Modern national income accounting was designed in the early 20th century for the purpose of providing improved indicators about the performance of the economy so that government policy makers could better control the economy. The way that performance is measured affects the types of policies used to try to accomplish policy goals. Two attributes of national income accounting are analyzed for their effects on economic policy. First, government production is included in the national income accounts at cost, rather than at market value as private sector output is measured. This biases policy toward a larger public sector. Second, output is measured as a homogeneous dollar amount. This biases policy toward focusing on increasing quantities of inputs and outputs in the production process, rather than on innovation and entrepreneurship, which are the true engines of economic progress. Economic policy could be improved by focusing less on national income as an indicator of policy, and more on the underlying processes that foster economic progress. 相似文献

Agriculture remains sensitive to variation in rainfall and temperature. Fortunately, our ability to predict the lower frequency variation in the earth's atmosphere is increasing rapidly. While information cannot affect the underlying source of variability, it allows unexpected shocks to be anticipated and acted upon. This paper develops and analyzes an intertemporal Ricardian trade model with Bayesian beliefs. Results in this paper show that improved climate prediction reduces expected prices, but increases price variability. In addition, trade is crucial to realizing the potential benefits of climate prediction. The value of climate prediction is highest with both storage and trade, and falls by over 300% when a country is in autarky. 相似文献

Scarf (Int. Econ. Rev. 1 (1960) 157) proposed a model of dynamic adjustment in which the standard tatonnement price adjustment process orbits around, rather than converges to, the competitive equilibrium. Hirota (Int. Econ. Rev. 22 (1981) 461) characterized the price paths. We explore the predictions of Scarf's model in a non-tatonnement experimental double auction. The average transaction prices in each period do follow the path predicted by the Scarf and Hirota models. When the model predicts convergence the data converge; when the model predicts orbits, the data orbit in the direction predicted by the model. Moreover, we observe a weak tendency for prices within a period to follow the path predicted by the model. 相似文献

Tort reform of the motor accident insurance compensation scheme in the Australian state of New South Wales in 1999 came about as a result of an untested experiment in regulatory negotiation. This article is a first-hand account of the successful attempt to craft a consensual modification of the scheme through deliberations among a working group of service provider representatives. The author, a Canadian lawyer, investigated the prospects for change, acted as chief negotiator, and observed the legislative process that led to the final law reform. 相似文献

A subclass of monotonic transferable utility (T.U.) games is studied: average monotonic games. These games are totally balanced. We prove that the core coincides with both the bargaining set à la Davis and Maschler and the bargaining set à la Mas-Colell. To obtain this result a technique based on reduced games is used.

This paper deals with on-line computation—or step-wise learning—of Pareto optimal insurance contracts. Our approach tolerates that the loss distribution might be unknown, intractable, or not well specified. Thus we accommodate fairly inexperienced parties. Losses are here simulated or observed, one at a time, and they cause iterated revisions of the premium. The mechanical and global nature of probability calculus thereby yields to more tentative, myopic procedures, possibly closer to how humans operate or reason in face of risk. Sequential revisions may also reduce the expense of insurers' time and money in seeking sufficient statistics. Emphasized below is the remarkable simplicity and stability of the resulting adaptive procedures. Special attention goes to catastrophic risks, and to subsidized or competitive insurance. 相似文献

Capacity planning and resource allocation are crucial to the cost-effective delivery of health care services. In this paper, we present an analytic approach based on a modified version of the Holt-Winters multiplicative seasonality forecasting model to determine the frequency distribution associated with a hospital care unit's census. This paper is a follow-up to the census frequency distribution simulation model described in Lapierre et al. (Socio Econ. Plan. Sci. 33 (1999) 25). We demonstrate that our model can provide census frequency distributions equivalent to the simulation model of Lapierre et al. [1], but without the computational effort common to simulation models. 相似文献

This paper revisits the relationship between a country’s openness and its per capita income. Building on Frankel and Romer,
it argues that a dynamic econometric specification similar to the ones used in empirical growth studies better fits the theoretical
literature and also resolves some otherwise unresolved inconsistencies. The preferred econometric method is Blundell and Bond’s
system-GMM estimator, which allows dealing with measurement error, weak instruments, and time-invariant country-specific effects.
The findings confirm the existence of a strong effect of trade on income but fail to find evidence for trade as an independent
factor of divergence.
