Top-down versus bottom-up macroeconomics
De Grauwe, Paul - 2010
I distinguish two types of macroeconomic models. The first type are top-down models in which some or all agents are capable of understanding the whole picture and use this superior information to determine their optimal plans. The second type are bottom-up models in which all agents experience...

Behavioral economics and macroeconomic models
Driscoll, John C.; Holden, Steinar - 2014 - This version: 7 April 2014
Over the past 20 years, macroeconomists have incorporated more and more results from behavioral economics into their models. We argue that doing so has helped fixed deficiencies with standard approaches to modeling the economy-for example, the counterfactual absence of inertia in the standard...

Have macroeconomic models lost their connection with economic reality?
Veen, Tom van - 2020
Macroeconomic theory has developed into increasingly sophisticated mathematical models. In the words of Mankiw … the development of macroeconomic theory over the past 40 years. The focus is on the main lines of thinking and the story … changes in macroeconomic theory and that the current debates after the GFC will be the start of a more plural approach to …

The macroeconomics of TANSTAAFL
Grossmann, Volker; Steger, Thomas M.; Trimborn, Timo - 2011
This paper shows that dynamic inefficiency can occur in dynamic general equilibrium models with fully optimizing, infinitely-lived households even in a situation with underinvestment. We identify necessary conditions for such a possibility and illustrate it in a standard R&D-based growth model....

International trade and monopolistic competition without CES : estimating translog gravity
Novy, Dennis - 2010
This paper derives a micro-founded gravity equation in general equilibrium based on a translog demand system that allows for endogenous markups and rich substitution patterns across goods. In contrast to standard CES-based gravity equations, trade is more sensitive to trade costs if the...

Theory and practice of GVAR modeling
Chudik, Alexander; Pesaran, M. Hashem - 2014
The Global Vector Autoregressive (GVAR) approach has proven to be a very useful approach to analyze interactions in the global macroeconomy and other data networks where both the cross-section and the time dimensions are large. This paper surveys the latest developments in the GVAR modeling,...

A microfoundation of predator-prey dynamics
Eichner, Thomas; Pethig, Rüdiger - 2003
Predator-prey relationships account for an important part of all interactions between species. In this paper we provide a microfoundation for such predator-prey relations in a food chain. Basic entities of our analysis are representative organisms of species modelled similar to economic...

A micro-level 'consumer approach' to species population dynamics
Christiaans, Thomas (contributor);  … - 2005
In this paper we develop a micro ecosystem model whose basic entities are representative organisms which behave as if maximizing their net offspring under constraints. Net offspring is increasing in prey biomass intake, declining in the loss of own biomass to predators and Allee's Law applies....

The weak rationality principle in economics
Kirchgässner, Gebhard (contributor) - 2005
The weak rationality principle is not an empirical statement but a heuristic rule of how to proceed in social sciences. It is a necessary ingredient of any ‘understanding’ social science in the Weberian sense. In this paper, first this principle and its role in economic theorizing is...
