When legacy carriers converge with low-cost carriers: Exploring the fusion of European airline business models through a case-based analysis

The paper makes uses of cognitive mappings developed from personal interviews with a number of European airline executives to examine the differences in managerial attitudes of low-cost and transitional carriers. In particular it explores the extent to which there is a convergence of views regarding the ways various airline models will develop in the future.     

A tale of two Italian cities: brand-level milk demand and price competition

We apply the BLP random coefficient logit model demand model to fluid milk sales data from two north-south Italian cities: Turin and Naples. By virtue of their location and socioeconomic differences, these cities provide a natural experiment for contrasting consumer choices and retail market power related to milk physical and marketing characteristics. Results reveal that, regardless of location, consumers negatively value price increases, fat content and ultra-high temperature (UHT) treatment. However, location matters with respect to brand and type of milk purchased. While in Turin (the higher-income region) demand for the leading manufacturers’ brands is the most price inelastic, in Naples consumers have the lowest price elasticities in case of cheaper milk, often small manufacturer or private label brands. Unlike previous studies, we do not find price elasticities for private labels to be consistently lower (or markups to be higher) compared to manufacturer brands, indicating that private labels have reached maturity in these markets. Further, while demand for fresh milk is more price inelastic in Turin, it is more inelastic for UHT milk in Naples. Likewise, markups and Lerner indexes are higher for fresh milk in Turin and for UHT in Naples corresponding to the more inelastic demands under Bertrand price competition.     

A round of dancing and then one more: embedding intuition in the ballet of entrepreneurial decision making

The dance metaphor allows us to figuratively depict entrepreneurial decision making processes. Being conventionally conceived of as a sequence of purposeful behaviors rooted in a rational cognition process, entrepreneurial decision making can be featured as a ‘ballet’. This interpretation puts in the background the improvisational nature of decision making, which revokes ‘lindy hop’ as a dance style. The article intends to illuminate the role of intuition, highlighting its overlap with rationality in the entrepreneurial decision making dance. For this purpose, a bibliometric analysis followed by an interpretive literature review advances a comprehensive report of 66 peer-reviewed journal articles published from 1995 to 2019, constructing evidence on the nature of entrepreneurial decision making and on the interplay between intuition and rationality. Literature is categorized in five clusters, which are reciprocally intertwined. Firstly, intuition is unconsciously used as a strategy to deal with the uncertainty that inherently affects entrepreneurial ventures. Secondly, intuition is rooted in the entrepreneurs’ impulsivity, that echoes the role of emotions in decision making. Thirdly, the merge of rationality and intuition improves the entrepreneurs’ ability to keep up with the erratic rhythm of the decision making dance. Fourthly, the mix of intuition and rationality serves as a catalyst of entrepreneurs’ ability to thrive in complex and unpredictable environments. Fifthly, intuition generates drawbacks on entrepreneurs’ meta-cognitive knowledge, which should be carefully recognized. Embracing the dance metaphor, intuition turns out to be crucial to make entrepreneurs able to fill in the gap between rationality and uncertainty.

     

Spectrum value

Radio spectrum is a scarce resource; understanding its economic value is one piece of information needed to manage it efficiently. Estimating the value of radio spectrum, however, creates significant challenges not found in valuing some other assets. Spectrum is somewhat of a special case; market transactions provide a basis for valuation, but almost always require significant adjustments. Some adjustments are best made using discounted cash flow (DCF) analysis or econometric evidence. A review of past work on spectrum valuations suggests that focusing on a single valuation technique leaves critical information about spectrum value unused.     

Modeling stock pinning

This paper investigates the effect of hedging strategies on the so-called pinning effect, i.e. the tendency of stock's prices to close near the strike price of heavily traded options as the expiration date nears. In the paper we extend the analysis of Avellaneda and Lipkin, who propose an explanation of stock pinning in terms of delta hedging strategies for long option positions. We adopt a model introduced by Frey and Stremme and show that, under the original assumptions of the model, pinning is driven by two effects: a hedging-dependent drift term that pushes the stock price toward the strike price and a hedging-dependent volatility term that constrains the stock price near the strike as it approaches it. Finally, we show that pinning can be generated by simulating trading in a double auction market. Pinning in the microstructure model is consistent with the Frey and Stremme model when both discrete hedging and stochastic impact are taken into account.     

The near-death experience of the celtic tiger

This article narrates Ireland’s recent odyssey from the pride and envy of Europe to kneeling supplicant through the eyes of an econometric model of the government bond market. The exercise suggests that, in essence, two developments triggered and propelled Ireland’s drift towards sovereign default: first, the global financial crisis that drove Ireland into a severe recession with collapsing tax revenues and increasing unemployment; second, a gap between the post-2007 increase in sovereign default risk that can actually be linked to macroeconomic fundamentals and the much bigger increase in perceived risk reflected by high interest rates and communicated by the massive downgrades of Ireland’s sovereign debt rating.
