A model of adverse selection and moral hazard in agri‐environmental schemes is developed based on the input quota mechanism of Moxey et al. (Journal of Agricultural Economics, Vol. 50, (1999) pp. 187–202) and Ozanne et al. (European Review of Agricultural Economics, Vol. 28, (2001) pp. 329–347), rather than the input charge mechanism of White (Journal of Agricultural Economics, Vol. 53, (2002) pp. 353–360), but the variable fine of the latter rather than the fixed fine assumed by Ozanne et al. (European Journal of Agricultural Economics, Vol. 28, (2001) pp. 329–347) is used. Incentive‐compatible contracts, including the optimal probabilities of detection (and, therefore, monitoring frequencies and costs) for more and less efficient farmers, are identified. It is shown that the input charge and input quota approaches lead to identical outcomes – in terms of abatement levels, compensation payments, monitoring costs and probabilities of detection – confirming the equivalence of input quotas and input charges under asymmetric information. It is also shown that the optimal contracts are independent of the risk preferences of farmers with regard to being caught cheating. 相似文献

This study examines price transmission asymmetries in Vidarbha's (India) cotton supply chain from 2002 to 2012. The analysis takes account of thresholds in price adjustments toward their long‐run equilibrium. The first stage considers the price dynamics between international and Indian domestic cotton prices. The second stage considers price transmission from domestic to farm gate cotton prices in Vidarbha. Results from the first stage indicate that Indian and international cotton markets are well‐integrated. In contrast, the second stage reveals significant threshold‐type nonlinearities as well as asymmetries in price transmission between domestic and farm gate prices. The short‐run dynamics suggest that the pass‐through from domestic to farm gate prices is larger when domestic prices decrease than when they increase. Moreover, back of the envelope calculations suggest that the loss in revenue for a typical farmer from a decrease in domestic price is larger than the gains from an increase in domestic price of the same magnitude. The implication is that traders benefit from price fluctuations at the expense of farmers. Evidence from fieldwork in Vidarbha suggest that asymmetries revealed in this analysis may be linked to trader's market power and inadequate market information among farmers. 相似文献

Changes in agriculture have led to faculty reductions and shifts in research funding sources for agricultural economics departments. Agricultural economics journals have been affected by these developments, since they must compete for authors and readers in a changed market. One strategy regional journals have used to address these changes has been renaming to names that suggest the journals publish a broader range of applied economics research. This article examined changes in the distribution of authorship of the Review of Agricultural Economics , the Journal of Agricultural and Resource Economics , and the Journal of Agricultural and Applied Economics before and after their renaming. 相似文献

This commentary, written during the Society's fiftieth anniversary year, describes its origins and early activities and traces the evolution of its Conferences and the Journal of Agricultural Economics. It comments on the professional and non-professional achievements of the Society to date, and briefly, considers the future. Emphasis is given to the Society itself rather than to individual members although a series of appendices list many of the individuals who have been especially involved in the conduct of the Society's affairs. 相似文献

This special issue is special in two major dimensions: the papers range intentionally over a much wider spectrum of social and natural science approaches and disciplines than is normal for the Journal of Agricultural Economics; and, the articles relate to ongoing research rather than completed work. These reflections, perhaps peculiar to a practicing applied economist and policy analyst, concentrate on the lessons to be learned and messages to be heard from the RELU programme, both by those engaged on the programme's research portfolio, and by other researchers. 相似文献

Several studies in the literature have argued that price transmission in vertically‐related markets is imperfect, i.e. that farm input price changes are not fully passed‐through to the final product price. Market power, notably oligopoly, is presumed to be the principal source of imperfect price transmission. To date, the impact of oligopsony (buyer) power on the degree of price transmission has not been evaluated using a formal theoretical model. Moreover, neither has the combination of oligopoly and oligopsony despite the fact that its influence has been formally acknowledged in both the UK and some European food markets. This paper makes a contribution to the literature by developing a model of price transmission where both oligopoly and oligopsony power co‐exist and where industry technology is assumed to be characterised by variable input proportions. It shows that taking the degree of price transmission in a perfectly competitive market as a benchmark, oligopoly and oligopsony power do not necessarily lead to imperfect price transmission, although they can. Indeed, they may counteract each other's impact on the degree of price transmission. The key to these outcomes is to be found in the functional forms for retail demand and farm supply. 相似文献

