Relations of Production and Modes of Surplus Extraction in India
This paper uses aggregate-level data, as well as case-studies, to trace out the evolution of some key structural features of the Indian economy, relating both to the agricultural and the informal industrial sector. These aggregate trends are used to infer: (a) the dominant relations of production under which the vast majority of the Indian working people labour, and (b) the predominant ways in which the surplus labour of the direct producers is appropriated by the dominant classes. This summary account is meant to inform and link up with on-going attempts at radically restructuring Indian society.

The impact of e-business technologies on supply chain operations: a macroeconomic perspective
New information technologies and e-business solutions have transformed supply chain operations from mass production to mass customization. This paper assesses the impact of these innovations on economic productivity, focusing on the macroeconomic benefits as supply chain operations have evolved from simple production and planning systems to today's real-time performance-management information systems using advanced e-business technologies. While many factors can influence macroeconomic variables, the impact of IT-enabled supply chains should not be overlooked. We find evidence that the impact of e-business technologies on supply chain operations have resulted in a reduced "bullwhip effect," lower inventory, reduced logistics costs, and streamlined procurement processes. These improvements, in turn, have likely helped to lower inflation, reduce economic volatility, strengthen productivity growth, and improve standards of living.Information technology ; Macroeconomics ; Productivity
On self-sustained oscillations in two-dimensional compressible flow over rectangular cavities
Numerical simulations are used to investigate the resonant instabilities in two-dimensional flow past an open cavity. The compressible Navier–Stokes equations are solved directly (no turbulence model) for cavities with laminar boundary layers upstream. The computational domain is large enough to directly resolve a portion of the radiated acoustic field, which is shown to be in good visual agreement with schlieren photographs from experiments at several different Mach numbers. The results show a transition from a shear-layer mode, primarily for shorter cavities and lower Mach numbers, to a wake mode for longer cavities and higher Mach numbers. The shear-layer mode is characterized well by the acoustic feedback process described by Rossiter (1964), and disturbances in the shear layer compare well with predictions based on linear stability analysis of the Kelvin–Helmholtz mode. The wake mode is characterized instead by a large-scale vortex shedding with Strouhal number independent of Mach number. The wake mode oscillation is similar in many ways to that reported by Gharib & Roshko (1987) for incompressible flow with a laminar upstream boundary layer. Transition to wake mode occurs as the length and/or depth of the cavity becomes large compared to the upstream boundary-layer thickness, or as the Mach and/or Reynolds numbers are raised. Under these conditions, it is shown that the Kelvin–Helmholtz instability grows to sufficient strength that a strong recirculating flow is induced in the cavity. The resulting mean flow is similar to wake profiles that are absolutely unstable, and absolute instability may provide an explanation of the hydrodynamic feedback mechanism that leads to wake mode. Predictive criteria for the onset of shear-layer oscillations (from steady flow) and for the transition to wake mode are developed based on linear theory for amplification rates in the shear layer, and a simple model for the acoustic efficiency of edge scattering

Non-Food Expenditures and Consumption Inequality in India
This paper contributes to the ongoing debate about economic inequality in India during the post-reform period. We analyze consumption inequality through the hitherto neglected lens of nonfood expenditure. Using household level consumption expenditure data from the quinquennial “thick” rounds of the NSS, we show that inequality within food and non-food groups has declined, even as overall expenditure inequality has increased over time. We suggest that the rise in overall expenditure inequality is due to the increased weight in the household budget of non-food spending, which tends to be more unequal than food spending. We also show that inequality is very different across broad non-food items. Durables, education, healthcare, and consumer services show the most rapid increases in real expenditure, and also display the highest levels of inequality. Finally, we offer some possible mechanisms for this phenomenon and suggest policy measures to deal with this form of inequality
