Suomen tiedontuotannon regiimi : yksi vai monta?
2021
Poliittisen talouden tutkimuksessa tapahtui 1990-luvulla niin kutsuttu ideakäänne. Viimeisen reilun vuosikymmenen aikana on alettu systemaattisesti tutkia ideoiden tuotantoa ja kanavointia poliittis-taloudelliseen päätöksentekoon. Vertailevan poliittisen talouden tutkimuksen piirissä on kehitetty tiedontuotannon regiimin teoria, joka tarkastelee tiedontuotannon institutionaalisia ja organisatorisia koneistoja, jotka tuottavat ideoita ja asiantuntijatietoa poliittis-taloudellista päätöksentekoa varten. Tämä artikkeli esittelee ja problematisoi tiedontuotannon regiimien tutkimusta. Artikkeli problematisoi tutkimuksen taustaoletusta regiimiin kuuluvien tiedontuottajien muodostaman organisaatio…

Purpose: To study the probabilities and permanence of return to work, inability to work and rehabilitation, and to explore the connection between these life situations and later working after a sev...
Integrated capital shares
2019
In empirical macroeconomics, inter-dependencies between countries are often analysed using cross-country correlations or graphical investigation of time series. This study shows that applying an alternative methodological approach - identification of common unobservable factors and using them as explanatory variables for country-specific time series - indicates a stronger cross-country integration of functional income distributions than the standard methods. The results vary only little between different samples, where both the country and year coverage change. Moreover, the main findings are not sensitive to the way capital depreciation is taken into account. The primary driving factor see…
Speculation and lottery-like demand in cryptocurrency markets
2021
Abstract This is the first paper that explores lottery-like demand in cryptocurrency markets. Since recent research provides evidence that cryptocurrency returns appear to be short-memory processes, we modify Bali, Cakici and Whitelaw’s (2011) and Bali, Brown, Murray, and Tang’s (2017) MAX measure and employ a weekly forecast horizon and daily log-returns from the previous week to calculate the metric for our portfolio sorts. From an econometric point of view, this study proposes statistical tests that are robust to unknown dynamic dependency structures in the cryptocurrency data. Our results show that average raw and risk-adjusted return differences between cryptocurrencies in the lowest a…
Cross-country variation in patience, persistent current account imbalances and the external wealth of nations
2022
This paper is the first to utilize large-scale international surveys on economic preferences to examine the long-run relationships between patience, current accounts and external wealth. We find robust empirical evidence that countries with more patient individuals tend to run persistent current account surpluses, which in turn result in the accumulation of foreign assets. This theoretically plausible but empirically unexplored relationship holds true for euro area current account imbalances, global current account imbalances and net foreign asset positions worldwide. While the existing current account literature concentrates on proximate macroeconomic determinants, this paper’s extension o…
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…
Do commodity assets hedge uncertainties? What we learn from the recent turbulence period?
2022
AbstractThis study analyses the impact of different uncertainties on commodity markets to assess commodity markets' hedging or safe-haven properties. Using time-varying dynamic conditional correlation and wavelet-based Quantile-on-Quantile regression models, our findings show that, both before and during the COVID-19 crisis, soybeans and clean energy stocks offer strong safe-haven opportunities against cryptocurrency price uncertainty and geopolitical risks (GPR). Soybean markets weakly hedge cryptocurrency policy uncertainty, US economic policy uncertainty, and crude oil volatility. In addition, GSCI commodity and crude oil also offer a weak safe-haven property against cryptocurrency uncer…

Thomas Hobbes ja pelon taloustiede
2013
Thomas Hobbesia (1588-1679) pidetään usein yhtenä ”kapitalismin isistä”. Näkökulma on kuitenkin sinänsä ongelmallinen, että Hobbes ei juurikaan kirjoittanut pääomista tai tuotannosta. Hänen poliittinen ajattelunsa oli vastakkaista Englannin nousevan porvariston pyrkimyksille toteuttaa vero- ja kauppavapaus. Hobbes piti aikansa Alankomaita huonona esimerkkinä pääoman ja vapauden liitosta.Kysymys omistuksesta löytyy kuitenkin Hobbesin yhteiskuntateorian perustasta. Kuuluisassa ”luonnontilassa” ei voi Hobbesin mukaan olla omistusta, koska vain oikeusjärjestelmä yhdessä väkivallan monopolin kanssa kykenee takaamaan sen. Hobbes kannustaa ihmisiä tuottavaan elämään ja näkee valtion tehtävänä sell…
