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.     

‘Shopping for Voice’: Do Pre‐Existing Non‐Union Representation Plans Matter When Employees Unionize?

The transition to unionization in three workplaces with pre‐existing non‐union employee representation plans (NERPs) is contrasted to three matched sites, which had only individual representation. Pre‐existing collective voice arrangements had substantial effects on the process and outcomes of unionization. While the individual representation sites presented a conventional process of mobilization and attachment to the union, the NERP sites revealed a more equivocal outcome. The union was used in an instrumental manner to increase NERP power and to achieve worker demands already articulated by the NERP. NERP leaders became union leaders. There remained significant attachment to the NERP and a reluctance to fully embrace unionization.     

The Endless Day: The Political Economy of Women and Work

Few critics will question that the high tide of the influence of American institutional economics was reached during the New Deal. John R. Commons, Thorstein Veblen and their disciples reached the apex of their impact on public policy as sources of doctrine, policy-making and advising. Commons remains an influential figure in the history of institutional economics and progressive social thought. And he resides in the American tradition of empirical collectivism as articulated by Currin V. Shields in 1952. The tradition as understood by Commons finds the ultimate locus of power in democratic majorities, not in hegemonic classes or corporate networks, and it is only by its refinement and replenishment that it can meet the demands thrust upon it. His mature theoretical work, published between 1924 and 1950, is the main source of his empirical collectivism as shown through textual exegesis and biographical extrapolation.     

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’.     

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.     

The Impact of the NHS Reforms on Queues and Surgical Outcomes in England: Evidence From Hip Fracture Patients

National Health Service (NHS) reform introduced incentives for efficiency and cost effectiveness, yet little is known about their effectiveness in reducing waiting times for surgery or improving post-surgical outcomes. This paper finds that waiting times for hip fracture surgery declined after the NHS reforms, and patients were more likely to be discharged to another provider. However, hospitals have not simply shifted the burden of care to other providers, since lengths of stay ending in a discharge to home fell. The effect of wait time on surgical outcomes is small in magnitude and cannot explain the post-reform improvements in outcomes.
