The aim of these lecture notes is to give a quick introduction into neural networks, its algorithms and applications. The notes are not intended as a replacement of a comprehensive textbook.
Die vorliegende Diplomarbeit untersucht die Möglichkeiten, durch Mediation Konflikte bei Geschäftsverhandlungen zwischen unterschiedlichen Ländern und Kulturen zu schlichten.
Based on data from a recent representative survey of the adult population in Germany this paper documents that the patterns of variables influencing nascent and infant entrepreneurship are quite similar and broadly in line with our theoretical priors – both types of entrepreneurship are fostered by the width of experience and a role model in the family, and hindered by risk aversion, while being male is a supporting factor. Results of this study using cross section data are in line with conclusions from longitudinal studies for other countries finding that between one in two and one in three nascent entrepreneurs become infant entrepreneurs, and that observed individual characteristics – with the important exception of former experience as an employee in the industry of the new venture - tend to play a minor role only in differentiating who starts and who gives up.
This paper studies the empirical effect of risk classification in the mandatory third-party motor insurance (TPMI) of Germany. We find evidence that inefficient risk categories had been selected in this market while potentially efficient information may have been dismissed. Risk classification did generally not improve the efficiency of contracting or the composition of insureds in this market. These findings can be partly explained by the existence of compulsory fixed coverage and other institutional restraints such as unitary owner insurance in this market.
This paper analyzes, within a regional growth model, the impact of productive governmental policy and integration on the spatial distribution of economic activity. Integration is understood as enhancing territorial cooperation between the regions, and it describes the extent to which one region may benefit from the other region’s public input, e.g. the extent to which regional road networks are connected. Both integration and the characteristics of the public input crucially affect whether agglomeration arises and if so to which extent economic activity is concentrated: As a consequence of enhanced integration, agglomeration is less likely to arise and concentration will be lower. Relative congestion reinforces agglomeration, thereby increasing equilibrium concentration. Due to the congestion externalities, the market outcome ends up in suboptimally high concentration.
This paper examines whether the labor market prospects of Arab men in England are influenced by recent Islamistic terrorist attacks and the war on Iraq. We use data from the British Labour Force Survey from Spring 2001 to Winter 2006 and treat the terrorist attacks on the USA on September 11th, 2001, the Madrid train bombings on March 11th, 2004 and the London bombings on July 7th, 2005, as well as the beginning of the war on Iraq on March 20th, 2003, as natural experiments possibly having led to a change in attitudes toward Arab or Muslim men. Using treatment group definitions based on ethnicity, country of birth, current nationality, and religion, evidence from regression-adjusted di_erence-in-di_erences-estimators indicates that the real wages, hours worked and employment probabilities of Arab men were unchanged by the attacks. This finding is in line with prior evidence from Europe.
