Abstract [en]

This article introduces two different non-parametric wavelet-based panel unit-root tests in the presence of unknown structural breaks and cross-sectional dependencies in the data. These tests are compared with a previously suggested non-parametric wavelet test, the parameteric Im-Pesaran and Shin (IPS) test and a Wald type of test. The results from the Monte Carlo simulations clearly show that the new wavelet-ratio tests are superior to the traditional tests both in terms of size and power in panel unit-root tests because of its robustness to cross-section dependency and structural breaks. Based on an empirical Central American panel application, we can, in contrast to previous research (where bias due to structural breaks is simply disregarded), find strong, clear-cut support for purchasing power parity (PPP) in this developing region.

Abstract

Women constitute a clear minority in the field of information and communications technology (ICT) in higher education as well as in the job market. At the same time, this field is expected to have a shortage of qualified people in the future. Do women and men engineering graduates have the same career opportunities? This article problematizes the relationship between higher education in engineering and opportunities on the job market. The results show that men reach higher positions to a greater extent than women, and that women remain in low-qualification jobs to a greater extent than men.

Abstract [sv]

Kvinnor utgör en klar minoritet inom området informations- och kommunikationsteknologi, både inom den högre utbildningen och på arbetsmarknaden. Artikeln problematiserar relationen mellan den högre tekniska utbildningen och positioner på arbetsmarknaden. Får kvinnor och män samma utbyte av sin ingenjörsexamen i arbetslivet? Resultaten visar att män i större utsträckning än kvinnor når högre positioner. Vidare ser vi att kvinnor stannar i lågkvalificerade jobb i högre utsträckning än män.

Abstract [en]

A Swedish radon data set, consisting of more than 8000 measurements of residential radon levels in about 50% of the Swedish municipalities were analysed using a multilevel approach.

The results were compared with those of a single-level analysis. We found that there was a significant variability between municipalities. The point estimates of the population mean radon levels were similar (geometric mean 60 Bq/m3 and arithmetic mean 106 Bq/m3).

The analysis shows the advantages of multilevel modeling compared with a single-level OLS model.

A single-level model results in too optimistic standard errors, about 25% of those of the multilevel

model which can lead to erroneous conclusions.

In a multilevel model including house type as a fixed effect (single-family house, row house, or apartment in multi-family house), the estimates of the fixed effect of house type were similar for the single-level and the multi-level models

Abstract [en]

This paper describes an alternative approach for testing for the existence of trend among time series. The test method has been constructed using wavelet analysis which has the ability of decomposing a time series into low frequencies (trend) and high-frequency (noise) components. Under the normality assumption, the test is distributed as F. However, using generated empirical critical values, the properties of the test statistic have been investigated under different conditions and different types of wavelet. The Harr wavelet has shown to exhibit the highest power among the other wavelet types. The methodology here has been applied to real temperature data in Sweden for the period 1850-1999. The results indicate a significant increasing trend which agrees with the 'global warming' hypothesis during the last 100 years.
