Are uncertainty shocks a major source of business cycle fluctuations? This paper studies the effect of a mean preserving shock to the variance of aggregate total factor productivity (macro uncertainty) and to the dispersion of entrepreneurs' idiosyncratic productivity (micro uncertainty) in a financial accelerator DSGE model with sticky prices. It explores the different mechanisms through which uncertainty shocks are propagated and amplified. The time series properties of macro and micro uncertainty are estimated using U.S. aggregate and firm-level data, respectively. While surprise increases in micro uncertainty have a larger impact on output than macro uncertainty, these account for a small (non-trivial) share of output volatility.

This paper shows that when agents learn from prices, large private uncertainty may result from a small amount of heterogeneity. As in a Phelps-Lucas island model, final producers look at the prices of their local inputs to infer aggregate conditions. However, market linkages between islands make the informativeness of local prices endogenous to general equilibrium relations. In this context, I show that a vanishingly small heterogeneity in local conditions is enough to generate an equilibrium in which prices are rigid to aggregate shocks and transmit only partial information. I use this insight as a microfoundation for price rigidity in an otherwise frictionless monetary model and show that even a tiny amount of dispersion in fundamentals can lead to large non-neutrality of money.

We propose a new theory of price rigidity based on firms' Knightian uncertainty about their competitive environment. This uncertainty has two key implications. First, firms learn about the shape of their demand function from past observations of quantities sold. This learning gives rise to kinks in the expected profit function at previously observed prices, making those prices both sticky and more likely to reoccur. Second, uncertainty about the relationship between aggregate and industry-level inflation ensures nominal rigidity. We prove the main insights analytically and also quantify the effects of our mechanism. Our estimated quantitative model is consistent with a wide range of micro-level pricing facts that are typically challenging to match jointly, and implies significant monetary non-neutrality.

"In this paper, we survey the theoretical and empirical literature to investigate why nominal wages can be downwardly rigid. Looking back from the 19th century until recently, we first examine the existence and extent of downward nominal wage rigidity (DNWR) for several countries. We find that (1) nominal wages were flexible in the 19th century and first half of the 20th century, but (2) nominal wages were downwardly rigid in almost all industrialized countries in the second half of the 20th century, although (3) the extent of DNWR varied from country to country. Next, we use a behavioral economics framework to explain the reasons for DNWR. We also explain why the existence and extent of DNWR varied between time periods and/or from country to country, focusing on differences in the labor market characteristics (such as labor mobility and employment protection legislation) and in the macroeconomic environment (such as economic growth and inflation), which can alter employees' and firms' perceptions toward nominal wage cuts."--Authors' abstract.

Yes, it makes a lot of sense. This paper studies how to design simple loss functions for central banks, as parsimonious approximations to social welfare. We show, both analytically and quantitatively, that simple loss functions should feature a high weight on measures of economic activity, sometimes even larger than the weight on inflation. Two main factors drive our result. First, stabilizing economic activity also stabilizes other welfare relevant variables. Second, the estimated model features mitigated inflation distortions due to a low elasticity of substitution between monopolistic goods and a low interest rate sensitivity of demand. The result holds up in the presence of measurement errors, with large shocks that generate a trade-off between stabilizing inflation and resource utilization, and also when ensuring a low probability of hitting the zero lower bound on interest rates.

A timeless classic of economic theory that remains fascinating and pertinent today, this is Frank Knight's famous explanation of why perfect competition cannot eliminate profits, the important differences between "risk" and "uncertainty," and the vital role of the entrepreneur in profitmaking. Based on Knight's PhD dissertation, this 1921 work, balancing theory with fact to come to stunning insights, is a distinct pleasure to read. FRANK H. KNIGHT (1885-1972) is considered by some the greatest American scholar of economics of the 20th century. An economics professor at the University of Chicago from 1927 until 1955, he was one of the founders of the Chicago school of economics, which influenced Milton Friedman and George Stigler.

In The Structural Foundations of Monetary Policy, Michael D. Bordo, John H. Cochrane, and Amit Seru bring together discussions and presentations from the Hoover Institution's annual monetary policy conference. The conference participants discuss long-run monetary issues facing the world economy, with an emphasis on deep, unresolved structural questions. They explore vital issues affecting the Federal Reserve, the United States' central bank. They voice concern over the Fed's independence, governance, and ability to withstand future shocks and analyze the effects of its monetary policies and growing balance sheet in the wake of the 2008 financial crisis. The authors ask a range of questions that get to the heart of twenty-first-century monetary policy. What should the role of the Fed be? Which policies and strategies will mitigate the risks of the next crisis and at the same time spur innovation and job creation? How can new technology make the Fed's payment system safer, faster, and more efficient? What does the emergence of crypto-currencies such as Bitcoin mean for competition and stability? How can the Fed defend itself against exploitation and politicization? Finally they propose reforms to ensure that the Fed will remain independent, stable, strong, and resilient in an unpredictable world.
