A longitudinal study of the cause and consequences of changes in diversification in the U.S. pharmaceutical industry 1977–1986

The paper hypothesizes that diversification by firms based in the pharmaceutical industry during the 1977-86 time period was primarily undertaken to reduce the risks associated with being dependent upon a technologically dynamic environment. Consistent with this non-efficiency motive for diversification, declining economic performance is predicted. A longitudinal empirical analysis provides support for these propositions.     

The Division of Labor Under Homogeneity: A Critique of Mises and Rothbard

A bstract .   Even the most passionate defenders of free trade, such as Mises and Rothbard, claim that trade cannot occur under conditions of strict homogeneity of land, labor, and capital. We show that specialization, trade, and the division of labor can emerge even when resources are initially homogenous, due to "natural heterogeneity," economies of scale, and learning.     

Environmental Innovations in Small and Medium Sized Enterprises

Supporting and accelerating the adoption and diffusion of environmental innovations amongst small and medium sized enterprises (SMEs) is a major challenge to environmental policy makers. Research suggests that whilst SMEs possess high flexibility, their innovative capacity may be limited to incremental changes within their existing technology system and network. Twenty case studies examining the innovation adoption process in SMEs in four sectors and in five countries within the ENVIS project (commissioned by the EU) revealed great variety in factors driving this process. Findings indicate that this variation can be attributed to the character of the environmental innovation, the specific business opportunity, the regulatory setting and pressure experienced by the sector. Based on these findings an analytical framework is suggested, whereby the environmental innovative capability of SMEs is conceived as the result of an interplay between the competencies, the network relations and the strategic orientation of the company (the 'dynamic triangle'). This indicates that policy to support SME's adoption of environmental innovations has to take an integrated form, i.e. addressing and developing competence, networks and strategic orientation of SMEs simultaneously whilst remaining systemic and context sensitive.     

Access Pricing,Quality Degradation,and Foreclosure in the Internet

Access to both a local and a global network is needed in order to get complete connection to the Internet. The purpose of this article is to examine the interplay between those two networks and how it affects the domestic public policy towards a domestic provider of local access. We find that a cost-oriented regulation is detrimental to domestic welfare, because it shifts profit to the foreign provider of global access. The optimal policy is that the regulator commits itself to set an access price above costs, possibly the same price as in an unregulated market economy. A regulation of the global access price has a non-monotonic effect on domestic welfare, and there is a potential conflict between international and domestic regulation policy.     

Strategic Regulation Policy in the Internet

Some countries are importers while others are exporters of global backbone connectivity. At the same time, input components such as local access are non-traded. This paper analyzes a non-cooperative regulatory game between importing and exporting countries, assuming that the prices of both traded and non-traded inputs can be regulated. We show that exporting countries choose a more restrictive regulation of non-traded goods than importing countries do. We further show that a requirement of international non-discrimination may hurt importing countries, and give firms producing traded inputs incentives to invest in quality degradation.     

Monetary incentives and environmental concern. Effects of a differentiated garbage fee

Market-based instruments, i.e., economic incentives and disincentives, are gaining popularity in environmental policy. However, research on the effectiveness of economic incentives for regulating environmentally relevant consumer behaviour demonstrates convincingly that the implementation of this instrument is based on inadequate assumptions concerning the motivation guiding consumer behaviour. In this paper it is argued that stronger focus should be placed on studying how the regulation instrument influences the perception of the environmentally relevant activity that it was meant to regulate. The attitudes of Danish citizens towards differentiated garbage fees (implying a relatively small economic incentive) and the impact of its implementation on the attitude towards recycling are analysed. The attitude towards differentiated garbage fees is primarily determined by the perceived equity of differentiated garbage fees and its perceived effectiveness with regard to combating waste problems. The most important determinant of the attitudes towards recycling activities is the expected environmental and public benefits. However, empirical support is found for the hypothesis that the use of monetary incentives at the consumer level may re-frame the recycling issue into the sphere where private cost-benefit calculations apply. The negative effects of this re-framing can more than outweigh the positive impact of the monetary incentive on attitudes and behaviour.

