This article deals with some aspects of the compilation of input-output tables (I.O. tables). A global view is given of the way in which I.O. tables are compiled in The Netherlands. It is indicated that in The Netherlands a number of developments are in progress that have led to an extension of the uses that are made of I.O. tables. The changing demands on I.O. tables that result from these developments can be met in future to an important degree. This has been made possible by extending and improving basic statistics and by increasing the uses made of automation facilities. Some problems remain, however, and one of these problems takes a central place in this article. This is the problem of accuracy and continuity: how can yearly I.O. tables be compiled that combine accuracy with consistency over time. Accuracy means here that the tables should be as complete as possible and in optimal accordance with all available information. Consistency over time means that estimates of details of I.O. tables compared with the same estimates for previous years reflect real economic developments. It is obvious that those two demands may conflict, particularly for years in which new information becomes available. It then must be decided whether accuracy or consistency in time deserves priority. What problems result from this decision and what are the consequences for the yearly I.O. tables? The problems arising from the conflicting demands of accuracy and continuity apply to the Netherlands in the last few years. This led to a revision of I.O. tables and national accounts for 1977. This revision resulted in an increase of estimated national income of more than 6 percent. For some components the adjustments have been much larger; this is particularly true for the services sector. More information on the 1977 revision is given in an annex.  相似文献

"This paper looks at the changes in headship rates in Great Britain over the period 1960-1979, and attempts to explain them in terms of economic variables, such as real income and the real cost of housing. Such variables are found to be significant for some household types, but not for others. Notably, young single person household formation appears to be more supply constrained and to respond to appropriate supply variables." Furthermore, "some comparisons are made with similar studies done on similar data from the USA and France. These studies reveal a number of features in common, but also some differences, and these are commented upon."  相似文献

The authors examine sex differentials in sustenance and survival in developing countries using the example of India. Lower female life expectancy at birth and the declining ratio of females to males are discussed as evidence of female deprivation. Consideration is given to the feeding, survival, and neglect of female children, to differences in use of medical facilities by sex, and to regional differences by state. This pattern of discrimination is found to persist even in urban areas.  相似文献

Recent literature has made significant progress in characterizing those social choice functions that can arise, or be “implemented,” as the equilibria of an underlying noncooperative game. This paper studies the implementability of social choice functions via cooperative games. Specifically, we show that if a social choice function arises, in each environment, as a Von Neumann-Morgenstern solution of an underlying cooperative game, whose dominance structure is monotonic and neutral, then the social choice function is essentially oligarchic, in exactly the same sense that “core” selecting choice functions are oligarchic.  相似文献

Estimates of the Allen partial elasticities of substitution (AES) for a regulated cost function [Smith (1981)] are compared with those obtained from an unregulated cost function. The AES for capital and variable inputs are reasonably similar, but those between variable inputs differ significantly.  相似文献

In this paper we offer a definition of a country "debt crisis" based upon the amount of new borrowing relative to the cost of servicing past debt. Policy implications for both debtor countries and their creditors are examined. An empirical application is made to Latin American countries, 1978–82. The causes of the debt problems created during this period are investigated with respect to the extent they were the result of rising interest rates vis à vis increased borrowing.  相似文献

Intrapreneurial activity is positively associated with the organizational growth, and the factors that stimulate such behaviors need to be identified. The general goal of this work is to explore the relationship of authentic leadership with employees’ intrapreneurial behavior and the intervening processes. A correlational study was carried out with 212 employees of Spanish companies, in which two cross-level mediation hypotheses were tested. The results obtained indicate that employees’ organizational identification and organizational empowerment both mediate the relationship between authentic leadership and employees’ intrapreneurial behaviors. In this work, we note the importance of including authentic leadership as an antecedent of intrapreneurship.  相似文献

In much of the literature, the debate over technical trading strategies has centered around the question of whether an actively managed portfolio, controlled by a technical indicator, can outperform a passively managed portfolio. Typically, the time horizon is considered to be years. Additionally, the trader is assumed to use a technical trading strategy that is independent of asset conditions. These assumptions may not correspond well with reality. Traders often have much shorter time horizons and may switch between rebalancing or trading strategies on the basis of perceived shifts in market condition. This paper presents a study of the profitability of technical trading rules as a function of asset state or condition. Several common technical trading strategies were run on 296 stocks over a 15 year period. Strategies were run with 1 month rolling time horizons, significantly shorter than those used in similar studies in the literature. Stocks were segmented based on volatility and volume, which allowed for the examination of a strategy’s performance in different asset conditions. Several strategies were demonstrated to have consistently better risk-to-reward ratios under specific asset conditions and short time horizons. This finding helps to explain why some practitioners implement technical trading strategies.  相似文献
