We study a two‐period general equilibrium model with incomplete asset markets and default. We make collateral endogenous by allowing each seller of assets to fix the level of collateral. Sellers are required to provide collateral whose first‐period value, per unit of asset, exceeds the asset price by an arbitrarily small amount. Moreover, borrowers are also required to be fully covered by the purchase, in the first period, of state‐by‐state default insurance. These insurance contracts are offered by lenders. The insurance cost or revenue is a linear charge and plays the role of a spread penalizing borrowers who will incur in default and benefiting lenders who will suffer default. Under these assumptions, equilibrium always exists. 相似文献

We prove the existence of monotonic pure strategy equilibrium for many kinds of asymmetric auctions with n bidders and unitary demands, interdependent values and independent types. The assumptions require monotonicity only in the own bidder's type. The payments can be a function of all bids. Thus, we provide a new equilibrium existence result for asymmetrical double auctions and a small number of bidders. The generality of our setting requires the use of special tie-breaking rules. We present an example of a double auction with interdependent values where all equilibria are trivial, that is, they have zero probability of trade. This is related to Akerlof's “market for lemmons” example and to the “winner's curse,” establishing a connection between them. However, we are able to provide sufficient conditions for non-trivial equilibrium existence. 相似文献

In Portugal the EEC membership represented a major change in Portuguese Administration functioning. This article uses the new institutionalism approach and the concept of path-dependence to analyse the change in the functioning of a central directorate reponsible for industrial policy. It argues that despite the external pressures for change has altered the directorate operations, there are patterns of continuity which are path-dependent. The response to change shows institutional reproduction in traditional features which is partly due to the reluctance to change traditional methods and partly because of the routines, procedures and norms embedded in the culture. 相似文献

Repeated Dichotomous Choice Formats for Elicitation of Willingness to Pay:
Simultaneous Estimation and Anchoring Effect 总被引:1,自引:1,他引:0
Repeated dichotomous choice contingent valuation data are generated from responses to a succession of binary questions regarding
alternative prices for an environmental good. In this paper we propose a simultaneous equation model that allows for endogeneity
and error correlation across the responses at each stage of the bidding process. The model allows us to study the evolution
of anchoring effects after the second dichotomous choice question. Estimation involves the Bayesian techniques of Gibbs sampling
and data augmentation, and the application focuses on the preservation value of a natural area. The results for a data set
involving up to four successive dichotomous choice questions show that restricted multiple-bounded models are rejected by
the data with the general model. In addition, willingness to pay tends to stabilize after the second stage in the elicitation
process for the general unrestricted model. When taking anchoring effects into consideration, it is revealed that individuals’
responses in the latter stages are influenced by the sequence of bid prices offered in earlier questions. Nevertheless, they
do not have a significant effect on welfare estimates.

This paper studies a class of one-dimensional screening problems where the agent's utility function does not satisfy the Spence-Mirrlees condition (SMC). The strength of the SMC for hidden information problems is to provide a full characterization of implementable contracts using only the local incentive compatibility (IC) constraints. These constraints are equivalent to the monotonicity of the decision variable with respect to the agent's unobservable one-dimensional parameter. When the SMC is violated the local IC constraints are no longer sufficient for implementability and additional (global) IC constraints have to be taken into account. In particular, implementable decisions may not be monotonic and discretely pooled types must have the same marginal utility of the decision (or equivalently, get the same marginal tariff). Moreover, at the optimal decision, the principal must preserve the same trade-off between rent extraction and allocative distortion measured in the agent's marginal rent unit. In a specific setting where non-monotone contracts may be optimal we fully characterize the solution. 相似文献

This paper seeks to provide the services sector with a focus on the assessment of quality and for this purpose, a technique that may able a quantitative approach to evaluating quality is proposed. The use of the fuzzy sets theory to process data was used, thus allowing a more flexible and suitable insight into the characteristics of the service sector. An extension of the technique for order performance by similarity to the ideal solution was used. This informs managers of the distance from the company $\prime $ s current level of quality, if compared to a company of perfect quality by means of an overall evaluation. The same technique was used to detect changes in the level of quality during the period surveyed by using a stratified assessment. Finally, a practical application of the approach proposed is presented. 相似文献

The diversity of approaches to customer relationship management (CRM) brings about the need for systematic reviews. The objective of this article is to identify and categorize the most used publications in the CRM field. We conducted a bibliometric analysis using the Web of Science database. To identify and categorize the subfields, we conducted an exploratory factor analysis. The most used publications were categorized into: (1) methodology in the CRM research field; (2) relationship marketing; (3) service quality and customer loyalty; (4) implications of market-oriented strategy; (5) CRM theory and its practical implications; (6) strategic management; and (7) customer value. 相似文献

INFINITE HORIZON INCOMPLETE MARKETS WITH A CONTINUUM OF STATES 总被引:1,自引:0,他引:1
In this paper we address existence of equilibria in an incomplete markets economy with countably many periods and a continuum of states at each node of the infinite tree. We consider two models: one where agents have to honor their commitments and another where default is allowed. In both models, marginal utility of income, at each node, is shown to be bounded, and we prove existence by taking finite-dimensional approximations and applying Fatou's lemma sequentially. 相似文献

ABSTRACTAn accurate assessment of inflation expectations is crucial for the management of monetary policies. However, expectations are not directly observed and are hence normally inferred either from the interest rate structure or from surveys of professional forecasters. Alternatively, a direct measure may be obtained from consumer surveys. The aim of this paper is to study the formation of inflation expectations in Brazil, using a novel dataset based on the FGV/IBRE consumer survey. Basing our model on the rational inattention hypothesis, we find that individual heterogeneity plays a very significant role in shaping individual expectations; also, Brazilians adjust expectations to current inflation and to a fixed reference value, while professional forecasts do not play a very relevant role. 相似文献
