How Much Are We Willing To Lose in Cyberspace? On the Tail Risk of Scam in the Market for Initial Coin Offerings
2020
From an entrepreneurial perspective, Initial Coin Offering (ICO) has become an alternative way for attaining funding for business projects using the new evolving digital financial market for tokens. Unfortunately, the majority of all ICOs are subject to scam which casts doubt on this new innovative tool for acquiring funding. Using a unique intensively hand-collected data set covering more than 5000 ICOs which have been launched in the August 2014–December 2019 period, we could identify 1014 ICOs exhibiting data on raised funding whereof 576 turned out to be scams projects. The cumulative losses due to scam in the ICO market correspond to $10.12 billion which is 66% of our identified overal…
Contagion of Uncertainty: Transmission of Risk from the Cryptocurrency Market to the Foreign Exchange Market
2019
Earlier research documented that cryptocurrencies, including Bitcoin, have experienced dramatic fluctuations in both market capitalization and market share in recent years. Unsurprisingly, Bitcoin returns exhibit higher volatility than traditional G-10 currencies. Our paper extends earlier research and investigates the potential impact of news originating from the Bitcoin market. Confirming earlier studies, we find that Bitcoin exhibits dramatically higher volatility than the dollar factor. Surprisingly, our findings indicate that only hacking incidents that occur in the Bitcoin market result in high levels of co-movement in the risk of both markets the cryptocurrency and the G-10 currency …
Trading activity and price impact in parallel markets: SETS vs. off-book market at the London Stock Exchange
2011
We empirically study the trading activity in the electronic on-book segment and in the dealership off-book segment of the London Stock Exchange, investigating separately the trading of active market members and of other market participants which are non-members. We find that (i) the volume distribution of off-book transactions has a significantly fatter tail than the one of on-book transactions, (ii) groups of members and non-members can be classified in categories according to their trading profile (iii) there is a strong anticorrelation between the daily inventory variation of a market member due to the on-book market transactions and inventory variation due to the off-book market transac…
Revisión del desarrollo de la orientación sociolaboral como política activa de empleo= A purpose of guidance active labour employment as a policy
2014
ABSTRACT The purpose of this article is threefold: 1st) to analyse the contextual framework for the development of social and occupational guidance, 2nd) to describe the career guidance sub-systems and their interaction, 3rd) to review the meaning of labour insertion as an impact factor that evaluates the quality of the service, and 4th) to show perverse effects of guidance as an active employment policy. The methodology used is based on the compilation and analysis of secondary sources and it evolves from the study of the bibliography and regulation, as well as of specific current research related to career guidance in Spain. As a result of this research work, the fragmentation of the gui…
A hybrid approach to international market selection: The case of impact investing organizations
2020
Abstract Social enterprises are hybrid organizations that concurrently pursue social and economic goals and hence are mid-way between conventional capitalistic firms and non-profit organizations. Many social enterprises are becoming international; delivering services across borders. With the objective of understanding the internationalization of these unconventional organizations, this paper examines their international market selection decision based on host countries’ macroeconomic conditions. Generally, we hypothesize that the international market selection decision of social enterprises is tied to their hybridity, an overarching characteristic that sets them apart from other types of or…
Training strategic thinking: Experimental evidence
2014
Abstract Strategic behavior is crucial for strong firm performance, especially in competitive environments. Thus, designing a good strategy is a key issue for firms. Designing a strategy requires a combination of strategic thinking—which involves analyzing a firm's strategic environment, defining a vision of its future, and devising new ideas to out-think competitors – and strategic planning – which implies using these ideas to formulate a business plan. Although many firms excel at strategic planning, few devote enough resources to strategic thinking, which results in strategic insanity (i.e., firms repeatedly applying the same strategies with the expectation of different outcomes). To fos…
Nickel on Mars: Constraints on meteoritic material at the surface
2006
[1] Impact craters and the discovery of meteorites on Mars indicate clearly that there is meteoritic material at the Martian surface. The Alpha Particle X-ray Spectrometers (APXS) on board the Mars Exploration Rovers measure the elemental chemistry of Martian samples, enabling an assessment of the magnitude of the meteoritic contribution. Nickel, an element that is greatly enhanced in meteoritic material relative to samples of the Martian crust, is directly detected by the APXS and is observed to be geochemically mobile at the Martian surface. Correlations between nickel and other measured elements are used to constrain the quantity of meteoritic material present in Martian soil and sedimen…
Search for magnetic minerals in Martian rocks: Overview of the Rock Abrasion Tool (RAT) magnet investigation on Spirit and Opportunity
2008
[1] The Rock Abrasion Tool (RAT) on board the Mars Exploration Rovers (MER) is a grinding tool designed to remove dust coatings and/or weathering rinds from rocks and expose fresh rock material. Four magnets of different strengths that are built into the structure of the RAT have been attracting substantial amounts of magnetic material during RAT activities from rocks throughout both rover missions. The RAT magnet experiment as performed on Spirit demonstrates the presence of a strongly ferrimagnetic phase in Gusev crater rocks, which based on Mossbauer and visible/near-infrared reflectance spectra is interpreted as magnetite. The amount of abraded rock material adhering to the magnets vari…
Identification of carbonate-rich outcrops on Mars by the Spirit rover.
2010
Ancient Carbonate Minerals on Mars The historical presence of liquid water on Mars together with a CO 2 -rich atmosphere should have resulted in the accumulation of large deposits of carbonate minerals. Yet, evidence for the presence of carbonates on the surface of Mars has been scarce. Using data collected by the Mars Exploration Rover, Spirit, Morris et al. (p. 421 , published online 3 June; see the Perspective by Harvey ) now present evidence for carbonate-rich outcrops in the Comanche outcrops within the Gusev crater. The carbonate is a major outcrop component and may have formed in the Noachian era (∼4 billion years ago) by precipitation from hydrothermal solutions that passed through …
