A Post-Keynesian Response to Piketty's ‘Fundamental Contradiction of Capitalism’

In Capital in the Twenty-First Century, Thomas Piketty presents a rich set of data that deals with income and wealth distribution, output-wealth dynamics and rates of return. He also proposes some ‘laws of capitalism’. At the core of his argument lies the ‘fundamental inequality of capitalism’, an empirical regularity stating that the rate of return on wealth is greater than the growth rate of the economy. This simple construct allows him to conclude that increasing wealth (and income) inequality is an inevitable outcome of capitalism. While we share some of his conclusions, we will highlight some shortcomings of his approach based on a Cambridge post-Keynesian growth-and-distribution model. The paper makes four points. First, r?>?g is not necessarily associated with increasing inequality in functional distribution. Second, Piketty succumbs to a fallacy of composition when he claims that a necessary condition for r?>?g is that capitalists save a large share of their capital income. Third, post-Keynesians can learn from Piketty's insights about personal income distribution and incorporate them into their models. Fourth, we reiterate the post-Keynesian argument that a well-behaved aggregate production function does not exist and cannot explain income distribution.     

A new contribution to the ‘Paris Metro Pricing’ proposal

Using the concept of the ‘Paris Metro Pricing’, we will show that, when the distribution of the capacity between sub-networks leads to any loss of technical effectiveness and when a traditional condition on the ‘hazard rate’ is checked, it is always optimal for the monopolist to subdivide his main network in as many sub-networks as there are different types of net surfers.     

Separation of powers and the erosion of the ‘right to property’ in India

There has been a substantial erosion of the ‘right to property’ with respect to state takings in India, reflected in a progression of amendments to the Indian Constitution. Among other things, these amendments signify a violation of the doctrine of separation of powers. To study the implications of this on governance in relation to state takings, this paper juxtaposes a narration of events that describe the progressive erosion of the ‘right to property’ against a heuristic analytical structure that seeks to capture the costs of violating the doctrine of separation of powers. This analysis is then utilized to point to the social costs that characterize the state acquisitions (takings) regime in India.

Sensitivity of ‘optimal’ commodity tax rates to alternative demand functional forms: An econometric case study of India

This study investigates, on a nine commodity disaggregation of Indian budget data (NSS, 28th round), the sensitivity of ‘optimal’ commodity tax rates to alternative demand systems. LES and RNLPS. ‘Optimality’ is used here in the very special sense of being conditional on observed expenditure and fixed consumer prices. The alternative sets of tax rates agree at low levels of ‘inequality aversion’ but disagree widely at ‘Rawlsian’ levels. LES is heavily rejected in favour of its one-parameter generalisation, RNLPS. The results suggest that LES price elasticities should not be used in ‘optimal’ tax calculations. The ‘optimal’ tax rates imply only a modest redistribution.     

Determinants of India’s Exports

The objective of this paper is to examine the key determinants of India’s exports. The estimated equations show that the two variables influencing India’s export demand are the real effective exchange rate and world exports. The time trend variable which was introduced to take care of the stationarity problem and India’s GDP which is a proxy for availability also are statistically significant. Equations were also estimated at a disaggregated level of commodity groups. The article also focuses on measuring the relative contribution of the variables. For this, a new methodology is proposed. World exports which emerges as the dominant variable is however exogenous to Indian policy makers. This leaves nominal exchange rate as the tool available to policy makers. In the market determination of exchange rate, besides current account deficit, capital flows also play an important part. There is need to moderate the impact of large capital inflows on exchange rate through appropriate intervention so long as we continue to have current account deficit. An appreciating currency will erode the competitiveness of exports. Truly speaking, the critical factor is not so much exchange rate as competitiveness. In this context, maintaining domestic price stability and improving the productivity, particularly of the traded goods sector are equally important.

     

The reason for ‘The Reason of Rules’

This paper is an attempt to locate the writing of the book, The Reason of Rules, in its intellectual and temporal setting. The object is to capture something of the ambitions of the book and to assess its limitations as perceived three decades after its writing. It includes some personal reflections on the experience of Buchanan as a co-author.     

Building ‘mass’ and ‘momentum’ – a latecomer country’s passage to large technological systems – the case of China

This paper focuses on how a latecomer country can bring a large (infrastructural) technological system (LTS) to a market already dominated by the entrenched systems of global technology leaders. We construct a conceptual framework, building on Hughes LTS theory (1983) and insights from social studies of technology into the specificities of infrastructural sociotechnical systems to analyse the development of China’s 3rd Generation mobile telephony system. We explore the complex dynamics surrounding the distributed governance of innovation, highlighting changes in key system builders. We note the role of the state in addressing critical problems (‘reverse salients’), both in terms of aligning players through legitimating and sense-making and also, building the necessary mass and momentum. This includes a more radical reconfiguring of the field to secure the substantial commitments needed to materialise and embed a new LTS infrastructure.     

