Portfolio efficiency analysis with SFA: the case of PSI-20 companies

This study aimed to assess the technical efficiency (TE) of individual companies and their respective sectors that are traded on the Portuguese stock market. We accomplished this by combining the internal input variables (e.g., ‘market value and return’) with exogenous variables (e.g., ‘interest income’, ‘depreciation’, ‘cost of goods’, ‘employees’ and ‘net sales’) into a Stochastic Frontier Analysis (SFA) model. The TE of the PSI-20 (Portuguese Stock Index) was estimated using factors that affect efficiency variability. The main advantage of using the SFA approach is its potential to discriminate between measurement error and systematic inefficiencies in the estimation process. The results demonstrated that TE is higher for enterprises in the industrial, construction and distribution sectors, whereas the commercial banking sector has the lowest TE scores. The ‘employees’ and ‘depreciation’ are the variables which most contribute to stock market inefficiency.     

Cultural Identity and Securitising the Korean Peninsula: Transformations in the South Korean Security Narrative

In response to enlargement, the EU’s ‘Wider Europe’ initiative and emerging European Neighbourhood Policy envisage ‘positive interdependence’ with neighbouring countries of the ‘East’ and ‘South’. ‘Partnerships’ are seen as an alternative to direct EU membership and thus as a sustainable incentive for regional cooperation. In order to be effective, such regional partnerships must transcend market logics and accommodate heterogeneous economic and socio-political realities. However, Wider Europe is characterised, in terms of realpolitik, by competing rationales of ‘stability’, ‘prosperity’, ‘sustainability’ and ‘security’ and thus by considerable potential for exclusionary policies. It is unclear whether exclusion can be counterbalanced by multilevel and ‘de-centred’ forms of regional engagement that also define Wider Europe. Applying a pragmatic approach, discussion will centre on rationales, discourses and reconceptualisations of European space upon which the notion of Wider Europe is being constructed and on whether they signal gradual changes in the direction of a ‘post-Westphalian’ geopolitics.     

Utopia competition: a new approach to the micro-foundations of sustainability transitions

We present a new evolutionary political economy approach to the study of transition dynamics based on a co-evolutionary model of differential citizen contributions to competing ‘utopias’—market fundamentalism, socialism, and environmentalism. We model sustainability transitions as an outcome of ‘utopia competition’ in which environmentalism manages to coexist with the market, while socialism vanishes. Our simulation-based framework suggests that the individual economic contributions of citizens to the battle of ideas—both the distribution within a utopia, and the interaction between different utopias—are crucial but much overlooked micro-factors in explaining the dynamics of sustainability transitions.     

Impacts of price variations on the balance of world trade

A standard mathematical model of a trade market is considered, and the concept of an acceptable state of the market is introduced, which takes into account the requirements of all the partners. To evaluate the ‘distance’ between the acceptable and current states of the market, a special mathematical approach is developed. This approach has been found useful for correcting the price vector to bring the states closer together.     

Banks as Continuous Reinvention

Of the several debates that revolve around the work of the economic historian and political economist Karl Polanyi, one that continues to exercise minds concerns his analysis of, and political attitudes toward, post-war capitalism and the welfare state. Simplified a little, it is a debate with two sides. To borrow Iván Szelényi's terms, one side constructs a ‘hard’ Karl Polanyi, the other a ‘soft’ one. The former advocated a socialist mixed economy dominated by redistributive mechanisms. He was a radical socialist for whom the market should never be the dominant mechanism of economic coordination. His ‘soft’ alter ego insisted that the market system remain essentially intact but be complemented by redistributive mechanisms. The ‘double movement’ – the central thesis of his ‘Great Transformation’ – acts, in this reading, as a self-correcting mechanism that moderates the excesses of market fundamentalism; its author was positioned within the social-democratic mainstream for which the only realistic desirable goal is a regulated form of capitalism. In terms of textual evidence there is much to be said for both interpretations. In this article I suggest a different approach, one that focuses upon the meaning of Polanyi's concepts in relation to their socio-political and intellectual environment.     

