Motivated by weak small-sample performance of the censored regression quantile estimator proposed by Powell (1986a), two- and three-step estimation methods were introduced for estimation of the censored regression model under conditional quantile restriction. While those stepwise estimators have...

Traditionally, econometric research on social interaction effects has used fairly large social groups (schools, Census tracts, etc.). However, new data which describes the behavior of much smaller peer groups is becoming available. This paper analyzes the behavior of "small neighborhoods" in the...

Randomized experiments provide policy relevant treatment effects if there are no spillovers between participants and nonparticipants. We show that this assumption is violated for a Danish activation program for unemployed workers. Using a difference-in-difference model we show that the...

Structural Vector Autoregressions with a differenced specification of hours (DSVAR) suggest that productivity shocks identified using long--run restrictions lead to a persistent and significant decline in hours worked. This evidence calls into question standard business cycle models in which a...

Small firms often do not change their number of employees from year to year. This paper investigates the role of adjustment costs and indivisibility of labor in the employment stickiness of manufacturing firms with less than 75 employees. When small firms have to adjust employment in units of at...

In this paper I determine the importance of adjustment costs in employers hiring decisions. Temporary work arrangements offer potential ways to avoid adjustment costs. I estimate employers willingness to pay for the characteristics of these work arrangements. I distinguish regular contracts,...

In this paper we compare the new satisfaction evaluation approach, developed inthe nineties by Oswald ,Clark , Blanchflower and others with the older incomeevaluation (IEQ) approach, developed by Van Praag and Kapteyn in theseventies of the previous century. We find that both approaches yield...

Harmful algal bIoom species are the cause of important damages to marine living resources and human beings. These marine species are primarily introduced in North-European waters through ballast water, i.e. water trans-ported across the oceans so as to keep a vessel in balance. Port authorities...
