In this paper the existence of unemployment is partly explaines as being the result of coordination failures. This is achieved by considering a standard general equilibrium modes and splitting the set of commodities in two groups. The first group contains commodities like gold. The prices of...

We analyze a Ramsey economy when net investment is constrained to be non negative. We prove existence of a competitive equilibrium when utility need not be bounded from below and the Inada-type conditions need not hold. The analysis is carried out by means of a direct and technically standard...

In this paper, we prove an existence theorem for equilibria in production economies with increasing returns, which generalizes the classic results on this topic. In particular, we eliminate both the free-disposal assumptions and any smoothness requirements on the boundary of the production sets....

In this paper, we prove an existence theorem for equilibria in production economies with increasing returns, which generalizes the classis results on this topic. In partular, we eliminate both the free-disposal assumptions and any smoothness requirements on the boundary of the production sets....

We analyse a Ramsey economy when net investment is constrained to be non negative. We prove existence of a competitive equilibrium when utility need not hold. The analysis is carried out by means of direct and technically standard strategy.

We consider a dynamic two-country, two-commodity model in which each country specializes in the production of one commodity and trades with the other to consume both goods. The amount of capital used for production in one country generates externalities in the production of the other. This is...

The fiscal theory of price determination asserts that the price level is determined by the ratio of nominal public debt to the present value of real primary surpluses. To show its fragility, we describe a cash-in-advance economy with infinitely lived real productive assets. The fiscal theory...
