We show how to decentralize constrained efficient allocations that arise from enforcement constraints between sovereign nations. In a pure exchange economy these allocations can be decentralized with private agents acting competitively and taking as given government default decisions on foreign debt. In an economy with capital these allocations can be decentralized if the government can tax capital income as well as default on foreign debt. The tax on capital income is needed to make private agents internalize a subtle externality. The decisions of the government can arise as an equilibrium of a dynamic game between governments. 相似文献

Price-Wage Dynamics and Inflation in Socialist Economies: Empirical Models for Hungary and Poland 总被引:1,自引:0,他引:1
This article analyzes the determinants of open inflation intransitional socialist economies, with reference to recent experiencein Hungary and Poland. A simple inflation model is centeredon the transmission process and on the short-run dynamics ofinflation. Further incorporating a number of features specificto socialist economies and working with quarterly data, dynamicprice and wage equations are estimated. The estimated equationsallow satisfactory exploration of the role and weight of foreignprices and domestic factors in propagating inflation. Foreignprices matter, but developments on the cost side are criticalin relating exogenous, policy-driven adjustments to the pricelevel to increases in the rate of inflation. The absence ofconventional market-based, equilibrating mechanisms requiresthat nominal anchors, particularly wage restraints, featureprominently in any stabilization program adopted by reformingsocialist economies. 相似文献

ABAPO 2.1 (Assets/Business(es) Analyser and Portfolio Optimizer) is a DSS prototype for portfolio managers. It assists the decision maker in two important stages of his task. First, it provides an integrated synthesis of the returns scenario in order to support the decision maker in the selection of the assets to retain, in accordance with his strategy. Second, on the retained assets it computes and shows the E- efficient solutions. For each efficient portfolio ABAPO supplies immediately a lot of information that should help the decision maker to single out the portfolio which fits his goals best.ABAPO works on an integration of elements derived from the Portfolio Selection Theory, the Capital Asset Pricing Model, the Utility Theory. ABAPO uses the principal component, the univariate, the bivariate regression and the correlation analysis, a parametric quadratic programming model and an algorithm based on the critical line method.ABAPO is implemented in C language under AIX operating system and runs on a IBM RT PC 6150. It is a ductile, interactive procedure that involves graphics in order to increase the efficiency and the effectiveness of the what if simulations.This version 2.1 improves upon the previous one by the evaluation of the Security Market Line, some statistics on the returns of the efficient portfolios, the evaluation of the quadratic indifference curves associated to the efficient portfolios.Research supported by the Italian National Research Council (CNR), grant n. 88.03065.10. ABAPO DSS 2.1 prototype has been developed with the support of the CNR (grant n. 87.1210.10), of the Banca Popolare di Verona, of the Cassa di Risparmio di Verona Vicenza e Belluno, of the Società Cattolica di Assicurazione, at the Istituto di Matematica, Università di Verona. 相似文献

Demand for product characteristics is examined within the context of models that allow for both corner and interior solutions corresponding to zero and non-zero demand. Product attribute information is associated with marginal utility and curvature (satiation) parameters of various utility functions. Empirical applications demonstrate the need for incorporating characteristics in a fairly general way. We also compare our approach to an ideal point and pure Lancasterian versions of our nonlinear utility model. The data support our model over either the ideal point or Lancasterian variants. 相似文献

Inter-enterprise arrears in economies in transition 总被引:1,自引:0,他引:1
In the context of economies in transition, the paper argues that an excessive liquidity squeeze could throw the economy into a persistent state of low economic activity. In such bad equilibrium, enterprise transactions become largely demonetized, with a chain of arrears, a form of involuntary credit, spreading over the entire system. The empirical analysis of the Romanian experience seems to support the view advanced in the paper. 相似文献

This paper assesses the impact of regulatory and environmental factors and statistical noise on the efficiency of public transit
systems within a DEA-based framework. Using a panel of Italian companies, we implement a DEA-SFA mixed approach based on [H.O.
Fried et al. (2002) Journal of Productivity Analysis, 17(1–2), 157–174] to decompose DEA inefficiency measures into three components: exogenous effects, managerial inefficiency and
stochastic events. Besides providing evidence on the determinants of input-specific efficiency differentials across companies,
the results point out that managerial skills play a minor role, and emphasize the relevance of regulatory policies aimed at
replacing cost-plus subsidization with high-powered incentive contracts as well as improving environmental conditions of public
transit networks.

This article presents evidence on the positive effect of international trade on productivity growth using industrial level data preceding and following Brazil's trade liberalization in 1988–90. Our data reveal large and widespread productivity improvement across industries after barriers to trade were drastically reduced. Econometric results confirm the association between trade liberalization and productivity growth and show that the impact was indeed substantial: The observed tariff reduction in the period brought a 6% estimated increase in total factor productivity growth rate and a similar impact on labor productivity. 相似文献

This paper analyses the re-emergence of small-scale production which has characterised the more recent phase of industrial development in Western countries, providing updated evidence about the phenomenon and focussing in particular the attention on Italy, where it has been assuming peculiar relevance.Data show that in the course of the '80s the main industrial European countries – with the notable exception of Germany – have experienced a further reduction in the average size of manufacturing firms, which was declining since the mid-'70s. Yet, in all of the countries concerned the increase of the relative "weight" in the employment shares of small enterprises is associated to an overall decline of employment levels in absolute numbers (smaller firm do not succeed in making up for the whole amount of job losses in the industrial sector).These trends appear particularly strong in the Italian manufacturing sector. In particular, a transition matrix drawn from a data-base of over 200,000 firms and data relative to birth and exit rates show that the rising importance of small firms in terms of employment (in particular within the range between 10 and 50 employees) has been linked to higher rates of growth with respect both to large enterprises and very small ones, as well as to a relatively higher "inertia" of their entry rates with respect to the latter. More specifically, data highlight a peculiarly low frequency of growing firms in the range including very small units (less than 5 employees); at the same time, such firms' exit rates do not show any tendency to be especially affected by the slowing down of economic activity in the late '80s. 相似文献

Accounting historians link the origins of cost accounting to the rise of manufacturing firms and, in a more detailed way, to efficiency control, pricing and decision-making problems faced in those organizations. To date, the international debate has mainly focused on practices in the USA, Great Britain and France, with little evidence available of developments in other countries, such as Italy. In this paper, the authors analyse the development of cost accounting in an Italian firm, 'La Magona d'Italia'. This iron, steel and tinplate firm, situated in Piombino, is observed over the period 1865-1940, i.e. during the central phase of the industrial revolution in Italy. We find that several factors influenced the implementation of a cost accounting system at Magona, including efficiency control, strategic decision making, and stock valuation. We also find a strong British influence on Magona's strategy, organization and information system, particularly in respect of finance, managers, technology and accounting practices. There is little evidence that Italian accounting traditions and practice played much of a role. 相似文献
