Concentric circles of limits to the rate of accumulation: an interpretation of Joan Robinson's theory of economic dynamics

In addition to her well-known contributions to the theory of capital, Joan Robinson provided, in her Accumulation of Capital and Essays in the Theory of Economic Growth, a theory about the determinants of the rate of growth. The growth rate was limited by entrepreneurs' animal spirits. Within that constraint, growth might be further limited by the inflation barrier, which could occur either because of a floor to real wages or because of full employment. This paper provides a series of simple dynamic models that illustrate these situations, drawing attention to this neglected aspect of her work and making it easier to compare her work with the monetary growth models produced by her neoclassical contemporaries.     

Information asymmetries and technological innovation in large engineering construction projects

Research on technological innovation shows that information asymmetries between suppliers and buyers constitute a major barrier to the successful introduction of new products. Most of this research, however, puts the burden of overcoming these asymmetries on producers of new products. In the case of large engineering construction projects innovation is often the result of joint problem solving by owners, prime contractors, consultants, and equipment suppliers. In this paper we examine the relationship between innovativeness of large engineering construction projects and internal owner capabilities, degree of control over project, and dependence on external organizations, We use data on power plant construction projects to test hypotheses derived from agency and organization theories of innovation. Our results indicate that organization theories of innovation are on the whole better predictors of the impact on innovativeness of owner's capabilities and relationship to external organizations.     

Foreign Acquisitions,Domestic Multinationals,and R&D

Our aim in this paper is to evaluate the causal effect of foreign acquisition on research and development (R&D) intensity in targeted domestic firms. We are able to distinguish domestic multinational enterprises (MNEs) and non‐MNEs, which allows us to investigate the fear that the change in ownership of domestic MNEs to foreign MNEs leads to a reduction in R&D activity in the country. Overall, our results give no support to the fears that foreign acquisition of domestic firms leads to a relocation of R&D activity in Swedish MNEs. Rather, in this paper, we find robust evidence that foreign acquisitions lead to increasing R&D intensity in acquired domestic MNEs and non‐MNEs.     

Employment effects of foreign acquisition

This paper investigates the employment effects of foreign acquisitions in acquired firms in Swedish manufacturing during the 1990s; a period characterized by a dramatic increase in foreign ownership. We find some evidence of positive employment effects in acquired firms and it seems that the employment of skilled labor increases more than that of less-skilled labor. Our results indicate that the positive employment effects are more pronounced in acquired non-MNEs than in Swedish MNEs. Furthermore, we observe shifts in skill intensities toward higher shares of skilled labor in non-MNEs taken over by foreign MNEs, but not in acquired Swedish MNEs.     

The price of fear: Estimating the financial cost of bullying and harassment to the NHS in England

Using a spectrum of measures, this paper estimates some of the financial costs of bullying and harassment to the NHS in England. By means of specific impacts resulting from bullying and harassment to staff health, sickness absence costs to the employer, employee turnover, diminished productivity, sickness presenteeism, compensation, litigation and industrial relations costs, we conservatively estimate bullying and harassment to cost the taxpayer £2.281 billion per annum.     

The performance of hedge funds and mutual funds in emerging markets

Use of short selling and derivatives is limited in most emerging markets because such instruments are not as readily available as they are in developed capital markets. These limitations raise questions about the value added provided by hedge funds, especially compared to traditional mutual funds active in these markets. We use five existing performance measurement models plus a new asset-style factor model to identify the return sources and the alpha generated by both types of funds. We analyze subperiods, different market environments, and structural breaks. Our results indicate that some hedge funds generate significant positive alpha, whereas most mutual funds do not outperform traditional benchmarks. We find that hedge funds are more active in shifting their asset allocation. The higher degree of freedom that hedge funds enjoy in their investment style might thus be one explanation for the differences in performance.     

Information Asymmetries and Risk Management in Healthcare Markets: The U.S. Affordable Care Act in Retrospect

This article critically examines the pertinent issues in ex ante and ex post moral hazard in healthcare markets, with the U.S. Affordable Care Act (ACA) as its focal point of inquiry. First, it compares the various types of information asymmetries resulting from the production, allocation, and utilization of health insurance. Second, it reviews the literature on adverse selection, moral hazard, and risk mitigation against which salient ACA reforms are analyzed. In contrasting conventional moral hazard from an alternative theory of welfare maximization, it suggests that healthcare (over)utilization cannot necessarily be considered wasteful, even if it ends up costing insurers more on a short-term basis. Costs and savings attributable to healthcare spending under the ACA will vary between the consumer, insurer, and regulator-subsidizer. Despite the ambiguities surrounding definitions of “health,” the challenge of containing inefficient moral hazard, and encouraging its desirable counterpart, lies in the tradeoffs that arise between consumer access to affordable and quality healthcare and the market competitiveness of health insurers. The new Trump administration will have to address these tradeoffs in repealing and replacing the ACA, particularly in light of escalating insurance premiums and deductibles, narrower provider networks, and technical implementation issues.     

Big Players in Slovenia

The subjectivism of Austrian economics helps to explain the statistical fact of long memory in asset prices. The theory of Big Players is an Austrian approach to understanding the effects of discretionary policymaking in markets. It leads to implications that can be tested with statistics. In particular, Big Players induce herding and, thereby, an increase of persistence in asset prices. A recent episode in Slovenian monetary theory provides a case study. This case study adds to a set of similar studies, all tending to support the theory of Big Players.     

Social risks and challenges in post-disaster resettlement: the case of Lake Nyos,Cameroon

This paper examines contemporary challenges in post-disaster resettlement in Cameroon. The focus is on the ongoing post-disaster experiences of survivors who were resettled in seven camps after the Lake Nyos Disaster in 1986. Empirical data obtained at the Ukpwa Waindo resettlement camp were used for analysis of impoverishment due to relocation and resettlement. Cameroon’s weak macroeconomic situation that started a quarter century ago had serious consequences for the country’s socio-economic trends, which is partly responsible for the slow recovery of disaster survivors. However, an analysis of social vulnerability using Cernea’s Impoverishment Risk and Reconstruction model shows how the involuntary resettlement of disaster survivors has itself created deep seated socio-economic and cultural consequences. By analysing their socio-economic situation, this article shows that resettlement is not merely a housing solution, but a complex, multi-dimensional process, with potentially very high negative impact if not properly planned and implemented. Therefore, the lessons learnt from this resettlement experience can be applied to ensure that resettlement becomes an opportunity to improve resilience and living conditions of the stricken population, and reduce exposure to disaster risk. There is urgent need for the government to tackle these long-term socio-economic problems faced by the disaster survivors, and to develop an effective policy to reconstruct, protect, improve or at least restore the livelihoods of those subject to resettlement.     

Shifting the goal posts for design management in capital goods projects: 'design for maintainability'

Two case studies of capital goods projects, both of which were faced with new forms of demand for their products, are reported in this paper. In both cases, the contracting organisations involved were adjusting to new customer requirements for the long-term provision of the services associated with the capital goods they normally produced, rather than for the capital goods themselves. While both contracting organisations recognised the need to re-focus their equipment design efforts, to reflect the need for long-term service reliability (both contracting organisations were tied to penalties associated with agreed service levels), they nevertheless responded differently to this challenge, and their differing responses reflected the differing natures of the extended networks which comprised both projects and the organisational architectures in which the projects were themselves embedded. The paper explores the differing opportunities and barriers to the management of design in complex projects presented by these two case studies. In so doing it points to the conclusion that successful design management in complex projects can depend upon the successful management of the (multiple) contexts in which design takes place.
