Characteristics of Private‐Sector Tractor Service Provisions: Insights from Nigeria

Agricultural mechanization has been integral to agricultural transformation during periods of development. Mechanization‐service provisions can be constrained by economies of scale, seasonality, limited mobility, or heterogeneous inputs quality. However, information has been scarce regarding how the private sector has overcome these constraints especially in countries like Nigeria that are at low agricultural development stages. We present the results of a small survey of tractor owner‐operators conducted in Nigeria. We find that existing private‐sector tractor‐hiring services in Nigeria are indeed constrained. However, we also find heterogeneity among these owner‐operators. In particular, those who buy tractors from private markets or from private individuals are more efficient than those who receive tractors through government programs, providing services to a greater area at lower costs, including during off‐peak seasons, sometimes selecting machinery types according to soil types. We conclude with a discussion of some policy implications.     

Incomplete property rights, exposure to markets and the provision of environmental services in China

This paper uses data from a 2003 rural survey to examine the determinants of household provision of environmental services under China's Sloping Land Conversion Program (SLCP), the largest payments for environmental services program in the developing world. The paper examines the determinants of plot-level survival rates of program-planted trees and grasses. It finds that household rights over retired land as well as autonomy in program decision-making (which we argue on the basis of supportive evidence are plausibly exogenous to post-retirement outcomes) have important and potentially countervailing impacts on the provision of environmental services targeted by the program. Households permitted to select what to plant obtain better program outcomes, but do not make the choices that the government would like them to, while those permitted to decide what land to retire perform worse. The analysis also finds that households more vested and experienced in agriculture and with less exposure to off-farm labor markets fare better in managing their planted trees. Significant learning-by-doing effects are also evident, suggesting that greater technical support to farmers could improve outcomes and lower program costs.     

THE LONG‐TERM ECONOMIC CONSEQUENCES OF AGRICULTURAL MARKETING LEGISLATION IN SOUTH AFRICA

The marketing of most agricultural products in South Africa was subject to intervention by statutory bodies over a period of some 60 years. At the time of the promulgation of the first legislation there was a vigorous debate on the predicted economic effects; in 1983 one of the architects of these instruments published a justification in these pages, followed in 2000 by a “post‐mortem,” which confirmed most of the negative predictions that had been made. The purpose in this article is to revisit this debate and to provide a first assessment of the long‐term impacts of the legislation.     

The Impact of Farmland Transfers on Agricultural Investment in China: A Perspective of Transaction Cost Economics

There is growing concern that farmland transfers lead to less agricultural investment, which may adversely affect agricultural productivity growth in China. Prior research has primarily focused on the differences between owned cultivated land and rented plots, but little is known about how farmland transfers between relatives, which are popular in rural China, specifically affect agricultural investment. In this paper, we present a conceptual framework of transaction cost economics to compare different contracting strategies in China's farmland rental markets. As farmland rental markets in China are immature, land transfer between relatives establishes bilateral governance, which has the advantage of addressing the opportunistic activities of both parties and can ultimately increase investment by tenants. Based on data from two waves of household surveys, we empirically examine the impact of bilateral governance on the application of organic fertilizer, an indicator for agricultural investment. Our findings show that apart from economic factors, kinship is important to the functioning of farmland rental markets in rural areas.     

Food Security and Agricultural Changes in the Course of China＇s Urbanization

China's small farmers face increasing challenges because of land and water resource constraints and the effects of climate change. With the strengthened agricultural stimulus policies, poverty reduction and social protection programs, as well as the expanding international food trade, up to now China has achieved food security through small farm agriculture. During intensive economic restructuring, smallholders still coexist with large‐sized farms and industrialized agricultural businesses, but are in a vulnerable position in market transactions. Oriented to 2050, China's agricultural development and food security policies should work to improve domestic market structure, to further release international trade control and to empower smallholders.     

Trade, technology spillovers, and food production in China

Trade, Technology Spillovers, and Food Production in China. — This paper studies technology spillovers between China and other countries, international trade in inputs being the prime carrier of knowledge in agricultural production. Human capital characteristics and structural characteristics of the agricultural production sys-tems determine the local usability of foreign knowledge for Chinese farmers. The authors utilize a multi-region applied general equilibrium model to analyze Chinese opportunities to benefit from foreign technology improvements in grain production. It is shown that possible negative welfare effects of unilateral trade liberalization of China against North American imports of agricultural inputs may be more than compensated by productivity gains if technology spillovers are included.     

