WHY ADOPT INTEGRATED CROP PRODUCTION? A PERSPECTIVE FROM THE FRENCH FRUIT SECTOR
Are changes in consumer demand and concentration in food retail altering market structures so that integrated production practices like IPM and ICM will become not only widely adopted but essential if growers want to maintain access to markets? Data on the European fresh produce sector are analyzed, applying Randall Bartlett's economic theory of power. The authors conclude that if current trends continue, then the answer to the question posed could soon be, "yes."Crop Production/Industries,
On analytic properties of Meixner-Sobolev orthogonal polynomials of higher order difference operators
In this contribution we consider sequences of monic polynomials orthogonal
with respect to Sobolev-type inner product where is the Meixner linear operator,
, , , and
is the forward difference operator , or the backward difference
operator .
We derive an explicit representation for these polynomials. The ladder
operators associated with these polynomials are obtained, and the linear
difference equation of second order is also given. In addition, for these
polynomials we derive a -term recurrence relation. Finally, we find the
Mehler-Heine type formula for the case
STRATEGIC CHOICES IN PRODUCE MARKETING: ISSUES OF COMPATIBLE USE AND EXCLUSION COSTS
Fresh produce suppliers in Europe and the United States use a mix of price and non-price marketing strategies. This paper shows that these strategies create, using Mancur Olson's terms, two collective goods: overall consumer confidence in the market's ability to deliver credence attributes, and overall consumer satisfaction with the experience attributes of fresh produce. The characteristics of these two collective goods, i.e., their compatible use and high costs of exclusion, influence the costs, effectiveness, and nature of the marketing strategies of firms. This paper presents examples from the fresh produce industries of Europe and the U.S. to show how compatible-use and high-exclusion costs influence firm strategies. It concludes that there are unavoidable interdependencies that create a need for collective action -- a need that will increase as consumer and retailer demand for quality attributes in fresh produce increases.Demand and Price Analysis, Marketing,
Unraveling the World-Wide Pollution Haven Effect
This paper contributes to the debate on the existence of pollution haven effects by systematically measuring the pollution content of trade (measured by the polluction content of imports (PCI)) and decomposing it into three components: a 'deep' (i.e. unrelated to the environmental debate) component and two components (factor endowments and environmental policies) that occupy centerstage in the debate on trade and the environment. The decomposition is carried out for 1986-88 for an extensive data set covering 10 pollutants, 48 countries and 79 ISIC 4-digit sectors. Illustrative decompositions presented for 3 of the 10 pollutants in the data set indicate a significant pollution haven effect and highlight the role of factor endowments in each region's PCI. However, because the bulk of trade is intra-regional with a high North-North share, these effects are small relative to the 'deep' determinants of the worldwide pollution content of trade.trade and the environment; pollution haven
Unraveling the worldwide pollution haven effect
This paper contributes to the debate on the existence of pollution haven effects by systematically measuring the pollution content of trade (measured by the pollution content of imports, PCI) and decomposing it into three components-a"deep"component (unrelated to the environmental debate but including variables traditionally present in the gravity model) and two components (factor endowments and environmental policies) that occupy center stage in the debate on trade and the environment. The decomposition is carried out for 1986-88 for an extensive data set covering 10 pollutants, 48 countries, and 79 ISIC 4-digit sectors. Illustrative decompositions presented for three of the 10 pollutants in the data set indicate a significant pollution haven effect which increases the PCI of the North because of stricter environmental regulations in the North. At the same time, the factor endowment effect decreases the PCI of the North as the North is relatively well-endowed in capital and pollution-intensive activities are also capital-intensive. On a global scale, because the bulk of trade is intraregional with a high North-North share, these effects are small relative to the"deep"determinants of the worldwide pollution content of trade. In sum, although the impact has been stronger on vertical (North-South) trade flows, differences in factor endowments and environmental policies have only marginally affected the pollution content of world trade during the 1986-88 period.Environmental Economics&Policies,Water and Industry,Brown Issues and Health,Transport Economics Policy&Planning,Water Resources Assessment
Governance and Development
In this paper we discuss whether or not `governance' is an important source of variation in development experiences. We draw four main conclusions. First, governance is best thought of a sub-set of `institutions' and as such emphasis on governance is consistent with much recent academic work. Nevertheless, governance is a quite vague rubric which it is difficult to unbundle. Second, the governance of a society is the outcome of a political process and as such is closely related to the literature on the political economy of development. Third, improving governance necessitates understanding the nature of the entire political equilibrium. Finally, an important research frontier is understanding the forces that create or impeded endogenous changes in governance.
Unraveling the World-Wide Pollution Haven Effect
This paper contributes to the debate on the existence of pollution haven effects by systematically measuring the pollution content of trade (measured by the polluction content of imports (PCI)) and decomposing it into three components: a âdeepâ (i.e. unrelated to the environmental debate) component and two components (factor endowments and environmental policies) that occupy centerstage in the debate on trade and the environment. The decomposition is carried out for 1986-88 for an extensive data set covering 10 pollutants, 48 countries and 79 ISIC 4-digit sectors. Illustrative decompositions presented for 3 of the 10 pollutants in the data set indicate a significant pollution haven effect and highlight the role of factor endowments in each regionâs PCI. However, because the bulk of trade is intra-regional with a high North-North share, these effects are small relative to the âdeepâ determinants of the worldwide pollution content of trade.Trade and the Environment, Pollution Haven
Unravelling the Worldwide Pollution Haven Effect
This paper tackles the âpollution havenâ argument by estimating the pollution content of imports (PCI). The PCI is then decomposed into three components: (i) a âdeepâ component (i.e. traditional variables unrelated to the environmental debate); (ii) a factor endowment component and (iii) a âpollution havenâ component reflecting the impact of differences in environmental policies. The estimation is carried out for 1987 for an extensive data set covering 10 pollutants, 48 countries and 79 ISIC 4-digit sectors. Decompositions based on cross-section econometric estimates suggest a significant pollution haven effect which increases the PCI of the North because of stricter environmental regulations in the North. At the same time, the factor endowment effect lowers the PCI of the North, as the North is relatively well-endowed in capital and pollution-intensive activities are capital intensive. On a global scale, because the bulk of trade is intra-regional with a high North-North share, these effects are small relative to the âdeepâ determinants of the worldwide PCI. In sum, differences in factor endowments and environmental policies have only marginally affected the PCI of world trade at the end of the eighties.Trade and The Environment, Pollution Haven Effect, Factor Endowment Effect
Global Manufacturing SO2 Emissions: Does Trade Matter?
A growth-decomposition (scale, technique and composition effect) covering 62 countries and 7 manufacturing sectors over the 1990-2000 period shows that trade, through reallocations of activities across countries, has contributed to a 2-3 percent decrease in world SO2 emissions. However, when compared to a constructed counterfactual no-trade benchmark, depending on the base year, trade would have contributed to a 3-10 percent increase in emissions. Finally adding emissions coming from trade-related transport activities, global emissions are increased through trade by 16 percent in 1990 and 13 percent in 2000, the decline being largely attributable to a shift of dirty activities towards cleaner countries.embodied emissions in trade, environment, growth decomposition, transport, world trade
