Alternate Measurement Approaches to Recreational Customer Satisfaction: Satisfaction-Only Versus Gap Scores

This study blends service quality and importance-performance methodologies to extend previous research beyond traditional customer service domains. The study examined water-based recreationists' importance and satisfaction ratings across a battery of 19 individual attributes within four domains relevant to outdoor recreation satisfaction (facilities, services, information, and recreation experience). Both the satisfaction-only item scores and gap scores (difference between importance and satisfaction level) were analyzed to determine their relationship within their respective satisfaction domain and with overall satisfaction. The satisfaction-only measures were found to be significantly better indicators than the gap scores of domain-level and overall satisfaction. The items were found to be stronger predictors within the four satisfaction domains than within the overall satisfaction model.     

Using Market Expectations to Test for Speculative Bubbles in the Crude Oil Market

The wide fluctuations of oil prices from 2003 to 2008 have attracted the interest of academics and policymakers. A popular view is that these fluctuations were caused by speculative bubbles due to the increased financialization of oil futures markets. This hypothesis, however, is difficult to examine since the fundamental price of oil is unobservable and, therefore, econometric evidence in favor of bubbles may actually be due to misspecified market fundamentals. In this paper, we extend two recently proposed methodologies for bubble detection that alleviate this problem by using market expectations of future prices. Both methodologies provide no evidence of speculative bubbles.     

On the Rationality of the Post-Announcement Drift

This paper demonstrates that a post-announcement earnings drift, which is often advanced as an example of market irrationality, can arise even if traders act rationally on their information. Specifically, we show that in the presence of share supply variations which are unrelated to information, there is a positive correlation between the unexpected component of current public signals and future price changes. Such a correlation arises from the fact that while prices reveal private information that cannot be found in public signals, non-information based trading distorts the information content of prices relative to the implications of both private and public information. Under these circumstances, markets may appear semi-strong inefficient and slow to respond to earnings announcements even though information is processed in a timely and efficient manner. Our findings correspond well with previously documented empirical evidence and suggest that the robustness of earnings-based anomalies may be rational outcomes of varying uncertain share supply.

Degrees of tax indexation and nominal interest rates: Effects of inflation on incentives to save and invest

This paper examines the effects of inflation expectations on nominal interest rates, and incentives to save and invest under partial and complete tax indexation schemes. One would expect that a partially indexed structure would be better than a non-indexed system. However, this is not the case—it reduces the adverse effects of inflation on the incentives to save, but accentuates them on the incentives to invest. Moreover, a change from a non-indexed tax structure to a fully-indexed structure will, ceteris paribus, lead to lower equilibrium interest rates, whereas a switch to a partially indexed system will imply higher rates.

Can Culture Account for Investment Expectations?

Until recently, risk-taking in investment decisions has been explained by cognitive biases and emotional urges. I would like to propose an alternative explanation, based on the work of Pierre Bourdieu, who links cultural capital to risk-taking. His concept of cultural capital has a very broad meaning, as it encompasses technical skills, aesthetic preferences, verbal facility, general cultural awareness, educational credentials, and artistic competencies. On theoretical grounds, one can assume that a high level of cultural capital enables the taming of uncertainty and allows for temporal horizons that cover longer terms. I test this hypothesis by conducting and analyzing a survey of 307 entrepreneurs. I define risk-taking in two ways: (i) in a somewhat mainstream way, on the basis of expected utility, and (ii) in a heterodox way, in a qualitative, context-dependent setting. I find that, in both cases, there seems to be a link between cultural capital and risk-taking. Furthermore, it seems to make financing issues more salient. I conclude by opening a discussion about the heterogeneity of entrepreneurs and their animal spirits.

Bayesian–Walrasian equilibria: beyond the rational expectations equilibrium

In general rational expectations equilibrium (REE), as introduced in Radner (Econometrica 47:655–678, 1978) in an Arrow–Debreu–McKenzie setting with uncertainty, does not exist. Moreover, it fails to be fully Pareto optimal and incentive compatible and is also not implementable as a perfect Bayesian equilibrium of an extensive form game (Glycopantis et al. in Econ Theory 26:765–791, 2005). The lack of all the above properties is mainly due to the fact that the agents are supposed to predict the equilibrium market clearing price (as agent’s expected maximized utility is conditioned on the information that equilibrium prices reveal), which leads inevitably to the presumption that agents know all the primitives in the economy, i.e., random initial endowments, random utility functions and private information sets. To get around this problematic equilibrium notion, we introduce a new concept called Bayesian–Walrasian equilibrium (BWE) which has Bayesian features. In particular, agents try to predict the market-clearing prices using Bayesian updating and evaluate their consumption in terms of Bayesian price estimates, which are different for each individual. In this framework agents maximize expected utility conditioned on their own private information about the state of nature, subject to a Bayesian estimated budget constraint. Market clearing is not an intrinsic part of the definition of BWE. However, both in the case of perfect foresight and in the case of symmetric information BWE leads to a statewise market clearing; it then becomes an ex post Walrasian equilibrium allocation. This new BWE exists under standard assumptions, in contrast to the REE. In particular, we show that our new BWE exists in the well-known example in Kreps (J Econ Theory 14:32–43, 1977), where REE fails to exist. This work was done in the Spring of 2005, when EJB was a visiting professor at the University of Illinois.
