Economic valuation of the vulnerability of world agriculture confronted with pollinator decline

There is mounting evidence of pollinator decline all over the world and consequences in many agricultural areas could be significant. We assessed these consequences by measuring 1) the contribution of insect pollination to the world agricultural output economic value, and 2) the vulnerability of world agriculture in the face of pollinator decline. We used a bioeconomic approach, which integrated the production dependence ratio on pollinators, for the 100 crops used directly for human food worldwide as listed by FAO. The total economic value of pollination worldwide amounted to €153 billion, which represented 9.5% of the value of the world agricultural production used for human food in 2005. In terms of welfare, the consumer surplus loss was estimated between €190 and €310 billion based upon average price elasticities of − 1.5 to − 0.8, respectively. Vegetables and fruits were the leading crop categories in value of insect pollination with about €50 billion each, followed by edible oil crops, stimulants, nuts and spices. The production value of a ton of the crop categories that do not depend on insect pollination averaged €151 while that of those that are pollinator-dependent averaged €761. The vulnerability ratio was calculated for each crop category at the regional and world scales as the ratio between the economic value of pollination and the current total crop value. This ratio varied considerably among crop categories and there was a positive correlation between the rate of vulnerability to pollinators decline of a crop category and its value per production unit. Looking at the capacity to nourish the world population after pollinator loss, the production of 3 crop categories - namely fruits, vegetables, and stimulants - will clearly be below the current consumption level at the world scale and even more so for certain regions like Europe. Yet, although our valuation clearly demonstrates the economic importance of insect pollinators, it cannot be considered as a scenario since it does not take into account the strategic responses of the markets.     

IMPACT OF AGRICULTURAL COOPERATIVES ON SMALLHOLDERS’ TECHNICAL EFFICIENCY: EMPIRICAL EVIDENCE FROM ETHIOPIA

Using household survey data from Ethiopia, this paper evaluates the impact of agricultural cooperatives on smallholders’ technical efficiency. We used propensity score matching to compare the average difference in technical efficiency between cooperative member farmers and similar independent farmers. The results show that agricultural cooperatives are effective in providing support services that significantly contribute to members’ technical efficiency. These results are found to be insensitive to hidden bias and consistent with the idea that agricultural cooperatives enhance members’ efficiency by easing access to productive inputs and facilitating extension linkages. According to the findings, increased participation in agricultural cooperatives should further enhance efficiency gains among smallholder farmers.     

Supply side inflation persistence

We explore the role of the cost channel in accounting for inflation persistence in the New Keynesian model with Calvo pricing. Hump-shaped responses of inflation to monetary shocks are obtained under purely nominal rigidities.     

THE IMPORTANCE OF REPUTATION IN AWARDING PUBLIC CONTRACTS

ABSTRACT * :  The main economic literature emphasizes that the efficiency of the awarding procedure depends on the contractual rules, especially those regarding firm's remuneration. In this work we show the existence of a reverse link: when the enforcement of contractual terms is imperfect, the rules of the awarding mechanism can help to improve the efficiency of the contractual relationship. In some circumstances, awarding rules based only on bids are not able to deal with the problem of opportunistic behaviour during the execution of the contract. Our model points out that the public administration can incentivize the contractor's fairness by considering not only competitors' bids, but also their different reputation.     

Mark-ups, economies of scale and the role of knowledge spillovers in OECD industries

Using R&D-based models of economic growth as a foundation, this paper argues that market-driven knowledge creation is necessarily linked as an engine of productivity growth to economies of scale and market-power. A cost function and factor demand model is applied to a cross-country industry data set to study market-power, economies of scale and the role of knowledge in an integrated approach. Empirical results reveal the presence of market-power and economies of scale in all of the industries investigated. R&D and spillovers explain some of the productivity growth observed. Spillovers are identified as an external source of economies of scale.     

Is a Conservative Central Banker a (Perfect) Substitute for Wage Coordination?

In a monetary union, macroeconomic policies are strongly associated with externalities that imply the need for coordination. However, if coordination is not complete, it might be unable to cope with the externalities. This paper investigates different solutions for internalizing policy externalities. In particular, we compare wage coordination to the conservative central banker solution, which the recent literature has found able to impose wage moderation on labor unions. We also discuss some issues related to labor flexibility reforms as a solution for the unemployment problem.     

THE RISE AND DECLINE OF ECONOMIC POLICY AS AN AUTONOMOUS DISCIPLINE: A CRITICAL SURVEY

After Adam Smith's statement of market virtues, the process of gestation of economic policy as a rational set of rules for public agenda has been rather slow. Until not so long ago, economic policy as a discipline was often confined to prescribing practical rules intended to explain technical procedures of government intervention. Economic policy– as a coherent and to some extent autonomous discipline–only emerged in the late 1950s in Scandinavia, the Netherlands and Italy, when solid foundations indicating not only microeconomic but also macroeconomic market failures and a theory about the conditions for policy effectiveness and design were consistently developed. This paper intends to explain the reasons for the emergence of the discipline, the circumstances that favoured its diffusion, the reasons for its apparent setback and some factors that could facilitate its diffusion in the next years
