A general method is described which allows a production activity to be analyzed by means of input data only. According to duality theory, the input cost shares can be completely specified without any information about output if the technology is homothetic. It is demonstrated that these cost...

The scope of public human resource policy is outlined. Motivation for the need of transparency in this policy is provided in terms of informational asymmetries, human capital externalities, and long planning horizons. Transparency is defined both along a time dimension – ex ante and ex post...

In this paper a timesaving method is proposed for maximizing likelihood functions when the parameter space is subject to nonlinear constraints, expressible as second order polynomials. The suggested approach is especially attractive when dealing with systems with many parameters.

Most econometric multi-equation models estimated are assumed to be linear in both the variables and the parameters. One reason is that, in general, methods of linear algebra cannot be applied to nonlinear systems. <p> In this paper a certain class of nonlinear models is defined, however, the...</p>

Using a Difference-in-Differences approach, we evaluate the effects of a 10 percentage point reduction in the payroll tax introduced in 2002 in northern Sweden. We find no employment effects among firms existing both before and after the reform, whereas the average wage bill per employee...

Using a Difference-in-Differences approach we evaluate the effects of a 10 percentage points reduction in the payroll tax introduced in 2002 for firms in the northern part of Sweden. We find no employment effects for existing firms and can rule out that a 1 percentage point payroll tax reduction...

In Europe, accounting standards prevent larger expenditures on employer-sponsored training from being treated as investments. Using Sweden as example, we discuss two consequences for training. <p> First, the timing: training will be conducted when income is large enough for training costs to be...</p>

Investigating the robustness of the skill-biased technical change hypothesis, this analysis incorporates two novel features. First, effective labor is modeled as the product of a quantity measure - number of employees with a given level of education - and a quality index, depending on, i.a.,...
