The Liquidity Premium of Safe Assets: The Role of Government Debt Supply

IWH Discussion Papers,
No. 11,
2017
Abstract
The persistent premium of government debt attributes to two main reasons: absolute nominal safety and liquidity. This paper employs two types of measures of government debt supply to disentangle the safety and liquidity part of the premium. The empirical evidence shows that, after controlling for the opportunity cost of money, the quantitative impact of total government debt-to-GDP ratio is still significant and negative, which is consistent with the theoretical predictions of the CAPM with utility surplus of holding convenience assets. The relative availability measure, the ratio of total government liability to all sector total liability, separates the liquidity premium from the safety premium and has a negative impact too. Both theoretical and empirical results suggest that the substitutability between government debt and private safe assets dictates the quantitative impact of the government debt supply.

College Choice, Selection, and Allocation Mechanisms: A Structural Empirical Analysis
J.-R. Carvalho, T. Magnac, Qizhou Xiong
Quantitative Economics,
No. 3,
2019
Abstract
We use rich microeconomic data on performance and choices of students at college entry to analyze interactions between the selection mechanism, eliciting college preferences through exams, and the allocation mechanism. We set up a framework in which success probabilities and student preferences are shown to be identified from data on their choices and their exam grades under exclusion restrictions and support conditions. The counterfactuals we consider balance the severity of congestion and the quality of the match between schools and students. Moving to deferred acceptance or inverting the timing of choices and exams are shown to increase welfare. Redistribution among students and among schools is also sizeable in all counterfactual experiments.

College Choice and the Selection of Mechanisms: A Structural Empirical Analysis
J.-R. Carvalho, T. Magnac, Qizhou Xiong
Abstract
We use rich microeconomic data on performance and choices of students at college entry to study the interaction between the revelation of college preferences through exams and the selection of allocation mechanisms. We propose a method in which preferences and expectations of students are identified from data on choices and multiple exam grades. Counterfactuals we consider balance costs arising from congestion and exam organization. Moving to deferred acceptance or inverting the timing of choices and exams are shown to increase welfare. Redistribution among students or schools is sizeable in all counterfactual experiments.

College Choice Allocation Mechanisms: Structural Estimates and Counterfactuals
J.-R. Carvalho, T. Magnac, Qizhou Xiong
Abstract
We evaluate a simple allocation mechanism of students to majors at college entry that was commonly used in universities in Brazil in the 1990s and 2000s. Students first chose a single major and then took exams that select them in or out of the chosen major. The literature analyzing student placement, points out that this decentralized mechanism is not stable and is not strategy-proof. This means that some pairs of major & students can be made better off and that students tend to disguise their preferences using such a mechanism. We build up a model of performance and school choices in which expectations are carefully specified and we estimate it using cross-section data reporting choices between two medical schools and grade performances at the entry exams. Given those estimates, we evaluate changes in selection and students’ expected utilities when other mechanisms are implemented. Results highlight the importance of strategic motives and redistributive effects of changes of the allocation mechanisms.

Housing Consumption and Macroprudential Policies in Europe: An Ex Ante Evaluation
Antonios Mavropoulos, Qizhou Xiong
IWH Discussion Papers,
No. 17,
2018
Abstract
In this paper, we use the panel of the first two waves of the Household Finance and Consumption Survey by the European Central Bank to study housing demand of European households and evaluate potential housing market regulations in the post-crisis era. We provide a comprehensive account of the housing decisions of European households between 2010 and 2014, and structurally estimate the housing preference of a simple life-cycle housing choice model. We then evaluate the effect of a tighter LTV/LTI regulation via counter-factual simulations. We find that those regulations limit homeownership and wealth accumulation, reduces housing consumption but may be welfare improving for the young households.

Eastern Germany in the process of catching-up: the role of foreign and Western German investors in technological renewal
Jutta Günther, Oliver Gebhardt
Eastern European Economics,
No. 3,
2005
Abstract
Foreign direct investment as a means to support system transformation and the ongoing process of catching-up development has caught researcher’s attention for a number of Central and Eastern European countries. Not much research, however, has been carried out for East Germany in this respect although FDI plays an important role in East Germany too. Descriptive analysis by the use of unique survey data shows that foreign and West German affiliates perform much better with respect to technological capability and labor productivity than domestic companies in East Germany. The results of the regression analysis, however, show that it is not the status of ownership as such that forms a significant determinant of innovativeness in East Germany but rather general firms specific characteristics attached to it such as firm size, export-intensity, technical state of the equipment, and R&D activities. Due to the fact that foreign and West German affiliates perform better with respect to exactly all of these characteristics, they can be considered as a means to support the process of technological renewal and economic development.

