The structural stability of different languages subject to the import of external elements is analyzed. We focus on the temporal side of the different processes interacting to produce a change in the structure of the language. That is, the rate of import and dissipation of new elements is seen...

This paper develops a machine-learning method that allows researchers to estimate heterogeneous treatment effects with panel data in a setting with many covariates. Our method, which we name the dynamic causal forest (DCF) method, extends the causal-forest method of Wager and Athey (2018) by...

This paper presents an adjusted Faustmann Rule for optimal harvest of a forest in the presence of a social cost of carbon emissions. A contribution of the paper is to do this within theoretical and numerical frameworks that take account of the dynamics and interactions of the forest's multiple...

We analyze how the threat of a potential future regime shift affects optimal management. We use a simple general growth model to analyze four cases that involve combinations of stock collapse versus changes in system dynamics, and exogenous versus endogenous probabilities of regime shift. Prior...

Motivated by tropical deforestation, we analyze (i) a novel theory of resource extraction, (ii) the optimal … conservation contract, (iii) when the donor prefers contracting with central rather than local governments, and (iv) how the donor …’s presence may induce institutional change. Deforestation can be legal or illegal in the model: each district decides how much to …

the conservation value is low, the consumption value high, and the buyer's protection cost large. The theory explains why …A conservation good (such as a tropical forest) is owned by a seller who is tempted to consume (or cut), but a buyer … benefits more from conservation. The seller does conserve if the buyer is expected to buy, but the buyer is unwilling to pay as …
