We study the reform of the Spanish public pension system in a multiperiod, general equilibrium, overlapping generations model economy populated by heterogeneous households. Our households differ in their place of birth, in their age, in their education and, endogenously, in their employment status, in their wealth, and in their pension entitlements. They receive a stochastic endowment of efficiency labor units each period. And they face a disability risk and a survival risk. They understand the link between the payroll taxes that they pay and the public pensions that they receive. And they decide how much to consume and to work, and when to retire from the labor force. We calibrate this economy to Spanish data, and we use it to study the consequences of delaying three years the statutory retirement ages in 2010. We find this reform is sufficient to solve the sustainability problems that plague the current Spanish public pension system. Our model economy predicts that under the current rules, the pension system fund will run out in 2028 and in the reformed economy it will last until 2050. We also find that it is moderately expansionary, and that it improves social welfare from the year 2015 onwards. We conclude that policymakers should seriously consider delaying the statutory retirement ages in Spain sometime in the near future.  相似文献

Because of the socioeconomic importance of the housing subsector in the local, regional, and national economy and its implications for housing policy, this paper attempts to analyze the spatial behavior of the free housing price in the city of Albacete. To achieve this aim, the authors have used the models and estimators imported from geology called kriging. To do this, it is necessary to know the spatial dependence structure of the process, which is shown in the variogram.  相似文献

The research reported in this article examines the influence of the organizational context of firm on their entrepreneurship. Specifically, this study examines how the organizational context variables of age, size, resources and competitive strategy affect entrepreneurship and in particular, innovation, proactiveness and risk-taking. Results from a sample of 233 firms showed, as hypothesized, the significant influence of resources and competitive strategy on entrepreneurship. However, size and age were not significant.  相似文献

With the introduction in 1968 of the New Economic Mechanism, the reformers of the Hungarian economy hoped to solve the eficiency problem of the socialist economy. It is shown that the survival of the previous structure of prices and accumulation and their interrelationships hindered the necessary transformation of the economic structure. Quantitative aspects of this process are analysed using a closed input–output model. The computed price and production structures are in correlation, which is the consequence of such a development policy where industry's share in investments is high when the investment growth rate is high and vice versa. The ratio of the computed disaggregated and aggregated growth rate is defined as a certain efficiency measure, and this coefficient shows that the Hungarian economy could only absorb the import surplus at a decreasing rate of efficiency. Despite the improvement in the early 1980s the question remains whether the Hungarian economy is able to growth both faster and efficiently at the same time.  相似文献

In the field of territorial economic growth, it is possible to identify important characteristics in the entrepreneurial structure, such as the structure of the size of firms, main activity sectors, or the degree of innovation. However, other lesser known characteristics are important also, such as functional dependency, which considers the relationship between small and medium enterprises (SMEs), and suppliers and clients belonging to any territorial field or productive dependency, which considers the level of concentration in terms of buying and selling in connection with the main suppliers and clients, respectively. In order to empirically contrast the importance of these entrepreneurial characteristics and try to relate them with territorial economic growth, a sample of 400 enterprises in the province of Seville (Spain) is used.   相似文献

This paper presents the results of empirical research on the use of time‐based postponement in a supply chain context using data collected from two manufacturers, a distributor, and a retailer. The analysis shows that implementing postponement at the firm level can result in the supply chain carrying more inventory. In order to achieve its full potential, postponement needs to be implemented across organizations in the supply chain.  相似文献

Mining cycles have had an enormous impact in the evolution of the localisation of economic activity, in particular of industry, in Chile. The nitrate cycle was characterised by a labour‐intensive extraction process and activity which was geographically very concentrated. The copper cycle was geographically more dispersed and its activity more capital‐intensive. We stress the role played by the State in the latter de‐concentration due to the impact of regional development policies and assess the importance of factor endowments and agglomeration economies, in the localisation of the manufacture.  相似文献
