Expertise in chess

This chapter provides an overview of research into chess expertise. After an historical background and a brief description of the game and the rating system, it discusses the information processes enabling players to choose good moves, and in particular the trade-offs between knowledge and search. Other topics include blindfold chess, talent, and the role of deliberate practice and tournament experience

The age of reason: financial decisions over the lifecycle

The sophistication of financial decisions varies with age: middle-aged adults borrow at lower interest rates and pay fewer fees compared to both younger and older adults. We document this pattern in ten financial markets. The measured effects cannot be explained by observed risk characteristics. The sophistication of financial choices peaks around age 53 in our cross-sectional data. Our results are consistent with the hypothesis that financial sophistication rises and then falls with age, although the patterns that we observe represent a mix of age effects and cohort effects.Financial institutions ; Loans

The Age of Reason: Financial Decisions Over the Lifecycle

In cross-sectional data sets from ten credit markets, we find that middle-aged adults borrow at lower interest rates and pay fewer fees relative to younger and older adults. Fee and interest payments are minimized around age 53. The measured effects are not explained by observed risk characteristics. We discuss several leading factors that may contribute to these effects, including age-related changes in experience and cognitive function, selection effects, and cohort effects.

The Elderly Centre Location Problem

© The Operational Research Society 2020. This is an Accepted Manuscript of an article published by Taylor & Francis in Journal of the Operational Research Society on 12 Feb 2020, available online: https://doi.org/10.1080/01605682.2020.1718020.Increased human life expectancy combined with declining birth rates around the globe has led to ageing populations, particularly in the developed world. This phenomenon brings about increased dependency ratios and calls for setting new policies for the elderly citizens. This comprises the provision of a set of life-enhancing services in an accessible and equitable way. In this paper, we consider a multi-period problem of locating senior centres offering these services to the elderly population against budget constraints and capacity limitations. We assume that the attractiveness of facilities to elderlies is inversely proportional with the travel time to access these facilities. Both consistent and inconsistent versions of the problem are considered, aiming at identifying the set of facilities to operate in each region at each period, the service type(s) to be offered and the allocation of budget in each period to location and operation of facilities. A mixed integer mathematical programming model is presented, an efficient iterated local search procedure is proposed and managerial insights are provided.Peer reviewedFinal Accepted Versio
