The effects of resale price maintenance laws on petrol prices and station attrition: empirical evidence from Wisconsin

The state of Wisconsin's Unfair Sales Act prevents the sale of any item below cost in order to attract business, and specifically requires petrol (gasoline) stations to mark up their prices by at least 6% over the wholesale price. While the ostensible reason for this law is to protect small, independent retailers and thus enhance competition, the evidence suggests that the primary result of this law has been to inflate the price of petrol for Wisconsin consumers and facilitate tacit collusion in retail petrol markets. Petrol prices in two major markets in the state are examined, as well as in one market outside of the state where no minimum markup is required. The data show that when the penalties for violating the Unfair Sales Act were strengthened, the average markup of retail petrol over the wholesale price increased significantly in Wisconsin without a commensurate change in the average markup in the market outside of Wisconsin. It is also found that price dispersion is significantly lower over a two-year period in the protected Wisconsin market than in the unprotected markets.     

Competitive Strategy,Environmental Characteristics and Performance in African Emerging Economies: Lessons from Firms in Ghana

ABSTRACT

This paper examines the impact of the implementation of competitive strategy on organizational performance in response to economic liberalization policies using survey data from organizations in Ghana. We also examine how the perceived intensity of industry competition and industry sector moderate the relationship between competitive strategy and organizational performance. The results show that the implementation of the competitive strategies of low-cost, differentiation, and integrated low-cost and differentiation were all positively related to performance (return on assets and return on sales). We also find that both industry competition and industry sector moderate the relationship between differentiation strategy and return on assets. Moreover, industry competition moderates the relationships between both low-cost and differentiation strategies and return on sales. The results indicate that implementing a clearly defined competitive strategy is beneficial to organizations experiencing significant changes in the environment due to economic liberalization. The findings also suggest that while low-cost strategy is more beneficial to organizations in a highly competitive industry, differentiation strategy is more beneficial to firms in lowly competitive industry. At the same time, organizations in the manufacturing sector benefit more than those in the service sector when they implement the differentiation strategy. Managerial implications are presented.     

The problem of the uninsured

The problem of the uninsured cannot be fully understood without considering the role of non-market alternatives to ‘market insurance’ called ‘self-insurance’ and ‘self-protection’ (SISP), including the public ‘health care safety-net’ system. We tackle the problem by formulating a ‘full-insurance’ paradigm that accounts for all four interacting insurance measures. We apply two versions of the full-insurance model to estimate, via calibrated simulations, the impacts of SISP on the fraction of uninsured, health spending, and health levels, and to assess how the mandated Affordable Care Act might affect these outcomes in comparison with the CBO projections in 2010. The results indicate that policy analyses which overlook the role of the real price of market insurance relative to the shadow prices of SISP in determining the decision to insure can grossly distort the capacity of mandated reforms like the ACA to insure the uninsured, contain overall health care costs, and improve health and welfare outcomes.     

Inflation Targeting Framework and Interest Rates Transmission in Ghana: An Empirical Investigation

This paper investigates the long-and short-run rate of transmission of the prime rate to interest rates since the implementation of inflation targeting policy in Ghana. Monthly data covering the period January 2002 to March 2016 is used. The Johansen and Hansen parameter instability cointegration, the FMOLS and DOLS estimation procedures were used. The long-run results show incomplete pass-through of the prime rate to commercial banks’ lending and deposit rates but over pass-through to the 91-day Treasury bill rate. The short-run adjustment shows relatively slow transmission of the prime rate to the respective interest rates. Given the findings, relevant policy suggestions are provided.     

Using Aggregate Time Series Variables to Forecast Notices of Default

This paper emphasizes the economic variables and data used to model notices of default in California. Forecast models are notoriously complicated and require sophisticated software to run. Few businesses, particularly small enterprises, have the necessary resources to engage in large-scale model building. Datasets can be difficult and expensive to obtain and usually require significant analysis. The paper focuses on methodology to give the model a general appeal.     

Specialized Careers

An agent has different abilities in two types of tasks. These tasks are revealed over time through his performance. The agent initially decides whether to engage in only one task (specialize) or to take on any task that arises (be a generalist). This decision trades off the cost of being idle against staying available for relatively lucrative tasks. We compare specializing with acting as a generalist in an infinite‐horizon model and provide complete characterizations of efforts. We show how specializing acts as a means of committing to exert more effort. In a two‐period version of the model, this implies that positive costs for switching strategies, through license fees, for example, may be socially desirable.     

Understanding visitor's motivation at sites of death and disaster: the case of former transit camp Westerbork,the Netherlands

This study begins to fill the gap in research of people's motivations to visit sites of death and suffering and to contribute to a deeper understanding of dark tourism consumption within dark conflict sites. The article aims to examine the motivations of visitors to former transit camp Westerbork as an iconic dark site in the Netherlands. The research process involved a self-administered survey questionnaire filled by 238, randomly selected Dutch visitors. Data are analysed by means of exploratory factor analysis to decide upon the relevant factors for representing the motivations of visitors to Westerbork. The findings show that people visit Westerbork mainly for ‘self-understanding’, ‘curiosity’, ‘conscience’, a ‘must see’ this place and ‘exclusiveness’. This is the first study to examine visitors’ motivations to Westerbork as a dark site. Most research on visitor motivations is not based on empirical data, but on theoretical research.     

Residential-Mortgage Lending Discrimination and Lender-Risk-Compensating Policies

The Boston Federal Reserve study ( Munnell et al. 1996 ) concluded that illegal discrimination is a statistically significant contributor to the observed gap between white and minority residential-mortgage rejection rates. The Boston study speculated that discrimination arises because lenders do not equally apply risk compensation or mitigation policies for imperfect loans. Using the same 1990 Boston loan application data, our study specifically examines the relation between compensating policies and discrimination. Since compensating policies are encouraged by secondary-mortgage-market sale guidelines, we model both the lender's origination decision and its loan sale decision. Using a rule-based artificial-intelligence technique applied to each lender, we infer compensating policies (rules) that equally apply to all races and explain lending decisions. A minority-race indicator loses its statistical significance when an indicator of compensating-policy violations appears in the loan accept–reject equation. This result reflects the fact that the risk levels of marginal minority loans tend to be more extreme than those of marginal white loans. However, the result does not necessarily reject the existence of discrimination. Equally applied policies may be empirically indistinguishable from unfairly applied policies. In addition, equally applied policies may fail the adverse-impact doctrine if they do not serve a business necessity (such as profits). The industry's move away from discretionary, rule-based decisions to mortgage scoring answers the need for a decision framework that rigorously uses loan performance to evaluate all loan applicants fairly.     

Something to prove: reputation in teams

Agents work for their own reputations when young but for their firms' when old. An individual with an established reputation cannot credibly commit to exerting effort when working alone. However, by hiring and working with juniors of uncertain reputation, seniors will have incentives to exert effort. Incentives for young agents arise from a concern for their own reputation (and the opportunity to take over the firm), whereas older agents work for the reputation of their firms (and the opportunity to sell out to juniors). Thus, the article explains the choice to work in teams. It also exemplifies how type uncertainty in reputation models may be endogenously and strategically introduced.
