The implications of job matching for retirement health insurance and leave benefits

This paper focuses on potential reasons for variations in benefit packages, in particular variations in the availability of retirement health insurance and leave. An important feature of our analysis is that we do not start with heterogeneity in workforces to explain fringe benefit differences across employers. It would be straightforward to say that differences across employers in fringe benefit packages simply represent differences in the preferences of their workforces. Rather, we focus on heterogeneity across employers as an important source of differences in fringe benefit packages. Preliminary evidence is found supportive of the predicted differences in the likelihood of such fringe benefits as retirement health insurance and leave based upon two variables–the extent of on-the-job training offered by the employer and the size of the employers. We also examine the implied links between these fringe benefits and such variables as average tenture and the proportion of the workforce that is female.     

Quantity,quality and the welfare effects of US airline deregulation

In this paper we employ a method for estimationg quality-adjusted demand to calculate measures of the change in consumer suruplus due to US airline deregulation. The quality-adjusted estimates of the price elasticity of demand indicate that consumers are from 25% to 50% more sensitive to changes in air fares than unadjusted estimates would suggest. Changes in unadjusted consumer surplus overstate the net welfare gains from deregulation by roughly a factor of two, strongly suggesting that adjustments for quallity of service are essential to welfare analysis of regulatory changes in this industry     

Are auction revenues affected by rising art buyers’ premia? The case of early American art

The steady rise in the premiums charged to art buyers at auction (above hammer price) has been underway since 1992. This article, using a stable and bounded sample of repeat purchase of American works created before 1950, reveals that this tact has reduced hammer prices for that art. However, renewed and hyper-competitive efforts to bring more and higher quality art to market by the two main houses, Sotheby’s and Christie’s, have resulted in general profitability. Nevertheless, we calculate that a rise in buyers’ premia at Sotheby’s, a publically traded company, has reduced revenues and profits below their potential in the absence of such increases.     

Panel estimates of the earnings gap in Norway: do female immigrants experience a double earnings penalty?

This study explores the possibility that being both a ‘female’ and an ‘immigrant’ will impose an earnings disadvantage on immigrant women in Norway. Well-known techniques are used to decompose the earnings gap between Norwegian men and immigrant women into portions attributable to productivity differentials, portions attributable to a gender effect, and portions attributable to an ethnic effect. The analysis supports the following conclusions: First, there is evidence of a double negative effect on female immigrant earnings. Second, gender effect is more important than ethnic effect. Finally, the discrimination estimates are robust to the alternative methods used in decomposing Norwegian men-immigrant women earnings gap.     

Language training,language proficiency and earnings of immigrants in Norway

This paper uses a simple probit model to determine the impact of language training on the language proficiency of Third World immigrant men in Norway. It also estimates the labour market returns to Norwegian language proficiency. The results show that immigrants who participate in language training programme are more likely to acquire speaking and reading proficiencies in Norwegian language than those who do not. Contrary to expectation, language proficiency has no significant effect on immigrants' earnings. A probable explanation may be that immigrants need Norwegian language proficiency to get into jobs in the Norwegian labour market. Once they are in employment, their wages are not necessarily determined by their proficiency in Norwegian. Consistent with the assimilation hypothesis, earlier waves of immigrants have higher earnings than do more recent waves, and part of the initial earnings deficit experienced by more recent immigrants can be attributed to language deficiency. There was no evidence of sample selection bias in the earnings equation.     

Smokeless tobacco,smoking cessation and harm reduction: an economic analysis

Good estimates place ‘hard core’ smoking rates in the United States at approximately 25%, with little change over the decade of the 1990s. This paper examines the possibilities of ‘harm reduction’ with the use of smokeless tobacco. Specifically, using an econometric model we seek to determine whether an increase in the use of smokeless tobacco would lead to reduced smoking rates in the United States. Applying our model to the NHANES III (National Health and Nutrition Examination Survey) we find that the use of smokeless tobacco by an average U.S. male smoker would increase the average probability of smoke cessation by over 10%. Approximately 3 million additional ‘quits’ would result for 26 million smokers. Our study permits an examination of cessation by age groups and we find that males who use smokeless tobacco between 16 and 65 have a 10–14% probability of quitting but that the probability falls beyond age 66. Important implications for life extension and health costs would attend these results with, under conservative assumptions, life years saved approximating 2.16 million and health care cost-savings of about $3 billion per year.
