- Behavioral and organizational research
Profile
Quantitative work grounded in economic research
My work connects applied data science with formal research training: building models, evaluating evidence, and communicating uncertainty clearly enough to support decisions.
Applied data science
Machine learning workflows with attention to confidence, error analysis, and the practical conditions under which model outputs are useful.
Research depth
Academic work on behavioral economics, incentives, social preferences, and organizational decision-making.

Efficiency Wages with Motivated Agents
Games and Economic Behavior, 145, pp. 66-83
Abstract
Many jobs serve a social purpose beyond profit maximization. This paper uses a modified principal-agent gift-exchange game with positive externality to study how workers' prosocial motivation interacts with efficiency wages in stimulating effort. The results show that prosocial motivation and efficiency wages are independent in stimulating effort, while principals offer higher wages in the prosocial treatment because they underestimate reciprocity in the standard gift-exchange environment.

Managing Anticipation and Reference-Dependent Choice
Journal of Mathematical Economics, 112, 102988
Abstract
The paper develops a model of reference-dependent choice in which the reference point may be any convex combination of possible outcomes under a consumption lottery. It introduces solution concepts, characterizes them on choice data, and identifies the model's parameters.

Optimal Contracting with Endogenous Project Mission
Journal of the European Economic Association, 18(5), pp. 2647-2676
Abstract
The paper studies how organizations can choose a project mission to attract, incentivize, and screen workers. It analyzes how contractual environments shape the optimal distance between the organization's preferred mission and the agents' preferred mission.
