This paper begins with a look at both optimization modeling and discrete-event simulation modeling, and explores how they can most effectively work together to create additional analytic value. It then considers two examples of a combined optimization and simulation approach and discusses the resulting benefits.

This paper provides recommendations for circumventing memory problems and reducing execution times for your mixed-modeling analyses, as well as showing the new HPMIXED procedure can be beneficial for certain situations, as with large sparse mixed models.

This paper provides a high-level tour of five modern approaches to model building that are available in recent releases of SAS/STAT.

This paper provides an example that shows you how to use multiple RANDOM statements in PROC NLMIXED to fit nested nonlinear mixed models, and it provides details about the computation that is involved in fitting these models.

It's all about the context here in this particular AITA. Dad had saved money for his son's college fund, which ultimately didn't end up getting used, because his son decided to drop out. Fast forward, and the son is asking his dad if he could tap into the college fund for what sounds like newlywed expenses/alleviating debt. Dad was not about it, because the whole point of the money was for it to be used for college.

Statement from Risaburo Nezu, Chairman of the OECD Steel Committee, Paris, 6 June 2014

The future sustainability of health systems will depend on how well governments are able to anticipate and respond to efficiency and quality of care challenges. Bold action is required, as well as willingness to test innovative care delivery approaches. This book examines the whole new world of possibilities in using mobiles and the Internet to address healthcare challenges.

OECD recommands to France to modernise and better govern labour migration

In a new report, the OECD says that France should modernise and strengthen the co-ordination of labour immigration in order to attract foreign talent and align itself more closely with the needs of the labour market.

Competitiveness and carbon leakage issues have been some of the main concerns in the implementation and discussions of climate policies. This paper examines the macroeconomic and sectoral competitiveness and carbon leakage impacts associated with a range of stylised mitigation policy scenarios.

This document provides a detailed technical description of the ENV-Linkages model. The OECD ENV-Linkages Computable General Equilibrium (CGE) model is an economic model that describes how economic activities are inter-linked across several macroeconomic sectors and regions. It links economic activity to environmental pressure, specifically to emissions of greenhouse gases (GHGs).

This paper presents a framework to include feedbacks from climate impacts on the economy in integrated assessment models. The proposed framework uses a production function approach, which links climate impacts to key variables and parameters used in the specification of economic activity. The paper pays particular attention to the challenges of distinguishing between damages and the costs of adapting to climate change.

Southeast Asia’s over-reliance on natural resources like oil, gas, minerals and wood for economic growth is unsustainable over the long term and is causing environmental damage that will hurt future prosperity if left unchecked, according to a new OECD report.

Current carbon prices are falling short of the levels needed to reduce greenhouse gas emissions driving climate change, but even moderate price increases could have a significant impact, according to new OECD research.

This paper describes MOLES 1.0, an integrated land-use and transport model developed with Object-Oriented Programming principles in order to combine selected characteristics from Spatial Computable General Equilibrium and microsimulation models. MOLES 1.0 models the links between urban land use, mobility patterns, urban economic activities and their environmental impacts, in particular air pollution and emissions of greenhouse gases.

This paper reviews the existing literature on modelling the macroeconomic consequences of the transition to a circular economy. It provides insights into the current state of the art on modelling policies to improve resource efficiency and the transition to a circular economy by examining 24 modelling-based assessments of a circular economy transition.

The Czech economy is thriving, with robust employment, expanding exports and falling government debt. Efforts should now focus on boosting workforce skills and innovation to improve labour supply and productivity, further reduce poverty and inequality, and green the economy, according to two new OECD reports.

The purpose of this study is to investigate the effect of congestion pricing on the demand for clean transport modes. It draws on an empirical analysis of the effect of Milan’s congestion charge on the use of bike sharing. The analysis indicates that congestion pricing increases daily bike-sharing use by at least 5% in the short term.

The Latvian economy is thriving, with strong job growth driving convergence with more advanced economies. Efforts should now focus on reducing inequality, responding to the challenges posed by population ageing and making growth stronger, inclusive and greener, according to two new OECD reports.

New business models can help reduce environmental pollution, optimise the use of natural resources, increase productivity and energy efficiency, and provide a new source of economic growth. The development of new business models is also affected by a range of barriers, many of which can be addressed by well-designed policies.

Although the market for green goods and services is growing, the development of new business models is affected by a range of barriers, many of which can be addressed by well-designed policies.

Southeast Asia’s over-reliance on natural resources like oil, gas, minerals and wood for economic growth is unsustainable over the long term and is causing environmental damage that will hurt future prosperity if left unchecked, according to a new OECD report.

This report develops an analytical framework that assesses the macroeconomic, environmental and distributional consequences of energy subsidy reforms. The framework is applied to the case of Indonesia to study the consequences in this country of a gradual phase out of all energy consumption subsidies between 2012 and 2020.

Current carbon prices are falling short of the levels needed to reduce greenhouse gas emissions driving climate change, but even moderate price increases could have a significant impact, according to new OECD research.
