This article attempts to provide a structure-functional analysis of economic activity and propositions based on this analysis about applications of gaming-simulation for an institutionalist study of the functioning of economic systems. Modern institutionalism in contrast to neoclassical economics, which is to a great extent mathematicized, does not actually use any quantitative methods and models. Simulation games represent such models that can be designed and promote the implementation of research in the spirit of neoinstitutional economics. In this sense, gaming-simulation may be considered as institutional modeling. In this work we shall, first be concerned with a ‘static’ structure of economic activity deriving from the three-level scheme by Parsons. Next, a ‘dynamic’ structure of economic activity will be analyzed in terms of the concept of limited rationality by Simon. In the final section, we characterize the methods of reflection of different components of economic systems in gaming simulation models, as well as ways of implementing the research on such models. 相似文献

This article evaluates the impact of consumer choice programs, price caps, and sliding scale plans on consumer prices of gas
using a custom survey of public service commissions and data from the Department of Energy. A seemingly unrelated regressions
model estimates residential, commercial and industrial prices jointly, controlling for potentially endogenous demand. Consumer
choice programs are estimated to lower residential and commercial prices significantly, by bringing competition to markets
with smaller consumers. Prices fall even before deregulation as utilities build consumer loyalty and fight competition. Sliding
scale plans are estimated to lower prices of small consumers while raising industrial prices. Price caps lead to overall higher
prices, with unclear ranking across consumer classes.

A drawdown constraint forces the current wealth to remain above a given function of its maximum to date. We consider the portfolio optimisation problem of maximising the long-term growth rate of the expected utility of wealth subject to a drawdown constraint, as in the original setup of Grossman and Zhou (Math. Finance 3:241–276, 1993). We work in an abstract semimartingale financial market model with a general class of utility functions and drawdown constraints. We solve the problem by showing that it is in fact equivalent to an unconstrained problem with a suitably modified utility function. Both the value function and the optimal investment policy for the drawdown problem are given explicitly in terms of their counterparts in the unconstrained problem. 相似文献

AbstractThe paper investigates how language facilitates communication process between government and business. We use Russian context to show barriers and challenges of using language in official communication between governmental authorities and Russian companies. In our work, we demonstrate how language may produce employee’s misunderstanding and discuss typical sources of ineffective usage of language. The results indicate that problematic issues of both linguistic and non-linguistic nature can lead to serious implications for successful communication between government and business in Russia. We found that documentations’ complexity, which is perceived as such due to a complicated subject area they belong to (legal, tax, etc.) and language insufficiency applied are most likely to raise multiple problems related to government’s communication with business. 相似文献

We prove the existence of arbitrary (resp., semicontinuous, continuous) utility representations for arbitrary (resp., semicontinuous, continuous) preorders satisfying some weakened Debreu order separability conditions. In this way we widely generalize a classical result for total preorders that essentially is due to Debreu. 相似文献

In this article, the authors update and confirm the findings of a 2005 article that was the first to view corporate underwriter choices as the outcome of a two‐sided matching process in which issuers look to the abilities of the underwriters offering their services and underwriters focus on the quality of the issuers that wish to use their services. This view offers a contrast with both the conventional representation of issuer‐underwriter associations as one‐sided decisions (by either issuers or underwriters) and the classical economist's representation of a competitive market in which prices serve as the primary market‐clearing mechanism. In their examination of both initial public offerings (IPOs) and seasoned equity offerings (SEOs) during the period 1980–2010, the authors continue to find strong evidence that higher‐quality issuers associate with more reputable underwriters and lower‐quality issuers match with lower reputation underwriters. Moreover, when examining cases of underwriter switching between an IPO and SEOs by the same issuer, they find that cases involving the largest divergence in the relative rankings of issuer and underwriter were the most likely to produce a change of underwriter—and that issuers that experienced larger post‐ IPO increases in quality were more likely to find more reputable underwriters for their SEOs (than for their IPOs). The authors also find that the larger the number of offerings brought to market in a given year, the smaller the market share of the top‐tier underwriters, likely reflecting the willingness of the most reputable underwriters to turn down business to maintain quality and reputation. Finally, the most reputable underwriters appear to benefit from the fact that the issuers whose IPOs they underwrite end up raising larger amounts of capital, both at the time of the IPO and in the larger and more frequent seasoned offerings by such issuers that come after the IPO. This evidence in support of two‐sided matching suggests that, especially for high‐quality issuers, the reputation of the underwriters they contract with for security offerings is likely to be more important than the underwriting fees they incur. What's more, the authors' finding that the most reputable underwriters are less likely to lose high‐quality clients and have more stable market share—and that the higher‐quality issuers they attract end up raising larger amounts of capital over their lives as public companies—suggests that underwriters' investments in building and preserving their reputations have a large expected payoff. 相似文献

Only five populations have achieved maximum life expectancy (or best practice population) more than occasionally since 1900. The aim of this article is to understand how maximum life expectancy is achieved in the context of mortality transition. We explore this aim using the concepts of potential life expectancy, based on minimum rates at each age among all high longevity populations, and concordant ages. Concordant ages are defined as ages at which the minimum death rate occurs in the population with the maximum life expectancy. The results show the extent to which maximum life expectancy could increase through the realization of demonstrably achievable minimum rates. Concordant ages are concentrated at increasingly older ages over time, but they have produced more than half of the change in maximum life expectancy in almost all periods since 1900. This finding is attributed to their quantity and position whereby concordant ages are concentrated at the ages that have the greatest impact on mortality decline in a particular period. Based on mortality forecasts, we expect that concordant ages will continue to lead increases in female maximum life expectancy, but that they will play a weaker role in male maximum life expectancy. 相似文献

The decline in output volatility in Germany is analysed. A lower level of variance in an autoregressive model of output growth can be either due to a change in the structure of the economy (a change in the propagation mechanism) or a reduced error term variance (reduced impulses). In Germany the decline output volatility is due to a decline in the persistence of the growth process. This is in contrast to the US results, where a break in the variance seems to dominate the decline in persistence. A change in the conduct of monetary policy (the establishment of another monetary policy regime) could be part of an explanation for the change in propagation. Stochastic simulations with a New Keynesian DSGE model support the hypothesis. 相似文献
