India and Its Television: Ownership, Democracy, and the Media Business

Abstract: With annual revenues of about $17 billion in 2012, India is among the world's top 15 global media and entertainment markets. While much attention has been focused in recent years on India's rise as an emerging economy, its great-power potential as the world's largest democracy and the future trajectory of its growth but the role of India's burgeoning media industry in this wider story is much less understood. For a country with the world's largest newspaper market, second largest telecommunications market, third largest television market and second largest Facebook community, the virtual absence of India from most mainstream global communications studies within academia is strange. In revenue terms, India's share of the global media sector still remains small but within the top 15 media and entertainment economies, only India has had consistent over-15 percent growth rates for years. Yet, outside of India, within the wider ambit of policy and international relations, few understand the crucial role Indian...

Fiscal Austerity in Emerging Market Economies

Abstract: We build a small open economy RBC model with financial frictions to analyze expansionary fiscal consolidations in emerging market economies (EMEs). We calibrate the model to India, which we view as a proto-typical EME. When factor income tax rates are low, a contractionary fiscal shock has an expansionary effect on output. The economy's debt/GDP ratio falls, and tax revenues rise. When factor income tax rates are high, a contractionary fiscal shock has an expansionary effect on output if government spending is valued sufficiently highly relative to private consumption by households in utility. We identify the mechanisms behind these results, and their implications for actual economies undertaking fiscal reforms.

Heterogeneity, Impatience and Dynamic Private Provision of a Discrete Public Good.

Abstract: We analyze dynamic private provision of a discrete public good by heterogeneous agents, who differ in terms of their level of impatience, in a differential game framework. We show that in the asymmetric MPE, the individual contributions and the strategic behavior depends crucially on impatience differential: the difference in the rates of time preferences between groups of individuals. When the differential is small, contributions of agents of both groups are strategic compliments. On the other hand, when this impatience differential is substantial, the contribution of relatively more impatient agents become strategic substitutes, whereas that of patient agents remain strategic compliments. We show that group size has an interesting role to play in the strategic behavior: increasing the number of patient individuals enhances the incidence of free riding by the impatient agents. We also derive a condition under which all the socially beneficial projects gets completed in the equilibrium.

Enhanced efficiency of PbS quantum dot-sensitized solar cells using plasmonic photoanode

Abstract: In this report, an effort has been made to develop an efficient PbS quantum dot-sensitized photoanode by simple successive ionic layer adsorption and reduction technique to enhance the overall photovoltaic performance of PbS quantum dot-sensitized solar cells. Three strategies have been adopted for the improvement of the photovoltaic performance of PbS quantum dot-sensitized solar cells, i.e., (i) by incorporation of TiO2-Au nanocomposites, where Au nanoparticles of different sizes are embedded into a TiO2 matrix, and (ii) variation of temperature at which quantum dots are deposited (iii) by postdeposition annealing of QD-sensitized photoanode in Ar atmosphere. We have used electrophoretic deposition technique to develop the nanocomposite-doped photoanode. High-resolution transmission electron microscopy confirms that the Au particles dispersed in the TiO2 matrix vary from 2 to 50 nm and PbS quantum dot size ranges 3.5–6 nm. The optical absorption of PbS quantum dot-sensitized TiO2-Au-incorporated photoanode is substantially enhanced as confirmed from the UV-visible absorption spectra measurements. The current-voltage characteristics of all the plasmonic quantum dot-sensitized solar cells under illumination (100 mW/cm2, AM 1.5) show significant improvement in power conversion efficiency using the abovementioned strategies. The maximum power conversion efficiency observed in PbS quantum dot-based quantum dot-sensitized solar cells is 7.0%. Electroimpedance spectroscopy has been utilized to understand the recombination kinetics in these solar cells.
