[Economics SIG] David Wheat on “Modeling Aggregate Firm Demographics and Employment”

Please join us online Friday, April 8th Noon ET (Boston time. Here is a time converter).

In this Collective Learning Meeting (CLM), the System Dynamics Society’s Economics SIG and WPI System Dynamics host I. David Wheat (dwheat@usefulmodels.net) who will present 

Modeling Aggregate Firm Demographics and Employment

Short Description: Motivated by Khalid Saeed’s modeling of Schumpeter’s ‘creative destruction’ hypothesis, my model uses an aging chain and co-flow approach to replicate the trends and patterns observed in the U.S. Census Bureau’s aggregate ‘business dynamics’ statistics—those relating to the formation and closing of firms and their establishments, the historical transition from startups to mature firms and, eventually, the end of a business life. The model also replicates the aggregate employment pattern associated with employment at age-specific business firm establishments.

Question(s)/Comments for the Audience: This is part of a comprehensive modeling effort that aims to provide a plausible endogenous explanation for the declining trend in the number of start-up firms in the U.S. economy and, more fundamentally, an explanation for the underlying decline in entrepreneurial activity. This is a wide-ranging project, and collaborators are especially welcome to help with the literature review and data analysis tasks.

Biography: Emeritus Professor Wheat studies economic systems. His research specialty is simulation modeling of macroeconomic structure and behavior in Ukraine and Lithuania, in addition to the United States. For many years, he taught the modeling process course at the University of Bergen, and he continues to teach a policy design course and a course in macrodynamics. Unable to spell retirement, he teaches 10 courses yearly in Norway, Ukraine, Lithuania, and the U.S. His projects include collaboration with Ukrainian economists to build dynamic modeling capacity at national universities in Kyiv and Lviv, creation of a system dynamics version of the central bank’s monetary policy model and, until the war, building an economic policy model for Ukrainian government ministries.   He also worked with economists at Lithuania’s central bank to develop a multi-industry system dynamics model of price dynamics in Europe. Prior to joining academia in Norway, he managed his own consulting business in the U.S. and, earlier, served as staff assistant to the President of the United States.

We will not record this presentation.

Mehdi Moghadam Manesh and Reza Eslamifar on “Groundwater Depletion in Iran: Does Rural Youth Migration Matter?”

Please join us online Friday, March 25th Noon ET (Boston time. Here is a time converter).

In this Collective Learning Meeting (CLM), WPI System Dynamics, the System Dynamics Society’s Water SIG and the Transboundary Groundwater Resiliency Research (TGRR) network host Mehdi Moghadam Manesh and Reza Eslamifar who will present

Groundwater Depletion in Iran: Does Rural Youth Migration Matter?

Short Description: Iranian agriculture relies heavily on groundwater resources and is responsible for more than 90% of groundwater consumption. The groundwater-dependent agriculture has led to the consumption of about 100 billion cubic meters of groundwater resources in less than 50 years. The main reasons for this dependence are surface water scarcity, low annual precipitation, and improper spatial and temporal distributions of the precipitation. Given such factors and Iranian leaders’ aspirations for agricultural self-sufficiency, groundwater depletion is not surprising. However, two other factors accelerate groundwater depletion: low irrigation efficiency and competition between farmers to harvest more water, referred to as “the tragedy of the commons” in the economic literature. Therefore, although geographical, climatic, and political factors are beyond our control, by encouraging farmers to cooperate and improve irrigation technology, it can be hoped that the problem of groundwater depletion will be managed to some extent. Now, Iran witnesses an increasing rural migration. In this study, we are interested in understanding:

  • How can rural youth migration affect “self-organized collective action” and farmers’ motivation to improve irrigation efficiency?
  • Under what circumstances may rural youth migration decrease/ increase groundwater consumption?

 

Biographies:

Mehdi Moghadam Manesh has a BS in mechanical engineering and an MBA and MS in system dynamics. He is passionate about applying system dynamics for policymaking, strategic management, and sustainable development. For additional information, please visit his LinkedIn profile.

Reza Eslamifar has a BS in IT engineering, an MBA, and a PhD in public policy.

 

We will record this session and post it to the System Dynamics Society’s YouTube channel.

Timothy Clancy on “Enriching our Causal Vocabulary: Expanding the Language of System Dynamics”

Please join us online Friday, February 18th Noon ET (Boston time. Here is a time converter). In this Collective Learning Meeting (CLM), WPI System Dynamics PhD Candidate Timothy Clancy (timc@dialecticsims.com) will present

Enriching our Causal Vocabulary:
Expanding the Language of System Dynamics

Short Description: In the last 20 years, there has been a heightened interest in the fields of physics, biology, cosmogony, and complex systems science on differentiating types of causation. In this presentation, Timothy introduces many of these terms to practitioners. What is the difference between top-down and bottom-up causation or between coarse-graining and fine-graining causal chains? What are causal classes, ranks, and types? For a field seeking to simulate causal relationships in structure – are we introducing these terms into our work and techniques?

Question(s) for the Audience: This is an early draft CLM presentation for a working draft paper Timothy is working on. Q&A is expected and encouraged around the topic generally and in specific the areas Timothy is asking for help on:

1. Does SD literature currently use or reference these terms?
2. Are there SD modeling techniques to represent these causal mechanisms?
3. Are these techniques incorporated in SD methods for developing hypotheses and assessing theory?
