Abstract:
During the world food crisis of 2007-08, the price of staples soared rapidly. Higher food price impacts poor households more as they spend approximately three quarters of their income on food. Together rice and wheat provide more than 50% of the calorific intake in India. Apart from providing food security, millions of poor and small farmers depend on rice for their livelihoods. Using Indian Consumer Household Expenditure surveys for the years 2007-08 and 2009-10 the paper analyses the welfare generated by a ban on export of rice by the Indian government. The paper finds that the net impact of the ban on export of rice was positive, as it was able to cushion the Indian population (87% of whom are net consumers) from the adverse effects of the crisis. It also found that the poor in India aren’t homogeneous in nature. The majority of the rice-producing households that stand to gain from increased prices are relatively poor farmers. At the same time, the poor households that do not cultivate rice are most affected by price increase, as their budget share of rice is higher than richer households, who are more resilient to price rise. In particular, the wage labourers are affected significantly.

2. A Paradigm Shift thatNever Will Be?:Justin Lin’s New Structural Economics (pdf)

Abstract:
This paper assesses the attempt by Justin Lin, former Chief Economist of the World Bank, to posit a new development paradigm through his New Structural Economics, NSE. Lin’s attempt to redefine development economics deserves scrutiny for at least two reasons. He launched his new framework from the platform that his position as Chief Economist at the Bank. Critical scrutiny of his propositions then allows for continued insights into the complex relationship between scholarship and policy at the Bank and further illuminates, more broadly, the role of the Bank across the spectrum of development economics, development studies and development policy. Second, Lin’s framework claims a return to a “structural” understanding of development, with a strong industrial policy rhetoric emanating from it. This has been greeted with considerable enthusiasm by erstwhile critics of the Bank. Closer scrutiny of the NSE, however, both reveals the flawed nature of its core theoretical notion of comparative advantage and exposes its strong, if unfortunately conservative, commitment to a flawed and incoherently applied neoclassical economics. These issues are explored across Lin’s propositions regarding structural change, the role of the state and finance and are further examined in the context of specific policy interventions that Lin attaches to the NSE.

3. A Note on Credit Allocation, Income Distribution, and the Circuit of Capital (pdf)

Author:
Paulo dos Santos
Publication Date:

Content Type:
Working Paper
Institution:
School of Oriental and African Studies - University of London
Abstract:
This note considers the relationship between credit allocation and the aggregate, class distribution of income in the Circuit of Capital. Production and consumption credit inject means of purchase in different locations in the monetary circuits of capitalist reproduction. On the basis of comparative-dynamic analysis of the properties of steady-state evolutions, the note shows that production credit increases the wage share in total income, while consumption credit increases profit shares. These findings hold in general for any evolution in which sectoral revenue- elasticities of outlays measure less than unity. The note also motivates a new endogenous approach to the aggregate distribution of income, and offers new analytical tools facilitating work based on demand-constrained models of the Circuit of Capital.

4. Financing Water in Africa

Working Paper

School of Oriental and African Studies - University of London
Abstract:
Despite repeated policy initiatives from donors and governments, the human and economic cost of continued lack of access to safe water and sanitation in sub‐Saharan Africa remains high. This paper shows that a radical reorientation of policy is needed to achieve a significant increase in investment finance in order to raise access levels. Rather than continuing to pursue policies that have failed for the past two decades, such as bringing in the private sector and raising prices to cost recovery levels, attention needs to shift to wider aspects of domestic revenue mobilization to support public investment.

5. A History of Polyvalent Structural Parameters: the Case of Instrument Variable Estimato

Author:

Content Type:
Working Paper
Institution:
School of Oriental and African Studies - University of London
Abstract:
This paper investigates the rise and fall of the IV method in macro-econometric models and its subsequent revival in micro-econometric models. The key findings are: (i) the IV method implicitly breaks the contemporaneously circular causality postulated in a simultaneous- equation model (SEM) by redefining the conditional variable concerned as a suboptimal conditional expectation of it; (ii) the IV method falls out of favour in macro-econometrics mainly because of lack of empirical validations for such redefinitions; (iii) the IV method wins its popularity in micro-econometrics by its capacity to produce multiple suboptimal conditional expectations of the latent conditional variables of interest under the disguise of an SEM consistent estimator; nevertheless, (iv) such suboptimal conditional expectations give rise to the insurmountable difficulty of credibly interpreting the IV-based parameter estimates, especially in the case of prognosticated omitted variable bias. The findings highlight the methodological drawback of the estimator-centric strategy of textbook econometrics.

