Due to extremely low interest rates and the volatility of equity markets, over the past several years many DB pension plans have suffered significant solvency deficits. As a result, plan sponsors have sought relief from higher contributions required under pension laws. Temporary relief measures granted in certain jurisdictions have not addressed the underlying issues but have provided merely short-term solutions. At the other end of the spectrum, DC plans incorporate both predictable contributions and an alignment of risk and reward for plan members, but they leave complicated investment decision-making to plan members who frequently have no investment expertise. Furthermore, DC plans fail to capture substantial value available from pooling of costs, investment risk and longevity risk among plan members. We need to move beyond the DB versus DC debate towards a middle-ground option that incorporates some of the positive attributes of both designs. Target-benefit plans (TBPs) can deliver the cost predictability of DC plans combined with a defined-benefit-type pension to retirees, with predictable contribution levels, and enable pooling of longevity and investment risks. This Commentary reviews the recent New Brunswick shared risk pension legislation and draws lessons that can be applied to the design of similar TBP legislation elsewhere. In most Canadian jurisdictions, pension laws do not currently accommodate single-employer TBPs – although several provinces have taken initial steps. Existing legislation generally prohibits reduction of accrued benefits outside of the multi-employer unionized environment, and a key element of TBPs is their ability to let benefits vary as a function of the funding status of the plan. Tax rules must be changed to accommodate single-employer TBPs. As well, clear and logical accounting guidance for TBPs must be established to facilitate the emergence of such plans. Also, a jurisdictions wishes to permit conversion of accrued benefits to target benefits, legislative change is required. In New Brunswick, accrued benefits may be converted, which can promote intergenerational equity. Pension standards laws across the country will have to be changed in order to facilitate the emergence of new design options such as single-employer TBPs.","PeriodicalId":76903,"journal":{"name":"Employee benefits journal","volume":"40 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2014-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78840382","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accountable Care Organizations: A Balancing Act 问责保健组织:平衡法案

{"title":"Accountable Care Organizations: A Balancing Act","authors":"Jerry A. Johnson","doi":"10.2139/SSRN.2457584","DOIUrl":"https://doi.org/10.2139/SSRN.2457584","url":null,"abstract":"In 2010, the Patient Protection and Affordable Care Act (ACA) was signed into law by President Barack Obama. The ACA has three fundamental goals: (1) Increase access to health care; (2) Reduce the cost of health care; and (3) Improve the quality of health care. To reduce costs and improve quality, section 3022 of the ACA promotes the formation and operation of Accountable Care Organizations (ACOs) to treat Medicare beneficiaries in the new Medicare Shared Savings Program (SSP). ACOs are made up of competing health care providers collaborating to deliver efficient, coordinated care that meets quality performance and cost-saving standards that are determined by the Centers for Medicare and Medicaid Services (CMS). ACOs may take many forms, “including networks of individual practices, partnerships, hospitals, [joint ventures] and other health care professionals.” The ACA hopes to encourage new innovative delivery models and does not place heavy restrictions on the form or type of entity sufficient to gain the status of ACO.“It is expected that most health care providers that form ACOs for Medicare beneficiaries will also seek to use the ACO structure for their commercially-insured patients.” In order to produce cost-saving efficiencies, ACOs will look to negotiate contracts between their participating providers, including price terms. ACOs negotiating with private payers raises antitrust concerns over possible price fixing and exercise of market power to restrain trade. ACO practices that restrain trade would undermine the ACA’s attempt to reduce costs and improve quality by further impairing the health care market and harming consumers/patients.In 2011, CMS published the final rule implementing section 3022 of the ACA which creates the Medicare Shared Savings Program and encourages the creation of ACOs. The Department of Justice and the Federal Trade Commission are the two government agencies charged with enforcing antitrust law. The Federal Trade Commission and the Department of Justice have recently published guidance laying out antitrust enforcement as it relates to Accountable Care Organizations.There are three significant developments that flow from the guidance: 1) ACOs engaged in joint price negotiations with commercial health plans will be treated under the “rule of reason” if the ACO meets CMS’ eligibility standards for SSP participation; 2) ACOs that control up to 30% of market shares in any of its “common services” will be protected by a “safety zone” which shields the ACO from antitrust challenge absent extraordinary circumstances and 3) the Federal Trade Commission and the Department of Justice scrapped a mandatory review of ACOs that might wield market power and replaced it with a voluntary review process that can help ACOs that fall outside the safety zone to better assess its chances of raising antitrust concerns.As mentioned, collaboration between competing providers in ACOs raises antitrust concerns that providers may engage in ho","PeriodicalId":76903,"journal":{"name":"Employee benefits journal","volume":"85 5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2014-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89343448","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We estimate that about 1 million workers earn an income by main occupation in the neighborhood of the minimum wage. Findings show that the minimum wage-income elasticity is statistically significant; the evidence also suggests that those who receive low incomes and those working in small businesses are the most affected by increases in the minimum wage. Employment effects are monotonically decreasing in absolute terms by firm size: they are moderate in large firms and higher in small firms. Results are robust when assessing the job-to-job transitions. Finally, we present evidence that supports the hypothesis that the minimum wage in Peru is correlated with income. The movement of income distribution in the context of changes in the minimum wage and the results provided by a model that captures the drivers of income justify this finding.","PeriodicalId":76903,"journal":{"name":"Employee benefits journal","volume":"51 4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2014-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91012414","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Implementing The Capitalism/Socialism Cycle – Phase II – Melting the Excessive Executive Compensation Employee Stock Option Icebergs, [we refer to this work as “Iceberg”] the author zeroes in on twelve irregularities of employee stock options or ESOs, the workhorse of FC as suggested in the First Article, the correction of which are a starting point in the conversion of FC to TC. This paper is the second installment in a trilogy that will conclude with a third paper that will offer remedies to our economic system against the backdrop of the social and cultural values of the American Experience. There is a suggestion then in this offering that there is an extraordinary amount of direct and indirect information about ESOs that is unseen and therefore virtually unknown across the multiple disciplines attendant to this critical form of stock-based compensation. It also introduces the question of how so much important information necessary for the efficient and effective functioning of this important financial instrument of capitalism could be so conveniently overlooked. It is overlooked, in large part, because it is in the best interests of those plying their trade to overlook them. Iceberg discusses twelve of its own, i.e., important ESO issues that are there but whose existence currently enjoys some type of artful or elusive status. Briefly, they are: 1. ESO taxation at grant – the U.S. Treasury vs. the Taxpayer; 2. Robinson v. U.S. [2003] – a major retrofit of Internal Revenue Code §83 (“IRC§83”); 3. Insider use of listed, exchange-traded options (“LETOs”); 4. SEC Release No. 34-60126 [June 17, 2009]; 5. The Transferable Stock Option or TSO; 6.

