A Typology of International New Ventures: Empirical Evidence from High‐Technology Industries

We examine determinants of different types of International New Ventures (INVs), namely Export Start‐up, Geographically Focused Start‐up, Multinational Trader, and Global Start‐up. Whereas this typology of INVs has been widely accepted in the literature, empirical testing of the determinants of INV types is largely missing. Our arguments build on the International New Venture Theory (INVT). Hypotheses generated from our framework are tested on 195 German high‐tech enterprises. Results show that growth orientation, prior international experience, knowledge intensity, product differentiation, and learning orientation distinguish significantly between the different INV types.

Central bank transparency and financial market expectations: The case of emerging markets

In this paper, we study how central bank transparency influences the formation of money market expectations in emerging markets. The sample covers 25 countries for the period from January 1998 to December 2009. We find, first, that transparency reduces the bias (the difference between the money market rate and the weighted expected target rate over the contract period) in money market expectations. The effect is larger for countries with no exchange rate peg and countries with low income. Second, an intermediate level of transparency is found to have the most favorable influence on money market expectations: neither complete secrecy nor complete transparency is optimal. Finally, all subcategories of the Eijffinger and Geraats (2006) index lead to a smaller bias in expectations, with political transparency having the largest effect.     

A new fluctuation test for constant variances with applications to finance

We present a test to determine whether variances of time series are constant over time. The test statistic is a suitably standardized maximum of cumulative first and second moments. We apply the test to time series of various assets and find that the test performs well in applications. Moreover, we propose a portfolio strategy based on our test which hedges against potential financial crises and show that it works in practice.     

Die Erwartungen der Wirtschaft für 2012

Nach einem wirtschaftlich sehr positiven Jahr 2011, mussten die ?konomischen Prognosen für das Wachstum 2012 deutlich herabgesetzt werden. Die Wirtschaftsforschungsinstitute erwarten für Deutschland nur noch ein Wachstum von 0,8%. Die Vertreter der einzelnen Industriezweige sind aber etwas optimistischer als die Prognosen für die Gesamtwirtschaft.     

Probability and quantile estimation from individually micro-aggregated data

Micro-aggregation is a frequently used strategy to anonymize data before they are released to the scientific public. A sample of a continuous random variable is individually micro-aggregated by first sorting and grouping the data into groups of equal size and then replacing the values of the variable in each group by their group mean. In a similar way, data with more than one variable can be anonymized by individual micro-aggregation. Data thus distorted may still be used for statistical analysis. We show that if probabilities and quantiles are estimated in the usual way by computing relative frequencies and sample quantiles, respectively, these estimates are consistent and asymptotically normal under mild conditions.