The Invisible Hand of Rain in Spending: Effect of Rainfall‐Driven Agricultural Income on Per Capita Expenditure in Ghana

This paper uses a nationally representative household pseudo‐panel dataset for Ghana, a rain‐fed agriculture economy, to investigate whether there is a positive relationship between rainfall‐driven agricultural income and household per capita expenditure. By using the Two Stage Least Squares Instrumental Variable (2SLS‐IV) estimator, it is found that a fall in rainfall‐driven agricultural income leads to a decrease in per capita expenditure. The results show that the gender and the locality of the household head matter in the response of per capita expenditures to rainfall‐driven agricultural income. Female‐headed and rural households are more vulnerable to rainfall‐driven agricultural income changes. The expenditure disaggregation indicates that female‐headed households significantly reduce per capita non‐food expenditure in times of rainfall‐induced agricultural income decrease whilst the response of male‐headed households focuses more on reducing per capita food and remittance expenditures.     

What are the Determinants of Large‐scale Farming in China?

The Chinese Government has increased its focus on expanding farm scale to promote agricultural development since 2010. A series of favorable polices has been adopted to support large‐scale farming. Using a multivariate probit model and 2015 and 2016 rural household survey data, the present paper examines the factors that influence small farmers' decision to become large‐scale farmers. The empirical regression results suggest that the decision to become a large‐scale farmer is significantly influenced by household human capital, cooperative membership, marketing channels, land‐transfer contracts and government policies. However, the influence of these factors differs with respect to becoming large‐scale grain and non‐grain farmers. These results imply that policy tools should target these factors and the appropriate group of small‐scale farmers. Generally, both central and local governments should promote large‐scale farming by enhancing rural households' human capital, improving marketing channels and providing agricultural social services, as well as encouraging returning migrant workers to engage in large‐scale farming.     

COLONIALISM AND LONG‐RUN GROWTH IN AUSTRALIA: AN EXAMINATION OF INSTITUTIONAL CHANGE IN VICTORIA'S WATER SECTOR DURING THE NINETEENTH CENTURY

Institutional change in water rights in the nineteenth century Australian colony of Victoria raised institutional efficiency, which contributed to long‐run economic growth. High‐quality human capital and the extension of voting rights (franchise) were crucial for efficient institutional change in the water sector. Quality human capital (literacy) appeared to increase the rural population's awareness of the economic impact of the existing structure of water rights that may have constrained growth in the agricultural sector and reduced investment incentives. Extension of the franchise allowed the rural population to exert political pressure for enactment of change in water rights, which resulted in efficiency‐enhancing policies and efficient institutions. The findings show these two factors were more important than Victoria's British colonial heritage in determining whether growth‐enhancing institutional change took place.     

EXPLOITING MARINE WILDLIFE IN QUEENSLAND: THE COMMERCIAL DUGONG AND MARINE TURTLE FISHERIES, 1847–1969

The historical exploitation of marine resources in Queensland has only been partially documented. In particular, the history of the commercial fishing of dugongs and marine turtles has received comparatively little scholarly attention. Since European settlement in Queensland, various human activities have exploited these resources. We present documentary and oral history evidence of the scale of those industries. Based on extensive archival and oral history research, we argue that diverse fishing practices occurred and that the sustained exploitation of dugongs, green turtles, and hawksbill turtles led to observable declines in the numbers of these animals – now species of conservation concern.     

Productivity growth, technological progress, and efficiency change in chinese agriculture after rural economic reforms: A DEA approach

This study applies a data envelopment analysis (DEA) approach to analyze total factor productivity, technology, and efficiency changes in Chinese agricultural production from 1984 to 1993. Twenty-nine provinces in China were classified into advanced-technology and low-technology categories. The Malmquist (1953) productivity measures were decomposed into two components: technical change index and efficiency change index. The results show that total factor productivity has risen in most provinces for both technology categories during the 1984–1993 period. Technical progress was mostly attributed to Chinese agricultural productivity growth after the rural economic reforms. The deterioration in technical efficiency in many provinces indicates China has great potential to increase productivity through improved technical efficiency. Enhancing rural education and research and development (R&D) in agriculture may also help farmers to improve technical efficiency and productivity in agricultural production.     

EQUILIBRIUM FARM GATE PRICE IN THE CASE OF TWO SUCCESSIVE MARKETS WITH FIXED SUPPLY

This study aims to describe the evolution of the organisational structure of raw agricultural product markets in West African countries (the supply may be regarded as fixed) using microeconomic models to assess the evolution of the farm gate price; and focusing on the impact of the vertical integration of some firms on the producer price. This paper shows that the evolution of the commercial organisational structure of agricultural products has led to a gradual improvement in the producer price. It also shows that whatever the degree of vertical integration on these markets, it has a positive impact on the farm gate price. However, even if vertical integration also improves the price of agricultural input on the intermediary market, the intermediary firms undergo a deteriorating situation.     

