Implications of structural changes in the U.S. economy for pricing behavior and inflation dynamics
Some key features of the behavior of inflation in the United States appear to have changed in the past 20 years, with potentially important implications for forecasters and policymakers. Recent studies have provided evidence of a decline in both the variability and persistence of inflation. ; Such shifts in the behavior or dynamics of inflation would necessitate changes in the economic relationships used by policymakers and economists to assess current conditions, forecast key economic indicators, and determine the implications of policy changes for future economic activity. ; Willis examines ...

Employment patterns during the recovery: Who are getting the jobs and why?
Employment gains during the recovery have differed sharply depending on workers' level of education, age, and gender. Workers with high levels of education, workers age 55 and older, and men have experienced the strongest employment gains in the recovery. ; Sahin and Willis analyze these employment patterns and find that the patterns appear to reflect two key factors: long-term trends and cyclical fluctuations. The strong employment growth for highly educated and older workers is a continuation of longer term shifts toward a more highly educated workforce and the aging of the baby boom ...

What impact will E-commerce have on the U.S. economy?
In recent years, e-commerce has emerged as the fastest growing sector of the U.S. marketplace. Despite the contraction in the high-tech industry during the recent recession, firms have continued to enter and expand their presence in e-commerce, and consumers have increased the number of purchases made online. E-commerce currently represents a very small share of overall commerce, but it is expected to continue to expand rapidly in coming years. As e-commerce grows, so will its impact on the overall economy. ; The primary route by which e-commerce will affect the economy at large is through ...

The economics of labor adjustment : mind the gap
We study the inferences about labor adjustment costs obtained by the "gap methodology" of Caballero and Engel [1993] and Caballero, Engel and Haltiwanger [1997]. In that approach, the policy function of a manufacturing plant is assumed to depend on the gap between a target and the current level of employment. Using time series observations, these studies reject the quadratic cost of adjustment model and find that aggregate employment dynamics depend on the cross sectional distribution of employment gaps. We argue that these conclusions may not be justified. Instead these findings may ...

Declining Responsiveness at the Establishment Level: Sources and Productivity Implications
This paper studies competing sources of declining dynamism. Evidence shows that an important component of this decline is accounted for by the reduction in the response of employment to shocks in US establishments. Using a plant-level dynamic optimization problem as a framework for analysis, four potential reasons for this decline are studied: (i) a change in exogenous processes for profits, (ii) an increase in impatience, (iii) increased market power, and (iv) increasing adjustment costs. We identify and quantity the contribution of each of these factors building on a simulated method of ...

Real Rigidities, Firm Dynamics, and Monetary Nonneutrality: The Role of Demand Shocks
We propose a parsimonious framework for real rigidities, in the form of strategic complementarities, that can generate real and nominal dynamics and match key features of the data across several literatures. Existing menu-cost models featuring strategic complementarities require unrealistically volatile shocks to idiosyncratic productivity to be consistent with pricing moments. We develop a simple menu-cost model with strategic complementarities along with idiosyncratic productivity and demand shocks that are disciplined by the data. This approach allows us to overcome previous criticism from ...

The economics of labor adjustment: mind the gap
We study inferences about the dynamics of labor adjustment obtained by the "gap methodology" of Caballero and Engel [1993] and Caballero, Engel and Haltiwanger [1997]. In that approach, the policy function for employment growth is assumed to depend on an unobservable gap between the target and current levels of employment. Using time series observations, these studies reject the partial adjustment model and find that aggregate employment dynamics depend on the cross-sectional distribution of employment gaps. Thus, nonlinear adjustment at the plant level appears to have aggregate ...

Mind the (approximation) gap: a robustness analysis
This note continues the discussion of the results reported by Ricardo Caballero and Eduardo Engel (1993), hereafter CE, and Ricardo Caballero, Eduardo Engel, and John Haltiwanger (1997), hereafter CEH, by responding to the results reported in Christian Bayer (2008). Russell Cooper and Jonathan Willis (2004), hereafter CW, find that the aggregate nonlinearities reported in CE and CEH may be the consequence of mismeasurement of the employment gap rather than nonlinearities in plant-level adjustment. Bayer reassesses this finding in the context of the CE model in the case where static employment ...

Magazine prices revisited
This paper examines price adjustment behavior in the magazine industry. In a frequently cited study, Cecchetti (1986) constructs a reduced-form (S,s) model for firms. Cecchetti assumes that a firm's pricing rules are fixed for non-overlapping three-year intervals and estimates the model using a conditional logit specification from Chamberlain (1980). The estimates are inconsistent, however, due to the state-dependent specification of the model. I illustrate the econometric problems in Cecchetti's results through a Monte Carlo exercise and then suggest a method for producing consistent ...
