Sources of Entropy in Representative Agent Models

We propose two data‐based performance measures for asset pricing models and apply them to models with recursive utility and habits. Excess returns on risky securities are reflected in the pricing kernel's dispersion and riskless bond yields are reflected in its dynamics. We measure dispersion with entropy and dynamics with horizon dependence, the difference between entropy over several periods and one. We compare their magnitudes to estimates derived from asset returns. This exercise reveals tension between a model's ability to generate one‐period entropy, which should be large, and horizon dependence, which should be small.     

DOES TRADE ADJUSTMENT ASSISTANCE MAKE A DIFFERENCE?

The U.S. Trade Adjustment Assistance (TAA) program provides workers who have lost their jobs due to increased trade with income support and training, job search, and relocation benefits. This paper uses data collected by the Department of Labor on TAA beneficiaries to provide the most recent econometric evaluation of the effectiveness of the TAA program. Summary statistics suggest that the TAA program successfully targets displaced workers who have a greater difficulty finding new employment. However, using propensity score matching techniques we find that while the required training component of the program improves the employment outcomes of beneficiaries, on average the TAA program has no discernible impact on the employment outcomes of the participants.

THE SOVIET PATH TO ECONOMIC GROWTH: A COMPARATIVE ANALYSIS

Considerable attention has been devoted in the past to the methodological issues involved in the measurement and explanation of economic growth. Following the method pioneered by Denison and applied by him to the United States and Western Europe, comparative studies have been made of various other countries; that for Japan is of special interest. The present paper extends the analysis to the Soviet Union. In order to preserve comparability, the analysis follows the Denison methodology exactly, and compares the results with those for the United States, Northwest Europe, and Japan.
