Action Teams That Work

A growing awareness of workplace hazards and identification of airborne contaminants, coupled with a changing safety and health regulatory environment, created an unexpected demand for new and innovative respirators in the early 1980s. 3M's Occupational Health and Environmental Safety Division broke new ground by taking the team concept further than ever before in the company. The division's Action Teams successfully designed, built and introduced products in less than half the time it would have taken previously. Robert Hershock, Charles Cowman and Douglas Peters describe how 3M learned important lessons about team selection, training, performance and motivation, the importance of project sponsors, and the role of middle management.

Price rigidities and institutional variations in markets with posted prices

Summary Standard laboratory posted-offer markets respond slowly and incompletely to demand shocks. In these one-sided markets, where sellers control the setting of prices, very little information is transmitted via the process of exchange. For this reason, traders have trouble distinguishing randomness in their own experience from changes in market fundamentals. This paper reports the results of twelve laboratory markets conducted to assess whether some common variants to standard posted-offer rules can correct the adjustment deficiences. Although discounting, multiple postings and excess demand information all improve performance, we find that response remains poor, and efficiencies low.Support for this research was provided by the National Science Foundation (SBR 9319842 and SBR 9320044), and the University of Virginia Bankard Fund.

AN EVALUATION OF PROCESS‐ORIENTED SUPPLY CHAIN MANAGEMENT FRAMEWORKS

Supply chain management (SCM) is implemented by integrating corporate functions using business processes within and across companies. Several process‐oriented frameworks for SCM have been proposed but only two of these provide sufficient detail to enable implementation. We evaluate the Supply‐Chain Operations Reference (SCOR) framework and The Global Supply Chain Forum (GSCF) framework using four criteria and identify their relative strengths and weaknesses.     

Horatio Alger Meets the Mobility Tables

The question of how entrepreneurship relates to income mobility is cogent given the current public debate about the sources of income inequality and mobility in United States society. We examine how experience with entrepreneurship has affected an individual's place in the earnings distribution. Our basic tack is to follow individuals' positions in the income distribution over time, and to see how their mobility (or lack thereof) was affected by involvement with entrepreneurship. Our main finding is that for low-income individuals there is some merit to the notion that the self-employed moved ahead in the earnings distribution relative to those who remained wage earners. On the other hand, for those at the upper end of the earnings distribution, those who became self-employed often advanced less in the earnings distribution than their salaried counterparts.     

A Golden Formula in Neoclassical‐Growth Models with Brownian‐Motion Shocks

In the paper, a Golden Formula, which does not depend on the specification of production and preference functions, is established to reveal that time‐average of the growth rate of optimal capital accumulation will converge to a constant, which is endogenously determined by relevant parameters, almost surely. The Golden Formula naturally implies surprisingly interesting and also intrinsic economic relations between some important macroeconomic variables; for example, it serves as a direct bridge between the modified Golden Rule and the modified Ramsey Rule. Furthermore, it indeed subsumes and hence substantially extends the classical Golden Rule in deterministic theory.

Anonymity in Computer-Mediated Communication: More Contrarian Ideas with Less Influence

Anonymity is thought to be an important means for ensuring a free exchange of ideas by encouraging the expression of minority viewpoints. However, we suggest that anonymity’s reduction in awareness of others potentially affects the expression and interpretation of comments that are made during a discussion. In particular, anonymity will increase the likelihood that comments will be made that are contrary to the majority opinion while at the same time decreasing the effect that those contrary arguments have on other group member’s opinions. This paper reports experimental results showing that anonymity led to more overall participation in discussions of ethical scenarios. However, equality of member participation did not differ between anonymous and member-identified groups, and anonymous groups had significantly higher awareness-related comments. This leads to the conclusion that additional participation in anonymous groups accommodates reduced awareness rather than reflecting the increased participation of normally reticent group members. In addition, anonymity led to more arguments in support of questionable behavior, suggesting that the freeing effects of anonymity apply to the social desirability of arguments. Finally, there was less change in opinion under conditions of anonymity than when comments were identified, suggesting that anonymous arguments have less influence on opinions than identified comments.     

Lending technologies,lending specialization,and minority access to small-business loans

We investigate minority access to small-business loans using a probit model of loan application denial that recognizes two loan types (line-of-credit loans and non-line-of-credit loans) made by two lender types (commercial banks and nonbank financial institutions). We estimate our model on data from the 1998 Survey of Small Business Finances. We find evidence consistent with minority equal access to bank credit lines and nonbank non-line-of-credit loans in highly competitive loan markets; in less competitive markets we find evidence consistent with unequal access to these loans. We also find evidence consistent with unequal minority access to bank non-line-of-credit loans, regardless of loan market competitiveness. Our findings differ from previous research which treats small-business loans as a homogenous product and finds evidence consistent with unequal minority access to small-business loans generally. We argue that the existence of multiple small-business lending technologies and loan specialization by lenders account for our findings and demonstrate the need to treat small-business loans as a heterogeneous product when investigating equal access to small-business credit.
