Purpose of experiments in economics -Testing theory (predictions, competing ideas, assumptions) -Searching for facts (generating knowledge about complex situations) -Whispering in the ears of princes (testing behavioural consequences of policies, how to influence agents)
Experimental economics is the application of experimental methods [1] to study economic questions. Data collected in experiments are used to estimate effect size , test the validity of economic theories, and illuminate market mechanisms.
- What are experiments?
- • Does a particular treatment or intervention cause a change in outcomes or behavior?
- 2. Controlled Experiments versus Natural Experiments
- Controlled or Randomized Experiments
- Natural Experiments or Quasi-Experiments
- Randomized and Natural Experiments: Similarities
- Randomized and Natural Experiments: Differences
- 3. Elements of a Natural Experiment
- 5. A Simple Difference-in-Differences Estimator of the Treatment Effect
- − [ E ( Y A = 1 ,T = 0 ) − E ( Y A = 0 , T = 0 ) ]
- = treatment group-control group difference in conditional mean Y in the post-intervention period
- Regression Model for Computing an Adjusted Difference-in-Differences Estimate of the Treatment Effect
Experiments are empirical methodologies for estimating the causal effect of specific treatments, interventions or events on observed outcomes or behaviors. What is the objective of experiments? The fundamental objective of experiments is to estimate accurately and precisely the causal effect of a treatment, intervention or event on observed out...
Examples: Does participation in a job training program cause an increase in the employment earnings of program participants? Does an increase in the minimum wage cause a decrease in the employment of low-skilled, low-wage workers? Does more generous workers’ compensation cause an increase in the length of time that injured workers remain out...
There are two broad types of experimental research designs: Controlled or Randomized Experiments Common in medical research and in the physical and natural sciences Much less common in economics Natural Experiments or Quasi-Experiments More common in economics
controlled experiment, or randomized experiment, is one in which the assignment of subjects to treatment and control groups is done randomly, such as by tossing a coin. The distinguishing characteristic of a controlled or randomized experiment is the random assignment of subjects to treatment and control groups. The major advantage of random assi...
A natural experiment, or quasi-experiment, is one in which some exogenous event – such as a change in government policy or program – changes the environment in which economic agents (individuals, families, or firms) operate so as to partition the population of agents into two groups: a treatment group which is possibly affected by the event, and a ...
A common characteristic of both randomized experiments and natural experiments is the creation of two groups of entities, agents or subjects: a treatment group comprised of subjects that receive the treatment or experience the event in question; a control group comprised of subjects that do not receive the treatment or experience the event in q...
The critical difference between randomized experiments and natural experiments is the mechanism by which entities or agents are partitioned into a treatment group and a control group. In randomized experiments, subjects are assigned to treatment and control groups by some sort of randomizing procedure. In natural experiments, entities are partiti...
Objective: To estimate the causal effect of some “treatment” – i.e., of some exogenous event or policy intervention – on an outcome variable Y. Examples of treatments – of program or policy interventions The participation of some workers in a job training program The adoption of (or a mandated increase of) a minimum wage in one jurisdiction An in...
The sample data are partitioned into four mutually exclusive groups (or subsets) of observations: Treatment group observations before the event or policy intervention; Treatment group observations after the event or policy intervention; Control group observations before the event or policy intervention; Control group observations after the ev...
it t i it t i = change in conditional mean Y of treatment group between pre-intervention and post-intervention periods minus change in conditional mean Y of control group between pre-intervention and post-intervention periods
minus treatment group-control group difference in conditional mean Y in the pre-intervention period
To control for the effects on the outcome variable Y of individual observed characteristics of treatment and control group members, a vector of observed control variables is included as additional explanatory variables in the linear regression model for the outcome variable Yit:
Experimental economics is an exciting new development (Samuelson and Nordhaus, 1992, p.5). Between these two editions, economists had managed to set up experiments similar to the ones conducted in the natural sciences. But, even more importantly, the results generated by these experiments began to be considered by an increasing number

Apr 10, 2019 · A natural experiment is an empirical or observational study in which the control and experimental variables of interest are not artificially manipulated by researchers but instead are allowed to be influenced by nature or factors outside of the researchers' control.
