Subsidization of S&Ls under the flat-rate deposit insurance system: Some empirical estimates

This study provides some estimates of the magnitude of the subsidies extracted by S&L holding companies under the present flat-rate deposit insurance system. The results suggest that the flat-rate deposit insurance system induces substantially uneven and inequitable distribution of subsidies among thrift institutions. The analysis of the thrift institutions' asset volatilities over the 1966–1988 period does not support the claim that deregulation of the industry has led to a systematic increase in risk-taking in the industry. On the other hand, we find that a large fraction of the asset volatilities are attributable to firm-specific investment policies and that the risk of the institutions' assets change considerably over time. Taken as a whole, the results suggest that switching to a risk-based deposit insurance system would be economically more efficient than the present scheme. We provide some recommendations for policy changes that can increase the efficacy of risk-based insurance by increasing the level of monitoring by depositors and the financial markets.     

Adverse selection as an explanation of credit rationing and different lender types

An adverse selection model is utilized to demonstrate that informational asymmetry may make it wealth optimal for the financial intermediary (FI) to credit ration and to rationalize the existence of different lenders in the credit market. The crucial assumption is that borrowers differ in their tolerance for a lender-imposed default penalty, the severity of which also varies with the lender. The credit rationing portion proves that the FI will: 1) be forced by a binding regulatory constraint to overinvest in capital; 2) ration its worst risk class borrowers; 3) establish its optimal loan interest rate on the basis of the average quality of its loans and the interest rate elasticity of the borrower demand in its best risk category; and 4) decrease the total loan volume and increase the loan interest rate due to an increase in the capital requirement, but the effect on the default risk quality of its loan portfolio is ambiguous. The existence result is that if a lender has a high default penalty, he can charge a lower rate and attract only “good” borrowers, i.e., heterogeneous lender types encourage the screening of borrowers and vice versa.     

Estimating the variance of the ratio estimator for theMidzuno-Sen sampling scheme

Summary The problem of estimating the variance of the ratio estimator for theMidzuno-Sen sampling scheme is further studied in this paper. Sufficient conditions are derived for which the suggested variance estimator is always positive definite.

Code and conduct in French cuisine: Impact of code changes on external evaluations

We study the effects of organizational code‐preserving and code‐violating changes on external evaluations by third parties—an essential but under‐studied strategic outcome. We define code‐preserving changes as a variation in the firm's product range that preserves the social code within which the firm positions its offering. By contrast, a code‐violating change corresponds to a variation in the product range that breaks with past codes and embraces another social code. Our analyses of French haute cuisine restaurants show that code‐preserving changes and code‐violating changes have positive effects on external evaluations. Both effects decline with prior evaluations received by the organization, but only the effect of code‐violating changes is reduced with age. Moreover, external evaluations improve when restaurants undertake more code‐preserving changes than their direct competitors but decline when they make more code‐violating changes than competitors. These results enable us to derive implications for research on strategic change, strategic groups, and strategic social positioning. Copyright © 2007 John Wiley & Sons, Ltd.     

PRICE HETEROGENEITY AND "REAL" INEQUALITY: A CASE STUDY OF PRICES AND POVERTY IN RURAL SOUTH INDIA

This paper, based upon a case-study of three Indian villages, studies whether households within the same market pay different prices for identical goods. It is found that not only are unit prices for food heterogeneous, but that the poor pay more for the same goods than the rich. This is because liquidity constraints force poorer households to purchase goods in small quantities and consequently subject them to quantity premiums. Household specific index numbers are used to adjust nominal incomes to real values and it is found that Gini coefficients of real incomes are between 12 percent to 23 percent greater than the Gim for nominal incomes. An econometric analysis of the determinants of prices shows that incomes are negatively correlated with prices, as is family size, but that the amount of land owned shows a positive relationship.     

Agricultural Supply Response: A Survey

This paper surveys the literature on agricultural supply response to prices in developing countries. Empirical estimates of elasticities depend both on the methodology adopted and on country-specific factors relating to technology, economic structure and macro constraints. The paper seeks to establish some general conclusions on supply responsiveness within these limitations. Supply response to output prices at the aggregate and at the crop levels is considered first. Crop-specific acreage elasticities range between zero and 0.8 in the short run while long-run elasticities tend to be higher — between 0.3 and 1.2. Yield elasticities are smaller and less stable than acreage elasticities. Clearly, inter-crop pricing can be relied upon to effect shifts in the commodity composition of agricultural output. Evidence also suggests that supply elasticities vary systematically with such factors as price and yield risks, multiple-cropping, the importance of the crop, farm incomes, farm size, tenancy and literacy. The most controversial and important aspect of supply response is the effect on aggregate agricultural output of agriculture's terms of trade. Conventional time-series estimates range from 0.1 to 0.3. A major cross-country study reports an aggregate elasticity as high as 1.66. It is argued that cross-country estimates are apt to exaggerate aggregate responsiveness while time-series studies underestimate it somewhat. For LDCs, a tentative range of 0.4 to 0.5 seems plausible. Hence, the distributive effects of the terms of trade are likely to be more significant than the allocative effects. Asian evidence shows that only a third of the inter-country differences in fertilizer use can be attributed to fertilizer price policies. Provided new technologies and infrastructure are in place, fertilizer subsidies can help in technology diffusion and in overcoming credit constraints. The choice between price supports and input subsidies will depend on a variety of country- or situation-specific factors. Nevertheless, a significant general factor favoring price supports is that they can more easily be coupled with price stabilization goals than input subsidies. Though sparse, the available evidence on the response of marketed surplus suggests that price policy is not a reliable instrument for regulating inter-sectoral trade.     

Market Segment Response Through Field Experimentation

A key assumption underlying segmentation studies is that marketing efforts have differential effects on market segments. This question was investigated in the context of a field experiment involving enlistment in the armed forces. Approximately 8000 completed questionnaires administered at various stages in the US Navy enlistment recruiting process were collected at two points in time, corresponding to a pre- and post-experimental intervention. Attitudinal data were analysed to identify meaningful segments. Differential responses of market segments to advertising and recruiter changes were found, providing direction for evaluation of, and changes in, the creative component of advertising.     

Linking Order Fulfillment Performance to Referrals in Online Retailing: An Empirical Analysis

Referral management for online retailers is a strategically important activity, as referrals offer a highly cost‐effective method of customer acquisition. In fact, online customers mention referrals as the second‐most common reason for choosing to shop at a particular retailer, second only to search engine suggestions. However, while online retailers are able to improve their visibility on search engines through focused keyword insertions, they are often unable to pinpoint the drivers of referral behavior among their customers. The current research examines the relationship between two key dimensions of online retailing: order fulfillment cycle times and referral behavior. Employing a theory of customer appraisal and empirically testing the ensuing model using structural equation modeling, we find that excellent order fulfillment is instrumental in generating referrals for the online retailer, even after factoring in product quality.
