It is shown that the demand revealing mechanism creates only a negligibly small undesired deficit, when the number of participants in the decision group in question is sufficiently large. Since the size of deficit is a measure of inefficiency and since the former is inevitable, the states result demonstrates the approximate optimality of the mechanism. 相似文献

R&D, Investment, and Industry Dynamics 总被引:1,自引:0,他引:1
We present a model of industry evolution where the dynamics are driven by a process of endogenous innovations followed by subsequent embodiments in physical capital. Traditionally, the only distinction between R&D and physical investment was one of labeling: the first process accumulates an intangible stock, knowledge, while the second accumulates physical capital. Both stocks affect output in a symmetric fashion. We argue that the story is not that simple, and that there is more to it than differences in the object of accumulation. Our model stresses the causal relationship between past R&D expenditures and current investments in machinery and equipment. This causality pattern, which is supported by the data, also explains the observed higher volatility of physical investment relative to that of R&D expenditures. 相似文献

In an insurance context, the discounted sum of losses within a finite or infinite time period can be described as a randomly weighted sum of a sequence of independent random variables. These independent random variables represent the amounts of losses in successive development years, while the weights represent the stochastic discount factors. In this paper, we investigate the problem of approximating the tail probability of this weighted sum in the case when the losses have Pareto-like distributions and the discount factors are mutually dependent. We also give some simulation results. 相似文献

In this paper nonlinear structures in German bank stock returns are investigated in a stochastic modelling framework. In the first step we show the existence of a nonlinear return structure by means of the McLeod-Li and the BDS test. In the second step we focus our analysis on the kinds of nonlinearity actually present in bank stock data. On the basis of the Hsieh test it is possible to discriminate with high power additive from multiplicative dependencies to provide guidance for the choice of an adequate class of stochastic models. It is shown that the multiplicative dependencies predominating the bank stock returns can be captured by low order GARCH models. 相似文献

One of the major features of structural adjustment is an attemptto reallocate laborand hence outputthrough changesin relative prices. This article assesses how price changesaffect the working patterns of young people in rural Côted'Ivoire. The analysis is based on a model of the labor supplyof rural households and on the construction of composite priceindexes. The data come from the Côte d'Ivoire Living StandardsSurvey for 1985 and 1986. The panel aspect of the data allowsthe work choice made in one year to depend on the individual'schoice in the previous year. Results indicate that the priceof agricultural output generally is a positive incentive onthe decision to participate in the labor force. However, thisresult depends heavily on the employment and education of theindividual in the previous period. Those not already workingare less likely to respond to favorable movements in the pricesof cash crops by entering the work force. 相似文献

We investigate the determinants of changes in U.S. interest rate swap spreads using a model that explicitly allows for volatility interactions between swaps of different terms to maturity. Changes in the swap spread are found to be positively related to interest rate volatility, to changes in the default risk premium in the corporate bond market, and to changes in the liquidity premium for government securities. Swap spread changes are negatively related to changes in the level of interest rates and changes in the slope of the term structure. We also find that there is a strong and significant volatility interaction among spreads for swaps of different maturities and that the process for the conditional variance of the spread is highly persistent across all maturities. 相似文献

In this Forecast Release we compare the likely outcomes of the economic policies proposed by the three main contenders in the General Election. The results of some Dolicies. such as Labour's import controh and exchannge controls and the Allianie incomes policy, aie particularly dificult to evaluate using a conventional model; even for Conservative policies which are similar to those pursued so far, there remains considerable uncertainty about their consequences in future years. We have therefore prepared two forecasts for each of the three parties. One of these forecasts assumes that their policies are broadly successful, the other assumes they are unsuccessful. 相似文献
