Pareto allocations and Competitive equilibrium
Consider the one-consumer one-firm economy.
The consumer has preferences over leisure $l\in(0,L)$ and consumption good $x ≥ 0$ represented by utility function $u(x, l) = ax + l$, where $a > 0$ is a ...

Identify the Pareto welfare weights
I am asked to identify the Pareto welfare weights from the FOC of the following problem
$max_{{x_1}{x_2}} U_1(x_1)\ st\ u_2=U_2(x_2)\ and\ x_{1n}+x_{2n}=yn$
The Langrangian is: $L=U_1(x_1)+\lambda_1(...

Pareto Set with strictly convex preferences
Suppose the agents A and B have the following utility functions $x_A y_A+12x_A+3y_A $ and $x_By_B +8x_B+9y_B$ respectively with endowments (8,30) and (10,10).
The contract curve's equation turns out ...
