On the stability of stablecoins
2021
This paper investigates the volatility processes of stablecoins and their potential stochastic interdependencies with Bitcoin volatility. We employ a novel approach to choose the optimal combination for the power law exponent and the minimum value for the volatilities bending the power law. Our results indicate that Bitcoin volatility is well-behaved in a statistical sense with a finite theoretical variance. Surprisingly, the volatilities of stablecoins are statistically unstable and contemporaneously respond to Bitcoin volatility. Also, whereas the volatilities of stablecoins are not Granger-causal for Bitcoin volatility, lagged Bitcoin volatility exhibits Granger-causal effects on the vol…
Collective Behavior of Price Changes of ERC-20 Tokens
2020
We analyze a network constructed from tokens developed on Ethereum platform. We collect a large data set of ERC-20 token prices; the total market capitalization of the token set is 50.2 billion (109) US dollars. The token set includes 541 tokens; each one of them has a market capitalization of 1 million US dollars or more. We construct and analyze the networks based on cross-correlation of tokens’ returns. We find that the degree distributions of the resulting graphs do not follow the power law degree distribution. We cannot find any hierarchical structures nor groupings of ERC-20 tokens in our analysis. peerReviewed
Institutional systems inducing R&D in Amazon- the role of an investor surplus toward stakeholder capitalization
2020
Abstract Amazon demonstrated a conspicuous increase in R&D and became the world's top R&D firm in 2017 with a skyrocketing increase in market capitalization, making it close to being the world's biggest company. Such a remarkable accomplishment can be attributed to Amazon's institutional systems, which orchestrate techno-financing systems that fuse a unique R&D transformation system and a sophisticated financing system centered on the cash conversion cycle (CCC). These institutional systems support and endorse aggressive investment in R&D that incorporates the characteristics of uncertainty, a long lead time, and successive inflows of very large amounts of funding without interruption. Whil…
The value-relevance of social media activity of Finnish listed companies
2022
Purpose The use of social media tools by companies is common, but the links between the use of multiple social media tools by companies and stock price changes are largely unknown. Therefore, this study aims to analyze the value-relevance of social media activities on Facebook (FB), Instagram (IG), LinkedIn (LI), Twitter (TW) and YouTube (YT). Design/methodology/approach Stock market data and hand-picked social media data in this study were collected from Finland, a small language area with consistent International Financial Reporting Standards (IFRS) reporting practices, in the expectation of better comparability and lower noise in the data.This study uses correlation, regression and fact…
Goodwill impairments and the value relevance of goodwill of the small listed companies in Finland
2016
Tutkimuksen tavoitteena on tarkastella, miten liikearvon arvo määräytyy ja onko liikearvo arvorelevanttia. Kohdeyritysten taloudellisten tietojen ja niiden analysoinnin pohjalta on tarkoituksena selvittää, onko liikearvon ja yrityksen markkina-arvon välillä yhteys sekä miten liikearvon määrä on vaihdellut kohdeyritysten taseissa vuosina 2007-2014. Tavoitteena on myös selvittää, miten markkinat suhtautuvat liikearvon arvonalentumiskirjauksiin. Tutkimusmenetelmä on kvantitatiivinen tutkimus, jossa on myös ominaispiirteitä field-tutkimuksesta. Tutkimusaineisto koostuu kirjallisuuden lisäksi kohdeyritysten tilinpäätöstiedoista sekä muusta taloudellisesta informaatiosta, kuten pörssikurssitiedoi…
