Robustness, information-processing constraints, and the current account in small open economies
We examine the effects of two types of informational frictions, robustness (RB) and nite information-processing capacity (called rational inattention or RI) on the current account, in an otherwise standard intertemporal current account (ICA) model. We show that the interaction of RB and RI has the potential to improve the model?s predictions on the joint dynamics of the current account and income: (i) the contemporaneous correlation between the current account and income, (ii) the volatility and persistence of the current account in small open emerging and developed economies. In addition, we ...

Implications of recent U.S. energy trends for trade forecasts
The development of hydraulic fracturing and horizontal drilling has brought significant structural change to the energy sector, increasing energy production and decreasing net energy imports. Future changes in energy policy or technology could have even larger effects on energy exports and thus overall exports. As a result, distinguishing energy from non-energy components of trade becomes important for forecasts in both the near and longer term. Craig S. Hakkio and Jun Nie introduce models separating energy from the non-energy components of trade to examine how changes in energy production ...

Who Benefited Most from the CARES Act Unemployment Insurance Provisions?
The regular unemployment insurance (UI) program in the United States requires workers to have a minimum amount of earnings as well as a sufficient work history before unemployment. Low-wage workers are more likely to have a short work history before unemployment because they are more likely to be separated from their jobs. Pandemic Unemployment Assistance (PUA) under the CARES Act temporarily eliminated the requirements for minimum past earnings and length of employment, thus making many low-wage workers who were ineligible for UI under the regular program temporarily eligible. The extra ...

Disruptions to Russian Energy Supply Likely to Weigh on European Output
The Russia-Ukraine war and subsequent oil sanctions from European countries have substantially disrupted the supply of Russian oil and gas. We estimate the effects of these disruptions on European output and find that a decline in the Russian oil and gas supply in 2022 could lead to a sizable drop in European output over 2023–24, though the effect differs across countries and sectors .

Human Capital Dynamics and the U.S. Labor Market
The high U.S. unemployment rate after the Great Recession is usually considered to be a result of changes in factors influencing either the demand side or the supply side of the labor market. However, no matter what factors have caused the changes in the unemployment rate, these factors should have influenced workers' and firms' decisions. Therefore, it is important to take into account workers' endogenous responses to changes in various factors when seeking to understand how these factors affect the unemployment rate. To address this issue, we estimate a Mortensen-Pissarides style of ...

Production and Inventory Dynamics under Ambiguity Aversion
We propose a production-cost smoothing model with Knightian uncertainty due to ambiguity aversion to study the joint behavior of production, inventories, and sales. Our model can explain four facts that previous studies find difficult to account for simultaneously: (i) the high volatility of production relative to sales, (ii) the low ratio of inventory-investment volatility to sales volatility, (iii) the positive correlation between sales and inventories, and (iv) the negative correlation between the inventory-to-sales ratio and sales. We find that the stock-out avoidance motive (Kahn 1987) ...

Training or search? evidence and an equilibrium model
Training programs are a major tool of labor market policies in OECD countries. I use a unique panel data set on the labor market experience of individual German workers between 2000 and 2002 to estimate a dynamic model of search and training, which allows me to quantify the impact of training programs and unemployment benefits on employment, unemployment, output, and the government expenditures. ; The model extends Ljungqvist and Sargent (JPE, 1998) by incorporating a training decision and a broader menu of unemployment benefits. Government-sponsored training programs feature a key trade-off ...

Economic growth in foreign regions and U.S. export growth
U.S. export growth depends crucially on foreign demand. Lower foreign economic growth is associated with lower U.S. export growth. And recently, some parts of the world, particularly Asia and Europe, have shown signs of slowing growth. ; Disaggregating historical data by region, authors Nie and Taylor measure the changes in U.S. export growth associated with changes in different regions' economic growth. They find the change in U.S. export growth associated with change in a given foreign region's growth depends both on the size of the region's economy and on the share of U.S. exports destined ...

Model uncertainty, state uncertainty, and state-space models
This technical paper considers ways to capture uncertainty in the context of so-called "state-space" models. ; State-space models are powerful tools commonly used in macroeconomics, international economics, and finance. State-space models can generate estimates of an underlying, ultimately unobserved variable?such as the natural rate of unemployment?based on the movements of other variables that are observed and have some relationship to the unobserved variable. The paper shows how several macroeconomic models can be mapped to the state-space framework, thus helping quantify uncertainty ...