Medicare provides a subsidy, based on a \"benchmark payment rate\", for each Medicare beneficiary a plan enrolls. We investigate how this subsidy, the primary policy lever in the market, affects the equilibrium premiums and benefits of MA plans. We exploit variation in benchmark payment rates within plans over time, coming from rebasing years where benchmark changes differed across areas in ways that were plausibly exogenous, to determine empirically how plan premiums and benefit generosity respond to changes in benchmarks. We find that premiums do not respond to changes in the benchmark payment rate on average but that insurers do pass through a portion of the benchmark increase by increasing plan benefit generosity. We argue that the way premium information is communicated to consumers influences the way in which plans pass through subsidy dollars and can account for the empirical results. More specifically, institutional features make it difficult for consumers to observe a large component of the plan premium, leading to a lack of demand response to premium reductions below the premium charged by traditional Medicare (the fee-for-service Part B premium). When demand does not respond to lower premiums, plans have an incentive to pass-through cost subsidies to consumers via more generous benefits that consumers may not value at cost, creating an inefficiently high level of benefit generosity. Our results provide evidence that a lack of premium transparency in the MA market may distort the combination of premium levels and benefit generosity offered in equilibrium, resulting in some degree of inefficiently high benefits. We conclude by discussing changes to the choice environment that would increase premium transparency and potentially soften the premium rigidities we find.","PeriodicalId":76903,"journal":{"name":"Employee benefits journal","volume":"29 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2014-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78619348","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study uses the Urban Institute’s DYNASIM model to estimate the effects of including ESI premiums in taxable earnings on the level and distribution by age and income groups of income tax burdens, payroll tax burdens, and OASDI benefits. We find that the increased present value of OASDI benefits from including ESI in the wage base in 2014 offsets about 22 percent of increased income and payroll taxes, 57 percent of increased payroll taxes, and 72 percent of increased OASDI taxes. The overall distributions of taxes and benefits by income group follow the same pattern, with both taxes and benefits increasing as a share of income between the bottom and middle quintiles and then declining as a share of income for higher income taxpayers. But households in the bottom income quintiles receive a net benefit from including ESI in the tax base because their increase in OASDI benefits exceeds their increase in income and payroll taxes. Over a lifetime perspective, all earnings groups experience net tax increases, but workers in the middle of the earnings distribution experience the largest net tax increases as a share of lifetime earnings. Higher benefits offset a larger share of tax increases for lower than for higher income groups.","PeriodicalId":76903,"journal":{"name":"Employee benefits journal","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2014-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88171949","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the alternative partial retirement scenario, individuals work part-time for several years before they stop working. For the individual, partial retirement provides a smooth transition to full-retirement where they gradually adjust to a possibly lower income and more leisure time in full-retirement, and for the economy, it is a potential policy tool to keep people employed longer. The models developed to explain the retirement decisions of older workers are typically estimated using data on actual retirement behavior, from which it is difficult to identify the retirement options available to employees. In particular, employers often do not provide partial retirement opportunities. In this paper, we use stated preference data to identify the preferences of individuals for full and partial retirement plans. We consider a choice set of hypothetical full and partial retirement plans and ask the respondents of a survey representative for the US population of ages 40 and over to choose their favorite plan. We analyze how the choices vary with financial incentives and other factors.","PeriodicalId":76903,"journal":{"name":"Employee benefits journal","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2013-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81795126","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Individuals continue to \"bunch\" at the convex kink the AET creates even when they are no longer subject to the AET, demonstrating that adjustment frictions help drive behavior in a new and important context. We develop a novel framework for estimating an earnings elasticity and an adjustment cost using information on the amount of bunching at kinks before and after policy changes in earnings incentives around the kinks. We apply this method in settings in which individuals face changes in the AET benefit reduction rate, and we estimate in a baseline case that the earnings elasticity with respect to the implicit net-of-tax share is 0.23, and the fixed cost of adjustment is $152.08.
