Persistent misalignments of the European exchange rates: some evidence from non-linear cointegration

The asymmetric and persistent adjustment of the European real exchange rates is investigated using the framework of non-linear cointegration. The episodes of slow mean-reversion dynamics over the period from 1979 to 1999 are explained. A test of unit root against STAR cointegration is proposed and some complete estimations and stochastic simulations of ESTAR models are presented. The presence of effective non-linear adjustment during the moving of the currencies to their long-run fundamental equilibrium exchange rate value is discussed.     

Product diversification and stability of employment and sales: first evidence from German manufacturing firms

In this study, we use a unique rich newly built data set for German manufacturing enterprises to investigate the relationship between product diversification and the stability of sales and employment. We find that contrary to portfolio theoretic considerations, more diversified firms exhibit a higher variability of sales and employment. However, the effects are negligibly small from an economics point of view.     

Sukuk vs. conventional bonds: A stock market perspective

The last decade witnessed a wide expansion of Islamic finance in Middle Eastern and Southeast Asian countries. Sukuk issues, which are Islamic financial instruments structured to replicate the cash flows of conventional bonds, have notably proliferated, fuelling the debate on the similarity between Islamic and conventional finance. Using an event study methodology on a sample of Malaysian listed companies, we investigate whether stock market investors react differently to the announcements of sukuk and conventional bond issues. We find that the stock market is neutral to announcements of conventional bond issues, but it reacts negatively to announcements of sukuk issues. We attribute this finding to the excess demand for Islamic investment certificates and to an adverse selection mechanism that favors sukuk issuance by lower-quality debtor companies.     

Archetypes of governance for science and technology labs

While policy-makers understand the vast benefits of publicly funded and not-for-profit research, governance practitioners have the difficult task of defining processes that can best foster high performance for science and technology (S&T) labs not primarily driven by profits. This qualitative study develops a new taxonomy based on two dimensions, the nature of the funding relationship between the parent organisation and the S&T lab and the degree of interdependence between the lab's research units. We discuss the dynamics uncovered for each of the four archetypes with illustrative cases and argue that high-performance governance of S&T labs requires an internal coherence linking the processes of planning, funding and performance evaluation.     

Gesetzliche Mindestlöhne: mit der Einführung kommen die Tücken der Umsetzung

Looking around the world, one realizes that national minimum wages are not uncommon. Yet it is still very difficult to estimate what effects a minimum wage might have in Germany. This is not just a question of how high the minimum wage should be — its impacts would also depend on many details of practical implementation. The present article addresses these issues.     

Ungleiche Verteilung der Einkommen bremst das Wirtschaftswachstum

In Germany in the last decade, corporate incomes have increased much more sharply than private household incomes. At the same time, the inequality of household incomes has increased. High-income households have profited particularly from investment income and self-employment. The income gap has not widened further in recent years, but the high level of inequality already reached in 2005 has resulted in a sustained reduction of consumer spending. What is needed now is a level of income and wealth distribution that will strengthen domestic demand.     

Cross-channel integration – is it valued by customers?

It has been common for retail companies to use multiple channels simultaneously. However, simultaneous use is only the first step in creating a customer-centric multichannel system that demands channel synergies rather than parallel retail formats. Therefore, the perceived integration of customer-related functions and processes between the channels of multichannel systems is analyzed with respect to its significance for customer loyalty and usage of a multichannel system. Drawing on a sample (n) of 981 customers, the results indicate that linkages between retail channels positively affect customer loyalty and verify the importance of establishing a well-integrated – ‘seamless’ as perceived by the customer – multichannel system.     

A note on why more West than East German firms export

Germany is one of the most important exporters of manufacturing goods in the world, but by far not all manufacturing firms in Germany are exporters, and there is a remarkable gap between the share of exporters in all manufacturing firms between West Germany and East Germany. While in West Germany in 2004 about two in three manufacturing plants were exporters, fourteen years after re-unification this share was less than fifty percent in the former communist East Germany. Given that exports play a key role in shaping business cycles and growth in Germany, and the much higher unemployment in East compared to West Germany, promotion of exports by East German firms figure prominently on the policy agenda. However, the reasons for the large difference in the propensity to export between East and West German firms are not yet well understood, not least due to a lack of comprehensive micro data. Using unique new data and a recently introduced non-linear decomposition technique this paper shows that the huge difference in the propensity to export between West and East German plants can only partly be explained by differences in firm size, productivity, and technology intensity.

The Social Construction of Theoretical Landscapes: Some Economics of Economic Theories

Economic theory emerges through interaction among interested participants, with the content of those theories being a product of spontaneous ordering and not scientific planning. At any moment, it is reasonable to expect various theoretical formulations to be in play, some typically receiving greater attention than others. As with spontaneous orders in general, the institutional arrangements within which theorizing occurs are influential though not determinative over the characteristics of theories. In this respect, a distinction is made between theories directed at understanding social processes as open and creative and theories directed at controlling what are treated as closed and deterministic processes. This distinction is illustrated with respect to theorizing about macro phenomena and public phenomena.     

The econometrics of auctions with asymmetric anonymous bidders

We consider standard auction models when bidders’ identities are not-or are only partially-observed by the econometrician. We first adapt the definition of identifiability to a framework with anonymous bids and explore the extent to which anonymity reduces the possibility of identifying private value auction models. Second, in the asymmetric independent private value model which is nonparametrically identified, we generalize Guerre, Perrigne and Vuong’s estimation procedure [Optimal nonparametric estimation of first-price auctions, Econometrica 68 (2000) 525-574] and consider the asymptotic properties of our multi-step kernel-based estimator. Monte Carlo simulations illustrate the practical relevance of our estimation procedure in small data sets.
