Health Care System Effects on Cost Efficiency in the OECD Countries

Gerdtham, Ulf-G.; Löthgren, Mickael - Economics Institute for Research (SIR), … - 1998

This paper investigates the effects of different health systems on cost efficiency in inpatient health care among the OECD countries. The results indicate that public contract systems are less efficient and that public integrated health systems are more efficient than public reimbursement systems.

Maximum-likelihood based inference in the two-way random effects model with serially correlated time effects

Karlsson, Sune; Skoglund, Jimmy - Economics Institute for Research (SIR), … - 2000

This paper considers maximum likelihood estimation and inference in the two-way random effects model with serial correlation. We derive a straightforward maximum likelihood estimator when the time-specific component follow an AR(1) or MA(1) process. The estimator is easily generalized to...

Testing for common cointegrating rank in dynamic panels

Larsson, Rolf; Lyhagen, Johan - Economics Institute for Research (SIR), … - 2000

The panel cointegration test of Larsson et al (1998) test for the maximum number of cointegrating relations in a … dynamic panel given the assumption of a common cointegrating rank. This paper presents a test for this assumption. The test is … based on the test statistic of Larsson et al (1998) and a new panel test based on the principal component estimator of …

Specification and estimation of random effects models with serial correlation of general form

Skoglund, Jimmy; Karlsson, Sune - Economics Institute for Research (SIR), … - 2001

This paper is concerned with maximum likelihood based inference in random effects models with serial correlation. Allowing for individual effects we introduce serial correlation of general form in the time effects as well as the idiosyncratic errors. A straightforward maximum likelihood...

Bootstrapping Error Component Models

Andersson, Michael K.; Karlsson, Sune - Economics Institute for Research (SIR), … - 1999

This paper proposes several resampling algorithms suitable for error component models and evaluates them in the context of bootstrap testing. In short, all the algorithms work well and lead to tests with correct or close to correct size. There is thus little or no reason not to use the bootstrap...

Asymptotic properties of the maximum likelihood estimator of random effects models with serial correlation

Skoglund, Jimmy; Karlsson, Sune - Economics Institute for Research (SIR), … - 2001

This paper considers the large sample behavior of the maximum likelihood estimator of random effects models with serial correlation in the form of AR(1) for the idiosyncratic or time-specific error component. Consistent estimation and asymptotic normality as N and/or T grows large is established...
