Multinational companies face increasing risks arising from external risk factors, e.g. exchange rates, interest rates and commodity prices, which they have learned to hedge using derivatives. However, despite increasing disclosure requirements, a firm's net risk profile may not be transparent to shareholders. We develop the ‘Component Value‐at‐Risk (VaR)’ framework for companies to identify the multi‐dimensional downside risk profile as perceived by shareholders. This framework allows for decomposing downside risk into components that are attributable to each of the underlying risk factors. The firm can compare this perceived VaR, including its composition and dynamics, to an internal VaR based on net exposures as it is known to the company. Any differences may lead to surprises at times of earnings announcements and thus constitute a litigation threat to the firm. It may reduce this information asymmetry through targeted communication efforts. 相似文献

Kalyanam and Shively [1998. Estimating irregular pricing effects: a stochastic spline regression approach. Journal of Marketing Research 35 (1), 16–29] and van Heerde et al. [2001. Semiparametric analysis to estimate the deal effect curve. Journal of Marketing Research 38 (2), 197–215] have demonstrated the usefulness of nonparametric regression to estimate pricing effects flexibly. The empirical results of these two studies, however, also revealed that nonparametric regression may suffer from too much flexibility leading to nonmonotonic shapes for price effects. In this paper, we show how the problem of nonmonotonicity can be dealt with without losing the power of flexible estimation techniques. We propose a semiparametric approach based on Bayesian P-splines with monotonicity constraints imposed on own- and cross-price effects. In an empirical application, we illustrate that flexible estimation of own- and cross-price effects can improve the predictive validity of a sales response model substantially, even when price response curves were constrained to show a monotonic shape, as suggested by economic theory. We also discuss the consequences from an unconstrained estimation of price effects. 相似文献

Conclusion The corporate tax policy of the new EU member states does create pressures for some of the old member states to reduce their
corporate taxes, in particular statutory corporate tax rates. But reacting to this pressure by enforcing mimimum tax rates
in the EU would be counterproductive. It would slow down the economic catching up process in eastern Europe and question the
competitiveness of the entire EU as a location for investment compared to other countries and regions in the world economy.
There are potential benefits from more coordination in the field of corporate taxation, but this coordination should aim at
removing tax obstacles to border-crossing investment and at reducing the compliance costs of the tax system. This requires
targeted measures in the area of tax base coordination. Introducing minimum corporate tax rates, in contrast, would be harmful
for both high and low tax countries in the EU. 相似文献

Public debt in Europe has risen continuously over the last two decades. How is the transition to European Economic and Monetary Union, with the increasing economic interdependence between individual member states which it involves, likely to affect this situation? Which policy issues are of particular relevance in this setting? 相似文献
