We introduce a pro-cyclical endogenous utilization rate of physical capital stock into a real business cycle model augmented with a government sector in detail. We calibrate the model to Bulgarian data for the period following the introduction of the currency board arrangement (1999–2016). We investigate the quantitative importance of the endogenous depreciation rate and the capital utilization mechanism working through the use of energy for cyclical fluctuations in Bulgaria. In particular, a positive shock to energy prices in the model works like a negative technological shock. Allowing for variations in factor utilization and the presence of energy as a factor of production improves the model performance against data, and in addition this extended setup dominates the standard RBC model framework with constant depreciation and a fixed utilization rate of physical capital (e.g., Vasilev (2009)).

To understand historical changes in energy performance of economy or specific sector, it is useful to evaluate the driving forces underlying these changes. Structural decomposition analysis allows identifying the impact of the external factors, such as technological, demand, and demographic effects on the fluctuations of the total energy use, CO2 emissions, and other socio-economic indicators. This study applies methods of structural decomposition analysis to determine relative prominence of diverse sources of changes in the energy use in the Polish economy and its main sectors between 2000-2015. The author presents the methodology of decomposition into different explanatory factors, among which energy savings based on top-down indicators, which allows showing additionally what the role of energy efficiency improvements is at the level of the different sub-sectors and end-uses. The analysis is extended into comparison to European statistics in the context of implementation and monitoring of the UE indicative energy targets.

Celem lepszego zrozumienia historycznych zmian charakterystyki energetycznej gospodarki i poszczególnych sektorów, konieczne jest określenie sił napędowych tych tendencji. Metoda ta pozwala zidentyfikować wpływ czynników zewnętrznych, takich jak zmiany technologiczne, popytowe i demograficzne, na wahania całkowitego zużycia energii, emisji CO2 oraz innych wskaźników społeczno-gospodarczych. W badaniu wykorzystano metodę dekompozycji strukturalnej do określenia relatywnego znaczenia różnorodnych źródeł zmian w zużyciu energii w polskiej gospodarce i jej głównych sektorach w latach 2000-2015. W artykule przedstawiono metodologię dekompozycji na różne czynniki objaśniające, która uwzględnia oszczędności energii oparte na wskaźnikach typu „top-down”, co pozwoliło wskazać, jaka była rola poprawy efektywności energetycznej w zmianach zużycia energii na poziomie różnych podsektorów i użytkowników końcowych. Analiza została poszerzona o zestawienie porównawcze ze statystykami europejskimi w kontekście wdrażania i monitorowania celów energetycznych UE.

There’s a strong link between the production of biofuels and energy crops. The first of these activities may contribute to the appearance of new products in agriculture, besides giving a boost to activities such as provision of services and aiding in the diversification of economic activities in rural areas. Farmers’ final decision to include energy crops into or exclude them from their productive alternatives depends on various factors of a different nature (political, legal, technical, economic or socio-cultural). This paper analyzes the socio-economic aspects related to the introduction of oil-seeds (sunflower and rape seed) as energy crops in one of the most important agricultural regions in Spain (Castile and Leon). Thus, using RRA (Rural Rapid Appraisal) and the Economic Accounts for Agriculture (EAA), the study provides an evaluation of the main economic accounts of these crops and an idea of their profitability, impact on the level of employment and environmental consequences.
