In January 1992, Kazakhstan initiated a reform programme to move towards market-determined prices. The price liberalization process was characterized by large relative price shifts and an increase in the overall price level towards those observed in market economies. The paper shows how the piecemeal manner in which prices were liberalized resulted in strong relative price variability over a prolonged period of time, against a background of high inflation. Convergence towards international relative and absolute price levels has progressed but is not complete, with prices for energy and services in particular still below market economy levels. 相似文献

We consider the M/M/1-queue and derive an explicit expression for the joint distribution of the number of arrivals and the number of departures in [0, t), given the number of customers initially present. The derivation is almost purely combinatorial, it avoids the use of generating functions, and immediately yields a simple probabilistic interpretation of the result. 相似文献

This paper proposes a new measure of contagion, based on the frequency analysis of causality developed recently by Breitung and Candelon [Breitung, J., Candelon, B. 2006. Testing for short and long-run causality: a frequency domain approach, Journal of Econometrics, 12, 363–378.]. This approach handles several of the statistical problems identified in the literature. It also permits clear differentiation between temporary and permanent shifts in cross-market linkages: the first case is contagion while the second one is simply a measure of interdependence among markets. With this new approach, we examine the “Tequila” and Asian crises and find evidence of contagion for both. During the Asian crisis, higher interdependence has also contributed to the diffusion of the crisis in Asia. 相似文献

To model the evolution of strategic intelligence, player types are drawn from a hierarchy of "smartness" analogous to the levels of iterated rationalizability. Nonrationalizable strategies die out, but when higher levels of smartness incur maintenance costs, being right is always as good as being smart. Moreover, if a manifest way to play emerges, then dumb players never die out, while smarter players with positive maintenance costs vanish. These results call to question the standard game-theoretic assumption of super-intelligent players. Journal of Economic Literature Classification Numbers: B40, C70, C72, C73. 相似文献

For allocation problems with one or more items, the well-known Vickrey–Clarke–Groves (VCG) mechanism (aka Clarke mechanism, Generalized Vickrey Auction) is efficient, strategy-proof, individually rational, and does not incur a deficit. However, it is not (strongly) budget balanced: generally, the agents' payments will sum to more than 0. We study mechanisms that redistribute some of the VCG payments back to the agents, while maintaining the desirable properties of the VCG mechanism. Our objective is to come as close to budget balance as possible in the worst case. For auctions with multiple indistinguishable units in which marginal values are nonincreasing, we derive a mechanism that is optimal in this sense. We also derive an optimal mechanism for the case where we drop the non-deficit requirement. Finally, we show that if marginal values are not required to be nonincreasing, then the original VCG mechanism is worst-case optimal. 相似文献

In previous periods when agricultural production was large relative to demand in North America, supply control through limitations in production and markets has been used. Large cropfalls and mammoth international purchases by the USSR during the early 1970s depleted North American grain stocks and caused major supply control programs to vanish. With more favorable worldwide weather, however, grain production and carryover have increased to levels where farmers may demand supply and market controls to improve prices and income. In contrast to conventional models, we make a quantitative analysis for the United States to three tax policies which might be used to restrain production and improve prices and farm income. All tax alternatives do so if the taxes collected by the government are returned to farmers. The tax alternatives examined include a tax on inputs, a gross sales tax, and a tax-in-kind similar to a share rent. The tax policies are applied through an econometric simulation model. Certain limitations of the tax policies are explained. Aux époques antérieures, lorsque la production agricole était grande compareée à la demande dans l'Amérique du Nord, on a contrôlé les stocks de réserve par moyen de limitations de production et de vente. Les récoltes inférieures et les énormes achats par l'URSS pendant la premiére partie des années 70 ont diminué les réserves des céréales de l'Amérique du Nord, ce qui a rendu superflus les programmes majeurs de contrôle. Toutefois, un climat global favorable a augmenté la production et l'accumulation jusqu'au point oú les agriculteurs peuvent considérer nécessaires des contrôles sur la production et la vente afin d'améliorer les prix et leurs revenus. Faisant contraste avec les modéles conventionnels, nous présentons une analyse quantitative pour les Etats-Unis de trois systémes d'impôts qui pourraient etre appliqués pour diminuer la production et pour améliorer les prix et les revenus agricoles. Tous les trois systémes sont effectifs à ce but, pourvu que les impôts perçus par le gouvernement soient rendus aux producteurs. Les alternatifs examinés comprennent un impôt sur les frais de production, un impôt en gros sur les ventes et un systéme d'impôts payables par une quantité des céréales produites, semblable au métayage. Les systémes sont appliqués par moyen d'un modéle de simulation économétrique. Certaines limitations des systémes sont presentées. 相似文献

This article presents a medium-term forecast of the development of the Russian nanoindustry, taking into account the assumed transition of the industry from the formation stage to the investment growth stage. Problems associated with the estimated output volumes of products in the Russian nanoindustry are considered, since the trends recorded in the primary statistical data are very far from reflecting the real situation due to the imperfection of the system of statistics of nano-containing products, as well as a reduction of state funding and a decline in the intensity of research in the industry. It is concluded that a full-fledged industry has not been yet completely formed in Russia and it actually exists only as a statistical phenomenon; in addition, the project really set different objectives from the declared creation of a breakthrough high-technology branch. 相似文献
