近年来,我国零售商供应商矛盾突出,引起了各方关注。商务部等五部委发布的《零售商供应商公平交易管理办法》,是近年来专门调整零供关系的政府部门规章,在稳定流通秩序方面发挥了一定的作用,但对此也有一些不同观点。为完善零供(买卖)关系的法律规范体系,推进和谐商业环境及商事法治建设,本文对调整零供关系的法律属性,少数零售企业恶意占压、骗取供应商贷款的综合治理,风险预誓机制等相关问题提出了自己的一些见解。 相似文献

Bayesian MCMC Mapping of Quantitative Trait Loci in a Half-sib Design: a Graphical Model Perspective
N.A. Sheehan B. Gulbrandtsen M.S. Lund D.A. Sorensen 《Revue internationale de statistique》2002,70(2):241-267
Graphical models provide a powerful and flexible approach to the analysis of complex problems in genetics. While task-specific software may be extremely efficient for any particular analysis, it is often difficult to adapt to new computational challenges. By viewing these genetic applications in a more general framework, many problems can be handled by essentially the same software. This is advantageous in an area where fast methodological development is essential. Once a method has been fully developed and tested, problem-specific software may then be required. The aim of this paper is to illustrate the potential use of a graphical model approach to genetic analyses by taking a very simple and well-understood problem by way of example. 相似文献

The aim of this paper is to provide a connection between concentration and inequality. In particular, we show that the general
entropy inequality indices are, among inequality measures, those consistent with the whole set of Hannah-Kay concentration
indices. We isolate the inequality component underlying concentration measures, obtaining an explicit additive decomposition
of the change in concentration into the change in its two components, i.e., inequality and the number of firms. This relationship
proves to be valid for the whole set of Hannah-Kay concentration indices, and embodies as particular cases some others previously
found in the literature.
We are particularly grateful to Emilio Cerdá for helpful comments on the mathematical formulation of the paper. The second

We investigate the investment decisions of Italian state-owned enterprises (SOEs) across budget constraint regimes and carry out a natural experiment that exploits a regime switch in 1987. Drawing on the theory of capital market imperfections, we apply an empirical framework for investment analysis to a panel of manufacturing SOEs in competitive industries. We identify parallels between SOEs and widely held, quoted companies afflicted by agency problems, managerial discretion, and overinvestment. We argue that, in the case of SOEs, the soft budget regime increases managerial discretion, facilitates collusion with vote-seeking politicians, and results in wasteful investment. Consistent with our predictions, we find that the regime switch disciplines SOE's investment behavior. Following a hardening of the budget constraint, managers lose discretion to indulge in collusion and overinvestment. J. Comp. Econ., June 2002 30(4), pp. 787–811.

科学技术的飞速发展、经济的全球化以及竞争的日益激烈,使得企业要想在市场上取得成功,就必须和供应商、客户建立紧密的伙伴关系,通过整体协作增强各节点企业的竞争力。对于供应链伙伴关系,可以从交易费用、资源观、博弈论等到不同视角进行研究,本文将从博弈的视角,通过企业间博弈的不同阶段,包括囚徒困境、鹿的陷阱以及单方承诺三个阶段,对供应链内企业间的伙伴关系进行探讨,揭示其内在规律。 相似文献

在全球经济一体化环境下,传统的管理模式、经营理念、业务方法已不能适应快速变化的市场运行。顾客(Customer)、竞争(Competition)和改变(Change)驱使企业发展进入新阶段。在灵活性与快速响应主宰的商业战场中,客户关系应用而生,业务流程重组和客户关系管理的结合似乎成了一种必然. 相似文献

This paper analyses the intraday lead-lag relationships between returns and volatilities in the Ibex 35 spot and futures
markets. Using hourly data, we jointly analyze the interactions between markets, estimating a bivariate error correction model
with GARCH perturbations which captures stochastically the presence of an intraday U-shaped curve for both spot and futures market volatility. Our findings show a bidirectional causal relationship between market
volatilities, with a positive feedback. This two-way transmission of volatility is consistent with market prices evolving
according to a long-run equilibrium relationship, and shocks affecting both markets in the same direction. Our empirical results
also support a unidirectional cross interaction from futures to spot market returns. This pattern suggests that the futures
market leads the spot market in order to incorporate the arrival of new information. 相似文献

This paper examines the effects of government deficits, public investment, and public capital on welfare in the transition to an aging Japan by applying a simulated general equilibrium growth model. One of the main results of this paper is that targeting only high economic growth would mislead us as to economic policies, and that a policy to reduce future government deficits is most preferable for almost all generations, even though a cut in future deficits must be followed by a decrease in public investment, thus a decrease in public capital in the future.
