Robust Mean-Variance Portfolio Selection
This paper investigates model risk issues in the context of mean-variance portfolio selection. We analytically and numerically show that, under model misspecification, the use of statistically robust estimates instead of the widely used classical sample mean and covariance is highly beneficial for the stability properties of the mean-variance optimal portfolios. Moreover, we perform...

Tax Policy, Venture Capital, and Entrepreneurship
The paper studies the effects of tax policy on venture capital activity. Entrepreneurs pursue a single high risk project each but have no own resources. Financiers provide funds, covering investment cost plus an upfront payment, in exchange for a share in the firm. The contract must include incentives to enlist full effort of entrepreneurs. Venture capitalists also assist with...

Taxes and Venture Capital Support
In this paper we set up a model of start-up finance under double moral hazard. Entrepreneurs lack own resources and business experience to develop their ideas. Venture capitalists can provide start-up finance and commercial support. The effort put forth by either agent contributes to the firm's success, but is not verifiable. As a result, the market equilibrium is biased towards...

Mikroökonometrische Evaluation arbeitsmarktpolitischer Massnahmen
Viele europäische Länder verwenden neben einer passiven Einkommensabsicherung der Arbeitslosen die aktive Arbeitsmarktpolitik, um deren Wiederbeschäftigung zu beschleunigen. Zunehmend setzt sich dabei die Erkenntnis durch, dass diese kostenintensive Politik dem Steuerzahler nur bei nachweisbarem Nutzen langfristig zu vermitteln ist. Auch wenn die Bereitstellung der für seriöse...

The Effect of Disability on Labour Market Outcomes in Germany: Evidence from Matching
If labour market policies aimed at people with disabilities are effective, we should observe no significant difference in labour market outcomes between disabled and non-disabled individuals. This Paper examines the impact of disability status on labour market outcomes using matching methods associated with treatment effect techniques for programme evaluation. Such techniques are...

Tactical Asset Allocation mit genetischen Algorithmen
In this study of tactical asset allocation, we use a genetic algorithm to implement a market timing strategy. The algorithm makes a daily decision whether to invest in the market index or in a riskless asset. The market index is represented by the S&P500 Composite Index, the riskless asset by a 3-month T-Bill. The decision of the genetic algorithm is based on fundamental...

Inflation Forecast Uncertainty
We study the inflation uncertainty reported by individual forecasters in the Survey of Professional Forecasters 1969-2001. Three popular measures of uncertainty built from survey data are analyzed in the context of models for forecasting and asset pricing, and improved estimation methods are suggested. Popular time series models are evaluated for their ability to reproduce survey...

Asset Pricing in Macroeconomic Models
Analysis of financial prices in macroeconomic models rests on two building blocks: the consumption-based asset pricing model and the structure of payoffs. This chapter studies how different modelling choices affect yield curves (real and nominal), risk premia on equity (levered or not), and options. The emphasis is on surveying existing models and to bring out the basic mechanisms...

The Deterrent Effect of National Anti-Cartel Laws: Evidence from the International Vitamins Cartel
During the 1990s the European Commission and the United States Department of Justice between them prosecuted over 40 cartels that involved private firms and whose effects went beyond national borders. These private international cartels were found in a wide range of products - from citric acid, vitamins, newsprint, and fax paper to shipping and chemicals such as aluminium phosphide...

Can Developing Countries Benefit from Negotiations on Transparency in Government Procurement in the Doha Round?
It is important to appreciate how large the world's government procurement markets are. Although precise estimates are hard to come by, a recent analysis by the Organisation for Economic Co-operation and Development (OECD) indicates that total central government expenditures of its members, excluding military spending and the compensation of state employees, was just under $2...

Links between development and competition law in developing countries
The econometric literature on the effects of competition law on investment focuses almost exclusively on the consequences for inflows of foreign direct investment. What is more, the empirical papers in this literature can be counted on the figures of one hand and contain potentially contradictory findings. Precious little has been made of the potential effects of competition law...
