@DukeEcon, @DanielYiXu, @drewkoke, @lcastillomart.

Last but not least, David is a pleasure to work with. I very highly recommend him!.

8/ David also has a killer paper trying to understand the key drivers of the evolution of global imbalances in the past few decades.

7/ Overall, David's work highlights how imperfect mobility shapes climate policy outcomes and challenges simplistic predictions. Careful modeling of factor mobility frictions is essential to understand the true impacts of emissions policy.

6/ Increased factor mobility changes these dynamics: a subsidy reallocates more to the green sector and shrinks brown sector employment. Still, scale effects drive emissions up, but less dramatically. Mobility matters for policy timing & impact assessment.

5/ In the baseline model, the substitution effect is outweighed by the scale effect, driving emissions up in both green & brown sectors. The subsidy backfires, raising short- & long-term emissions.

4/ A key finding: green subsidies, meant to boost renewables, may increase emissions due to competing effects. While subsidies shift resources to green sectors (substitution effect), they lower energy prices, spurring economic output (scale effect).

3/ His model features: (a) Energy from fossil (brown) & green sources; (b) Sectoral differences in energy/input use; (c) Global trade and climate policy leakage; (d) Labor/capital adjust slowly to changes in the economy.

2/ Traditional models assume perfect mobility of resources, but David���s study shows real-world barriers can cause climate policies to underdeliver in the short & medium term, with long-term resource reallocation sometimes incomplete.

1/ David’s job market paper examines how climate policies work when labor & capital move slowly across sectors. Quick (and complete) reallocation isn't always possible, which affects how carbon taxes or green subsidies reduce emissions.

I have an outstanding student on the market! David Shin @david_d_shin studies International Trade, Macro & Environmental Econ. Here is a thread on his job market paper "Climate Policies under Dynamic Factor Adjustment".
