We review the available evidence in three distinct domains: compliance costs, stock price reactions, and firms' decisions to exit regulated securities markets.

To control for other factors affecting exit decisions, we examine the post-SOX change in the propensity of public American targets to be bought by private acquirers rather than public ones with the corresponding change for foreign targets, which were outside the purview of SOX. Our findings are consistent with the hypothesis that SOX induced small firms to exit the public capital market during the year following its enactment. In contrast, large firms do not appear to have been affected.

The cost of health insurance has been the primary concern of small business owners for several decades. This paper examines the effect to date of two types of policy initiatives that could have substantial benefits for small business: state health insurance mandates and key components of CDHPs-HSAs, HRAs and high deductible health plans. It summarizes the key policy issues, reviews existing research evidence on the effect of these initiatives on small business and offer some conclusions for policymakers.

Externalities appear to be substantial in traffic-dense states: in California, for example, we find that the increase in traffic density from a typical additional driver increases total statewide insurance costs of other drivers by $1,725-$3,239 per year, depending on the model. High-traffic density states have large economically and statistically significant externalities in all specifications we check. In contrast, the accident externality per driver in low-traffic states appears quite small. On balance, accident externalities are so large that a correcting Pigouvian tax could raise $66 billion annually in California alone, more than all existing California state taxes during our study period, and over $220 billion per year nationally.

We find that pharmacy benefit caps are associated with higher rates of medication discontinuation across the most common therapeutic classes and that only a minority of those who discontinue use reinitiate therapy once coverage resumes. Plan members who reach their cap are more likely than others to switch plans and increase their rate of generic use; however, in most cases, the shift is temporary. Given the similarities between these plans and Part D, we make some inferences about reforms for Medicare. Geoffrey F. Joyce Health Economics http://works.bepress.com/pinar_karaca_mandic/14 http://works.bepress.com/pinar_karaca_mandic/14 Thu, 06 Sep 2007 15:07:48 PDT This paper estimates complementarities between DVD player adoption and availability of content on DVD. Model is estimated using household level panel data on adoption decisions, and panel data on the availability of movies for rental on DVD at different local regions as well as time series data on the number of movies released on DVD nationally. Estimated complementarities are statistically and economically significant, and suggest that DVD player manufacturers could achieve profit gains from subsidizing DVD content providers to release more movies on DVD.
