Decomposing and Interpreting Spatial Effects in Spatio-Temporal Analysis: Evidences for Spatial Data Pooled Over Time

2017

Empirical applications using individual spatial data pooled over time usually neglect the fact that such data are not only spatially localized: they are also collected over time, i.e. temporally localized. So far, little effort has been devoted to proposing a global way for dealing with spatial data (cross-section) pooled over time, such as real estate transactions, business start-up, crime and so on. However, the spatial effect, in such a context, can be decomposed in two different components: a multidirectional spatial effect (same time period) and a unidirectional spatial effect (previous time period). Based on real estate literature, this chapter presents different spatio-temporal autor…

A Comprehensive Spatiotemporal Framework for Hedonic Pricing: Integrating the Comparable Sales Approach and Minimizing Spatial Omitted Variable Bias

2019

This paper develops a theoretical and methodological framework that integrates Hedonic Pricing (HP), grid comparable sales approach (CSA), and nearest neighbors into a general spatiotemporal specification. By explicitly providing a theoretical justification for introducing spatial (or spatiotemporal) econometrics to HP, this approach is not only relevant to house price forecasting and automated valuation models (AVM) but also to valuing environmental goods capitalized in housing and to all other fields employing house pricing models. The resulting econometric CSA and spatiotemporal Durbin models provide higher prediction accuracy and reliability to alternatives by reducing the spatially-del…

How to increase company loyalty: using relational variables and sustainable practices to segment the maritime transport sector

2022

Intense competition in goods transportation has highlighted theimportance of understanding customers’interests in order to designsuccessful relationship strategies. This study proposes, through asegmentation approach, to identify customer groups based on theirperceptions of sustainable practices and relational variables abouttheir main transport supplier. From a sample of 122 companies, amultiple correspondence analysis was carried out. The results showthat there are three groups of customer companies, which corres-pond to a high, low, and medium relational and sustainabilityapproach. The identified segments are also significantly different interms of time of operation in the maritime secto…

Critical success factors that contribute to project success

2009

Masteroppgave i økonomi og administrasjon - Universitetet i Agder 2009 This master thesis explores critical success factors that contribute to project success. A pathway to success is presented with nine success factors that are critical in order to achieve project success for oil and gas projects. The critical success factors that are presented are 1) Reservoir complexity, 2) Appraisal strategy, 3) Reservoir front-end loading, 4) Scope and technology, 5) Team integration, 6) Facility front-end loading, 7) Well front-end loading, 8) Target setting and 9) Project execution discipline. I have chosen to have my main focus on two of these success drivers; target setting and project execution di…

2021

Objectives: Inadequate oral hygiene still leads to many serious diseases all over the world. Therefore, this study aimed to analyze scientific research in the field of oral health in order to be able to comprehend their relevant subject areas, research connections, or developments. Methods: This study aimed to assess the global publication output on oral hygiene to create a world map that provides background information on key players, trends, and incentives of research. For this purpose, established bibliometric parameters were combined with state-of-the-art visualization techniques. Results: This study shows the actual key players of research on oral hygiene in high-income economies with …

Mortality and demographic recovery in early post-black death epidemics: Role of recent emigrants in medieval Dijon

2020

International audience; Objective and methodsWe analyze the influence of population movement on susceptibility to death and resilience during two epidemics occurring in Dijon soon after the Black Death. Using a specific program designed to propose links between entries in annual tax registers, we define tentative heads of household, the elapsed time since their first registration and their ties with other persons within the city.ResultsDuring the 1400 epidemic heads of household who were registered for 1–3 years die in large numbers, whereas during years without epidemics, their death rate is lower than that of heads of household who were registered longer. Recent registration is an epidemi…

Intervention and peace*

2018

Abstract Intervention often does not lead to peace, but rather to prolonged conflict. Indeed, we document that it is an important source of prolonged conflicts. We introduce a theoretical model of the balance of power to explain why this should be the case and to analyse how peace can be achieved: either a hot peace between hostile neighbours or the peace of the strong dominating the weak. Non-intervention generally leads to peace after defeat of the weak. Hot peace can be achieved with sufficiently strong outside intervention. The latter is thus optimal if the goal of policy is to prevent the strong from dominating the weak.

Presumption of Innocence and Deterrence

2018

This paper deals with the presumption of innocence and the law enforcer's incentives to exert investigative effort. Our main result is that, even if the presumption of guilt maximizes deterrence for a given effort by the law enforcer, divergent objectives between the law enforcer (who maximizes the probability of a conviction weighted by the magnitude of the sanction and the type of the citizen) and the public decision-maker (who minimizes social costs) may lead the latter to prefer the presumption of innocence. Indeed, the presumption of innocence may induce the law enforcer to increase investigative efforts thereby improving deterrence. As a consequence, if the law enforcer's effort is re…

The Other J.M.: John Maurice Clark and the Keynesian Revolution

2009

This paper suggests that Clark's views regarding the Keynesian Revolution illuminate some of the limitations of the Keynesian orthodoxy that developed after the war, bringing more institutional detail and a greater preoccupation with dynamic analysis. Clark developed the multiplier in dynamic terms and coupled it with the accelerator to provide the framework for business cycle theory. His analysis was not formalized and emphasized time lags and non-linearities, similar to Harrod. In addition, Clark was concerned with the inflationary consequences of Keynesian policies and he was dissatisfied with those mechanical interpretations of the income flow analysis, which came to be known as hydraul…

Sustainability of Pension Systems in the Baltic States

2016

Objective: The objective of the paper is to identify how the concept of sustainability is understood and ensured in the pension systems of Estonia, Latvia and Lithuania; and what implications it brings to the performance of pension schemes. Research Design & Methods: Analysis of various conceptual and methodological approaches to the notion of sustainability of pension systems. Comparative analysis of present pension legislation, as well as preceding stage of pension reforms,   accompanied by a number of numerical models. Findings: The understanding of sustainability is limited by narrow ‘fiscal’ meaning in Latvia, compared to more a multifaceted concept that includes the principle of socia…
