Pricing decisions in an experimental dynamic stochastic general equilibrium economy
We construct experimental economies, populated with human subjects, with a structure based on a nonlinear version of the New Keynesian Dynamic Stochastic General Equilibrium (DSGE) model. We analyze the behavior of firms' pricing decisions in four different experimental economies. We consider how well the experimental data conform to a number of accepted empirical stylized facts. Pricing patterns mostly conform to these patterns. Most price changes are positive, and inflation is strongly correlated with average magnitude, but not the frequency, of price changes. Prices are affected negatively ...

Risk Preferences at the Time of COVID-19: An Experiment with Professional Traders and Students
We study whether the COVID-19 pandemic has impacted risk preferences, comparing the results of experiments conducted before and during the outbreak. In each experiment, we elicit risk preferences from two sample groups: professional traders and undergraduate students. We find that, on average, risk preferences have remained constant for both pools of participants. Our results suggest that the increases in risk premia observed during the pandemic are not due to changes in risk appetite; rather, they are solely due to a change in beliefs by market participants. The findings of our paper support ...

Bargaining Under Liquidity Constraints: Nash vs. Kalai in the Laboratory
We report on an experiment in which buyers and sellers engage in semi-structured bargaining in two dimensions: how much of a good the seller will produce and how much money the buyer will offer the seller in exchange. Our aim is to evaluate the empirical relevance of two axiomatic bargaining solutions, the generalized Nash bargaining solution and Kalai's proportional bargaining solution. These bargaining solutions predict different outcomes when buyers are constrained in their money holdings. We first use the case when the buyer is not liquidity constrained to estimate the bargaining power ...

Is Money Essential? An Experimental Approach

Endogenous Leverage and Default in the Laboratory
We study default and endogenous leverage in the laboratory. To this purpose, we develop a general equilibrium model of collateralized borrowing amenable to laboratory implementation and gather experimental data. In the model, leverage is endogenous: agents choose how much to borrow using a risky asset as collateral, and there are no ad hoc collateral constraints. When the risky asset is financial?namely, its payoff does not depend on ownership (such as a bond)? collateral requirements are high and there is no default. In contrast, when the risky asset is nonfinancial?namely, its payoff ...

Inflation Expectations and Behavior: Do Survey Respondents Act on Their Beliefs?
Surveys of consumers’ inflation expectations are now a key component of monetary policy. To date, however, little work has been done on 1) whether individual consumers act on their beliefs about future inflation, and 2) whether the inflation expectations elicited by these surveys are actually informative about the respondents’ beliefs. In this post, we report on a new study by Armantier, Bruine de Bruin, Topa, van der Klaauw, and Zafar (2010) that investigates these two issues by comparing consumers’ survey-based inflation expectations with their behavior in a financially incentivized ...
