By allowing for imperfectly informed markets and the role of private information, we offer new insights about observed deviations of portfolio concentrations in domestic relative to foreign risky assets, or "home bias", from what standard finance models predict. Our model ascribes the "bias" to...

We ran a field experiment to investigate whether nudge policies, consisting in behavioural insight messaging, help to improve performance in financial trading. Our experiment involved students enrolled in a financial trading course in an Italian University who were invited to trade on Borsa...

Two of the top economics journals have institutional ties to a specific university, the Quarterly Journal of Economics (QJE) to Harvard University and the Journal of Political Economy (JPE) to the University of Chicago. Researchers from Harvard, but also nearby Massachusetts Institute of...

We present a simple framework for analyzing decline in union voice in the Anglo-American world and its replacement by non-union, often direct, forms of worker voice. We argue that it is a decline in the in-flow to unionisation among employers and workers, rather than an increase in the outflow...

We estimate how trade openness affects the relationship between wages, labour productivity and foreign wages using sector-level time series for several EU member states. In some countries wages became less responsive to foreign wages as trade costs declined. We show this counter-intuitive result...

The Coase theorem emphasizes the role transactions costs play in efficient market outcomes. We document inefficient outcomes, in the presence of a transactions cost, in southern California land markets and the corresponding transition to efficient outcomes after the transactions cost is...

We characterize how public insurance schemes are constrained by hidden financial transactions. When non-exclusive private insurance entails increasing unit transaction costs, public transfers are only partly offset by hidden private transactions, and can influence consumption allocation. We show...

In this paper we adapt the model of MacLeod (2007) to provide one way to formally implement some of Williamson's ideas regarding the effect of transactions costs upon employment relationship. We then explore the empirical implications of this model with a data set that measures job...

Do leader networks promote efficient intergovernmental contracts? We examine a groundbreaking policy in China where subprovincial governments freely traded land conversion quotas, and investigate the role of leader networks on the boundary between jurisdictions that embrace trade versus autarky....