Effects of Pastoralism and Rabbits on the Economy and Culture of the Diyari People of North‐Eastern South Australia

The contraction of Aboriginal people from South Australian deserts is associated with European pastoral expansion. Confined to areas near water, livestock damaged vegetation locally, but introduced rabbits, not reliant on drinking water, spread well beyond pastoral settlement. Thus, rabbits caused almost universal desertification and were an equal factor in disrupting the former food web that sustained Aboriginal people. Within 30 years of the rabbits' arrival, important totemic animals like rabbit bandicoots had disappeared, leaving the people not only short of traditional game but also culturally bereft. A comparative economic approach to Aboriginal totemism explores changes in both ecological and cultural contexts.     

IS THERE POLICY SPACE TO PROTECT SOUTH AFRICAN AGRICULTURE?

The aim of this paper is to assess the amount of “policy space” available to increase tariff protection in South African agriculture. To this end, formal definitions for agricultural produce, actual import data, applied tariff data and bound tariff rates and tariff quota information were used to investigate the extent to which it is possible and feasible to increase tariffs. The analysis shows that in general the policy space available to South African agriculture is limited because of, among others, WTO binding and treaty obligations under the EU and SADC agreements. Furthermore, it does not make policy sense to increase protection on most other products.     

BLASTING OUT: EXPLOSIVES PRACTICES IN QUEENSLAND METALLIFEROUS MINES, 1870–1920

The use of explosives in mines in the late nineteenth and early twentieth centuries was notoriously unsafe. In Queensland's underground metalliferous mines, explosive practices could be dangerous not only because of the attitudes of miners and managers, but because of problems inherent to the technology, conditions underground, economic fluctuations, and the persistence of outmoded practices. Some limited specialisation of labour occurred in the interests of safety, and although newer technology had the potential to deskill the work of miners, these developments were quite dissimilar to the highly specialised work practices that were adopted for large-scale mining in the United States during the same period.     

The Role of Agriculture on the Recent Brazilian Economic Growth: How Agriculture Competes for Resources

Drawing upon the Global Trade Analysis Project (GTAP) database, and other time series data, we construct a multi‐sector Ramsey model that shows the transition growth of the Brazilian agricultural sector and its effects on growth of the industrial and service sector of the economy, with particular emphasis given to the years 1994–2010. Our results capture the importance of the agriculture's capital intensity and the sector's factor productivity on the sector's growth, the substitution of capital for labor in agriculture, and the sustaining of agriculture's share in Brazilian GDP. These features are rather unique among emerging economies, most of which have experienced a transition out of agriculture and growth in nonfarm production relative to agriculture.     

Ethnic Diversity,Political Stability and Productive Efficiency: Empirical Evidence from the African Countries

While ethnic diversity has been shown to produce numerous negative effects on the economic performance due to disagreement on the production of the public good, nepotism in making employment decisions, increased corruption and rent‐seeking behaviour, its positive effects appear to have received much less attention. We hypothesise and test several explanations why higher levels of ethnic diversity may be associated with better socio‐economic outcomes. We find that productive efficiency will be higher in the societies where ethnicities can benefit from the complementarity of skills. Incentives to engage in an ethnic conflict will be lower and the extent of political stability higher in those countries where the opportunity costs of ethnic conflict are more substantial. We also find some evidence in support of the political aspirations hypothesis that attributes the negative effects of ethnic diversity to the strife by ethnic groups for more political influence.     

THE FOOD SECURITY PROBLEM IN ETHIOPIA – A SUPPLY SIDE ANALYSIS

Since 1961 Ethiopia has been ruled by a Monarchy, a Marxist military dictatorship, and presently by a coalition of political parties that came to power in 1991after a protracted civil war. These three governments have pursued different ideologies in formulating policies to guide agricultural development. However, to date Ethiopia remains food insecure. Ethiopian agriculture is dominated by peasant farmers and 85 per cent of the population is rural. Rural poverty and, hence, food insecurity is intricately related to insufficient land and a lack of long‐term tenure security. The aggregate country level food security was assessed using various indicators for the periods of the three governments. The growth rates and the variability in the indicators suggest that Ethiopia is suffering from both chronic and transitory food insecurity.     

Are China's Farms Growing?

China's agricultural sector faces challenges because most farms are still small scale. China's policy is to encourage the consolidation of farms and promote farms that are larger in scale. A question that arises is: Are China's farms growing? The goal of the present paper is to determine whether large farms in China have emerged or if farms remain small. To meet this goal, we systematically document the trends in the operational sizes of China's farms and measure the determinants of changes in farm size. Using a nationally representative dataset, the study shows that in 2013 China's farming sector was still mostly characterized by small‐scale farms. However, at the same time, there is an emerging class of middle‐sized and larger‐sized farms. Most large farms are being run by households but there is a set of large farms that are company/cooperative‐run. Today, farmers on larger farms are younger and better educated than the average farmer.
