How to share money creation among the members of the European Monetary Union? To address this issue, we construct a two‐country New Open‐economy Macroeconomics model of an asymmetric monetary union with an incomplete financial market and home bias in consumption. We consider two sharing rules consistent with the current regulations of the European System of Central Banks. First, each participating National Central Bank supplies half of the European Central Bank determined money creation in the monetary union. Secondly, each National Central Bank adapts the national increase in money demand, under the constraint that the total money creation in the union does not exceed the level determined by the ECB for the whole union. We show that the current sharing rule, which ignores countries’ heterogeneity, is superior in terms of welfare. The key role of the current account is emphasized. It proves an efficient decentralized mechanism for allocation of money.  相似文献

We give a condition under which the componentwise stochastic integration with respect to a given R d -valued continuous local martingale coincides with the more general vector stochastic integration defined by Jacod (1979). We then provide a result on the equivalence between the vector and the component completeness of a financial market in a special case.  相似文献

We study in this article the problem of model risk in VaR computations and document a procedure for correcting the bias due to specification and estimation errors. This practical method consists of “learning from model mistakes”, since it dynamically relies on an adjustment of the VaR estimates – based on a back‐testing framework – such as the frequency of past VaR exceptions always matches the expected probability. We finally show that integrating the model risk into the VaR computations implies a substantial minimum correction to the order of 10–40% of VaR levels.  相似文献

This study develops and tests a comprehensive framework that explains what, when, and how CEO characteristics influence firms’ innovation outcomes in R&D-intensive industries. Empirical evidence from 109 CEOs from 87 U.S.-based pharmaceutical firms over the period 2001–2013 reveals that research-oriented CEOs – those with ability and motivation for science and technology – increase their firms’ innovation outcomes. The results indicate that the CEO–innovation relationship strongly depends on the extent of CEOs’ managerial discretion, which is shaped by the organizational context. We contribute to a more comprehensive understanding of the role of CEOs in firms´ innovation performance differentials.  相似文献

The Weibull distribution plays a central role in modeling duration data. Its maximum likelihood estimator is very sensitive to outliers. We propose three robust and explicit Weibull parameter estimators: the quantile least squares, the repeated median and the median/Q n estimator. We derive their breakdown point, influence function, asymptotic variance and study their finite sample properties in a Monte Carlo study. The methods are illustrated on real lifetime data affected by a recording error.  相似文献

We introduce a new methodology to target direct transfers against poverty. Our method is based on estimation methods that focus on the poor. Using data from Tunisia, we estimate ‘focused’ transfer schemes that highly improve anti‐poverty targeting performances. Post‐transfer poverty can be substantially reduced with the new estimation method. For example, a one‐third reduction in poverty severity from proxy‐means test transfer schemes based on OLS method to focused transfer schemes requires only a few hours of computer work based on methods available on popular statistical packages. Finally, the obtained levels of undercoverage of the poor are particularly low.  相似文献

This paper presents a single machine problem which occurs in shampoo production at medium-term planning phase. The considered production plant is linked to subsidiary companies which are themselves linked to final customers. The aim is to answer subsidiary companies requests by keeping their stocks in a window defined by their safety stock and maximum inventory levels. After an introduction, we present a formal definition of the problem. Next, we present a two-phase heuristic algorithm: the first phase is based on a greedy algorithm and the second phase on the Goldberg and Tarjan algorithm for the minimum cost flow problem. Experimental testings close to industrial instances show that the heuristic performs very efficiently.  相似文献

Past research indicates that the effect of TMT functional diversity on firm performance is equivocal. We address this issue by focusing on the integrative role of the CEO, postulating that the CEO's expertise and background characteristics affect the TMT functional diversity–firm performance relationship, because of their impact on the exchange and integration of distributed knowledge within the TMT. Using a dataset of 33 Dutch and Belgian Information Technology firms we investigate the moderating role of three sets of CEO characteristics (functional background, status as founder, and shared experience with the other TMT members) on the relationship between TMT functional diversity and firm performance. Our results reveal that CEO and TMT characteristics do interact in realizing the potential advantages of distributed TMT functional expertise.  相似文献

The sustainability of cooperatives versus corporations is hotly contested. We propose that strategic choices at entry can help to explain the endurance of these two governance modes. We hypothesize that cooperatives have a survival advantage if their major drawback – high coordination costs – is curbed by high levels of member engagement at founding. Our analysis of survival rates in the US bio‐ethanol industry shows that cooperatives outlive corporations (1) if investment size at founding is large (strong financial engagement), (2) if they enter de novo instead of de alio (strong product‐market engagement) and (3) if the cooperative venture has been carefully planned from the start (greenfield entry) instead of built upon the acquisition of an existing plant (strong venture‐building engagement). These findings caution against the view that a particular mode of governance is superior or inferior to another in all circumstances.  相似文献

We find that the long‐term equity premium is consistent with both GDP growth and portfolio insurance. We use a supply‐side growth model and demonstrate that the arithmetic average stock market return and the returns on corporate assets and debt depend on GDP per capita growth. The implied equity premium matches the U.S. historical average over 1926–2001. Separately, we find that the equity premium tracks the value of a put option on the S&P 500. Our theory predicts a smaller equity premium in the future, assuming that the recent regime shifts in dividend policies, interest rates, and tax rates are permanent.  相似文献
