What Can We Learn From Random Walks on Input-Output Tables

What Can We Learn From Random Walks on Input-Output Tables

In this post we elaborate on the insights we can derive when using well established Environmentally-Extended Input-Output frameworks in a slightly different manner, as the canvas for monetary random walks "following the money"

Reading Time: 20 min.

Summary

We imagine the random propagation of money flows through simplified economic networks as a sequence of monetary transactions following a stochastic process. We follow the journey of a cash amount. Whenever a transaction in this chain implies an environmental impact, that impact is recorded and cumulated. Computing the expected outcome of such flows reproduces the standard results of environmentally extended input-output models. The random walk interpretation allows the computation of various additional statistical properties, one example being estimating a variance of environmental impact or intrinsic uncertainty around the central estimate. We interpret this uncertainty as being a concentration risk measure.

Representing Matrices as JSON Objects: Part 2 - Sparse Matrices

Representing Matrices as JSON Objects: Part 2 - Sparse Matrices

Representing a Sparse Matrix as a JSON object is a task that appears in many modern data science contexts. While there is no universally agreed way to achieve this task, in this post we discuss a number of options and the associated tradeoffs.

Reading Time: 11 min.

Recap of Part 1 of the Matrix-to-JSON Post Series

In the first installment of this series, Part 1 we discussed the motivation behind representing and serializing matrices as JSON objects. We defined relevant concepts and in particular the concept of unrolling the matrix into a one-dimensional array and the notion of Column and Row Major orders. We outlined some use cases of interest and initiated a benchmarking exercise that looks into various R and Python JSON serialization utilities (available at the matrix2json repository).

Towards a Faceted Taxonomy of Financial Services

Towards a Faceted Taxonomy of Financial Services

In this post we are after a flexible financial services taxonomy that can help us understand both existing and evolving financial system developments. To this end we examine a range of existing classification systems and synthesize the salient requirements.

Who Needs a New Financial Services Taxonomy?

Our age is increasingly dominated by the dual challenges and opportunities of the sustainability transition on the one hand, and digital transformation on the other. We witness emerging new financial domains with novel names such as Fintech , or TechFin, or various combinations and hues of Green and Sustainable in Sustainable Finance and we see forces that are reshaping the direction of travel for the financial industry.

What are ActivityPub Networks?

ActivityPub is a technical specification towards decentralized (more precisely, federated) social networking (termed the Fediverse) based upon the exchange of ActivityStreams messages that follow the Activity Vocabulary. The ActivityPub proposal has been standardized and published by the W3C and has motivated the design of several federated social networking systems.

Electrifying the Doughnut: Simplified Visions of Sustainable Finance

Reading Time: 30 min.

June 21 2023 marks the sixth annual #ShowYourStripes Day - a time when meteorologists and other climate communicators around the world raise awareness of our warming planet by displaying colorful visuals of climate change. The warming stripe graphics are representations of the change in temperature over the past 100+ years (here we use the global average). Each stripe represents the temperature averaged over a year. The stripes typically start around the year 1900 and finish in 2022.

Equinox 0.7 release focuses on scope 2 (electricity) emissions

Equinox 0.7 release focuses on scope 2 (electricity) emissions

New data models introduced in this release of Equinox cater to the requirement of integrating energy attribute certificate information into the portfolio database.

Reading Time: 3 min.

GHG Accounting offers a means of measuring the direct and indirect emissions to the Earth’s Biosphere of CO2 and its equivalent gases from industrial and other activities. GHG Accounting is a rapidly developing area that has come to receive increased focus in the context of accelerating Climate Change. Given that the generation of electricity and heat accounts for around a third of global GHG emissions electricity consumers have incentives to proactively reduce those emissions by reducing electricity demand, or by shifting energy supply by procuring alternative lower-carbon or renewable resources.

Mathematical Representations of Credit Portfolio Data

Mathematical Representations of Credit Portfolio Data

What do we mean by credit data? This post is a discussion around mathematical terminology and concepts that are useful in the context of working with credit data, taking us from network graph representations of credit systems to commonly used reference data sets

Reading Time: 1 min.

Course Objective

Digging into the meaning of credit data collections, the logic that binds them together towards understanding what they can be used for and what limitations and issues they may be affected by, this new course in the Credit Portfolio Management category explores a new angle to look at an old practice.

First public release of the Solstice simulation framework

First public release of the Solstice simulation framework

Solstice is a flexible open source economic network simulator. Its primary outcomes are quantitative analyses of the behavior of economic systems under uncertainty. In this post we provide a first overall description of Solstice to accompany the first public release.

Modeling economic networks and their dynamics

Economic networks are the primary abstractions though which we can conceptualize the state (condition) and evolution of economic interactions. This simply reflects the fact that human economies are quite fundamentally systems of interacting actors (or nodes in a network) with transient or more permanent relations between them.

White Paper: Deep Linking Financial and Energy Accounting

White Paper: Deep Linking Financial and Energy Accounting

We develop a conceptual framework for integrated accounting that imposes on certain non-financial disclosures the same double-entry balance constraints that apply to conventional financial statements. We identify the key ingredients required for a rigorous multidimensional accounting framework in terms of concepts, postulates and design choices, and we illustrate these ideas with a worked-out example of linking financial and energy accounts.

Reading Time: 9 min.

Integrated Energy Accounting is keeping track and reporting on an entity’s detailed energy footprint (primary inputs, transformations and waste generation) not as an addendum to financial accounting and reporting but as a deeply-linked extension that is subject to the same level of rigor.

How Open Data and Open Source can support Green Public Procurement - Part 4

How Open Data and Open Source can support Green Public Procurement - Part 4

In the fourth part of this series we approach Green Public Procurement as a Sustainable Portfolio Management task and explore how open data can support this mission

Reading Time: 9 min.

Introduction

In this fourth and final installment we will discuss how the data framework we have developed thus far can be mapped into classic portfolio management concepts and categories, and thus, how one can articulate the concept of sustainable procurement management on a portfolio basis. The concepts and analytic methodologies of financial portfolio management1 can significantly enhance the toolkit available to practitioners and, in sense, connects the domain of Green Public Procurement to other ongoing initiatives in broader Sustainable Finance.
