In a Bayesian assessment, beliefs are computed from the strategy profile applying Bayes rule at positive probability information sets. A consistent assessment is the limit point of a sequence of completely mixed Bayesian assessments. We characterize the set of extensive forms for which the sets of Bayesian and consistent assessments coincide. As an illustration of the results, we characterize consistency in some multi-period games with simultaneous actions. 相似文献

Contributing to the debate on the macroeconomic effects of fiscal stimuli, we show that the impact of government expenditure shocks depends crucially on key country characteristics, such as the level of development, exchange rate regime, openness to trade, and public indebtedness. Based on a novel quarterly dataset of government expenditure in 44 countries, we find that (i) the output effect of an increase in government consumption is larger in industrial than in developing countries; (ii) the fiscal multiplier is relatively large in economies operating under predetermined exchange rates but is zero in economies operating under flexible exchange rates; (iii) fiscal multipliers in open economies are smaller than in closed economies; (iv) fiscal multipliers in high-debt countries are negative. 相似文献

This study investigates the relationship between U.S. state housing prices and overall U.S. housing prices as well as the relationship among state housing prices using fractional integration and cointegration techniques. The results based on parametric and semiparametric estimators reveal that some states contain unit roots though we fail to find cointegrating relations between U.S. states housing prices and the overall U.S. housing prices as well as among state housing prices. The results raise doubts regarding the long-run convergence in U.S. state housing prices and the presence of the ripple effect. 相似文献

This paper proposes a shadow value-based methodology for the economic valuation of environmental goods. The proposed method derives from a “cost of production perspective”. This type of approach represents advantages with respect to usual methods linked with “demand perspective”, when the interests of future generations is under consideration. The computational procedure is simple and the required information easy to obtain. We explain how the methodology works with the help of a forestry example. 相似文献

The Luenberger productivity indicator is employed to estimate and decompose productivity change in a sample of cooperative banks operating in 10 EU member states. An average annualised productivity growth of 2.59% is reported between 1996 and 2003, though there is heterogeneity in growth rates across countries. Generally speaking, productivity growth is driven by technological change. However, cooperative banks in southern European banking markets benefit as much from efficiency growth or catching‐up with industry best practice. The results suggest that technology sharing arrangements and greater competition arising from deregulation are positive contributors towards productivity change. 相似文献

In the context of either Bayesian or classical sensitivity analyses of over‐parametrized models for incomplete categorical data, it is well known that prior‐dependence on posterior inferences of nonidentifiable parameters or that too parsimonious over‐parametrized models may lead to erroneous conclusions. Nevertheless, some authors either pay no attention to which parameters are nonidentifiable or do not appropriately account for possible prior‐dependence. We review the literature on this topic and consider simple examples to emphasize that in both inferential frameworks, the subjective components can influence results in nontrivial ways, irrespectively of the sample size. Specifically, we show that prior distributions commonly regarded as slightly informative or noninformative may actually be too informative for nonidentifiable parameters, and that the choice of over‐parametrized models may drastically impact the results, suggesting that a careful examination of their effects should be considered before drawing conclusions. 相似文献

We characterize the class of finite extensive forms for which the sets of Subgame Perfect and Sequential equilibrium strategy
profiles coincide for any possible payoff function. In addition, we identify the class of finite extensive forms for which
the outcomes induced by these two solution concepts coincide.

In recessions, the number of defaulting firms rises. On top of this, the average amount recovered on the bonds of defaulting firms tends to decrease. This paper proposes an econometric model in which this joint time-variation in default rates and recovery rate distributions is driven by an unobserved Markov chain, which we interpret as the “credit cycle”. This model is shown to fit better than models in which this joint time-variation is driven by observed macroeconomic variables. We use the model to quantitatively assess the importance of allowing for systematic time-variation in recovery rates, which is often ignored in risk management and pricing models. 相似文献

Financial crises in emerging economies are accompanied by a large fall in total factor productivity. We explore the role of financial frictions in exacerbating the misallocation of resources and explaining this drop in TFP. We build a two-sector model of a small open economy with a working capital constraint on the purchase of intermediate goods. The model is calibrated to Mexico before the 1995 crisis and subjected to an unexpected shock to interest rates. The financial friction generates an endogenous fall in TFP and output and can explain more than half of the fall in TFP and 74 percent of the fall in GDP per worker. 相似文献
