Knowledge that Transforms

Since recent immigrants tend to earn less than natives, their relative earnings have been adversely affected by an increase in the return to labor market skills over the past three decades. Using longitudinal Social Security records matched to cross-sections of the SIPP and CPS, I estimate the return to skills rose by 41% between 1980 and 1997. This reduced the relative earnings of immigrants who arrived in the 1980s and early 1990s by 10 to 15 percentage points. Examining solely the earnings of recent immigrants may lead to an overly pessimistic picture of their actual labor market skills.

This paper estimates the degree of stickiness in aggregate consumption growth (sometimes interpreted as reflecting consumption habits) for thirteen advanced economies. We find that after controlling for measurement error, consumption growth has a high degree of autocorrelation, with a stickiness parameter of about 0.7 on average across countries. The sticky consumption growth model outperforms the random walk model of Hall (1978) and typically fits the data better than the popular Mankiw (1989) model, though in a few countries, the sticky consumption growth and Campbell-Mankiw models work about equally well.

The production of copyrighted materials varies widely across countries, and how it evolves over time has important policy implications. I propose a simple dynamic model of copyrights and the public domain, which predicts conditional convergence of per capita copyright production among countries. Using book and film production data for the period 1975 to 1995, I test and confirm the model's prediction that copyright-poor countries tend to grow faster than copyright-rich countries in terms of per capita copyright production.

How and why do politicians' preferences about monetary policy differ from the interest rates set by independent central banks? Looking at the European Central Bank (ECB), this paper shows that politicians, on average, favor significantly lower interest rates. Three factors explain the different preferences. First, politicians put relatively less weight on inflation (and more on output) in their preferred monetary policy reaction function. Second, their preferences are affected by political economy motives. Third, different preferences are also, and largely, due to different constituencies, as politicians primarily focus on national economic objectives rather than the euro area as a whole.

This paper offers the first empirical analysis of the impact of adaptation on the boundary of multinational firms. To do so, we develop a ranking of sectors in terms of “routineness” by merging two sets of data: ratings of occupations by their intensities in solving problems from the U.S. Department of Labor's Occupational Information Network and U.S. employment shares of occupations by sectors from the Bureau of Labor Statistics Occupational Employment Statistics. Using U.S. Census trade data, we demonstrate that the share of intrafirm trade tends to be higher in less routine sectors.

We study the link between price points and price rigidity using two data sets: weekly scanner data and Internet data. We find that “9” is the most frequent ending for the penny, dime, dollar, and ten-dollar digits; the most common price changes are those that keep the price endings at “9”; 9-ending prices are less likely to change than non-9-ending prices; and the average size of price change is larger for 9-ending than non-9-ending prices. We conclude that 9-ending contributes to price rigidity from penny to dollar digits and across a wide range of product categories, retail formats, and retailers.

We study how subjects extrapolate simple patterns in financial time series in order to develop a descriptive model of actual agent behavior. The laboratory experiment for this analysis was conducted in Germany and Japan. Statistical analyses indicate considerable similarity in expectations formation across cultures and document that agents' expectations are at variance with the notion of standard trend extrapolation. The paper then proposes a method for computing expectations for any economic time series based on the experimental data. Such pattern-based expectations are shown to explain stock prices and the dynamics of the forward discount on the foreign exchange market.

This paper reports evidence that OECD economies adopting fixed exchange rates in the process of forming the European currency union experienced declines in labor share of income at the industry level. This occurs most sharply among countries that experienced the biggest changes in their exchange rate policy. An implication of New Keynesian sticky price theory is that monetary policy has a first-order impact on labor share through the interaction of business cycle uncertainty and the choice of optimal markups. However, there is also evidence that goods market integration encouraged by the euro had a negative impact on the bargaining position of labor.