The political economy of decarbonisation: from green energy ‘race’ to green ‘division of labour’

This paper aims to provide an addendum to the rapidly growing concept of a global ‘green energy race’ between major states. It argues that although this framing has been useful in underscoring important dynamics in the process of decarbonisation, its narrow focus on installed capacity obscures a much broader and more complex process at play. In particular, it overlooks the critical role played by states aggressively investing in R&D and export manufacturing in the renewable energy sector. The paper thus supplements the concept of a green ‘energy race’ with that of a green ‘global division of labour’, which sees the process of decarbonisation not exclusively as an effort by individual states to install renewables domestically, but rather as a collective and interdependent process by dozens of states, all striving in different ways to promote capital accumulation on their soil. The paper provides an overview of data covering innovation, manufacturing and deployment in the clean energy sector, and offers a theoretical analysis of the trends observed.     

‘On the Econ within’: a reply to Daniel Hausman

This note replies to a comment by Daniel Hausman on our paper ‘Preference purification and the inner rational agent: a critique of the conventional wisdom of behavioural welfare economics’. We clarify our characterisation of behavioural welfare economics and acknowledge that Hausman does fully endorse this approach. However, we argue that Hausman’s response to our critique, like behavioural welfare economics itself, implicitly uses a model of an inner rational agent.     

Critical reflections on a realist interpretation of Friedman’s ‘Methodology of Positive Economics’

Uskali Mäki has offered an innovative scientific realist account of Milton Friedman’s 1953 essay, ‘The Methodology of Positive Economics’, which directly challenges the dominant instrumentalist interpretation. This paper offers critical reflections on Mäki’s approach and interpretation. It is argued that Mäki’s method of rereading-rewriting the text is problematic; that an unforced instrumentalist account of unrealistic assumptions can be extracted from the text itself; and that seemingly realist passages can be plausibly read as expressing an instrumentalist stance.     

Bank capital,the state contingency of banks’ assets and its role for the transmission of shocks

I show how the evolution of bank capital depends on the share of non-state-contingent assets in banks’ balance sheets and present the implications for macroeconomic dynamics. State-contingent securities impact on banks’ balance sheets through changes in their returns (and their prices), both of which depend on the current state of the economy. Non-state-contingent assets are signed before shocks are realized and their repayment is guaranteed. For this reason, they insulate banks’ balance sheets from recent economic activity in the absence of defaults. Non-state-contingent assets in banks’ balance sheets attenuate the amplification of shocks resulting from financial frictions. The same effect can be achieved if more weight is placed on the state-contingent assets in the equity related constraint against the costs of long-run output losses.     

Employment impacts of a ‘green’ energy transition in China

Before the US financial crisis that began in 2008, China was the ‘factory’ of the world, utilizing energy intensively for such processes as steelmaking, papermaking and concrete production. As such, energy emissions in China increased dramatically until 2007, with much of the energy being provided by the labor-intensive coal industry. Under the 11th five-year plan, China resolved to increase its energy efficiency, setting out to reduce energy consumption while continuing to increase economic growth, and to increase the usage of ‘green’ technologies to 15% of all energy used by 2020. The Renewable Energy Law of 2007 set a guideline for China's energy reduction goals, to quadruple the national GDP while only doubling the country's electricity usage by the year 2020. Currently, there are virtually no studies on the employment effects of a ‘green’ transition to explore what impact the current energy goals, or potentially ‘greener’ energy goals, would have on China's labor force. This paper seeks to analyze the effects on employment of a ‘green’ transition.     

Response of industrial customers to hourly pricing in Ontario’s deregulated electricity market

This paper uses hourly data from Ontario (Canada) between 2005 and 2008 to estimate the effects of real time wholesale electricity prices on demand by industrial customers. Nonlinear SUR estimates from Generalized Leontief (GL) specifications reveal elasticities of substitution from 0.02 to 0.07, confirming that industrial customers (connected to the transmission grid) shift consumption across peak and off-peak periods in order to reap benefits of lower prices. Estimates from FGLS and IV models suggest that this reduction in demand by industrial customers results in lower wholesale prices, which benefits all consumers. The policy lesson is that market based schemes that encourage Real Time Pricing (RTP) pricing should result in positive spillovers to all consumers.     

Dominance testing for ‘pro-poor’ growth with an application to European growth

This article introduces statistical testing procedures to evaluate ??pro-poor?? growth. Our measure of ??pro-poorness?? follows Kakwani (J Quant Econ 16(1):67?C80, 2000), Kakwani and Pernia (Asian Dev Rev 18(1):1?C16, 2000), and Son (Econ Lett 82:307?C314, 2004), who decompose the generalized Lorenz ordinates into a growth effect and an inequality effect. We derive an asymptotic distribution-free covariance matrix for the decomposed generalized Lorenz curves. Using this decomposition (and our standard errors), we test for pro-poor dominance in the growth process. We illustrate our test for the pro-poor dominance by evaluating the degree of pro-poor growth in five European countries.     

