We examine the relation between firm diversification and asymmetric information empirically using metrics drawn from the market microstructure literature. We find that the average diversified firm in our sample has somewhat less severe asymmetric information problems than a similarly constructed portfolio of stand-alone firms chosen to approximate the segments of the conglomerate. We also find that the information asymmetry of diversified firms is very similar to that of individual focused firms that approximate the conglomerates along several dimensions not including industry composition. We conclude that greater diversification is not on average associated with increased asymmetric information.

This paper analyzes how the implicit difference in time horizons between refugees and economic immigrants affects subsequent human capital investments and wage assimilation. The analysis uses the 1980 and 1990 Integrated Public Use Samples of the Census to study labor market outcomes of immigrants who arrived in the United States from 1975 to 1980. I find that in 1980 refugee immigrants in this cohort earned 6% less and worked 14% fewer hours than economic immigrants. Both had approximately the same level of English skills. The two immigrant groups had made substantial gains by 1990; however, refugees had made greater gains. In fact, the labor market outcomes of refugee immigrants surpassed those of economic immigrants. In 1990, refugees from the 1975-1980 arrival cohort earned 20% more, worked 4% more hours, and improved their English skills by 11% relative to economic immigrants. The higher rates of human capital accumulation for refugee immigrants contribute to these findings.

This paper surveys the measurement of trade costs: what we know and don't know but may usefully attempt to learn. Partial and incomplete data on direct measures of costs go with inference on implicit costs from trade flows and prices. Total trade costs in rich countries are large. The ad valorem tax equivalent is about 170 percent when pushing the data hard. Poor countries face even higher trade costs. There is a lot of variation across countries and across goods within countries, much of which makes economic sense. In our survey, theory provides interpretation and perspective and suggests improvements for the future. Some new results are presented to properly apply and interpret gravity theory and handle aggregation.

This paper considers how the presence of a speculative investor, who bets on a firm's future earnings report, affects how the firm's management manipulates that report. We examine the influence of the speculator's information on earnings management behavior, quality of reported earnings, and stock price efficiency. We also provide predictions for, and interpretations of, short‐window event studies and long‐window association studies.

Both debt covenants and federal monitoring restrict banks’ discretion. We examine whether banks substituted monitoring for covenants by investigating debt issues of 105 banks between 1979 and 1984, a period when monitoring increased. We hypothesize that bank shareholders take advantage of the intersection between debt covenants and regulatory monitoring to reduce agency costs. We find a decrease in the number of debt issues containing such covenants and the total debt subject to such covenants. We find no such decrease during the same period for a sample of non-banking firms, or for banks during a subsequent period.

To evaluate early embryo development, 248 good to excellent bovine morulae were cultured in Ham's F-10 medium, supplemented with 10% steer serum, uterine flushings from Days 6, 10 or 15 following estrus (0.01, 0.1, 1.0 and 10% protein; 64 mg protein/ml), and 1.0% uterine flushings and 10% steer serum. Final development scores for embryos in steer serum were significantly higher (range across experiments was: 4.06 to 4.37) than for embryos cultured in uterine flushings alone (-0.23 to 0.52). Treatment means were not different (P >0.05) when 10% steer serum was added to 1.0% uterine flushings. A higher percentage of embryos in 10% steer serum (92%) than in 10% steer serum plus 1.0% uterine flushing from Day 6 (33%), Day 10 (45%) and Day 15 (50%) developed to hatched blastocysts. Embryos cultured in 1.0% Day 6 uterine flushings plus 10% steer serum required more time to attain the early blastocyst and blastocyst stages, while embryos in 1.0% Day 15 uterine flushings and 10% steer serum developed at the same rate as controls to the expanded blastocyst stage, but hatched sooner (72.8 vs 96.5 h). These results suggest substance(s) in uterine secretions can have inhibitory and stimulatory influences on early bovine embryo development.

We investigate factors associated with firms' decisions in 2002 and early 2003 to recognize stock‐based compensation expense under Statement of Financial Accounting Standards (SFAS) No. 123. We find that the likelihood of SFAS 123 expense recognition is significantly related to the extent of the firm's participation in capital markets, the private incentives of top management and members of the board of directors, the level of information asymmetry, and political costs. Although recognizing firms have significantly smaller SFAS 123 expense, we find no significant incremental relation between recognition likelihood and SFAS 123 expense magnitude after controlling for other factors that we expect explain the recognition decision. We also find positive and significant announcement returns for earlier announcing firms, particularly those stating that increased earnings transparency motivates their decision.

We examine optimal capital allocation and managerial compensation in a firm with two investment projects (divisions) each run by a risk-neutral manager who can provide (i) (unverifiable) information about project quality and (ii) (unverifiable) access to value-enhancing, but privately costly resources. The optimal managerial compensation contract offers greater performance pay and a lower salary when managers report that their project is higher quality. The firm generally underinvests in capital and managers underutilize resources (relative to first-best). We also derive cross-sectional predictions about the sensitivity of investment in one division to the quality of investment opportunities in the other division, and the relative importance of division-level and firm-level performance-based pay in managerial compensation contracts.

Firms incur restructuring charges as a result of actions intended to improve their operating performance. However, there is little evidence on whether restructuring charges are associated with improved performance. We examine a sample of firms reporting restructuring in 1991‐93 and find that the restructuring firms' earnings increase over the levels immediately before restructuring. Compared with a control sample of firms that report no restructuring, the restructuring firms improve their earnings and operating income, but evidence for improvements in cash flow from operations is mixed. In regression analysis, we find that restructuring charges are significantly positively associated with post‐restructuring changes in earnings relative to the restructuring year, but this association is largely driven by firms with multiple restructurings and firms reporting losses in the restructuring year. We find no association between restructuring charges and post‐restructuring changes in earnings relative to the year before restructuring. Restructuring charges are significantly positively associated with post‐restructuring changes in operating income and cash flow from operations for firms with multiple restructurings. In summary, restructuring charges are associated with improved earnings, but our results suggest that restructuring in the early 1990s did not necessarily guarantee improved operating performance.
