Should We Fear Derivatives?

This paper discusses the extent to which derivatives pose threats to firms and to the economy. After reviewing the derivatives markets and putting in perspective the various measures of the size of these markets, the paper shows who uses derivatives and why. The difficulties firms face in valuing derivatives portfolios are evaluated. Although academics pay much attention to no-arbitrage pricing results, the paper points out that there can be considerable subjectivity in the pricing of derivatives that do not have highly liquid markets. It is shown that the known risks of derivatives portfolios can generally be measured and managed well at the firm level. However, derivatives can create systemic risks when a market participant becomes excessively large relative to particular derivatives markets. Overall, the benefits of derivatives outweigh the potential threats.

Financial Globalization, Corporate Governance, and Eastern Europe

For many countries, the most significant barriers to trade in financial assets have been knocked down. Yet, the financial world is not flat because poor governance prevents firms from being widely held and from taking full advantage of financial globalization. Poor governance has implications for corporate finance as well as for macroeconomics. I show that poor governance in Eastern Europe is accompanied, as expected, by high corporate ownership concentration, low firm valuation, poor financial development, and low foreign participation.

U.S. Banks, Crises, and Bailouts: From Mexico to LTCM

This paper investigates the impact on bank stock prices of emerging market currency crises and bailouts. The stock market distinguishes between banks with exposure to a crisis country and other banks. In general, banks with exposures to a crisis country are affected adversely by currency events and positively by bailouts. Other banks are mostly unaffected by events in countries experiencing a crisis. The paper uses the impact of the LTCM crisis on bank stock prices to put the emerging market events in perspective. The LTCM crisis had no significant contagion effects in the banking sector either, but banks that participated in the LTCM rescue experienced negative stock returns when the rescue was announced.

Making university-industry collaboration work - a case study on the Deutsche Telekom Laboratories contrasted with findings in literature

The growing competition in consumer as well as business customer markets is forcing industry to explore new ways to foster product and service innovations. To increase the clock speed of incremental innovations and raise the number of radical innovations, university-industry collaborations (UIC) are a powerful means discussed by practitioners as well as by scholars. This paper discusses the approach of the Deutsche Telekom Group (DTAG) of building a UIC by creating a separate organization. This organization consists of R&D personnel both from industry and academia and proves to be effective in channelling innovation potential. Being an organization with its own identity and situated on university premises, the Deutsche Telekom Laboratories (DT Laboratories) offer different ways to overcome the cultural, institutional and operational barriers associated with UIC. The case study validates and challenges findings on UIC in literature. The paper closes with practical advices for the establishment and management of UIC and suggestions for further research in this field.university–industry collaboration; technology transfer; technological innovation; basic research; applied research; innovation development; radical innovations; incremental innovations; technology intelligence; explorative capabilities; university-industry research center (UIRC)

The Risks of Financial Institutions

Over the last twenty years, the consensus view of systemic risk in the financial system that emerged in response to the banking crises of the 1930s and before has lost much of its relevance. This view held that the main systemic problem is runs on solvent banks leading to bank panics. But financial crises of the last two decades have not fit the mold. A new consensus has yet to emerge, but financial institutions and regulators have considerably broadened their assessment of the risks facing financial institutions. The dramatic rise of modern risk management has changed how the risks of financial institutions are measured and how these institutions are managed. However, modern risk management is not without weaknesses that will have to be addressed.

The Economics of Conflicts of Interest in Financial Institutions

A conflict of interest exists when a party to a transaction could potentially make a gain from taking actions that are detrimental to the other party in the transaction. This paper examines the economics of conflicts of interest in financial institutions and reviews the growing empirical literature (mostly focused on analysts) on the economic implications of these conflicts. Economic analysis shows that, although conflicts of interest are omnipresent when contracting is costly and parties are imperfectly informed, there are important factors that mitigate their impact and, strikingly, it is possible for customers of financial institutions to benefit from the existence of such conflicts. The empirical literature reaches conclusions that differ across types of conflicts of interest, but overall these conclusions are more ambivalent and certainly more benign than the conclusions drawn by journalists and politicians from mostly anecdotal evidence. Though much has been made of conflicts of interest arising from investment banking activities, there is no consensus in the empirical literature supporting the view that conflicts resulting from these activities had a systematic adverse impact on customers of financial institutions.

Are Financial Assets Priced Locally or Globally?

We review the international finance literature to assess the extent to which international factors affect financial asset demands and prices. International asset pricing models with mean-variance investors predict that an asset's risk premium depends on its covariance with the world market portfolio and, possibly, with exchange rate changes. The existing empirical evidence shows that a country's risk premium depends on its covariance with the world market portfolio and that there is some evidence that exchange rate risk affects expected returns. However, the theoretical asset pricing literature relying on mean-variance optimizing investors fails in explaining the portfolio holdings of investors, equity flows, and the time-varying properties of correlations across countries. The home bias has the effect of increasing local influences on asset prices, while equity flows and cross-country correlations increase global influences on asset prices.

Internal and external R&D: complements or substitutes? Evidence from a dynamic panel data model.

We examine the impact of internal and external R&D on labor productivity in a 6-year panel of 304 innovating firms. We apply a dynamic linear panel data model that allows for decreasing returns to scale in internal and external R&D with a non-linear approximation of changes in the knowledge stock. We find complementarity between internal and external R&D, with a positive impact of external R&D only evident in case of sufficient internal R&D. The findings confirm the role of internal R&D in enhancing absorptive capacity and hence the effective utilization of external knowledge. These results suggest that empirical studies examining complementarities between continuously measured practices should adopt more general non-linear specifications to allow for correct inferences.R&D; Panel data; Innovating firms; Knowledge; Empirical study; Specifications;
