If Tunisia is hailed as a success story with its high rankings on economic, educational, and other indicators relative to other Arab countries, the popular 2011 uprisings underscored the fragility of its main economic pillars, including those of tourism and foreign direct investment. This paper examines the economic impact of migrants’ remittances, which are expected to exhibit relatively countercyclical behaviour during periods of intense upheaval. This study is novel in its methodological approach, which is used to pinpoint the dynamic effects of remittances on key macroeconomic variables within an unstable framework. The analysis reveals that the effect of remittances on Tunisia's economy has varied over time. Prior to the Arab Spring, remittances had a short‐term negative influence on economic growth, varying effects on domestic investment and positive impacts on consumption. In considering the post‐Arab uprisings, positive and strong impacts of remittances on growth and consumption are found in the long run while negative and moderate investment effects of remittances are shown over the short and medium term.  相似文献

Information and communication technology (ICT) products have undergone rapid technical change. Where quality improvements occur, they should be reflected in official price and quantity indices, otherwise there is a tendency to over-estimate price movements and under-estimate volume changes of ICT products. Statistical offices deal with this issue but the degree and nature of quality-adjustment of price indices of ICT products varies considerably between OECD countries. The present study simulates measurement effects on key economic variables (real output, private final consumption, government expenditure, investment, exports and imports) and productivity, under the assumption that the price indices of ICT products are fully quality-adjusted. The paper draws on a large selection of empirical studies to identify differences between quality-adjusted and unadjusted price changes and uses detailed information from input-output tables to assess their weights in final demand. Effects on GDP and its components are quantified for five selected OECD countries.  相似文献

This paper analyzes the economic impacts on different regions of the world of a global agreement to limit carbon emissions. A multi-sector, multi-region trade model (MS-MRT) is developed that focuses on the international trade aspects of climate change policy. These include the distribution of impacts on economic welfare, international trade and investment across regions, the spillover effects of carbon emission limits in Annex 1 countries on non-Annex 1 countries, carbon leakage, changes in terms of trade and industry output, and the effects of international emissions trading. Our central estimates are presented with a set of sensitivity tests to assess the extent to which our conclusions depend on elasticity and baseline assumptions. A technical appendix presents algebraic details of the model structure and calibration.  相似文献

The paper presents a small macro model for Pakistan economy focusing the impact of investment in human capital on the key macroeconomic variables. The demand side is modeled along the Keynesian lines while the supply side is modeled as per neoclassical theory of production. This framework allows analyzing the effects of investment in human capital on supply side variables (like labor, physical and human capital) and demand side variables (like consumption and investment) at the same time.The model has small forecasting horizon in which three alternative scenarios regarding government spending on education are evaluated from 2012 to 2016. The model shows that the link between human capital and labor market is weak however a change in education spending affects output through enhancing productivity and through multiplier-accelerator principle. Though the model is small in size and forecasting horizon, it can help in evaluating the future paths of key macroeconomic variables associated with education spending.  相似文献

Between 1940 and 2000 there was a substantial increase in educational attainment in the United States. What caused this trend? We develop a model of human capital accumulation that features a nondegenerate distribution of educational attainment in the population. We use this framework to assess the quantitative contribution of technological progress and changes in life expectancy in explaining the evolution of educational attainment. The model implies an increase in average years of schooling of 24%, which is the increase observed in the data. We find that technological variables and in particular skill‐biased technical change represent the most important factors in accounting for the increase in educational attainment. The strong response of schooling to changes in income is informative about the potential role of educational policy and the impact of other trends affecting lifetime income.  相似文献

Directed Technical Change   总被引:36,自引:0,他引:36  
For many problems in macroeconomics, development economics, labour economics, and international trade, whether technical change is biased towards particular factors is of central importance. This paper develops a simple framework to analyse the forces that shape these biases. There are two major forces affecting equilibrium bias: the price effect and the market size effect. While the former encourages innovations directed at scarce factors, the latter leads to technical change favouring abundant factors. The elasticity of substitution between different factors regulates how powerful these effects are, determining how technical change and factor prices respond to changes in relative supplies. If the elasticity of substitution is sufficiently large, the long run relative demand for a factor can slope up.
I apply this framework to develop possible explanations to the following questions: why technical change over the past 60 years was skill biased, and why the skill bias may have accelerated over the past 25 years? Why new technologies introduced during the late eighteenth and early nineteenth centuries were unskill biased? What is the effect of biased technical change on the income gap between rich and poor countries? Does international trade affect the skill bias of technical change? What are the implications of wage push for technical change? Why is technical change generally labour augmenting rather than capital augmenting?  相似文献

