The Use of the Twitter in Public Benefit Organisations in Poland: How Communicative Function of Tweets Translates Into Audience Reaction?

numbers. 3.2 Data In order to carry out the relevant analyses, it was necessary to complete the tweets database. In order to eliminate the problem of randomness (for each organisation, there may be events that could cause unusually high activity for the organisation on Twitter for a short time) a sufficiently long period was used for the analysis. In the range from 15 July to 12 October 2017 (i.e. 90 days), each day of the week was randomly selected twice (i.e. two Mondays, two Tuesdays, etc.). If the selected testing days were immediately following one another

On the Relation Between Health and Income: A Cross-Country Analysis

equilibrium. When cross-country differences are concerned, the countries with a greater propensity in both human and physical capital will be relatively richer given that this set of countries is experiencing the same rate of labour-augmenting technological process. Mankiw, Romer and Weil (1992) in addition tested the Solow model empirically as well. They found that a significant part of the income differences across countries can be explained by the differences in human and physical capital investment behavior. Then, the immediate implication is that attention should be

Dynamic Fiscal Solvency with Consumption and Capital Taxes

-term equilibrium, solving dynamic optimisation problem with continuous time. In other words, we are looking for optimal long-term tax policy of the government aiming to sustain fiscal solvency, contingent on the values of chosen parameters. We assume capital income to be partially or fully shifted abroad as a consequence of tax avoidance strategies of economic agents. We believe that this better reflects the limited mobility of physical capital and the treat of possible income shifting. For example, one can expect the latter to intensify during an insolvency crisis when fast

External Costs of Opencast Brown Coal Mining in Agriculture and Agri-Food Industry (on the Example of Wielkopolska)

also changed, by which one means to multiply one type of wealth that does not take place at the expense of others. The richness of the nation consists of, inter alia, natural wealth and indirectly the richness of nature, anthropogenic material and financial wealth, physical and intellectual human wealth as well as social, cultural and institutional richness ( Poskrobko 2011 , 9). Therefore, taking into account external effects, especially in large projects interfering with the environment is of key importance for achieving long-term social and ecological goals. The

What Determines Export Performances in High‑tech Industries

rest of the world in 1999−2011. Together with the standard gravity variables, our model controls for the technology gap and the difference in factor endowments of the trade partners. Following Santos Silva and Tenreyro (2006) , we estimate the model by PPML for the EU-15 and V4 separately. The estimation results show that while for the EU-15, human capital accumulation is statistically significant and export flows increase with similarity in physical capital accumulation of the trade partner; for V4, instead of similarity, the difference in physical capital stock

On the other hand, the Black-Scholes model is still widely used not only as a benchmark in comparative studies testing various option pricing models, but also among the market participants. Christoffersen and Jacobs (2004) show that much of its appeal is related to the treatment of volatility – the only parameter of the Black-Scholes model, however, is not
