## Interpreting models

While interpreting results of a model we have to accomplish three things: We have to phrase results that are usually contained in mathematical expressions in words that can be understood …

## Solving Models: First-best and Second-best Solutions

When analyzing environmental policy measures, we often have to face more than a single problem. For instance, we might have to regulate emissions but do not know for certain, how …

## How to build a theoretical model: Basic building blocks

Solving the model is a crucial step, as it shows whether a model that we have developed is indeed useful, or whether it needs to be changed. Can the model …

## Wrap up

This week we have learned different mathematical model types, their impact on the obtainable solutions and the limitations imposed by data availability. Compared to the Problem and Model steps of …

## Data output

When you finally got your model results there are two things to do: first, you need to make sure the numbers are correct; and second, you need to transfer the …

## Data input

Getting the data needed to run a numerical model is oftentimes the most frustrating part of the whole modeling process, simply for the fact that data is hard to get …

## Get to know your model

Modern computer capacities and advances in modeling software and algorithms make numerical modeling much more accessible than a few decades ago. Nevertheless, basic understandings of the mathematical model structure and …

## How to get numbers out of a model?

In this week we want to learn how to actually solve our numerical models, and produce the numbers we want to interpret. In week 3 you learned how to design …

## Live Event: Discussing your first modeling ideas

In this live step the educators discussed the assignments uploaded by the Case Study Groups in a round table discussion. During the live event, which took place on Google Hangouts, …

## First modeling ideas of Case Study Groups

Modeling is an extremely complex process. While we enjoy your submissions and try to answer all your questions, we can do so in this framework only to a certain degree. …

## How to build a numerical model III: Which model type to choose?

In Step 3.6 you have learned that the choice of optimization or equilibrium formulation is often more a choice of preferences in model design and the underlying economic thinking than …

## How to build a numerical model III: Which model type to choose?

Often the optimization and equilibrium approach can be transferred into each other and are thereby equally fitted for your model. Naturally, there are plenty of computational reasons to choose one …

## How to build a numerical model II: Balancing the world

Contrary to an optimization problem, an equilibrium model has no objective but consists of the respective conditions that need to hold when the market or system is in equilibrium, meaning …
