Income Redistribution with Well-Informed Local Governments

This paper examines the problem of redistributing incomeacross jurisdictions and to mobile workers within jurisdictionswhen local governments have better information than the centralgovernment about local production conditions. Under the centralgovernments optimal policy, the subsidies or taxes that localgovernments provide to mobile workers normally depend on whetherthese governments are net recipients or net donors of interjurisdictionalincome transfers. Moreover, the public-input decisions of somelocal governments are distorted. The analysis demonstrates thatit may not be desirable to harmonize social policies across jurisdictions,even when the beneficiaries are quite mobile.     

Preventing HIV in injection drug users: exploring the tradeoffs between interventions

Injection drug users (IDUs) transmit the human immunodeficiency virus (HIV) via both needle sharing and sex. Available interventions for this population have varying costs and effectiveness and focus on different risk behaviors. In this analysis, we look at two interventions. One is inexpensive, broad-based and provides modest risk reductions (street outreach (SO)); the other is narrowly focused, expensive and relatively effective (methadone maintenance). This analysis explores the effects of population risk behavior, intervention effectiveness, intervention costs, and decision constraints when allocating funds between these two interventions to maximize effectiveness. We develop a model of the spread of HIV, dividing IDUs into susceptibles (uninfected) and infectives, and separately portraying sex and injection risk. We simulate the epidemic in New York City for time periods from the mid-1980s to the early 1990s, and incorporate the behavioral effects of two interventions performed singly or in combination to find the allocation that maximizes the number of infections averted in the IDUs and their noninjecting sex partners, assuming interventions have increasing marginal costs. We find that the optimal allocation nearly always involves spending the maximum allowable amount on SO. This result is largely insensitive to variations in risk parameters, intervention efficacy, or cost. The model's structure, however, makes clear that many factors contribute to this insensitivity, namely the scope of the interventions, the dual drug/sex nature of HIV risk in the population, the asymmetry of sexual risk for men and women, and the potential benefits to nonIDUs.     

Hard globalization

Many companies aspire to be players in the global marketplace, but the challenges to succeed are now greater than ever. Steve Tappin and Andrew Cave spoke with the CEOs of strongly globalized companies to learn their secrets.     

Airport regulation: Does a mature industry have mature regulation?

Air transport needs to be considered as a number of separate industries. Each is at their own point of maturity. Airports in Europe are soon to be regulated as never before by the European Airport Charges Directive. The process that saw that Directive be agreed is instructive on the maturity of the airport industry and the maturity of the regulatory regime that governs it. The new Directive shows that regulation of the airport industry is maturing.     

Factors Influencing Consumer Acceptance of Mobile Marketing: A Two-Country Study of Youth Markets

The purpose of this study is to examine factors affecting consumers' acceptance of mobile marketing across two global markets. Drawing upon technology acceptance and uses and gratifications theories, we develop and estimate a conceptual model of the influences of antecedent factors (including risk acceptance related to the mobile platform and personal attachment related to mobile devices) on behavioral intent related to mobile marketing practice. We further propose that the above relationships are mediated by activities that consumers engage in such as downloading, forwarding content and registering with firms. Focusing on youth consumers, we empirically test the model using data collected in both an established (U.S.) and an emerging market (Pakistan). Findings across these two markets reflect cross-market similarities and differences related to consumer acceptance factors. We draw implications from these findings related to both theory and practice.     

Reversing the Logic: The Path to Profitability through Relationship Marketing

Many firms have experienced greater success through implementing relationship marketing strategies. This is achieved by gaining knowledge about their own customers through database marketing and about the general marketplace through marketing research. Over time, this has led firms to adopt a general framework which we call the conventional path to profitability. This conventional framework suggests that new product innovation leads to acquisition, acquisition combined with a rich experience leads to satisfaction, satisfaction leads to loyalty and customer retention, and loyalty/retention leads to profitability. However, we show that some of the links in the framework are weak based on both academic research and marketplace realities. Consequently, we reverse the logic of the conventional path to profitability. We introduce a new approach that starts the customer relationship management strategy with customer profitability and the notion that different customers should be rewarded and satisfied differently. In addition, we outline a strategy that relationship marketing firms can implement, leading to higher levels of customer profitability and offer directions for future research.     

Financial competence,overconfidence, and trusting investments: Results from an experiment

Financial transactions sometimes occur in an environment where third-party enforcement is lacking. Behavioral explanations typically allude to the social preferences, where an individual’s utility is directly affected by another’s outcome, as the driver of the trusting investments and reciprocal returns. We hypothesize that, in part, these decisions are determined by an individual’s financial literacy and overconfidence in one’s knowledge. Experimental evidence is coupled with an innovative financial literacy assessment, which measures general competence, numeracy skills, and overconfidence in one’s knowledge. Results indicate that overconfidence is a significant determinant of behavior. Specifically, overconfident individuals make larger contributions in the investment game. We also document that there is an escalated effect in overconfident individuals who are also exhibit risk loving preferences.     

Variable reduction,sample selection bias and bank retail credit scoring

This paper investigates the effect of including the customer loan approval process to the estimation of loan performance and explores the influence of sample selection bias in predicting the probability of default. The bootstrap variable reduction technique is applied to reduce the variable dimension for a large data-set drawn from a major UK retail bank. The results show a statistically significant correlation between the loan approval and performance processes. We further demonstrate an economically significant improvement in forecasting performance when taking into account sample selection bias. We conclude that financial institutions can obtain benefits by correcting for sample selection bias in their credit scoring models.
