Interest rates in major advanced economies have drifted down and in greater unison over the past few decades. A country's rate of interest can be thought of as reflecting movements in the global neutral rate of interest, the domestic neutral rate, and the stance of monetary policy. Only the...

This paper treats programs in which firms voluntarily agree to meet environmental standards as "green clubs": clubs, because they provide non-rival but excludable reputation benefits to participating firms; green, because they also generate environmental public goods. The model illuminates a...

Novel empirical insights by their very nature tend to be unanticipated, and in some cases at odds with the current state of knowledge on the topic. The mechanics of statistical inference suggest that such initial findings, even when robust and statistically significant within the study, should...

A central authority possessing tax and expenditure responsibilities can readily provide an efficient level of a public good. Absent a central authority, voluntary arrangements must replace coercive ones. Significant under-provision must be expected. International public goods are particularly...

We present a dynamic model of free riding in which n infinitely lived agents choose between private consumption and contributions to a durable public good g. We characterize the set of continuous Markov equilibria in economies with reversibility, where investments can be positive or negative; and...

We present and experimentally test a mechanism that provides a simple, natural, low cost, and realistic solution to the problem of compliance with socially determined efficient actions, such as contributing to a public good. We note that small self-governing organizations often place enforcement...

This chapter reviews academic research on the connections between agglomeration and innovation. We first describe the conceptual distinctions between invention and innovation. We then describe how these factors are frequently measured in the data and some resulting empirical regularities....

This paper provides evidence for why individuals join unions instead of free-riding. I model membership as legal insurance. To test the model, I use the incidence of news stories concerning allegations against teachers in the UK as a plausibly exogenous shock to demand for such insurance. I find...

Maintaining sufficient liquidity in the financial system is vital for its stability. However, since returns on liquid assets are typically low, individual financial institutions may seek to hold fewer such assets, especially if they believe they can rely on other institutions for liquidity...

We analyze government interventions to alleviate debt overhang among banks. Interventions generate two types of rents. Informational rents arise from opportunistic participation based on private information while macroeconomic rents arise from free riding. Minimizing informational rents is a...
