A probabilistic solution to high-dimensional continuous-time macro and finance models
Ji, Huang - 2023
This paper introduces the probabilistic formulation of continuous-time economic models: forward stochastic differential equations (SDE) govern the dynamics of backward-looking variables, and backward SDEs capture that of forward-looking variables. Deep learning streamlines the search for the...

The short-term effects of generative artificial intelligence on employment : evidence from an online labor market
Hui, Xiang; Reshef, Oren; Zhou, Luofeng - 2023
Generative Artificial Intelligence (AI) holds the potential to either complement knowledge workers by increasing their productivity or substitute them entirely. We examine the short-term effects of the recent release of the large language model (LLM), ChatGPT, on the employment outcomes of...

Speaking in numbers : the effect of reading performance on math performance among immigrants
Isphording, Ingo Eduard; Piopiunik, Marc; … - 2015
This paper is the first to estimate a causal effect of immigrant students' reading performance on their math performance. To overcome endogeneity issues due to unobserved ability, we apply an IV approach exploiting variation in age-at-arrival and the linguistic distance between origin and...

Oil project selection by metrics
Emhjellen, Magne; Osmundsen, Petter - 2016
The recent fall in oil prices has led to extensive capital rationing, and thereby given rise to a renewed focus on parameters for project selection which supplement net present value. While the financial crisis was creating capital constraints, the oil industry seemed to be paying great...