Reappraisal of outbound open innovation under the policy of China’s ‘Market for Technology’

China’s ‘Market for Technology’ policy has attracted much interest over the past decade. In light of a relative emphasis on the spillover effects of joint ventures, this study examines the transferring effects of Multinationals’ (MNCs) outbound open innovation in such a context. A survey of 2071 research and development (R&D) contract transactions between Chinese entities and MNCs indicates both internal factors (e.g. organisational capabilities) and external factors (e.g. the role of Intellectual Property protection) affect the transferring effects, which reformulate the focus of the Policy from the relational dimension of ‘Government vs. MNCs’ to the transactional dimension of ‘Domestic entities vs. MNCs’. We thus conclude that MNCs’ active initiative in the involvement of technology transfer and the success of domestic transaction partners combine to contribute to the technology progress within China’s ‘Market for Technology’ policy.     

Polanyi’s ‘substantive approach’ to the economy in action? Conceptualising social enterprise as a public health ‘intervention’

For several decades now, critical public health researchers have highlighted the deleterious effects that pursuing neoliberal policies can have on the ‘causes of the causes’ of poor health and upon growing health inequalities. This paper argues that the conceptual tools of Karl Polanyi can help lend particular insight into this issue. The specific example that this paper focuses upon is the ‘social enterprise’: a form of organisation that combines both social and business objectives. The paper explores, conceptually, whether social enterprises may have the potential to act as one component of a neo-Polanyian countermovement: helping to re-embed the economy back into society, and offering greater recognition for a more comprehensive and socially imbued concept of health. Importantly, this potential is critically examined in the context of neoliberal hegemony, where challenges to the status quo have regularly been met with assimilation, co-option and/or repression.     

John R. Commons’s Foundations for Policy Analysis

Psychological insights have been present in institutional economics since its beginning. Recently, cognitive aspects of institutional economics have been highlighted. The proposal of this paper is to offer other psychological insights related to institutional economics, which are complementary to a cognitive approach. The goal is to emphasize elements of Psychological Social Learning Theory as a possible foundation of Institutional Economics. This paper argues that people vicariously learn by the observation and interpretation of exemplary behaviors. Vicarious learning relies on the comprehension of people about who/what models are. Vicariously, people are motivated to behave as a model; when they succeed, models are reinforced. As something socially and cumulatively acceptable and/or desirable, exemplary behaviors can take place repetitively and become a habit. Institutions arise as outgrowths of those habits. In this logic, a working definition of institution is a cognitive inertia about the typifications of foreseeable regularities in behaviors of people in a society.     

An assessment of two environmental and economic benefits of ‘Cash for Clunkers’

This research aims to provide a more comprehensive, life cycle accounting of two categories of environmental and economic benefits associated with the $3 billion US “Cash for Clunkers” vehicle scrappage program. First, using a life cycle emissions methodology developed in Lenski et al. (2010), we find that about 29,000 metric tons of criteria pollutant emissions were avoided, for a benefit of about $23 million; avoided carbon dioxide emissions, by comparison, provided a benefit worth $90 million. Second, we compare the market value of scrapped vehicles to the rebates provided, calculating the consumer surplus or “gift” to participants to be up to $2 billion (about $2000 to $3000 per vehicle). This is significantly more than offered in previous vehicle scrappage programs, and suggests opportunities to get more environmental and economic “bang for the buck.” Finally, these two categories of benefits are found to be heavily concentrated geographically around urban centers. About 2% of US counties (50 counties) received 50% and 30% of the aggregate benefits from avoided criteria pollutant emissions and consumer surplus from the rebates, respectively.     

Finding partners for complex system innovations through a trans-sectoral ‘matchmaking platform’

Complex system innovations require the concurrent implementation of trans-sectoral co-innovations. The case of fuel cell vehicle development in Germany may serve as an expedient example for this necessity to develop multiple innovative components within largely disconnected ‘technology islands’. The diagonal cooperation among organisations from formerly non-cooperating industries (i.e. from within those technology islands) that so far have not shared a common knowledge base, however, is hindered by structural information deficits, making it difficult to identify the ‘right’ cooperation partners. Based on the requirements as identified in the case study, we therefore propose a ‘matchmaking platform’ that aims at fostering a trans-sectoral dialogue by providing systematically generated corporate capability profiles of organisations with promising cooperation potential. The matching is grounded on factors derived from resource- and market-based theory.
