The behavior of a monopoly union in a model with optimizing agents and growing endogenous capital stock is analyzed. It is shown that the stationary state of the economy is the walrasian stationary state. Thus any unemployment is temporary. Further it is shown that unemployment may prevail...

We hypothesize that the spread of the Internet has reduced corruption, chiefly through two mechanisms. First, the Internet facilitates the dissemination of information about corrupt behavior, which raises the detection risks to shady bureaucrats and politicians. Second, the Internet has reduced...

Fifty years ago Arrow introduced contingent commodities and Debreu observed that this reinterpretation of a commodity was enough to apply the existing general equilibrium theory to uncertainty and time. This interpretation of general equilibrium theory is the Arrow-Debreu model. The complete...

This paper defines a general eqilibrium model with exchange and club formation. Agents trade multiple private goods widely in the market, can belong to several clubs, and care about the characteristics of the other members of their clubs. The space of agents is a continuum, but clubs are finite....

The paper examines the most recent data on the external debts of developing countries in order to assess whether the external debt crisis is a thing of the past, or whether there is still cause for attention and concern. The main conclusion of the paper is that while a number of middle-income...

The cointegrated VAR model is proposed as an empirically coherent framework for analyzing macroeconomic phenomena within a dynamic system of pulling and pushing forces. As an illustration we show how an economic theory for inflation and money demand gives rise to a number of hypotheses...

A premise of general equilibrium theory is that private goods are rival. Nevertheless, many private goods are shared, e.g., through barter, through co-ownership, or simply because one person’s consumption affects another person’s wellbeing. We analyze consumption externalities from the...

The increasing serial cost sharing rule of Moulin and Shenker [Econometrica 60 (1992) 1009] and the decreasing serial rule of de Frutos [Journal of Economic Theory 79 (1998) 245] have attracted attention due to their intuitive appeal and striking incentive properties. An axiomatic...

Models of preferences between outcomes over continuous time are important for individual, corporate, and social decision making, e.g., medical treatment, infrastructure development, and environmental regulation. This paper presents a foundation for such models. It shows that conditions on...

The main contribution of this paper is the construction of a metric based on optimal filtering for measuring the distortionary effect of filters. The Hodrick-Prescott filter (HP-filter) has been critizised for inducing spurious cycles when filtering macroeconomic time series with the "typical...
