Innovation and corporate sustainability: An investigation into the process of change in the pharmaceuticals industry

Although there has been considerable research effort directed at refining the content of corporate environmental performance, e.g. corporate environmental reporting and accounting, there has been relatively little empirical investigation to date on the process of corporate eco‐change. This research reports on the quantitative and qualitative results of a survey of German and UK pharmaceuticals firms, which evaluated the significance of the various incentives, both intra‐firm and external to the organization, that have stimulated eco‐change. We find that, although the industry is one that has been characterized by voluntary agreements and proactive behaviour in the past, regulation still remains the main driver for sustainability improvements. New technology is the second most important driver. Stakeholder dialogue and inter‐firm cooperation were both revealed to be relatively weak forces for eco‐change. The study also tested the validity of the conventional neo‐classical economic world‐view of innovation in firms versus a more radical co‐evolutionary one. The former assumes that firms respond only to profit signals and do so efficiently, whereas the latter assumes that change is path dependent; i.e., the firms’ norms and routines and past experiences are influential. We find that, although the neo‐classical perspective stands up to our empirical investigation of eco‐innovation to some degree, the co‐evolutionary approach better captures the complexity of the corporate eco‐change process.

Trends and cycles in regional economic growth: How spatial differences shaped the Swedish growth experience from 1860–2009

Using a novel dataset of regional GDP per worker from 1860 to 2009, this paper analyzes communalities in regional long-term growth trajectories for 24 Swedish regions. Wavelet Analysis and Principal Component Analysis are used to decompose regional growth trajectories and assess the extent that regional growth patterns share common trends and cyclical properties. The study found that regional growth trends show strong common features among groups of regions in Sweden. Natural-resource-rich regions benefited from the First Industrial Revolution. Contrary to regional development in many other European economies, a growth surge in Sweden later benefited virtually the whole country during the Second Industrial Revolution. The countrywide trend of growth slowed in the 1970s when the metropolitan regions became the main growth engines. In mid- and short-term cyclical movements, regions display more heterogeneous growth patterns, and we find evidence of mid-term, sequential lead–lag patterns in regional growth, especially between urban cores and the periphery.     

Who moves first? An intensity-based measure for information flows across stock exchanges

In this paper we propose an innovative measure for information flows between stock exchanges. We develop an intensity-based information share using Russell’s (1999) autoregressive conditional intensity model. Thereby we maintain the irregular nature of financial high frequency data and use durations and timing of price changes to determine the informationally dominant market. From our empirical application to US-listed Canadian stocks we conclude that the home market mostly reflects information first. On the basis of a cross-sectional analysis we find a positive correlation between the intensity-based information share and liquidity.     

The Solar Shakeout – Capital Market Reactions to Bankruptcy Announcements in the German Solar Industry

This paper investigates how bankruptcy announcements in the German solar industry affect the stock market returns of announcing firms and their competitors. We show that German solar firms experience negative capital market reactions to their own bankruptcy announcements and to the announcements of their competitors. Cross-sectional analysis reveals that these negative information externalities are magnified by higher leverage. Further analysis also indicates that these negative information externalities are valuable predictors in short-term default probability models.     

Identifying development blocks—a new methodology

The paper specifies a quantitative methodology for exploring development blocks. The concept of ‘development block’ was a major contribution to the historical analysis of industrial transformation by the late Erik Dahmén, but development blocks have mainly been analyzed by qualitative methods and indirect indicators and not statistically identified. In this paper, development blocks are identified by means of a combination of co-integration analysis and Granger causality. Using these techniques, we are able to identify two partially overlapping development blocks in the Swedish economy, formed around the electricity generating sector: one with metal, metal goods, machinery and railways; and another with pulp and paper, chemicals, and machinery.
