Multinational mining enterprises and artisanal small-scale miners: From confrontation to cooperation

In many developing countries, multinational enterprises (MNEs) in mining operate alongside fast-growing communities of informal artisanal, small-scale miners. This has led to direct conflict and competition for mineral resources. This paper introduces the Salience and Institutional Analysis and Design framework as a means to analyze the MNE strategies used to address informal miners across different governance levels in the gold mining sector of Ghana and discusses the implications of these strategies for sustainability. We identify the emergence of a cooperative strategy with informal miners as a sustainable alternative to the political strategy of reliance on the state to protect tenure.     

Are consumers at the base of the pyramid willing to pay for nutritious foods?

Base of the Pyramid (BoP) consumers living in the urban informal settlements of developing countries spend over 60% of their income on food, yet malnutrition and micronutrient deficiency remain widespread among these populations, pointing to the inadequacy of the foods they consume in terms of quality and quantity. In this paper we examine BoP consumers’ willingness to pay (WTP) for nutritious multi-composite porridge flour (improved flour) in the informal settlements of East Africa. The analysis is based on experimental data collected from 600 households in the informal settlements of Kampala, Uganda and Nairobi, Kenya (300 in each country) in 2016. We use Tobit regression models to analyse determinants of WTP for the improved porridge flour. Results show that both Kenyan and Ugandan BoP consumers are willing to pay a premium for the improved porridge flour. In addition, providing nutrition information about the flour, characteristics of household head, economic status of the household, and presence of young children between six and 59 months in the household, influence WTP for the safe and nutritious porridge flour. The paper concludes by providing recommendations for enhancing nutrition among poor consumers in the informal settlements of developing countries.     

基于熵值法的人居环境质量评价研究——以徐州市为例

在分析城市人居环境系统构成的基础上,构建了人居环境质量评价指标体系,利用熵值法对1991-2005年徐州市区的人居环境质量进行了分析与评价。结果表明,1990年代以来,徐州市区人居环境质量有了较大的提升和改善,并据此就徐州市区城市规划、基础设施建设、生态环境建设和保护等方面,提出了优化人居环境的措施和对策。     

非正规部门竞争、政治寻租与新创企业市场创新

市场创新是新创企业生存发展的根本,然而新兴经济体背景下新创企业的市场创新受到多种特定因素的影响。基于制度基础观,利用世界银行中国企业调查数据,实证考察了非正规部门竞争和政治寻租对新创企业市场创新的影响。研究发现,非正规部门竞争和政治寻租均对新创企业的市场创新具有显著的正向影响,但政治寻租未强化非正规部门竞争对企业市场创新的正向影响;非正规竞争导致的对知识产权保护的需求并非是引致新创企业进行政治寻租的主要原因,资金需求和躲避严苛繁琐的政府管制的需要是引诱企业参与政治寻租的主要原因。因此,政策制定者不必过分担忧非正规部门竞争对新创企业的负面影响,而应通过推进企业注册登记便利化和加强知识产权保护逐步消除非正规经济;要通过持续深化市场化改革和简政放权消除企业寻租的动机。

The motives of off-the-books entrepreneurs: necessity- or opportunity-driven?

In recent years, it has become common to represent entrepreneurs as either necessity- or opportunity-driven. Drawing upon face-to-face interviews in England with 70 entrepreneurs trading wholly or partially off-the-books, this paper evaluates critically this dichotomous representation. The finding is that squeezing the motives of off-the-books entrepreneurs into one side or the other of this dichotomy not only over-simplifies their rationales since both necessity and opportunity motives are often involved but also obfuscates how their motives change over time. The outcome is a call to replace this either/or depiction with a richer and more nuanced both/and understanding of off-the-books entrepreneurs that recognises their diverse and dynamic motives.

Informal pay gaps in good and bad times: Evidence from Russia

Informal work is traditionally large in Russia and has further increased in the recent years. We explore the implications of this shift in terms of wage dynamics. Our characterization is based on the estimation of informal pay gaps at the mean and along the wage distribution, relying on the Russian Longitudinal Monitoring Survey for 2003–2017. Our approach comprises three original features: we rely on unconditional quantile effects of informality, we incorporate quantile-specific fixed effects using a tractable approach, and we suggest a treatment of the incidental parameter bias. Over the whole period, informal wage penalties are relatively small and do not suggest heavily segmented labor markets, even at low wage levels. Yet, in the past decade, a substantial negative selection into informal employment and self-employment has taken place, on average and especially at low earnings. Economic downturns and labor market policies have likely contributed to the shakeout of less productive workers in the formal sector, making the low-tier informal sector more of a last resort.     

Do Court Decisions Drive the Federal Trade Commission’s Enforcement Policy on Merger Settlements?

Mergers are generally conglomerate in nature with only minor (if any) horizontal overlaps. Under U.S. law, an enforcement agency may challenge any anticompetitive aspect of the merger and the consequent delay associated with litigation would impose costs on the firm. These costs may give the enforcement agency “leverage” to extract a settlement even when the firm would prevail in court. This paper explores whether the FTC’s decisions to challenge transactions approximate the case law. We find that the representative enforcement regimes of the FTC and the courts are remarkably similar, although the FTC credits efficiencies, while courts consider buyer sophistication as a mitigating factor.     

Strategic interaction between inter vivos gifts and housing acquisition

This paper models the interdependence of parental inter vivos gifts and children’s home purchases when informal care affects decision making. We use data from Japanese households who purchased a detached house in an urban area to test this strategic interaction. Considering both censoring and endogeneity of inter vivos gifts, which are identified by information on formal care, our preferred results demonstrate that inter vivos gifts do not significantly increase the purchase price of housing. Theory suggests that this occurs when informal care tends to be a heavy burden for children. However, subsample analysis of young home buyers indicates that the empirical results are consistent with the literature: children who receive parental gifts tend to purchase a higher-priced dwelling. One potential explanation is that relatively young adult children are less likely to take charge of care obligations, and accordingly, parental gifts are only expected to relax their liquidity constraints. Subsample analysis appears to indicate that the underlying motivation of parental gifts is influenced by the timing of children’s home purchase decisions.     

Local formal interpersonal networks and SMEs internationalisation: Empirical evidence from the UK

This article uses data from the UK Longitudinal Small Business Survey (2015) to empirically test the relationship between local (formal and informal) interpersonal networks and exporting. Our results suggest that local interpersonal networks increase the likelihood of exporting. More importantly, we find that the role of formal interpersonal networks (e.g. accountants) on internationalisation increases as firm size increases, while the link between informal interpersonal networks (e.g. family) and exporting becomes weaker. We argue that larger firms have more complex operations and diverse structures than smaller firms that require the engagement of formal interpersonal networks to help with the internationalisation process.
