If policy discounting is to have any welfare relevance, it must be a derivative of a social welfare function. If that derivative is to have a net present value (npv) form, the baseline allocation must be stationary. Given a stationary baseline in an overlapping generations growth economy the inter-generationally fair discount rate under the relative utilitarian welfare function equals the growt...

Emigration leads to finite changes in structure of production and sectors vanish because they cannot pay higher wages. Does emigration of one type of labour hurt the other non-emigrating type in this set up? We demonstrate various scenarios when real income of the emigrating and the non-emigrating type do not move together and in the process generalize some of the existing results in the litera...

In an exogenous-growth economy with overlapping generations we analyse local stability of a balanced growth equilibrium (bge) with respect to endowment perturbations, interpreted as transfers. We show that generically in the space of parameters equilibria around bge are locally unique and are locally differentiable functions of endowments, with derivatives given by kernels. Further, those equil...

Transactions at non-equilibrium prices are “false trades”. Under standard assumptions, markets without false trading produce Pareto-efficient outputs. This paper demonstrates graphically the complications created when false trades occur, showing that quantities produced deviate from Pareto-efficient quantities except under unique conditions. In a general equilibrium framework, this spills over ...
