We run experiments with a stag hunt and bargaining coordination game. Using a between-subjects design, we vary the identity of the opponent between someone of the same culture or a different culture. The idea is to see whether cultural norms or identity play a part in coordination decisions. We...

This paper studies the impact of ambiguity in the best shot and weakest link models of public good provision. The models are ?rst analysed theoretically. Then we conduct experiments to study how ambiguity affects behaviour in these games. We test whether subjects? perception of ambiguity differs...

In this paper, I examine the effect of introducing heterogeneity between players in a model of strategic experimentation. I consider a two-armed bandit problem in continuous time with one safe arm and a risky arm. There are two players and each has an access to such a bandit. A player using the...

Employing the by-production approach to modelling emission-generating technologies proposed in Murty, Russell, Levkoff [2012] and Murty [2015] and adapting the policy reform approach to taxation policy in public economics due to Feldstein [1975] and Guesnerie [1977], we propose a methodology to...

We study optimal tax policies in a life-cycle economy with risky human capital and permanent ability differences, where both ability and learning effort are private information of the agents. The optimal policies balance several goals: redistribution across agents, insurance against human...

Tests of overidentifying restrictions are widely used in practice. However, there is often confusion about the nature of their null hypothesis and about the interpretation of their outcome. In this note we argue that these tests give little information on whether the instruments are correlated...

As a selling mechanism, auctions have acquired a central position in the free market economy all over the globe. This development has deepened, broadened, and expanded the theory of auctions in new directions. This chapter is intended as a selective update of some of the developments and...

We study optimal policy in a New Keynesian model at zero bound interest rate where households use cash alongside with house equity borrowing to conduct transactions. The amount of borrowing is limited by a collateral constraint. When either the loan to value ratio declines or house prices fall...

What role does the proportion of fixed versus variable rate debt contracts play in the macroeconomy? We explore this issue by integrating borrowing-constrained households with a quantity-optimising banking sector that lends under either fixed or variable rates. Our framework is then used to...

We propose a set of necessary and sufficient conditions for the environmental Kuznets curve (EKC) phenomenon in a general model that permits non-smooth preferences and feasible sets and corner solutions for welfare maximisation. These conditions pertain to the relationship between the sets of...
