• Abstract: Special Purpose Acquisition Companies (SPACs) experienced a skyrocket rise in 2020-2021 but rapidly collapsed in 2022, raising concerns about their long-term viability. This paper explores the structural flaws that underlie the SPAC boom-and-bust cycle. Three key issues emerge: (1) the misalignment between risk and return, which turns SPACs into speculative instruments rather than investment vehicles; (2) agency problems, where sponsors have distorted incentives with limited governance; and (3) the failure of traditional market gatekeepers – such as underwriters and M&A advisors – in certifying deal quality. Empirical evidence from updated data on redemption rates, deal performance, and the role of financial intermediaries, supports the need for regulatory and structural reforms to make SPACs a viable alternative to traditional IPOs and venture capital.

Salient Cues of Economic Transitions in Analyst Forecasting: Evidence from the Electric Vehicle Era with Jarrad Harford, Weikai Li, and Yonghao Zhai

• Abstract: We examine how salient cues of broad economic trends shape financial analysts’ forecasting, using U.S. MSA-level electric vehicle (EV) adoption as a proxy for local green salience. After controlling for MSA, analyst, and firm characteristics, analysts in high-EV areas make more accurate forecasts for green firms. This improvement reflects not a net gain in forecasting ability, but a reallocation of limited attention and effort toward green firms. The effect is stronger among male, younger, and less busy analysts, and for harder-to-value firms, and is accompanied by more frequent forecast revisions, greater climate-related engagement during earnings calls, and increased use of opportunity-oriented climate language in analysts’ reports. Markets respond more strongly to forecast revisions by these analysts, and the information environment of green firms improves under their coverage.
