Summary. When players are unable to write complete state contingent contracts it is shown, within the context of a non-cooperative
contracting-renegotiation game, that the only subgame perfect equilibrium allocations are those that correspond to the set
of first-best allocations. Players are able to implement this set of allocations by signing an initial contract that is subsequently
renegotiated in all states of the world. The contracting-renegotiation problem is complicated in an interesting way by assuming
that the state space is continuous. The issue of the existence of an initial contract, that is subsequently renegotiated to
the set of first-best allocations, must be resolved. Unlike Aghion, Dewatripont and Rey [1994], the results here do not require
nor depend upon the comonotonicity of the objective functions.

This paper examines the convergence of payoffs and strategies in Erev and Roth's model of reinforcement learning. When all players use this rule it eliminates iteratively dominated strategies and in two-person constant-sum games average payoffs converge to the value of the game. Strategies converge in constant-sum games with unique equilibria if they are pure or if they are mixed and the game is 2×2. The long-run behaviour of the learning rule is governed by equations related to Maynard Smith's version of the replicator dynamic. Properties of the learning rule against general opponents are also studied. 相似文献

In this paper we examine a number of issues that arise in investigating labor force dynamics using the Spanish Labor Force
Survey (EPA). These issues are by no means specific to the Spanish case and apply to most European-style labor force surveys.
Our main conclusions may be summarized as follows. First, survey nonresponse cannot be neglected. Second, the EPA tends to
underestimate employment and participation of high-educated young people, and to overestimate those of the low-educated elderly.
Finally, we find little evidence that attrition causes important selection biases in estimating quarterly transition probabilities. 相似文献

Overlapping generations model of fiat money yields an infinity of competitive equilibrium solutions, only one of which is stationary. Economies reported in this paper involved a sequence of overlapping generations of three or four individuals; each individual lived for two periods. In their young age individuals were endowed with chips that could be traded for fiat money wish the individuals of the old generation. In their old age, individuals could exchange their units o flat money for the consumption good. Results of the experiments exhibit some support for the stationary solution. The results are robust to two designs of exchange institutions (double oral auctior and supply schedule auction) and to two different endogenous ways of converting money into chips at the end of the game (average price prevailing during the last period the game is actually played and the average price forecast made during the last period the game is actually played).A preliminary version of this paper was presented at the meeting of the Economic Science Association and at the Federal Reserve Bank of Minneapolis. The authors are grateful for comments received from various participants at both presentations. Financial support was provided by the McKnight Foundation, the Honeywell Foundation, National Science Foundation (SES 89-12552), and Richard. M. and Margaret Cyert Family Funds. 相似文献

We consider the problem of a commonly owned technology which transforms a single input into a single output. We are interested
in implementing a social choice rule called theproportional solution. We introduce a mechanism which implements the proportional solution in Nash, strong (Nash) and undominated Nash equilibria.
In the mechanism each agent announces only two numbers which can be interpreted as the total output and her share of the total
input-output combination.
This paper was originally titled "Doubly implementing the proportional solution." I would like to thank my advisor William
Thomson for his detailed comments and suggestions. I would also like to thank Jeffrey Banks and Sung-Whee Shin for their comments.
Two anonymous referees and an editor’s comments improved this paper substantially. 相似文献

Competition For Order Flow, Market Quality, And Price Discovery In The Nasdaq 100 Index Tracking Stock 总被引:1,自引:0,他引:1
We investigate competition for order flow, market quality, and price discovery in the Nasdaq 100 Index Tracking Stock (QQQ). The QQQ, an AMEX‐listed, exchange‐traded fund, is the most actively traded security in the U.S. equities market. On July 31, 2001, the NYSE began trading the QQQ, marking the first time it traded securities of companies it does not list. The greatest volume of trading takes place on electronic communication networks (ECNs), following by trading on the AMEX and the NYSE. Most of the block trades are executed on the AMEX, where the bid‐ask spreads are narrower. We find that ECNs contribute the most to the price‐discovery process. The spreads on all trading platforms have decreased and market quality and price discovery have improved since QQQ shares have traded on the NYSE. 相似文献

In this paper we investigate the efficiency of a class of transaction-generating algorithms, originally suggested in Bollerslev and Domowitz (1993). Our comparison utilizes real transaction data recorded over Reuters D2000-2 electronic broking system for 7 h in June 1993 and transaction data generated from FXFX quotations over an identical period. Results suggest that, at this high-frequency data sampling, the performance of these transaction-generating algorithms is poor, with the most likely explanation of this outcome due to the high-frequency characteristics of FXFX spreads and quotation intensity. 相似文献
