This article introduces a new spatial price analysis methodology based on maximum likelihood estimation of a mixture distribution model incorporating price, transfer cost, and trade flow data. This method permits differentiation between market integration and competitive market equilibrium and derivation of intuitive measures of intermarket tradability, competitive market equilibrium, perfect integration, segmented equilibrium, and segmented disequilibrium. One can also use these estimates to derive semiparametric measures of time-varying regime probabilities to track changing market conditions. An application to trade in soybean meal among Pacific Rim economies demonstrates the usefulness of the method.  相似文献

Using credit reporting firm records on 7 million individuals in the United States, we first demonstrate that debt in collections varies significantly across the country; specifically, the South and West regions have higher shares of individuals with debt in collections than other regions. Second, we identify local factors that are strongly related to debt in collections. Results from our regression models show that neighborhoods with higher rates of debt in collections are more likely to have (1) lower health insurance coverage; (2) lower home values and homeownership rates, (3) a higher share of delinquent and underwater mortgages, (4) lower household incomes, and (5) a higher share of African Americans and Latinos. While our analysis does not identify the causal mechanisms that determine financial distress, the analyses developed here can facilitate research on such mechanisms.  相似文献

This paper investigates the changes in credit spread volatility during 1993–2001. We find that the credit spreads between junk-grade corporate bonds and Treasury bonds were significantly more volatile in the second half of this period when credit-related securities became popular. In contrast, investment-grade bonds exhibited no significant change in volatility. The junk bonds variance ratios changed from being less than one to greater than one. Using the GJR-Garch model, the conditional volatilities of junk bonds increased in the second half of the period and the mean reversion speeds slowed, suggesting a longer time for mean reversion to occur. Our analysis rules out treasury volatility, credit spread level, equity market return, T-bill rate, curvature of the Treasury curve, financial crisis, quantity of defaults and standard deviation of defaults as explanations for the increase in junk bond volatility. In contrast, volatility of equity returns provides a partial explanation of junk bond spread volatility in the later period.  相似文献

This paper uses a model of optimal household residential decisions to construct a comprehensive “true” spatial cost of living index with readily available Brazilian census data. We find evidence of a decreasing or U-shaped relationship (differing with education level and region) between the cost of living and urbanization, suggesting that both market disintegration and congestion play roles in raising costs. Controlling for spatial differences in the cost of living is shown to have important consequences for the determinants of poverty and (contrary to many previous results) to increase income inequality.  相似文献

Does World Bank lending promote deregulation with stronger incentives and critical resources or slow the process by blunting the impact of crises and indirectly promoting state control? This paper analyzes empirical links between aid flows and regulatory burden. Econometric estimates based on panel data for 83 aid receiving countries over 5 year periods from 1970 to 2000 find that World Bank lending, while not specifically targeting high or low regulatory states, is linked to lower subsequent regulation. This link holds for multilateral donors more broadly while bilateral donor funds apparently fail to influence the level of regulation.  相似文献

Unlike companies that produce tangible goods, service firms typically cannot rely on product advantage as a means for ensuring the success of a new service. Developing a competitive response to a tangible product may require significant investments of time and effort. In many cases, however, competitors can easily duplicate the core elements of a firm's new service. This fundamental difference between new products and new services means that managers who hope to find the keys to new-service success must look to factors other than sustainable product advantage. Chris Storey and Christopher Easingwood suggest that managers must understand the totality of the service offering from the customer's perspective. They explain that the purchase of a service is influenced not only by the service itself, but also by such factors as the service firm's reputation and the quality of the customer's interaction with the firm's systems and staff—in other words, by the augmented service offering (ASO). Using the results of a study they conducted in the consumer financial services industry in the U.K., they identify the components of the ASO, and they examine the relative contributions of these components to the success of new services. In their model, the ASO comprises three elements: the service product, service augmentation, and marketing support. The core of the ASO—the service product—includes such dimensions as product quality, product distinctiveness, and perceived risk. The study's results suggest that improvements in the service product open up new opportunities for the firm, but have only modest effects on sales and profitability. Rounding out the ASO model are service augmentation and marketing support. Service augmentation encompasses such dimensions as distribution strength, staff-customer interactions, and reputation. The customer recognizes and responds to these elements of the ASO, but they are not part of the product core. Marketing support involves those marketing and management actions that affect the quality of the product and its augmentation, even though customers typically are not aware of them. These elements include knowledge of the marketplace, training of contact staff, and internal marketing. Enhanced service augmentation has significant effects on profitability and sales for the firms in this study, but it does not offer enhanced opportunities. The marketing support elements contribute significantly to all aspects of performance for the firms in this study.  相似文献

Unlike in the case of delays of 10‐K or 10‐Q filings, the SEC does not require managers to disclose delays of earnings announcements to the public. Thus, for companies that are unable to report earnings by their expected date, managers face a decision: remain silent or announce the delay. Prior research has investigated all earnings delays, whether or not they are accompanied by announcements of the delay announcement, and found that the market reaction is slightly negative, on average, for companies that allow their expected earnings dates to pass without disclosing results. It's not clear, however, whether this negative reaction was due to the absence of news or to the information contained in the announcements of the earnings delays. The authors' recent study documents that earnings delay announcements are associated with an average one‐day abnormal stock return of a negative 6%. This statistically as well as economically significant reduction in value is consistent with anecdotal evidence in the popular business press as well as predictions of disclosure theories, in particular the explanation that concerns about legal liability and managerial reputation motivate managers to disclose bad news. The study also shows that almost all managers who announce earnings delays attempt to influence the market reaction by disclosing the underlying cause. Finally, the study shows that the market reaction to earnings delay announcements is positively related to future earnings changes, consistent with the role of these disclosures in providing a signal of deteriorating financial performance.  相似文献
