in this paper, the reduced dierential transform method is investigated fora nonlinear partial dierential equation modeling nematic liquid crystals, itis called the hunter-saxton equation. the main advantage of this methodis that it can be applied directly to nonlinear dierential equations withoutrequiring linearization, discretization, or perturbation. it is a semi analytical-numerical metho...

Norms play an important role in shaping behavior, but our understanding of norm formation is incomplete. This paper views norms as shared values. In the model, players choose values, motivated by economic considerations and, crucially, also by the desire for esteem. The comparative statics are driven by the following tension: players obtain more esteem from peers if they conform; but they may o...

As economists introduce more and more cognitive biases into economic models, an important question is whether we can distinguish these biases empirically. We present a simple model of welfare program participation that nests two well-documented cognitive biases: projection bias and present bias. We argue that agents with present bias and projection bias will exhibit di¤erent attitude toward tim...
