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

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

Some financial stress events lead to macroeconomic downturns, while others appear to be isolated to financial markets. We identify financial stress regimes using a model that explicitly links financial variables to macro‐economic outcomes. The stress regimes are identified using an unbalanced panel of financial variables with an embedded method for variable selection. Our identified stress regimes are associated with corporate credit tightening and with NBER recessions. An exogenous deterioration in our financial conditions index has strong negative effects in economic activity, and negative amplification effects on inflation in the stress regime. These results are obtained with a novel factor‐augmented vector autoregressive model with smooth‐transition regimes (FASTVAR). 相似文献

ABSTRACT This study examines the four commonly tested hypotheses in hydroelectricity consumption – economic growth literature for 12 Asian countries. Our results from a recently developed hidden cointegration technique uncover rich and significant relationships between negative and positive components of the variables under consideration. In particular, we find evidence to support the neutrality hypothesis in five countries (Bangladesh, Indonesia, Pakistan, Philippines, and Thailand), the growth hypothesis in four countries (India, Japan, South Korea and Taiwan), and both growth and conservation hypotheses in three countries (China, Malaysia, and New Zealand). These findings suggest that appropriate economic policies should be elaborated on the basis of the country’s specific hydroelectricity consumption–growth nexus. Finally, our new evidence suggests that the lack of stable relationship between hydroelectricity consumption and economic growth documented in previous studies for some of these countries could be due to the failure to properly account for the nonlinearity property in the data. 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
