In their innovative and frequently cited study on the impact watching television (TV) has on income aspirations and happiness, Luigino Bruni and Luca Stanca 2006, henceforth B&S) offer an alternative explanation of Easterlin's income-happiness paradox: “television viewing in contemporary society, by raising material aspirations, contributes to offset the effect of higher income on individual happiness” (B&S, p. 225). More generally, the paper contributes to the literature of economic psychology, addressing the determinants and formation of preferences. While the theoretical analysis of B&S and the hypothesis on the effect of TV on material aspirations are well-grounded, the empirical evidence they present to corroborate the TV hypothesis is rather weak. After correcting a technical inaccuracy of B&S' empirical analysis one obtains results which no longer confirm a significant, positive and robust impact of TV consumption on material aspirations. As discussed in the third section, the revised empirical result does not disprove B&S' main hypothesis on the role of TV in shaping individual preferences. However, it suggests applying a more direct approach of measuring the effect of TV on aspiration than that performed in B&S's empirical analysis.

The paper presents estimates for the impact of related variety, unrelated variety and the functions a region performs in the production process on regional employment growth in Germany. We argue that regions benefit from the existence of related activities that facilitate economic development. Thereby the sole reliance of the related and unrelated variety concept on standard industrial classifications (SIC) remains debatable. We offer estimations for establishing that conceptual progress can be made when the focus of analysis goes beyond solely considering industries. We develop an industry-function based approach of related and unrelated variety and test our hypothesis by the help of spatial panel approach. Our findings suggest that related variety as same as unrelated variety facilitate regional employment growth in Germany. However, the drivers behind these effects do differ. While the positive effect of related variety is driven by high degrees of relatedness in the regional “R&D” and “White-Collar”-functions, the effects of unrelated variety are spurred by “Blue Collar”-functions in this period.

In the literature on environmental innovations R&D collaborations have been identified as a critical determinant of a firm’s environmental innovation performance. However, the literature suggests that R&D collaboration is not always beneficial. Therefore, a more elaborated analysis of the effects of R&D collaborations on a firm’s environmental innovation performance is necessary. This paper investigates the impact of R&D col-laborations with different partner types such as customers, competitors, suppliers, uni-versities, governmental research institutes, consultants and other firms within the same firm group on a firm’s environmental innovation performance. In addition, this paper addresses the question of whether the diversity of R&D collaboration partners is im-portant for the environmental innovation performance. Firm-level data from 2,337 Ger-man service and manufacturing firms are used in the regression analysis. The results suggest that R&D collaboration with suppliers, customers, universities, governmental research institutes, consultants and other firms within the same firm group has a signifi-cantly positive impact on a firm’s environmental innovation performance, whereas col-laboration with competitors has no significant impact. The diversity of R&D collaboration partners has a significantly positive impact on a firm’s environmental innovation performance.

The signals approach as an early-warning system has been fairly successful in detecting crises, but it has so far failed to gain popularity in the scientific community because it cannot distinguish between randomly achieved in-sample fit and true predictive power. To overcome this obstacle, we test the null hypothesis of no correlation between indicators and crisis probability in three applications of the signals approach to different crisis types. To that end, we propose bootstraps specifically tailored to the characteristics of the respective datasets. We find (1) that previous applications of the signals approach yield economically meaningful results; (2) that composite indicators aggregating information contained in individual indicators add value to the signals approach; and (3) that indicators which are found to be significant in-sample usually perform similarly well out-of-sample.

Wissensintensive Interaktionen sind mit einer Reihe von Vor- und Nachteilen für die beteiligten Akteure verbunden. Deshalb hat sich ein Literaturstrang entwickelt, welcher der Fragestellung nachgeht, wie sich FuE-Kooperationen auf die Leistungsfähigkeit von Firmen und Regionen auswirken. Diese Studien kommen zu unterschiedlichen Ergebnissen. Das Papier versucht die verschiedenen Ergebnisse der Literatur zusammenzufassen. Ein weiteres Ziel ist es, die in der Literatur verwendeten Methoden zur Bearbeitung der Fragestellung kritisch zu diskutieren. Zudem geht das Papier der Frage nach, inwiefern die in der Literatur verwendeten Methoden und Ansätze die Ergebnisse der Studien beeinflussen. Zur Bearbeitung dieser Fragestellungen wird eine Metaanalyse der relevanten Literatur durchgeführt. Dabei wird gezeigt, dass FuE-Kooperationen einen positiven Effekt auf die Leistungsfähigkeit von Firmen und Regionen haben. Zudem gibt es starke Evidenz dafür, dass die verwendeten Methoden und Ansätze die Ergebnisse der Studien beeinflussen.

