A note on outbound open innovation and firm performance

The concept of open innovation has attracted a lot of interest over the past decade. In light of a relative emphasis on inbound open innovation (indicating an outside‐in process) in prior research, this brief note addresses the relationship between outbound open innovation (indicating an inside‐out process) and firm performance. In particular, it suggests that outbound open innovation may have positive and negative effects on firm performance based on potential benefits and risks of transferring technology. To what degree these effects materialize depends on internal factors, e.g. desorptive capacity, and external factors, e.g. appropriability. Consequently, a proficient internal management of outbound open innovation is critical to avoid its potential risks and to capture its substantial benefits. In this regard, future research may substantially deepen the insights into the relevance and role of outbound open innovation.     

Emerging risk of autoignition and fire in underground coal storage

The risk and prevention of autoignition in underground coal storage facilities are reviewed in the light of the recent incidents of smouldering fires. Also, the opportunities are considered on the efficiency of the alternatives to prevent and extinguish closed-space fires. The complexities in avoiding and extinguishing underground fires are highlighted in the case example, describing the observations and outcome of a smouldering coal fire in the storage. The principles of self-heating and most critical factors in spontaneous combustion such as the condition and quality of coal are fairly well known, but usually only provide partial help in fire prevention. The documented cases and the case example suggest that nitrogen injection can be useful for extinguishing controllable fires. Three-phase foams and oxygen-displacing exhaust gases appear preferable against uncontrolled fires, particularly if access to the fire area is limited or impossible. Otherwise, efficient fire extinction during power plant operation can be challenging, as any air ingress tends to feed the fire and results in losses of the extinguishing agent and the heating value of coal. Methods and indicators for detecting and predicting the ignition are discussed, and improvements are suggested to enhance the storage and plant availability.     

Experience and the unexpected: risk and mitigation issues for operating underground storage silos for coal-fired power plant

Observed autoignition events and extinguishing the resulting smouldering fires in an underground storage system of a coal-fired power plant have provided insight into the array of contributing variables, and some experience on quantifying the risk with alternative scenarios of event initiation, progress and potential mitigation. Although the first attempts to quantify the risk suggest high sensitivity to the sequence of action taken after fire alarm, and no similar storage sites really exist, some recommended preventive, corrective and other mitigating activities can be at least partly defined and improved by using the cumulative experience and parallel efforts in other closed or underground storage sites. However, there are also so-called black (or at least grey) swans: unexpected events for which the facility may be poorly prepared for. In the case of the underground storage silos, such an event was experienced when incoming cold coal during a harsh winter season froze the sewer system that normally protects the stored coal from seepage water. With blocked normal bypass, the seepage water found its way to the coal silos and created large clumps of icy coal that blocked the coal conveyors. Although freezing weather is not unusual at high-latitude power plants, the common methods to combat freezing of coal are mainly useful for open storage sites and above-ground transport. Options for mitigation are discussed, as well as the event chain leading to an event that had never previously occurred. The case is discussed from the point of view of options to prepare for rare or unforeseen events.     

Risk management strategies - before Hominization and after

Selected examples, ranging from birds to pastoralistic nomads and subsisting peasants, indicate that the higher animals adopt foraging strategies similar to individual decision makers in economies without market (subsistence economies): in contrast to actors in (ideal neoclassical) market economies, maximizing expected utility, they operate in such way as to optimize long-term survival of genetically related groups. This can be seen as a strategy of (maximum) ruin avoidance, played by 'selfish genes'. In the sense of conjectural history the parallelism between risk behaviour of animals and early men may be regarded as the continued existence of principles of natural evolution beyond hominization up to the historical emergence of complex societies where pursuit of surplus production replaced ruin avoidance as the primary orientation in the older subsistence economies.     

Progressive taxes and firm births

Tax reform proposals in the spirit of the “flat tax” model typically aim to reduce three parameters: the average tax burden, the progressivity of the tax schedule, and the complexity of the tax code. We explore the implications of changes in these parameters for entrepreneurial activity, measured by counts of firm births. The Swiss fiscal system offers sufficient intra-national variation in tax codes to allow us to estimate such effects with considerable precision. We find that high average taxes and complicated tax codes depress firm birth rates, while tax progressivity per se promotes firm births. The latter result supports the existence of an insurance effect from progressive corporate income taxes for risk-averse entrepreneurs. However, implied elasticities with respect to the level and complexity of corporate taxes are an order of magnitude larger than elasticities with respect to the progressivity of tax schedules.     

Import-Price Uncertainty, Production Decisions, and Relative Factor Shares

The effects of import-price uncertainty on factor income in Switzerland are estimated. The production-theory approach is used to derive the import demand function from an expected utility maximization problem, treating imports as an input to the technology. The model is also used to test for risk aversion and to assess the impact of uncertainty on the volume of imports and gross output. Evidence is found that, for most years, labor has been relatively more vulnerable to uncertainty than has capital.     

Beyond belief: A benchmark for human resources

Many Human Resource (HR) professionals feel and believe that they have made progress during the 1980s. Unfortunately, without data to benchmark progress, assessments must depend on perception rather than evidence. To move beyond belief towards a national HR database, this article reports research on over 10,000 individuals in 1200 businesses in 91 firms. It establishes a benchmark for HR practices and HR professionals. It also highlights areas where HR professionals may focus attention to become more successful as business partners.     

New strategies and a new paradigm for Shariah-compliant portfolio optimization

In this paper we analyze the effects of different strategies to construct Shariah compatible financial portfolios. The difference between conventional and current Shariah portfolio management is the application of sector screens and financial screens by which the asset universe is reduced. Yet, here different schools of scholars define different screening rules leading to significant differences with respect to compliance, but also with respect to performance. After analyzing this discrepancy we propose several new strategies to apply the inconsistent rule systems and a new paradigm for defining Shariah-compliance. Under this new paradigm compliance is attributed to the portfolio and not to the individual assets of the universe. We report results of an empirical study analyzing the potentials of these strategies and of the paradigm. We can show that under the proposed concepts Shariah-compliant portfolios can be realized which have return and risk profiles comparable to the conventional non-constrained portfolios.
