We “extend” standard arguments for greening the product side of the national accounts to the income side of the accounts and turn up an anomaly. For an economy with oil use, no entry for oil income, a supposed primary factor, appears in the income side of the national accounts when the depletion of natural capital is accounted for on the product side of the accounts. We resolve this issue by applying an income definition developed in the theory of national accounting. This, however, leads to another anomaly on the income side of the national accounts.  相似文献

Repeated dichotomous choice contingent valuation data are generated from responses to a succession of binary questions regarding alternative prices for an environmental good. In this paper we propose a simultaneous equation model that allows for endogeneity and error correlation across the responses at each stage of the bidding process. The model allows us to study the evolution of anchoring effects after the second dichotomous choice question. Estimation involves the Bayesian techniques of Gibbs sampling and data augmentation, and the application focuses on the preservation value of a natural area. The results for a data set involving up to four successive dichotomous choice questions show that restricted multiple-bounded models are rejected by the data with the general model. In addition, willingness to pay tends to stabilize after the second stage in the elicitation process for the general unrestricted model. When taking anchoring effects into consideration, it is revealed that individuals’ responses in the latter stages are influenced by the sequence of bid prices offered in earlier questions. Nevertheless, they do not have a significant effect on welfare estimates.   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

Whether ENSO has affected U.S. macroeconomic performance has been a matter of dispute. To address the issue we explore whether there has been any co-cyclicality of ENSO fluctuations and the rates of inflation and economic growth over the 1894-1999 timespan and, failing this, whether aperiodic ENSO shocks have had any impact on these variables. Neither co-cyclicality nor aperiodic shocks are discernible. While ENSO may briefly influence the performance of particular sectors of the economy in particular regions, as documented by the previous literature, such locally-important effects vanish into the noise surrounding macroeconomic trends in an economy as large and complex as that of the U.S.  相似文献

Enduring rents     
Rent seeking is often studied with reference to a contemporaneous rent evaluated at a point in time. We study the social cost of rent seeking when rents endure over time, but may have to be re-contested because of imperfect rent protection, or may disappear because of deregulation. The present value of a contested rent measures the social cost of rent seeking, irrespective of imperfect rent protection and the prospect of deregulation. Rent seeking is discouraged by the inability of governments to commit to protect rents and by their inability to commit to rent-generating regulations and policies. Moreover, lasting deregulation can preempt a substantial fraction of the potential rent seeking cost.  相似文献

In this paper we estimate a standard version of the New Keynesian Monetary (NKM) model augmented with term structure in order to analyze two issues. First, we analyze the effect of introducing an explicit term structure channel in the NKM model on the estimated parameter values of the model, with special emphasis on the interest rate smoothing parameter using data for the Eurozone. Second, we study the ability of the model to reproduce some stylized facts such as highly persistent dynamics, the weak comovement between economic activity and inflation, and the positive, strong comovement between interest rates observed in actual Eurozone data. The Sect. 3 implemented is a classical structural method based on the indirect inference principle. We are grateful to Eduardo Ley, two anonymous referees and seminar participants at the XXXI Simposio de Análisis Económico (Oviedo, Spain) and Bank of Spain for their useful comments.

Abstract.  This paper analyzes the consequences of tourism in rural and urban areas on regional incomes, welfare and urban unemployment using a generalized Harris Todaro model. In this model two urban and two rural goods are produced. A distinguishing characteristic of this model is that the urban non-traded good is not consumed in the rural region and, similarly, the rural non-traded good is not consumed in the urban region. The most important result we obtain is that a tourist boom in the urban region may immiserize the rural area. Hence the welfare interests of rural and urban consumers may be in conflict as a result of tourist expansion in the urban region.  相似文献

The paper analyzes the intertemporal relationship between oil duties, taxes, government spending, and GDP in Mexico during the 1981–98 period. The results from estimating a VAR model, impulse response functions, and variance decompositions on the quarterly series of taxes, government spending, oil duties, and GDP suggest that there seems to be a substitution effect between oil duties and tax revenues, and that tax revenues are not able to absorb temporary decreases in oil duties. Also, increases in tax revenue might lead to increasing government spending, but short–run increases in government spending are not likely to lead to political pressure to reduce the expected budget deficit via increased taxation and/or oil revenues. Lastly, GDP is not stimulated in the short–run by temporary increases in government spending and, thus, stabilization measures adopted in recent years to reduce the size of the government are not likely to significantly undermine GDP growth.  相似文献

Single or double bounded contingent valuation? A Bayesian test   总被引:2,自引:0,他引:2  
This paper evaluates the performance of asymptotic approximations of the Bayes factor to appraise the relative likelihoods of the bivariate and the restricted double bounded models for contingent valuation. The performance of the Bayes factor test is studied by Monte Carlo simulation showing that it correctly chooses the bivariate model when appropriate, but tends to over predict the double bounded model when the correlation coefficient is not estimated accurately. However, the quadratic error in estimating willingness to pay is reduced if the model preferred by the test is chosen. In addition, we consider the effect of averaging the estimates of WTP from both models, weighting each model with its posterior probability. The results show that ‘model averaging’ across the competing hypothesis further reduces the squared error. The applications with two data sets on National Parks show that the test rejects the restricted double bounded hypotheses against the bivariate model.  相似文献