This paper analyses the impact of vertical grants on local public sector efficiency. First, we develop a theoretical model in which the bureaucrat sets the tax price while voters choose the quantity of public services. In this model, grants reduce efficiency if voters do not misinterpret the amount of vertical grants the local bureaucrats receive. If voters suffer from fiscal illusion, i.e. overestimate the amount of grants, our model yields an ambiguous effect of grants on efficiency. Second, we use the model to launch a note of caution concerning the inference that can be drawn from the existing cross-sectional studies in this field: Taking into account vertical financial equalization systems that reduce differences in fiscal capacity, empirical studies based on cross-sectional data may yield a positive relationship between grants and efficiency even when the underlying causal effect is negative. Third, we perform an empirical analysis for the German state of Saxony-Anhalt, which has implemented such a fiscal equalization system. We find a positive relationship between grants and efficiency. Our analysis shows that a careful reassessment of existing empirical evidence with regard to this issue seems necessary.

Es wird häufig davon ausgegangen, dass der Standortwettbewerb während der vergangenen Jahrzehnte aufgrund verschiedener externer Veränderungen deutlich zugenommen und zugleich sein Gesicht verändert hat. Moderne stadt- und regionalökonomische Theorien lassen es naheliegend erscheinen, dass bestimmte Faktoren an Gewicht gewonnen und damit veränderte Bedingungen für den Wettbewerb zwischen Städten und Regionen geschaffen haben. Die Intention des Beitrags besteht darin, mit Hilfe von Fallstudien mehr Licht in diese Veränderungen zu bringen.

Der Beitrag basiert auf Arbeiten einer interdisziplinären Arbeitsgruppe der Akademie für Raumforschung und Landesplanung (ARL). Im ersten Teil wird auf der Grundlage vorliegender theoretischer und empirischer Literatur zum Standortwettbewerb eine systematische Klassifizierung neuerer Tendenzen im Standortwettbewerb erarbeitet. Im zweiten Teil werden die Ergebnisse von Fallstudien präsentiert, die in ausgewählten Städten und Regionen Deutschlands und Österreichs durchgeführt wurden, um die Bedeutung der neueren Tendenzen in der Realität zu identifizieren. Für einige Städte und Regionen konnte festgestellt werden, dass die Tendenz der sinkenden Transport- und Transaktionskosten dort insoweit positive Effekte hatte, weil dort solche Branchen konzentriert sind, die die mit den sinkenden Transport- und Transaktionskosten verbundenen Technologien, Infrastrukturen und Dienstleistungen bereitstellen. Für andere Städte und Regionen konnte ein positiver Einfluss des Abbaus von Grenzbarrieren ermittelt werden. Speziell der Aufholprozess in Ostdeutschland wird allerdings u.a. durch Ballungsvorteile im Westen begrenzt. Obwohl die Effekte der neuen Formen des Standortwettbewerbs auf die wirtschaftliche Performance der betrachteten Raumeinheiten insgesamt eher gering waren, konnte doch eine deutliche Wirkung auf die politischen Entscheidungen zur strategischen Neuaufstellung der Städte und Regionen identifiziert werden.

Innovation is the result of an interactive process. Knowledge-intensive interactions among different partners are associated with a variety of advantages and disadvantages for the actors involved. Therefore, a rich body of literature investigating the impact of R&D collaboration networks on the innovation performance of firms and regions has developed over the last two decades. Those studies come to different results. The aims of this paper are manifold. First, the paper summarizes the results of the relevant literature. Second, a brief overview of the established methods and approaches used in the literature to investigate this research question is given. The third objective is to answer the question whether the achieved results in the literature are predetermined by the employed methods. Finally, relevant gaps for further research are identified. To answer these questions a meta-analysis of the relevant literature is conducted. This study shows that knowledge-intensive interactions have a rather positive impact on the performance of firms and regions. There is also evidence that the employed methods and approaches used in the literature to investigate this research question predetermine the outcome of the research.

Technological innovation is fundamental to firm performance and economic prosperity. The aim of this book is to contribute to an in-depth understanding of collective innovation processes by analyzing publicly funded R&D cooperation and innovation networks in the German laser industry. Standing in a neo-Schumpeterian tradition, it employs interdisciplinary analytical concepts and draws upon a unique longitudinal dataset from the laser industry that covers more than two decades of observations. In brief, the book makes a valuable contribution by exploring how and why firm-specific R&D cooperation activities and network positions, large-scale network patterns, and evolutionary network change processes affect the innovative performance of laser source manufacturers in Germany.

We investigate the role of corporate boards in bank loan contracting. We find that when corporate boards are more independent, both price and nonprice loan terms (e.g., interest rates, collateral, covenants, and performance-pricing provisions) are more favorable, and syndicated loans comprise more lenders. In addition, board size, audit committee structure, and other board characteristics influence bank loan prices. However, they do not consistently affect all nonprice loan terms except for audit committee independence. Our study provides strong evidence that banks recognize the benefits of board monitoring in mitigating information risk ex ante and controlling agency risk ex post, and they reward higher quality boards with more favorable loan contract terms.
