This paper examines the 205 insolvent thrifts that were resolved in 1988 and assesses the cost savings obtained by selling 179 of the institutions through assisted acquisitions rather than liquidating them. It is hypothesized that the cost savings were determined by factors related both to the future viability of the acquired institution and the particulars of the deal arranged by the Federal Home Loan Bank Board and the Federal Savings and Loan Insurance Corporation. The added value by selling a thrift is determined primarily by the level of core deposits obtained by the acquired thrift. However, the branch structure and purchased mortgage-servicing rights should also add franchise value to the firm. In addition to these factors, the analysis accounts for the tax benefits and other regulator forbearances associated with the deals. Other characteristics of the deals are also considered. It is found that core deposits, tax benefits, purchased mortgage-servicing rights, average branch size, and type of acquirer, as well as some other factors, were significant determinants of the cost savings obtained through selling an institution rather than liquidating it.  相似文献

We apply a discrete choice approach to model the empirical behaviour of the Federal Reserve in changing the federal funds target rate, the benchmark of short‐term market interest rates in the US. Our methods allow the explanatory variables to be nonstationary as well as stationary. This feature is particularly useful in the present application as many economic fundamentals that are monitored by the Fed and are believed to affect decisions to adjust interest rate targets display some nonstationarity over time. The chosen model successfully predicts the majority of the target rate changes during the time period considered (1994–2001) and helps to explain strings of similar intervention decisions by the Fed. Based on the model‐implied optimal interest rate, our findings suggest that there is a lag in the Fed's reaction to economic shocks during this period.

A survey was conducted in Lilongwe city urban markets in Malawi, to assess the quality of cooking oil used for frying potato chips. Purposive sampling was performed to come up with respondents who were using vegetable oils. A stratified random sampling was used to select the 32 informal food processors who were interviewed using a structured questionnaire. Oil samples were collected from the most commonly used brand of oil. Fifteen respondents were selected and these were divided into three categories of five: those who were not reusing the oil, those who were reusing the oil and those who were preparing potato chips and chicken in the same oil, for chemical analysis. The preliminary results showed that while the majority (59.4%) of the informal food processors discarded the oil after 1 day, 3.1% discarded it after 4 days and another 12.5% after 3 days. A larger proportion of the respondents (40.6%) used the leftover oils at home, 37.5% kept it in oil bottles, 3.1% kept it in plastic papers for reuse the following day. Also, most respondents (57%) indicated dark colour as the sign of oil deterioration, 29% discarded the oil after noticing foam formation while 8.2% and 6.1% said they discarded the oil after noticing a bad smell and food absorbing the oils respectively. A physical observation of the various oils showed that for most of the respondents (34%), the oils were dark brown in colour, in 22%, the oils were slightly dark brown and 16%, the oils were brown. Foam formation was noticed in 13% of the respondents. It was also noted that 91% of the respondents had not been trained or briefed of food quality and safety issues. A chemical analysis of the oils showed high values of free fatty acids (range, 0.84–1.4112 compared with 0.42 in the fresh oil) and peroxide values (range 14.7–16.6 compared with 9.0 in the fresh oil). It may be concluded that the oils being used by the informal food processors in Malawi are of poor quality and so the foods cooked in them may be a health hazard to the consumers and the processors themselves. Although this work in ongoing, it may be recommended at the outset that the health department of the city assemblies should inspect these oils for the good health of the consumers.  相似文献

This paper analyzes a point in-point out inventory investment under price uncertainty. The optimal quantity is determined by maximizing the expected value of the investor's risk preference function, which is a function of profit. Using an exponential risk preference function, the adjustment in the optimal quantity stemming from a change in the interest rate is investigated. The main conclusion is that the sign of the adjustment depends both on how profit is expressed and on the type of price distribution applied. Contrary to what is assumed in conventional managerial control practices, a rise in the interest rate might lead to an increase in the optimal quantity when present value serves as a measure of profit.  相似文献

Human capital raises rural incomes, but this effect is swamped by higher returns to human capital in urban markets. This leads to "brain drain" from rural areas. Populations grow more rapidly in rural counties that have a diversified employment base. Farm population grows faster (or declines more slowly) in counties with relatively high farm income, and nonfarm populations grow faster in counties with relatively high nonfarm income. However, higher farm incomes lead to slower nonfarm population growth and vice versa. Rural county government services financed by local taxes or debt have neutral or negative effects on population growth.  相似文献

Managerial Equity Ownership and the Demand for Outside Directors   总被引:1,自引:0,他引:1  
This paper examines the linkage between the use of outside directors and managerial ownership. We conjecture there are two linkages: the standard incentive‐alignment demand for monitoring when managers own little stock and an entrenchment‐amelioration demand when managerial stock ownership is high. As a consequence, we predict the association between managerial ownership and board composition will be nonlinear (U‐shaped if the entrenchment effect is sufficiently pronounced). Using UK data, we find that both quadratic and logarithmic models outperform the simple linear relationship assumed in prior research and that the substitution between managerial ownership and board composition is stronger than hitherto supposed.  相似文献

The truncated Poisson regression model is used to arrive at point and interval estimates of the size of two offender populations, i.e. drunk drivers and persons who illegally possess firearms. The dependent capture–recapture variables are constructed from Dutch police records and are counts of individual arrests for both violations. The population size estimates are derived assuming that each count is a realization of a Poisson distribution, and that the Poisson parameters are related to covariates through the truncated Poisson regression model. These assumptions are discussed in detail, and the tenability of the second assumption is assessed by evaluating the marginal residuals and performing tests on overdispersion. For the firearms example, the second assumption seems to hold well, but for the drunk drivers example there is some overdispersion. It is concluded that the method is useful, provided it is used with care.  相似文献

This article presents the results of a survey of professors in accounting departments in Australia. Professors ranked Australian accounting departments on a variety of research, teaching and staffing attributes, on contributions to the accounting profession and provided an overall ranking of the departments. Overall rankings placed the University of Queensland and the University of New South Wales a close first and second, followed by the University of Sydney, the University of Melbourne, the University of Western Australia, and Monash University. Analysis of the separate sub-dimensions of performance shows that it is variations in respondents' perceptions of research-related performance of departments which accounts for variation in the overall ranking. We also asked the professors for their views on several issues facing accounting educators and those who recruit accounting graduates. Most believed that there should be more breadth in undergraduate accounting courses than is currently the case. However, most felt that recruiters would prefer degree structures to remain as they are. There was overwhelming consensus that it was reasonable to expect ethics to be taught in accounting programs; that the Australian Securities Commission should not replace corporate management in the appointment of auditors; and that accounting standards should not be written to force very conservative depictions of profitability and financial position. There was disparity of opinions on whether auditors ought to be expected to foreshadow financial distress; whether the audit role should be expanded to explicitly embrace fraud detection; and whether financial reports should be understandable to the lay person.  相似文献
