Can Society Function Without Ethical Agents? An Informational Perspective
In order to function, society relies on many facts that must be learned through intermediaries with special expertise or access to information. This paper considers whether society can learn about such facts when intermediaries are devoid of ethical motives and act sequentially. The answer depends on the severity of information attrition affecting the amount of discoverable evidence about each fact. Information attrition is nonexistent in fields based on reproducible scientific evidence but can affect the evidence in criminal and corruption investigations. Applications to institution enforcement, social cohesion, scientific progress, and historical revisionism are discussed.

Title: “Streets of gold: The role of geography in immigrant assimilation in the US”
Abstract: The United States has absorbed two major waves of immigration: one in the late nineteenth and early twentieth century, and one today. I will present new data documenting a common pattern of immigrant assimilation in both periods, whereby the children of immigrants completely converge with and even surpass the earnings of the children of the US-born. Location choice plays an important role: immigrants move to urban areas that offer opportunities for advancement for themselves and their children. Settling in an immigrant enclave can delay assimilation, but this effect is overwhelmed by the strong tendency of immigrants to move to highly mobile locations.
17:30 – 17:40 Interdisciplinary dialogue with the audience

Title: “The Growing Link Between Space and Inequality in the US”
Abstract: I argue that space is becoming an increasingly important dimension of inequality in the US. I will describe several trends and findings that have exacerbated spatial inequality, and present new evidence showing how the division of urban space affects the economic outcomes of children. The talk concludes with three approaches to addressing spatial inequality.

Title: “Deep roots and changing fortunes: the changing geography of intergenerational social mobility in the United States over the twentieth century”
Abstract: Intergenerational social mobility (ISM) – the rate at which children born into poverty climb the income ladder – varies considerably across neighborhoods and cities in the United States. Some formerly high opportunity regions are no longer so, while other regions display consistently low levels of opportunity across the century. The changing geography of employment restructures the landscape of social mobility, but factors associated with intraregional inequality and “deep roots” generate persistence. These two forces are most sharply evident in the sharp decline in ISM for persons who grew up in the Midwest in the late twentieth century, as high-income economic activity has shifted away from it, and the persistence of the South as a low-opportunity region even as new economic activity shifted toward it.

Short and Simple Confidence Intervals when the Directions of Some Effects are Known
écrit avec Co-author: Philipp Ketz
We introduce adaptive confidence intervals on a parameter of interest in the presence of nuisance parameters, such as coefficients on control variables, with known signs. Our confidence intervals are trivial to compute and can provide significant length reductions relative to standard ones when the nuisance parameters are small. At the same time, they entail minimal length increases at any parameter values. We apply our confidence intervals to the linear regression model, prove their uniform validity and illustrate their length properties in an empirical application to a factorial design field experiment and a Monte Carlo study calibrated to the empirical application.
