There is little question that new product innovation is a cornerstone to firm success. Particularly in technologically dynamic markets like personal computers, new products are central to long-term financial performance. However, exactly how new product introductions influence firm value is less...

We empirically study the dynamics of R&D productivity by firm size over an industry's life cycle. To do this, we examine the relationship between R&D expenditures, firm size, and new product introductions at the firm level in the personal computer industry. In general, we find the following. (1)...

An optimal control model of global warming is presented and analyzed. The model has two state variables, representing the anthropogenic concentration of greenhouse gases in the atmosphere and the temperature increase due to the greenhouse gas concentration. The state equation for greenhouse gas...

A differential game of global warming is offered. The game involves individual country social utility functions that balance gains from GHG emissions with damages due to global warming. Two state variables are involved, the concentration of anthropogenic GHG in the atmosphere, and the increase...

Advertising is tied to global warming through an endogenous growth model. The model allows for the possibility that the environment can become a source rather than a sink for greenhouse gases. Optimal control analysis of the model shows that a feasible steady state is possible for which the...

An oligopoly model is presented that allows the determination of feedback Nash equilibrium advertising strategies for an oligopoly. Analyses of symmetric and asymmetric oligopolies with the model show that unit contribution and advertising effectiveness have positive effects on a competitor's...

We assess which brand asset metrics provide incremental information content to accounting performance measures in explaining stock return. Our analysis focuses on the five quot;pillars,quot; i.e., central brand attributes, that form the basis for the newly updated Young and Rubicam Brand Asset...

Some past research has provided results suggesting that the financial markets mis-price customer satisfaction, i.e., firms advantaged in customer satisfaction are posited to earn positive future-period abnormal stock returns. By allowing for differences across sectors in the economy, we provide...

We find evidence that some firms attempt to inflate current-term earnings (and thereby stock price) at the time of a seasoned equity offering (SEO). Earnings inflation takes place both through accruals and real activity earnings management. The financial markets do not properly value firms...
