Summary This paper formulates an optimizing model of a small open economy with a representative (immortal) household, a firm and a government. The asset menu consists of domestic currency, non-traded bonds and traded bonds. There is a risk premium on traded bonds, which leads to deviations from perfect capital mobility and uncovered interest parity. Taxes are lump-sum, so that finance by bonds and by taxation are equivalent. The model allows for current-account and wealth dynamics. The model assumes either purchasing power parity or imperfect substitution between home and foreign goods and either labour market equilibrium, nominal wage rigidity or real wage rigidity. The steady-state effects of a fiscal contraction, a monetary disinflation and an increase in the world interest rate are discussed. The transient effects of these policies are analysed with the aid of a multiple shooting algorithm.We thank Gerard Staarink for implementing the multiple shooting algorithm used in section 4 and we thank Professors M. Fase and J. Pen for their constructive comments on a previous version of this paper. The paper is a shortened version of discussion paper No. 168 of the Centre for Economic Policy Research, London.  相似文献

Rationing in open economy and dynamic macroeconomics: A survey   总被引:1,自引:1,他引:0  
Summary A survey of rationing in micro theories of macroeconomics is presented. The survey starts with a closed economy with money and inventories, which consists of a representative household, a firm and government. After a discussion of the notional demands and supplies and the properties of the Walrasian equilibrium, a discussion of the effective demands and supplies leads to an analysis of the four regimes (Keynesian unemployment, classical unemployment, repressed inflation and underconsumption). A fiscal and monetary contraction decreases sales and employment when there is Keynesian unemployment, but is expansionary (neutral) when there is repressed inflation (classical unemployment). The survey continues with an analysis of the effects of rationing in a small open economy. It considers the one-sector model and a model with a traded and a nontraded sector. The latter model is used to discuss the effects of an oil discovery on the Gulf countries and on Latin American countries. The survey ends with a discussion of rationing in dynamic economies, which leads to an analysis of the effects of expectations about future constraints on current regimes and to a discussion of boot-strap equilibria.The author is Director of the Network for Quantitative Economics. This paper is a brief and eclectic survey of rationing models of closed one-period and two-period economies and of small open economies. It contains no significant new material. The author is grateful to Professor Theo van de Klundert for his constructive comments on an earlier version of this survey.  相似文献

A windfall in a developing economy with capital scarcity and investment adjustment costs facing a temporary windfall should be used to give more consumption to poorer present generations and to speed up development by ramping up public investment and paying off debt taking due account of the increasing inefficiency as investment gets ramped up. The optimal strategy requires negative genuine saving; the permanent income requires zero genuine saving. The optimal real consumption increments are smaller once one allows for absorption constraints resulting from Dutch disease and sluggish adjustment of ‘home-grown’ public capital.  相似文献

In this paper we revisit the Dutch disease paying particular attention to the role of specific factors of production and capital stock dynamics. The main insight is that if the natural resource rich windfall is substantial but not large enough for the country to become a rentier, capital goods must be produced at home and adjustment to natural resource windfall takes time. It takes time to build this home-grown capital. Specific factors are crucial to explain the dynamic responses of the real exchange rate, capital intensities and wages in response to a natural resource windfall. If a country is small and the windfall is large, it may be able to import capital and migrant labour in which case the Dutch disease can be avoided.  相似文献

Economic data are typically inconsistent with national accounting identities, contain measurement errors and are sometimes unavailable. A generalized conditioned least square procedure for the adjustment of data is proposed to deal with these problems. It is shown how the resulting data may be used for FIML estimation of the parameters of dynamic models (and the data themselves) with the aid of the Kalman-Bucy filter. An illustrative application of the proposed techniques to UK data is reported.  相似文献

In Art we trust   总被引:1,自引:0,他引:1  
Culture is an experience good and has strong externalities. Culture has social value, option value, existence value, innovation value, and intergenerational value. None of these are internalised by the market. One should avoid that culture appeals to a small elite. It is thus crucial to invest in cultural education, to bring culture to places where the people are, and to put a greater emphasis on demand-side rather than supply-side cultural subsidies. One should try to avoid that high culture becomes marginalised in a multicultural society with many demands on leisure time. The government should avoid deadweight losses, but should also minimise the potential for rent seeking and lobbying. It is crucial that the government stays at arm's length and leaves artistic judgements to independent experts and interested laymen.  相似文献

The paper considers the estimation of the coefficients of a single equation in the presence of dummy intruments. We derive pseudo ML and GMM estimators based on moment restrictions induced either by the structural form or by the reduced form of the model. The performance of the estimators is evaluated for the non-Gaussian case. We allow for heteroscedasticity. The asymptotic distributions are based on parameter sequences where the number of instruments increases at the same rate as the sample size. Relaxing the usual Gaussian assumption is shown to affect the normal asymptotic distributions. As a result also recently suggested new specification tests for the validity of instruments depend on Gaussianity. Monte Carlo simulations confirm the accuracy of the asymptotic approach.  相似文献
