Efficiency in agricultural production: the case of peasant farmers in eastern Paraguay

This paper contributes to the productivity literature in developing country agriculture by quantifying the level of efficiency for a sample of peasant farmers from Eastern Paraguay. A stochastic efficiency decomposition methodology is used to derive technical, allocative and economic efficiency measures separately for cotton and cassava. An average economic efficiency of 40.1% for cotton and of 52.3% for cassava is found, which suggests considerable room for productivity gains for the farms in the sample through better use of available resources given the state of technology. Gains in output through productivity growth have become increasingly important to Paraguay as the opportunities to bring additional virgin lands into cultivation have significantly diminished in recent years. No clear strategy to improve farm productivity could be gleaned from an examination of the relationship between efficiency and various socioeconomic variables. One possible explanation for this finding is the existence of a stage of development threshold below which there is no consistent relationship between socioeconomic variables and productivity. If this is the case, then our results suggest that this sample of Paraguayan peasants are yet to reach such a threshold. Hence, improvements in educational and extension services, for example, would be needed to go beyond this threshold. Once this is accomplished, additional productivity gains would be obtained by further investments in human capital and related factors.

Culture and age as moderators in the corporate reputation and loyalty relationship

This study investigates the moderating role of culture and relationship age in the relationship between customer-based corporate reputation (CBR) and customer loyalty using data from two service contexts (retailing and fast-food restaurants) in three countries (France, the U.K., and the U.S.) that differ with regards to two cultural values—uncertainty avoidance and time orientation. Results suggest that CBR has similar effects on affective and intentional loyalty in all three countries. However, culture interacts with relationship age, such that relationship age magnifies the effect of CBR in France, while relationship age suppresses CBR's effect in the U.K. and the U.S. The authors provide explanations for these effects based on cultural theories. Managerial and research implications are developed.     

Investigating mediators between corporate reputation and customer citizenship behaviors

Recent corporate reputation research focuses on customers as an important stakeholder group for whom firm reputation matters. The authors hypothesize that customer-based corporate reputation (CBR) may affect customer citizenship behaviors (CCB) and that both commitment and loyalty mediate the CBR-CCB relationship. The tests of the hypotheses use a sample of 583 service customers who evaluate the reputation of service firms. These results suggest that commitment and loyalty mediate the relationship between CBR and one type of CCB, that is, helping the company. The authors discuss the implications for marketing research and practice.     

Diminishing effects of location? Some evidence from Swiss municipalities, 1950–2000

This paper analyzes how location has affected, in the second half of the twentieth century, the population growth of 2889 municipalities in Switzerland. The analysis demonstrates the temporal relativity of location attributes, even for small territorial divisions, such as the Swiss cantons. However, we also show that, both absolute and relative location attributes have weakened over time as population growth predictors, apparently due to improving road infrastructures, and growing motorization. The study has been made possible by a detailed historical population and accessibility database available for Swiss municipalities. To the best of our knowledge, no database of such scope and quality is available for any other European country.     

Are we nice(r) to nice(r) people?—An experimental analysis

We experimentally investigate whether individuals can reliably detect cooperators (the nice(r) people) in an anonymous decision environment involving “connected games.” Participants can condition their choices in an asymmetric prisoners’ dilemma and a trust game on past individual (their partner’s donation share to a self-selected charity) and social (whether their partner belongs to a group with high or low average donations) information. Thus, the two measures of niceness are the individual donation share in the donation task, and the cooperativeness of one’s choice in the two games. We find that high donors achieve a higher-than-average expected payoff by cooperating predominantly with other high donors. Group affiliation proved to be irrelevant.

Macroeconomic Fluctuations and Bank Lending: Evidence for Germany and the Euro Area

Abstract. This paper analyzes the dynamic response of loans to the private sector and of economic activity to aggregate supply, demand and monetary policy shocks in Germany and the euro area based on a standard macroeconomic VAR using sign restrictions to identify the structural shocks. The main results of this analysis are that (i) with the exception of the response to the supply shock in Germany, the response of loans to the three macroeconomic shocks is rather weak and in most cases insignificant; (ii) the 2000–05 credit slowdown and weak economic performance in Germany were primarily driven by adverse supply shocks; and (iii) the marked slowdown in credit creation in Germany over this period actually represents a realignment of the outstanding stock of loans with its deterministic level. In order to assess the role of bank lending in the transmission of macroeconomic shocks, we further perform counterfactual simulations and analyze the dynamic responses of German loan subaggregates in order to test the distributional implications of potential credit market frictions. These exercises do not indicate that credit market frictions play an amplifying role in the transmission of macroeconomic fluctuations.     

Development similarities in urban clusters: Evidence from a spatial analysis of Israel''s urban system

The effect of geographic proximity on the similarity of development rates exhibited by urban localities in Israel is investigated. The analysis is carried out in three stages. During the first stage, Moran's I measure of spatial autocorrelation is used, indicating that the spatial autocorrelation of development rates drops as inter-town distances increase. In the second stage, the impact of explanatory variables (population size, remoteness, etc.) is tested using both Ordinary Least Squares (OLSs) and Spatial Lag Models (SLMs). The analysis indicates that inter-town proximity is a significant factor that helps to improve regression fits. Lastly, during the third step of the analysis, the spatial association of development rates is studied separately for centrally located and peripheral towns. The analysis points out that proximity effects appear to be stronger in the periphery.     

The Intellectual Structure of Product Innovation Research: A Bibliometric Study of the Journal of Product Innovation Management, 1984–2004

Product innovation research has matured substantially in the last two decades. A great deal of knowledge has been produced on various aspects of the discipline, so it is of interest to assess the state of the art the scientific community has reached in this discipline and the route it has taken. This perspective is investigated through a bibliometric study of the Journal of Product Innovation Management (JPIM), arguably the most important specialized journal on this topic. The work reviews all journal paper contributions in JPIM from 1984 to 2004 in determined time frames, assesses the citations contained in these papers, identifies how the citations are related to the various topics of production innovation research (topic‐related citation variety, topic‐related citation consistency, variation in topic‐related citation pattern), and offers a retrospective examination of the evolution of the field. The overall analysis of citations shows that most papers in JPIM cite at least one of the top 50 works identified by this study. This testifies to the strong impact of the most influential works on the intellectual structure of product innovation research. The observed citation pattern suggests that the top 50 papers gained influence in product innovation research either because they represent a relevant contribution on a fundamental topic that already has been authoritatively studied or because they investigate in a relevant manner a new topic. The paper suggests that JPIM might benefit in its aim to consolidate its position as one of the top academic business journals if published papers increasingly drew on the most influential works to inform their research design and explicitly stated the theoretical underpinnings they draw on in their research design. Overall, the analysis of the subperiods (1984–1988, 1989–1993, 1994–1998, and 1999–2004) provides evidence for the maturation of new product innovation research. Books covering a wide range of topics are replaced by journal papers addressing a specific topic; over time, specific topics emerge and become influential for the discipline's intellectual structure; papers published in JPIM augment their methodological rigor and increasingly address contingency factors. The paper also notes that obtaining relevance for JPIM authors constitutes a necessary condition for being considered by management researchers at large as an influential contribution to product innovation research.
