Since the passage of the Interstate Commerce Act (1897) and the Sherman Act (1890), regulation and antitrust have operated as competing mechanisms to control competition. Regulation produced cross-subsidies and favors to special interests, but specified prices and rules of mandatory dealing....

We generalize von der Fehr and Harbord's (1993) multi-unit auction model for the case of a deterministic demand allowing for any technology mix and elastic demand in order to account for demand side bidding. We obtain a general characterization of the equilibrium and show that the Cournot model...

Prices for many goods and services in Belgium are higher than in other countries, reflecting generally weak competitive pressures. The government has recently introduced several reforms to strengthen the competition policy framework. Nevertheless, to reap the full benefits of competitive...

Previous theoretical research provides opposing arguments regarding the effect of environmental regulation on profitability. This study provides empirical evidence on this debated effect by testing the "strong" version of the Porter hypothesis. We employ panel data analysis to examine the effect...

Constitution and agriculture now interrelate between two fundamental parameters: the multifunctional principle on the one hand, with the emphasis on the new relations between town and country, and, on the other hand, the multiplicity of sources, overturning the traditional legal reference...

We use cross-national harmonized micro data from a broad sample of developed and developing countries and investigate the heterogeneity of the effect of entry, contract enforcement regulation, and financial development on both the decision to become an entrepreneur and the level of employment of...

Dynamic programming is the foundation of dynamic economic analysis and often requires numerical solution methods. Standard methods are either slow or unstable. These instabilities are avoided when one uses modern methods from numerical optimization and approximation. Furthermore, large dynamic...

We use difference-in-differences research designs to estimate the effects of abortion bans on births at the county level, leveraging data on changes in driving distance and appointment availability at the nearest facility where abortion remains legal. We find that bans alone increase births, but...

In overturning Roe v. Wade and triggering laws in many states that ban or severely restrict abortions, the Supreme Court's landmark 2022 Dobbs decision dramatically altered the landscape for reproductive health in the U.S. Prior research has highlighted the far-reaching impact of abortion...

With the goal of lowering incentives for alcohol and substance abuse, U.S. states have historically permitted private health insurers to deny reimbursement of medical claims stemming from alcohol or opioid impairment. However, a potential unintended consequence of such "exclusion provisions" is...
