The existence of a competitive equilibrium for an economy with a measure space of agents is proved by reducing the economy to a three-person game and then applying Debreu's lemma (1952). In addition to the relative simplicity and shortness of the proof, we generalize known results [Aumann (1966), Hildenbrand (1970), Schmeidler (1969)] by allowing both price dependent preferences and satiation.  相似文献

This study provides evidence that a significant percentage of analyst forecast revisions are issued promptly after a broad set of corporate public disclosures and that investors perceive these prompt revisions as more valuable than nonprompt revisions. These results hold for all revisions, revisions outside of the earnings announcement window, or revisions in weeks preceding the earnings announcements and are also robust to various sensitivity tests. Investors particularly value analysts?? prompt interpretation of earnings announcements, Form 8-K filings, or certain qualitative news. To the extent that prompt revisions are more likely to reflect analysts?? information interpretation role, our results suggest that investors value more highly analysts?? ability to interpret public disclosures, especially less structured or non-financial disclosures, than their ability for information discovery.  相似文献

The intertemporal risk-return relation and investor behavior are both important pricing factors that jointly determine the expected market risk premium. Using the price adjustment process as a control variable, we find that the intertemporal risk-return relation is positive conditional on bad market news, but is non-positive conditional on good market news. This implies that good (bad) market news weakens (strengthens) the positive risk-return relation. The pattern in the distortion of the risk-return relation is consistent with short-term mispricing in which investors overvalue (undervalue) the stock market in reaction to good (bad) market news. We also show that ignoring the price adjustment process in the estimation of the risk-return relation leads to model misspecification and induces an upward (downward) bias in estimates of the relative risk aversion parameter conditional on good (bad) news. Our model of the asymmetric risk-return relation along with the price adjustment process is capable of generating the return dynamics that is attributable to technical trading profits. We suggest that the profitability of technical trading rules is not a violation of market efficiency, but a consequence of trading rules exploiting the asymmetric effect of price changes on the risk-return relation, along with the persistence property of price changes.  相似文献

In this article, we draw on the literature on political property rights, political accountability, and strategic management and entrepreneurship to propose a cost neutral reform aimed at promoting long‐run economic prosperity. We propose replacing politicians' defined benefit pensions with a financial contract that is tied to economic performance. In particular, we propose a contract that pays out a lump sum to a politician 30 years after their election if real gross domestic product per capita is above some preset benchmark. Furthermore, we show that the contract can be priced such that it is cost neutral in terms of present value with a defined‐benefit pension. We argue that this contract provides a net benefit to society. (JEL D70, D72)  相似文献

Pets factor into the daily decision-making of many people. Importantly, various characteristics of these human–animal relationships are known to strongly influence pet owners’ risk behaviour and, consequently, their animals’ welfare during disasters. Yet, few studies have examined a range of such characteristics concurrently in order to describe risk propensity differences in these relationships. In this study, 437 Australian companion-animal (pet) owners reported human–animal relational, personality and attitudinal characteristics, to examine differences in stated tendency to act to secure their pet’s welfare whilst risking potential harm in a hypothetical disaster dilemma. Cluster analysis identified five archetypal profiles differing in relational, personality, attitude and risk-propensity characteristics, as well as in stated willingness to risk personal safety for the well-being of a pet. Results suggest that relational archetypes are an effective means of examining pet–owner risk propensity, to better understand owners’ risk-taking to protect their animals from harm during a disaster.  相似文献

There is a small but growing literature on the determinants of economic freedom. This paper contributes to this literature in two ways. First, it is empirically shown that β-convergence in economic freedom occurred from 1980 to 2010. Countries with low levels of economic freedom in 1980 “catch up” at a rate of 0.7 percent a year on average, ceteris paribus. Second, the structural characteristics that contribute to this institutional convergence are documented. Conditional convergence estimates suggest democratic institutions do not con- tribute to conditional convergence. Exitability, a variable that captures how easy it is for citizens to “vote with their feet” is related to the change in economic freedom from 1980 to 2010 in a statistically significant manner across all specifications. This provides some preliminary evidence as to the importance of “exit” versus “voice” with respect to the question of institutional change.  相似文献

In assessing the usefulness of the analysts’ stock picking advice, the extant literature has largely focused on the profitability of either their stock recommendations or target prices in isolation. In this paper, we examine the profitability of investment strategies that exploit the information analysts convey through revisions in both their stock recommendations and target prices. We find that these strategies significantly outperform the comparable strategies that make use of only one analyst output.  相似文献

Despite existing evidence suggesting that financial inclusion enhances consumers' welfare, there has been no attempt to examine the link between financial inclusion and financial vulnerability, measured along multiple dimensions. We computed more comprehensive indices of financial vulnerability and financial inclusion using polychoric principal component analysis based on a nationally representative financial inclusion survey in South Africa. Results from quantile regressions show that only the top 20% of the financially included had lower vulnerability but the effect was weaker among the more vulnerable categories. Also, the decline in financial vulnerability was less pronounced when financial inclusion was narrowly defined by excluding quality indicators. These findings suggest that financial inclusion is benefitting a few consumers in South Africa which points to the need for a bottom-up approach in designing financial products that improve the welfare of the financially included consumers.  相似文献

Accounting concepts dictate that separately disclosed components should contain separate useful information. This paper examines the relations between income statement components and analysts' earnings forecasts and forecast errors. Regressions explaining earnings forecasts using earnings components provide a better fit than regression using just aggregate income to explain forecasts. We interpret this as consistent with the hypothesis that analysts use incremental information in components not available in aggregate income. However, additional tests based on predictability of forecast errors indicate that analysts do not incorporate all information available in components into earnings forecasts. In addition, this inefficiency appears to increase at longer forecast horizons.  相似文献
