Determinants of off‐farm work and its effects on farm performance: the case of Norwegian grain farmers

Limited attention has been given in the literature to the impact of off‐farm work on farm performance. More knowledge about the determinants of part‐time farming and its effects on farm performance could help policymakers to introduce better targeted rural development policies. The aim in this article is to fill part of the above‐mentioned gaps by analyzing factors that influence the choices of off‐farm work by either the farmer alone or jointly by both the farmer and partner; and simultaneously examining how off‐farm work influences farm performance. These analyses were based on an unbalanced panel data set from Norwegian grain farms during 1991 to 2005. Among the determinants of off‐farm work hours, we found that, in addition to demographic, time trend, and some regional effects, there was a significant negative effect of farm output on farmers' off‐farm work hours. The production function results revealed that off‐farm work had a positive effect on farm output, at first increasing but then decreasing with increase in hours spent in off‐farm work. Furthermore, our analysis revealed no systematic effect of off‐farm work on farm technical efficiency.     

Endogenous Pollution Havens: Does FDI Influence Environmental Regulations?*

We suggest a novel perspective on the relationship between the stringency of environmental policies and foreign direct investment (FDI). We develop a political economy model with imperfect product market competition where local and foreign firms jointly lobby the local government for a favorable pollution tax. FDI is found to affect environmental policy, and the effect is conditional on the local government's degree of corruptibility. If the degree of corruptibility is sufficiently high (low), FDI leads to less (more) stringent environmental policy, and FDI thus contributes to (mitigates) the creation of a pollution haven. Our empirical results using panel data from 33 countries support the predictions of the model.     

Social norms and the fertility transition

This paper provides a norm-based explanation for two features of the fertility transition that have been observed in many different settings: the slow response to external interventions and the wide variation in the response to the same intervention. Most societies have traditionally put norms into place to regulate fertility. When the economic environment changes, individuals gradually learn through their social interactions about the new reproductive equilibrium that will emerge in their community. This characterization of the fertility transition as a process of changing social norms is applied to rural Bangladesh, where norms are organized at the level of the religious group and interactions rarely cross religious boundaries. Consistent with the view that changing social norms are driving changes in reproductive behavior in these communities, we find that the individual's contraception decision responds strongly to changes in contraceptive prevalence in her own religious group within the village whereas cross-religion effects are entirely absent. Local changes in reproductive behavior occur independently across religious groups despite the fact that all individuals in the village have access to the same family planning inputs.     

Collective vs. individual lobbying

This paper presents a menu-auction model in which firms lobby the government to make an environmental regulation less burdensome. In this lobbying game, industrial interests are opposed by an environmental interest group. We compare political outcomes under two institutional arrangements. In the first, firms must join an organization that represents the interests of the industry. In the second, firms would lobby the government individually. The two arrangements result in strikingly different equilibrium outcomes. Only a small fraction of firms join the lobby group under collective lobbying, but all firms participate in lobbying activities when there is no such group. Thus, an attempt by firms to solve the apparent collective action problem through coordination would effectively backfire. The reason is that coordination among firms would increase the leverage available to the government, to demand high political contributions. We also evaluate the desirability of the two lobbying regimes from the private perspective of individual firms, and from the perspective of society as a whole. This permits us to evaluate possible restrictions on lobbying activities.     

THE LONG‐TERM ECONOMIC CONSEQUENCES OF AGRICULTURAL MARKETING LEGISLATION IN SOUTH AFRICA

The marketing of most agricultural products in South Africa was subject to intervention by statutory bodies over a period of some 60 years. At the time of the promulgation of the first legislation there was a vigorous debate on the predicted economic effects; in 1983 one of the architects of these instruments published a justification in these pages, followed in 2000 by a “post‐mortem,” which confirmed most of the negative predictions that had been made. The purpose in this article is to revisit this debate and to provide a first assessment of the long‐term impacts of the legislation.     

Explaining National Border Effects in the QUAD Food Trade

Using a ‘structural’ gravity‐like model, this paper first provides estimates of bilateral ‘border effects’ in food trade among the QUAD countries (the US, Canada, Japan and the EU) at the ISIC (International Standard Industrial Classification) four‐digit level (18 food sectors). It then investigates the underlying reasons for border effect, assessing the role played by policy barriers (tariffs, non‐tariff barriers to trade (NTBs) and domestic support) with respect to barriers unrelated to trade policy, such as information‐related costs, cultural proximity and preferences. In contrast to several previous findings, our results show that policy trade barriers, especially in the form of NTBs, are part of the story in explaining national border effects. Interestingly, in all country pair combinations, NTBs significantly dominate the trade reduction effect induced by tariffs. However, results show that elements linked to information‐related costs and consumer preferences matter a great deal in explaining the magnitude of border effects. These findings have implications for the economic and welfare‐related significance of national borders.     

On the Consumer Value of Diversity: An Application to Italian Fish

This article investigates the consumer value of diversity both conceptually and empirically. It proposes a measure of diversity value based on a benefit function. It shows that the consumer value of diversity can arise from complementarity and/or convexity effects among consumer goods. The usefulness of the approach is illustrated by an application to fish in Italy. The investigation illustrates the role played by both convexity and complementarity in the valuation of diversity. The empirical evidence shows the importance of dynamics. It also documents how the value of diversity varies depending on the bundles considered.     

The impact of auction characteristics on prices of agricultural products traded online: evidence from cherries

This article provides an empirical study on the relationship between auction characteristics and prices using a data set on cherry sales from the online auction site Yahoo! Kimo. Using three alternative measures of the dependent variable, results indicate that reputation variables have a statistically important association with auction prices. The extent of reputation's impact on prices varies substantially depending on the model specification and estimation technique. The article highlights the effectiveness of a nonlinear specification for both measuring and interpreting the underlying reputation variables. The use of a “Buy It Now” option, size, and country of the origin is correlated with prices at statistically significant levels. Several econometric concerns regarding the empirical modeling strategy are discussed.

Technical Efficiency of Rice Farms in Different Agroclimatic Zones in the Philippines: An Application of a Stochastic Metafrontier Model*

Rice producers in the Philippines operate in spatially diverse physical environments that are largely beyond their control. We decompose total factor productivity into technical efficiencies and environment–technology gap ratios across four climatic zones for selected years from 1996/1997 to 2005/2006 using farm‐level panel data. Results show surprisingly little interzonal and intertemporal variation in productivity. It appears that Philippine rice producers have been able to adapt their crop management strategies sufficiently to suit their particular agroclimatic conditions. However, after an increase in the first 5 years of the study period, mean environment–metatechnology gap ratios stagnated in the second 5 years. The metafrontier does not appear to have substantially shifted outwards over the whole period, suggesting that rice producers achieved little technological progress and increased total factor productivity.
