We take advantage of repeated cross‐sectional household surveys and a sharp discontinuity created by the introduction of an unconditional cash transfer to elders in Bolivia, to evaluate its impact on educational expenditures on children within a household. We find positive and significant impacts of the program at the aggregate level. We also find that the program has stronger effects on indigenous populations as well as on female and rural populations. Our results are robust to a series of falsification tests, survey structure, model specification, and estimation methods.  相似文献

This paper proposes a semiparametric smooth coefficient cost model to study the university cost structure where coefficients are an unknown function of the university's overall quality. A local least square method with a kernel weight function is used to estimate the cost function, and a simple statistic for testing a parametric model of the additive quality versus the semiparametric smooth coefficient model is applied. Empirical results from 56 universities in Taiwan show that, taking quality into account, higher education is subject to diseconomies of scale. In all categories—comprehensive and science/technology and public and private universities—the current university scale in Taiwan is too big to be cost efficient. (JEL I21, H52, 9120)  相似文献

This paper contains three subjects. First, an extension of Mokken's nonparametric item response models from dichotomous items to items with two or more ordered answer categories is proposed. Second, a computer program to analyze multicategory item scores is presented. This program is called MSP. The analyses by means of MSP are based on the multicategory extension of Mokken's theory. Finally, an application of MSP to empirical multicategory test data is presented in order to illuminate its possibilities.  相似文献

For much of the 20th century the dominant view in macroeconomics was that cross-border finance needed to be regulated in order to balance the ‘impossible trinity’ first sketched by John Maynard Keynes in his two books on monetary theory. The dominant view in development economics during the same period was that cross-border capital flows need to be regulated for similar reasons but also to mobilize domestic resources for economic development. The view that capital mobility was something to be constrained fell out of favor in mainstream economics by the 1980s and 1990s. The experience of numerous financial crises in the past 20 years has spawned new economic theories that reintroduce the notion that cross-border finance can cause financial instability. One strand of new theory in this realm picks up from Ragnar Nurkse, Hyman Minsky, and others, and has become popular in many emerging market capitals and in the United Nations system. Another strand of new theory comes from modern welfare economics and is gaining ground in mainstream economics, central banks, and the Bretton Woods institutions. This paper examines these new breakthroughs and traces them to their origins in economic thought. Coupled with new econometric evidence on the efficacy of capital account regulation, the regulation of capital flows is justified now more than ever.  相似文献

This paper estimates structural vector autoregression models of output, the real exchange rate and trade balance for the group of seven leading advanced economies (G‐7). Unlike previous studies, we do not impose long‐run purchasing power parity as an identifying assumption; instead, the shocks underlying the model are structurally identified using a set of theory‐consistent sign restrictions. Empirical results show that nominal shocks account for most of the long‐run variability in trade balances across the G‐7 countries. We are able to attribute this finding to long‐run movements in the real exchange rate, as the real exchange rate is significantly affected by nominal shocks in the long run.  相似文献

Water's role in manufacturing technologies has received limited attention. A KLEM model of the sector's technology is extended to include two facets of water use: intake and recirculation. Three annual cross-sectional surveys on plant-level water use are pooled and combined with census data to estimate this extended model for the Canadian manufacturing sector over the period 1981–1991. While Canada's water allocation regulations influence private water withdrawals, statistical tests support representing water intake as a variable input. Water intake is found to be a substitute for water recirculation, energy, labour and capital. The relationship between water intake and recirculation is stronger when water intake is process-related rather than related to cooling and steam production. Technological change has been biased in the direction of increased water intake and decreased water recirculation.  相似文献

The classic way of performing a market forecast for industrial products implies an econometric analysis of the historical data of consumption and their projections into the future. The present work illustrates a fresh approach to the problem; the demand for the product under study is evaluated in a mathematical model which takes into consideration the technological and commercial characteristics of this product and correlates it with competitive and substitutive products. Competitiveness is measured by assigning merit scores to the characteristics of the different products, and calculating the relevant “weights of importance” on the basis of the historical consumptions. Forecasts of consumption are made by estimating the future scores of the characteristics and extrapolating the weights of importance. An example of complete application of the model to the textile market in Italy is included.  相似文献

This article analyses the relationship between investment and savings for Angola using the Feldstein–Horioka puzzle, with monthly data from January 2000 to December 2013. Integer and fractional integration and cointegration techniques are employed to investigate the relationship between investment and savings. Several regression specifications are employed, concluding that the Feldstein–Horioka puzzle is not validated for the Angolan economy. Policy implications are derived.  相似文献
