: 2.2 μg/m(3); Sb: 1.5 μg/m(3). In the water tank room, the air did not show levels above the limits of concern. In general the airborne lead changed from day to day, but the barium and antimony remained constant. Despite of that, the obtained values suggest that the workers may be exposed to airborne lead concentration that can result in an unhealthy environment and could increase the risk of chronic intoxication. 相似文献
