In this paper, we (1) examine the interactions of financial variables and the macroeconomy within the block-restriction vector autoregression model and (2) evaluate to what extent the financial variables improve the forecasts of GDP growth and inflation. For this reason, various financial variables are examined, including those unexplored in previous literature, such as the share of liquid assets in the banking industry and the loan loss provision rate. Our results suggest that financial variables have a systematic and statistically significant effect on macroeconomic fluctuations. In terms of forecast evaluation, financial variables in general seem to improve the forecast of macroeconomic variables, but the predictive performance of individual financial variables varies over time, even though it strengthens during the 2008?C2009 crisis. The results give some support for the risk-taking channel of monetary policy, as the level of the monetary policy rate is positively associated with the loan loss provision rate of commercial banks. Finally, a more stable financial system is found to contribute to faster economic growth. 相似文献

Gnaeus Julius Agricola (40-93 AD) is a man for our times. Facing the capriciousness of imperial power, he, a successful provincial Roman governor, chose to withdraw from public administration. Yet, by protecting his family, Agricola did not shirk politics. On the contrary, he retreated to the founding cell of any polity, the family, which buttresses and at the same time limits the state. By doing so, Agricola reached greatness despite living under bad emperors. 相似文献

Abstract: The research is focused on the detection and transfer of iron traces left by iron items on clothing and human skin. The method is based on the formation of colored complexes between ferrous ions and five synthesized, mostly new triazines. Iron traces originally were left by iron rings on slightly wetted (artificial sweat) cotton fabrics and subsequently transferred to a separate textile substrate. Prior to the use of trazines the contact spots were treated with a new inorganic reducing agent (Sn2+) to reduce Fe3+ to Fe2+. The method is sensitive to detect iron traces on wetted canvas after 10 min contact with iron items. More spectacular results were obtained for traces left on human palm even after very short contact (10 sec). The new iron‐trace‐transfer method eliminated the contact of triazines solutions with human skin. Transmission visible spectra of Fe(II)–triazine complexes were determined. 相似文献

After the collapse of the Soviet Union the newly independent Russia had to redefine its relations with the outside world. In order to establish new relationships with both new and traditional cooperation partners, the country's leadership had to define the main strategic objectives, identify the main interests and threats to Russia's security and propose new ways of coping with the challenges the vast country confronted. The first years of independence were marked by a power struggle between various parts of the political elite, which delayed the process of defining the country's strategic goals in the field of national security. In December 1997, the Concept of National Security of the Russian Federation was published, and in January 2000 a new version was made public. This brief article is a comparative study of the concepts of national security embodied in the two documents, focusing on Russia's relations with the outside world and use of nuclear deterrence as a means to solve security and status dilemmas. 相似文献

The United States has had, and will continue to have, a difficult time gathering allies because of the supremacy it enjoys. States support the United States not because they share a common objective, but because they want to benefit politically, economically, and strategically from being associated with Washington. In other words, the United States has allies not because of the objective it tries to achieve but because of what it can offer to them. Such alliances are fickle and last only as long as the benefits allies derive from Washington outweigh the costs. For the United States, managing this situation requires three skills: first, the continued ability to offer benefits to potential allies; second, diplomatic dexterity to manage mostly bilateral alliances; and third, the strategic flexibility required in order to be able to change swiftly from one ally to another. 相似文献

The aim of the article is to present the results of road tests of original and retreaded tyres, analysed in the aspect of vehicle active safety. The tests covered emergency braking, steady-state circular tests and severe lane-change manoeuvre. The tests were performed in summer and winter conditions. Original Michelin tyres and Michelin tyres retreaded with summer and winter rubber compounds were used. The results of the tests proved that vehicle active safety is affected by retreaded tyres. The differences between braking deceleration of a car with original tyres and braking deceleration of a car with retreaded tyres confirmed the necessity of performing braking tests on the place of accident with the set of tyres with which the vehicle participating in the accident was equipped. 相似文献
