数理统计是一门以概率论为理论基础,研究随机现象统计规律性的数学学科。在经济全球化和信息化的今天,经济、管理等学科领域越来越侧重数理统计的应用,尤其是在大数据时代下,统计数据浩如烟海,数理统计的地位就更加凸显。随着社会的发展,推断统计已经取代传统的描述统计,成为现代统计的核心,而抽样分布作为统计推断的开篇内容,同时也是连结概率论与数理统计的桥梁,因此在统计推断中占据重要地位。本文主要对统计推断中常用的抽样分布及其应用作总结,并结合例题对统计量的抽样分布作出合理地判别。  相似文献

Abstract This is an attempt to tell a coherent story of a possible path towards an algorithmic revolution in economic theory, based on foundational debates in mathematics. First, by exposing the non‐computational content of classical mathematics, and its foundations, it is shown that both set theory and the tertium non datur can be dispensed with, as foundational concepts. Next, then, as a natural sequel, it follows that every kind of economic theory that bases its theoretical underpinning on classical mathematics can be freed from these foundations and can be made naturally algorithmic. This will make the subject face, in an all pervasive way, absolutely (algorithmically) undecidable decision problems. The thrust of the path towards an algorithmic revolution in economics lies, then, in pointing out that only a radically new mathematical vision of microeconomics, macroeconomics, behavioural economics, game theory, dynamical systems theory and probability theory can lead us towards making economic theory a meaningfully applied science and free of mysticism and subjectivism.  相似文献

In this paper we address a long standing gap in economic theory—the gap between claims for the dynamic efficiency of trading in markets, and the findings of formal economic theory, which justify those claims only under restrictive assumptions. We use agent-based methods to study the dynamics of exchange with trading agents who are characterized by several different preference relations. We see that outcomes converge with high probability to Pareto optima in the cases studied, including the well-known example due to Scarf.  相似文献

This study analyzes how an economic recession affects entrepreneurship from a qualitative perspective. We define entrepreneur as a person who takes risks under uncertainty. Based on this definition, an entrepreneur's exit decision is modeled using real options theory to measure entrepreneur's willingness to accept uncertainty. We find that entrepreneurs who entered before a recession exit when their critical revenue stream reaches 0.16 times the average revenue stream value. The equivalent value for entrepreneurs who enter during an economic recession is 0.33 times the average revenue stream. Furthermore, when uncertainty doubles, the exit probability of entrepreneurs who enter during an economic recession is approximately 2.75 times higher than that of entrepreneurs who enter before recession. We conclude that the majority of entrepreneurs who enter during an economic recession are qualitatively disadvantaged, which leads to the overall decrease in qualitative entrepreneurship.

A decision theory model is presented where the decision to start a firm is assumed to be a rational economic decision of a utility maximizer. The model is tested using data for business births in 82 Mississippi counties over the period 1979-1987. Results of the aggregated model are encouraging but suggest that the alternative to a risky venture is not riskless wage labour. Rather, wage labour also carries a risk which is important in determining whether to start a business. The results indicate that there is a strong economic motivation in entrepreneurial ventures which must be considered in addition to psychological factors. The model suggests that encouragement of entrepreneurial ventures can be based upon lowering thc costs of start-ups and policies that increase the probability of success.  相似文献

The article analyzes the relation between transformations in information systems and changing forms of organization. Drawing on a historical case study, it examines the rise of actuarial theory in Germany and Switzerland around 1900 and its significance for the emergence of the first modern social insurances. So far, the history of actuarial theory has been written as the social history of the actuarial profession or the epistemic history of probability calculus. By examining the political and economic contexts of the history of actuarial theory, the article also discusses the notion of an “insurance society”. The argument concludes that Foucauldian interpretations of actuarial theory as a technology of power and a condition of modern governmentality are too monistic and should be specified. The article suggests to use the concept of a “technology of trust” to interpret the integrative power of actuarial theory in a political field marked by deep antagonisms.  相似文献

ABSTRACT The work of Rene Thom relating to catastrophe theory has influenced probability theory Since so much of the research conducted by social scientists depends on calculating the probability that events will occur, an introduction to catastrophe theory is needed By discussing the social implications of the position outlined by Thom, social scientists will better understand the difficulties associated with generating probability statements  相似文献

Standard real business cycle models are often unable to replicate three empirical facts: positive output in response to good news, stochastic volatility of macro variables, and asymmetric business cycles. This paper proposes a unified basis for understanding these facts in a tractable dynamic stochastic general equilibrium (DSGE) model, in which the key is the interaction of information flows and disaster risk. Information flows fluctuate between two regimes with different precision levels for signals regarding future economic fundamentals. A shift in forecast precision changes the probability of entering an economic disaster. High disaster risk leads to low expected capital returns and a decline in hours, investment, and output. Changing information structures results in different volatility and skewness over the business cycle. Simple theory makes the two expectation effects through information flows and disaster risk transparent. Quantitatively, the model suggests that the interaction of the two expectation effects plays a significant role in accounting for the higher-order moments of the business cycle.  相似文献