Money power of Capital and Production of ‘New State Spaces’: A View from the Global South

An array of innovative financial and monetary institutional and policy initiatives recently emerged across the Global South at various spatial scales: (1) the deployment of national ‘self-insurance’ strategies such as large foreign reserve accumulation, different forms of capital controls, and currency market interventions; (2) the multiplication of bilateral, sub-regional, and regional financial and monetary mechanisms, including currency swaps and reserve-pooling arrangements, credit lines, bilateral aid, and development finance; and (3) a growing participation and assertiveness in multilateral financial arrangements. After critically reviewing the existing literatures – the international political economy (IPE) of ‘policy space’ and the IPE of ‘financial statecraft’ – the paper deploys a ‘scalar-relational’ critical IPE approach and interprets these policy initiatives in terms of a crisis-driven production of ‘new state spaces’ across the Global South, in the context of the current period of credit-led capital accumulation. The paper argues that this process has been characterised by the contradictory extension, intensification and growing complexity of the tasks taken on by the capitalist state at various scale levels, resulting in the increasing entanglement of state power in the nested hierarchy of monetary relations, from the global scale to bodies and subjectivities.     

Theorizing the Financial Statecraft of Emerging Powers

‘Financial statecraft’, or the intentional use of credit, investment and currency levers by the incumbent governments of creditor – and sometimes debtor – states for both international economic and political advantage, has a long history, ranging from money doctors to currency wars. A neorealist, zero-sum framing of international monetary relations is not inevitable, yet casts a persistent shadow especially during periods of prospective interstate power transitions when previously peripheral countries find themselves with unexpected new capabilities. This article seeks to understand and theorise the financial statecraft of emerging economies, moving beyond the traditional understanding that closely identifies the concept with financial sanctions imposed by a strong state on a weaker state. We propose that the aims of financial statecraft may be either ‘defensive' or ‘offensive’. Financial statecraft may be targeted either ‘bilaterally' or ‘systemically’. Finally such statecraft may employ instruments that are either ‘financial' or ‘monetary’. As emerging market economies have moved up in the ranks in the interstate distribution of capabilities, they have also expanded their financial statecraft strategies from narrowly defensive and bilateral to those involving offensive tactics and targeted at the global and systemic level. Historical and contemporary examples illustrate the analysis.     

Innovation and the demand for food and drug labelling regulation in an evolutionary model of industry dynamics

Product innovation is examined in the context of an evolutionary model of industry and market behaviour in which a new product with a cost advantage and an unobservable, adverse characteristic competes with an existing product. Absent regulatory responses that ensure credible labelling, markets converge to steady state equilibria in which only the new product is traded. With credible labelling, the markets for the commodities become segmented. Welfare effects for consumers depend on the distribution of labelling ‘property rights’ between new and old product firms, market access, the cost advantage of the new product, and the magnitude of labelling costs     

Volatility and stock price indexes

The stochastic approach to index numbers has been successfully applied to the estimation of inflation, the world interest rate and international competitiveness.?One distinct advantage of this approach is that it provides the whole distribution of the index, not simply one value. In this article, we extend the stochastic approach to the estimation of a stock market index. We demonstrate how this approach can be used to identify ‘redundant stocks’ that do not contribute significantly to the overall index.?For index tracking purposes, these stocks can be safely excluded.     

Portfolio performance with controlled variables in the Singapore Stock Market

Recently, many stock return ‘anomalies’ have been identified. This leads to increasing agreement among researchers that these anomalies are relevant to enhancing investment performance. This study examines the existence of stock return anomalies on the Stock Exchange of Singapore in the period 1979–87, using a behavioural approach. The results reveal that the impact of anomalies on stock returns is unstable, with the direction of the impact determined by the strength of the stock market. This phenomenon and other observed anomalies may be partially explained by investors' psychology.     