This paper analyzes patterns of foreign direct investment in India. We investigate how labor conflict, credit constraints, and indicators of a state's economic health influence location decisions of foreign firms. We account for the possible endogeneity of labor conflict variables in modeling the location decisions of foreign firms. This is accomplished by using a state‐specific fixed effects framework that captures the presence of unobservables, which may influence investment decisions and labor unrest simultaneously. Results indicate that labor unrest is endogenous across the states of India, and has a strong negative impact on foreign investment.  相似文献

Does population aging and the associated increase in the old‐age dependency ratio affect economic growth? The answer is given in a novel analytical framework that allows for population aging to affect endogenous capital‐ and labor‐saving technical change. In a steady state capital‐saving technical progress vanishes, and the economy's growth rate of per‐capita variables reflects only labor‐saving technical change. The mere possibility of capital‐saving technical change is shown to imply that the economy's steady‐state growth rate becomes independent of its age structure: Neither a higher life expectancy nor a decline in fertility affects economic growth in the long run.  相似文献

The purpose of this article is to measure the impact of military technology transfer on economic growth for 67 selected countries during the period 2000 to 2005 through the application of the Malmquist productivity index, which is broken down into efficiency change and technical change. Our main findings are as follows. First, technology diffusion is all-pervading in half of the sampled countries due to pure efficiency and scale efficiency changes. Second, a higher-income level and an excess of arms imports lead to innovative activities. Third, middle-income countries have higher efficiency and pure efficiency changes; these contribute to higher total productivity change. Finally, after separating the impact of capital investment from that of arms imports, the diffusion of military technology has a more positive and substantial impact on economic growth, thereby revealing the presence of externalities between countries.  相似文献

Almost all model simulations of CO2 reduction policies focus on the effects of changes in the relative price of energy compared to the other factors of production caused by various energy taxation schemes. Typical results of these simulations as reported e.g. from the GREEN model of OECD show depressing effects on real GDP and upward pressures on inflation.We propose the hypothesis that these results may be biased due to an inadequate treatment of technical progress and proceed as follows: Firstly, instead of treating technical progress as exogenous we explicitly model theprice induced change of the composition of capital stock of households and producers with its effects on energy efficiency and investment demand. Secondly, we investigate to what extent adouble dividend policy which boosts CO2 reduction technologies by special programs funded by the additional tax revenues differs from the mere price induced technological changes.We implement these propositions within the framework of a macroeconometric model for Austria which emphasizes substitution between energy and capital in providing energy services for households and producers. The following results are obtained: Firstly, we indicate how misleading the GDP effects may be if they result from lower energy intensities but still maintain the required energy services. Secondly, we investigate the effects of various energy taxation policies under different compensation schemes. Instead of merely relying on price-induced technological change we strongly advocate compensation programs which provide additional incentives for implementing high efficiency energy technologies such as cogeneration equipment or buildings with improved thermal standards.  相似文献

Technological change is modeled as endogenous in the sense that it is affected by economic, behavioral, and institutional variables. Technological change is especially affected by changes in relative input prices and their level, of which the price of labor is particularly important. Input prices are affected by institutional variables. Such prices also impact on the firm's efficiency, which in turn affects growth rates as well as the rate of technical change. As relative factor prices or their level increase, firms are induced to innovate or adopt extant technology to remain competitive or to maintain current profit rates. High wage firms can be expected to engage in such induced technological change, leading the growth process thereby yielding lower unit costs and increasing the level of material welfare. Relatively low wage economies can be locked into a state of economic inefficiency and laggard technological progress, especially in the long run.  相似文献

This paper estimates import demand and export supply functions for Korea based on the translog restricted profit (or GNP) function. It also estimates biases of technological change and applies decomposition analysis to examine the effects of technical change on input demand within the profit function framework. Our findings show that (a) factor inputs, as well as outputs, are, in general, moderately price-elastic and substitutable among each other. (b) the production of investment goods, as well as export goods, is capital-intensive while the production of consumption goods is labout-intensive, (c) technical change is labour-saving and is biased against imports, and (d) there has been a rapid decline of export supply price-elasticity which may be attributable to the rapid growth of export share of GDP (from 4% in 1964 to 38% in 1983). The larger the relative size of export sector and the faster the rate of its growth, the harder will it be to expand export production by drawing own resources from the domestic sector.  相似文献

