Many different measures of Tobin's q have been proposed which differ in measurement methods and data sources. This paper evaluates the similarities and differences in the statistical properties of the different measures using ARIMA and factor analysis methods. The statistical properties of average and marginal q measures are found to be quite different. 相似文献

We analyze the contribution of ecosystem services to GDP and use this contribution to calculate an empirical price for ecosystem services. Net primary production is used as a proxy for ecosystem services and, along with capital and labor, is used to estimate a Cobb Douglas production function from an international panel. A positive output elasticity for net primary production probably measures both marketed and nonmarketed contributions of ecosystems services. The production function is used to calculate the marginal product of net primary production, which is the shadow price for ecosystem services. The shadow price generally is greatest for developed nations, which have larger technical scalars and use less net primary production per unit output. The rate of technical substitution indicates that the quantity of capital needed to replace a unit of net primary production tends to increase with economic development, and this rate of replacement may ultimately constrain economic growth. 相似文献

Counterfactual experiments with the Reserve Bank of New Zealand's core model provide some insight into the implications for New Zealand's economic performance over the 1990s, had it credibly fixed its currency to the Australian dollar. If New Zealand had faced the relatively more stimulatory Australian monetary conditions prevailing over the 1990s, then output growth may have been temporarily boosted. However, demand pressures would have probably been greater and inflation higher. In particular, results suggest that over the latter part of the 1990s annual inflation would have been approximately 1% point higher on average. Stochastic simulation experiments provide a vehicle to analyse what the implications of currency union might be more generally. Results suggest that if New Zealand were to lose its ability to set monetary policy independent of that set in Australia, then the variability of inflation and output would increase over the business cycle. 相似文献

This paper is directed at the following question: given an incomplete set of price data relating to goods or services in some category of output for each of a number of different countries, what arithmetic should be performed on the prices to get a meaningful representation of the relative category price-levels of the countries? In the course of developing an answer to the question, some broader matters are considered and illuminated. A comparison of category price-levels for different countries is analogous to a commonly-encountered problem in many areas, that of ranking ordinally or cardinally in one dimension a group of “entities”—persons, households, firms, industries, etc.—on the basis of sets of measurements associated with the individual entities. It is this point of view which dominates the following presentation. 相似文献

Summary. We develop a method of assigning unique prices to derivative securities, including options, in the continuous-time finance model developed in Raimondo (2001). In contrast with the martingale method of valuing options, which cannot distinguish among infinitely many possible option pricing processes for a given underlying securities price process when markets are dynamically incomplete, our option prices are uniquely determined in equilibrium in closed form as a function of the underlying economic data.Received: 14 April 2003, Revised: 7 January 2004, JEL Classification Numbers:

Past studies of hospital rate setting regulation conclude that mature programs have been effective in constraining hospital expenditures. However, if rate regulation is influenced by higher hospital expenditures the relationship between expenditures and rate setting is confounded. This study assesses the impact of rate setting on hospital and non-hospital expenditures using a simultaneous-equation model which separates the effects of hospital expenditures on the decision to regulate from the effects of regulation on expenditures. The simultaneous-equation results indicate that mature rate setting is associated with lower per capita health care expenditures, including hospital and non-hospital expenditures. 相似文献