R. G. Gregory's article on the effects of mineral discoveries on the Australian economy (Australian Journal of Agricultural Economics, August 1976) has attracted much attention. While the partial-equilibrium nature of his model has enabled it to be absorbed readily, it has the usual theoretical limitations of such analyses. Allowing for general equilibrium repercussions, but still accepting his general assumptions, some of Gregory's conclusions regarding the impact of new mineral discoveries require modification or extension:
- (a) Although production of goods other than minerals can be expected to decline, the production of some goods in this category may rise;
- (b) A social gain is still possible even if outputs of other goods do not change;
- (c) While the price of non-tradeable goods can be expected to rise, production of non-tradeables may increase or decrease.

The present paper extends the existing literature on vertical price transmission and cost pass‐through by investigating the impact of product differentiation. We apply distance‐measures of product differentiation to a specific product market (yoghurt) within one country (Germany). Results from a panel‐error‐correction model for 30 products sold in 432 stores over a period of 312 weeks suggest that product differentiation explains a significant share of differences in cost pass‐through rates: more differentiated products command higher prices and are characterised by lower equilibrium cost pass‐through rates as well as more sluggish price adjustment. 相似文献

Perfect farm‐retail price transmission sometimes is taken to mean an elasticity of price transmission (EPT) equal to 1. We show that this definition is inconsistent with Gardner's (1975) model. We also show that the absolute marketing margin (defined as the difference between the retail price and farm price) responds differently to shifts in retail demand, input supply, and technical change in the marketers’ production function than does the relative marketing margin (defined as the ratio of the retail price to the farm price). The empirical implications of these results are discussed in some detail. 相似文献

Hubbard and Philippidis Journal of Agricultural Economics (2001) Vol. 52, pp. 87–95] employ the standard Global Trade Analysis Project (GTAP) computable general equilibrium (CGE) model to analyse the impact of the bovine spongiform encephalopathy (BSE)‐induced ban on exports of UK beef. This note extends that study in four ways: (i) the dynamic GTAP model is employed to characterise long‐run savings–investment behaviour more correctly; (ii) the effect of the foot‐and‐mouth disease (FMD) outbreak of 2001 is included; (iii) an allowance is made for different levels of recovery in consumer confidence; and (iv) the impact analysis is now compared through time with a ‘no‐ban’ baseline. Long‐run comparisons after removal of the ban suggest that its legacy may continue for some time. However, because of the remedial safeguards and assurances offered in the wake of the BSE and FMD crises, there is a possibility that exports and outputs increase. Nevertheless, the economy‐wide impacts are negligible in both the short and the long run. 相似文献

In this paper, we examine the effects of shocks in agricultural output, production material price and production price on China's food price using panel data of 26 provinces for the period 2004 Q1–2015 Q4. Employing a heterogeneous panel structural vector autoregressive (SVAR) model, we identify the causal flows between the endogenous variables via directed acyclic graphs method. The empirical results from impulse response functions and variance decompositions suggest sizeable cross‐province variations. The main driving force of food price is the price inertia shock, rather than the agricultural output or the vertical chain of price transmission shocks. The findings support the view that price expectation is the key shifter of food price. Moreover, the shocks in the vertical chain of price transmission are only weakly linked to food price. Our findings are robust to an alternative panel SVAR model identified via Cholesky decomposition. 相似文献

2004 has been a good year for the Journal and the last under the Nottingham editorial team. The target of a four‐month average turnaround for submissions has been achieved for the second year in succession and record use has been made of the on‐line version of the JAE ‐which currently attracts around 165 full‐text paper downloads per month. The release of the 2003 citations data from the Institute of Scientific Information shows that JAE articles are cited more than ever before, although the change in the JAE's publication dates implemented in 2002 have inadvertently reduced its ‘impact factor’ score, which has slipped from 1st to 7th since 2001. Reversion to the original publication cycle will correct this apparent decline. On the other two measures JAE is ranked 2nd and 3rd in the Agricultural Economics and Policy category. Preparations are on‐going to ensure a smooth hand‐over of Editorship in April 2005, when Professor David Harvey and colleagues from the University of Newcastle upon Tyne take over the JAE. The handover will coincide with the adoption of an electronic submission and review system and a partnership with Blackwell Publishing. 相似文献

