Energy's impact on inflation expectations
Some closely watched measures of inflation expectations have been in gradual decline over the past five years. Over the same time, oil prices have fallen dramatically. Although the movements in energy prices are normally considered temporary, they appear to have played a large role in pushing down some longer-term forecasts for consumer price index inflation from professional forecasters. Analysis shows the drop in energy prices can explain about three-fourths of the decline in these professional inflation forecasts over the past five years.

The Evolution of the FOMC’s Explicit Inflation Target
Analyzing the narrative of historical Federal Open Market Committee meeting transcripts provides insights about how inflation target preferences of participants have evolved over time. From around 2000 until the Great Recession, there was general consensus among participants that their inflation target should be about 1%, significantly below both average inflation over the period and survey measures of longer-run inflation expectations. By the end of the recession in 2009, however, the consensus had shifted up to 2%, which became the official target announced to the public in January 2012.

The effects of competition on price dispersion in the airline industry: a panel analysis
This paper analyzes the effects of market structure on price dispersion in the airline industry, using panel data from 1993 through 2006. The results found in this paper contrast with those of Borenstein and Rose (1994), who found that price dispersion increases with competition. We find that competition has a negative effect on price dispersion, in line with the textbook treatment of price discrimination. Specifically, the effects of competition on price dispersion are most significant on routes that we identify as having consumers characterized by relatively heterogeneous elasticities of ...

Measuring News Sentiment
This paper demonstrates state-of-the-art text sentiment analysis tools while developing a new time-series measure of economic sentiment derived from economic and financial newspaper articles from January 1980 to April 2015. We compare the predictive accuracy of a large set of sentiment analysis models using a sample of articles that have been rated by humans on a positivity/negativity scale. The results highlight the gains from combining existing lexicons and from accounting for negation. We also generate our own sentiment-scoring model, which includes a new lexicon built specifically to ...

What's Down with Inflation?
After eight years of economic recovery, inflation remains below the FOMC?s target. Dissecting the underlying price data by spending category reveals that low inflation largely reflects prices that are relatively insensitive to overall economic conditions. Notably, modest increases in health-care prices, which have been held down by mandated cuts to the growth of Medicare payments, have helped moderate overall inflation. Further slow growth in health-care prices is likely to remain a drag on inflation.

The Costs of Payment Uncertainty in Healthcare Markets
What does it cost healthcare providers to collect payment in the complex U.S. health insurance system? We study this question using rich data on repeated interactions between a large sample of physicians and many different payers, and investigate the consequences when these costs are high. Payment uncertainty is high and variable, with 19% of Medicaid visits not reimbursed after the first claim submission. In such cases, physicians either forgo substantial revenue or incur costs to collect payment. Using physician movers and practices that span state boundaries, we find that providers respond ...

Pandemic-Era Liquid Wealth Is Running Dry
Households accumulated more liquid assets beginning in 2020 than would have been expected without the pandemic. These “extra” liquid assets have dissipated, but their evolution has differed significantly by income group. While middle- and lower-income households hold substantially less liquid wealth than implied by pre-pandemic projections, the level for higher-income households remains close to its pre-pandemic path. Over the same period, credit card delinquency rates initially dropped and, more recently, have steadily risen as pandemic-era liquid wealth was depleted, especially for ...

Price Setting in an Innovative Market
We examine how the confluence of competition and upstream innovation influences downstream firms? profit-maximizing strategies. In particular, we analyze how, in light of these forces, the downstream firm sets the price of the product over its life cycle. We focus on personal computers (PCs) and introduce two novel data sets that describe prices and sales in the industry. Our main result is that a vintage-capital model that combines a competitive market structure with a rapid rate of innovation is well able to explain the observed paths of prices, as well as sales and consumer income, over a ...

Decomposing Medical-Care Expenditure Growth
Medical-care expenditures have been rising rapidly, accounting for almost one-fifth of GDP in 2009. In this study, we assess the sources of the rising medical-care expenditures in the commercial sector. We employ a novel framework for decomposing expenditure growth into four components at the disease level: service price growth, service utilization growth, treated disease prevalence growth, and demographic shift. The decomposition shows that growth in prices and treated prevalence are the primary drivers of medical-care expenditure growth over the 2003 to 2007 period. There was no growth in ...

Subprime outcomes: risky mortgages, homeownership experiences, and foreclosures
This paper provides the first rigorous assessment of the homeownership experiences of subprime borrowers. We consider homeowners who used subprime mortgages to buy their homes, and estimate how often these borrowers end up in foreclosure. In order to evaluate these issues, we analyze homeownership experiences in Massachusetts over the 1989?2007 period using a competing risks, proportional hazard framework. We present two main findings. First, homeownerships that begin with a subprime purchase mortgage end up in foreclosure almost 20 percent of the time, or more than 6 times as often as ...
