We build on our earlier model of money in which bank liabilities circulate as a medium of exchange. We investigate optimal bank behavior and the resulting provision of liquidity under a range of central bank regulations. In our model, banks issue inside money under fractional reserves, facing the possibility of excess redemptions. Banks consider the float resulting from money creation and make reserve‐management decisions that affect aggregate liquidity conditions. Numerical examples demonstrate positive bank failure rates when returns to banking are low. Central bank interventions may improve banks' returns and welfare through a reduction in bank failure. 相似文献

美国政府正在对美国几家世界顶尖的金融机构采取刑事调查。高盛有罪与否?我看高盛是做了令人厌恶的事情,但它的行为并不违法。我们赞同高盛,因为高盛发展了抵押业务,并将其设计成对冲基金中最赚钱的“噱头”。其次,高盛人也清楚,投资基金可能会给投资者带来巨大的损失。其实,高盛赢在其战略,它将盈利用在了冲抵投资的失败。 相似文献

This study investigated effects of codes of ethics on perceptions of ethical behavior. Respondents from companies with codes of ethics (n = 465) rated role set members (top management, supervisors, peers, subordinates, self) as more ethical and felt more encouraged and supported for ethical behavior than respondents from companies without codes (n = 301). Key aspects of the organizational climate, such as supportiveness for ethical behavior, freedom to act ethically, and satisfaction with the outcome of ethical problems were impacted by the presence of an ethics code. The mere presence of a code of ethics appears to have a positive impact on perceptions of ethical behavior in organizations, even when respondents cannot recall specific content of the code. 相似文献

Capitalization versus Expensing: Evidence on the Uncertainty of Future Earnings from Capital Expenditures versus R&D Outlays 总被引:1,自引:0,他引:1
We propose and implement a new method to estimate the relation between R&D investments and the uncertainty of future benefits from those investments. The empirical analysis compares the relative contributions of current investments in R&D and PP&E to future earnings variability using a sample of roughly 50,000 firm-year observations from 1972–1997. Evidence is strongly consistent with the hypothesis that R&D investments generate future benefits that are far more uncertain than benefits from investments in PP&E. Our results should help the current discussion on accounting for R&D and the methodology might be helpful in standard setting in other contexts as well. 相似文献

The Effect of the Hedge Horizon on Optimal Hedge Size and Effectiveness When Prices are Cointegrated
This study compares two alternative regression specifications for sizing hedge positions and measuring hedge effectiveness: a simple regression on price changes and an error correction model (ECM). We show that, when the prices of the hedged item and the hedging instrument are cointegrated, both specifications yield similar results which depend on the hedge horizon (i.e., the time frame for measuring price changes). In particular, the estimated hedge ratio and regression R2 will both be small when price changes are measured over short intervals, but as the hedge horizon is lengthened both measures will converge toward one. These results imply that, when prices are cointegrated, a longer hedge horizon will yield an optimal hedge ratio closer to one, while at the same time enhancing the ability to qualify for hedge accounting. © 2011 Wiley Periodicals, Inc.

A research project was undertaken within a multi‐county region in southeastern Ohio to ascertain the attitudes of local residents toward future outdoor recreation development within the area. A systematic random sample of 1493 respondents was drawn from a five‐county region to test a theoretical perspective developed from selected components of social exchange theory. The findings demonstrated that the respondents held very favorable attitudes toward outdoor recreation development. Multivariate analysis of the data revealed that the theoretical model was basically supported. The findings are discussed from both applied and theoretical perspectives. 相似文献

In active investment climates where firms sequentially improve each other's products, a patent can terminate either because it expires or because a non-infringing innovation displaces its product in the market. We define the length of time until one of these happens as the effective patent life, and show how it depends on patent breadth. We distinguish lagging breadth, which protects against imitation, from leading breadth, which protects against new improved products. We compare two types of patent policy with leading breadth: (1) patents are finite but very broad, so that the effective life of a patent coincides with its statutory life, and (2) patents are long but narrow, so that the effective life of a patent ends when a better product replaces it. The former policy improves the diffusion of new products, but the latter has lower R&D costs. 相似文献

Price Dynamics in International Wheat Markets 总被引:2,自引:0,他引:2
A vector autoregression model is used to evaluate dynamic relationships among international wheat prices. The effects of freight rates and exchange rates are also considered. Forecast error variance decompositions and impulse response functions are used to investigate price dynamics in six important international wheat markets. The results suggest significant dynamic relationships among prices in different international wheat markets and between the prices and exchange rates and transportation costs.
On s'est servi d'un modéle vectoriel à autorégression pour évaluer les relations dynamiques entre les cours du blé sur le marché international. On a également tenu compte de l'inci-dence des coûts de transport et du taux de change. La décomposition prévue de la variance de l'erreur et les fonctions de réaction ponctuelle ont également permis d'approfondir la dynamique des prix sur six grands marchés internationaux du blé. Les résultats suggérent des relations dynamiques notables entre les prix sur différents marchés internationaux du blé, de meme qu'entre les prix et le taux du change et les coûts de transport. 相似文献

We analyze bureaucracy and corruption in a market with decentralized exchange and “lemons.” Exchange is modeled as a sequence of bilateral, random matches. Agents have private information about the quality of goods they produce and can supplement trade with socially inefficient bribes. Bureaucracy is modeled as a group of agents who enjoy centralized production and consumption. Transaction patterns between the bureaucracy and the private sector are fully endogenous. Centralized production and consumption in the bureaucracy give rise to low power incentives for the individual bureaucrats. As a result, private agents might bribe bureaucrats, whereas they do not bribe each other. An equilibrium with corruption and an equilibrium without corruption can coexist. We discuss some welfare implications of the model. 相似文献
