Domestic airline alliances and consumer welfare

This article investigates the consumer welfare consequences of the recent code‐share agreement between Continental Airlines and Northwest Airlines. We develop a discrete choice model based on individual flight characteristics. This structural model recognizes that consumers (i) may have heterogeneous preferences for flight attributes, and (ii) may face different prices for the same flight. The empirical methodology also deals with the measurement error problem stemming from the absence of consumer‐level data on prices. The estimation results suggest that, whereas the code‐share agreement did not impact consumers significantly on average, it increased the average surplus of connecting passengers but decreased the average surplus of nonstop passengers. Interestingly, the magnitude of our welfare results may be attributed in large part to changes in product characteristics other than prices.     

Demand estimation and consumer welfare in the banking industry

This paper estimates a structural demand model for commercial bank deposit services in order to measure the effects on consumers given dramatic changes in bank services throughout US branching deregulation in the 1990s. Following the discrete choice literature, consumer decisions are based on prices and bank characteristics. Consumers are found to respond to deposit rates, and to a lesser extent, to account fees, in choosing a depository institution. Moreover, consumers respond favorably to the branch staffing and geographic density, as well as to the bank’s age, size, and geographic diversification. Consumers in most markets experience a slight increase in welfare throughout the period.     

Insurer pricing and consumer welfare: evidence from Medigap

This article examines the welfare impact of imperfect competition in the Medicare supplement insurance (Medigap) market. Two firms control nearly three fourths of the Medigap market, and premiums exceed claims by over 25%. I find that a low price elasticity and consumers' brand preferences lead firms to engage in substantial marketing and price above cost. Therefore, the strategic behavior of insurers facing relatively inelastic demand is critical in explaining poor market performance. I also find that insurers do not capture all of the rents in this market; rents also accrue to actors who perform marketing functions, including agents and brokers.     

The impact of soda taxes on consumer welfare: implications of storability and taste heterogeneity

The typical analysis on the effectiveness of soda taxes relies on price elasticity estimates from static demand models, which ignores consumers' inventory behaviors and their persistent tastes. This article provides estimates of the relevant price elasticities based on a dynamic demand model that better addresses potential intertemporal substitution and unobservable persistent heterogeneous tastes. It finds that static analyses overestimate the long‐run own‐price elasticity of regular soda by 60.8%, leading to overestimated consumption reduction of sugar‐sweetened soft drinks by up to 57.9% in some cases. Results indicate that soda taxes will raise revenue but are unlikely to substantially impact soda consumption.     

The disclosure of corporate social responsibility reports and sales performance in China

Based on legitimacy and stakeholder theory, we investigate whether there is an association between the disclosure of corporate social responsibility reports and a firm's sales performance in China. The empirical results reveal that the return on sales and sales growth are positively associated with the level of corporate social responsibility reporting in China. This positive association is strengthened when firms have concentrated customers. Firms use corporate social responsibility reports to improve sales performance and attract customers, who are one of their major stakeholders, and retain their legitimacy.     

Prominence and consumer search

This article examines the implications of “prominence” in search markets. We model prominence by supposing that the prominent firm will be sampled first by all consumers. If there are no systematic quality differences among firms, we find that the prominent firm will charge a lower price than its less prominent rivals. Making a firm prominent will typically lead to higher industry profit but lower consumer surplus and welfare. The model is extended by introducing heterogeneous product qualities, in which case the firm with the highest‐quality product has the greatest incentive to become prominent, and making it prominent will boost industry profit, consumer surplus, and welfare.     

Banking competition and welfare

We develop a simple general equilibrium model in which investment in a risky technology is subject to moral hazard and banks can extract market power rents. We show that more bank competition results in lower economy-wide risk, higher social welfare, lower bank capital ratios, more efficient production plans and Pareto-ranked real allocations. Perfect competition supports a second best allocation and optimal levels of bank risk and capitalization. These results are at variance with those obtained by a large literature that has studied a similar environment in partial equilibrium, they are empirically relevant, and carry significant implications for policy guidance.     

Sales and consumer inventory

Temporary price reductions (sales) are common for many goods and naturally result in a large increase in the quantity sold. We explore whether the data support the hypothesis that these increases are, at least partly, due to demand anticipation: at low prices, consumers store for future consumption. This effect, if present, has broad economic implications. We test the predictions of an inventory model using scanner data with two years of household purchases. The results are consistent with an inventory model and suggest that static demand estimates may overestimate price sensitivity.     

Some effects on information load on search patterns used to analyze performance reports

This paper contains a framework within which to describe how the amount of information in a performance report impacts on a manager's report analysis process. Generally, the data collected from experienced managers as they analyzed performance reports were not completely supportive of the framework based hypotheses. An explanation is presented to account for the discrepancies. Future research could use this explanation to describe further how managers analyze performance reports.     

