Modern data analysis has given birth to numerous grouping constructs and programming paradigms, way beyond the traditional group by. Applications such as data warehousing, web log analysis, streams monitoring and social networks understanding necessitated the use of data cubes, grouping variables, windows and MapReduce. In this paper we review the associated set (ASSET) concept and discuss its ...

This article explores the relationship between the job characteristics underlying the Goldthorpe model of social class (work monitoring difficulty and human asset specificity) and those underlying theories of technological change (routine and analytical tasks) highlighted as key drivers for growing inequality. Analysis of the 2012 British Skills and Employment Survey demonstrate monitoring diff...

We study the informational efficiency of a market with a single traded asset. The price initially differs from the fundamental value, about which the agents have noisy private information (which is, on average, correct). A fraction of traders revise their price expectations in each period. The price at which the asset is traded is public information. The agents’ expectations have an adaptive co...

Intellectual property (IP) rights differ from ordinary property rights. Historically, societies have tolerated monopolistic inefficiency from IP protection to incentivize intellectual asset creation. This paper considers how competitive markets can optimally allocate resources, bypassing that monopolistic inefficiency. It departs from earlier related work in three ways: First, it allows economi...

Several frictions restrict the government’s ability to tax assets. First of all, it is very costly to monitor trades on international asset markets. Moreover, agents can resort to non-observable low-return assets such as cash, gold or foreign currencies if taxes on observable assets become too high. This paper shows that limitations in asset observability have important consequences for the tax...

This study attends to equivocal results regarding the relationship between equity control and international joint venture (IJV) performance by proposing a transaction-cost-based contingency framework. We examined the moderating effects of asset specificity and uncertainty on the relationship between foreign parent equity control and IJV survival in an empirical setting of Japanese IJVs in 12 As...

INTRODUCTION The global science system stands at a critical juncture. On the one hand, it is overwhelmed by a hidden avalanche of ephemeral bits that are central components of modern research and of the emerging ‘cyberinfrastructure’4 for e-Science.5 The rational management and exploitation of this cascade of digital assets offers boundless opportunities for research and applications. On the ot...

This paper presents a possible explanation for some of the empirical properties of asset returns within a heterogeneous-agents framework. The model turns out, even if we assume the input fundamental value follows an simple Gaussian distribution lacking both fat tails and volatility dependence, these features can show up in the time series of asset returns. In this model, the profit comparison a...
