Open source software (OSS) is marked by free access to the software and its source code. OSS is developed by a ‘community’ consisting of thousands of contributors from all over the world. Some research was undertaken in order to analyze how global the OSS community actually is, i.e. analyze the geographic origin of OSS developers. But as members of the OSS community differ in their activity lev...

The re-analysis of statistical data is an effective means of protecting the public from undiscovered errors in social science research. Re-analysis is critical, as there is no difference between official data and non-official data. However, discussions concerning data protection legislation do not usually take this into consideration. Proper data protection rules must make it possible to conduc...

In this paper, we employ stochastic dominance analysis on Australian unit records to investigate trends in inequality and relative welfare levels in Australia over the period 1983 to 2004. We find that that when the stochastic dominance tests are applied to income and expenditure distributions for the entire population, net transfers to households do not appear to make any significant differenc...

Experimental Tests of Survey Responses to Expenditure Questions This paper tests for a number of survey effects in the elicitation of expenditure items. In particular we examine the extent to which individuals use features of the expenditure question to construct their answers. We test whether respondents interpret question wording as researchers intend and examine the extent to which prompts, ...

The degree of mobility in incomes is often seen as an important measure of the equality of opportunity in a society and of the flexibility and freedom of its labor market. However, estimation of mobility using panel data is biased by the presence of measurement error and non-random attrition from the panel. This paper shows that dynamic pseudo-panel methods can be used to consistently estimate ...

Other-Regarding Preferences and Performance Pay – An Experiment on Incentives and Sorting Variable pay not only creates a link between pay and performance but may also help firms in attracting the more productive employees (Lazear 1986, 2000). However, due to lack of natural data, empirical analyses of the relative importance of the selection and incentive effects of pay schemes are so far thin...

Counterfactual decomposition allows the researcher to analyze the changes in wage distributions by discriminating between the e¤ect of changes in the population characteristics and the e¤ect of changes in returns to these characteristics. In this paper we propose to apply this methodology by recovering the conditional distribution via a set of quantile regressions. Additionally, we also propose...

Researchers often use unit values (household expenditures on a commodity divided by the quantity purchased) as proxies for market prices when calculating poverty lines and estimating consumer demand equations. Such proxies are often needed because community price surveys in developing countries are either absent or suffer quality problems. However, biases may result from using unit values, due ...

Celland receptor-specific regulation of cell migration by Gi/oa-proteins remains unknown in prostate cancer cells. In the present study, oxytocin (OXT) receptor was detected at the protein level in total cell lysates from C81 (an androgen-independent subline of LNCaP), DU145 and PC3 prostate cancer cells, but not in immortalized normal prostate luminal epithelial cells (RWPE1), and OXT-induced ...