On the diffusion of toilets as bottom of the pyramid innovation: Lessons from sanitation entrepreneurs

There is an emerging body of literature on product innovations for the poor at the bottom of the income pyramid. However, there is little on why delivery systems succeed or fail in this context and the present paper attempts to fill this void by examining why and how sanitation entrepreneurs are succeeding in India to diffuse toilets — an innovation for rural households, which never had access to one before. The literature is analyzed and confronted with the actual field practices. We demonstrate that the common thread that unifies progressive sanitation entrepreneurs is their adoption of a ‘market based approach’. There are market failures stemming from the demand side due to problems in expression of demand and its mismatch with the perceived value of the innovation. In response, sanitation entrepreneurs go beyond the standard linear model of assessing need and appropriateness of technology. They create innovations in ‘technological design’ as well as in the ‘delivery platforms’ to include practices for ‘accompaniment’, ‘sustainable maintenance’ and ‘generation of knowledge'. Thus, they make-up for sluggish or missing markets and informational asymmetries to ensure sustained use of toilets.     

Inflation news and stock returns: market direction and flow-through ability

Previous studies of the short-run response of daily stock prices to announcements of macroeconomic news could be biased when responses in different scenarios cancel each other out. In our analysis of inflation news in the Spanish stock market, we consider market direction arguments and implement our study based on the sector of activity to control for the ‘flow-through’ ability of the firms in each industry. In general, our results are quite consistent with the ‘market direction’ and the ‘flow-through’ hypotheses. Unanticipated inflation news implies abnormal returns depending on the direction of the news, the state of the economy and the flow-through ability of the sector. The impact of positive surprises affects the abnormal returns of many more sectors than does the impact of negative surprises, especially in the low states of economy. These significant effects are mainly observed in industries that are characterised by low flow-through ability.     

On the nature of the capitalist state ∗

We assesss critically three existing economic perspectives, the neoclassical, the Austrian and the Marxist, on the question of the ‘nature of the capitalist state’. In particular we address the questions of the existence of the state, the state's ‘principal’, the principals' objectives and the growth and evolution of the state, and consider the answers provided by the three perspectives. We find all three perspectives limited, particularly in their treatment of history and dynamics. We suggest that the adoption of a dynamic perspective with historical considerations provides original and useful insights on the above questions and on the issues of ‘state autonomy’. We conclude that the capitalist state can be usefully regarded as an institutional device for the exploitation of the specialization and division of labour complementary to markets and firms, which driving force is the furthering of the interests of its principals (a controlling subject of the population), but subject to coonstraints, such as voting and exit.     

The bank lending channel of monetary policy in EU countries during the global financial crisis

The study examines the existence of the bank lending channel of monetary policy in European Union (EU) countries. The paper advances current research on the monetary transmission mechanism in the following ways: Firstly, we analyze the differences between ‘old’ Economic Monetary Union (EMU) and ‘new’ EU countries. Secondly, we examine the key bank characteristics and monetary policy indicators that may have an impact on the bank lending channel. We assume that short-term market interest rates and monetary aggregate M2 affect banks' activities. We apply the generalized method of moments (GMM) with pooled data from 1999 to 2012. We show that in the pre-crisis period the effect of changing the short-term market interest rates on the bank lending channel of monetary policy is more pronounced among ‘old’ EMU countries, whereas the effect of M2 is significant during the period of the global financial crisis (GFC) among ‘old’ EMU countries. Last but not least the important finding is that banks in ‘new’ EU countries react differently to monetary shocks.     

