Should government subsidize R&D and does it matter how these subsidies are allocated? We examine these questions in a dynamic
model where R&D is described as sequential sampling from a distribution of new ideas. Successful discoveries affect future
available resources and incentives for further R&D. Consequently, there may be under-investment in R&D. We study the effect
of government interventions aimed at fostering growth through R&D. Calibrating the model with aggregate data from the Israeli
business sector allows us to quantitatively compare two forms of support resembling those actually used to encourage R&D in
the Israeli business sector: (i) an unrestricted subsidy that may be used at the recipients' discretion to finance R&D or
other investments, (ii) a subsidy earmarked by the government for R&D activities only. While there is no theoretical way to
determine which of the two subsidies will have a greater impact on search for new ideas and growth, we find that in the calibrated
economy both subsidies have a significant but similar impact on the economy's output and TFP growth rates. Accordingly, in
the case of the Israeli business sector, the incentives to conduct R&D were sufficiently strong, and no R&D-specific encouragement
was needed. However, a sensitivity analysis reveals that for economies characterized by other parameter values this result
may not be true.

In the mid-nineties FIFA decided to increase from two to three the number of points assigned to the winning team of a soccer
match played under traditional round-robin national leagues. Since a game of soccer can be regarded as a contest, FIFA's measure
provides an interesting case-study for analysing how a change in the system of rewards (from a zero to a non-zero sum rule)
may affect the contestants' equilibrium behaviour. In this paper we try to assess, both theoretically and empirically, whether
FIFA's new point rule has changed soccer towards a more offensive game, in which teams adopt more risky strategies. In particular,
we evaluate the “na?ve hypothesis” according to which the measure would induce every team to play always more offensively,
and we explore the extent to which the change in teams' behaviour may be affected by quality differentials between teams.
Our most important hypothesis is that when the asymmetry between opposing teams is large enough, an increase in the reward
for victory induces the weaker team to play more defensively, rather than the opposite. By looking at a subset of matches
held in the Portuguese first division league, which approximate the conditions of our model, we find support for this hypothesis.

This paper analyses the effects of partially revocable endogenous commitments of a seller in a negotiation with a deadline.
In particular, we examine when commitment is a source of strength, a source of inefficiency and when it does not affect the
bargaining outcome at all. We show that when commitment possesses a minimum amount of irrevocability this crucially determines
the bargaining outcome. In the bilateral bargaining case, commitment becomes a source of inefficiency since it causes a deadline
effect. In the choice of partner framework, however, the deadline effect disappears and there is an immediate agreement and,
moreover, commitment becomes a source of strength since it increases the seller's equilibrium payoff by triggering off competition
between the buyers. 相似文献

The evidence presented in the paper rejects the twin deficit hypothesis for the Austrian current account balance during the
last two decades. The results are based on an estimate of a vector error correction model including quarterly data for the
current account balance and potentially relevant variables driving its dynamics. We compute the variance decomposition of
the current account's forecast error and its generalized impulse responses to shocks in the innovations of the system. The
results in favor of intertemporal expenditure reallocation cannot be reproduced within a second analysis including the current
account and a measure of net output, however. The estimated implicit current account balance, interpreted as the discounted
expected change in future net output, does not follow the actual behaviour of the current account.

This study examines the effect on labour market outcomes, of computer possession at home using longitudinal data collected in Japan. There are positive correlations between computer possession and women's full‐time employment and the salaries of both men and women. In a fixed effects analysis, however, no temporal, causal effects of computer possession on labour market outcomes were found. Overall, the results suggest that the positive correlation between computer possession and better labour market outcomes does not imply causality among workers strongly attached to the labour market. 相似文献

Summary. In this paper I analyze the general equilibrium in a random Walrasian economy. Dependence among agents is introduced in the
form of dependency neighborhoods. Under the uncertainty, an agent may fail to survive due to a meager endowment in a particular
state (direct effect), as well as due to unfavorable equilibrium price system at which the value of the endowment falls short
of the minimum needed for survival (indirect terms-of-trade effect). To illustrate the main result I compute the stochastic
limit of equilibrium price and probability of survival of an agent in a large Cobb-Douglas economy.

在现实市场中,为了方便对酒店进行监督和管理,也为了不同层次消费者的需要,政府往往根据不同的硬件设施标准和软件服务水平对酒店进行等级划分;同时,由于我国旅游市场的外部性因素,政府又根据相应的标准对其进行一定的价格管制, 实行限价,藉此保护消费者,但是这会对消费者和经营者产生影响。 相似文献

The slow and endogenous twist of economic macro-structure makes up an important evolutionary feature of capitalist economies,
and may be at the root of structural crisis. In this line, a Goodwinian growth model with increasing returns and profit-sharing
that tries to picture a simple scenario of the seventies crisis is considered. It is shown that the exhaustion of the Kaldor-Verdoorn
“productivity law” can entail, in a nonlinear framework, a “catastrophic” bifurcation from a “high” to a “low” growth path.
Slow/fast dynamical systems then allow one to formalize a multiple time-scales dynamics where the growth path is shaped by
the structural framework in which it takes place, but has also a long -un feedback. Structural change and crisis appear as
long term and endogenous outcomes. 相似文献

In the last 10–15 years a lot of attempts has been devoted to study the calssical process of convergence of market prices toward natural prices. The two forces that one has thought could achieve this target were capital mobility, that determines the dynamics of output, and demand-supply forces, that determine the dynamics of prices. In this article a model of classical competition is proposed in which a full-cost pricing mechanism is adopted in the rule of evolution of market prices. An asymptotical stability result of long-run equilibrium is proved for a two-commodity model with and without a final demand. 相似文献
