This article proposes a new approach to testing for the hypothesisof a single priced risk factor driving the term structure ofinterest rates. The method does not rely on any parametric specificationof the state variable dynamics or the market price of risk.It simply exploits the constraint imposed by the no-arbitragecondition on instantaneous expected bond returns. In order toachieve our goal, we develop a Kolmogorov-Smirnov test and applyit to data on Treasury bills and bonds for both the United Statesand Spain. We find that the single risk factor hypothesis cannotbe rejected for either dataset. 相似文献

Lead markets, innovation differentials and growth 总被引:1,自引:0,他引:1
Marian Beise 《International Economics and Economic Policy》2005,1(4):305-328
This article suggests that the specialization of countries in international trade is determined by the lead-lag market pattern of national markets. Many internationally successful innovations have been adopted first in one country while other countries initially either preferred other designs or an established product. A model for the international diffusion of innovations is presented in which nationally preferred innovation designs compete to become a globally dominant design. In this model, there are country-specific market attributes that increase the likelihood that the choice a country makes among alternative technologies is followed around the world. It is argued that technological knowledge gaps are not the origin of an international competitive advantage. Instead, a country gains a competitive advantage because a specific innovation design was adopted earlier than in any other country. This gives local firms a head start in producing, gathering marketing intelligence and securing the property rights of a globally successful innovation. In countries with lag market characteristics, domestic innovations are less likely to get adopted worldwide. Lag markets often switch from a domestic innovation design to a foreign innovation design, which increases imports. The lead-lag market explanation of trade specialization has implications for national policies. In this model domestic innovations do not always foster exports; idiosyncratic innovations induced by lag market contexts can hamper the export chances of local firms and in the end lead to an increase in imports. It is suggested that in order to increase exports, national policies have to distinguish between a domestic lead and lag market context in each industry. While in a lead market context, traditional policy instruments that enhance the rate of innovations are effective, in a lag market situation national follower strategies are more appropriate. 相似文献

The enterprise management informatization construction is complex system engineering. The paper begins with the information management integration idea, and adopts the method of enterprise management system integration. The integration of SCM, ERP and CRM can solve the defects of "information flooding" and "information separate island". Firstly, the paper explains the concept of integration. Secondly, it analyses the three levels of the enterprise management system integration. Thirdly, the composition of the enterprise management system integration is discussed. Finally, it puts forward the integration mode of SCM, ERP and CRM under the E-commerce environment. 相似文献

Motivated by the implied stochastic volatility literature (Britten–Jones and Neuberger, forthcoming; Derman and Kani, 1997; Ledoit and Santa–Clara, 1998) this paper proposes a new and general method for constructing smile–consistent stochastic volatility models. The method is developed by recognising that option pricing and hedging can be accomplished via the simulation of the implied risk neutral distribution. We devise an algorithm for the simulation of the implied distribution, when the first two moments change over time. The algorithm can be implemented easily, and it is based on an economic interpretation of the concept of mixture of distributions. It can also be generalised to cases where more complicated forms for the mixture are assumed. 相似文献

Determinants of Current Account Imbalances in 16 OECD Countries: An Out-Of-Sample Perspective 总被引:1,自引:0,他引:1
We employ panel data as well as country-specific models to uncover empirically the determinants of current account imbalances.
We find evidence of slope heterogeneity likely rendering the fixed-effect estimator inconsistent. Mean group estimation is
followed to overcome the latter difficulty. Both estimation techniques are evaluated by means of in- and out-of-sample criteria.
The mean group estimator outperforms the fixed-effect approach and, moreover, only three economic variables are found to impact
on the current account balance significantly. These are the government budget balance, the domestic output gap and the changes
of the terms of trade. We finally propose a parsimonious dynamic model of the current account, including only these variables
and illustrate that it has similar predictive accuracy as country-specific benchmark models.

Simple sufficient conditions for the existence of a unique equivalent martingale measure are provided. Furthermore, these
conditions give us a handle on situations where an equivalent martingale measure cannot exist. The existence of a unique equivalent
martingale measure is of relevance to problems in mathematical finance. Two examples of models for which the question of existence
was unresolved are studied. By means of our results existence of a unique equivalent measure up to an explosion time is proved. 相似文献

Our paper provides a brief review and summary of issues and advances in the use of latent structure and other finite mixture models in the analysis of choice data. Focus is directed to three primary areas: (1) estimation and computational issues, (2) specification and interpretation issues, and (3) future research issues. We comment on what latent structure models have promised, what has been, to date, delivered, and what we should look forward to in the future. 相似文献

This paper uses the binary choice model to identify the factors that are significantly influencing the household purchase decisions of seafood products for home consumption in Auckland, New Zealand. It is found that ‘quality’ and ‘cooking easiness’ are the main product attributes that significantly influence households’ choices of seafood in Auckland. Also, the representative household has shown a strong preference for fresh and other alternative seafood products, including processed, smoked and canned, over frozen products. Retail outlets are found to be more attractive to the household purchasing seafood for home consumption. The New Zealand seafood industry may find this baseline study useful as a guide to developing future research structure on the domestic market. 相似文献

This paper provides a side-by-side comparison of loan-level statistical models for fixed- and adjustable-rate mortgages. Multinomial logit models for quarterly conditional probabilities of default and prepayment are estimated. We find that the estimated impacts of embedded option values for prepayment and default are generally quite similar across both FRM and ARM loans, providing additional empirical support for the basic predictions of the options theory. We also find that differences in estimates of conditional probabilities of prepayment and default associated with mortgage age, origination period, original LTV, and relative loan size, indicate the continued significance of these other economic and demographic factors for empirical models of mortgage terminations. 相似文献
