On a clear day you might see an environmental Kuznets curve 总被引:1,自引:0,他引:1
We shed some new light on the Environmental Kuznets curve (EKC) and show how it can be viewed as a particular form of equilibrium
relationship, where technology and preference parameters determine the shape of the curve. In contrast to most of the literature
on the EKC, we estimate a theoretically consistent model on long-run data (Swedish sulfur emission, covering the period 1900–2002).
Furthermore, we test and date structural change. The model suggests four regimes, 1900–1918, 1919–1933, 1934–1967 and 1968–2002,
generating four rather different patterns for pollution over time. The policy-conclusions are consonant with Pearce’s general
view about the EKC: there is no theoretical presumption that it has an inverted U shape, nor should any country try to “grow
out of the environmental problems” without analyzing the benefits and costs of so doing. 相似文献

We study Austrian job reallocation in the period of 1978 to 1998, using a large administrative dataset where we correct for spurious entries and exits of firms. We find that on average 9 out of 100 randomly selected jobs were created within the last year, and that about 9 out of randomly selected 100 jobs were destroyed within the next year. Hence, the magnitude of Austrian job flows seems to be comparable to other countries, similar to the well-known results of Davis et al. (1996) for the United States. Job reallocation appears to be driven primarily by idiosyncratic shocks. However, job creation increases significantly during cyclical upswings whereas job destruction rises in downturns. We also find substantial persistence of job creation and destruction. The pronounced pattern of job reallocation rates falling with firm size and age continues to hold when we use a set of controls. Finally, we show that – controlling for sector and firm size composition – Austrian job reallocation rates are only half the rates for the U.S. This result is not surprising given the impact of tighter regulation and labor law in Austria. 相似文献

Green net national product was thought to be one way of measuring sustainable income. However, David Pearce understood that
a better measure of sustainable development was to look at what a generation is leaving in form of capital assets to later
generations. In this article, his arguments and insights are highlighted against recent theoretical advances. 相似文献

The dynamic behavior of a simple macroeconomic disequilibrium model is analyzed in which consumers' changes in money holdings constitute the dynamic link between any two periods. It is shown that, under constant government consumption, a constant production function (no investment), and fixed prices and wages, stationary states of Keynesian unemployment are stable whereas those of repressed inflation are globally unstable. Possibilities of unemployment and output cycles are indicated for fixed wages as well as for some very simple class of wage and price adjustment mechanisms. 相似文献

We analyse the state of the art in the field of life cycle portfolio choice, a recent strand of the literature on intertemporal
portfolio selection. Life cycle models are designed to identify optimal savings and portfolio policies over the lifetime of
investors. They can help to improve pension schemes by showing how these could be specifically tailored to the individual
employee’s circumstances to overcome the ‘one-size-fits-all’ philosophy still prevailing in parts of the mandatory retirement
savings system. To facilitate comparison, we first describe set-up, solution method and characteristic results for a basic
model and then derive a general framework to classify existing contributions. We highlight the models’ strengths and weaknesses
and assess their ability to resolve existing portfolio puzzles. Lessons from the literature are summarized and promising areas
for further research identified.

It is well known that dropping variables in regression analysis decreases the variance of the least squares (LS) estimator of the remaining parameters. However, after elimination estimates of these parameters are biased, if the full model is correct. In his recent paper, Boscher (1991) showed that the LS-estimator in the special case of a mean shift model (cf. Cook and Weisberg, 1982) which assumes no “outliers” can be considered in the framework of a linear regression model where some variables are deleted. He derived conditions under which this estimator outperforms the LS-estimator of the full model in terms of the mean squared error (MSE)-matrix criterion. We demonstrate that this approach can be extended to the general set-up of dropping variables. Necessary and sufficient conditions for the MSE-matrix superiority of the LS-estimator in the reduced model over that in the full model are derived. We also provide a uniformly most powerful F-statistic for testing the MSE-improvement. 相似文献
