Several new parameters characterizing the shape of statistical distributions are discussed. These parameters have earlier been considered for characterization of the shape of territories. By means of these parameters we describe general spread and spread along the axes, as well as asymmetry, of univariate theoretical and empirical distributions. General formulas for the parameters are given, and the particular formulas for the most of the common theoretical distributions are also listed. Some numerical values are tabulated, to illustrate their usefulness. Affine transformations are considered, and many applications and extensions are hinted upon. 相似文献

“Set a Sufficiently Ambitious Budget Target and Let the Automatic Stabilizers Work”. Will it Really Work in the European Monetary Union? 总被引:1,自引:1,他引:0
We examine the popular recipe in the title by means of an AD-LM-AS two-country model of the EMU, controlling for asymmetry in demand and supply shocks and in the monetary-policy transmission mechanism. Unless structural symmetry holds and symmetric shock occurs, national automatic stabilizers, even though supplemented with the common monetary policy, cannot deliver optimal stabilization in each economy. Inflation and output gaps are not closed and may be divergent in sign. Considering that a federal system of inter-regional insurance is lacking, the recipe under examination is too optimistic, while serious threat to EMU cohesion may arise. The econometric estimates we present show that existing national fiscal systems work very poorly as for the minimization, after shocks, of the dispersion of national incomes around the EMU average. 相似文献

Most of the countries of the OECD offer quarterly estimates of their national growth or of their Gross National Product. Official Statistical Agencies in western countries have to deal with the problem of estimating Quarterly National Accounts series congruently with Annual National Accounts. In Spain, the Instituto Nacional de Estadística uses the Chow-Lin disaggregation method, which is based on information provided by a group of high-frequency related variables, to estimate the quarterly components of National Accounts from annual components. In this paper, we analyse the relative quality of the estimates obtained through the Chow-Lin procedure, under different sets of hypotheses.JEL Classification:

Ignoring the existence of the zero lower bound on nominal interest rates one considerably understates the value of monetary commitment in New Keynesian models. A stochastic forward-looking model with an occasionally binding lower bound, calibrated to the U.S. economy, suggests that low values for the natural rate of interest lead to sizeable output losses and deflation under discretionary monetary policy. The fall in output and deflation are much larger than in the case with policy commitment and do not show up at all if the model abstracts from the existence of the lower bound. The welfare losses of discretionary policy increase even further when inflation is partly determined by lagged inflation in the Phillips curve. These results emerge because private sector expectations and the discretionary policy response to these expectations reinforce each other and cause the lower bound to be reached much earlier than under commitment. 相似文献

Income distribution affects market demand and its elasticity, and, as a consequence, the optimal behaviour of firms and market equilibrium. This paper focuses on the effects of income polarization, and presents a model where – for any unimodal density function describing income distribution of the consumers – income polarization leads to market concentration, i.e., to a smaller number of firms able to survive in the long run, provided that the firms' fixed costs are sufficiently low. 相似文献

This paper analyses exploitation and class formation in a dynamic context. An intertemporal model of a subsistence economy is set up and, among other results, it is proved that, in an interior equilibrium, Differential Ownership of (Scarce) Productive Assets is an inherent feature of a capitalist economy, while exploitation tends to disappear in the long run. Asset inequality is therefore proved to be a normatively secondary (though causally primary) wrong. It is also argued that these results raise several doubts about the possibility of providing robust micro-foundations to Marxian concepts by means of Walrasian general equilibrium models. 相似文献

In this paper we study a particular case of “multiple” externalities associated to the production of a good/activity, whose
external effects can change from positive to negative depending on the level of output (intersecting externalities). To analyze their impact on the public policy we propose a very simple two-agent partial equilibrium model in the technological
context of externalities. In a static framework, the centralized solution always implies an optimal policy, which may consist
of taxation or subsidization depending on the individual optimum and on the technology parameters. In a dynamic model with
local knowledge of the efficiency function and instantaneous output adjustments, such an optimal policy can be structurally
stable or unstable. In the latter case, under small changes of the parameters the policy may switch from low taxation/subsidization
to high taxation/subsidization or vice versa, or even jump discontinuously from taxation to subsidization or vice versa. Furthermore, the decentralized solution based upon “tradable rights” can be economically equivalent to the centralized solution
in the form of taxation policy but the two solutions may be not politically equivalent.

Multiple time series data may exhibit clustering over time and the clustering effect may change across different series. This paper is motivated by the Bayesian non-parametric modelling of the dependence between clustering effects in multiple time series analysis. We follow a Dirichlet process mixture approach and define a new class of multivariate dependent Pitman–Yor processes (DPY). The proposed DPY are represented in terms of vectors of stick-breaking processes which determine dependent clustering structures in the time series. We follow a hierarchical specification of the DPY base measure to account for various degrees of information pooling across the series. We discuss some theoretical properties of the DPY and use them to define Bayesian non-parametric repeated measurement and vector autoregressive models. We provide efficient Monte Carlo Markov Chain algorithms for posterior computation of the proposed models and illustrate the effectiveness of the method with a simulation study and an application to the United States and the European Union business cycle. 相似文献

By employing a Granger causality methodology in a panel data framework, this article explores the relationship among efficiency, capitalization and credit risk within the local Italian banking system. Focusing the attention on cooperative banks, we specifically test whether managers take more risks in highly concentrated markets (i.e. monopoly) than in partially competitive markets (i.e. duopoly). The evidence shows that in more concentrated markets, management efficiency generates a decrease in risk-taking (rejecting the bad management hypothesis) with respect to the partially competitive markets. Results are consistent with the idea that banks with less local competition are able to increase their profits by indulging more freely in rent-seeking behaviour, minimizing their risk-taking and, consequently, improving the quality of their assets through additional screening processes. The financial crisis does not seem to affect the conduct of management in terms of bank investment decisions and risk-taking. A series of robustness tests generally confirms our findings. 相似文献

We argue that to support agriculture–environmental policy decision making, stakeholders need ‘quantitative back‐of‐the‐envelope’ analysis that is timely and sufficiently accurate to make informed decisions. We apply this concept to the analysis of the supply of ecosystem services from agriculture. We present a spatially explicit production model and show how it can be used to derive the supply of ecosystem services in a region. This model shows that the supply of ecosystem services can be derived from the spatial distribution of opportunity cost of providing those services. We then show how this conceptual model can be used to develop a minimum‐data (MD) approach to the analysis of the supply of ecosystem services from agriculture that can be implemented with the kinds of secondary data that are available in most parts of the world. We apply the MD approach to simulate the supply of carbon that could be sequestered in agricultural soils in the dryland grain‐producing region of Montana. We find that the supply curve derived from the MD approach can approximate the supply curve obtained from a more elaborate model based on site‐specific data, and can do so with sufficient accuracy for policy analysis. 相似文献
