Private money and bank runs

Hongfei Sun; Stella Huangfu

This paper studies bank runs in a model with private money. We show that allowing claims on demand deposits to circulate as a medium of exchange can help prevent bank runs. In our model, there exists a unique banking equilibrium where no one demands early withdrawals of real goods and agents in need of liquidity use private money to finance consumption. With private money, the unique equilibrium not only eliminates bank runs but also improves banking efficiency. The implications of our model are consistent with the evidence from the banking history of the United States. Ce memoire etudie les ruees sur les banques dans un modele avec monnaie privee. On montre que permettre aux droits sur des depots bancaires de circuler comme moyen d’echange pourrait aider a prevenir les ruees sur les banques. Dans le modele presente, il existe un equilibre bancaire unique ou personne ne demande de retraits prematures de biens reels, et ou les agents qui ont besoin de liquidites utilisent la monnaie privee pour financer leur consommation. Avec la monnaie privee, l’equilibre unique non seulement elimine les ruees sur les banques mais encore ameliore l’efficacite des banques. Les implications de ce modele s’arriment bien aux observations qu’on tire de l’histoire bancaire des Etats‐Unis.

Monetary and Fiscal Policies in a Heterogeneous-Agent Economy

Hongfei Sun

I study the effects of long-run inflation and income taxation in an economy where households face uninsurable idiosyncratic risks. I construct a tractable competitive search framework that generates dispersion of prices, income and wealth. I analytically characterize the stationary equilibrium and the policy effects on individual choices. Quantitative analysis finds that monetary and fiscal policies have distinctive effects on macro aggregates, such as output, savings, wealth dispersion, income and consumption inequalities. There can be a hump-shape relationship between welfare and the respective policies. Overall, welfare can be maximized by a deviation from the Friedman rule, paired with distortionary income taxation.

Monetary and fiscal policies in a heterogeneous-agent economy

Hongfei Sun; Chenggang Zhou

English Abstract: We study the effects of long�?run inflation and income taxation in an economy where households face uninsurable idiosyncratic risks. We construct a tractable competitive�?search framework that generates dispersion of prices, income and wealth. We analytically characterize the stationary equilibrium and the policy effects on individual choices. Quantitative analysis finds that monetary and fiscal policies have distinct effects on macro aggregates, such as output, savings and wealth, income and consumption inequalities. There is a hump�?shaped relationship between welfare and the respective policies. Overall, welfare is maximized by a deviation from the Friedman rule, paired with distortionary income taxation. French Abstract: Politiques fiscales et monétaires dans une économie où les agents sont hétérogènes. Les auteurs étudient les effets de l’inflation à long terme et de l’impôt sur le revenu dans une économie où les ménages font face à des risques idiosyncratiques non�?assurables. Ils construisent un cadre conceptuel concurrence�?recherche maniable qui génère la dispersion des prix, du revenu, et de la richesse. On caractérise analytiquement l’équilibre stationnaire et les effets des politiques sur les choix individuels. L’analyse quantitative révèle que les politiques monétaires et fiscales ont des effets distincts sur les agrégats macro�?économiques comme le produit et les épargnes, et sur les inégalités de richesse, des revenus et de la consommation. Il y a une relation en forme de bosse entre le bien�?être et les politiques respectives. Au total, le bien�?être est maximisé par une déviation de la règle de Friedman pairée avec la fiscalité sur le revenu discrétionnaire.
