By using the quantile regressions of earnings equation, we find that the educational wage premium is higher in industries with rapid technological change than in industries with slower technological change at every decile in the distribution of wage residuals. The wage premium associated with...

The Breusch--Godfrey LM test is one of the most popular tests for autocorrelation. However, it has been shown that the LM test may be erroneous when there exist heteroskedastic errors in a regression model. Recently, remedies have been proposed by Godfrey and Tremayne [9] and Shim <italic>et al.</italic> [21]....

This note re-estimates our model of the determinants and impacts of cost component incentive regulation using an improved data set which avoids double-counting firm observations. It also tests alternative specifications of the relationships. While cost component incentive regulation improves...

The Breusch-Godfrey’s LM test is one of the most popular tests for autocorrelation. However, it has been shown that the LM test may be erroneous when there exist heteroskedastic errors in regression model. Some remedies recently have been proposed by Godfrey and Tremayne (2005) and Shim et al....

Conventional tests for rationality of survey data on expectations are not valid in the presence of measurement errors. However, if two or more survey measures of expectations are available on the true unobserved expectational variables, we can devise the appropriate FIML estimation methods and...

This paper investigates the potential problem of ‘pseudo-exogenous’ instruments in regression models. We show that the performance of Hausman test is deteriorated when the instruments are asymptotically exogenous but endogenous in finite samples, through Monte Carlo simulations.

An econometric model is presented to compare the cost-effectiveness of two alternative procedures, percutaneous transluminal coronary angioplasty (PTCA) and coronary artery bypass surgery (CABG), for the treatment of multivessel coronary artery disease. This study utilizes the MIMIC (multiple...

This empirical study examines the determinants and impacts of incentive regulations introduced by utility commissions in the late 1970s and early 1980s. Rewards for generating plant utilization and low heat rates were found to have been introduced in states whose firms exhibited relatively high...
