Pure joint production and international trade: a note

This paper applies the principles of the neo-Ricardian (or Sraffian)theory of international trade to certain joint production systems.It is shown that, in contrast with single-product systems, (i)there is not always a pattern of international specialisation,which would entail the increase of the real wage rate in botheconomies, and (ii) the ‘law of comparative advantage’has no general validity. Furthermore, not only the existenceof such a pattern of specialisation but also the validity ofthis law depend on the values of the variables of distributionof income. The analysis is wholly based on two of the numericalexamples formulated by Bidard in 1997, and further generalisedin an elementary way only when this is considered necessary.     

Social Capital,Income Diversification and Climate Change Adaptation: Panel Data Evidence from Rural Ethiopia

The choice between specialisation and diversification of income is driven by multiple, interacting factors, such as economies of scale and scope, risk considerations, context, and household characteristics. Using panel data from Ethiopia, we investigate the role of social capital and the covariate risk of climate change and their interaction. We find that households with greater social capital tend to be more specialised, implying that diversification and informal insurance are substitutes in the mitigation of risk. We also find that this effect is significantly weaker in regions more prone to climate change, which is consistent with the average farmer being aware that informal insurance is not an effective protection against risks that affect the entire social network. We use instrumental variable random effects estimation to account for the plausible endogeneity of social capital and we also establish that our results do not depend on the poorest and most constrained individuals in our sample.     

Examining rural income and employment in Bangladesh: A case of structural changes in the rural nonfarm sector in a developing country

This study uncovers some important stylised facts about the structural changes in the rural nonfarm (RNF) economy in Bangladesh for the period 2000–2016 and identifies some broad determinants. Our work uses household-level, secondary sources such as Household Income and Expenditure Survey, Labour Force Survey and Bangladesh Integrated Household Survey. We find that the positive relationship between landownership and rural income has become weaker in recent years, indicating the increasing role of nonland inputs in generating rural income. The share of RNF income in total rural income has increased substantially over the years. The increase in nonfarm income is largely driven by the nonfarm wage income of the richer households, indicating adverse distributional consequences. There are also indications for specialisation in nonfarm activities—the share of income from the ‘mixed’ sources of farm and nonfarm has decreased, and the ‘only nonfarm’ source has increased. Households tend to move away from agriculture and specialise in RNF occupations as the education level increases. Our results offer important insights into rural development strategies and contribute to the broader questions of the development discourse on the structural changes in developing countries.     

The growing dependence of Britain on trade during the Industrial Revolution

Many previous studies of the role of trade during the British Industrial Revolution have found little or no role for trade in explaining British living standards or growth rates. We construct a three-region model of the world in which Britain trades with North America and the Rest of the World, and calibrate the model to data from the 1760s and 1850s. We find that while trade had only a small impact on British welfare in the 1760s, it had a very large impact in the 1850s. This contrast is robust to a large range of parameter perturbations. Biased technological change and population growth were key in explaining Britain's growing dependence on trade during the Industrial Revolution.     

Trade and Specialisation in Pollution Intensive Industries: North–South Evidence

Abstract

The pollution haven hypothesis (PHH) and the capital-labour hypothesis (KLH) state that the relative level of a country's environmental regulations and capital and labour endowments determines its comparative advantage respectively. Since these hypotheses lead to conflicting predictions as to whether the North or the South will specialise in pollution-intensive production, this paper examines whether changes in trade and specialisation patterns allow us to distinguish between pollution haven and factor endowment effects. We employ a methodology that enables us to present North-South trade patterns over time and to identify those periods when trade patterns were consistent with either the PHH and/or the KLH as a foundation for undertaking more detailed econometric studies.     