Theorising the Korean State beyond Institutionalism: Class Content and Form of ‘National’ Development

Although the Korean developmental state has been heavily discussed in various disciplines and across diverse political spectrums, the statist notion that the developmental state is autonomous from and disciplines society, and is therefore effective in achieving ‘national development’, has more often been taken for granted than problematised. Statism is also pervasive in institutionalism that emphasises the linkages rather than dichotomies between state and market and in the recent discussions on the transformation of the developmental state. This article proposes an alternative conceptual framework by reformulating ‘the form critique of the state’ pioneered by Evgeny Pashukanis and further developed in the ‘German state derivation debate’ on the one hand, and ‘world system analysis’ on the other. Extending the Marxist critique of ‘commodity fetishism’ to the theorisation of the developmental state, it inquires into the origins of statism and argues that it is the uneven dynamics of capitalism as a global system that give rise to statism in the first place.     

Monetary Expressions of Labour Time and Market Prices: Theory and Evidence from China,Japan and Korea

This article presents estimates of labour values and prices of production following two approaches: the first is based on the classical and Marxian theory of value and distribution; the second on the so-called ‘new solution’ to the ‘transformation problem’ and its variant, the Temporary Single-System Interpretation (TSSI). The major advantage of the latter approach is its simplicity, along with the relatively low data requirements. Our empirical findings from the economies of China, Japan and South Korea suggest that both approaches give estimates of labour values and prices of production which are extremely close to each other as well as to actual market prices. On further examination, however, we conclude that our empirical findings are absolutely consistent with the theoretical requirements of the classical approach and contradict those of the TSSI.     

Goals,rationality criteria and market functioning ∗

The behaviours of economic operators may be directed by goals and rationality criteria other than those postulated by neoclassical theory. Under certain conditions, the existence of deviant goals and rationality criteria, far from being eliminated by the process of ‘natural selection’, has a profound effect on market functioning. It alters the ‘natural selection’ criterion and thereby influences the market trajectory. It can also favour the development of specific mechanisms of co-ordination. Our hypothesis is illustrated by an analysis of the cultural markets.     

Fiscal policy and capital mobility: the construction of economic policy rectitude in Britain and France

This research examines the regulatory response of the European Union to the global financial crisis, addressing the questions of whether, how and why the global financial crisis has changed the ‘old’ politics of financial services regulation in the EU and resulted in the emergence of a ‘new’ politics. It is argued that, with a good dose of political opportunism and ‘anti-free market’ rhetoric, a continental advocacy coalition sponsoring a ‘market-shaping’ regulatory approach has capitalised on the crisis, tipping the balance of regulatory power in the EU in its favour, as compared to the pre-crisis situation.     

The regulation of unstable growth: I'éecole de régulation and the social structure of accumulation

The economic growth condition of parallel developments in consumption and production has been placed by the French regulation school and the social structure of accumulation approach in the policy context of the distribution of class income. The implications are that there exists some unique income distribution compatible with growth, and that the post-1973 growth slowdown was the cause of labour becoming so strong as to ‘weaken’ capital. This condition of growth has close affinity with early growth theory and is presented here in terms of a Harrod-Domar ‘knife-edge’ instability. Starting from this perspective, I argue first, that the conditions of long-term growth cannot be applied to medium-term policy horizons, and secondly, that this domestic regulation is no longer dominant in an international environment in which national economies have increasingly become more open to trade and/or capital transfers. This consideration, illustrated by the instances of Canada and the NICs, suggests the existence of a different form of growth/income regulation in which the ‘knife-edge’ is exported. The policy implications for the national labour movement is then more complex and perhaps less constraining than that suggested by the two approaches under discussion.     

The emergence of convergent price clusters in China

This paper reports new evidence on the existence of both large and small price divergent clusters for China's energy markets, 2000–2009. The largest convergent price clusters suggest that the coal and gasoline markets are well integrated, however, small convergent price clusters suggest that electricity and diesel markets are proving harder to integrate. The paper argues that the traditional approach to price convergence analysis should be applied with caution, especially in a transitional economy such as China where questions to be asked should relate to the ‘degree of market‐orientation’ and not simply whether it is a market‐based economy or not.
