Analysis of the technical efficiency of state rubber farms in Vietnam

This study entails an analysis of the technical efficiency of natural rubber production by state farms in Vietnam. A time-varying stochastic frontier production function model for unbalanced data is estimated for 33 farms. Individual farm technical efficiencies are reported and discussed. One of the main results concerns the bimodal distribution of technical efficiency indices. A few farms operate near the production frontier while the bulk operate well away from the frontier. Some implications are drawn from the results as a guide to future policy research work in the rubber industry in light of recent moves by the Vietnamese government towards economic reform.     

Technical Inefficiency and Production Risk in Rice Farming: Evidence from Central Luzon Philippines*

There have been many previous studies of technical inefficiency in rice production in the Philippines, but none has focused simultaneously on production risk and technical inefficiency at the farm level. Rice production is inherently risky because of the heterogeneous production environment. In this study, we analyze technical inefficiency in a rainfed lowland rice environment in Central Luzon using a stochastic frontier production function with a heteroskedastic error structure. An 8‐year panel dataset collected from 46 rainfed rice farmers was used to estimate flexible functional specifications. Over the whole period, the average technical efficiency was found to be 79 percent. Results indicate that there is a high degree of variability in technical efficiency estimates, which can be attributed to the instability of farming conditions in the rainfed lowland environment. Mean output was signifificantly influenced by area planted to rice, labor and the amount of fertilizer used. Consequently, these inputs were found to be risk‐increasing, whereas herbicide was found to be a risk‐reducing input.     

The accuracy of international trade data

International trade data are of great importance to planners in the Third World as well as to academic researchers. They are often considered to be the best economic series available. Just how accurate are these data really?     

The Effect of Off-farm Work on the Intensity of Agricultural Production

Changes in agricultural production methods have been associated with environmental pressure and a loss of natural habitats. This paper explores the extent to which farmer participation in off-farm work (an increasing phenomenon in most developed countries) changes the intensity of agricultural input use focusing, in particular, on fertilizer and crop protection product use. A sample selection model that accounts for both unobserved heterogeneity between farms and the potential simultaneity between farm operations and hours worked off-farm is estimated for 2,419 farms in England and Wales. The econometric evidence indicates that the input intensity of products which have well-established links to environmental damage can increase as well as decrease. The results suggest that that fertilizer intensity may decline as off-farm labor increases while the use of crop protection per hectare increases as off-farm work increases.     

FARM HOUSEHOLD PRODUCTION IN THE PRESENCE OF RESTRICTIONS ON DEBT: THEORY AND POLICY IMPLICATIONS

In this paper a two period life cycle model of the farm household is constructed allowing for production and restrictions on debt in which the consumption and production decisions of the farm household are simultaneous. It is shown that the farm household's production responses to exogenous changes may be qualitatively different to that predicted by the profit-maximising model when all markets are perfect. In particular, when the household is debt constrained, ‘perverse’ output effects are possible with output increasing in response to output price decreases. Further, for such households, compensation payments will have production effects. Finally, the financial situation of the farm has an impact on production for debt constrained farms.     

Explaining rising regionalism and failing multilateralism: consensus decision-making and expanding WTO membership

The beleaguered progress of the Doha Development Agenda of the World Trade Organisation (WTO) presents something of a puzzle for economic theory: if multilateralism is an effective forum for liberalisation (as it has been in the past), then why have the current round of talks faltered amid the proliferation of preferential trade agreements (PTAs)? This paper builds a ‘hub and spoke’ version of the Maggi (Am Econ Rev 89(1):190–213, 1999) model of trade negotiations to shows that the combination of the WTO single-undertaking and consensus decision-making principles with an expanded and more diverse membership can render multilateralism less desirable for hub countries than bilateralism. It is argued that these principles give spoke countries de facto veto power meaning that their threat point during WTO negotiations is a reversion to PTA negotiations between all parties. Accordingly, spoke countries with relatively less to gain from the WTO can use their veto power to extract gains from those that would benefit substantially. If an expanding WTO membership has increased the number of such countries, then the benefits of multilateralism versus regionalism from the perspective of hub counties may have been diminished to such an extent that they are no longer willing to wait for the conclusion of the Doha round before engaging in PTA negotiations.     

The Role of Ownership in Determining the Rural Economic Benefits of On‐shore Wind Farms

The development of the wind energy sector is often promoted as a means of supporting rural economies. This paper focuses on how the ownership structure of on‐shore wind power plants (external, farmer or community) affects the size and distribution of impacts within the rural part of a region. Empirical analysis is based on a regional computable general equilibrium model of North East Scotland with the results compared to those generated from a standard social accounting matrix multiplier analysis. With no local ownership, while rural GDP increases, there is almost no effect on household incomes due to the limited direct linkages of the on‐shore wind sector. Local ownership increases the household income benefits but there are still limited positive spill‐over effects on the wider economy unless factor income is re‐invested in local capital. With re‐investment, farm household ownership gives rise to the largest increase in total household income but community ownership gives rise to the largest increase in rural (non‐farm) household incomes and welfare. The results contribute to the on‐going debate about the opportunity cost of external asset ownership in rural areas.     

Net capital outflows and the viability of family farms

Abstract

The importance of the family farm in EC agriculture is undisputed. This paper focuses upon the potential impact on family farms of capital outflows which arise from the Napoleonic Code inheritance system which is in place in many continental countries. This system implies that the transfer of ownership of the farm between generations is typically associated with a requirement for the successor to buy out the non‐succeeding heirs. The potential effects of these capital outflows on the family farm's current consumption and ability to pass on a viable unit to the next generation is illustrated using two versions of a life cycle simulation model using two definitions of what constitutes future family farm viability. The numerical results give some indication of the extra burden imposed by the Napoleonic Code inheritance system relative to primogeniture.     

The impact of information and communication technology on international trade in fruit and vegetables in APEC

The global food marketing network is being constantly reshaped, providing opportunities and challenges for information and communication technology (ICT) to develop and improve international trade in food products. A gravity model of international trade is employed to see if ICT positively affects bilateral international trade in fruit and vegetables between member Asia‐Pacific Economic Cooperation (APEC) economies. We examine if the use of the Internet, mobile telephones, and fixed telephone lines determine the value of bilateral trade. Empirical results for the importance of ICT differ markedly between importing activities and exporting activities in the international value chain of fruit and vegetables in APEC countries. Changes in ICT levels in the import sector of the value chain have no effect on international trade in fruit and vegetables. However, in the export sector, growth in some ICT products has significant positive effects on trade in fruit and vegetables between APEC countries. Surprisingly, the strongest impact was discerned for the traditional form of ICT, fixed telephone lines, but this impact probably reflects the fact that fixed telephone lines are a proxy variable for the general level of infrastructure development. Of the two digital ICTs, mobile telephony and the Internet, only the Internet had a significant impact on trade levels. The further development of the Internet and its diffusion should make exporters in APEC countries more competitive in the fruit and vegetables value chain, and boost their trade values in these products.
