We analyze optimal policy design when firms' research activity may lead to socially harmful innovations. Public intervention, affecting the expected profitability of innovation, may both thwart the incentives to undertake research (average deterrence) and guide the use to which innovation is put...

We analyze the effect of judicial errors on the innovative activity of firms. If successful, the innovative effort allows to take new actions that may be ex-post welfare enhancing (legal) or decreasing (illegal). Deterrence in this setting works by affecting the incentives to invest in...

We model an enforcement problem where firms can take a known and lawful action or seek a profitable innovation that may enhance or reduce welfare. The legislator sets fines calibrated to the harmfulness of unlawful actions. The range of fines defines norm flexibility. Expected sanctions guide...

Consider a Cournot oligopoly where producers launch new products. At first potential buyers are unaware of the product, and firms decide on levels of production, advertising expenditure and a cost-reducing investment. We find the conditions for complementarities among scale, advertising and...

Activist organizations, interest groups, unions and media reveal information about labour standards. In a world where some consumers are not self-interested, the price of a product made by a multinational enterprise and the latter's location and production decisions depend on the difference in...

For standard irreversibility theory the prospect of acquiring better information in the future should induce more flexible decisions: the “irreversibility effect”. This result relies on the definition of an irreversible position as one that would be technically or economically impossible to...

Stricter laws require more incisive and costlier enforcement. Since enforcement activity depends both on available tax revenue and the honesty of officials, the optimal legal standard of a benevolent government is increasing in per-capita income and decreasing in officials' corruption. In...
