On the (nonlinear) relationship between exchange rate uncertainty and trade — An investigation of US trade figures in the group of seven

In this paper bilateral models formalizing monthly growth of US imports and exports are employed to investigate the potential of nonlinear relationships linking exchange rate uncertainty and trade growth. Parametric linear and nonlinear as well as semiparametric time series models are evaluated in terms of fitting and ex ante forecasting. The overall impact of exchange rate variations on trade growth is found to be weak. In periods of large exchange rate variations, trade growth forecasts gain from conditioning on volatility. Empirical results support the view that the relationship of interest might be non-linear and, moreover, lacks homogeneity across countries and imports vs. exports. JEL no. C14, C22, F31, F41     

The dynamics of factors affecting the adoption of innovations

An abundance of IT innovations are constantly struggling for market acceptance. Various models have been proposed in the literature in order to aid understanding of the principles behind the adoption of IT innovations, but most of them implicitly assume that the factors explaining adoption decisions do not change over time. This study challenges that assumption and adds to the existing literature by investigating the dynamics of the factors influencing adoption. Our general proposition is that the driving factors in adopting innovations will change as the diffusion of the innovation in the market progresses. A large-scale empirical study was carried out among medium-sized companies in a variety of European countries and industries concerning the adoption of enterprise resource planning (ERP) software. The findings strongly indicate that the factors affecting late adoption of ERP differ significantly from the factors explaining early adoption. At early stages of the diffusion process adoption tends to be especially driven by a combination of internal strategic drives and attitudes of the firm together with external forces like industry competition and supplier activities. Later on, the mix of adoption stimulating factors seems to be focusing more on implementation issues such as the scalability of the system, the number of seats and the yearly available budget. The study leads to both new methodological insights and substantive conclusions that also have practical implications.

An algebraic theory of portfolio allocation

Summary. Using group and majorization theory, we explore what can be established about allocation of funds among assets when asymmetries in the returns vector are carefully controlled. The key insight is that preferences over allocations can be partially ordered via majorized convex hulls that have been generated by a permutation group. Group transitivity suffices to ensure complete portfolio diversification. Point-wise stabilizer subgroups admit sectoral separability in fund allocations. We also bound the admissible allocation vector by a set of linear constraints the coefficients of which are determined by group operations on location and scale asymmetries in the rate of returns vector. For a distribution that is symmetric under a reflection group, the linear constraints may be further strengthened whenever there exists an hyperplane that separates convex sets.

Financing enterprise development in sub-Saharan Africa

This paper examines some critical gaps in the financial infrastructurein sub-Saharan Africa, which have contributed to the poor performanceof productive investment by private agents. It first analysesthe performance of financial systems, encompassing both formaland informal financial sectors, in relation to the changingpolicy environment, and key features of the financial marketstructure. It then identifies those gaps in financial servicesthat have been particularly detrimental to private investment,enterprise growth and transformation. Finally, the paper considerspolicy implications drawn from East Asian experiences with respectto financial policies, institutional arrangements and marketintegration measures for financing enterprise development.     

财务动态治理论纲

传统财务治理理论侧重于财务治理结构和权利分布状态等静态范畴的研究,而忽略了财务动态治理的专门研究.财务治理可分解为基于企业公平的财务静态治理和基于企业效率的财务动态治理,它在本质上是一个二元价值体系,在实践上表现为企业公平和效率的并行与平衡.财务动态治理是对传统财务治理的继承和超越,它是剩余公司治理的集中领域和公司动态治理的核心,其理论基础溯源于企业产权契约理论、公司治理理论、公允价值会计计量理论和财务治理理论.以不完全合同中的完备部分和不完备部分为标准,财权可划分为通用财权和剩余财权.剩余财权配置是财务动态治理的核心,财务动态治理的基本内容包括动态治理结构、治理机制和治理行为规范.

基于模块化的企业价值网络及其竞争优势研究

以价值模块化为基础,传统的集合型价值链经过解构、整合和重建形成具有差异化竞争优势的模块化价值链。不同企业的价值模块和模块化价值链在共同的界面标准内交叉连接、融合贯通,形成企业价值网络。企业价值网络集聚各成员企业的优势资源,将各种能力要素协同在一个无形的网络平台上,通过不同组织模块之间的协作、创新和竞争,能够产生新的竞争优势。企业以价值模块化为基础,对自身价值链进行整合,融入企业价值网络,能够分享网络内成员企业的优势资源和技术创新成果,共享模块化经济,增强企业核心竞争力和抗风险能力。模块化时代,企业之间的竞争已经演进为企业价值网络之间的竞争。