6. Modelling Scale Effect in Crosssection Data:The Case of Hedonic Price Regression

Content Type:
Working Paper
Institution:
School of Oriental and African Studies - University of London
Abstract:
An innovative and simple experiment with cross-section data ordering is carried out to exploit a basic and common feature between many economic variables – nonlinear scale dependence. The experiment is tried on hedonic price regression models using two data sets, one for automobiles and the other computers. The key findings are: (a) Hedonic price indices can be significantly biased if they are constructed using models which disregard possible nonlinear scale effects latent in random data samples; (b) Scale-based data ordering offers considerable potential to filter such scale-dependent information from cross-section samples; (c) The filtering can be easily carried out by systematic adoption of dynamic modelling methods.

7. Price Non-Convergence in Commodities: A Case Study of the Wheat Conundrum

Abstract:
The close relationship between commodity future and cash prices is critical for the effectiveness of risk management and the functioning of price discovery. However, in recent years, commodity futures prices, across the board, have appeared increasingly detached from prices on physical markets. This paper argues that while various factors, identified in previous literature, which introduced limits to arbitrage have facilitated non-convergence, the actual extent of non-convergence in these markets is caused by essential differences in the mechanisms of price formation on physical and derivative markets. With reference to the particular case of the CBOT wheat market, the paper shows that the size of the spread between futures and cash prices can be theoretically and empirically linked to the increasing inflow of financial investment into commodity futures markets.

8. Capital Flows to Emerging Markets: An alternative Theoretical Framework

Author:
Bruno Bonizzi
Publication Date:

Content Type:
Working Paper

School of Oriental and African Studies - University of London
Abstract:
This paper represents a theoretical contribution to the analysis of international capital flows. It outlines an alternative theoretical framework based on Post-Keynesian monetary theory, and in particular on Hyman Minsky’s Wall Street paradigm and concept of Money-manager capitalism and Jan Toporowski’s theory of capital market inflation. The key aspects of such an approach are, firstly, that in a monetary analysis capital flows need to be understood as “flows of funds”, as opposed to the traditional understanding of capital flows based on “real” decision, such as saving and investment. A consequence of this is the need of focusing on gross rather than net capital flows. Secondly, when considering emerging markets, the asymmetric nature of the international monetary system must be stressed. Thirdly, it is important to understand the specific forms that capital flows take: in today’s world, pension funds and other institutional investors — alongside banks — are key players in the financial markets, and their role in shaping capital flows to emerging markets must be explicitly recognised. This paper synthesises these elements by understanding capital flows as the result of institutional investors portfolio choice. Along the lines of Minsky and Toporowski, portfolio choice by institutional investors need to be assessed in relation to their balance sheet structure, beside risk/return trade-offs and general state of risk aversion

9. Corporate Liquidity and Financial Fragility: The Role of Investment, Debt and Interest

Author:
Jan Toporowski

School of Oriental and African Studies - University of London
Abstract:
The paper addresses the issue of how debt deflation may arise in a capitalist economy with a sophisticated credit system. It argues that the standard argument of debt deflationists, that debt-financed investment causes a build-up of unsustainable investment, fails to recognise that debt is back by credit. A corollary of this is that the rate of interest is not a factor in investment decisions. Financial fragility is caused by heterogeneity of balance sheets, debt financed operations in financial markets and insufficient debt-financed investment, rather than too much such investment.

10. Lange and Keynes

Author:

Publication Date:

Content Type:
Working Paper
Institution:
School of Oriental and African Studies - University of London
Abstract:
Lange engaged with Keynes in the matter of Keynes‟s macroeconomics, and over econometrics. Lange‟s interpretation of the Keynesian macroeconomic model laid the foundation for the neo-classical synthesis. But it was limited in its monetary economics. Lange also intervened in the Keynes-Tinbergen dispute over the scope and significance of econometrics. Lange collaborated in a paper that conceded Keynes‟s main point that empirical investigation could not determine theory, but insisted that theories could nevertheless be tested empirically. The paper was never publish and Keynes, unconvinced, planned to recruit Kalecki to his critique of econometrics.
