The US spends more than 4 trillion dollars per year on health care, largely conducted by private providers and reimbursed by insurers. A major concern in this system is overbilling, waste and fraud by providers, who face incentives to misreport on their claims in order to receive higher...

Using only 34 published tables, we reconstruct five variables (census block, sex, age, race, and ethnicity) in the confidential 2010 Census person records. Using the 38-bin age variable tabulated at the census block level, at most 20.1% of reconstructed records can differ from their confidential...

We study the role of global financial intermediaries in international lending. We construct a model of the world economy, in which heterogeneous borrowers issue risky securities purchased by financial intermediaries. Aggregate shocks transmit internationally through financial intermediaries' net...

We use micro data from Orbis on firm level balance sheets and income statements to document that accounting returns for privately held businesses are dispersed, persistent, and negatively correlated with firm equity. We also show that firms experience large, fat-tailed, and partly transitory...

A new class of Capital Asset Pricing Models (CAPM) arises from the first principle of real investment for individual firms. Conceptually as "causal"' as the consumption CAPM, yet empirically more tractable, the investment CAPM emerges as a leading asset pricing paradigm. Firms do a good job in...

This paper assesses the current state of knowledge about crisis risk and its implications for risk management. Better data that became available since the Global Financial Crisis (GFC) has improved our understanding of crisis risk. These data have been used to show that some types of crises...

Existing evidence shows convincingly that expected cash flows of non-financial firms can be negatively affected by their total risk, so that non-financial firms can create shareholder wealth by managing their total risk. After reviewing theories that demonstrate links between firm value and...

China's admission into the WTO in 2001 heralded a new era of globalization, increasing both import competition in domestic markets and foreign opportunities for US firms. In the aggregate, the average annual profitability of US public firms during the post globalization period (2003-2019)...

In the face of rising climate risk, financial institutions may adapt by transferring such risk to securitizers that have the skill and expertise to build diversified pools, such as Mortgage-Backed Securities. In diversified pools, exposure to climate risk may be a drop in the ocean of cash...

This paper proposes latent factor models for multidimensional panels called 3D-PCA. Factor weights are constructed from a small set of dimension-specific building blocks, which give rise to proportionality restrictions of factor weights. While the set of feasible factors is restricted, factors...
