This paper makes a theoretical contribution by investigating how the optimal copyright legislation depend on hidden information. A mixed hidden action – hidden information model is used. The regulator neither observes the type of firm nor the quality choice of firms. The paper provides no...

This paper studies intergenerational mobility among three generations of male immigrants in Sweden. We find a regression towards the native mean in earnings between immigrants and natives across the first two generations and a divergence in earnings between immigrants and natives across the...

This paper presents a model where workers’beliefs and expectations about discrimination are significant. Identical firms announce vacancies and starting wages and workers apply to the firm. Workers are of two types, b and g, but identical in productivity. Firms do not prefer a particular type...

This paper introduces and describes an alternative clustering approach based on the discrete wavelet transform (DWT) which satisfies requirements that other clustering methods, like discriminative-based clustering and model-based clustering approaches, do not satisfy. The clustering method has...

The aim of this study is to investigate the effect of privatisation on productivity development in the Chilean potable water and sewage sector. We have access to high quality firm level data making it possible to study the effects on a firm level. Productivity development is studied by means of...

This paper studies how group a±liation and intergroup bias may affect economic decision- making. Two types of experimental groupings are created and subjects are then paired with either an in-group member or an out-group member in a number of two-person games. The result of this experiment...

In this paper Markov Chain Monte Carlo algorithms(MCMC) are developed to facilitate the Bayesian analysis on nested designs when the error structure can be expressed as an autoregressive process of order one. Simulated and real data are also presented to confirm the efficiency and high accuracy...

This paper examines the supernatural punishment theory. The theory postulates that religion increases cooperation because religious people fear the retributions that may follow if they do not follow the rules and norms provided by the religion. We report results for a public goods experiment...

The main objective of this paper is to analyse the major transformations of the Swedish model. We argue that the current Swedish model appears today more in line with the three core components of the original Swedish model developed during the 1950s. In our view, the period 1975-1991 represents...

This paper describes a new approach to analys the Fractional Difference (FD) processes using spectral analysis. The approach is based on the periodogram and the main idea behind it is to divide the Fourier frequencies into different frequency intervals or bands, matching the band-pass of the...
