Flight Home, Flight Abroad and International Credit Cycles

Abstract: This paper shows that banks exhibit a weaker (stronger) home bias in the extension of new loans when funding conditions in their home country improve (deteriorate) We refer to these changes in home bias as flight home and flight abroad effects, respectively, and show that they are unrelated to the better known flight to quality effect that arises during periods of market turmoil Our results also indicate that global banks amplify the effect of home-grown shocks on foreign countries while they are a stabilizing factor for the supply of credit in their home countries

Herding in Aid Allocation

Abstract: This paper investigates a claim repeatedly made, but never tested, that aid donors herd. To do so it originally uses methodologies developed in finance to measure herding on financial markets, and adapts them to aid allocation. The motivation for studying herding is to improve our understanding of aid allocation beyond observable determinants. If herding is indeed present, then it is likely to shape aid patterns in a significant way by creating aid darlings, orphans, but also by exacerbating aid volatility. Our approach starts by carefully defining aid to avoid including herding-prone aid, such as humanitarian aid and debt relief, and the sets of donors and recipients. Once this is done, herding is measured by directly applying the indexes used in finance to yearly aid data. Results show herding is indeed present, but that it is small. A second step is to introduce modifications to better match the characteristics of aid allocation. The most important in the paper is to change the time horizon. Unlike traders, aid donors commit to an aid partnership over several years, and yearly variations may contain a large part of randomness. Instead of year-to-year changes, we instead use 3- and 5-year allocations to measure herding. With this modification herding is still found to be present, but also of a larger size. It is now similar to what is traditionally found on financial markets. The next, important step is to acknowledge that aid donors' allocation decisions almost surely follow similar determinants and changes in these determinants generate a lot of co-movements. Herding measures by definition interpret these simultaneous decisions as herding, when they merely reflect common views among donors (think about a natural disaster occurring in a country that dramatically increase aid needs). Herding determinants are carefully estimated and their contributions to herding measures are then removed to obtain an estimate free of the effects of observable variables that affect aid allocation. This procedure shows that, even after taking observable factors into account, herding is still present. It suggests other considerations drive herding behavior.

International management of R&D: The Swedish Experience

Abstract: This paper summarizes the results of in-depth case studies of international R&D management in four Swedish multinational corporations. The results suggest that foreign volumes and shares of R&D expenditures are rapidly increasing. Through a rapidly increasing number of foreign acquisitions, foreign R&D laboratories have been added. As part of international rationalization of production, foreign units have been given global product mandates with responsibility both for manufacturing and R&D. In maturing foreign subsidiaries, routine technical activities have often evolved into proper R&D. Tight labour market conditions for engineers in Sweden have made it increasingly necessary to exploit existing technical capacity, regardless of location. Concurrently, companies face new pressures for international coordination and control of R&D. Coordination is required to reduce product differentiation, to facilitate technology transfer and to ensure the technical and market compatibility of products and components developed at different locations but sold as part of total systems. Drawing on the experience in the four investigated companies, the paper discusses how systems and procedures can be developed to meet the need for coordinated international R&D management.

Modelling conditional and unconditional heteroskedasticity with smoothly time-varying structure

Abstract: In this paper, we propose two parametric alternatives to the standard GARCH model. They allow the conditional variance to have a smooth time-varying structure of either additive or multiplicative t ...
