The model presented here is an estimated medium-scale New Multi-Country Model (NMCM) which covers the five largest euro area countries and is used for forecasting and scenario analysis at the European Central Bank. The model has a tight theoretical structure which allows for non-unitary elasticity of substitution, non-constant augmenting technical progress and heterogeneous sectors with differentiated price and income elasticities of demand across sectors. Furthermore, it has the explicit inclusion of expectations on the basis of three optimising private sector decision making units: i.e. firms, trade unions and households, where output is in the short run demand-determined and monopolistically competing firms set prices and factor demands. Labour is indivisible and monopoly-unions set wages and households make consumption/saving decisions.We assume that agents optimise under limited information where each agent knows only the parameters related to his/her optimisation problem. Therefore we estimate with GMM, which implicitly assumes limited information boundedly rational expectations. In this paper we provide some simulation results under the assumption of model-consistent rational expectations, we show that there is some heterogeneity across countries and that the reactions of the economies to shocks depend strongly on whether the shocks are pre-announced, announced and credible or unannounced and uncredible.  相似文献

This paper provides a formal model of endogenous border formation and choice of defense spending in a world with international conflict. We examine both the case of democratic governments and of dictatorships. The model is consistent with three observations. First, breakup of countries should follow a reduction in the likelihood of international conflicts. Second, the number of regional conflicts between smaller countries may increase as a result of the breakup of larger countries. Third, the size of the peace dividend (the reduction in defense spending in a more peaceful world) is limited by the process of country breakup.  相似文献

The fitness of an economy and its prospects for continued prosperity will be measured and determined by its robustness and its ability to adapt to changing circumstances. Some countries in transition are adapting much more easily than others to rapid changes in the orientation of their economy, the common objective of which is to achieve economic growth through the adoption of a range of characteristics generally associated with a market economy. Economic growth does not have to be very fast, but it must be efficient and sustainable. Policy adjustments must address political economy concerns, while seeking to achieve macroeconomic equilibrium and price stabilization, competitiveness, efficiency and flexibility, and the protection of the living standards of the most vulnerable population The process of agricultural sector reform will be determined both by economy-wide policies and sector-specific policies. This paper first outlines a taxonomy of the objectives of agricultural sector reform, and then discusses the way in which indirect price interventions (specifically exchange rate and interest rate policies, expansive fiscal policies and industrial protection policies), influence agricultural growth. Lessons of experience drawn from the UNDP/World Bank Trade Expansion Program structural and sectoral adjustment operations in Poland, and the cases of New Zealand and Chile are employed to illustrate not only the constraints that countries face in this regard, but also in identifying targets for further action. The third section presents what is called the architecture of incentives for agriculture'. In defining a strategy of agricultural sector reform, experience has shown that a structure of incentives can be developed that creates an environment ripe for agricultural growth-incentives relating, for example, to taxation, prices, foreign investment, privatization and demonopolization, decentralization and institutional reform. Special considerations that will require additional attention by policy-makers outside of this structure include the maintenance of GATT-legal principles in trade policies, issues relating to tariffication (including concerns about price risk management, food supply, and the role of food aid), input and credit subsidies as a means to correct for market failures, and the role of regional trading blocks in world trade.  相似文献

Analyzing synthetic cohorts in the 1980 and 1990 Public Use Microdata Samples, we find that Mexican‐Americans and other Hispanics acquired English fluency at a faster pace than Puerto Ricans and Cuban‐Americans during the 1980s. Additional results indicate that English‐skill investments differently influenced the earnings distributions of these ethnic groups.  相似文献

This article analyses the consequences of the money supply growth rate on capital intensity and economic growth in an overlapping-generations model with real balances entering the production function. Within this theoretical framework, anticipated inflation generates an ambiguous effect on capital–labour ratio, because two forces work simultaneously in opposite directions: one driving towards a pure Tobin effect (due to the OLG demographic structure of the economy) and the other pushing down the capital stock (due to the productive role of real balances). Despite the unclear effects exerted on capital intensity, higher monetary growth rates unambiguously reduce real money demand, consumption, total wealth and welfare.  相似文献

In this paper, we test whether European consumers are addictive smokers and, if this is the case, then whether such addictions can be explained by the rational addiction theory. To this end, we start from a non‐separable intertemporal utility function, which allows us to derive a demand function that is estimated using tobacco time‐series. The results are in accordance with the model of rational addiction for all European smokers. Thus, we observe the addictive character of tobacco consumption and, secondly, we note that the addiction is not the result of myopic consumer behaviour, but rather of the maximization of total utility, implying that consumers consider the future effects of their current decisions.  相似文献

The intensive use of pesticides in countries like Brazil has ignored structural and institutional shortfalls, such as the lack of workforce training for the new, difficult to implement technologies, and the institutional vulnerability of the environmental protection, health, and safety sectors. As a result we have “invisible” or social, environmental and health costs which end up being socialised with the farmer, in general, having no incentives to recognise and internalise them. This study is intended to review and develop this problem in the light of the Brazilian reality. To this end, we make use of an empirical exercise to illustrate estimation of the social cost associated with acute poisoning by pesticide using the PREVS/IBGE data (Harvest Forecast Research) in the state of Paraná, Brazil. The results suggest that, for maize, the costs of acute poisoning could represent 64% of the benefits of using herbicides and insecticides, and, in the best of hypotheses, when some risk factors are eliminated, they may reach 8% of the benefits of the use of these products. Similarly, when we examine future scenarios for five and ten years, we find less encouraging results, as in ten years the costs of acute poisoning could reach around 85% of the benefit of using insecticides and herbicides for maize. However, there is the encouraging news that, if preventive measures were taken during this time, the gains would be considerable, about 6.5 times greater. We conclude that an assessment of the real benefits involved with pesticides in Brazil is required, principally in regard to the smallholder, where farmers need more training in the use — or even the elimination — of these hazardous substances. There are sustainable technological options available which are economically efficient, especially if we consider the social, environmental and health costs. In this context it is worth highlighting the role of regulatory measures as a mechanism which can reorient generation of negative external costs through the reduction of current incentives in the socialisation of private costs.  相似文献

In spite of the increase in domestic law enforcement policies in the U.S. drug related crime has followed a non-monotonic trend and cocaine and heroin prices, instead of increasing, have been dropping or remained stable over time. All this in a context of an increase in these drugs’ consumption during the 1980s and a small decrease during the 1990s. This paper provides an explanation to these counter-intuitive effects of domestic law enforcement policies. We model how drug lords respond to this type of policy within a conflict framework over the control of distribution activities for illegal drugs, which is novel. The model predicts drug distribution activities, drug prices and drug consumption. These predictions appear to be consistent with the empirical evidence in the United States.  相似文献

A home firm signals her private cost information by expanding in a foreign firm’s country. Credible signaling to deter counter‐entry may occur through a direct investment (but not through exports), and may even entail entering an unprofitable market. While this produces social benefits, uninformative signaling may be welfare‐reducing. Hence, we argue that moderate to high location costs may be socially desirable. We also show that there are not simple monotonic relationships between technology/demand conditions and firms’ entry modes. Thus, the signaling interpretation of international expansion makes it possible to explain some controversial empirical findings on a theoretical ground.  相似文献
