This paper describes a test of the null hypothesis that the first K autocorrelations of a covariance stationary time series are zero in the presence of statistical dependence. The test is based on the Box–Pierce Q statistic with bootstrap-based P-values. The bootstrap is implemented using a double blocks-of-blocks procedure with prewhitening. The finite sample performance of the bootstrap Q test is investigated by simulation. In our experiments, the performance is satisfactory for samples of n=500. At this sample size, the differences between the empirical and nominal rejection probabilities are essentially eliminated. 相似文献

Transaction utility effects when quality is uncertain 总被引:1,自引:0,他引:1

The existing literature finds that price discrepancy, which represents the difference between expected and observed price,
helps explain brand choice and purchase intention. This effect is often attributed to transaction utility, that is, the incremental
utility associated with the surprise of observing a price lower or higher than expected. This research considers the possibility,
however, that transaction utility is a less important determinant of choice when quality is uncertain. We propose and find
that acquisition utility (perceived value for the money) tends to dominate the explanation of purchase intention, but transaction
utility is significant only when consumers are more certain about quality. Our discussion considers the relative role of transaction
utility in explaining consumer decision making and how the informative and allocative roles of price might be distinguished.

The tax sensitivity of foreign direct investment (FDI) has importantpolicy implications. If FDI is not responsive to taxation, thenit may be an appropriate target for taxation by the host country.This question is examined for Mexico by estimating the responseof FDI from retained earnings and transfers from abroad to thetax regimes in Mexico and the home country, the credit statusof multinationals, country risk factors, and regulatory andtrade regimes in Mexico. FDI in Mexico is found to be sensitiveto the tax regimes in Mexico and the United States, the creditstatus of multinationals, country credit ratings, and the regulatoryenvironment. Thus Mexico's current policies to dismantle regulationsand employ a tax system competitive with the United States areexpected to have salutory effects on FDI in Mexico. 相似文献

An expected-utility maximizer, obliged to make a single purchase from two alternatives, finds that a queue forms for the good that would have been selected had both goods been available. An M/M/1 queue is posited and for each period of delay the maximum additional payment that the consumer would incur to join the queue is determined. This has implications for saving. Not only the availability of the good, but also the delay in obtaining it, the alteration in its arrival rate, and the “stampede effect” determine saving behavior. 相似文献

This paper examines the role of inflation in financing the American Civil War, and the effects of that inflation on the level of real wages in the North. A wage determination model is specified in which the equilibrium real wage is determined by real forces and the money wage is allowed to adjust to its equilibrium value with lags. Econometric estimates of the model support Wesley Clair Mitchell's contention that wage movements lagged price movements during the war. Comparison of the estimated equilibrium money wage and the estimated current money wage makes it possible to assess the magnitude and importance of the wartime redistribution of income attributable to inflation. 相似文献
