In structural vector autoregressive (SVAR) analysis a Markov regime switching (MS) property can be exploited to identify shocks if the reduced form error covariance matrix varies across regimes. Unfortunately, these shocks may not have a meaningful structural economic interpretation. It is discussed how statistical and conventional identifying information can be combined. The discussion is based on a VAR model for the US containing oil prices, output, consumer prices and a short-term interest rate. The system has been used for studying the causes of the early millennium economic slowdown based on traditional identification with zero and long-run restrictions and using sign restrictions. We find that previously drawn conclusions are questionable in our framework. 相似文献

Product-design perception and brand strength 总被引:1,自引:0,他引:1
In this article, we present an approach to understanding product design from a cognitive psychologist’s view. We show what
cognitive processes are involved in perceiving products. Moreover, we discuss how these processes are related to the mental
formation of brands and how they affect perceivers’ appreciation of a product’s design. 相似文献

Many developing countries are currently considering liberalisation of external capital flows. While the ultimate objective of financial opening is to raise efficiency and growth, the reform process must be carefully designed to achieve these results. A recent conference has discussed the policy choices. 相似文献

The paper examines a model of strategic infrastructure investment. Two oligopolistic firms compete on home and foreign product markets for market shares. The national governments support the firms in the market rivalry by providing cost reducing public infrastructure services that are financed out of taxing an input used in the production process. It is shown, that infrastructure policy can be used as an instrument for strategic trade policy. However, governments are facing the problem of balancing the burden of taxation and the benefits of infrastructures. The theoretical model also raises some critical issues with respect to the policy relevance of recent empirical infrastructure research. 相似文献

During the past year the Euro-currency market played a very large role in bridging over the oil-induced payments imbalances. In the interest of international monetary stability this market should now move somewhat away from the centre of the stage and leave the main responsibility for the recycling of oil funds to the official financing mechanisms. 相似文献

STRUCTURAL VECTOR AUTOREGRESSIONS: CHECKING IDENTIFYING LONG‐RUN RESTRICTIONS VIA HETEROSKEDASTICITY
Long‐run restrictions have been used extensively for identifying structural shocks in vector autoregressive (VAR) analysis. Such restrictions are typically just‐identifying but can be checked by utilizing changes in volatility. This paper reviews and contrasts the volatility models that have been used for this purpose. Three main approaches have been used, exogenously generated changes in the unconditional residual covariance matrix, changing volatility modelled by a Markov switching mechanism and multivariate generalized autoregressive conditional heteroskedasticity models. Using changes in volatility for checking long‐run identifying restrictions in structural VAR analysis is illustrated by reconsidering models for identifying fundamental components of stock prices. 相似文献
