Wirtbarkeit : Cosmopolitan Right and Innkeeping

After defining Cosmopolitan Right as being limited to the conditions of “hospitality,” Kant includes “Wirtbarkeit” in brackets, a word which connotes innkeeping. Moreover, significant similarities obtain between the relevant passages of the Perpetual Peace and those of the Digest of Justinian on the obligations of ships’ masters, innkeepers, and stable keepers. Unlike ordinary householders, hospitality for innkeepers is a legal obligation, not a matter of philanthropy: they are deemed public officials with limited discretion to refuse travelers, and as fiduciaries of their guests strictly liable for losses to their property. Accordingly, this article attempts to explain Cosmopolitan Right at least in part by analogy to the private law of innkeeping. On this basis, it engages in the central philosophical debate about Cosmopolitan Right by accounting for Cosmopolitan Right solely from the “innate” right to freedom, rather than from “acquired” facts such as land or resource distributions or historical injustices

Trade Liberalization, Poverty and Food Security in India

This paper attempts to assess the impact of trade liberalization on growth, poverty, and food security in India with the help of a national level computable general equilibrium (CGE) model. It shows that GDP growth and income poverty reduction that might occur following trade liberalization need not necessarily result in an improvement in the food security / nutritional status of the poor. Evidence from simulations of (partial) trade reforms reflecting a possible Doha-like scenario show that the bottom 30% of the population in both rural and urban areas suffer a decline in calorie and protein intake, in contrast to the rest of the population, even as all households increase their intake of fats. Thus, the outcome on food security / status with regard to individual nutrients depends crucially on the movements in the relative prices of different commodities along with the change in income levels. These results show that trade policy analysis should consider indicators of food security in addition to overall growth and poverty traditionally considered in such studies.Doha negotiations, India trade policy, poverty, food security, CGE model

Load Balancing via Random Local Search in Closed and Open systems

In this paper, we analyze the performance of random load resampling and migration strategies in parallel server systems. Clients initially attach to an arbitrary server, but may switch server independently at random instants of time in an attempt to improve their service rate. This approach to load balancing contrasts with traditional approaches where clients make smart server selections upon arrival (e.g., Join-the-Shortest-Queue policy and variants thereof). Load resampling is particularly relevant in scenarios where clients cannot predict the load of a server before being actually attached to it. An important example is in wireless spectrum sharing where clients try to share a set of frequency bands in a distributed manner.Comment: Accepted to Sigmetrics 201

Collective modes and superflow instabilities of strongly correlated Fermi superfluids

We study the superfluid phase of the one-band attractive Hubbard model of fermions as a prototype of a strongly correlated s-wave fermion superfluid on a lattice. We show that the collective mode spectrum of this superfluid exhibits, in addition to the long wavelength sound mode, a sharp roton mode over a wide range of densities and interaction strengths. We compute the sound velocity and the roton gap within a generalized random phase approximation (GRPA) and show that the GRPA results are in good agreement, at strong coupling, with a spin wave analysis of the appropriate strong-coupling pseudospin model. We also investigate, using this two-pronged approach, the breakdown of superfluidity in the presence of a supercurrent. We find that the superflow can break down at a critical flow momentum via several distinct mechanisms - depairing, Landau instabilities or dynamical instabilities - depending on the dimensionality, the interaction strength and the fermion density. The most interesting of these instabilities is a charge modulation dynamical instability which is distinct from previously studied dynamical instabilities of Bose superfluids. The charge order associated with this instability can be of two types: (i) a commensurate checkerboard modulation driven by softening of the roton mode at the Brillouin zone corner, or, (ii) an incommensurate density modulation arising from superflow-induced finite momentum pairing of Bogoliubov quasiparticles. We elucidate the dynamical phase diagram showing the critical flow momentum of the leading instability over a wide range of fermion densities and interaction strengths and point out implications of our results for experiments on cold atom fermion superfluids in an optical lattice.Comment: 14 pages, 10 figures.

Reforms in Indian Agro-processing and Agriculture Sectors in the Context of Unilateral and Multilateral Trade Agreements

In this paper, we explore the potential impacts of trade and investment-related policy reforms on Indias agro-processing sector. We consider the direct effects of policy reforms within the processing sector, and the indirect effects on agro-processing of policy reforms in the primary agriculture sector, in the Indian economy as a whole, and in a multilateral framework. Towards this, we develop a 22-sector, 16-region version of the GTAP computable general equilibrium (CGE), global model for our analysis. We find that trade and investment-related reforms in agro-processing together can help the sector to grow. Policy reforms that stimulate investment and help to improve productivity will be crucial in offsetting the contractionary pressures of trade reform alone on the production of processed agricultural products. We also find that indirect effects on agro-processing from Indias policy reforms in other sectors are more important than reforms in agro-processing itself. Our findings argue for an economy-wide perspective when targeting reform or development of the agro-processing sector in India. Compared to trade reform, comprehensive domestic reforms in the agro-processing and agriculture sectors relating to investment are critical for achieving growth in agro-processing. However, while the impacts of trade reform per se seem to be small, trade reform - by ushering in a higher degree of competition - could itself be a stimulus for investment and productivity gains in India. At present, unilateral reforms, especially those that improve productivity in agro-processing and in primary agriculture, are more important to agro-processing than multilateral trade reforms. Nevertheless, our findings also suggest the importance of pursuing a domestic reform agenda within a multilateral trading strategy that can accommodate the expected economic growth of India and its future role in global markets, with general equilibrium effects on agro-processingagriculture, Agro-processing, Trade agreements, CGE models
