Costs of atrial fibrillation in five European countries: results from the Euro Heart Survey on atrial fibrillation

Abstract: Aims To estimate costs of admission and costs incurred on an annual basis by patients with atrial fibrillation (AF) in Greece, Italy, Poland, Spain, and the Netherlands. Methods and results The Euro Heart Survey on AF enrolled 5333 patients with AF in 35 European countries in 2003 and 2004. This was a bottom-up cost study conducted for the five largest contributors in terms of patients enrolled. Quantities of resource use during the enrolment admission and during 1-year follow-up were inferred from survey data and multiplied by national unit costs in order to estimate per patient costs associated with AF for each country. Mean costs of inpatient admission of an AF patient were estimated at €1363, €5252, €2322, €6360, and €6445 and mean costs incurred on an annual basis at €1507, €3225, €1010, €2315, and €2328 in Greece, Italy, Poland, Spain, and the Netherlands, respectively. Inpatient care and interventional procedures were identified as the main drivers of costs, accounting for more than 70% of total annual costs in all five countries. Conclusion Estimates of the economic burden posed by AF are critical in light of the increasing importance of AF as a public health problem.

Which Investors Fear Expropriation? Evidence from Investors' Portfolio Choices

Abstract: Using a data set that provides unprecedented detail on investors' stockholdings, we analyze whether investors take the quality of corporate governance into account when selecting stocks. We find that all categories of investors who generally enjoy only security benefits (domestic and foreign, institutional and small individual investors) are reluctant to invest in companies with weak corporate governance. In contrast, individuals who are well connected with the local financial community because they are board members or hold large blocks of at least some listed companies behave differently. They seem not to care about the expected extraction of private benefits and even prefer to invest in companies where there is more scope for it. These findings shed new light on the determinants of investor behavior and portfolio choice, and suggest that it is important to distinguish between investors who enjoy private benefits or access private information and investors who enjoy only security benefits.

Labor Laws and Innovation

Abstract: When contracts are incomplete, dismissal laws prevent employers from arbitrarily discharging employees and thereby limit employers’ ability to hold up innovating employees after an innovation is successful. Therefore, dismissal laws can enhance employees’ innovative efforts and encourage firms to invest in risky but potentially groundbreaking projects. Other forms of labor laws that do not affect dismissal of employees do not have this bright side. We find support for these predictions in empirical tests that exploit country-level changes in dismissal laws in the United States, the United Kingdom, France, and Germany: more stringent dismissal laws foster innovation, particularly in innovation-intensive industries, but other labor laws do not.
