The resolution of uncertainty communicates information through negative entropy, which increases fitness. This setup can be generalized. Information turns out to be the link between diversity of types in populations and unfolding environmental patterns in time. Conditioning of information over multiple levels reduces uncertainty, which increases fitness. While previous research has applied this logic to temporal patterns through Kelly’s bet-hedging criteria (stochastic switching), this article shows how the same logic can also be applied to multilevel population structures. Examples include taxonomies and geographic distributions. The result is a reformulation of fitness as a multilevel communication process between the evolving population and its environment. The multilevel recursion provides a single setup to investigate diversity relations between any population hierarchy and environmental patterns. Information theoretic optimization through bet-hedging reveals that fitness can be optimized for the case in which there is one specialized type per environmental state. This is reminiscent of the notion of requisite variety, and shows how fitness optimization can be understood in terms of a multilevel informational fit between the evolving population and environmental patterns.","PeriodicalId":400873,"journal":{"name":"Microeconomics: Information","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122354615","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, we evaluate each player’s offense and defense in the SPM framework based on three basic categories of skills: scoring, rebounding, and ball-handling. We then simulate games using the skill ratings of the ten players on the court. The results of the simulations measure the effectiveness of individual players as well as the 5-player lineup, so we can then calculate the synergies of each NBA team by comparing their 5-player lineup’s effectiveness to the “sum-of-the-parts.” We find that these synergies can be large and meaningful. Because skills have different synergies with other skills, our framework predicts that a player’s value is dependent on the other nine players on the court. Therefore, the desirability of a free agent depends on the players currently on the roster. Indeed, our framework is able to generate mutually beneficial trades between teams. Other ratings systems cannot generate mutually beneficial trades since one player is always rated above another. We find more than two hundred mutually beneficial trades between NBA teams, situations where the skills of the traded players fit better on their trading partner’s team.","PeriodicalId":400873,"journal":{"name":"Microeconomics: Information","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115583372","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Castilla","doi":"10.2139/ssrn.1996882","DOIUrl":"https://doi.org/10.2139/ssrn.1996882","url":null,"abstract":"I present a simple model of intra-household allocation between spouses to show that when the quantity of resources available to the household is not perfectly observed by both spouses, hiding of income can occur even when revelation of the additional resources increases bargaining power. From the model, a test to identify income hiding empirically is derived. For the empirical application, a household survey conducted in Southern Ghana is used. I exploit the variation in the degree of asymmetric information between spouses, measured as the difference between the husband’s own reporting of farm sales and the wife’s reporting of his farm sales, to test whether the allocation of resources is consistent with hiding. For identification, the wife’s clan and the husband’s bride-wealth payments upon marriage are used as instruments for asymmetric information. My findings indicate that allocations are suggestive of men hiding farm sales income in the form of gifts to extended family members, which are not closely monitored. It is unclear whether hiding has negative consequences in the long run because hiding occurs in the form of gifts, instead of expenditure in alcohol or tobacco. If the gifts represent a form of risk-sharing, then these gifts will return to the household in the future, and hiding is not necessarily inefficient. However, if these gifts are motivated by social pressure then hiding can result on poverty traps caused by kin system. The wife’s response is also suggestive of hiding. As information asymmetries increase, she reduces her expenditure in non-essential items, such as prepared foods and oil, but increases personal spending. Expenditure in oil is one of the main sources of calories among poor households in the region.","PeriodicalId":400873,"journal":{"name":"Microeconomics: Information","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129065864","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
