The purpose of this paper is to integrate two commonly known input-output models of Leontief and Stone for employment analysis. Although assumptions of Leontief model are somewhat different from Stone's model, the empirical analysis can be conducted ignoring the difference between competitive and noncompetitive imports in the initial stage. The Leontief model is used to make predictions of gross domestic output on the basis of predicted imports and final demand by sectors. The predicted output is used to derive employment by sectors for a target year and this in turn is used in Stone's input-output framework for the analysis of total labour intensity by sectors. The approach on the estimates of labour intensity by sectors is illustrated using Japan's input-output data.  相似文献

Decision styles, defined by the primary and secondary considerations in choice making and the implementation tactics preferred by managers, are used to explain the ways in which managers with a given style take action. Examples are used to illustrate the unique approaches taken by managers with each style in their decisions concerning leadership, team building, strategic management, control, and related issues that managers grapple with to fashion a desired future. The basis for shifts in style and the potential for conflict or collaboration between individuals with particular styles is discussed.  相似文献

This paper examines the use of fines and imprisonment to deter individuals from engaging in harmful activities. These sanctions are analyzed separately as well as together, first for identical risk-neutral individuals and then for two groups of risk-neutral individuals who differ by wealth. When fines are used alone and individuals are identical, the optimal fine and probability of apprehension are such that there is some ‘underdeterrence’. If individuals differ by wealth, then the optimal fine for the high wealth group exceeds the fine for the low wealth group. When imprisonment is used alone and individuals are identical, the optimal imprisonment term and probability may be such that there is either underdeterrence or overdeterrence. If individuals differ by wealth, the optimal imprisonment term for the high wealth group may be longer or shorter than the term for the low wealth group. When fines and imprisonment are used together, it is desirable to use the fine to its maximum feasible extent before possibly supplementing it with an imprisonment term. The effects of risk aversion of these results are also discussed.  相似文献

经过简化的基于总收益形式的指数模型被经常用来估计证券贝塔,但这个模型没有理论依据。由于我国无风险利率的方差与市场收益的方差变动比较起来非常小,短期无风险利率的实际变动对贝塔估计值影响很小,因此,从“预测”的角度看,用总收益形式的单指数模型估计贝塔值可以完全替代具有理论基础的超额收益形式的单指数模型估计的贝塔。  相似文献

Hong Kong and Singapore are two of the most important and fastest growing markets for tourists to Australia. The purpose of this paper is to investigate movements in the long-run demand for tourist travel by these two origin countries for Australia. Some of the leading macroeconomic variables examined to explain tourism demand are incomes in Hong Kong and Singapore, tourism prices in Australia, and transportation costs and exchange rates between the two countries and Australia. Seasonally unadjusted quarterly data are used for Hong Kong for the period 1975(1)–1996(4), and for 1980(4)–1996(4) for Singapore. Several proxy variables are used for the incomes of tourists from Hong Kong and Singapore to explain quarterly tourist arrivals to Australia. The augmented Dickey-Fuller test for unit roots is examined in the univariate framework, and Johansen's maximum likelihood procedure is used to test for cointegration and to estimate the number of cointegrating vectors. Error correction models are estimated to explain quarterly tourism demand by Hong Kong and Singapore for Australia.  相似文献

The purpose of this paper is to propose alternative specifications which can be used for predicting imports by commodities for a large number of countries. Both “variety” and “scale” hypothesis have been made use of in suggesting simple cross-section relationships which can be easily used for predicting imports by commodities for any country of the world. Indeed, since detailed country characteristics are not taken into consideration in per capita income and population, it is likely that consistent under or overpredictions may result for a country when the estimated relationship is used. The extent of under or overprediction is reduced by using the variable elasticity formulation of the import demand function. Our estimates of cross-section relationships show remarkable stability in structural coefficients for the period 1967–1973 on the two-digit S.I.T.C. data. A set of eight different relationships is estimated and using 1970 cross-section relationships forecasts for 1973 and 1980 are given. Forecasts of imports of 45 commodities for 37 countries were derived and compared with the corresponding actual 1973 figures. The root mean square error predictive criterion suggests that per capita income and population in a constant elasticity form performs reasonably well.  相似文献

