In search markets, greater spatial concentration of sellers increases price competition. At the same time, though, a greater
concentration of sellers can create a shopping externality by attracting more buyers to the site. Using housing sales data,
we test for spatial competition and shopping externality effects on prices and marketing time. We find that they reflect both
competitive and shopping externality effects from surrounding houses, although the relative strength varies with how fresh
the house is in the market, the freshness of surrounding houses, and the phase of the market cycle. New listings have the
strongest shopping externality effect on neighboring houses that have been on the market for some time. Vacant houses have
their strongest competition effects in the declining market and externality effects in the rising market. Fresh houses on
the market reap little benefit from shopping externalities in all phases of the market cycle. 相似文献

This paper investigates the influence of industry uncertainty on the decision by established firms to enter a new industry. Specifically, we examine the tension between the option to defer , which discourages entry in the presence of uncertainty, and the option to grow , which may encourage entry in the presence of uncertainty when there are early mover advantages. Empirical analysis on data from a broad array of industries revealed that the effect of uncertainty on entry is not monotonic. Our findings are the first to find support for the nonmonotonic effect of uncertainty that has only recently emerged in theoretical treatments of real options theory, and amplify the importance of considering both the option to defer and the option to grow when contemplating entry. Furthermore, we found evidence that the relationship between uncertainty and entry is moderated by: (a) irreversibility, which influences the value of the option to defer; (b) the total value of growth opportunities; and (c) early mover advantages, which magnify the value of growth options.

This study investigates the effectiveness of the Tokyo Stock Exchange (TSE)-traded Japanese 10-year JGB futures contract to hedge portfolios of Japanese bonds of differing maturity and credit quality. The bond portfolios examined are Government, AAA-, and AA-rated Eurobonds with maturities of 2, 3, 5, 7, 10, and 20 years. Consistent with the recent literature, the study employs univariate methods for calculating hedge ratios based on levels, first differences, and percentage change of each series. Out-of-sample forecasting is used to determine the effectiveness of the calculated hedge ratios for each of the bond portfolios and to determine which approach to calculating hedge ratios is the most effective. The results show that this particular futures contract does provide a good hedge, particularly for those bond terms closest to the 10-year term of the contract. There is some evidence, although not strong, that JGBs are better hedged than AAA and AA bonds. Investors should take some caution when using this futures contract to hedge bond portfolios of different maturities and credit ratings. 相似文献

This paper examines whether community banks have a niche in the production of soft information when lending to small firms. A composite measure of soft information production is created from owner ratings of bank performance characteristics using survey data from a national sample of U.S. small firms. These characteristics capture some important aspects of soft information such as the bank’s knowledge of the owner’s business. This composite measure is related to the size of the owner’s primary bank, a measure of the intensity of market competition and proxies for the strength of banking relationships. After controlling for several sources of endogeneity, this composite measure is found to be significantly higher if the owner currently banks at a CFI and experiences less loan officer turnover. 相似文献

中国的金融控股集团可界定为跨业经营,再加上金融企业资产的弱专用性,因此现有金融管理体制下存在金融控股集团发展的空间。但本文分析认为金融控股集团的经营前景不能确定,应积极、审慎地发展。 相似文献

Using a high-frequency data set of the spot Australian/US dollar, this study examines the distribution of quotes, spreads, and returns across the trading day. By identifying the direction of trade and the subsequent quote returns from contributing banks, the segmented nature of the market into market-makers and informed and uninformed traders is investigated. The results suggest that the economic gain possible from private information is maximised over 2 to 5 quotes and is rapidly eroded by 20 quotes (about 2 min later during busy trading times) as other new information enters the market. Also, the analysis is revealing of discontinuities in trading and the volatility of pricing across the trading day. 相似文献

The replicating portfolio (RP) approach to the calculation of capital for life insurance portfolios is an industry standard. The RP is obtained from projecting the terminal loss of discounted asset–liability cash flows on a set of factors generated by a family of financial instruments that can be efficiently simulated. We provide the mathematical foundations and a novel dynamic and path-dependent RP approach for real-world and risk-neutral sampling. We show that our RP approach yields asymptotically consistent capital estimators if the chaotic representation property holds. We illustrate the tractability of the RP approach by three numerical examples. 相似文献

In the framework of an incomplete financial market where the stock price dynamics are modeled by a continuous semimartingale (not necessarily Markovian), an explicit second-order expansion formula for the power investor’s value function—seen as a function of the underlying market price of risk process—is provided. This allows us to provide first-order approximations of the optimal primal and dual controls. Two specific calibrated numerical examples illustrating the accuracy of the method are also given. 相似文献

We study the formation of derivative prices in an equilibrium between risk-neutral agents with heterogeneous beliefs about the dynamics of the underlying. Under the condition that short-selling is limited, we prove the existence of a unique equilibrium price and show that it incorporates the speculative value of possibly reselling the derivative. This value typically leads to a bubble; that is, the price exceeds the autonomous valuation of any given agent. Mathematically, the equilibrium price operator is of the same nonlinear form that is obtained in single-agent settings with worst-case aversion against model uncertainty. Thus, our equilibrium leads to a novel interpretation of this price. 相似文献
