Dieser Beitrag hat zwei Ziele: Erstens werden die empirischen Ergebnisse über die Erlöse (Geldwäsche-Ströme) der transnationalen organisierten Kriminalität (TOK) weltweit sowie für einige OECD-Länder dargestellt sowie deren Größenordnung nach verschiedenen Verbrechensarten. Weiters...

Regression trees are evaluated with respect to mean square error (MSE), mean integrated square error (MISE), and integrated squared error (ISE), as the size of the training sample goes to infinity. The asymptotically MSE- and MISE minimizing (locally adaptive) regression trees are characterized....

Linear fractional stable motion is a type of a stochastic integral driven by symmetric alpha-stable L´evy motion. The integral could be considered as a non-Gaussian analogue of the fractional Brownian motion. The present paper discusses R package rlfsm created for numerical procedures with the...

In this study new realized volatility measures based on Multi-Scale regression and Discrete Sine Transform (DST) approaches are presented. We show that Multi-Scales estimators similar to that recently proposed by Zhang (2004) can be constructed within a simple regression based approach by...

The empirical evidence on the existence of social preferences-or lack thereof-is predominantly based on student samples. Yet, knowledge about whether these findings can be extended to the general population is still scarce. In this paper, we compare the distribution of social preferences in a...

The question of whether trade agreements are 'stepping stones' or 'stumbling blocks' to multilateral trade liberalization is not a new one; however, the empirical methods and the quality of the data used to address this question are continually improving. This paper explores this familiar...

We assess the forecast ability of Norges Bank's regional survey for inflation, GDP growth and the unemployment rate in Norway. We propose several factor models based on regional and sectoral information given by the survey. The analysis identifies which information extracted from the ten sectors...

We look at the link between the volatility in the Bitcoin market and the volatility in other related traditional markets, i.e. the gold, currency and stock market. We also try to answer if the volatility in the Bitcoin market can be explained by retail investor-driven internet search volumes or,...
