Testing the significance of a product of two coefficients (Or, equivalently, Ho: beta1 = 0 or beta2 = 0). This is an interesting question in the meditation analysis literature. See this for a review of conventional tests and why they won't work. See this for a new approach. The nlcom command in Stata.
Interaction terms for logit/probit models. Be careful.; testing one-sided multiple hypothesis? Use an LR test.

Most exciting developments in statistics in the last 50 years?
Sampling-based versus design-based uncertainty in regression analysis (Abadie et al., 2020, Econometrica): discusses how to calculate the standard error (sampling uncertainty) under the design-based uncertainty (randomness comes from the assignment of the treatment, instead of random sampling). This is useful for applications where a population of interest is observed in its entirety. Another approach to using the "super-population" argument for when we observe the entire population but report standard errors.
Inflation and Interest Rate Targets - a nice summary from the NBER
Another fundamental read from Abadie et al. 2022 (ReStud) - why do we use clustered standard error?
Taking logs when the dependent variable has many zero values. (NBER working paper)
