How do the different elements in the standard bundle of property rights - such as the right of possession or the right of transfer - differentially impact outcomes, such as urban development?

How do the different elements in the standard bundle of property rights, including those of possession and transfer, influence the shape of cities? This paper incorporates insecure property rights into a standard model of urban land prices and density, and makes predictions about investment in...

We examine a new data set of laws and practices governing public procurement, as well as procurement outcomes, in 187 countries. We measure regulation as restrictions on discretion of the procuring agents. We find that laws and practices are highly correlated with each other across countries,...

We examine the patterns of media ownership in 97 countries around the world. We find that almost universally the largest media firms are owned by the government or by private families. Government ownership is more pervasive in broadcasting than in the printed media. Government ownership of the...

We introduce diagnostic expectations into a standard setting of price formation in which investors learn about the fundamental value of an asset and trade it. We study the interaction of diagnostic expectations with two well-known mechanisms: learning from prices and speculation (buying for...

In line with Keynes' intuition, volatility in the stock market and in real economic activity are linked by expectations of long term profits. We show that analysts' optimism about the long term earnings growth of S&P 500 firms is associated with a near term boom in major US financial markets,...

We document two new facts about the distributions of answers in famous statistical problems: they are i) multi-modal and ii) unstable with respect to irrelevant changes in the problem. We offer a model in which, when solving a problem, people represent each hypothesis by attending "bottom up" to...

How do people form beliefs about novel risks, with which they have little or no experience? A 2020 US survey of beliefs about the lethality of Covid reveals that the elderly underestimate, and the young overestimate, their own risks, and that people with more health adversities are more...

We present the case for the centrality of overreaction in expectations for addressing important challenges in finance and macroeconomics. First, non-rational expectations by market participants can be measured and modeled in ways that address some of the key challenges posed by the rational...

Tunnelling is defined as the transfer of assets and profits out of firms for the benefit of their controlling shareholders. We describe the various forms that tunnelling can take, and examine under what circumstances it is legal. We discuss two important legal principles -- the duty of care and...
