Assessing New Product Development Practices and Performance: Establishing Crucial Norms

In 1968 and 1982 cross-sectional studies of the conduct and performance of new product development were reported, the wide-ranging results of which have been widely reproduced and cited as norms for product development. Since the more recent study, many changes in the practice and environment of product development have occurred. Albert Page describes the findings of a new cross-sectional study, sponsored by PDMA, which reports on the current status of new product development and updates those commonly referred to norms. On the one hand, this article reports that the state of practice, covering both structure and process, has improved, although there is still substantial room for further improvement. On the other hand, the results for five different measures of firm and program performance indicate these practice improvements have not resulted in notable improvements in the overall performance of the new product development activity within the responding companies.     

The promotion of maize fertiliser packages: A cause of household food insecurity and peasant impoverishment in high rainfall areas of Zimbabwe

Child malnutrition is a continuing problem in Zimbabwe's communal areas. These include some high rainfall areas, which make a contribution to the country's maize surplus during non‐drought years. A survey of farmers and extension workers in four high rainfall communal areas was carried out to investigate the effects of following recommended practices for maize production on household economy and food security.

Thirty‐two per cent of communal farmers had applied all the officially recommended fertiliser to their 1990/91 maize crop, often by obtaining these inputs on credit in lieu of grain sales receipts from the subsequent harvest. Yet. yields were so low that 48 per cent of these farmers would have been unable to retain sufficient grain to satisfy their families’ minimum requirements, if they had reimbursed the full cost of the input credit.

The majority (64 per cent) of farmers had deviatedfrom the recommended practice by adopting ‘low external input strategies’. A key feature of most of these strategies was the substitution of manure for part or all of the recommended fertiliser. In three of the four communal areas studied, this had improved the chances not only of recovering input costs, but also of achieving maize self‐sufficiency.

These results suggest that policy‐makers should shift emphasis from a dependence on costly external inputs to the integration of low levels of fertiliser with a range of more natural methods of soil improvement, in an effort to improve household food security in the communal areas.     

Elections and strategic positioning games

We formalize the interplay between expected voting behavior and strategic positioning behavior of candidates as a common agency problem in which the candidates (i.e., the principals) compete for voters (i.e., agents) via the issues they choose and the positions they take. A political situation is defined as a feasible combination of candidate positions and expected political payoffs to the candidates. Taking this approach, we are led naturally to a particular formalization of the candidates' positioning game, called a political situation game. Within the context of this game, we define the notion of farsighted stability (introduced in an abstract setting by Chwe 1994) and apply Chwe's result to obtain existence of farsightedly stable outcomes. We compute the farsightedly stable sets for several examples of political situations games, with outcomes that conform to real-world observations.Received: 18 May 2001, Accepted: 22 January 2002, JEL Classification: C7, D7, D8Myrna H.

The increased use of trade controls by the industrial countries

The increase in non-tariff barriers to trade in the industrial countries has given rise to much concern. This article attempts to summarize the formal non-tariff measures that have been introduced by the industrial countries to measure roughly how much trade is now affected by them.     

Determinants of Perceptions of Cheating: Ethical Orientation, Personality and Demographics

A sample of 227 business students from the United States and Australia was used to evaluate factors that impact business students' ethical orientation and factors that impact students' perceptions of ethical classroom behaviors. Perceptions of classroom behaviors was considered a surrogate for future perceptions of business behaviors. Independent factors included age, gender, religious orientation, country of origin, personality, and ethical orientation. A number of factors were related to ethical orientation, but only age and religious orientation exhibited much impact upon perceptions of ethical classroom behaviors.     

Do non-citizens affect U.S. Congressional elections?

U.S. citizens against immigration argue that immigrants commit voter fraud and skew election outcomes towards progressive candidates. These arguments have increased in number and severity since the Supreme Court ruled in 2013 that states cannot require photo identification from voters. We examine whether the size of the non-citizen population is related to election outcomes. Previous research indicates that non-citizens sway elections in favour of progressive candidates but only in elections where the victory margin is small. We find no evidence of a relationship between non-citizens and vote outcomes. We find evidence that the percent of the population that is non-white is positively related to percent of votes cast for democratic candidates.
