Canadian fruit and vegetable markets were significantly impacted by the spread of the novel coronavirus SARS-CoV-2 (and COVID-19 disease), beginning in March 2020. Due to the closure of restaurants, bars, and schools, produce growers and distributors were forced to shift supplies almost entirely from the foodservice to the retail channel. Shippers reported labor and logistical constraints in making the change, but the fresh produce supply chain remained robust. In the long term, we expect lasting changes in consumers’ online food-purchasing habits, heightened constraints on immigrant labor markets, and tighter concentration in fresh produce distribution and perhaps retailing.  相似文献

Policy “reform” in agricultural markets is often associated with less government regulation and expenditures, or a shift towards more efficient interventions. The European Union (EU) adopted major policy changes for processed fruits and vegetables in 2001 and again in 2008, and we employ a simulation model to examine the effects of the three policy regimes in place before and after each of the changes. Our analysis incorporates the heterogeneity of processing firms in the EU and considers how they responded to the different policy regimes. Simulation results indicate that the EU subsidies increased EU tomato production by 3.8% for the regime that began in 2008 and 9.1% for the regime that began in 2001 compared to no subsidies. The policy regime that was in place from 2001 through 2007 led to the greatest distortions in global processing tomato markets, in part because it directed more of the benefits to EU growers and less to EU processors and consumers. Thus changes in 2001 “reformed” policy by redistributing gains within the EU, while changes in 2008 “reformed” policy by reducing distortions in global markets.  相似文献

The paper analyses the dynamics of some duopoly output games involving the Cournot, Market-Share and Nichol strategies. The model assumes linear price and cost functions and supposes that outputs are adjusted instantaneously at discrete time intervals. For all games considered, equilibrium is either reached after a finite number of moves or a stable approach to equilibrium occurs as t → ∞. In fact, apart from a few uninteresting cases, arising from the oversimplified form of the Market-Share strategy, all equilibrium points lie on specified parts of the firms' Cournot loci.  相似文献

In horticultural markets, trade barriers often apply to the processed products whereas domestic support applies to farm-produced raw commodities. Here we assess the effects of such trade barriers and domestic support by simulating the effects of policy reform on global processing tomato markets, which are faced with modest processed product tariffs and high domestic support in the European Union (EU). Both protection and EU subsidy drive down world welfare, but we find that reducing import tariffs for tomato products would yield greater effects on markets and larger welfare impacts outside Europe than would reductions in EU domestic support.  相似文献

The outcome of the Common Agricultural Policy, with its “managed” market for farm products, has been high prices and surplus production, the disposal of which incurs a heavy expenditure on market support. At the same time, structural changes have been relatively insignifcant in the absence of a coherent E.E.C. programme, and, farms remain predominantly small and uneconomic. Financial and social pressures have compelled the Comission of the E.E.C. to admit that the Common Agricultural Policy needs to be radically re-appraised. In December 1968, far-reaching proposals, the so-called “Mansholt Plan”, were put forward by the Comission. This paper outlines and compares the structural policies of E.E.C. member States, and considers their impact upon the structure of farming. An assessment is also made of the measures included in the Mansholt Plan and in subsequent Community proposals designed to raise farmers' living standards and to reduce the cost of the Common Agricultural Policy.  相似文献

The relation between equilibria of output-setting and price-setting duopolies is investigated using the Inverse Function Theorem. The region that equilibria of the former occupy in relation to equilibria of the latter is found. A minimum of assumptions about the market functions are made.  相似文献
