Models of firm microstructure are becoming now a standard building block in macroeconomics, trade, and development. This literature builds on the recognition that firm heterogeneity and the allocation of resources across firms plays a key role in determining aggregate productivity and the gains from trade. Barriers to the efficient allocation of resources across firms have been recently recognized to play a key role in economic development. This paper focuses on this methodological contribution, the link between firm microstructure and economic aggregates.  相似文献

A central proposition in research on the role of banks in the transmission mechanism is that monetary policy imparts a direct impact on deposits and that deposits act as the driving force of bank lending. This paper argues that the emphasis on policy‐induced changes in deposits is misplaced. A reformulation of the bank lending channel is proposed that works primarily through the impact of monetary policy on banks’ balance sheet strength and risk perception. Such a recasting implies, contrary to conventional wisdom, that greater reliance on market‐based funding enhances the importance of the channel.  相似文献

Inventory record inaccuracy (IRI) challenges multichannel retailers in fulfilling both brick‐and‐mortar and direct channel demands from their distribution centers. The nature and damaging effects of IRI largely go unnoticed because retailers assume daily IRI remains stable over time within the replenishment cycle. While research shows that a high level of IRI is damaging, in reality the level of IRI can change every day. We posit that daily IRI variation increases the uncertainty in the system to negatively affect inventory and service levels. Our research uses data collected daily from a multichannel retailer to ground a discrete‐event simulation experiment. Going beyond testing just the level of IRI, we evaluate daily IRI variation's impact on operating performance. What we find in our empirical data challenges extant assumptions regarding the characteristics of IRI. In addition, our simulation results reveal that daily IRI variation has a paradoxical effect: it increases inventory levels while also decreasing service levels. Moreover, we also reveal that brick‐and‐mortar and direct channels are impacted differently. Our findings show that assumptions and practices that ignore daily IRI variation need revising. For managers, we demonstrate how periods of multiday counting help assess their daily IRI variation and indicate what the causes may be.  相似文献

在无线通信系统中,基站可以根据信道互易性使用波束成形(Beam Forming)技术提升系统性能。信道互易性的准确程度对性能是有影响的,因此需要对其分析以指导系统设计。对长期演进(LTE)系统的互易性进行建模,指出了终端发送天线和接收天线数目的不对称性,以及基站信道估计的误差对信道互易性的影响。通过数值仿真验证了不理想的信道互易性使波束成形性能受到损失,并为系统改进提出思路。其结论容易推广到其他应用波束成形的无线通信系统。  相似文献

Exploiting the panel VAR GMM estimator's features, macroeconomic country factors are combined with micro-economic bank data to test for the risk taking channel in the Euro Area. According to prior expectations based on an extended DSGE model, the analysis demonstrates that the monetary policy incentives bank risk taking by increasing the bank leverage, but it is not able to influence the level of credit risk. However, deeper investigations indicates the Taylor gap adds to the bank risk appetite in all its forms, while regarding the reactions to target variables, movements in the interest rate smooth the bank risk.  相似文献

The paper considers the Russian privatization process and examines how its deviation from the competitive sale standard was likely to affect wealth inequality. (Privatization here is defined narrowly as the transfer of existing assets from government ownership to private hands.) While empirical evaluation is all but impossible due to the dearth of reliable data, it is feasible to analyze the institutional features of Russian privatization in terms of their effect on redistribution of wealth. The paper argues that the most relevant and interesting issue is to evaluate privatization's distributional consequences relative to the informal pre-reform property rights. In light of this, privatization is modelled as a rent-seeking contest with incumbency advantage of enterprise managers who initially held the greatest informal rights over assets. The rent-seeking contest is shown to strongly magnify this pre-reform wealth inequality reflected in the incumbency advantage.
In addition, the paper analyzes the distributional consequences for various wealth groups of the differences in the composition of their pre-reform informal wealth, most importantly a relatively large share of housing assets in the wealth of the poor. The effect of wealth redistribution on economic growth in Russia is also discussed.  相似文献

Abstract

Pricing issues can become complex and confusing to marketing students. Pricing issues can become even more confusing when prices at each level of the distribution channel are considered. This paper introduces a “what-if” spreadsheet approach to helping students develop a working understanding of how pricing decisions affect distribution channel strategy. Classroom experience with the approach has demonstrated its viability as a computer-assisted learning exercise for this complex topic.  相似文献

产权的作用机制在于产权制度使财产所有者有动力关心财产的使用和增值,使所有者的努力程度与财产收益正相关。对于不断发生“公共物悲剧”现象,应科学界定环境污染的初始产权,完善环境污染权的交易制度,以实现资源的优化配置。  相似文献
