Announcement effects of bank mergers in Europe and the US

We investigate the announcement effect of large bank mergers in the European and US stock market. Cumulative abnormal returns are calculated on the basis of the performance vis-à-vis the market and a sector index. Mergers result in small positive abnormal returns. Target banks realize significantly higher returns than bidders. In many respects, there is a difference between the announcement effects of European bank mergers compared to those in the US.     

On the Relationship Between Acquisitions, Divestitures and Innovations: An Explorative Study

Firms increasingly use acquisitions and divestitures to acquire strategic assets such as technological know-how and technological capabilities that can contribute to their innovation potential. This study investigates whether firms combining acquisitions and divestitures have been more innovative than those that did not. It uses an empirical model to examine the relationship between acquisitions and/or divestitures, on the one hand, and the probability of firms to produce innovations, on the other hand. Innovations are distinguished according to products and/or processes that are “new to the firm” as a proxy for all innovations including imitations and those that are “new to the market” which is a proxy for so-called real innovations, excluding imitations. In order to test the model a data set is used that includes 2381 firms and was derived from the Dutch Community Innovation Survey (CIS-2) survey for the years 1994–1996. The estimation results show that divestitures in the services industry affect the probability to innovate positively in case of innovations that are “new to the firm”. In the manufacturing industry, a stable and positive correlation was found between acquisitions and/or divestitures on the hand, and real innovation activities of firms on the other hand.     

Harlem—tourism market assessment and potential

With the growth of alternative and special interest tourism the New York Uptown Chamber of Commerce with local community and business groups have begun to explore ways in which tourism may contribute to the economy and vitality of Harlem. Bert Highet and Walter Johnson of Quadrant Marketing report here on their commissioned research into an assessment of the tourism potential of the area.

Site competence dynamics in international manufacturing networks: instrument development and a test in Eastern European factories

The objective of this paper is to introduce an instrument that enables the measurement of dynamics in the roles of factories in international networks. Starting from Ferdows’ framework on strategic factory roles, a clear definition and more precise operationalization of ‘site competence’ is provided. Our proposed instrument is tested in a context, being the Eastern European factories of Dutch multinationals, where it is plausible to expect changes in the strategic factory roles over time. This test comprises four exploratory case studies that provide the basis for future, more extensive empirical work. At the same time, they contribute to the under-researched area of company and industry case studies with respect to the international context of operations management.     

An econometric model of potential output, productivity growth, and resource utilization

This paper specifies a macroeconometric model providing a simultaneous framework for estimating the natural rate of unemployment, the full-employment (FE) labor force and hours of work, the FE productivity growth rate, and the growth path of potential (FE) output during 1960–2000. The estimated output and unemployment gaps are consistent with Okun’s Law. Historical perspective is provided on the expansion of the nineties by comparing it with those of the three previous decades in terms of growth and utilization of potential output. Factors accounting for the growth of potential output, productivity and labor supply are identified and compared.     

How Debt Creates Pressure to Perform when Information Asymmetries are Large: Empirical Evidence from Business Start‐ups

In this paper, we empirically examine how leverage affects firm performance when information asymmetries are large. We argue that entrepreneurs are strongly incentivized to maximize earnings when leverage is high in order to reduce the likelihood of adverse credit decisions and firm liquidation. Our empirical tests focus on the effects of leverage on firm profitability and growth in earnings during a 5‐year window after start‐up for a large and unique sample of newly established ventures in Belgium. Accounting for the endogeneity of leverage, the data reveal that more highly indebted business start‐ups are not only more profitable but also realize larger earnings growth. Moreover, the positive effect of leverage on firm profitability intensifies as the venture matures.     

The minimum weighted covariance determinant estimator

In this paper, we introduce weighted estimators of the location and dispersion of a multivariate data set with weights based on the ranks of the Mahalanobis distances. We discuss some properties of the estimators like the breakdown point, influence function and asymptotic variance. The outlier detection capacities of different weight functions are compared. A simulation study is given to investigate the finite-sample behavior of the estimators. The research of Stefan Van Aelst was supported by a grant of the Fund for Scientific Research-Flanders (FWO-Vlaanderen) and by IAP research network grant nr. P6/03 of the Belgian government (Belgian Science Policy).     

Coming to Terms with Accountability

Abstract

In this article, we develop a theoretical argument that leads to a more optimistic outlook on the present state of accountability. By combining the different forums and functions of accountability in a multidimensional manner, the possibilities to hold power to account may be larger than often assumed. The main reason is that functions no longer depend on the well-functioning of a single forum and each forum serves multiple functions. In order to study accountability on a more systematic basis, we urgently need a solid conceptual framework. We aim to contribute to this much wanted coming to terms with accountability.     

Analyzing fixed-event forecast revisions

It is common practice to evaluate fixed-event forecast revisions in macroeconomics by regressing current forecast revisions on one-period lagged forecast revisions. Under weak-form (forecast) efficiency, the correlation between the current and one-period lagged revisions should be zero. The empirical findings in the literature suggest that this null hypothesis of zero correlation is rejected frequently, and the correlation can be either positive (which is widely interpreted in the literature as “smoothing”) or negative (which is widely interpreted as “over-reacting”). We propose a methodology for interpreting such non-zero correlations in a straightforward and clear manner. Our approach is based on the assumption that numerical forecasts can be decomposed into both an econometric model and random expert intuition. We show that the interpretation of the sign of the correlation between the current and one-period lagged revisions depends on the process governing intuition, and the current and lagged correlations between intuition and news (or shocks to the numerical forecasts). It follows that the estimated non-zero correlation cannot be given a direct interpretation in terms of either smoothing or over-reaction.
