Paradise postponed: dilemmas facing shop stewards in the new South Africa—accommodation orresistance?

The growth of the shop stewards movement in South Africa prior to majority rule represented a challenge to the institutionalised managerial prerogative and cemented the position of black trade unions in the workplace, posing a threat to both Apartheid’s cheap labour system and also to the political control of the Apartheid regime. With the advent of majority rule in 1994, shop stewards are now expected to comply with, and co-operate in, the implementation of workplace changes which they would have traditionally opposed. This, plus the move towards Japanese-style ‘lean’ work practices, is creating farreaching challenges for the ‘New’ South African shop steward movement.     

The Economics of Apartheid Politics

Apartheid in South Africa is too often discussed in emotional or nationalistic terms. Professor Duncan Reekie, a Scottish economist now teaching at the University of the Witwatersrand in Johannesburg, analyses the economic aspects of the political forces working with and against eventual liberalisation.     

Financial bootstrapping and venture development in the software industry

Access to finance has been identified as a significant constraint on the development of technology-based businesses. Although important, institutional venture capital and business angel finance are used by only a small proportion of new and growing ventures. The role of bootstrapping – defined here as access to resources not owned or controlled by the entrepreneur – has been largely overlooked in studies of small firm financing. This paper redresses this omission by analysing the role and importance of bootstrapping in product development and business development in the independently-owned software industry. Results from two regions of the UK – Northern Ireland and South East England – are compared with equivalent data from the USA (Massachusetts). Overall, bootstrapping techniques are less extensively used in the Northern Ireland industry than in South East England, and in both regions bootstrapping is less common than in Massachusetts. This may account for the smaller employment size, growth profile and stronger service/consulting orientation of these firms. Moreover, there appear to be considerable variations in the use of bootstrapping. Larger firms tend to make more use of bootstrapping for product development, and consider it more important than do smaller firms, who more highly value business development-related bootstrapping. Small firms are also more likely to use and value cost-reducing bootstrapping techniques, whereas larger firms make more use of the exploitation of value-chain based relationships.     

Investment-specific technical progress,capital obsolescence and job creation

This paper shows that faster disembodied technological progress – if it is investment-specific – might reduce job creation because the obsolescence cost of capital increases, which reduces the net return of a job. This effect could be called the obsolescence effect. It is also shown that the increase in the rate of decline of the U.S. relative price of investment – which can be used as a proxy for the rate of investment-specific technical progress – may have increased the obsolescence costs of capital, which might account for the observed fall in U.S. vacancy–unemployment ratios and job finding rates after the mid-seventies.     

Will We Ever Meet Again? The Relationship between Inter-Firm Managerial Migration and the Circulation of Client Ties

A large body of research shows that the migration of managers from one professional service firm to another weakens the old employer’s relationship with its clients, because migrating managers remove their relationship-specific knowledge and expertise – i.e., human and social capital – from their old employers, redeploying it to their new employers. This study extends this research by introducing a bi-directional perspective of social capital in which both firms and managers may exploit these relationship-specific resources. We use theory on social capital to build arguments about how one form of manager mobility, manager migration between two service providers in a single market, can both lead and lag the movement of client ties between those providers, and signaling theory to hypothesize the conditions under which this is likely to occur. Analyses using longitudinal data on New York City advertising agencies generally support our arguments. Our findings contribute to theory and research on manager migration, social capital, and signaling, and raise new questions for how the portability of relationship-specific social capital shapes markets.     

Tax-benefit systems and differences in aggregate labour force participation: Comparative evidence from the Czech Republic and Hungary

This paper investigates the extent to which cross-country differences in aggregate participation rates can be explained by differences in tax-benefit systems. We take the example of two countries, the Czech Republic and Hungary, which – despite a lot of similarities – differ markedly in labour force participation rates. Using comparable individual-level labour supply estimates, we simulate how the aggregate participation rate would change in one country if the other country’s tax and social welfare system were adopted. The estimation results for the two countries are quite similar, suggesting that individual preferences are essentially identical in the two countries. The simulation results show that about one-third of the difference in the participation rates of the 15–74 year-old population and more than two-thirds of the participation of the prime-age population can be explained by differences in the tax-benefit systems.     

The Hicksian trade cycle with floor and ceiling dependent on capital stock

This article reconsiders the Hicksian multiplier – accelerator model with ‘floor’ and ‘ceiling’. The new thrust is that these constraints are tied to the actual stock of capital, the floor to the depreciation on this stock, the ceiling to capital as a limiting production factor according to the fixed proportions technology that also underlies the principle of acceleration. For capital formation just the Hicksian investment theory is used. The result is one unified model creating economic growth and growth rate cycles.     

Factor Utilization and Adjusted Productivity Estimates for the UK*

This paper derives series for capital utilization, labour effort and total factor productivity (TFP) for the UK from a general equilibrium model with variable utilization and labour adjustment costs. Capital utilization tracks survey‐based measures closely, but persistent movements in total hours worked mean our labour effort series is not as highly correlated with its comparators. Our estimated TFP series is less cyclical than the traditional Solow residual, although a weighted average of capital utilization and labour effort – aggregate factor utilization – and the Solow residual are not closely related.     

