We reexamine the tests for dynamic inefficiency in productive overlapping-generations economies with stochastic growth. Contrary to certain recent claims in the literature, we argue that the size of real, long-term, safe interest rates relative to average GDP growth is an inconclusive test for...

In this paper we argue that a large class of recursive contracts can be studied by means of the conventional Negishi method. A planner is responsible for prescribing current actions along with a distribution of future utility values to all agents, so as to maximize their weighted sum of...

We revisit the occurrence of self-fulfilling crises in sovereign debt markets under time-varyinginterest rates and growth. We show that, when long-term interest rates exceed growth, insolvencyis solely caused by the exhaustion of the sovereign’s debt repayment capacity subject to...

The fiscal theory of the price level asserts that the price level is determined by the ratio of outstanding public nominal debt into the present value of real primary budget surpluses of the government. We here argue that the logic of the fiscal theory fails when at least part of the public debt...

This Paper investigates the relationship between risk and productive activity and the degree of financial intermediation in a model with moral hazard. Entreprenuers can simultaneously get credit from two types of competing institutions: ‘financial intermediaries’ and ‘local lenders’. The...

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, we propose a simple geometrical method to study the occurrence of sunspot equilibria near an indeterminate steady state of a non-linear, two-dimensional economic model without any predetermined variable. We prove that, if the steady state is a saddle point of the perfect foresight...

In this paper we study the welfare effects of monetary policy in a simple overlapping generation economy in which agents voluntary contribute to a public good. Inflation has two effects at equilibrium: it increases voluntary contributions and it misallocates private consumption across time. We...

This paper investigates the relation between risk and the degree of financial intermediation in a model with moral hazard. Entrepreneurs can simultaneously get credit from two type of competing institutions:"financial intermediairies" and "local lenders". The former are competitive firms issuing...