Does the P* Model Provide Any Rationale for Monetary Targeting?   总被引:1,自引:0,他引:1  
The so-called P * model is frequently used or referred to in discussions of monetary targeting. This gives the impression that the P * model might provide some rationale for monetary targeting or for the monetary reference value used by the Eurosystem. The P * model implies that inflation is determined by the level of and changes in the `real money gap' (the deviation of current real balances from their long-run equilibrium level), and hence that the real money gap is an important indicator for future inflation. Nevertheless, the P * model does not seem to provide any rationale for either a Bundesbank-style money-growth target or a Eurosystem-style money-growth indicator.  相似文献

Environmental cost-benefit analysis (ECBA) is used for the social evaluation of investment projects and policies that involve significant environmental impacts. Economic valuation of environmental impacts forms one of the critical steps of ECBA. We develop a new method for this purpose, which does not require price estimation for environmental impacts using stated or revealed preference methods. Our approach is based on data envelopment analysis (DEA), which is modified to ECBA by using absolute shadow prices instead of relative prices. We also discuss how the method can be used for sensitive analysis in ECBA. We illustrate the method by means of a hypothetical numerical example.  相似文献

Routines and the environment: Bridging the gaps   总被引:1,自引:0,他引:1  
The paper examines the hypothesis that the mechanisms used by firms to improve their environmental performance are organisational routines. The concept of routines has been developed by evolutionary economists to investigate firms' innovative behaviour, but it has not been used to study how firms address environmental issues. Based on an applicable definition of routines, a methodology is designed to identify environmental routines in a case study of 13 oil refineries located in four different countries. Results confirm the hypothesis for firms operating under strict environmental regulations (France, UK). A comparative analysis of the degrees of routineness of the environmental mechanisms used by case study firms reveals and explains important gaps between European and North African refineries. Solutions to reduce them are proposed.  相似文献

This paper explores the strategic actions realised by firms in the pharmaceutical industry during 2001 and 2002. The purpose was to develop an empirically derived categorisation of strategic actions and grand strategies from the behaviour of firms that could be used as the basis of a methodological framework for developing understanding of strategic change. Qualitative analysis was used to identify and categorise strategic actions implemented by pharmaceutical firms. Twenty-three grand strategies were identified and are described. Implications for further research in strategy development are discussed.  相似文献

This study departs from the previous literature on purchasing power parity (PPP) by proposing a demand system based methodology for calculating the PPP that takes account of consumer preferences and allows for the substitution effect of price changes. The methodology is used to calculate the PPP between the Indian Rupee and the Vietnamese Dong. The study allows for regional variation in preferences and price changes both inside the country and between countries. It proposes and applies a methodology for constructing prices from unit values after adjusting them for quality and demographic effects. The adjusted unit values are used as prices in the demand estimations, and the demand parameter estimates are used to calculate both spatial prices within each country and the PPP between the two countries within a consistent framework. The study illustrates the usefulness of preference consistent methods to calculate the PPP by applying the PPPs to compare living standards between India and Vietnam. The significance of the results follows from the fact that the levels of living comparisons are quite sensitive to the PPP used in converting the Rupee expenditure into Vietnamese Dong. The present results on food PPPs question the relevance of the PPPs from the ICP project in cross‐country welfare comparisons especially in a period of high food inflation.  相似文献

The Gini concentration coefficient is considered to be the best synthetic inequality measure and is widely used in economic research. In this paper, we present its decomposition by factor components with an application to income distributions in Poland. Income inequality measures proposed by Gini, Zenga and Bonferroni are calculated for different socio-economic groups based on their exclusive or primary source of maintenance. For theoretical income distribution, the Dagum type-I model was used. The basis for the calculations was the individual data coming from the Household Budgets Survey conducted quarterly by the Polish Central Statistical Office. Using the decomposition of inequality by source, we were able to examine how changes in particular income components affected overall inequality.   相似文献

This paper computes new indexes of output for refrigerators, using hedonic methods to adjust for quality change. The hedonic technique is applied in a new way (it is used to make quality adjustments to prices before they are used in the index), and the results are compared with those from methods used in previous hedonic investigations. There are three major findings. (1) Overall (1960–1972), our hedonic deflated output series rise more rapidly than conventional measures, because the price indexes used for deflation rise more slowly. (2) The output measures fluctuate more than do output measures produced by conventional methods, because adding hedonic quality adjustments to WPI indexes moves them up in some years and down in others, and the resulting adjustments to the output series were positively correlated with changes in output. (3) Applying methods used in previous studies produces larger adjustments to the published indexes, suggesting that some of the differences noted in previous studies between hedonic indexes and official published indexes are related to computational methods, not to quality adjustment.  相似文献
