To identify the relevant product markets for Swedish pharmaceuticals, a spatial econometrics approach is employed. First, we calculate Moran's Is for different market definitions and then we use a spatial Durbin model to determine the effect of price changes on quantity sold of own and competing products. As expected, the results show that competition is strongest between close substitutes; however, the relevant product markets for Swedish pharmaceuticals extend beyond close substitutes down to products included in the same class on the four‐digit level of the Anatomic Therapeutic Chemical system as defined by the World Health Organization. The spatial regression model further indicates that increases in the price of a product significantly lower quantity sold of that product and in the same time increase the quantity sold of competing products. For close substitutes (products belonging to the same class on the seven‐digit level of the Anatomic Therapeutic Chemical system), as well as for products that, without being close substitutes, belong to the same therapeutic/pharmacological/chemical subgroup (the same class on the five‐digit level of the Anatomic Therapeutic Chemical system), increased competition is also visible after 1 July 2009 when the latest policy changes with regards to pharmaceuticals have been implemented in Sweden. 相似文献

We present a model in which consumers use product attributes (or labels) and their own beliefs to form expectations about the quality of a product. We use best–worst scaling to elicit beliefs, and study how information may influence these beliefs. In our ranking experiments, participants sort different milk products according to (perceived) nutritional or environmental quality, and we use the resulting choice data to recover beliefs econometrically. In a nutritional quality experiment, we measure how food labels (i.e. front‐of‐package, back‐of‐package and ratio of recommended to restricted nutrients) alter consumers’ beliefs, finding that truthful attribute information may sometimes mislead consumers. The discussion explains how similar experiments could be used to distinguish informative labels from marketing messages. 相似文献

Prior research flags the inherent incompatibilities between for-profit and nonprofit partners and cautions that clashing value creation logics and conflicting identities can stall social innovation in cross sector partnerships. Process narratives of successful versus unsuccessful cross sector partnerships paint a more optimistic picture, whereby the frequency, intensity, breadth, and depth of interactions may afford frame alignment despite partners’ divergent value creation approaches. However, little is known about how cross sector partners come to recognize and reconcile their divergent value creation frames in order to co-construct social value. Using longitudinal narratives of four dyads, we show that partners initially contrast their sector-embedded diagnostic frames and then work together to deliberately develop partnership-specific prognostic frames. We extend the literature on framing by developing a four-stage grounded model of frame negotiation, elasticity, plasticity, and fusion which unpacks the relational process of value creation in cross sector partnerships. Our qualitative analyses further show how partners orchestrate multilevel coordination that helps scaffold and calibrate this relational process of frame fusion. 相似文献

This paper explores the development of market roles and transactions in fuel-efficient stoves in Darfur from 1997 to 2008 as a grounded example of how subsistence markets are socially constructed in post-conflict settings. Using a combination of archival texts, interviews, and real-time discourses by protagonists, this study explains the who, what, why and how of emergent marketplaces by showing how development interventions come to imbue market participants and transactions with socially (re)constructed meanings. The fitful emergence of subsistence marketplaces for fuel-efficient in Darfur is punctuated by development interventions which at times under- or misrepresent market participants and by successes and failures in bringing together trainers, producers, sellers, consumers and users of fuel-efficient stoves. Subsidies and handouts delay and distort the emergence of grassroots demand, choices, and prices; a plurality of competing development interventions re-shape the supply. By the end of 2008, the subsistence market for fuel-efficient stoves catches momentum, engaging over 52% of the Darfuri communities in market transactions for the product. As market participants gain voice and influence they reshape the market to favour mud stoves over metal stoves. Reports by several development organizations suggest that among fuel-efficient stove users, 90% use mud models, and 49% of women who own both mud and metal stoves prefer mud stoves. 相似文献

