Pensions: theories of underfunding

The widespread underfunding of private defined benefit pensions has generated concern over the viability of employers' promises of retirement benefits. Years ago, similar concerns led to the creation of pension benefit insurance plans by governments in the United States and a number of other countries. This paper studies the causes of underfunding in an environment without pension benefit insurance. We find that the optimal level of retirement benefits will be offered and fully funded if the employer has sufficient internal funds or is able to borrow all it needs. If loans are not enforceable, an employer with limited resources will generally underfund pensions. Further, if pension investments earn lower returns than other investments, pensions will be underfunded. Thus, the paper highlights the link between financial markets and the underfunding of pensions.     

Changing Behaviour: Successful Environmental Programmes in the Workplace

There is an increasing focus on improving the pro‐environmental attitudes, behaviour and habits of individuals, whether at home, in education, travelling, shopping or in the workplace. This article focuses on the workplace by conducting a multi‐disciplinary literature review of research that has examined the influence of organization‐based behaviour change initiatives. The review includes only research evidence that measured actual environmental performance (e.g. energy use) rather than solely using self‐reported methods (e.g. questionnaires). The authors develop an ‘employee pro‐environmental behaviour’ (e‐PEB) framework, which contains individual, group, organizational and contextual factors that have predictive relevance across different behaviours and organizations. The review shows that the strongest predictors are environmental awareness, performance feedback, financial incentives, environmental infrastructure, management support and training. A key finding from this review is that attitude change is not necessarily a pre‐requisite for behaviour change in the workplace. Copyright © 2013 John Wiley & Sons, Ltd and ERP Environment     

Non-stationary inflation and panel estimates of United States short and long-run Phillips curves

This paper argues that because United States inflation has been non-stationary over the past five decades the vast body of empirical research that proceeds without adequately accounting for the non-stationarity in the data is invalid. Using 50 years of United States inflation data the standard results in the Phillips curve literature are shown to be due to unaccounted shifts in the mean rates of inflation over the period. Short and long-run Phillips curves for the United States are then estimated using time series panel data techniques that account for these shifts in mean.     

Commitment and the adoption of a common currency*

In contrast to Mundell's inquiry on the optimality of currency areas, this article aims to understand under what circumstances a Pareto‐dominant monetary union will be established. Using a multicountry overlapping generations model, we highlight gains from monetary union arising from reduced transactions costs and lower inflation. Despite these gains, countries acting independently will impose barriers to exchange through local currency restrictions, thereby creating transactions costs and providing an incentive for inflation. Therefore, the gains from monetary union are most likely to be lost without collective effort.

Fee or free checking? Noninterest checking account fees,competition and multimarket banking

This article analyses noninterest checking (NIC) account fees using a unique data set covering 11 875 observations on 1880 banks from 2008 to 2012. These data identify whether the bank has free or fee checking on NIC accounts and, where relevant, the fee and minimum balance to avoid the fee. Appealing to shrouded equilibrium theory, we hypothesize that banks, and particularly small banks, will avoid drawing the attention of myopic, low-income types by having stable policies, or will attempt to confuse depositors with contradictory policy shifts in the fee and minimum balance requirements. Competition and small bank size should favour consumers, but the meaning of ‘favour’ is complicated by large depositors and the banks subsidizing small depositors with NIC accounts.

The results support the avoid attention hypothesis, particularly for single-market banks, and weakly support the confuse depositors hypothesis. The largest banks, including three too big to fail banks, are most responsive to competition, with single-market banks far less responsive. Competition may be responsible for a dramatic decline in free checking among the largest banks, and substantial increases in minimum balances for those banks, since these effectively reduced subsidies. Simultaneously, single-market banks became more likely to offer free checking.     

Treatment patterns and predictors of costs among patients with migraine: evidence from the United States medical expenditure panel survey

Abstract

Aim: Within a treated migraine population, to evaluate if the sub-group meeting criteria for high disease-specific total costs is significantly different to the sub-group with medium and/or low-costs, and to identify the associated risk factors.

Methods: Data from the Household Component of Medical Expenditure Panel Survey (MEPS-HC, 2008–2012), a nationally representative survey of non-institutionalized civilians in the US, were analyzed. Key inclusion criteria were migraine diagnosis (ICD-9 code: 346.XX) and prescribed treatment for migraine. Patients were categorized into high (>top 10th percentile), low (<bottom 10th percentile), and medium (between high and low) cost sub-groups per migraine-specific total costs. Logistic regression models were applied to identify predictors of high vs medium and medium vs low-costs. Preventive eligibility, defined as (i) past/current use of migraine preventives or (ii) overuse of acute medications, was compared to non-preventive eligibility.

Results: Within the treated migraine cohort (n?=?1,735), the mean age was 39?years, 80% were female, and the majority were in the medium-cost sub-group (n?=?1,360) (low-cost n?=?190, high-cost n?=?195). Significant predictors of high vs medium-costs were low SF-12 Physical Composite Scores (OR?=?0.95; 95% CI?=?0.92–0.97), low SF-6D health utility index scores (OR?=?0.019; 95% CI?=?0.002–0.193), preventive eligibility-i (OR?=?0.019; 95% CI?=?0.002–0.193), and preventive-eligibility-ii (OR?=?3.10; 95% CI?=?1.62–5.91). Statistically significant (p?<?0.05) predictors of medium vs low-costs included anxiety, Fleishman score, preventive-eligible-i, and preventive-eligible-ii.

Conclusions: Among patients treated for migraine, distinct characteristics, including patient-functioning measures and comorbidities, are predictive of high vs medium-costs, and medium vs low-costs. Preventive eligibility is a predictor of being in the higher cost sub-groups; however, preventive treatments that improve functioning and reduce acute medication use have the potential to reduce migraine-specific costs.

Limitations: The results are limited to a population that is diagnosed and treated for migraine. Over-the-counter medication use, and migraine headache frequency and severity were not captured.
