Poor nutritional quality of primary producers and zooplankton driven by eutrophication is mitigated at upper trophic levels

2022

Eutrophication and rising water temperature in freshwaters may increase the total production of a lake while simultaneously reducing the nutritional quality of food web components. We evaluated how cyanobacteria blooms, driven by agricultural eutrophication (in eutrophic Lake Köyliöjärvi) or global warming (in mesotrophic Lake Pyhäjärvi), influence the biomass and structure of phytoplankton, zooplankton, and fish communities. In terms of the nutritional value of food web components, we evaluated changes in the ω-3 and ω-6 polyunsaturated fatty acids (PUFA) of phytoplankton and consumers at different trophic levels. Meanwhile, the lakes did not differ in their biomasses of phytoplankton, zoo…

Argentina’s Economic Development and Life Satisfaction Revisited – 1984–2012

2014

At the end of 1983, Argentina returned to democracy. Between 1983 and 2012, Argentina brought better economic and development results as wells as an improvement in the levels of happiness and life satisfaction. Although the macroeconomic cycle was characterized by high volatility, the country GDP per capita was 74 % higher in 2012 compared to 1983, implying an average annual growth rate of 1.9 %, much higher than the average Latin American country. Poverty and income distribution as well as health and education ones notably improved after time intervals of decadence.

New paradigm of ICT productivity – Increasing role of un-captured GDP and growing anger of consumers

2015

Abstract The dramatic advancement of the Internet has led all nations to an information communication technology (ICT) driven development trajectory. This trajectory has resulted in bi-polarization between ICT growing economies and ICT advanced economies. While the former enjoys a virtuous cycle between ICT advancement and productivity increase, the later has fallen into a trap of a vicious cycle between ICT advancement and productivity decrease. This paper identifies that this trap can be attributed to the two-faced nature of ICT in which advancement of ICT contributes to price increases due to functionality development while dramatic advancement of the Internet has resulted in price decre…

Stock market and exchange rate information in the Taylor rule : Evidence from OECD countries

2017

We analyze the effects of stock market and exchange rate information in a forward-looking Taylor rule for monthly data from 14 OECD countries during the years 1999–2016. Especially the stock market information in the form of dividend but also the currency market information in the form of real exchange rate are revealed to be relevant in Taylor rule for many of the countries examined by helping to strengthen the role of inflation and real economic activity deviations in the policy rule. In many cases the rule also seems to be opportunistic, i.e., the inflation target has been time-varying. peerReviewed

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…

Happiness at work in knowledge-intensive contexts: Opening the research agenda

2018

In today's business environment, management of knowledge-intensive workers has become one of the most challenging elements to consider. To sustain a company's competitive advantage, highly skilled workers who are perfectly aligned and motivated in the organization are essential. However, happiness becomes essential for these type of employees. Happiness at work is a research topic that is growing in importance among academics, but requires further attention. Through a narrative synthesis method, we review, clarify and suggest future research lines to develop research on happiness at work in knowledge-intensive contexts. JEL classification: J28, I310, M120, Keywords: Happiness at work, Knowl…

Competition and innovation with selective exit: an inverted-U shape relationship?

2017

This paper extends the approach of the inverted-U relationship between competition and innovation at the industry level introduced by Aghion and coauthors. We use data of Spanish manufacturing firms from the Survey of Business Strategies (ESEE) spanning 1990–2006, as well as external information on patents from the European Patent Office and US Patent Office. Instead of an inverted-U shape, we obtain an unambiguous positive relationship between competition and patents. To explain this positive relationship, we modify their theoretical model to introduce the possibility of inefficient firms facing the threat of exit when competition intensifies. The modified model may explain both a positive…

Risk assessment and profit sharing in business networks

2011

Abstract Nowadays network is the preferred governance form to conduct economic transactions. Network solution allows to reach flexibility maintaining cost and quality level. Since network concept refers to a great variety of organizational hybrids it is possible to choose the one that fits better market requirements. The new trends in inter-organization relationships push towards network solutions: companies are interested in relationships with partners and customers to overcome resource dependence, to enter too risky market or simply differentiate their business portfolio. The proposed research focuses on the network concept aiming at highlighting threats and opportunities to investigate t…

Keep the faith in banking : New evidence for the effects of negative interest rates based on the case of Finnish cooperative banks

2021

This paper analyses the profitability of Finnish cooperative banks during the period of negative nominal interest rates. Contrary to expectations, the continuous decline in money market interest rates between 2009 and 2014, and the following negative rate era, did not have adverse effects on the profitability of banks at the beginning of negative interest rate period. Based on especially using a risk-adjusted measure for bank profitability, these results contrast with previous findings. In our findings, the increasing wholesale funding (WSF) ratio seems to be an important factor. However, after 2017 the banks have not been able to improve especially their risk-adjusted profitability so stro…