Signaling strategies in annual reports: Evidence from the disclosure of performance indicators

In voluntary annual report communication, empirical results of signaling theory are contrasting, mainly owing to problems in disclosure measurements. We focus on a specific piece of incremental information and study the signaling strategies in annual reports by analyzing the disclosure of performance indicators that provide incremental information. In this paper, we scrutinize the business review of a sample of 120 listed Italian companies for fiscal year 2010. After controlling for size, risk, and industry, our analysis confirms that the number of indicators published is positively related to firm profitability. Our results help clarify the signaling strategies in annual report communication. Operatively, our evidence can help regulators and standard setters to better discipline the communication of relevant and private information in annual reports, particularly performance indicators.     

Debt relief schemes and welfare

This paper shows that concerted debt reduction may be welfare-improving even when the investment disincentive effect of a debt overhang is not large enough to place the debtor country on the wrong side of the debt Laffer curve. Whether the appropriate relief scheme involves debt reduction or new money, however, depends on whether investment disincentives or liquidity constraints dominate. It is shown that, except under very special circumstances, mixed policy packages involving both debt and liquidity relief may not yield the desired results. (JEL F34).     

Stakeholder welfare and firm value

Using data from the independent social choice investment advisory firm Kinder, Lydenberg, Domini (KLD), we construct a stakeholder welfare score measuring the extent to which firms meet the expectation of their non-shareholder stakeholders (such as employees, customers, communities, and environment), and find it to be associated with positive valuation effects: an increase of 1 in the stakeholder welfare score leads to an increase of 0.587 in Tobin’s Q. Furthermore, the valuation effects vary across stakeholders and the aforementioned positive effects are driven by firms’ performance on employee relations and environmental issues. These results suggest that stakeholder welfare (in particular, employee welfare and environmental performance) represents intangibles (such as reputation or human capital) crucial for shareholder value creation rather than private benefits managers pursue for their own social or economic needs.

Politicizing consumer credit

Powerful politicians can interfere with the enforcement of regulations. As such, expected political interference can affect constituents’ behavior. Using rotations of Senate committee chairs to identify variation in political power and expected regulatory relief, we study powerful politicians’ effect on consumer lending to communities protected by fair-lending regulations. We find a 7.5% reduction in credit access to minority neighborhoods in states with new committee chairs. Larger reductions occur in Community Reinvestment Act-eligible neighborhoods and when Senators serve on committees that oversee the enforcement of fair-lending laws. Banks headquartered in powerful Senators’ states are responsible for the reduction in credit access.     

Asset price bubbles and economic welfare

In this paper, we provide the first empirical evidence on whether or not asset price bubbles predict economic welfare. Using a time-series model, we show that asset price bubbles both positively and negatively predict economic welfare, although the evidence that asset price bubbles are welfare-enhancing is much stronger. These results are also robust to out-of-sample forecasting as well as to a predictive regression model augmented by structural break dates.     

Insurance loss coverage and social welfare

Restrictions on insurance risk classification may induce adverse selection, which is usually perceived as a bad outcome, both for insurers and for society. However, a social benefit of modest adverse selection is that it can lead to an increase in ‘loss coverage’, defined as expected losses compensated by insurance for the whole population. We reconcile the concept of loss coverage to a utilitarian concept of social welfare commonly found in the economic literature on risk classification. For iso-elastic insurance demand, ranking risk classification schemes by (observable) loss coverage always give the same ordering as ranking by (unobservable) social welfare.     

Payday loans and consumer financial health

The annualized interest rate for a payday loan often exceeds 10 times that of a typical credit card, yet this market grew immensely in the 1990s and 2000s, elevating concerns about the risk payday loans pose to consumers and whether payday lenders target minority neighborhoods. This paper employs individual credit record data, and Census data on payday lender store locations, to assess these concerns. Taking advantage of several state law changes since 2006 and, following previous work, within-state-year differences in access arising from proximity to states that allow payday loans, I find little to no effect of payday loans on credit scores, new delinquencies, or the likelihood of overdrawing credit lines. The analysis also indicates that neighborhood racial composition has little influence on payday lender store locations conditional on income, wealth and demographic characteristics.     

Price incentives and consumer payment behaviour

In this paper we estimate the effect of particular price incentives on consumer payment patterns using transaction-level data. We find that participation in a loyalty program and access to an interest-free period tend to increase credit card use at the expense of alternative payment methods, such as debit cards and cash. Interestingly though, the pattern of substitution from cash and debit cards differs according to the price incentive. An implication of the findings is that the Reserve Bank reforms of the Australian payments system are likely to have influenced observed payment patterns.
