Estimating the perceived tax scale within a labor supply model
- 1996
-
Ingår i: Economics Letters. - : Elsevier BV. - 0165-1765 .- 1873-7374. ; 52:1, s. 75-79
-
Tidskriftsartikel (refereegranskat)abstract
- The Swedish marginal tax scale is too complex to be known in detail by individuals. This paper indicates that perceived tax scales can be estimated jointly with a labor supply equation. The differences between the true and estimated tax scales are found to be small.

Omitted variables in a weibull regression model
- 1984
-
Ingår i: Economics Letters. - : Elsevier BV. - 0165-1765 .- 1873-7374. ; 16:3-4, s. 279-283
-
Tidskriftsartikel (refereegranskat)abstract
- Asymptotic biases of maximum likelihood and least squares estimators in a Weibull model, subject to omitted variables, are given. The results are contrasted to those of a small sample Monte Carlo experiment.

Small sample properties in a heterogenous Weibull model
- 1986
-
Ingår i: Economics Letters. - : Elsevier BV. - 0165-1765 .- 1873-7374. ; 21:1, s. 17-20
-
Tidskriftsartikel (refereegranskat)abstract
- Neglected heterogeneity implies bias for estimators in, e.g., the Weibull duration model. In a Monte Carlo experiment the proper maximum likelihood estimator is better than a new least squares estimator. The likelihood estimator neglecting heterogeneity is inferior.

Hypothetical versus real payments in Vickrey auctions
- 1997
-
Ingår i: Economics Letters. - : Elsevier B.V. - 1873-7374 .- 0165-1765. ; 56:2, s. 177-180
-
Tidskriftsartikel (refereegranskat)abstract
- We compare hypothetical and real payments in a Vickrey auction. The use of hypothetical payments overestimates the real willingness to pay. The results cast doubt on the validity of hypothetical willingness to pay questions for the typical respondent.

On the power and interpretation of panel unit root tests
- 2000
-
Ingår i: Economics Letters. - : Elsevier. - 0165-1765 .- 1873-7374. ; 66:3, s. 249-255
-
Tidskriftsartikel (refereegranskat)abstract
- We demonstrate that panel unit root tests can have high power when a small fraction of the series is stationary and may lack power when a large fraction is stationary. The acceptance or rejection of the null is thus not sufficient evidence to conclude that all series have a unit root or that all are stationary.

Compensating wage differentials and shift work preferences : Evidence from France
- 2002
-
Ingår i: Economics Letters. - 0165-1765 .- 1873-7374. ; 74:3, s. 393-398
-
Tidskriftsartikel (refereegranskat)abstract
- We study if there are compensating wage differentials paid for shift work using French matched employer–employee data for male full-time blue collar workers. There is a significant shift premium of 16% that has a significant impact on shift work choice.

A flexible specification of adjustment costs in dynamic factor demand models
- 2001
-
Ingår i: Economics Letters. - : Elsevier. - 0165-1765 .- 1873-7374. ; 72:2, s. 144-150
-
Tidskriftsartikel (refereegranskat)abstract
- This paper proposes a flexible form of adjustment cost function. An empirical illustration shows that the flexible form can detect both convex and non-convex adjustment costs. Furthermore, the flexible form permits testing for the experience effect on adjustment cost.

Post mortem reputation, compensatory gifts and equal bequests
- 2000
-
Ingår i: Economics Letters. - 0165-1765 .- 1873-7374. ; 68:2, s. 165-171
-
Tidskriftsartikel (refereegranskat)abstract
- Suppose that gifts are private information, only known to donor and donee, while bequests are public. Also suppose that parents care about the reputation that their bequest behavior will give them and that reputation deteriorates with the difference in amounts inherited. Then the optimal choice of altruistic parents is compensatory gifts and equal bequests. This is also what data show.

Ownership and input prices : A comparison of public and private enterprises
- 1996
-
Ingår i: Economics Letters. - 0165-1765 .- 1873-7374. ; 53:1, s. 33-38
-
Tidskriftsartikel (refereegranskat)abstract
- I compare public and private enterprise performance using input prices. The data are from primary and secondary market purchases in Sweden of a homogeneous capital item - 800 garbage trucks. Private firms pay 10-15% less than public enterprises.
