Summary. In this paper we study the real and financial effects of insider trading in a Static, Kyle-type model. In our model the insider
is also the manager of the firm. Hence the insider chooses both the amount of the real output to be produced and the amount
of the stock of the firm to trade. The aim of the paper is to study the relationship between financial decisions and real
decisions. In particular, we examine how insider trading on the stock market affects the real output and price and how the
real decision making affects the financial variables, such as the extent of insider trading, stock prices, and the stock pricing
rule of the market maker. In the model, the market maker observes two correlated signals: the total order flow and the market
price of the real good. We study the informativeness of the stock price and the effects on insider's profits. We also construct
a compensation scheme that aligns the interests of the insider and the firm. Finally, we generalize the pricing rule set up
by a competitive market maker and analyze the comparative statics of the model.

Uncertainty and the size distribution of rewards from innovation 总被引:3,自引:1,他引:3
Previous research has shown that the distribution of profit outcomes from technological innovations is highly skew. This
paper builds upon those detailed findings to ask: what stochastic processes can plausibly be inferred to have generated the
observed distributions? After reviewing the evidence, this paper reports on several stochastic model simulations, including
a pure Gibrat random walk with monthly changes approximating those observed for high-technology startup company stocks and
a more richly specified model blending internal and external market uncertainties. The most highly specified simulations suggest
that the set of profit potentials tapped by innovators is itself skew-distributed and that the number of entrants into innovation
races is more likely to be independent of market size than stochastically dependent upon it. 相似文献

Gasoline divorcement regulations restrict the integration of gasoline refiners and retailers. Theoretically, vertical integration can harm competition, making it possible that divorcement policies could increase welfare; alternatively, these policies may reduce welfare by sacrificing efficiencies. This paper attempts to differentiate between these possibilities by estimating a reduced form equation for the real retail price of unleaded regular gasoline. I find that divorcement regulations raise the price of gasoline by about 2.6¢ per gallon, reducing consumers surplus by over $100 million annually. This finding suggests that current proposals to further separate gasoline retailing from refining will be harmful to gasoline consumers. 相似文献

The recent growth of interest in voluntary benefits has coincided with a decline in resources available to administer benefit programs. Fortunately, technology offers employers a solution to this resources dilemma in the form of portals, which allow employers to provide choice and access to voluntary benefits without concerns about increasing the workload for the benefits staff and without causing confusion among employees. 相似文献

The aim of evidence-based guidelines is primarily to improve patient outcomes without adding to the existing cost of care because both payers and policymakers want to identify health care costs that do not result in benefit to the patient. The purpose of the reported project was to generate a practice guideline for the treatment of uncomplicated acute cystitis in a female population, to determine the extent to which the guideline would be used by providers and to measure the cost and quality of outcomes from its use. A retrospective chart review was used to gather pre-guideline practice and cost data. Measurements included the type, frequency, and duration of antibiotic therapy and the use of urine cultures and both complications and routine followup visits. The implementation of an outpatient practice guideline resulted in a significant change in antibiotic prescribing and a trend toward a change in ordering cultures and clinic followup. There was also a significant decrease in treatment costs. 相似文献
