Across developing countries, capital market inefficiencies tend to decrease and external borrowing tends to sharply increase as national wealth rises. We construct a simple model of intertemporal trade under asymmetric information which provides a coherent explanation of both these phenomenon, without appealing to imperfect capital mobility. The model can be applied to a number of policy issues in LDC lending, including the debt overhang problem, and the impact of government guarantees of private debt to foreign creditors. In the two-country general equilibrium version of the model, an increase in wealth in the rich country can induce a decline in investment in the poor country via a "siphoning effect". Finally, we present some new empirical evidence regarding the link between LDC borrowing and per capita income.
A simple stochastic model of the firm is constructed in which a dynamic monopolist who maximizes a discounted profits stream subject to labor adjustment costs and given factor prices sets output price as a distributed lag of past wages and input prices. If the observed relation of wages and prices in manufacturing arises solely from this behavior then wages and input prices are exogenous with respect to output prices. In tests using quarterly and monthly series for the straight time wage, an index of raw materials prices and the wholesale price index for manufacturing and its durable and nondurable subsectors this hypothesis cannot be refuted for the period 1955:1 to 1971:11. During the period 1926:1 to 1940:11, however, symmetrically opposite behavior is observed manufacturing wholesale prices are exogenous with respect to the wage rate, a relation which can arise if dynamically monopsonistic firms compete in product markets. Neither structural relation has withstood direct wage and price controls.
This paper examines the effect of different education financing systems on the level and distribution of resources devoted to public education. We focus on California, which in the 1970's was transformed from a system of mixed local and state financing to one of effectively pure state finance and subsequently saw its funding of public education fall between ten and fifteen percent relative to the rest of the US. We show that a simple political economy model of public finance can account for the bulk of this drop. We find that while the distribution of spending became more equal, this was mainly at the cost of a large reduction in spending in the wealthier communities with little increase for the poorer districts. Our model implies that there is no simple trade-off between equity and resources; we show that if California had moved to the opposite extreme and abolished state aid altogether, funding for public education would also have dropped by almost ten percent.
We extend the analysis of Kiyotaki and Wright, who study an economy in which the different commodities that serve as media of exchange are determined endogenously. Kiyotaki and Wright consider only symmetric, steady-state, pure-strategy equilibria, and find that for some parameter values no such equilibria exist. We consider mixed-strategy equilibria and dynamic equilibria. We prove that a steady-state equilibrium exists for all parameter values and that the number of steady-state equilibria is generically finite. We also show, however, that there may be a continuum of dynamic equilibria. Further, some dynamic equilibria display cycles.
Our goal is to provide a theoretical framework in which both positive and normative aspects of international currency can be addressed in a systematic way. To this end, we use the framework of random matching games and develop a two country model of the world economy, in which two national fiat currencies compete and may be circulated as media of exchange. There are multiple equilibria, which differ in the areas of circulation of the two currencies. In one equilibrium, the two national currencies are circulated only locally. In another, one of the national currencies is circulated as an international currency. There is also an equilibrium in which both currencies are accepted internationally. We also find an equilibrium in which the two currencies are directly exchanged. The existence conditions of these equilibria are characterized, using the relative country size and the degree of economic integration as the key parameters. In order to generate sharper predictions in the presence of multiple equilibria, we discuss an evolutionary approach to equilibrium selection, which is used to explain the evolution of the international currency as the two economies become more integrated. Some welfare implications are also discussed. For example, a country can improve its national welfare by letting its own currency circulated internationally, provided the domestic circulation is controlled for. When the total supply is fixed, however, a resulting currency shortage may reduce the national welfare.
