The heat capacities of fenpropathrin in the temperature range from 80 to 400 K were measured with a precise automatic adiabatic calorimeter. The fenpropathrin sample was prepared with the purity of 0.9916 mole fraction. A solid—liquid fusion phase transition was observed in the experimental temperature range. The melting point, Tm, enthalpy and entropy of fusion,
fusSm, were determined to be 322.48±0.01 K, 18.57±0.29 kJ mol–1 and 57.59±1.01 J mol–1 K–1, respectively. The thermodynamic functions of fenpropathrin, H(T)—H(298.15), S(T)—S(298.15) and G(T)—G(298.15), were reported with a temperature interval of 5 K. The TG analysis under the heating rate of 10 K min–1 confirmed that the thermal decomposition of the sample starts at ca. 450 K and terminates at ca. 575 K. The maximum decomposition rate was obtained at 558 K. The purity of the sample was determined by a fractional melting method.

The correct modelling of long- and short-term seasonality is a very interesting issue. The choice between the deterministic and stochastic modelling of trend and seasonality and their implications are as relevant as the case of deterministic and stochastic trends itself. The study considers the special case when the stochastic trend and seasonality do not evolve independently and the usual differencing filters do not apply. The results are applied to the day-ahead (spot) trading data of some main European energy exchanges (power and natural gas).
This study focuses on the level of interdependence across the Central and Eastern European (CEE) foreign exchange markets (Hungary, Poland, the Czech Republic, Romania and Croatia) from September 2008 to September 2017, using the return spillover measure proposed by Diebold and Yilmaz (2009; 2012). We mainly find a bidirectional volatility spillover among these assets and the cross-market linkages in the CEE region have become stronger over time. Furthermore, the Czech exchange market has a significant influence on the rest of the foreign exchange markets. The total spillover remained very high over the periods 2010–2012 and 2015–2017, despite the noteworthy fluctuations in other periods. These results would also be useful for portfolio managers, policy makers and speculative traders to develop exploitable strategies, by providing knowledge of the transmission mechanisms of the volatility of foreign exchange markets. The results may support the distribution of assets in a financial portfolio, especially after financial integration.

This paper empirically explores the validity of the Kaldorian insights into economic growth and development. In doing so, we examine the three laws outlined in Kaldor’s analysis and test their relevance to the Greek economy for the period 1970–2006. We employ the ARDL method to analyse the long-run and short-run relationships among the variables. The empirical results confirm Kaldor’s proposition about the importance of the demand side of the economy and thus provide the necessary theoretical and empirical ground for innovative economic policies in these difficult times for Greece.
This paper provides an empirical analysis of the relationship between the labour income share and financialisation, as well as other related variables in Portugal from 1978 to 2012. We estimate an equation for the labour share that includes standard variables (technological progress, globalisation, education and business cycle) and variables to capture the effect of financialisation. We formulate the hypothesis that the financialisation process may lead to a rise in the inequality of functional income distribution through three channels: the change in the sectoral composition of the economy (due to both the increase in the weight of financial activity and the decrease in government activity), the diffusion of shareholder value governance practices and the weakening of trade unions. Our results show that the financialisation process has an indirect long-term effect on the labour share through its impact on government activity and trade union density. The paper also finds evidence supporting the traditional explanations for functional income distribution, namely globalisation, education and business cycle.
This paper proposes a new measure of central bank credibility — the credibility index calculated on the basis of the key determinants of central bank credibility. The index is compiled for 9 countries: the Czech Republic, Hungary, Slovakia, Poland, Chile, Brazil, Turkey, United Kingdom and Sweden , for the years 1999–2007. The results are cross-checked with other credibility measures based on inflation expectations of two groups of economic agents. The analysis demonstrates that the credibility index may be considered a relevant and consistent credibility measure.
We test whether the discouraged worker or added worker effect prevails in the Polish labour market. The discouraged worker effect implies that the participation rate is procyclical with respect to the GDP and countercyclical with respect to the unemployment rate. The added worker effect yields contrary findings. We analyse the period 1994–2014 with quarterly data. We focus on the working age population, both males and females. We apply a range of methods to obtain robust results, some of which have never been employed to resolve this problem. They include ad hoc filtration, spectral analysis, unobserved component model, time-varying parameter model, and frequency domain regression. The results indicate that the added worker effect prevails in most of the business cycle frequencies. It is significant and varies over time. It is true for both males and females. It is considerably stronger in contractions than in expansions. In low business cycle frequencies, the discouraged worker effect prevails. Although the last case is rare, it proves the heterogeneity of labour force behaviour over the business cycle.
Looking at almost forty years’ data the strong preference of consumption and housing investment to financial savings is an observable characteristic of Hungarian households’ long-term behaviour. This observation seems to be valid despite the substantial changes in the institutional system. Credit supply has played an important role in this. Households increase their consumption and housing expenditures by taking advantage of lending opportunities. The increased credit supply is coupled with a low financial savings rate. This in not unique in the European countries, however, it may lead to a riskier macroeconomic path for Hungary.

This study investigates the impact of the selected financial development proxies and foreign direct investment (FDI) on the growth in the case of Turkey, using annual data for the 1960–2011 period. The second-generation econometric procedure has been applied for the first time to the Turkish data with this respect. Unit root tests by Carrion-i-Silvestre et al. (2009) assume that real income, financial development proxies, and FDI are non-stationary at levels, but become stationary at first differences through multiple structural breaks. Cointegration results by Maki (2012) confirm the existence of a long-term equilibrium relationship between real income growth, financial development, and FDI, again through multiple structural breaks. Finally, this paper confirms that financial development and FDI are long-term drivers of real income, which enable it to react to its long-term path significantly.