Firm–employee relationships are dependent on the wider societal context and on the role business plays in society. Changes in institutional arrangements in society affect the perceived responsibilities of firms to their personnel. In this study, we examine mass media discussions about firm–employee relationships from a social responsibility perspective via a longitudinal study in Romanian society. Our analysis indicates how the expected responsibilities of firms towards employees have altered with the changing role of firms in society since the early 1990s. These transformations correspond to the ideological developments, from communist to market-based thinking, which have taken place in post-communist Eastern Europe. More specifically, our study shows how the diminishing expectations of corporate social responsibility (CSR) are linked in mass media to increasingly important talk of human resource management (HRM). HRM is a modern business approach believed to address personnel needs and organisational objectives simultaneously. The congruency of goals in HRM may mistakenly lead to the conclusion that organisations are inherently responsible toward their personnel. We argue that this may not necessarily be the case. HRM, matching well the new free-market ideology in post-communist Eastern Europe, was eagerly embraced in that it defined firm–personnel relationships. In this study, we question whether this was an adequate theoretical perspective for Romanian firms to adopt as it lacks sufficient ethical grounding. We also call for a higher awareness concerning the role of mass media in the management literature, since its current role in constructing the ‘rightness’ and ‘wrongness’ in firm–personnel relationships is hardly considered. 相似文献

Certified B Corporations are ventures that have chosen to embrace third party voluntary social and environmental audits conducted by an entrepreneurial non-profit enterprise called B Lab. In this special issue, we focus on the lifecycle of Certified B Corporations and its relation to the entrepreneurial journey. We highlight research at the intersection of opportunities and prosocial certification to identify patterns and processes which add significant value to ongoing conversations in the field of entrepreneurship while charting new research pathways. We develop a framework of prosocial venturing and certification that pinpoints several elements of likely consequence and curiosity. This offers new insights about the entrepreneurial process that hint at the importance of opportunity, identity metamorphosis and sedimentation/superseding work. We thereby interpret how the exploration of prosociality may add to conversations on how and why ventures resist or embrace change over time, to what effect and ultimately, how opportunities may be reBorn. 相似文献

The recent financial crisis highlighted the importance of better understanding the interaction between macroeconomic and financial conditions. In this paper, we provide a financial social accounting matrix for the Canadian economy and use it to assess the strength of real-financial linkages by calculating and comparing multipliers with and without endogenous financial flows. It is found that taking into account financial flows increases the impact of a final demand shock on output by 4–11%. Moreover, between 2008 and 2009H1, the investment decisions of financial institutions together with the fact that non-financial institutions were unwilling or unable to increase their financial liabilities led to estimated declines in all GDP multipliers. The impact of a final demand shock on GDP declined 3–5%, while the impact of an increase in the availability of investment funds fell 30% and 55% for financial and non-financial corporations, respectively.? 相似文献

A classic dynamic asset allocation problem optimizes the expected final-time utility of wealth, for an individual who can invest in a risky stock and a risk-free bond, trading continuously in time. Recently, several authors considered the corresponding static asset allocation problem in which the individual cannot trade but can invest in options as well as the underlying. The optimal static strategy can never do better than the optimal dynamic one. Surprisingly, however, for some market models the two approaches are equivalent. When this happens the static strategy is clearly preferable, since it avoids any impact of market frictions. This paper examines the question: when, exactly, are the static and dynamic approaches equivalent? We give an easily tested necessary and sufficient condition, and many non-trivial examples. Our analysis assumes that the stock follows a scalar diffusion process, and uses the completeness of the resulting market model. A simple special case is when the drift and volatility depend only on time; then the two approaches are equivalent precisely if (μ (t)? r)/σ2(t) is constant. This is not the Sharpe ratio or the market price of risk, but rather a nondimensional ratio of excess return to squared volatility that arises naturally in portfolio optimization problems. 相似文献

The recent crisis was unusual in its speed and breadth and the type of countries affected.Systemic crises, situations of significant stress in the financial sector, followed by significant policy interventions, often affect several countries at the same time.In the past, though, crises have been largely limited to specific regions or types of economies, the Nordic countries in the early 1990s, Latin America in the mid-1990s, Asia in the late 1990s, and the emerging market economies of the early 2000s.The recent crisis has been unusual in its global nature, affecting countries with a speed and virulence not seen since the Great Depression, with major advance countries and countries recently integrating with the European Union (EU) most affected. 相似文献
