After controlling for loan quality, liquidity, capitalization, and output mix, per unit bank operating costs are found to vary significantly across Asian countries and over time. Further analysis reveals that the country rankings of per unit labor and physical capital costs are highly correlated, suggesting that there exist systematic differences in bank operating efficiency across Asian countries. However, this measure of operating efficiency is found to be unrelated to the degree of openness of the banking sector. Asian bank operating costs were found to decline from 1992 to 1997, indicating that banks were improving their operating performance over time. Since 1997, the run-up in operating costs coincided with the Asian financial crisis, suggesting that banks were incurring additional costs in dealing with their problem loans while output was declining simultaneously. Moreover, the labor cost share is found to decline significantly between 1997 and 1999, indicating that banks were able to cut their labor force after the financial crisis but were less flexible to reduce physical capital input. Furthermore, significant differences in labor cost share are detected across countries, suggesting that different countries have different bank production functions. The variations in labor cost share are significantly positively related to the country’s financial services wage rate, suggesting that banks using relatively more labor in a particular country is due to the labor force productivity, rather than labor being cheap.

This paper examines the effects of a series of events leading up to the deregulation of deposit interest rates in Hong Kong on the market value of banks. All the evidence suggests that banks earned rents from deposit interest rate rules (IRRs) and deregulation would lower these rents and hence bank market values. On average, the total abnormal return due to interest rates deregulation was around negative 4%. There is some evidence that large banks and banks with high deposit-to-asset ratio suffered a bigger drop in value, suggesting that these banks enjoyed a bigger subsidy under the IRRs.

This paper examines old and new evidence on the predictive performance of asset prices for inflation and real output growth. We first review the large literature on this topic, focusing on the past dozen years. We then undertake an empirical analysis of quarterly date on up to 38 candidate indicators (mainly asset prices) for seven OECD countries for a span of up to 41 years (1959 - 1999). The conclusions from the literature review and the empirical analysis are the same. Some asset prices predict either inflation or output growth in some countries in some periods. Which series predicts what, when and where is, however, itself difficult to predict: good forecasting performance by an indicator in one period seems to be unrelated to whether it is a useful predictor in a later period. Intriguingly, forecasts produced by combining these unstable individual forecasts appear to improve reliably upon univariate benchmarks.
Statement of Financial Accounting Standards No. 109 (SFAS No. 109) allows firms to use their discretion to set arbitrarily high valuation allowances against deferred tax assets. Firms can then later use these "hidden reserves" to manage earnings. Our evidence indicates that most banks do not record a valuation allowance to manage earnings, but rather to follow the guidelines of SFAS No. 109. However, if the bank is sufficiently well capitalized to absorb the current‐period impact on capital, then the amount of the valuation allowance increases with a bank's capital. In later years, bank managers adjust the valuation allowance to smooth earnings. The magnitude of the discretionary adjustment increases with the deviation of unadjusted earnings from the forecast or historical earnings.

This paper presents evidence of anomalies in internet firms’ stock returns surrounding their quarterly earnings announcements. There is a general runup in prices in the days prior to the earnings announcements, followed by a price reversal lasting for several days. The magnitude of the market-adjusted returns associated with these price movements exceeds 11 percent over a 10-day period. We find little evidence to suggest that these returns can be explained either by the earnings news disclosed or by risk changes. Additional analyses suggest that these return patterns are driven, at least in part, by price pressure.

Between 1984 and 2001, the share of nonelderly adults receiving Social Security Disability Insurance income (DI) rose by 60 percent to 5.3 million beneficiaries. Rapid program growth despite improving aggregate health appears to be explained by reduced screening stringency, declining demand for less skilled workers, and an unforeseen increase in the earnings replacement rate. We estimate that the sum of these forces doubled the labor force exit propensity of displaced high school dropouts after 1984, lowering measured U. S. unemployment by one-half a percentage point. Steady state calculations augur a further 40 percent increase in the rate of DI receipt.

This paper investigates depository institutions' decisions whether or not to impose surcharges (direct usage fees) on nondepositors who use their ATMs. In addition to documenting patterns of surcharging, we examine motives for surcharging, including both direct generation of fee revenue and the potential to attract deposit customers who wish to avoid incurring surcharges at an institution's ATMs. Consistent with expectations, we find that the probability of surcharging increases with both the institution's share of market ATMs and the time since surcharging was first allowed in the state, and decreases with increasing local ATM density. Further, we find evidence consistent with the use of surcharges to attract deposit customers who are new to the local banking market, but we find no evidence that larger banks use surcharges as a means to attract existing customers away from smaller local competitors.

This study investigates whether higher input use per stay in the hospital (treatment intensity) and longer length of stay improve outcomes of care. We allow for endogeneity of intensity and length of stay by estimating a quasi-maximum-likelihood discrete factor model, where the distribution of the unmeasured variable is modeled using a discrete distribution. Data on elderly persons come from several waves of the National Long-Term Care Survey merged with Medicare claims data for 1984–1995 and the National Death Index. We find that higher intensity improves patient survival and some dimensions of functional status among those who survive.
We study the daily and intradaily cross‐sectional relation between stock returns and the trading of institutional and individual investors in Nasdaq 100 securities. Based on the previous day's stock return, the top performing decile of securities is 23.9% more likely to be bought in net by institutions (and sold by individuals) than those in the bottom performance decile. Strong contemporaneous daily patterns can largely be explained by net institutional (individual) trading positively (negatively) following past intradaily excess stock returns (or the news associated therein). In comparison, evidence of return predictability and price pressure are economically small.
