The United States spends twice as much per person on pharmaceuticals as European countries, in large part because prices are much higher in the US. This fact has led policymakers to consider legislation for price controls. This paper assesses the effects of a US international reference pricing...

In the early stages of the COVID-19 pandemic, masks and alcohol sanitizer were hoarded and resold in online markets. In Japan, restrictions were imposed on such resale. In this paper, we examine the effects of the resale regulations on the behavior of economic agents and changes in their...

We use a novel dataset on more than 35,000 eBay auctions for electronics to analyse Covid19-induced lockdown effects. The dataset covers pre- and lockdown periods and, for each auction, contains both auction settings fixed by the seller and the whole bidding record. The interplay of agents...

We develop a model where two players with asymmetric preferences engage in a contest game. The key novelty is the introduction of multi-dimensional rewards. We characterize the optimal prize allocation that maximizes aggregate effort. When heterogeneity in preferences is strong and the designer...

In the literature that estimates discrete games with incomplete information, researchers usually impose two assumptions. First, either the payoff function or the distribution of private information or both are restricted to follow some parametric functional forms. Second, players' behaviors are...

We develop a methodology for proving central limit theorems in network models with strategic interactions and homophilous agents. We consider an asymptotic framework in which the size of the network tends to infinity, which is useful for inference in the typical setting in which the sample...

Game theory and econometrics are central tools in economic analysis. In this paper, we study what happens if players in a game use econometric tools to form their opinion about the other players' behavior. In particular, we analyze the case where each player observes a number of outcomes of a...

We address the estimation of sample selection and endogenous treatment models with social interactions. To model the interaction between individuals in an internally consistent matter we employ a game theoretic approach based on the use of a discrete Bayesian game. We overcome the substantial...

This paper analyzes risk aversion in discriminatory share auctions. I generalize the k-step share auction model of Kastl (2011, 2012) and establish that marginal profits are set identified for any given coefficient of constant absolute risk aversion. I also derive necessary conditions for...

If bidders are better informed than the seller about a common component of auction heterogeneity, the seller can allocate more efficiently by keeping her reserve price secret and revising it using submitted bids. We build a model of a first-price auction under unobserved auction...
