This paper demonstrates that a pollution tax with a fixed cost component capturing an “ambient tax” may lead, by itself, to stratification between clean and dirty firms without heterogeneous preferences or increasing returns. We construct a simple model with two locations and two industries...

Pagan and Shannon's (1985) widely used approach employs local linearizations of a system of non-linear equations to obtain asymptotic distributions for the endogenous parameters (such as prices) from distributions over the exogenous parameters (such as estimates of taste, technology, or policy...

We provide an alternative proof of the existence of core allocations in exchange economies with differential information and infinite dimensional commodity spaces. We also identify a critical feature of information sharing rules that ensures nonemptiness of the core. In essence, the only...
