Identification and estimation of Gaussian affine term structure models

This paper develops new results for identification and estimation of Gaussian affine term structure models. We establish that three popular canonical representations are unidentified, and demonstrate how unidentified regions can complicate numerical optimization. A separate contribution of the paper is the proposal of minimum-chi-square estimation as an alternative to MLE. We show that, although it is asymptotically equivalent to MLE, it can be much easier to compute. In some cases, MCSE allows researchers to recognize with certainty whether a given estimate represents a global maximum of the likelihood function and makes feasible the computation of small-sample standard errors.     

To Screen or Not to Screen? Using the Internet for Selection Decisions

Organizations are increasingly relying on Internet searches and social networking websites to uncover detailed and private information about job applicants. Such Internet screening techniques have the potential to provide additional information beyond that found using traditional screening approaches. However, questions regarding the legality and appropriateness of this practice, as well as issues regarding the standardization, reliability, and validity of the information obtained, need to be addressed. The current work describes these issues associated with Internet screening and provides recommendations to help ensure this practice is used appropriately in organizations. Suggestions for future research on Internet screening are also discussed.     

Arrival Cohort, Assimilation, and the Earnings of Caribbean Women in the United States

Utilizing data on U.S.-born and Caribbean-born black women from the 1980–2000 U.S. Censuses and the 2000–2007 waves of the American Community Survey, I document the impact of cohort of arrival, tenure of U.S. residence, and country/region of birth on the earnings and earnings assimilation of black women born in the English-, French-, and Spanish-speaking Caribbean. I also test whether selective migration accounts for earnings differences between U.S.-born and Caribbean-born black women in the United States. I show that almost all arrival cohorts of Caribbean women earn less than U.S.-born black women when they first arrive in the United States. However, over time the earnings of early arrival cohorts from the English- and French-speaking Caribbean are projected to surpass the earnings of U.S.-born black women. Indeed, this crossover is most pronounced for women from the English-speaking Caribbean. In models that account for selective migration by comparing the earnings of Caribbean women to U.S.-born black women who have moved across states since birth, I show that more time is required for early arrival cohorts from the English- and French-speaking Caribbean to surpass the earnings of U.S.-born black internal migrants. Women from the Spanish-speaking Caribbean do not seem to experience earnings growth as their tenure of U.S. residence increases. In summary, the findings suggest that selective migration is an important determinant of earnings differences between U.S.-born black women and black women from the Caribbean.     

Consumer substitution decisions: an integrative framework

Substitution decisions have been examined from a variety of perspectives. The economics literature measures cross-price elasticity, operations research models optimal assortments, the psychology literature studies goals in conflict, and marketing research has examined substitution-in-use, brand switching, stockouts, and self-control. We integrate these perspectives into a common framework for understanding consumer substitution decisions; their specific drivers (availability of new alternatives, internal vs. external restrictions on choice); the moderating role of a consumer’s commitment to an initially desired alternative; and the affective, motivational, cognitive, and behavioral outcomes of substitution. We use this framework to recommend new avenues for research.     

Optimal Tax Theory: The Journey from the Negative Income Tax to the Earned Income Tax Credit

What lessons do we learn from optimal tax theory for the design of income redistribution programs? I modify a standard model of optimal nonlinear income taxation with discrete types to consider differences in both earning ability and the disutility of effort. This gives a role for “workfare” in the optimal tax policy. The existence of screening mechanisms can play a role in explaining non‐participation in cash and in‐kind redistribution programs, including Progresa‐Oportunidades, Lifeline Telephone subsidies, and the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). Stigma can increase efficiency of a redistribution program by discouraging participation by individuals near the eligibility thresholds. The Family Assistance Program proposed in the early 1970s lacked adequate stigma for nonworkers, which contributed to a lack of political support. In contrast, the current Earned Income Tax Credit (EITC) provides greater benefits to workers than to nonworkers. Thus the EITC does not require any stigma to screen out individuals who do not work from obtaining benefits. Reasons for separate income support programs for nonworkers and for workers are discussed.     

The Third Policeman: ‘The true and fair view’, language and the habitus of accounting

This paper explores the role and context of the ‘true and fair view’ (‘TFV’) in accounting and auditing. Utilising the work of Bourdieu as a lens, the paper argues that the world of the TFV is a subjective world with which we think we are objectively familiar. Bourdieu's ‘practical theory’ of habitus suggests that the TFV is shaped by the practice of ‘native virtuosos’ who have a ‘feel for the game’. The paper argues that the conceptualisation of the TFV privileges practice and authenticates the accounting habitus. Hence, whilst language maintains and reinforces social structures, it is in turn created by the routines of practice. By dominating the declaration of the TFV, the auditor effectively reinforces the status quo and the constitution of hierarchy and inequity that exists in the accounting field: the TFV, in Bourdieu's terms, ‘becomes what they are’.     

Toward a theory of customer engagement marketing

Customer engagement marketing—defined as a firm’s deliberate effort to motivate, empower, and measure customer contributions to marketing functions—marks a shift in marketing research and business practice. After defining and differentiating engagement marketing, the authors present a typology of its two primary forms and offer tenets that link specific strategic elements to customer outcomes and thereby firm performance, theorizing that the effectiveness of engagement marketing arises from the establishment of psychological ownership and self-transformation. The authors provide evidence in support of the derived tenets through case illustrations, as well as a quasi-experimental field test of the central tenet of engagement marketing.     

SO2 policy and input substitution under spatial monopoly

Following the U.S. Clean Air Act Amendments of 1990, electric utilities dramatically increased their utilization of low-sulfur coal from the Powder River Basin (PRB). Recent studies indicate that railroads hauling PRB coal exercise a substantial degree of market power and that relative price changes in the mining and transportation sectors were contributing factors to the observed pattern of input substitution. This paper asks the related question: To what extent does more stringent SO₂ policy stimulate input substitution from high-sulfur coal to low-sulfur coal when railroads hauling low-sulfur coal exercise spatial monopoly power? The question underpins the effectiveness of incentive-based environmental policies given the essential role of market performance in input, output, and abatement markets in determining the social cost of regulation. Our analysis indicates that environmental regulation leads to negligible input substitution effects when clean and dirty inputs are highly substitutable and the clean input market is mediated by a spatial monopolist.
