This paper is a first attempt to estimate the size and development of the shadow economy of 158 countries over the period 1991 up to 2015. Using the Multiple Indicators, Multiple Causes (MIMIC) method we apply for the first time (i) the light intensity approach instead of GDP avoiding the...

Accessibility of real-time data is crucial for applied macroeconomic researchers who aim at evaluating forecasts, policy decisions or the accuracy of initial data estimates. To the extent of our knowledge, no appropriate and comprehensive real-time data set has been published for Switzerland so...

The next tool for social science experimentation should allow for macro level, generalizable, scientific research. In the past devices such as rat mazes, Petri dishes and supercolliders have been developed when scientists needed new tools to do research. We believe that Virtual Worlds are the...

We present an approach for estimating time series of a set of latent variables satisfying accounting identities. We concentrate on a simple case study and comment on possible generalizations. The model consists of three main parts: (i) A system of accounting identities, e.g., a subsystem of the...

Aggregation of tangible capital assets across vintages and decomposition of value aggregates into quantities and prices are considered. Focus is on both capital stock values and capital service values. If the definitions and ways of measuring prices and quantities are not conformable, a third...

In the present globalization era an increasing attention is paid to the ambiguous relationship between international migration, brain drain, and economic growth, but few papers analyzed the growth impact of skilled migration. The paper filled the research gap by building the first dataset on...

Based on the hypothesis that microdata are of crucial importance for internationally competitive economic research and scientific advice in economic and social policy, the authors develop various proposals for an improved data supply for empirical work in Germany. Present shortcomings are mainly...

This paper proposes a new method of forecasting euro area quarterly real GDP that uses area-wide indicators, which are derived by optimally pooling the information contained in national indicator series. Following the ideas of predictive modeling, we construct the area-wide indicators by...
