Editorial

This paper presents an overview of issues for future research. as identified by the papers appearing in the Special Issue on Innovation in Telecommunications. To this end. we elaborate upon the emergence of a new innovation regime in telecommunications, discuss the performance and sustainability of this new innovation regime, and reflect upon institutional choices for the regime and accompanying policy options. Further research on innovation in telecommunications is advocated, taking up a broad range of issues, including long-term industrial evolution and sustainability concerns in a wide sense.     

SPECTRUM LICENSING AND FLEXIBLE BEAUTY CONTEST DESIGNS

McMillan's (1995) ‘flexibility’ proposition suggests a testable hypothesis about beauty contests spectrum assignments. Such flexibility purportedly allows regulators to pursue social welfare (network deployment) goals. A separate argument is that more competitive beauty contests enhance the probability of assignment. The study concludes that regulators do indeed focus on societal (network deployment) welfare goals. Initially, consideration is given in the immediate term where licenses are awarded based on operator aftermarket commitments. Subsequently, spectrum package attributes and financial performance obligations, specified in the tender documents, come into play to support the networks spread more widely through the population in a timely manner. Finally, the econometric results suggest that more competitive beauty contests enhance the probability of assignment.     

Stock Recommendations in Swedish Printed Media: Leading or Misleading?

Abstract

This paper analyses the initiated and changed recommendations published in six well-known Swedish newspapers and business magazines for the period 1996–2000 using a buy-and-hold abnormal returns (BHARs) approach. The results distinguish between recommendations from analysts and journalists. Buy recommendations were misleading investors, whereas sell recommendations were leading them correctly, overall yielding returns in line with the market. This asymmetry is due to positive information from the management of the company being more intricate to interpret than negative. Both good and bad information provided by the management is generally positively biased, a phenomenon influencing both analyst and journalist recommendations. Following buy and sell recommendations from analysts yielded BHARs in line with those from journalists, which in turn generates returns in line with their peers. Going short in the recommended stocks, irrespective of type and origin, would lead to a 24-month BHAR of 14%.     

Characteristics of a Logistics-Based Business Model

In companies where excellence in logistics is decisive for the outperformance of competitors and logistics has an outspoken role for the strategy of the firm, there is present what we refer to here as a “logistics-based business model.” Based on a multiple case study of three Nordic retail companies, the purpose of this article is to explore the characteristics of such a logistics-based business model. As such, this research helps to provide structure to logistics-based business models and identifies a way forward for companies for whom logistics and distribution are a major concern for the overall strategy of the firm.     

Ist der Fahrplan der Energiewende noch einzuhalten?

The German energy transition represents a policy-driven, sustainability-oriented restructuring of both supply- and demand-side components of the entire energy system by 2050. Whereas the development of renewable energies in the electricity sector is right on track, due to the feed-in tariffs of the German Renewable Energy Sources Act, many other crucial requirements for a successful transition are not, amongst others the improvement of energy effi ciency and the decarbonisation of the transport sector. Contrary to the public discussion, the primary future challenges do not consist in limiting electricity prices or abandoning feed-in support schemes, but rather in coordinating the variety of actors as well as appropriately matching the different system elements (grids, technologies, energy sectors, demand and supply side, etc.). Much remains to be done. By highlighting some examples like the need to take into account future implications of climate change for the energy sector, the consequences of the current crisis in the European Union’s emissions trading scheme and the need for a cautious adjustment of the EEG, the paper argues that the major challenges regarding the German energy transition mainly go beyond the current policy-driven and short-term discussion of energy prices. Germany’s pioneering attempt to integrate steadily increasing share of non-dispatchable electricity from renewable sources is challenging the stability of the system. Several characteristics in the current selfregulating system are identifi ed and analysed, which reveal themselves as potential weaknesses or shortcomings in the upcoming system.     

Potential economic variables and actual economic policies in Europe

Ignoring for a moment the debate on whether balanced budget rules are a sensible idea from a macroeconomic point of view, there remains a major problem with tying one’s fiscal policy to econometric estimates of potential variables: their notorious unreliability. With every one of its biannual economic forecasts, the EC provides revised estimates of structural parameters that are crucial components of its macroeconometric models and, by extension, its economic policy advice. This article shows that the EC’s econometric estimates of potential growth variables in Europe have been subject to massive revisions since the financial crisis.     

THE BIAS OF THE MULTIPLIER MATRIX WHEN SUPPLY AND USE TABLES ARE STOCHASTIC

The literature on stochastic input–output (I–O) analysis has paid considerable attention to the bias in the Leontief inverse. This paper extends previous studies by assuming supply and use tables (SUTs rather than I–O tables or input coefficients matrices) to be stochastic. This is a natural starting point because SUTs have become the basic data sources for I–O applications. In a Monte Carlo simulation experiment, a given SUT is randomized in two different ways and the effects are determined for eight different multiplier matrices. The analysis is carried out for Spain, Italy, the Netherlands, Germany and Finland, using their SUTs for 2006. The findings indicate that, in general, biases are statistically significant but negligibly small. This corroborates earlier findings obtained for stochastic I–O tables.     

INPUT–OUTPUT ANALYSIS: THE NEXT 25 YEARS

This year marks the 25th anniversary of the International Input–Output Association and the 25th volume of Economic Systems Research. To celebrate this anniversary, a group of eight experts provide their views on the future of input–output. Looking forward, they foresee progress in terms of data collections, methods, theory testing, and focus and scope.     

Panda and elephant – contesting animal icons in Thai tourism

In May 2009, during a period of rising political polarization in Thailand, a cub was unexpectedly born in Chiang Mai's Zoo to a pair of Chinese pandas. The authorities used the occasion to boost the crisis-ridden tourism to the northern Thai city, instigating an unprecedented national craze around the tiny cub, and promoting a massive pilgrimage of domestic visitors to the zoo. In a conspicuous act of protest against the prioritization of the foreign pandas, some elephant keepers in the Ayutthya kraal, painted their animals in panda colors, leading to an implicit contest between the two animal icons. In this case study, the wider theoretical and comparative implications of that contest are analyzed. Whereas previous studies of tourists engagement with captive wild animals paid scant attention to its wider social context, the article examines the cultural and economic background of the contest, and the manner in which it became implicated in the process of political polarization between the societal center and the periphery.