This article provides an introduction to the special feature on agriculture‐related issues in the emerging economies of Brazil, Russia, India and China (BRIC) contained in this issue of Journal of Agricultural Economics. The special feature is motivated by the increased interest which these countries have received since the turn of the millennium and by the significance of agriculture in their development. It considers economic and social development in BRICs, their integration in world agricultural trade as well as environmental concerns. This article presents key figures on economic, social and agricultural features in BRICs and compares them across countries. A synthesis of the articles included in the special feature is provided by highlighting the selection of topics likely to be crucial for further development across BRICs. 相似文献

The pricing behaviour of India's high value agricultural and food exporters in their major destination markets is examined using a pricing‐to‐market (PTM) model for noncompetitive and exchange rate related pricing behaviour. The analysis was undertaken in a context where India is showing high commodity concentration in agricultural trade. The econometric analysis employed is panel corrected standard errors (PCSE) estimation technique. The results indicated evidence of a greater degree of imperfect competition either through price discrimination across destinations or through imperfect exchange rate pass‐through. The analysis of exchange rate effects showed that the local currency price stabilization by the Indian exporters were more prominent than the amplification of exchange rates. The analysis of the asymmetric effects of exchange rates on export prices showed that in most cases the depreciation of Indian rupee had a greater impact than the appreciation. Moreover the results showed that the exchange rate pass‐through is sensitive to the kind of exchange rate index utilised. In our analysis we found that the commodity specific exchange rate better predicts the pricing to market behaviour in most cases. 相似文献

This article extends the multi‐period agri‐environmental contract model of Fraser (Journal of Agricultural Economics, Vol. 55 , (2004) pp. 525–540) to include a more realistic specification of the inter‐temporal penalties for non‐compliance, and therefore of the inter‐temporal moral hazard problem in agri‐environmental policy design. It is shown that a farmer has an unambiguous preference for cheating early over cheating late in the contract period based on differences in the expected cost of compliance. It is then shown how the principal can make use of this unambiguous preference to target monitoring resources intertemporally, and in so doing, to encourage full contract duration compliance. 相似文献

This paper examines the criticism of contingent valuation put forth by Blamey, Common and Quiggin ( Australian Journal of Agricultural and Resource Economics , 1995, vol. 39, pp. 264–288). They argue that households have consistent preferences over private goods but not jointly consistent preferences over public and private goods and, hence, contingent valuation cannot uncover meaningful responses for the valuation of public goods. In this paper we argue that the motives that are manifested in choices for public goods can be explained in two ways. One is the model of the citizen, proposed by Blamey et al . (1995). The second is a model of neoclassical preferences with altruism. Given these alternative and competing explanations of choices for public goods, what matters is whether they imply differences in willingness to pay for public goods. We provide statistical evidence from a contingent valuation study of the control of deer in the USA that there is no difference in willingness to pay between those who profess 'citizen' or altruistic preferences and the rest of the presumably purely private respondents. 相似文献

A recent paper by Hardaker et al. (The Australian Journal of Agricultural and Resource Economics, 48, 2004a, 253) and book by Hardaker et al. (Coping with Risk in Agriculture, 2004b) describe a procedure for determining an efficient set from among a set of random alternatives. This procedure, called stochastic efficiency with respect to a function (SERF), is claimed to make the same assumption concerning the risk aversion measures as does stochastic dominance with respect to a function (SDRF). This is claim is incorrect. SERF imposes an additional requirement on the risk aversion measures of the decision makers. Both procedures assume a lower and an upper bound on risk aversion, but SERF also assumes that all risk aversion measures are of the same functional form as these lower and upper bound functions. This additional strong requirement on risk preferences implies that the efficient set identified under SERF is usually smaller than that identified using SDRF. 相似文献

Review and change have recently characterised governmental price and income policy for agriculture in the U.K., E.E.C. and U.S. This study of the U.S. Agricultural Act of 1970, effective for the major crops for the next three years, is a follow-up to an earlier article in this Journal on the policy of the 1960's. An analysis is made of the new Act's development, provisions, and probable consequences. Although voluntary land retirement, compensatory payment policy is continued, a ‘set-aside’ modification is likely to have implications for either government costs or farmer incomes. The slightly lower supports and higher payments contrasts with the apparent current direction of European policy. Consideration is given to current negotiations and policy differences among these three trading groups. 相似文献
