The macro-financial factors behind the crisis: Global liquidity glut or global savings glut?

It has been argued that the global financial crisis 2007–2009 was intrinsically related to two largely unprecedented phenomena in the global economy: (i) exceptionally benign financial market conditions as mirrored in historically low risk premia and buoyant asset price developments as well as (ii) an unprecedented widening of external imbalances. This paper explores to what extent these global trends can be understood as a reaction to three structural shocks to the macro-financial environment of the global economy: (i) monetary shocks (“excess liquidity” hypothesis), (ii) preference shocks (“savings glut” hypothesis), and (iii) investment shocks (“investment drought” hypothesis). In order to uniquely identify these shocks in an integrated framework, we estimate structural VARs for the two main regions with widening imbalances, the United States and emerging Asia, using sign restrictions that are compatible with standard New Keynesian and Real Business Cycle models. Our results show that (US) monetary policy shocks explain the largest part of the variation in imbalances and financial market prices. We find that savings shocks and investment shocks explain less of the variation. Hence, a “liquidity glut” may have been a more important driver of real and financial imbalances in the US and emerging Asia that ultimately triggered the global financial crisis.     

The Impact of the 9/11 Events on the American and French Stock Markets

Markets reacted strongly to the World Trade Center attacks both in Europe and in the United States. The extent of this crisis was difficult to assess at the time, underlining the need for a specific tool to measure the magnitude of financial crises. A first measure was recently proposed and applied to the foreign exchange market by Zumbach et al. (2000a,b ). Their measure relies on an analogy with geophysics; the related index of market shocks (IMS) that we propose here is also the counterpart of the Richter scale used for earthquakes. We apply this measure on the French and the American stock markets to put large market events into perspective. The crisis triggered by the September attacks was actually the worst since 1987, and the ninth worst when compared to major historical ones.     

Non‐linear geographics and the economics of transition and democratization1

The purpose of this study is to analyse the effects of geography on the transition process in authoritarian political regimes, and to investigate the nature of the links between political change, economic reforms and geographical location. A simple model of transition and democratization is presented wherein we show that the effectiveness of repression by the incumbent elite is a negative function of the distance to the ‘free world’. In consequence, geography has conflicting effects on shifts in political power. This article provides a rationale for the counterintuitive fact that the first authoritarian country to start a transition process towards democratization is not necessarily the one nearest to the free world.     

Marketing innovation: a systematic review

ABSTRACT

This study aims to investigate the development of ‘marketing innovation’ defined as the implementation of new marketing practices involving significant changes in the design, distribution, promotion or pricing of a product or service. We conduct a systematic review to provide conceptual, methodological and thematic guidance for scholars interested in studying marketing innovation. Our findings suggest while marketing innovation is often merged with the dominant technological focus underpinning product or service innovation, there is a growing trend to consider the innovation potential offered by the development of new distribution channels, branding strategies, communication types or pricing mechanisms. Digitisation, a key driver for marketing innovation, enables new communication methods, branding strategies, offering designs, and transaction settings. There is a growing trend to focus on cocreation, service-dominant logic and user community perspectives.     

Spillover effects and conditional dependence

A better understanding of cross-market linkages and interactions would help to better manage international financial exposure. So far, no attempt has been made to investigate the degree of price and volatility spillovers in a non-Gaussian conditional framework. We present a new model for these transmission mechanisms that relies on asymmetric-t marginal distributions and a copula function to characterize the conditional dependence. Rendering the dependence parameter time varying, we investigate how the dependence structure is affected by stock return innovations.     

Learning from peers' stock prices and corporate investment

Peers' valuation matters for firms' investment: a one standard deviation increase in peers' valuation is associated with a 5.9% increase in corporate investment. This association is stronger when a firm's stock price informativeness is lower or when its managers appear less informed. Also, the sensitivity of a firm's investment to its stock price is lower when its peers' stock price informativeness is higher or when demands for its products and its peers' products are more correlated. Furthermore, the sensitivity of firms' investment to their peers' valuation drops significantly after going public. These findings are uniquely predicted by a model in which managers learn information from their peers' valuation.     

Methodological Advances in DEA: A survey and an application for the Dutch electricity sector

We survey the methodological advances in DEA over the last 25 years and discuss the necessary conditions for a sound empirical application. We hope this survey will contribute to the further dissemination of DEA, the knowledge of its relative strengths and weaknesses, and the tools currently available for exploiting its full potential. Our main points are illustrated by the case of the DEA study used by the regulatory office of the Dutch electricity sector (Dienst Toezicht Elektriciteitswet; Dte) for setting price caps.     

Public research/industry relationships: Efficiency conditions

If economists of technical change dealt with the public research/industry interface, the literature lacks empirical contributions. The present paper is clearly empirical. It investigates the efficiency of the relationships between public research institutions and industry from the point of view of the firm looking for solutions to its problems. The empirical work is based on the study of 32 cases of partnerships in France. It suggests that the efficiency of the interface depends on the context (nature of innovations, public research skills needed, duration of relationships, technological strategies of firms) and on the strategies of public research institutions (organizational linkages adopted). Four hypotheses are examined to test these efficiency conditions.     

Triggers,templates and twitches in the tracking of emerging strategic issues

A longitudinal investigation of group tracking of potential new applications and markets created by an emerging technology (cellular telephones) is used to gain more understanding of the shifts of cognitive frames of reference in the environmental tracking of emerging strategic issues. The dynamics of frame of reference shifts is examined through the derivation and operationalization of the concepts of templates, triggers and twitches. The results posit that examining the frame of reference shifts can be more informative than examining the frames themselves. Implications for strategic management practice and research are addressed.
