Long memory and changing persistence

We study the empirical behaviour of semi-parametric estimation for long-memory models when the true data generating process exhibits a change in persistence. Evidence for long memory is likely to be found. Procedures for discrimination between different models are proposed.     

Air accessibility and growth – The economic effects of a capacity expansion at Vienna International Airport

We use an econometric endogenous growth model to estimate the impact of air accessibility on GDP and investment growth. This is done in a dynamic panel system estimation framework for the EU-15 between 1993 and 2006. The results are then used to predict the economic effects of an increase in capacity at the Vienna International Airport using actual forecasts of the required information set. We find a GDP elasticity of air accessibility of 0.014 and an investment elasticity of 0.05 for our sample. Given the official passenger forecast this would lead to additional GDP growth in Austria of accumulated 0.81% based on the values of the restricted scenario (no third runway). In a more conservative forecast scenario of 3% annual passenger growth, a third runway is projected to increase GDP by 0.2% by 2040.     

Wertorientierte Steuerung von Lebensversicherungsunternehmen mittels stochastischer Prozesse

In this paper we present the concept for value based management of life insurance companies using stochastic process methods. The stochastic processes are used for modelling the random parameters determining the value. Stochastic processes in discrete and continuous time as well as with discrete and continuous state space are considered. As shown in the article this results in distribution functions for the corporate value which lie approximately or even exactly in the class of normal distribution functions.     

Necessity and Opportunity Entrepreneurs and Their Duration in Self-employment: Evidence from German Micro Data

Using data from the German Socio-Economic Panel Study (GSOEP), we analyze whether necessity entrepreneurs differ from opportunity entrepreneurs in terms of self-employment duration. Using univariate statistics, we find that opportunity entrepreneurs remain in self-employment longer than necessity entrepreneurs. However, after controlling for the entrepreneurs’ education in the professional area where they start their venture, this effect is no longer significant. We therefore conclude that the difference observed is not an original effect but rather is due to selection. We then go on to discuss the implications of our findings for entrepreneurship-policy making, and give suggestions to improve governmental start-up programs.

Entrepreneurial orientation in long-lived family firms

We apply a key construct from the entrepreneurship field, entrepreneurial orientation (EO), in the context of long-lived family firms. Our qualitative in-depth case studies show that a permanently high level of the five EO dimensions is not a necessary condition for long-term success, as traditional entrepreneurship and EO literature implicitly suggest. Rather, we claim that the level of EO is dynamically adapted over time and that the original EO scales (autonomy, innovativeness, risk taking, proactiveness, and competitive aggressiveness) do not sufficiently capture the full extent of entrepreneurial behaviors in long-lived family firms. Based on these considerations we suggest extending the existing EO scales to provide a more fine-grained depiction of firm-level corporate entrepreneurship in long-lived family firms.     

The Continuing Continuum Problem of Deposits and Loans

Barnett and Block (J Bus Ethics 18(2):179–194, 2011) argue that one cannot distinguish between deposits and loans due to the continuum problem of maturities and because future goods do not exist—both essential characteristics that distinguish deposit from loan contracts. In a similar way but leading to opposite conclusions (Cachanosky, forthcoming) maintains that both maturity mismatching and fractional reserve banking are ethically justified as these contracts are equivalent. We argue herein that the economic and legal differences between genuine deposit and loan contracts are clear. This implies different legal obligations for these contracts, a necessary step in assessing the ethics of both fractional reserve banking and maturity mismatching. While the former is economically, legally, and perhaps most importantly ethically problematic, there are no such troubles with the latter.
