In this paper we replicate most of the stylized facts characterizing the decline in business dynamism in the USA highlighted by Akcigit and Ates (2021) and provide an explanation of their emergence by means of a macroeconomic agent-based model populated by two types of firms: innovators who...

We use an analytically tractable heterogeneous‐agent (HANK) version of the standard New Keynesian model to show how the size of fiscal multipliers depends on (i) the distribution of factor incomes, and (ii) the source of nominal rigidities. With sticky prices but flexible wages, the standard...

This study develops simulation scenarios to understand the impact of green innovation policies on carbon emissions and output in an oligopolistic manufacturing industry. We introduce an agent-based model of endogenous innovation in technologies with heterogeneous production costs and carbon...

This short chapter reviews the application of patent incentives to inventions made by AI machines. It discusses two policy goals of patents in this space, namely acceleration of innovation with the help of AI but also the need to continue human progress. It reviews decisions by several courts,...

Problem definition: We study the procurement decisions of a trade agent: The agent chooses a bid (unit price to pay) to procure the goods available from seller(s). If the agent wins the bid, the supply is used to meet the buyer’s demand. Methodology/results: The trade agent’s single-period,...

How robust are socioeconomic agent-based models with respect to the details of the agents' decision rule? We tackle this question by considering an occupation model in the spirit of the Sakoda-Schelling model, historically introduced to shed light on segregation dynamics among human groups. For...

We reconsider de Marti and Zenou (2017) model of friendship network formation where individuals belong to two different communities and costs of forming links depend on community memberships. Many inefficient friendship networks such as segregation can arise when all individuals are myopic. Once...

In this work, we ask whether tradable emissions permits, based on the cap-and-trade principle,provide better climate change and economic projections than alternative regulations for GHG emissions, such as operational permits which are commonly used to mitigate non-GHG emissions (prevention first...