Supply chain finance schemes in the procurement of agricultural products

Product, information, and finance flows are all interrelated within the modern supply chain; thus, it is now more than ever of paramount importance for practitioners to integrate procurement and financial decisions. This challenge is exemplified in many agricultural supply chains, where operational risks are significant and access to capital differs sharply across firms. We study three management tactics that some large food/beverage manufacturers – situated downstream in these chains – have used to meet the challenge: ordinary fixed price contracts (or soft tolling) with direct suppliers, hard tolling and contract farming where the manufacturer intervenes upstream, providing capital, and coordinating procurement decisions. We place these upstream intervention schemes in the theoretical context of supply chain finance (SCF) and model their application to a three-echelon agricultural supply chain. We perform a numerical study in order to understand how the structure of capital constraints in the chain may influence the manufacturer's choice of SCF scheme. The numerical study is based on a business case that reflects the barley–malt supply chain of Heineken N.V. Despite greater coordination opportunities, we show that upstream intervention is not necessarily preferable for the manufacturer. Nevertheless, the preferred SCF scheme can be inferred on the basis of relatively simple characterization of the capital constraints in the supply chain.     

The impact of voluntary corporate disclosures on the ex-ante cost of capital for Swiss firms

The relationship between disclosure quality and cost of equity capital is an important topic in today's economy. In general, economic theory and anecdotal evidence suggest a negative association. Empirical work on this link, however, is confronted with major methodological drawbacks – neither disclosure level nor cost of capital can be observed directly – and has documented somewhat confounding results so far. Adopting a finite horizon version of the residual income model, I provide evidence on the nature of the above relationship and try to quantify the effect of a firm's voluntary disclosure policy on its implied cost of capital. Switzerland seems especially suited for an analysis of this kind given that Swiss firms have considerable reporting discretion and the mandated level of disclosure is low. For a cross-sectional sample of seventy-three non-financial companies I show a negative and highly significant association between the two variables. The magnitude is such that the most forthcoming firms enjoy about a 1.8 to 2.4% cost advantage over the least forthcoming firms. The findings persist even after controlling for other potentially influential variables, e.g. risk characteristics and firm size. Furthermore, adjusting for self-selection bias – a major concern in disclosure studies – the marginal effect remains of the same direction and even increases in magnitude, although at lower levels of statistical significance. One reason for the strong relationship might be found in differing institutional factors between the US and Swiss capital markets.     

The precious bane

Are natural resources harmful to growth? We address this question using a two-sector, endogenous growth model in which human capital is the engine of growth. By increasing the rewards to unskilled labor, natural resources make schooling more expensive. As long as the intertemporal elasticity of consumption substitution is not too high, this slows down human capital accumulation and growth. The presence of production spillovers from human capital, however, implies that a planner could react to a resource boom by increasing human capital accumulation even though the decentralized solution yields the exact opposite. The paper also shows that as the production complementarity between natural resources and unskilled labor declines, the growth effects of natural resources become increasingly sensitive to whether or not there is free trade in goods. The empirical evidence lends support to the main channel – natural resources to human capital to growth – that is suggested in the paper.     

Social capital and entrepreneurial process

The paper examines the relationship between social capital and entrepreneurial engagement of individuals in 35 nations from Europe and Asia. To the best of our knowledge, this is the first empirical research that attempts to investigate the influence of three-dimensional social capital concept – trust, networks and norms – on three stages of entrepreneurial process – preference, trial and success – using such large and comprehensive cross-sectional micro data. In general, we find that all three dimensions of social capital matter in the entrepreneurship context, albeit differently. They become beneficial in different ways and at different stages of entrepreneurial involvement. For example, among trust variables, institutional trust in general, and trust in business-oriented and business-supporting actors in particular, exert significant positive effect on entrepreneurial process. Individuals with formal membership in professional associations are more likely to perceive entrepreneurial opportunities, while some close or strong-tie networks might prevent them from progressing in the entrepreneurship ladder. Finally, individual level civic norms appear to be negatively associated with early-stage entrepreneurship, while the success in becoming an entrepreneur is not found to be bound by people’s civic norms.     

Gravity's pull: The identity-related motives and outcomes of hiring stars

Strategic human capital scholarship, alongside a wealth of evidence from the popular press, suggests that star employees can influence an organization's socially constructed identity. However, an overarching conceptual framework that explains these shifts has yet to emerge. In this paper, we draw upon Hatch and Schultz's (2002) theory of identity change to discuss how organizational identity-change related motives – defined as decision makers' interest in spurring changes to socially constructed, internal perceptions of their organization's central and distinctive features – act in concert with considerations of value creation and capture to influence the hiring of different identity-aspirant stars (i.e., stars that embody a desired future organizational identity). Given that stars represent catalysts for identity change that have agency and become part of the social fabric of an organization, we then explain how the mechanisms by which stars' attempts to gain or retain status – coupled with organization members' willingness to emulate their behaviors – can affect internal-oriented organizational identity change. This paper advances consideration of social-psychological factors alongside economic views of stars and offers implications for the literatures on strategic human capital and organizational identity.     

