This paper adds to the literature on the Sarbanes-Oxley Act's net effects by looking at whether its passage was associated with a change in innovation and patenting. Its effects are separated into temporary uncertainty and changes in long term investment incentives in a dynamic programming...

Although there are many studies of determinants of vegetarianism and veganism, there have been no previous studies of how their rates in a population jointly change over time. In this paper, we present a flexible model of vegetarian and vegan dietary choices, and derive the joint dynamics of...

In this paper, we empirically investigate the dynamics of the marginal propensity to pirate for computer software. We introduce a state space formulation that allows us to estimate error structures and parameter significance, in contrast to previous work. For data from 1987-92, we find a rising...

We present an information good pricing model with persistently heterogeneous consumers and a rising marginal propensity for them to pirate. Three offsetting pricing mechanisms occur: skimming, compressing price changes, and delaying product launch. We identify a novel trade off in piracy's...

This paper assesses how financial regulation, in the form of the Sarbanes-Oxley Act (SOX), affects industrial innovation. We describe the decision faced by an investor considering an innovative project before, at the time of, and subsequent to SOX. SOX is shown to create a real option value for...

We look at the effect of the US Sarbanes-Oxley (SOX) financial regulation on industrial innovation. Our theoretical framework shows it creating immediate uncertainty about its costs and future resolution of cost and managerial performance uncertainty. Real option value is created for investment...

We study the effect of different information sources on diffusion between and within companies. Our model of economically optimising farmers replicates results from dual process persuasion theory, and predicts that inter-firm diffusion will be primarily affected by reliable, easily accessible...
