The enlargement of the general-equilibrium structure to allow default subject to penalties results in a construction of a simple mechanism for selecting a unique competitive equilibrium. We consider economies for which a common credit money can be applied to uniquely select any competitive...

The paper argues that, from a dynamic efficiency perspective, intersections of factor price frontiers are irrelevant to the choice of techniques. Because every change in technique involves a temporary loss or gain in both profit and per capita consumption within the transition period, its...

The effect of incomplete information on the term structure of interest rates is examined in the framework of a pure exchange economy under uncertainty. When the growth rate of the aggregate endowment is known, the term structure is flat and deterministic. When agents do not observe the...

In the present paper we show how simple monetary policies can mitigate real effects of credit frictions. We consider stationary overlapping generations economies in which consumers are not equally efficient in producing capital and cannot commit to repay loans. The presence of money in itself...

The paper seeks to lay out a stock-flow-based theoretical framework that provides a foundation for a general theory of pricing. Contemporary marginalist economics is usually based on the assumption that prices are set in line with the value placed on goods by consumers. It does not take into...

This essay derives the monetary character of trade, the existence of a common medium of exchange, as an outcome of the economic general equilibrium in a class of examples. The setting is a (non-monetary) Arrow-Debreu Walrasian model with the addition of two constructs: multiple budget...

Inefficient Markov-perfect equilibria (MPE) are prevalent in dynamic matching and bargaining games (DMBG). I observe this inefficiency is caused by a substantial friction commonly assumed in the literature: players must exit the market after trading once. In response, this paper studies a simple...

Gale and Sabourian (2006) discuss the existence of inefficient Markov-perfect equilibrium (MPE) in a heterogeneous market. This paper shows that the example they provide cannot be supportedas a MPE. Indeed, with two buyers and two sellers, the dispersion of bargaining positions is not...

The paper outlines a static equilibrium model, which analyses the economic development in a two-country case by considering interregional migration in R&D-sectors. The effects of migration and firm decisions on both industrial agglomeration and economic development will be shown: lock-in-effects...

In this paper, we analyze how to utilize discount rates in intergenerational projects. Firstly, neoclassical decision-making is depicted in Ramsey and overlapping-generations models (OLG-models). Afterwards we investigate the utilization of time preference rates and opportunity cost rates in an...