Getting out of the ivory tower – New perspectives on the entrepreneurial university
Jutta Günther, Kerstin Wagner
European Journal of International Management,
2008
Abstract
Based on theoretical considerations about the ‘third mission’ of
universities and the discussion of different types of university-industry relations, we conclude that the entrepreneurial university is a manifold institution with direct
mechanisms to support the transfer of technology from academia to industry
as well as indirect mechanisms in support of new business activities via
entrepreneurship education. While existing literature usually deals with one or
another linking mechanism separately, our central hypothesis is that direct and
indirect mechanisms should be interrelated and mutually complementary. We
emphasise the importance of a more holistic view of the entrepreneurial university
and empirically investigate the scope and interrelatedness of direct technology
transfer mechanisms and indirect mechanisms, such as entrepreneurship education
at German universities. We find a variety of activities in both fields and most
universities’ technology transfer facilities and the providers of entrepreneurship
education co-operate in support of innovative start-ups.

Internationale FuE-Standorte
Expertenkommission Forschung und Innovation (Hrsg.), Studien zum deutschen Innovationssystem Nr. 11-2013, Berlin,
No. 11,
2013
Abstract
In dieser Schwerpunktstudie wird die Internationalisierung von Forschung und Entwicklung (FuE) aus deutscher Perspektive untersucht. Aktuelle Trends wurden auf Basis der internationalen FuE-Statistik identifiziert. Darüber hinaus werden patentbasierte Indikatoren berechnet, die vor allen Dingen zu den Technologiefeldern der erfinderischen Aktivitäten deutscher Unternehmen im Ausland neue Erkenntnisse liefern. Eine mikroökonometrische Analyse gibt Aufschluss über die relevanten Standortfaktoren für ausländische FuE in Deutschland und der EU27. Zusätzlich wurden neue Befragungsdaten zu FuE deutscher Unternehmen an „neuen Standorten“ in Ost- und Mitteleuropa analysiert. Abschließend wurden an Hand eines Datensatzes europäischer multinationaler Unternehmen sowie der Fallstudie eines deutschen Konzerns strategische Faktoren und Managementpraktiken identifiziert, welche den Wissenstransferin multinationalen Unternehmen beeinflussen.

Lebenswelt im Umbruch: Strukturwandel und regionale Entwicklung
Alexander Kubis
D. Gregosz (Hrsg.), Wo steht Ostdeutschland in zehn Jahren? Zukunftsperspektiven der „Jungen Länder”,
2010
Abstract
Ostdeutsche Regionen befinden sich auch zwanzig Jahre nach der Herstellung der Einheit Deutschlands in einem anhaltenden Prozess des Strukturwandels. Dieser Strukturwandel ist durch transformationsbedingte Besonderheiten gekennzeichnet. Zwar ist die Transformation im Sinne der Übernahme marktwirtschaftlicher Institutionen längst abgeschlossen. In der Post-Transformationsphase zeigen sich allerdings strukturelle Besonderheiten, die ihre Ursprünge teils in der Entwicklung im Osten Deutschlands in der zentralverwaltungswirtschaftlichen Entwicklungsperiode und teils in den Entwicklungsmustern nach dem Übergang zur Marktwirtschaft haben. Obwohl die neuen marktwirtschaftlichen institutionellen Rahmenbedingungen für alle Regionen in Ostdeutschland die gleichen sind, zeigen sich regionale Unterschiede beim wirtschaftlichen Erfolg, d. h. bei Wachstum und Wohlstand. Mit Rücksicht auf die räumliche Differenzierung liegt es nahe, nicht mehr nur pauschale Vergleiche der Wirtschaftskraft und der dahinter stehenden Faktoren zwischen Ost- und Westdeutschland vorzunehmen, sondern die unterschiedlichen Entwicklungen innerhalb Ostdeutschlands, etwa in Mitteldeutschland, Berlin oder der Thüringer Städtekette mit zu berücksichtigen. Im Folgenden wird auf wichtige Aspekte der in der Post-Transformationsphase herausgebildeten Sektoral-, Funktional- und Unternehmensgrößenstrukturen sowie den regionalen Strukturwandel eingegangen. Im Anschluss wird der demographische Wandel thematisiert, der für die künftige wirtschaftliche Entwicklung in Ostdeutschland eine zentrale Herausforderung darstellt.