Zusammenfassung Monetäre Anreize und Umweltbewutsein. Die Wirkung differenzierter Müllgebühren. Marktkonforme Instrumente wie ökonomische Anreize oder Strafen werden in der Umweltpolitik immer populärer. Allerdings zeigen Forschungsergebnisse über die Wirksamkeit ökonomischer Anreize für die Regulierung umweltrelevanten Konsumentenverhaltens, da\ die Anwendung dieses Instrumentes auf unzweckmä\igen Annahmen über die Motivation beruht, die dem Verbraucherverhalten zugrunde liegt. In diesem Beitrag wird gefordert, da\ die Frage stärker in den Mittelpunkt gerückt werden mu\, wie das Regulierungsintrument die Wahrnehmung des umweltrelevanten Verhaltens beeinflu\t, das reguliert werden soll. Eine empirische Studie untersucht die Einstellungen dänischer Bürger gegenüber differenzierten Abfallgebühren (die einen relativ kleinen ökonomischen Anreiz bieten) und die Wirkung dieser Ma\nahme auf die Einstellung gegenüber der Wiederverwertung. Die Einstellung zu differenzierten Müllgebühren wird in erster Linie durch ihre wahrgenommene Gerechtigkeit bestimmt und durch ihre wahrgenommene Wirksamkeit gegenüber den Müllproblemen. Die wichtigsten Determinanten der Einstellung gegenüber der Müllwiederverwertung sind ihre erwarteten allgemeinen Umweltvorteile. Allerdings sprechen die Daten für die Hypothese, da\ monetäre Anreize das Thema der Müllwiederverwertung auf Verbraucherebene auf das Niveau privater Nutzen-Kosten-Kalkulationen herunterdrücken. Die negativen Effekte dieser Verschiebung könnten die positiven Wirkungen monetärer Anreize auf Einstellung und Verhalten sogar überkompensieren.

Implied Volatility of Interest Rate Options: An Empirical Investigation of the Market Model

We analyze the empirical properties of the volatilityimplied in options on the 13-week US Treasury bill rate. These options havenot been studied previously. It is shown that a European style put optionon the interest rate is equivalent to a call option on a zero-coupon bond.We apply the LIBOR market model and conduct a battery of validity tests tocompare three different volatility specifications: contact, affine, and exponentialvolatility. It appears that the additional parameter in the affine and theexponential volatility function is not justified. Overall, the LIBOR marketmodel fares well in describing these options.     

Partner‐diversity effects on alliance termination in the early stage of green alliance formation: Empirical evidence from carbon‐emission reduction projects in Latin America

Partner diversity is a key influencer in interorganizational alliances, and several empirical studies have shown that its outcomes are contingent on alliance‐specific factors. We extend this research as well as the growing literature on green alliances, in which partner diversity is uniquely high. Specifically, we examine partner‐diversity effects on alliance termination in the early stage of green alliance formation. We hypothesize that in this context, size disparity increases termination likelihood, whereas organizational variety and cultural separation have the opposite effect. To test our hypotheses, we use a sample of 366 alliance projects located in Latin America and submitted to the Kyoto Protocol's Clean Development Mechanism for evaluation, validation, and registration from 2004 to 2014. Our findings contribute to several research streams and provide practical guidance for successful formation of alliances focused on environmental protection.     

Consumption Fluctuations and Expected Returns

This paper introduces a novel consumption-based variable, cyclical consumption, and examines its predictive properties for stock returns. Future expected stock returns are high (low) when aggregate consumption falls (rises) relative to its trend and marginal utility from current consumption is high (low). We show that the empirical evidence ties consumption decisions of agents to time variation in returns in a manner consistent with asset pricing models based on external habit formation. The predictive power of cyclical consumption is not confined to bad times and subsumes the predictability of many popular forecasting variables.
