I develop a theory of stock-based compensation contracts for the chief executive officers (CEOs) of firms and confront the theoretical predictions with recent CEO compensation data. The model characterizes the optimal contract for a CEO whose reputation evolves as signals of the executive's ability are observed by shareholders. Using various proxies for CEO(More)
Alkaline secretion (AS) was sought in vivo in the rabbit and opossum esophagus, using a recirculated unbuffered saline solution and pH stat technique. The rabbit and opossum were used because both have stratified squamous epithelium; however, only the opossum has, in addition, an extensive network of submucosal glands. Mean basal AS in the rabbit was 0.02(More)

We report the first synthesis of polyimide aerogels cross-linked through a polyhedral oligomeric silsesquioxane, octa(aminophenyl)silsesquioxane (OAPS). Gels formed from polyamic acid solutions of 3,3',4,4'-biphenyltetracarboxylic dianhydride (BPDA), bisaniline-p-xylidene (BAX) and OAPS were chemically imidized and dried using supercritical CO(2) extraction(More)
The effects of cholinergic and adrenergic agonists and antagonists on esophageal bicarbonate secretion in the opossum were studied in vivo using a recirculated unbuffered saline solution and pH stat technique. The basal rate of secretion was 0.28 +/- 0.02 mumol.h-1.cm-2, and this increased in a dose-dependent manner by intravenous administration of(More)

Little evidence exists that ¢rms index executive compensation to remove the in£uence of marketwide factors. We argue that executives can, in principle, replicate such indexation in their private portfolios. In support, we ¢nd that market risk has little e¡ect on the use of stock-based pay for the average executive. But executives'ability to(More)
Combinations of rigid and flexible aromatic diamines were used to tailor the properties of octa(aminophenyl)-silsesquioxane (OAPS) cross-linked polyimide aerogels. 2,2'-Dimethylbenzidine (DMBZ) or p-phenylenediamine (PPDA) was used in combination with the more-flexible diamine, 4,4'-oxydianiline (ODA). The amount of rigid diamine was varied from 0% to 100%(More)
