The paper considers what can be inferred about experimental subjects’ time preferences for consumption from responses to laboratory
tasks involving tradeoffs between sums of money at different dates, if subjects can reschedule consumption spending relative
to income in external capital markets. It distinguishes three approaches identifiable in the literature: the straightforward
view; the separation view; and the censored data view. It shows that none of these is fully satisfactory and discusses the
resulting implications for intertemporal decision-making experiments.

We investigate the interplay between environmental policy, incentives to adoptnew technology, and repercussions on R&D. We study a model where a monopolistic upstream firm engages in R&D and sells advanced
abatement technology to polluting downstream firms. We consider four different timing and commitment regimes of environmental
tax and permit policies: ex post taxation (or issuing permits), interim commitment to a tax rate (a quota of permits) after
observing R&D success but before adoption, and finally two types of ex antecommitment before R&D activity, one with a unique tax rate (quota of permits), the other one with a menu of tax rates (permit
quotas). We study the second best tax and permit policies and rank these with respect to welfare. In particular, we find that
commitment to a menu of tax rate dominates all other policy regimes. 相似文献

The paper analyzes the degree of output persistence in GDP in order toempirically discriminate between the Solow growth model, the perfect competition endogenous growth model and the imperfect competition endogenous growth model for the case of Austria. Wefind that a shock in the growth rate of output induces a permanent and larger effect on the level of GDP. This leads us to refute the Solow growth model and the perfect competition model of endogenous growth.We may not reject the imperfect competition growth model. 相似文献

Certain manuals and computer programs mistakenly identify the mean with the constant in Box-Jenkins time series models. In this paper, it will be shown that (a) the mean and the constant have different values in autoregressive models, and (b) they have an algebraic and graphical relationship. 相似文献

The present paper examines whether there exists a long‐run cointegrating relationship between a stock market index and output and interest rates. Moreover, estimation is conducted over the full sample and both a recursive and rolling sample to examine any time variation in the nature of the relationship. The results support evidence of a single cointegrating vector, where stock prices typically exhibit a positive relationship with industrial production and a negative relationship with interest rates. However, there is significant time variation and periods of time where contrary results are observed. As such any model of stock prices needs to account for such time variation 相似文献

Tests of convergent validity and procedural invariance were used to investigate whether individuals lacking direct experience with a commodity can provide valid responses to contingent-valuation questions eliciting ex post use values. Convergent validity between samples with and without experience was shown to hold for dichotomous-choice responses, but not for open-ended responses. 相似文献