产业专业化、职能专业化与城市经济增长——基于中国地级单位面板数据的研究

本文利用2003—2008年中国284个地级单位面板数据,对中国城市产业专业化和职能专业化特征进行了分析,并将职能专业化指标引入动态外部性(MAR溢出、Jacobs溢出)与城市经济增长的分析框架,考察两类专业化对知识溢出进而对城市经济的影响。研究结果表明:中国城市产业专业化和职能专业化水平均较低,但表现出不断提高的趋势;在全国样本范围内,两类专业化水平与城市经济增长均呈现出显著的非线性关系,结合中国城市发展情况来看,更倾向于支持MAR溢出;分地区分规模城市中产业专业化和职能专业化引起的MAR溢出重要性各不相同。基于回归分析的结果,本文还讨论了各类城市的最优专业化水平。     

The strange case of the Matthew effect and beauty contests: Research evaluation and specialisation in Italian universities

The paper aims to determine whether the distribution of funds that prizes the best-performing institutions relatively more has the effect of replicating the Matthew effect within them in terms of personnel policies and allocating proportionally more resources to the best departments to strengthen their output considering the prospect of future assessments. Data from the Italian public university system between 2011 and 2016 as well as the outcomes of the national evaluation of research produced between 2004 and 2010 and between 2011 and 2014 in 14 disciplinary research areas are used. The empirical evidence shows that Italian universities have tended to increase their specialisation in the research areas in which they ranked below or slightly above the national mean, revealing that they chose to try to strengthen the weak sectors through both promotions and new recruitments. The results suggest the existence of a dual policy. When the Ministry of Education, University and Research tries to foster a Matthew effect mechanism, allocating more resources to the best-performing universities, the latter seem to opt to implement a beauty contest strategy to make their weak areas converge towards the national mean. When considering the effects of the recruiting strategies following the national evaluation of research, the results indicate the existence of some Matthew effects, showing that increasing specialisation is more fruitful for the best than for the worst universities.     

The innovation–trade nexus: Italy in historical perspective (1861–1939)

This work investigates the relationship between trade and technological specialisation in Italy, during the long time span ranging from Unification to the eve of the Second World War. To do this, new series of Italy’s indices of specialisation in trade and technology are calculated based on official data. Empirical analysis, based on Spearman rank correlation coefficients and fixed-effects regression, shows the emergence of a positive relationship between specialisation in technology and specialisation in trade after the start of the country’s modern economic growth, around the turn of the twentieth century. This, however, was uniquely driven by a negative relationship between technological specialisation and import shares, while no significant relationship between the former and export shares emerges. Furthermore, this finding excludes the most important sector, leading Italian industrialisation, that is, textiles, the outstanding performance of which can be seen as largely determined by its being particularly suited to the country’s factor endowment.     

Empirical investigation of securitisation drivers: the case of Italian banks

This paper explores the determinants of securitisation by Italian banks over the period 1999–2006, investigating the funding, specialisation, and regulatory capital arbitrage hypotheses. According to our evidence, when we consider all securitisation types together, Italian banks seem to have securitised out of funding motives, to diversify and optimise their available funding channels. When we separately consider securitisations backed by residential mortgages and those backed by non-performing loans, we find that the main factors affecting the former type of securitisation are the need for funding and capital arbitrage motivation, whereas the latter appear to have been affected to a lesser extent by a need for funding and to have also been slightly conditioned by a desire to specialise.

ABSTRACT

Reduced transport costs and income growth in industrialising European countries changed the market conditions for European farmers in the late nineteenth century. Grain prices fell while dairy prices rose. It has been claimed that these price changes hit large grain farmers with vested interests in grain trade particularly hard, while owner-occupiers and smallholders fared better and with help of developing cooperative associations, came out as successful commercial agriculturalists by switching to intensive branches, foremost dairying. Recent research on the Danish case, shows, however, that change was initiated on large elite estates with long-term dairy traditions. The literature on the Swedish case indicates, that larger farms switched to intensified fodder production quicker than smaller farms did, while in the early twentieth century smaller farms played an un-proportionally large role on the dairy market. Using individual farm data from two East-central Swedish parishes in 1878/80, 1895/96 and 1910/11, it is shown, that larger farms tended to modernise crop rotations and switch towards dairy production earlier than small farms did. Smaller farms caught up, and by 1910 their land use was about as strongly adapted to commercial dairy production as larger farms’ land use was.
