The demand for medical care services: evidence from Kuwait based on households’ out-of-pocket expenses

This article used a data set containing information on 1267 households from Kuwait to investigate the determinants of demand for medical care services by examining households’ out-of-pocket expenses. To deal with the problems associated with households’ health expenditure data, a two-part model (TPM) was estimated. Given Kuwait’s demographic composition, the model was estimated for full sample, nationals only and expatriates only. Prior to estimating the model, tests were conducted to select a transformation that reduces problems associated with heteroscedasticity and non-normality of the errors. In addition, tests were performed to determine if differences in the estimated coefficients across population groups were statistically significant.     

Do non-profit hospitals provide more charity care when faced with a mandatory minimum standard? Evidence from Texas

Policymakers often question whether not-for-profit (NFP) hospitals provide enough charity care to justify tax advantages. In 1993, Texas enacted legislation requiring NFP hospitals to provide certain community benefits at levels set forth in specific criteria to retain tax-exempt status; this paper focuses on the effect of the legislation’s requirement that NFP hospitals spend a minimum of 4% of net patient revenue on charity care. We also study a modification of the law passed in 1995, which allows the deduction of bad debts expense when calculating net patient revenue. This change effectively lowers required charity care spending, and our study considers whether Texas hospitals responded by reducing charity care spending.     

Wagner's hypothesis: evidence from Kuwait using cointegration tests

This paper investigates the relationship between public expenditure and a number of socioeconomic variables, including the level of income, in Kuwait. A general form of the public expenditure function is formulated and recent developments in time series econometrics, including unit roots and cointegration tests, and an error-correction model are used. Given the characteristics of the economy, alternative measures for each variables are used. The analysis in the paper is based on time-series data covering the period from 1969/70 to 1994/95. In general, the findings lend little support to the existence of long-run equilibrium relationship between public expenditure and the socioeconomic variables, and the evidence does not lend support to the validity of Wagner's law in Kuwait.     

A path model examining the relations among strategic performance measurement system characteristics,organizational justice,and extra- and in-role performance

Economic theory suggests that multiple financial and non-financial measures (i.e., a strategic performance measurement system “SPMS”) be used in compensation contracting to properly direct employees’ attention and motivate behavior aligned with organizational goals. Conversely, linking incentives to the SPMS can result in various dysfunctional behaviors, including game playing by employees, the achievement of unbalanced performance, and the potential of basing compensation on an incomplete performance measurement system. Prior literature has investigated the use of subjectivity in compensation contracting as a means of potentially mitigating these problems; however, subjectivity can introduce other problems including claims of favoritism and bias. Economic theorists have recently begun expanding the traditional agency model to include the notion of fairness or justice. In this study, we obtain data from an organization that uses an SPMS as the basis for the allocation of bonuses and investigate whether characteristics of the SPMS are associated with perceived organizational fairness. Specifically, we hypothesize and show that the extent to which employees perceive that the SPMS reflects a strategic causal model and the degree to which it is technically valid are positively associated with their perceptions of organizational justice. We also provide evidence that heightened levels of organizational justice are the mechanism though which the perceived characteristics of the SPMS are associated with employee performance. The implication is that firms do not necessarily need to introduce subjectivity into the incentive contracting system, but can enhance performance by linking incentive contracts to their SPMS if the system contains characteristics that enhance employees’ perceptions of justice.     

Valuation of Callable Warrants

A simple valuation model for callable warrants is derived and tested. The model is expressed in closed form except for one term which can be evaluated numerically. Predictions of 78 warrant prices are compared to market prices and the average error is -.224 percent. By contrast, the Black-Scholes model applied to the same warrants produces an average error of 31.44 percent. Thus the callability feature cannot safely be ignored in determining warrant values.     

KFAS mechanism of funding research and development: an assessment

This paper assesses mechanisms of funding research projects used by the Kuwait Foundation for the Advancement of Sciences (KFAS). KFAS is a leading organization that sponsors research projects in Kuwait and whose endowments come through contributions from private sector companies. The assessment described in the paper relies on time series data covering the period from 1978 to 1996. The analysis shows that KFAS funding of research projects has favored projects in sectors such as agriculture and food resources, and has assigned low priority to prime sectors, such as oil, water, and manufacturing. This reflects a lack of coherence between the organization's R&D activities and the country's socioeconomic plans and needs.
