Complexity Modelling in Economics: the State of the Art | Economic Thought

Nada novo neste artigo publicado no Economic Thought. Faz uma descrição básica do tema complexidade e propõe modelos baseados em agente. Não direciona porém qual modelo atualmente publicado seria um melhor ponto de partida (K+S?). Vale a leitura mais como uma primeira aproximação ao tema para quem ainda não embarcou.

Complexity Modelling in Economics: the State of the ArtBruna Bruno, Marisa Faggini, Anna ParzialeAbstractThe economic crisis happening across the world over the last few years describes a range of interdependencies and interactions,and has highlighted the fundamentalf laws of neoclassical economic theory: its unedifying focus on prediction and, above all, its inability to explain how the economy really works. As such, it is increasingly recognised that economic phenomena cannot be exclusively investigated as being derived from deterministic, predictable and mechanistic dynamics. Instead, a new approach is required by which history-dependence, organic and ever-evolving processes are also accounted for. As this view implies new challenges and opportunities for policy, we will focus our attention on innovative components of Complexity Theory for the study of economics and the evaluation of public policies.

A base evolucionista do consumo

 

Muitas vezes sinto falta de abordagens do lado do consumo, especialmente sobre a motivação de compra. Este livro do Saad, comentado no artigo abaixo, trabalha este ponto através da psicologia aplicada na economia. Vai para a lista de leitura.

Over the last three to four decades, the social sciences have been subject to increasing examination under an evolutionary framework. Leading the charge into consumer and marketing theory has been Gad Saad, a pioneer of evolutionary consumer psychology who was responsible for the first evolutionary psychology papers to appear in any consumer and marketing journals.

Problemas da economia moderna

Bom artigo sobre metodologia e crise na teoria econômica atual.

economics needs to take advantage of other methods of enquiry used in other social sciences, such as case studies, oral histories, archival research, ethnographies and other qualitative approaches to supplement and to better inform economic theorizing and policymaking.

Valor das árvores nas cidades

Trabalho interessante de avaliação de serviços ambientais, que teve alguma repercussão na imprensa de fora. Gerou números grandes (BILHÕES) para chamar a atenção para o problema, com uma sugestão de política de aumento da cobertura árborea nas cidades, mesmo que seja com a motivação maior de aumento de valor das propriedades como meio.

Trees in residential neighborhoods and communities provide benefits for homeowners that are capitalized into residential property values. In this paper, we collected data from hedonic property value studies and merged these data with ancillary spatial data describing forest and socio-economic characteristics surrounding each study area to conduct a meta-analysis of the impact of tree canopy cover on the value of residential properties. The meta-analysis suggests that property-level tree cover of about 30% and county-level tree cover of about 38% maximize the implicit price of tree cover in property values. Currently, tree cover in the original study areas was about 14%, on average, around or near study properties. The empirical results, therefore suggest under investment of tree cover on private property from the perspective of individual property owners and from a societal perspective. The findings also have implications for community forest programs regarding planting trees and protection of mature trees to address potential changes in tree abundance, species diversity and stand age due to development and climate change.

Renda mínima no TED

Um assunto que eu ainda não tinha falado antes por aqui, mas aí vai.

As usual, the TED community has lots of news to share this week. Below, some highlights. A real-world test of basic income. Too often, humanitarian aid donations of food and materials, while well-intentioned, aren’t what the recipients actually need. But what about a different approach: giving people a basic income to spend however they like.…

Sistema de Inovação do Brasil

O CGEE publicou um estudo com propostas para o sistema de inovação brasileiro. Segue o link:

O trabalho foi desenvolvido pelo Centro de Gestão e Estudos Estratégicos (CGEE), em parceria com os economistas Mariana Mazzucato e Caetano Penna, por meio da Universidade de Sussex (UK), para subsidiar a elaboração da Estratégia Nacional de Ciência, Tecnologia e Inovação (2016-2020) do Ministério da Ciência, Tecnologia e Inovação (MCTI).

Taí uma boa notícia…

Estudar economia não te faz uma pessoa pior! UFA!

So say Hummel, Pfaff, and Rost, in a recent paper: In view of the numerous accounting and corporate scandals associated with various forms of moral misconduct and the recent financial crisis, economics and business programs are often accused of actively contributing to the amoral decision making of their graduates. It is argued that theories and…
