Over the last two decades, there has been a surge of opioid-related overdose deaths resulting in a myriad of state policy responses. Researchers have evaluated the effectiveness of such policies using a wide-range of statistical models, each of which requires multiple design choices that can...

We perform a comparative analysis of machine learning methods for the canonical problem of empirical asset pricing: measuring asset risk premia. We demonstrate large economic gains to investors using machine learning forecasts, in some cases doubling the performance of leading regression-based...

We show that online prices can be used to construct quarterly purchasing power parities (PPPs) with a closely-matched set of goods and identical methodologies in a variety of developed and developing countries. Our results are close to those reported by the International Comparisons Program...

We summarize existing empirical findings regarding the adoption of robotics and AI and its effects on aggregated labor and productivity, and argue for more systematic collection of the use of these technologies at the firm level. Existing empirical work primarily uses statistics aggregated by...

In many health domains, we are concerned that observed links - for example, between “healthy” behaviors and good outcomes - are driven by selection into behavior. This paper considers the additional factor that these selection patterns may vary over time. When a particular health behavior...

This chapter will cover recent research in historical economics that uses ethnographic data and data from surveys and lab experiments. The study of historical economics, particularly outside of non-Western countries, has been constrained by availability of historical data. However, recent work...

We examine how executives' behavior outside the workplace, as measured by their ownership of luxury goods (low "frugality") and prior legal infractions, is related to financial reporting risk. We predict and find that CEOs and CFOs with a legal record are more likely to perpetrate fraud. In...

Foreign-owned firms from advanced countries carry the culture of transparency in business transactions that is orthogonal to the culture of hiding and insider dealing in many developing economies and economies in transition. In this paper, we document this using administrative data on reported...

Does corporate culture matter? Can differences in corporate culture explain why similar firms diverge with one succeeding and the other failing? To answer these questions, we use a novel survey and interview-based analysis of 1,348 North American firms. Over half of senior executives believe...
