Price Dynamics and Consumer Learning

This paper studies the price dynamics induced by strategic firm behavior in the presence of consumer learning about the uncertain quality differential of the products offered by a duopoly. It is found that consumers learn slowly and that prices converge also slowly to full-information levels. A consequence is that the incentives affirms to manipulate consumers' beliefs are persistent. Although pricing tends to be aggressive at the early stages, and average prices eventually increase over time, price wars may occur at intermediate stages of the product life cycle.

Does international research and development increase patent output? An analysis of Japanese pharmaceutical firms

Internationalizing research and development is often advocated as a strategy for fostering the development of technological capabilities. Although firms conduct international R&D to tap into knowledge bases that reside in foreign countries, we argue that in order to benefit from international R&D investments firms must already possess research capabilities in underlying or complementary technologies. We examine the international R&D expansion activities, research capabilities, and patent output of 65 Japanese pharmaceutical firms from 1980 to 1991. We find that firms benefit from international R&D only when they possess existing research capabilities in the underlying technologies. In addition to refining our understanding of when international R&D enhances firm innovation, our results integrate asset‐seeking and asset‐based theories of foreign direct investment. Internationalizing R&D to tap into foreign knowledge bases is consistent with asset‐seeking theories of foreign direct investment, while the contingent nature by which firms benefit from international R&D is consistent with asset‐based theories of foreign direct investment and the notion of absorptive capacity.

Consumer involvement and acceptance of biotechnology in the European Union: a specific focus on Spain and the UK

Biotechnology stands out as a clear‐cut example of an industry where legislation on new technologies has been shown to be linked with public attitudes. Indeed, consumer consultation has played a leading role in the acceptance of genetically modified (GM) food as well as in government policy and legislation. This paper examines the issue of consumer consultation by analysing how public opinion has conditioned the acceptance of GM food in the European Union in general and specifically in Spain and the UK. We draw upon the evidence of two Eurobarometer surveys (46.1 and 52.1) to argue that consumer decision making on new technologies is an information‐dependent factor explaining consumer rejection to non‐transparent introduction of GM food. Individuals feel ill‐prepared to make decisions and rely on trusted information advisors such as consumer organizations. Findings suggest significant information dependency as well as widespread heterogeneity in attitudes towards the applications of biotechnology. Finally, the role played by information channels indicates that consumer participation should precede the adoption of communication policies, as they might need to adapt to the specific cultural characteristics of each country.     

Public information releases, private information arrival and volatility in the foreign exchange market

This paper estimates the impact of market activity and news on the volatility of returns in the exchange market for Japanese Yen and US dollars. We examine the effects of news on volatility before, during and after news arrival, using three categories of news. Market activity is proxied by quote arrival, separated into a predictable seasonal component and an unexpected component. Results indicate that both components of market activity, as well as news releases, affect volatility levels. We conclude that both private information and news effects are important determinants of exchange rate volatility. Our finding that unexpected quote arrival positively impacts foreign exchange rate volatility is consistent with the interpretation that unexpected quote arrival serves as a measure of informed trading. Corroborating this interpretation is regression analysis, which indicates that spreads increase in the surprise component of the quote arrival rate, but not in the expected component. The estimated impact of a unit increase in unexpected quote arrival and the range of values observed for this variable imply an important volatility conditioning role for informed trading.     

Location and the Growth of Nations

Does a country‘s long-term growth depend on what happensin countries that are nearby? Such linkages could occur for avariety of reasons, including demand and technology spillovers.We present a series of tests to determine the existence of suchrelationships and the forms that they might take. We find thata country‘s growth rate is closely related to that of nearbycountries and show that this correlation reflects more than theexistence of common shocks. Trade alone does not appear responsiblefor these linkages either. In addition, we find that being neara large market contributes to growth.
