A new approach to optimal selection of services in health care organizations.

A new reimbursement policy adopted by Medicare in 1983 caused financial difficulties for many hospitals and health care organizations. Several organizations responded to these difficulties by developing systems to carefully measure their costs of providing services. The purpose of such systems was to provide relevant information about the profitability of hospital services. This paper presents a new method of making hospital service selection decisions: it is based on an optimization model that avoids arbitrary cost allocations as a basis for computing the costs of offering a given service. The new method provides more reliable information about which services are profitable or unprofitable, and it provides an accurate measure of the degree to which a service is profitable or unprofitable. The new method also provides useful information about the sensitivity of the optimal decision to changes in costs and revenues. Specialized algorithms for the optimization model lead to very efficient implementation of the method, even for the largest health care organizations.     

The Band Pass Filter*

We develop optimal finite‐sample approximations for the band pass filter. These approximations include one‐sided filters that can be used in real time. Optimal approximations depend upon the details of the time series representation that generates the data. Fortunately, for U.S. macroeconomic data, getting the details exactly right is not crucial. A simple approach, based on the generally false assumption that the data are generated by a random walk, is nearly optimal. We use the tools discussed here to document a new fact: There has been a significant shift in the money–inflation relationship before and after 1960.

Why is bank debt senior? A theory of asymmetry and claim priority based on influence costs

This theory can explain why bank debt is universally senior,consistent with the presence of conflict (lawyers) and absolutepriority violations in financial distress: Better organizedbanks would more strongly contest priority in financial distressif they were junior. Because 'deterrence' can reduce creditors'total expenses in a priority contest, the ex post stronger lobbyist/litigantshould be senior ex ante. For equivalent reasons, the theorycan advise when public debt should be senior to trade creditand/or implicit contrasts, and can even suggest one rationalefor the absolute priority rule (APR). This article further showsthat Chapter 11 creditor reimbursement procedures can loweroverall costs.     

Assessing the international spillover effects of capital income taxation

Changes in capital taxes by one economy spill onto other economies with internationally mobile capital. We evaluate these impacts using a two-region, intertemporal general equilibrium model. The foreign economy's unilateral reduction in corporate income taxation has positive but small effects on U.S. welfare. In contrast, unilateral reductions in personal income taxation impose large negative spillovers. The differences result from CIT being source-based and PIT residence-based. The CIT cut reduces tax burdens to U.S. residents who invest abroad, while the PIT cut reduces foreigners' tax burdens only. Through general equilibrium adjustments neglected in simpler models, the PIT cut lowers U.S. residents' welfare.     

Federal capital expenditures and budget deficits: Gross national product and labor implications

The issue of separating capital from operating expenditures has been largely ignored in discussions of the U.S. Federal Government's deficit. This paper attempts to overcome this void by conducting a simulation experiment designed to assess the macroeconomic consequences of separating capital from current expenditures under several alternative balanced budget rules and financing arrangements. The alternatives considered are directly related to management accounting issues and thus the purpose of this paper can be seen as compatible with the literature on the relationship between accounting techniques and economic analyses. The results of the study reaffirm the need for federal capital investment planning.     

Higher skilled working tourists and their leisure lifestyles: a qualitative study of guest language instructors in South Korea

Using interviews conducted with 24 higher skilled working tourists employed as guest language instructors in the Republic of Korea, this paper explores how working tourists could secure an optimal leisure lifestyle in their host countries. Three key findings emerged. First, the respondents were seeking casual, touristic, amateur, hobby and volunteer leisure with their colleagues and with their host community members. But, the rewards and episodic aspects of their leisure, including formal and informal language development, suggested that it incorporated variations in project-based leisure as a core characteristic. Second, these respondents were taking part in guest, host and leisure speech communities that were each offering leisure choices. However, their leisure lifestyle was best when leisure, second language development and acculturation coincided in a leisure speech community. Third, that in a leisure speech community, respondents’ acculturation and friendships improved more so than in either guest or host speech communities. Also, that these respondents’ formal and informal second language learning within their leisure speech communities was essential for an optimal leisure lifestyle. The paper determines that leisure speech communities, occurring along a continuum of monetary, educational and interpersonal resources, could affect the linguistic mobility of higher skilled working tourists. It recommends that future research could examine if a sociolinguistics of leisure could assist in exploring and mapping the leisure lifestyles appearing among mobile populations in a globalising world.