Capital and trade flows in Europe and the impact of enlargement

The Eastern enlargement of the European Union (EU) is likely to give a further boost to trade and capital flows, yet empirical evidence on its possible effects is scarce. This paper uses four different datasets to estimate the determinants of international asset holdings and trade flows. We find in most regressions that EU membership has a significant effect. Based on additional forecasts of the expected flows to 10 transition economies, we conclude that for the EU candidates actual levels are still far below expected values in most cases. Consequently, we anticipate raising capital and trade flows with the approach of EU accession, in particular for the seven EU candidates besides the Czech Republic, Hungary, and Poland.     

Cities in Contemporary Capitalism

This article outlines essential concepts of the political economy approach of urban research and offers critical modifications and clarifications to some of its contentions concerning the functioning of cities as ‘strategic places’ of capital accumulation. The interrelations between contemporary capitalism and urban economic development are discussed at the scale of a transnationally extended urban system. Based on the general context of the global economic downturn, I focus on the role of cities in distinct circuits of capital, the switching of capital flows within the urban system and the different functional roles of cities within the world city network that interconnects cities both in the global North and South. I call into question the established focus of urban economic research on the role of cities as financial and service centres, arguing that cities might redirect their economic development trajectories towards ‘real economy’ activities, in contrast to relying on the disastrous development model of finance‐dominated capitalism.     

Learning in owner-managed small firms: Mediating artefacts and strategic space

The authors focus on the way in which owner-managers in smaller firms improve their businesses through the creation of ‘strategic space’. The term ‘strategic space’ refers to the process by which owner-managers are able to access resources, motivation and capability to review existing practices. The starting point is the owner-manager's human capital and their capacity to engage in critical reflection about their business. We highlight three concepts central to the creation of strategic space, first, social capital, which refers to the network relationships that provide access to a wide range of resources and information. Second, absorptive capacity, which describes the way in which organizational members identify, acquire and utilize knowledge from external sources. Third, mediating artefacts, which represent existing knowledge but also facilitate the translation and transformation of understanding within and between communities of practice. This process is essential to the renewal of knowledge and knowing within firms. The contribution this paper makes is to bring together these elements – human and social capital, absorptive capacity and mediating artefacts – to offer a conceptual model that illustrates the mechanism by which owner-managers create strategic space. This model provides a deeper understanding of the evolution of knowledge in smaller organizations.     

Frontier Technology and Absorptive Capacity: Evidence from OECD Manufacturing Industries*

In this paper, we examine the three facets of technology: its creation, dispersion and absorption. We investigate whether differences in absorptive capacity help to explain cross‐country differences in the level of productivity. We utilize stochastic frontier analysis to investigate two potential sources of this inefficiency – differences in human capital and R&D – for nine industries in 12 Organization for Economic Co‐operation and Development (OECD) countries over the period 1973–91. We find that inefficiency in production does indeed exist and it depends upon the level of human capital of the country's workforce. Evidence that the amount of R&D an industry undertakes is also important is less robust.

Foreign capital inflows and poverty linkages in South Asia: Do the forms of capital inflows matter?

The relationship between foreign direct investment and poverty reduction has received modest attention in the empirical literature. However, little is known about the relative significant impact of different forms of capital inflows on poverty reduction. This study attempts to investigate the impact of different forms of capital inflows (foreign direct inflows, portfolio equity and portfolio debt inflows) on poverty reduction in major South Asian economies during the post-reform period. The capital inflows-poverty nexus is explored using panel econometric methods robust to cross-sectional dependence. Our empirical results show that while portfolio equity inflows exert a favorable impact on poverty reduction, foreign direct inflows and debt inflows fail to influence poverty. The panel causality results demonstrate that portfolio equity inflows also support poverty alleviation via stimulating economic growth and trade openness. The findings of our study highlight the importance of considering the differential welfare impacts of different forms of capital inflows while implementing capital account liberalization.     

Emergent dynamics of a macroeconomic agent based model with capital and credit

In this paper we present and discuss a Macroeconomic Agent-Based Model with Capital and Credit (CC-MABM) which builds upon the framework put forward by Delli Gatti et al. (2011). The novelty of this model with respect to the previous framework consists in the introduction of a stylized supply chain where upstream firms – i.e. producers of capital goods (K-firms) – supply a durable and sticky input (capital) to the downstream firms, who produce consumption goods (C-firms) to be sold to households. Both C-firms and K-firms resort to bank loans to satisfy their financing needs. There are two-way feedbacks between firms and markets which yield interesting emerging properties at the macro level. We show that the interaction of upstream and downstream firms and the evolution of their financial conditions – in a nutshell: Capital and Credit – are essential ingredients of a “crisis” i.e. a sizable slump followed by a long recovery.
