Standard search models assume that consumers actively decide on the order, identity, and number of products they search. We document that online, a large fraction of searches happen in a more passive manner, with consumers merely reacting to online advertisements that do not allow them to choose the timing or the identity of products to which they will be exposed. Using a clickstream panel data set capturing full URL addresses of websites consumers visit, we show how to detect whether a click is ad-initiated.

The US Securities and Exchange Commission is considering a proposal to require some companies to disclose information relating to the risks they face from climate change. But the agency is coming under pressure to scrap or water down the proposal because of a recent Supreme Court decision.

In the face of a massive financing gap for climate-change mitigation and adaptation in developing countries, everyone accepts the need for more "creative" measures to unlock and redirect private capital. But proposals like carbon credits must be understood merely as stepping stones, rather than as lasting solutions.

How does task expertise affect the allocation of attention?

A lot of today’s widespread confusion about climate change—some of it unwitting, some of it deliberately cultivated—stems from the critical miscommunication of two little words: risk and uncertainty. To most of the public, risk means a danger that must be addressed, whereas uncertainty means a lack of clarity about whether there is any meaningful danger at all. To scientists and economists like myself, uncertainty has a starkly different meaning. It is worse than risk; it indicates the possible range of just how bad a (very real) danger will be.

A board should be at the helm of any family business, steering the business in the right direction. If you wish to have a business that is resilient and has a positive impact on all stakeholders (e.g., employees, customers, vendors, and society) you must make sure your board is intact and functioning optimally. This article offers some questions to consider as you develop best practices for your own board, such as who should be on the board, whether you need an independent director, and how often your board should meet.

We exploit regional variations in exposure to heat stress to study if physical climate risk is priced in municipal and corporate bonds as well as in equity markets. We find that local exposure to damages related to heat stress equaling 1% of GDP is associated with municipal bond yield spreads that are higher by around 15 basis points per annum (bps), the effect being larger for longer-term, revenue-only and lower-rated bonds, and arising mainly from the expected increase in energy expenditures and decrease in labor productivity.

While no legislation is perfect, the US Inflation Reduction Act of 2022 will be a game changer for the transition to clean-energy sources, both in America and around the world. By doubling down on forward-looking industrial policy, the US is suddenly poised to give Europe, China, and others a run for their money.

We revisit the firm value and pricing implications of the negative screening of sin stocks. Unlike prior work, we find that institutional ownership and valuations related to sin stocks are not different from those of other stocks after controlling for differences in fundamentals between sin and non-sin stocks. Sin stocks do not differ in the likelihood of exiting the public market, the cost of raising new equity, and in the announcement returns around negative ESG news relative to non-sin stocks, casting further doubt on whether negative screening hurts sin stocks.
