In this paper, we consider the determinacy of equilibrium prices, interest rate and income in an economy with liquidity constraints and capital accumulation. In particular, we show that, even though no extrinsic uncertainty effects fundamentals, under some conditions, rational expectations...

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

Money provides liquidity services through a cash-in-advance constraint. The exchange of commodities and assets extends over an infinite horizon under uncertainty and complete asset market. Monetary policy sets the path of rates of interest and accommodates the demand for balances. Competitive...

Competitive equilibrium allocations are indeterminate when the net trades in commodities are constrained, while the asset market is incomplete.

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...
