Competition and Concentration in the New European Banking Landscape

This paper measures the degree of concentration and competition in the enlarged European Union (EU) banking environment over the period 1998–2002. In the empirical part we opt for a methodology as proposed by Panzar and Rosse based on a non‐structural estimation of market competition. Our results suggest that European banks were operating under conditions of monopolistic competition and that bank interest revenues in the 10 new EU member states was earned under conditions of higher competition than those that existed in the old EU banking countries. The opposite result was observed for total operating revenues. Smaller banks earn interest income in a less competitive environment than larger banks, while the opposite is observed for total revenues.     

The Analysis of Welfare Effects of an Environmental Product Tax: An Application to the Taxation of Car Tyres in Hungary

A sophisticated welfare analysis developed by Morris and Kis (1996) is presented here for the study of the effect of a product charge tax on the car tyre market in Hungary. The analysis is extended and complemented in this paper by, first, using the AIDS model and an algorithm developed by Galarraga and Markandya (2000) to estimate demand elasticities from limited data and, second, including the income effects into the analysis. The latter does not have much impact on the results but the generalisation of the model might be useful for the analysis of different goods where the proportion of income spent on them is more important.     

Rethinking Rouse and Daellenbach's rethinking: isolating vs. testing for sources of sustainable competitive advantage

In a recent paper, Rouse and Daellenbach (1999) provide a five‐step methodological approach which they feel will cure alleged inadequacies in empirical resource‐based research. We suggest, however, that their methodology can provide only a useful aid for expanding our understanding of potential sustainable competitive advantages but will not allow researchers to effectively verify those hypothesized advantages. Specifically, we argue that Rouse and Daellenbach's methodology is plagued by three major shortcomings: (1) it confuses the important distinction between knowing‐how and knowing‐what; (2) it fails to recognize the importance of observable variables in verifying the sources of sustainable competitive advantage; and (3) it calls for sampling on the dependent variable.

Valuation uncertainty,home and host market uncertainty,and cross-border seasoned equity offerings

This study examines how market timing can affect host market reaction to cross-border seasoned equity offerings (SEOs), an event generally viewed unfavorably by investors. We assume that firms engage in market timing in response to valuation uncertainty (VU), home market uncertainty (HMU) and/or host market uncertainty (HSU), and that raising capital abroad faces higher scrutiny costs and familiarity bias from host market investors. We conjecture that timing strategies provide signals that vary in strength to host market investors and that dual-timing strategies may strengthen an existing signal. Our hypotheses are tested on a sample of 190 cross-border SEOs that were issued on the U.S. stock market between 1990 and 2017 by firms from 29 countries. Using event study methodology, we find that market timing based on VU is negatively related to host market valuation and that a dual-timing strategy with HMU or HSU generally produces a stronger signal. Our results have practical relevance for stock markets that suffer from high uncertainty; we estimate that a high VU firm with a $1 billion valuation suffers a drop of $31.3 million in market valuation during a high host market uncertainty (high HSU) compared with low host market uncertainty (low HSU).     

Knowledge relatedness and the performance of multibusiness firms

This study examines corporate performance effects of cross‐business knowledge synergies in multibusiness firms. It synthesizes the resource‐based view of diversification and the economic theory of complementarities to conceptualize cross‐business knowledge synergies in terms of the relatedness and the complementarity of knowledge resources across business units of the multibusiness firm. The study hypothesizes that corporate performance is improved when the firm simultaneously exploits a complementary set of related knowledge resources across its business units. In a sample of 303 multibusiness firms, the study finds that synergies arising from product knowledge relatedness, customer knowledge relatedness, or managerial knowledge relatedness do not improve corporate performance on their own. Synergies arising from the complementarity of the three types of knowledge relatedness significantly improve both market‐based and accounting‐based performance of the multibusiness corporation.

Econometrics for Policy Analysis: Progress and Regress

Progress, regress, and continuity in quantitative analysis for policy are discussed. We look at the present from the perspective of Tinbergen, Haavelmo, and Keynes. Probability modeling has been in retreat at central banks and elsewhere. New computational methods, though, are making Bayesian analysis of previously intractable problems possible, and at the same time appreciation of the clarity with which Bayesian data analyis integrates with decison-making is spreading.
