Preferenced Trading,Quote Competition,and Market Quality: Evidence from Decimalization on the NYSE

We examine the impact of decimalization on preferenced trading in NYSE‐listed stocks and show a significant decline in preferenced trading around decimalization. For the largest NYSE stocks, the total decline is nearly 22%. We also find a negative correlation between the changes in preferenced trading and the changes in quote competition intensity, and a positive correlation between the changes in preferenced trading and the changes in spreads. Consistent with the cream skimming hypothesis, we find that abnormal changes in information asymmetry cost for NYSE trades are positively correlated with the changes in preferenced trading.     

Allocation problems among sharing groups

We deal with allocation problems among sharing groups. There are n agents. The agents are divided into several sharing groups. A homogeneous good is allocated among sharing groups rather than among the agents. The good is a private good for sharing groups, and a public good for the members of each sharing group. That is, all of them in the same sharing group can consume it without rivalry. We introduce some allocation rules and axioms. The utilitarian allocation rule and the egalitarian allocation rule are characterized by some axioms.     

Home-based telecommuting and commuting behavior

The existing spatial models for home-based telecommuting assume that all the jobs are located at the central business district. At the same time, they do not duly treat the conflicting interests of the employer and the employee in adopting the telecommuting as an alternative work mode. The first objective of the paper is to present a spatial equilibrium model overcoming some of these important modeling drawbacks. The second objective is substantive. In the city where telecommuting is adopted, the conventional commuting pattern may no longer prevail: one may commute more to distant workplace than to the nearby workplace. Using the concept of relocation and substitution effects, I show how these two effects are interacting in their impacts on the household's time allocation and the vehicle distance traveled (VDT). It is shown that most of the commute time saved is again put for more work and no more time could be allocated to leisure hours. In addition, when people put a high value on the work on site, the VDT may even increase.     

China and the Exports of Other Asian Countries

We analyze the impact of China’s growth on the exports of other Asian countries, distinguishing China’s demand for imports from its penetration of export markets. We account for the endogeneity of Chinese exports by applying instrumental variables in a gravity model with country-pair fixed-effects. We find that China’s crowding-out effect is felt mainly in markets for consumer goods and hence by less-developed Asian countries, not in markets for capital goods or by the more advanced Asian economies. Meanwhile, China has been sucking in imports from its Asian neighbors, but this effect is mainly felt in markets for capital goods. Hence, more and less developed Asian countries are being affected very differently by China’s rise. JEL no. E5, F4     

Does income inequality lead to banking crises in developing countries? Empirical evidence from cross-country panel data

This study empirically examines whether increasing income inequality results in banking crises using panel data for 68 countries covering the years 1973 to 2010. The results show that developing countries with high inequality tend to have higher levels of domestic credit and that domestic credit booms increase the probability of banking crises. We also find that developing economies display direct channels from inequality to banking crises without an association with credit booms. We find no consistent evidence that income inequality contributes to banking crises in advanced economies. In developing countries, the probability of banking crises increases dramatically as income inequality levels increase: The probability of a systemic banking crisis within three years is 9.5% when the Gini is as low as 0.2 in developing countries and increases to 57.4% when the Gini is 0.4. These results are robust to several specifications.     

Network Updating and Exploratory Learning Environment*

abstract This paper examines how the current relevance of social capital derived from a task‐advice network affects an actor's exploratory learning environment. Building on Burt's (1992 ) structural holes hypothesis that a large, sparse task advice network enhances an actor's exploratory learning environment, I propose that such effects hold only when the direct and indirect network ties are composed of current network contacts (ones that have been updated since the last change in positions of an actor). Analyses of data from a sample of 230 salaried employees of a high‐technology manufacturing corporation support my arguments. In addition to the focus of social capital research on network structure, therefore, this study emphasizes the time‐contingent value of social capital.     

Public service quality and customer satisfaction: exploring the attributes of service quality in the public sector

Beyond the existing SERVQUAL-based research, the authors develop an alternative model of public service quality. The various sources of public service quality are explored and a new classification scheme formulated by using critical incidents technique. Four main qualities of public service are identified: process quality, outcome quality, design quality, and relationship quality. The findings suggest that the critical attributes of public service quality for customer satisfaction differ according to the types of customers in the public sector. Final customers (beneficiaries) give priority to the process and outcome qualities, whereas intermediary customers (social workers) have high regard for the design and relationship qualities.     

RESTORING THE PRINCIPLE OF MINIMUM DIFFERENTIATION IN PRODUCT POSITIONING

Most research on product positioning supports the idea of differentiation. Product standardization (i.e., minimum differentiation) occurs only under very limiting assumptions. Yet, similar products are often observed in the marketplace. We attempt to restore the case for standardization by using more realistic assumptions than in previous work. We assume that consumers consider not only observable attributes in brand choice, but also attributes that are unobservable by the firms. We find that standardization is an equilibrium when consumers exhibit sufficient heterogeneity along the unobservable attributes under both positioning with exogenously given prices and price competition, We also show that, under insufficient heterogeneity along the unobservable attribute, our results coincide with past research that argues in favor of differentiation.     

Including the effects of prior and recent contact effort in a customer scoring model for database marketing

Database marketers often use a scoring model to predict the likely value of contacting customers based on their purchase histories and demographics. However, when purchase history has been a partial result of the firm’s own contacting efforts, these contacts should also be accounted for in the scoring model. The current work extends the existing literature to account for the firm’s contacts by focusing on each customer’s most recent purchase. Contacts prior to that purchase are designated “prior contacts” and those after that purchase “recent contacts.” A new latent variables formulation of the customer’s propensity to respond is used to predict the likelihood and time of response as well as the relationship to the independent variables. The methodology also addresses the statistical problems of “selection bias” and “endogeneity,” which have been largely ignored in most customer scoring models. An application to the database of a charitable organization confirms that, in this case: (1) the effect of the firm’s customer contact efforts is associated with a stronger propensity to respond than is the case for the included demographics; (2) the firm’s “recent contact” efforts are associated with larger returns in customers’ propensity to respond than the “prior contact” efforts; and (3) the “recent contact” efforts are associated with an at-first increasing but then diminishing propensity to respond up to a point beyond which actual decreasing returns are observed with further contacts. Clearly, too much contacting can alienate would-be donors. The proposed model is general enough to calibrate such impacts in other database marketing applications where the relative effects might be different.
