Trades and Quotes: A Bivariate Point Process 总被引:3,自引:0,他引:3
This article formulates a bivariate point process to jointlyanalyze trade and quote arrivals. In microstructure models,trades may reveal private information that is then incorporatedinto new price quotes. This article examines the speed of thisinformation flow and the circumstances that govern it. A jointlikelihood function for trade and quote arrivals is specifiedin a way that recognizes that an intervening trade sometimescensors the time between a trade and the subsequent quote. Modelsof trades and quotes are estimated for eight stocks using Tradeand Quote database (TAQ) data. The essential finding for thearrival of price quotes is that information flow variables,such as high trade arrival rates, large volume per trade, andwide bidask spreads, all predict more rapid price revisions.This means prices respond more quickly to trades when informationis flowing so that the price impacts of trades and ultimatelythe volatility of prices are high in such circumstances. 相似文献

Call and default can potentially alter the timing and amounts of promised cashflows for callable, corporate bonds. While prior research has indicated the theoretical importance of adjusting Macaulay duration for the impacts of default and call, the question of their relative impact remains a matter of debate [The High Yield Debt Market, Dow Jones Irwin, New York, 1990, p. 18; J. Finan. 53 (1998) 2225]. We develop a theoretical analysis incorporating both default and call effects on duration and test its implications employing a previously unexplored data base of Canadian, investment grade, corporate bond indices containing an unusual provision making it possible to identify callable and noncallable indices. 相似文献

Studies scrutinizing the economic aspects of student tourism at the micro-level are rare in the literature. Set against this background, the present study examines the variation in a sample of Norwegian students' length of stay at summer vacation destinations in 2014. Three estimation methods – an OLS regression model, a Weibull survival model and a zero-truncated negative binomial regression model – provide qualitatively similar results regarding how a number of determinants affect length of stay. In particular, the results show that daily trip costs, booking time, tourism and trip motives, trip month and gender explain much of the variation in length of stay. Of special interest is the comparison of two segments differing on when trip duration is determined: the “pre-fixed” returners (75% of the sample) and the “open” returners (25%). In this regard, the results suggest that the “open” returners stay longer on their trips than the “pre-fixed” ones. Finally, the study provides some implications for future length of stay research. 相似文献

This paper studies the duration of Chinese manufacturing exports and its determinants, using disaggregated 6‐digit level Harmonized System product trade data from 1995 to 2007. Cox proportional hazard, Weibull and exponential models are used to examine the effects of various factors on export duration. It is revealed that export duration tends to be rather short‐lived. It is also found that GDP and GDP per capita of the export destination have positive effects on export duration, while trade relationships with distant and landlocked countries are generally of shorter duration. In addition, export duration is longer for differentiated and parts and components products, as well as products with large initial trade values. WTO membership is also important for longer export duration. Our empirical analysis suggests that developed markets, such as the USA and the EU, are important to China, and should still be the major sources for Chinese export growth in the long run. Moreover, technical innovation of firms and free trade agreement negotiations will be helpful for sustainable export growth. 相似文献

In this paper, we combine direct arbitrage arguments and an option-pricing approach to develop a method of pricing the option for rent control. For a lump-sum payment of key money, a tenant acquires the right to rent a real estate unit for an exogenously determined controlled rent, as opposed to paying the free-market rent. The tenant may continue exercising this right as long as he or she lives. Alternatively, the tenant may sell the right to occupy the controlled rent unit and receive a fraction of the key money paid by the subsequent tenant. We value the equilibrium key money, in a representative agents partial equilibrium, while endogenously determining the expected tenure duration in a controlled rent unit. We propose a procedure for valuing rent control options different from the representative agents. Our analysis shows that under real-world levels of conditional life expectancy, the level of the fraction of the key money retained by a departing tenant has an insignificant effect on the expected tenure duration in a controlled rent unit and on the level of key money. 相似文献

A general analytical model to describe the impact of environmental disamenities on duration of sales is derived. A statistical technique to recover a sellers reservation price is proposed. An econometric procedure that consistently estimates market duration and a sellers reservation price is described. An application to the impact of highway noise on property values and market duration is presented. The estimation results show that, while highway noise has a significant negative impact on forming reservation prices and predicting sale prices, the noise effect on duration of sales is not statistically significant. Empirical evidence also shows a negative impact of market duration on reservation prices, which indicates an updating process for reservation prices over time. 相似文献

ABSTRACTGenerational cohorts can differ in their consumption patterns and preferred travel behavior. As the millennial generation represents an important economic force and influences new consumption trends, this study utilizes nationwide data and almost ideal demand system (AIDS) approach to examine expenditure patterns of Korean travelers during holidays. In this process, the joint effects of travel-related characteristics are also examined. The results of the AIDS estimation on data from 871 domestic travelers reveal significantly different travel expenditure patterns for cohorts. The findings contribute to furthering the understanding of how different generational cohorts allocate their travel budgets to respective travel expenditure categories. 相似文献