Abstract ** :  In this paper, we examine the relationship between economic and environmental performance. More specifically, we analyse the impact of SO2 reduction in the eighties (1980–1992) on productivity growth, technical efficiency and technological progress for a set of 12 OECD countries. Our timeframe roughly corresponds to the adoption and implementation of the First Sulphur Protocol signed in 1985. First, we estimate an output based Malmquist productivity index using distance functions derived from successive DEA (Data Envelopment Analysis) frontiers. This index is decomposed in two components namely technical and efficiency change. Second, we regress the change in productivity and its two components on a set of explanatory variables including annual variations in SO2 emissions. The results indicate that reductions in SO2 do not seem to have had a significant impact on productivity growth. The decomposition into efficiency and technology changes suggests that two countervailing effects may explain this result. On one hand, SO2 cutbacks adversely affect efficiency but on the other hand, they stimulate technical change .  相似文献

Patterns of causation between income, export, import and investment growth for 39 developing countries are examined using model selection techniques which are based on ex ante predictive ability criteria to identify the best predictive model for each country. In particular, we look at the incidence of causation and reverse causation between various economic variables which are commonly believed to lead economic growth and find that there is less reverse causation from income to these variables than previously thought. We also construct an index of global business cycle conditions and find that models of countries with high trade exposure, growth rates and investment rates tend to gain in predictive ability from the addition of this variable.  相似文献

Spillover effects are treated as the influence of knowledge and innovation diffusion on an economic activity, but their analysis related to environmental practices within firms is still quite scarce. This study investigates the effect of environmental practices and related spillovers on productivity and efficiency in agri-food firms located in Southeast Spain. The low investment in research and development actions in comparison with the industrial sector, together with the relatively recent application of environmental requirements and the heterogeneity of environmental controls within firms have led to important changes in the organisation and management of their productive activity. These features are especially related to the implications that location and clustering factors have on environmental knowledge and innovation diffusion. Taking environmental management practices as knowledge of capital, we propose a specific analysis that evaluates the impacts of both environmental investment and spillover on the production function. The results indicate the relationship between productivity improvement and environmental practices, also showing the presence of positive spillovers. In a second-stage analysis, the incidence of environmental variables on the individual technical efficiency of firms is also determined. On the whole, the empirical analysis provides evidence of the links between environmental practices spillovers and economic performance.  相似文献

Methodologies to derive price indices for information and communication technology (ICT) products vary between national statistical offices. This may lead to significant differences in measured price changes for these products and there has been concern about the international comparability of volume growth rates of GDP between several OECD countries. This article discusses the possible consequences for measures of economic growth of replacing one set of price indices by another one in the framework of national accounts. It is argued that the issue of ICT deflators cannot be dealt with in isolation and several other factors have to be taken into account, in particular whether ICT products are final or intermediate products, whether they are imported or domestically produced and whether national accounts are set up with fixed or chain weighted index numbers. Overall, results point to modest effects at the aggregate GDP level but may be more significant when it comes to component measures such as volume growth of investment, or of output in a particular industry.  相似文献

This article investigates whether there are Granger causal relationships between broadband penetration, degree of urbanization, foreign direct investment and economic growth using a panel data set covering the G-20 countries for the period 1998–2011. Using our multivariate framework, we first find that all of the variables are cointegrated. Our findings further reveal a network of causal connections between the variables including short-run bidirectional causality between broadband penetration and economic growth among the more developed countries within the G-20. On the other hand, for the developing countries within the G-20, there is evidence of unidirectional causality from economic growth to broadband penetration.  相似文献

Within a theoretical framework, the author analyzes the effects that both workers' remittances and financial intermediation have on economic growth. It is found, among other things, that remittances can have significant positive long-run effects on growth. The author confronts the implications of the theoretical model proposed with panel data for countries in Latin America and the Caribbean. After considering the effect of long-run investment and demographic variables, and controlling for fixed time and country effects, the empirical analysis indicates that financial intermediation tends to increase the responsiveness of growth to remittances. The overall conclusion is that making financial services more generally available should lead to even better use of remittances, thus boosting growth in these countries.  相似文献
